Paediatric penile length: a systematic review and meta-analysis.

OBJECTIVE: To assess geographical variation in stretched penile length among prepubertal boys and evaluate temporal trends over the past two decades, as defining reference values for genital organ size remains crucial for early identification of development disorders. METHODS: The PubMed, Cochrane and Scopus databases (no deadlines for publishing were imposed) were searched according to the Preferred Reporting Items for Systematic Review and Meta-analyses statement. Five authors independently extracted individual participant data and assessed the risk of bias. Studies with quantitative penile lengths were included; those involving congenital malformations were excluded. The review protocol was prospectively registered in the International Prospective Register of Systematic Reviews (registration number CRD42022335643). RESULTS: A total of 55 studies from 2000 to 2024 were evaluated, including data from 31 915 boys. Pooled mean stretched penile length estimates were 3.07 cm (95% confidence interval [CI] 2.88-3.26 cm) for the 1-week-old boys, 3.73 cm (95% CI 3.53-3.93 cm) for the 1-year-old boys, 4.69 cm (95% CI 4.49-4.88 cm) for the 2-5 year-old boys, and 5.43 cm (95% CI 5.20-5.66 cm) for the 5-10 year- old boys. When comparing data from the 2000s to the 2020s, stretched penile length decreased by 16.2% (from 3.46 to 2.90 cm), 16.3% (from 4.17 to 3.49 cm), 21.5% (from 5.31 to 4.17) and 26.2% (from 6.46 to 4.77 cm) in the 1-week-old, 1-year-old, 2-5-year-old and 5-10-year-old boys, respectively. Subgroup analysis for those aged >2 years showed significant variations by geographical region (P < 0.001). CONCLUSIONS: The present study observed large variations in penile length across geographical regions and among prepubescent boys of different ages, while also suggesting a possible decline over the past two decades.

Development and external validation of an extended repeat biopsy nomogram.

PURPOSE: We hypothesized that the outcome of repeat biopsy could be accurately predicted. We tested this hypothesis in a contemporary cohort from 3 centers. MATERIALS AND METHODS: The principal cohort of 1,082 men from Hamburg, Germany was used for nomogram development as well as for internal 200 bootstrap validation in 721 and external validation in 361. Two additional external validation cohorts, including 87 men from Milan, Italy and 142 from Seattle, Washington, were also used. Predictors of prostate cancer on repeat biopsy were patient age, digital rectal examination, prostate specific antigen, percent free prostate specific antigen, number of previous negative biopsy sessions and sampling density. Multivariate logistic regression models were used to develop the nomograms. RESULTS: The mean number of previous negative biopsies was 1.5 (range 1 to 6) and the mean number of cores at final repeat biopsy was 11.1 (range 10 to 24). Of the men 370 (30.2%) had prostate cancer. On multivariate analyses all predictors were statistically significant (p < or =0.028). After internal validation the nomogram was 76% accurate. External validation showed 74% (Hamburg), 78% (Milan) and 68% (Seattle) accuracy. CONCLUSIONS: Relative to the previous nomograms (10 predictors or 71% accuracy) our tool relies on fewer variables (6) and shows superior accuracy in European men. Accuracy in American men is substantially lower. Racial, clinical and biochemical differences may explain the observed discrepancy in predictive accuracy.

Complications and other surgical outcomes associated with extended pelvic lymphadenectomy in men with localized prostate cancer.

OBJECTIVES: More-extensive pelvic lymph node dissection (PLND) may be associated with a higher rate of complications and a longer hospital stay than more limited PLND. METHODS: Before radical retropubic prostatectomy, PLNDs were performed in 963 patients. Of these, 767 (79.6%) had >or=10 lymph nodes removed and examined (extended PLND [ePLND]), while 1-9 nodes (limited PLND [lPLND]) were removed in the remaining 196 (20.4%). Limits included external iliac, obturator, internal iliac, and iliac bifurcation. PLND-related complications and the length of hospital stay were recorded prospectively and analyzed according to the extent of PLND. RESULTS: In patients subjected to ePLND, the overall rate of complications was 19.8% versus 8.2% in those treated with lPLND (p<0.001). In individual analyses of specific complications, only the lymphocele rate was significantly higher after ePLND (10.3% vs 4.6%; p=0.01). Similarly, ePLND translated into a longer hospital stay (9.9 vs 8.2 d; p<0.001). These differences persisted when adjustment was made for prostate-specific antigen and either clinical or pathologic tumor characteristics. CONCLUSIONS: Our data indicate that, even in the hands of experienced urologic surgeons, ePLNDs are associated with higher complication rates and longer hospital stay. These detriments need to be taken into account when the staging benefit associated with ePLND is considered.

