Role of transurethral resection of the prostate and biopsy of the peripheral zone in the same session after repeated negative biopsies in the diagnosis of prostate cancer.
OBJECTIVE: To determine the role of the transurethral resection of the prostate (TURP) together with biopsies of the peripheral zone in the diagnosis of prostate cancer after repeated negative transrectal biopsies and increasing prostate-specific antigen (PSA) levels. METHODS: From 2003 to 2004, 43 patients, aged 53-69 yr, were seen for a history of at least two negative biopsies for prostate cancer. Thirty-five men had an increasing PSA level and underwent another set of biopsies. Seven patients had prostate cancer (20%); three were lost at follow-up and four had a Charlson comorbidity index >1. The remaining 21 were offered TURP and biopsy of the peripheral zone. Bladder outlet obstruction had no influence on decision-making. Fourteen men accepted. RESULTS: Eight patients (57%) had prostate cancer and underwent radical prostatectomy. Six cancers were detected only with TURP, one with TURP and biopsy, and one with biopsy alone. After a median of 9 mo of follow-up, two of six patients underwent rebiopsy for a rising PSA level, but no cancer was detected. CONCLUSIONS: TURP combined with a set of transrectal needle biopsies of the lateral portion of the gland is a safe procedure with a high diagnostic power after repeated negative biopsies in patients with persistently increasing PSA levels.

Can biopsy be a reliable predictor of spatial distribution of prostate cancer? Comparison of a novel biopsy regimen with radical prostatectomy findings.
OBJECTIVES: To obtain accurate spatial information on cancer distribution with a novel prostate biopsy regimen. METHODS: From 2003 to 2005, 265 patients underwent a three fan-shaped biopsy (3FSB) technique of 12 to 14 cores and sextant biopsy (SB) simultaneously. When both techniques had positive findings, and radical prostatectomy was performed, the concordance among the positive biopsy locations of the SB, 3FSB, and the combination of both (the reference standard biopsy [RSB]), the proven locations of cancer, and the presence of extracapsular extension and positive surgical margins was calculated. RESULTS: A total of 41 patients were selected, and 74 locations (left and right apex, left and right lobe) had cancer. Of these, 61 were confirmed by RSB, 58 by 3FSB, and 43 by SB with a sensitivity of 95%, 78%, and 58%, respectively. The sensitivity at the apical location was consistently greater for the 3FSB at 68% (19 of 28) compared with 40% (11 of 28) for all proven apical positive localizations and 100% (19 of 19) compared with 58% (11 of 19) for the RSB. The receiver operating characteristic analysis showed 78% accuracy for 3FSB and 68% accuracy for SB compared with the RSB. At the apex, the 3FSB and SB revealed positive surgical margins with a sensitivity of 1 and 0.4, specificity of 0.067 and 0.4, positive predictive value of 0.263 and 0.182, and negative predictive value of 1 and 0.667, respectively. CONCLUSIONS: The 3FSB had a great ability to find cancer in the gland, especially at the apex.

Prevention of chronic urinary retention in orthotopic bladder replacement in the female.
OBJECTIVE: Chronic urinary retention is a frequent complication after orthotopic bladder replacement. Herein a new technical modification to avoid voiding dysfunction is described. METHODS: Between January 1995 and January 2004, 62 women had orthotopic bladder replacement after radical cystectomy. From November 1998 on, 35 patients were operated using a new technical modification, consisting in the fixation of a large and thick flap of peritoneal and extraperitoneal tissue deriving from the posterior wall of the vagina to the edges of endopelvic fascia to create a resistant hammock under the reservoir. RESULTS: 25 women have a follow-up longer than 12 months, range 12-56, and are considered in this study. Only one, out of 25 patients, still has occasionally stress incontinence but she did not need to use pads. Two patients are incontinent at night. None of 25 patients has a residual urine volume greater than 100 ml or needed intermittent catheterization. Median bladder capacity is 350 ml, range 280-430 ml. Median creatinine level is 1.1 mg/dl, range 0.7-1.2 mg/dl. CONCLUSION: The creation of a posterior support to the neobladder, by harvesting a thick flap, has, in our series, completely avoided the occurrence of chronic urinary retention, which is the most common long-term complication of bladder replacement in the female. Our series is sufficiently large to exclude serendipity and to be compared with other series in the literature.