Association between erectile dysfunction and coronary artery disease: Matching the right target with the right test in the right patient.

INTRODUCTION: Evidence is accumulating in favour of a link between erectile dysfunction (ED) and coronary artery disease (CAD). This review attempts to identify which patients, among those with ED and no cardiovascular (CV) disease, should be screened for early, subclinical CAD, which coronary targets should be investigated, and which tests should be used. MATERIALS AND METHODS: A comprehensive evaluation of available published data included analysis of published full-length papers that were identified with Medline and Cancerlit from January 1988 to January 2006. RESULTS: Initial screening of patients with ED may adopt risk assessment office-based approaches to score patients into low, intermediate, or high risk of future cardiovascular events. Attention should be drawn to patients at intermediate risk. Targets for the assessment of subclinical CAD in this subset of patients should include both obstructive (flow-limiting) and nonobstructive (non-flow-limiting) CAD. Some tests address obstructive atherosclerosis by directly assessing coronary flow reserve (i.e., standard exercise stress test, rest/stress myocardial scintigraphy or echocardiography). Other tests are general measures of atherosclerosis burden (not necessarily obstructive) either in the coronary circulation (i.e., coronary calcium score by electron-beam computed tomography), or in extracoronary vessels (i.e., ankle brachial index, carotid intima-media thickness by B-mode ultrasound) as surrogate markers of CAD. Although a systematic use of these measures of nonobstructive atherosclerosis burden has not yet been recommended in the guidelines for coronary risk assessment, their use is progressively being extended from the research area to clinical practice. CONCLUSIONS: ED is definitely a vascular disorder and all men with ED should be considered at risk of CV disease until proven otherwise. Available risk assessment charts should be used to stratify (low, intermediate, and high) the coronary risk score in each patient with ED.

Association between erectile dysfunction and coronary artery disease. Role of coronary clinical presentation and extent of coronary vessels involvement: the COBRA trial.

AIMS: To investigate the prevalence of erectile dysfunction (ED) in patients with CAD according to clinical presentation, acute coronary syndrome (ACS) vs. chronic coronary syndrome (CCS), and extent of vessel involvement (single vs. multi-vessel disease). METHODS AND RESULTS: 285 patients with CAD divided into three age-matched groups: group 1 (G1, n=95), ACS and one-vessel disease (1-VD); group 2 (G2, n=95), ACS and 2,3-VD; group 3 (G3, n=95), chronic CS. Control group (C, n=95) was composed of patients with suspected CAD who were found to have entirely normal coronary arteries by angiography. Gensini's score used to assess extent of CAD. ED as any value <26 according to the International Index of Erectile Function (IIEF). ED prevalence was lower in G1 vs. G3 (22 vs. 65%, P<.0001) as a result of less atherosclerotic burden as expressed by Gensini's score [2 (0-6) vs. 40 (19-68), P=0.0001]. Controls had ED rate values similar to G1 (24%). Group 2 ED rate, IIEF, and Gensini's scores were significantly different from G1 [55%, P<0.0001; 24 (17-29), P=0.0001; 21 (12.5-32), P<0.0001] and similar to G3 suggesting that despite similar clinical presentation, ED in ACS differs according to the extent of CAD. No significant difference between groups was found in the number and type of conventional risk factors. Treatment with beta-blockers was more frequent in G3 vs. G1 and G2. In G3 patients who had ED, onset of sexual dysfunction occurred before CAD onset in 93%, with a mean time interval of 24 [12-36] months. In logistic regression analysis, age (OR=1.1; 95% confidence interval (CI), 1.05-1.16; P=<0.0001), multi-vessel vs. single-vessel (OR=2.53; 95% CI, 1.43-4.51; P=0.0002), and CCS vs. ACS (OR=2.32; 95% CI, 1.22-4.41; P=0.01) were independent predictors of ED. CONCLUSION: ED prevalence differs across subsets of patients with CAD and is related to coronary clinical presentation and extent of CAD. In patients with established CAD, ED comes before CAD in the majority by an average of 2 up to 3 years.

Validation of a nomogram predicting the probability of lymph node invasion based on the extent of pelvic lymphadenectomy in patients with clinically localized prostate cancer.

OBJECTIVE: To develop a multivariate nomogram to predict the rate of lymph node invasion (LNI) in patients with clinically localized prostate cancer according to the extent of extended pelvic lymphadenectomy (PLND), which is associated with significantly higher rate of LNI. PATIENTS AND METHODS: The study comprised 781 consecutive patients (median age 66.6 years, range 45-85) treated with PLND and radical retropubic prostatectomy (RRP) for clinically localized prostate cancer. Their median (range) prostate-specific antigen (PSA) level was 7 (1.03-49.91) ng/mL, and their clinical stages were T1c in 433 (55.4%), T2 in 328 (42%) and T3 in 20 (2.6%). Biopsy Gleason sums were <or= 6 in 514 (65.8%), 7 in 204 (26.1%) and 8-10 in 63 (8.1%). Multivariate logistic regression models were used to test the association between predictors including PSA level, biopsy Gleason sum, clinical stage, number of nodes removed and the rate of LNI. Finally, regression coefficients were used to develop a nomogram, which was internally validated with 200 bootstrap re-samples. RESULTS: The median (range) number of lymph nodes removed was 14 (2-40); LNI was detected in 71 patients (9.1%). The univariate predictive accuracy for total PSA level, clinical stage, biopsy Gleason sum and number of total nodes removed and examined was 64.2%, 59.8%, 74% and 62.9%, respectively. Except for PSA (P = 0.2), all variables were statistically significant multivariate predictors of LNI at RRP (P <or= 0.001). A nomogram based on clinical stage, PSA level, biopsy Gleason sum and the number of total lymph nodes removed was 78.6% accurate, and 1.8% more accurate than a nomogram without the number of removed lymph nodes. CONCLUSIONS: The extent of PLND is directly related to the probability of LNI. The risk of LNI increases linearly, and is proportional to the number of nodes removed and examined. The effect of the increased probability of LNI is weighted more heavily in men with more advanced clinical stage and grade.

A nomogram for staging of exclusive nonobturator lymph node metastases in men with localized prostate cancer.

OBJECTIVES: Some patients with localized prostate cancer are at risk of nonobturator lymph node invasion (NOLNI) and may require an extended pelvic lymph node dissection (ePLND). We explored the rate of exclusive NOLNI and developed a nomogram to predict it. MATERIAL AND METHODS: We mapped all ePLND specimens according to their anatomic location (obturator, external iliac, internal iliac lymph nodes) and assessed the location-specific rate of LNI in 565 patients. A multivariate logistic regression-based nomogram predicting NOLNI was then internally validated with 200 bootstrap resamples. RESULTS: Overall, 11.1% (63 of 565) had LNI and 21 (3.7%) had exclusive NOLNI. The nomogram predicting exclusive NOLNI was 80.2% accurate. The nomogram's negative predictive value was 99%, when it predicted 0-10% probability of NOLNI. This approach could allow the omission of an ePLND in 350 of 565 (61.9%) patients and still correctly stage 85.8% of NOLNI cases. CONCLUSIONS: Our nomogram-based approach offers the possibility of identifying men who are at virtually zero risk of exclusive NOLNI. In these men, an ePLND may be safely avoided.

Clitoral circulation in postmenopausal women with sexual dysfunction: a pilot randomized study with hormone therapy.

OBJECTIVE: The aim of the present pilot, randomized, study was to assess hemodynamic status of clitoral erectile tissues in postmenopausal women reporting female sexual dysfunction (FSD), namely libido and arousal disorders, under hormone therapy (HT). Vaginal health and sexual function were also investigated. STUDY DESIGN: Fifty patients presenting for clinical evaluation of menopausal status and suffering from FSD were randomly assigned to receive tibolone (2.5 mg) or 1 mg 17beta-estradiol .5 mg NETA (EPT) for 6 months. The observational period lasted 7 months during which women underwent to duplex Doppler ultrasonography to obtain clitoral hemodynamic data, were evaluated by using the vaginal health score index (VHIS) and filled in the two-factor Italian McCoy female sexuality questionnaire (MFSQ). RESULTS: Tibolone significantly increased clitoral peak systolic and end diastolic velocity (p<.001 for both), while no significant difference was evident in clitoral circulation of women under EPT at the end of the study. Both tibolone and EPT significantly increased VHIS (p<.001), an effect already evident following 3 months of HT. The atrophic state was significantly improved at 6 months (p<.001) with no significant differences between the two HT regimens. After 3 months, both tibolone and EPT significantly increased the sexuality score (p<.001, for both), but such an effect was significantly more pronounced in FSD women treated with tibolone in comparison with those assuming EPT (p<.002). Between the 3rd and the 6th month, tibolone caused a further significant improvement of sexuality score (p<.001), while women under EPT did not show any significant further change displaying a lower score (p<.001) at the end of the study in comparison with women assuming tibolone. CONCLUSIONS: Clitoral circulation in postmenopausal women reporting FSD is significantly increased under tibolone in comparison with EPT with a better improvement of sexual function, as measured by MFSQ, following 6 months of treatment.

Holmium laser enucleation of the prostate versus open prostatectomy for prostates >70 g: 24-month follow-up.

OBJECTIVE: Prospectively evaluate perioperative outcomes and 2-yr follow-up after holmium laser enucleation (HoLEP) and standard open prostatectomy (OP) for treating benign prostatic hyperplasia-related obstructed voiding symptoms, with prostates >70 g. METHODS: From March 2003 to December 2004, 80 consecutive patients were randomised for surgical treatment with HoLEP (n=41) or standard OP (n=39). All patients were preoperatively assessed with International Prostate Symptom Score and International Index of Erectile Function questionnaires and complete urodynamic evaluation. Intraoperative and perioperative parameters such as blood loss, catheter removal, and hospital stays were assessed. Early and late complications were recorded. Patients were evaluated at 1-, 3-, 12-, and 24-mo follow-ups with the same tests. RESULTS: Operating room time was significantly shorter for the OP group (72.09+/-21.22 min vs. 58.31+/-11.95 min, p<0.0001); catheter removal (1.5+/-1.07 d and 4.1+/-0.5 d, p<0.001) and hospital stay (2.7+/-1.1 d vs. 5.4+/-1.05 d, p<0.001) were shorter in the HoLEP group. Blood loss was less and blood transfusions fewer in the HoLEP group (p<0.001). In both groups urodynamic and uroflowmetry findings improved from baseline, were still evident at the 24-mo follow-up, and were comparable between the two groups. Late complications were also comparable. CONCLUSIONS: HoLEP is a feasible technique for treating large prostates. Functional results are similar to OP at the 2-yr follow-up. Reduced catheterisation, hospital stay, and blood loss make HoLEP an attractive option for the treatment of large prostates.

Women's sexual dysfunction: a review of the "surgical landscape".

OBJECTIVES: To assess the impact of urogynaecologic surgery for stress urinary incontinence, oncologic pelvic surgery, and hysterectomy on women's overall sexual health. METHODS: We used Ovid and PubMed (updated January 2006) to conduct a literature electronic search on MEDLINE that included peer-reviewed English-language articles. We analysed all studies identified that provided any functional outcome data about urogynaecologic surgery for the treatment of stress urinary incontinence, radical cystectomy for bladder cancer, surgery for rectal cancer, and hysterectomy. Because of the substantial heterogeneity of outcome measures and follow-up intervals in case studies, we did not apply meta-analytic techniques to the data. RESULTS: Most studies showed that either urogynaecologic or oncologic pelvic surgery may have a significant impact on women's sexual health. Epidemiology varied widely among the studies and reported either improvement or impairment of postoperative sexual functioning, due to different definitions, study designs, and small cohorts of patients. An increasing number of studies have prospectively examined this issue and have found often controversial findings about the role of pelvic and perineal surgery in women's sexual health. CONCLUSIONS: Although numerous controversies exist, data demonstrate an overall positive impact of the surgical repair for stress urinary incontinence on resolution of coital incontinence, coupled with an improvement of overall sexual life. In contrast, genitourinary and rectal cancers are commonly associated with treatment-related sexual dysfunction, but few studies rigorously assessed women's postoperative sexual function after major oncologic pelvic surgery. Data about the functional outcome after hysterectomy are often contradictory. Adequately powered prospective clinical trials are needed.

Validation of a nomogram predicting the probability of lymph node invasion among patients undergoing radical prostatectomy and an extended pelvic lymphadenectomy.

INTRODUCTION: Our goal was to develop and internally validate a nomogram for prediction of lymph node invasion (LNI) in patients with clinically localized prostate cancer undergoing extended pelvic lymphadenectomy (ePLND). METHODS: 602 consecutive patients (mean age 65.8 years) underwent an ePLND, where 10 or more nodes were removed. PSA was 1.1-49.9 (median 7.2). Clinical stages were: T1c in 55.6%, T2 in 41.4% and T3 in 3%. Biopsy Gleason sums were: 6 or less in 66%, 7 in 25.4%, 8-10 in 8.6%. Multivariate logistic regression models tested the association between all of the above predictors and LNI. Regression-based coefficients were used to develop a nomogram predicting LNI and 200 bootstrap resamples were used for internal validation. RESULTS: Mean number of lymph nodes removed was 17.1 (range 10-40). LNI was detected in 66 patients (11.0%). Univariate predictive accuracy for total PSA, clinical stage and biopsy Gleason sum was 63%, 58% and 73%, respectively. A nomogram based on clinical stage, PSA and Biopsy Gleason sum demonstrated bootstrap-corrected predictive accuracy of 76%. CONCLUSIONS: A nomogram based on pre-treatment PSA, clinical stage and biopsy Gleason sum can highly accurately predict LNI at ePLND.

Can phosphodiesterase type 5 inhibitors cure erectile dysfunction?

INTRODUCTION AND OBJECTIVES: To systematically analyze and review the available evidence about the potential role of chronic administration of phosphodiesterase type 5 (PDE-5) inhibitors for the cure of erectile dysfunction (ED) based on clinical and basic science data. METHODS: Analysis of published full-length papers that were identified with Medline and Cancerlit from January 1993 to September 2005. Abstracts published in the journals European Urology, the Journal of Urology, the International Journal of Impotence Research, and the Journal of Sexual Medicine as official proceedings of internationally known scientific societies held in the same time period were also assessed. RESULTS: Chronic administration of PDE-5 inhibitors have reportedly been associated with increased persistent vascular and endothelial function--which represents a key factor in maintaining vascular tone and inducing vasodilation--by increasing the level of endothelial cGMP generated by activation of endothelial nitric oxide. Clinical studies have revealed a potential protective role of these compounds on endothelial function in short- and long-term assessments. Several studies based on animal models have provided direct experimental support for the role of PDE-5 inhibitors in improving the structure and function of the cavernosal tissue and have suggested potential molecular mechanisms involved. CONCLUSIONS: Although evidence increasingly supports the potential role of chronic administration of PDE-5 inhibitors for improving erectile function in patients affected by ED, long-term data are lacking. However, data available from animal models support the evidence of potential benefits induced on endothelial function by chronic exposure to PDE-5 inhibitors.

Baseline potency in candidates for bilateral nerve-sparing radical retropubic prostatectomy.

OBJECTIVES: To assess the baseline erectile function (EF) of patients with clinically localized prostate cancer (pCa), who are candidates for a bilateral nerve-sparing radical retropubic prostatectomy (BNSRRP) to (a) objectively rate the preoperative self-reported subjective patient's EF and (b) investigate possible correlations between preoperative EF and demographic data and comorbidities. MATERIALS AND METHODS: Two-hundred-thirty-four patients, who verbally self-reported they were preoperatively fully potent and strongly motivated to maintain postoperative EF, underwent a BNSRRP. A comprehensive medical and sexual history was obtained on hospital admission the day prior to surgery. Subjectively reported potency rate was compared with the scores of the International Index of Erectile Function (IIEF). RESULTS: The EF domain of the IIEF showed a baseline normal EF in only 43% of the subjects. In contrast, 13% had a mild erectile dysfunction (ED), 8% had a mild to moderate ED, 8% complained of a moderate ED, and as many as 28% reported severe EF impairment. Interestingly, 38% of the patients with severe ED did not attempt any intercourse during the last 4 weeks prior to surgery. CONCLUSIONS: A significant proportion of patients with clinically localized pCa and self-reported total potency already had suffered from ED preoperatively. Incorrect timing of questionnaires administration, the potential influence of preoperative patient's psychological distress, and the implication of the patient's partner's psychological and sexual health may be contributing factors to the contradictory finding. The preoperative use of validated questionnaire may help to identify patients who can actually expect to regain potency following a BNSRRP.

Radical prostatectomy after previous prostate surgery: clinical and functional outcomes.

PURPOSE: Radical prostatectomy has progressively become an elective treatment for primary localized prostate cancer as well as for incidental or subsequent prostatic cancer after previous surgery for obstructive benign disease. This increased acceptance opens concerns about oncological and functional outcomes. MATERIALS AND METHODS: Between July 1999 and August 2003, 109 patients underwent radical retropubic prostatectomy for prostate cancer as a second line approach after surgery for primary bladder outlet obstruction. Of these patients 88 had undergone previous transurethral resection of the prostate and 21 had undergone open prostatectomy. Incidental and delayed prostate cancer was detected in 71 and 38 cases, respectively. Perioperative and postoperative morbidity was evaluated in all patients, while postoperative functional outcomes were assessed by a subjective questionnaire in 43. RESULTS: As a second surgery, radical retropubic prostatectomy was generally more complex technically and it resulted in longer operative time compared to radical surgery in naïve patients. In contrast, early and delayed postoperative morbidity increased moderately. Complete urinary continence was documented in 32 (74%) and 37 patients (86%) at the 6 and 12-month follow-ups, respectively. In this patient cohort adequate erectile function was reported by 12%. CONCLUSIONS: Radical retropubic prostatectomy can be performed safely after previous prostate surgery for bladder outlet obstruction. However, a consistent surgical background in prostate surgery is needed to manage frequently unexpected difficulties. Candidates for second line prostate surgery should be informed that functional results are less predictable and satisfactory than those achieved after the same surgical approach in naïve patients.

Urodynamics after TURP and HoLEP in urodynamically obstructed patients: are there any differences at 1 year of follow-up?

OBJECTIVES: To compare urodynamic findings after holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP) for the treatment of benign prostatic hyperplasia-related bladder outlet obstruction. METHODS: From January to October 2002, 100 consecutive patients with benign prostatic hyperplasia with obstructive lower urinary tract symptoms were randomized to surgical treatment with either HoLEP (group 1, n = 52) or TURP (group 2, n = 48). All patients were preoperatively assessed using the International Prostate Symptom Score and quality-of-life question, total serum prostate-specific antigen measurement, transrectal ultrasonography, and complete urodynamic study. The operative time, catheterization time, and overall hospital stay were also recorded for both groups. All patients were assessed at 1, 6, and 12 months postoperatively using a complete urodynamic evaluation. RESULTS: All patients were obstructed preoperatively (Schäfer grade greater than 2). Both groups were comparable in terms of age, total serum prostate-specific antigen level, International Prostate Symptom Score, and urodynamic results. At 1, 6, and 12 months of follow-up, no statistically significant differences were recorded in terms of detrussor pressure at maximal urinary flow rate, Schäfer grade (linear passive urethral resistance relation), maximal urinary flow rate, International Prostate Symptom Score, and quality-of-life score. In the HoLEP group, the catheterization time and hospital stay were significantly shorter. Transitory lower urinary tract symptoms after 3 months of follow-up and dysuria were more frequent in the HoLEP group than in the TURP group, although at 12 months of follow-up, the results were comparable. CONCLUSIONS: Both HoLEP and TURP were equally effective in relieving bladder outlet obstruction. Although associated with greater early self-resolving irritative symptoms, HoLEP can guarantee a shorter catheterization time and hospital stay with longer operative times, proposing itself as an attractive alternative to standard TURP.

Holmium laser enucleation versus open prostatectomy for benign prostatic hyperplasia: an inpatient cost analysis.

OBJECTIVES: To compare the cost of open transvesical prostatectomy (OP) with that of holmium laser enucleation (HoLEP) in the treatment of bladder outlet obstruction (BOO) attributed to benign prostatic hyperplasia. METHODS: From February to May 2004, 63 consecutive patients with symptomatic benign prostatic hyperplasia in a large prostate (70 to 220 g) and documented BOO were randomized to surgical treatment with OP (29 in group 1) or HoLEP (34 in group 2). All costs associated with the procedures during the hospital stay were recorded prospectively, and a cost-effectiveness analysis of the critical perioperative (ie, intraoperative and postoperative to hospital discharge) data was performed. RESULTS: The cost analysis showed a mean perioperative cost of 2868.9 euros (3556.3 dollars) for group 1 and 2356.5 euros (2919.4 dollars) for group 2. A direct comparison analysis showed that the most significant cost factors were the operative time (average 16.1% and 25.1% to the cost of OP and HoLEP, respectively), operating room surgical setup/disposables, including laser fiber and resectoscope loop in group 2 (average 13.3% and 29.3% to the cost of OP and HoLEP, respectively), and length of postoperative hospital stay (average 53.3% and 32.0% to the cost of OP and HoLEP, respectively). Overall, the hospitalization cost of HoLEP was 9.6% less than that for OP. CONCLUSIONS: Our data have demonstrated that HoLEP is associated with a significant hospital net cost savings compared with OP in patients undergoing surgery for symptomatic benign prostatic hyperplasia in large glands.

Bone metastases are infrequent in patients with newly diagnosed prostate cancer: analysis of their clinical and pathologic features.

OBJECTIVES: To investigate the clinical and pathologic characteristics of patients with bone metastases identified at the time of newly diagnosed prostate carcinoma at biopsy. METHODS: From November 2002 to May 2004, 1587 consecutive patients had a pathologic diagnosis of prostate cancer and underwent conventional technetium-99m methylene diphosphonate scintigraphy of the entire body. The clinical and pathologic features of those patients with positive bone scan findings (group 1) were compared with those of a subcohort of 372 patients with negative bone scan findings performed at the same nuclear medicine department (group 2). RESULTS: A retrospective complete data collection was available for 1242 of 1587 patients. Bone metastases were found in 31 patients (2.5%). As expected, patients with skeletal metastases had a significantly greater mean serum total prostate-specific antigen level, and a Gleason sum of 8 or 9 was significantly more frequent in the pathologic findings of these subjects. Group 1 patients had a significantly greater prevalence of previous nonprostate primary neoplasms (chi-square 12.74, df = 1, P = 0.0004) and reported a greater prevalence of current use of H2 blockers for the treatment and prevention of gastroesophageal reflux disorders (chi-square 37.52, df = 1, P < 0.0001) than did group 2 patients. CONCLUSIONS: Our data have confirmed that bone metastases are more frequent in patients with high prostate-specific antigen levels and poorly differentiated tumors at biopsy regardless of the patient's age. A history of previous nonprostate primary neoplasms and the use of H2 blockers seemed to be more prevalent in those patients with bone metastases at diagnosis.