Laparoscopic radical cystectomy.
Laparoscopic radical cystectomy is an emerging technique. It has been proposed as an alternative to open radical cystectomy, which is the gold standard treatment of muscle-invasive or high-risk superficial bladder cancer. The experience in laparoscopic radical cystectomy reported in peer-reviewed journals account for approximately 100 cases, with a median longest follow-up of 11.5 months. Safety of the technique and cancer control need to be confirmed by a larger cohort of patients; however, after an initial analysis, it seems to be equivalent to open radical cystectomy. Equivalent does not mean better. Long-term results will determine if supposed benefits of laparoscopy overweigh the true increment of cost and time.

Pelvic floor reconstruction before orthotopic bladder replacement after radical cystectomy for bladder cancer.
Female incontinence and pelvic organ prolapse have been defined as contraindications to orthotopic bladder substitution. A 75-old-year woman with slight stress incontinence, Stage III cystocele, and vaginal vault prolapse after subtotal hysterectomy underwent radical cystectomy for Stage T2 bladder cancer. After radical cystectomy, pelvic floor integrity was restored by colposacropexy with a rectangular polypropylene mesh and an ileal reservoir to urethra was constructed. After 1 year of follow-up, she had complete daytime continence and only needed to wear a pad during the night. Her postvoid residual urine volume was constantly less than 100 mL.

Effects of a shared protocol between urologists and general practitioners on referral patterns and initial diagnostic management of men with lower urinary tract symptoms in Italy: the Prostate Destination study.
OBJECTIVE: To assess whether adopting a shared protocol between urologists and general practitioners (GPs) might change diagnostic procedures and referral patterns in the management of men with lower urinary tract symptoms (LUTS). SUBJECTS AND METHODS: Forty-five urological centres and 263 GPs in Italy participated in this prospective study. Procedures adopted by GPs for evaluating five consecutive patients (aged > or = 50 years) were compared before (phase 1) and after (phase 2) implementation of the shared protocol. An evidence-based diagnostic algorithm was developed and approved by participating urologists and presented to local GPs at a training session. Protocol modifications were allowed after discussion with GPs. Direct costs of diagnostic procedures carried out before and after implementing the protocol were calculated from the perspective of the national health service. RESULTS: In all, 903 patients were evaluable in phase 1 and 856 in phase 2. Implementation of the protocol did not change referral patterns, with about half the patients being managed entirely by GPs. The use of a digital rectal examination by GPs increased from 32% to 41%, use of transrectal and suprapubic ultrasonography decreased from 33% to 23% and 53% to 44%, respectively, (all P < 0.001) and use of the International Prostate Symptom Score increased from 4.5% to 23.1% (P < 0.001). Overall, protocol-recommended tests were used more frequently, while those not recommended decreased after implementing the protocol. However, overuse of the tests not recommended (i.e. urine culture and free/total prostate specific antigen ratio) remained high. The mean cost per patient of diagnostic procedures ordered by GPs decreased from Euros 71.82 to Euros 61.93, with Euros 9.9 saved for each patient. CONCLUSION: Our intervention failed to decrease the percentage of cases of LUTS being referred to specialists, but was moderately effective in inducing changes in the diagnostic management by GPs that were indicative of increased compliance with best-practice principles, and produced cost savings of 13.8%.

Long term results of excision of small renal cancer surrounded by a minimal layer of grossly normal parenchyma: review of 94 cases.
OBJECTIVE: To assess safety and effectiveness of excision of small renal cancer. METHODS: We reviewed the records of 94 patients, who underwent, from 1992 to 2001, excision of renal tumor leaving around it a thin layer of grossly normal parenchyma and adjacent perinephric fat. This technique has been called enucleoresection, as it is not a simple enucleation but neither a conventional partial nephrectomy. Patients were followed up mean routine blood examination, ultrasound and computed tomography scan every 6 months for 2 years and annually thereafter. RESULTS: Median age was 63 years (35-76). Median tumour size was 2.1cm (1.1-4.5). Clamping of renal pedicle was performed in 54 cases. Major complications included 4 cases of haemorrhage; only 1 patient required surgical exploration. Pathological stage was pT1a in 87, pT1b in 4 and pT3a in 3 patients. Surgical margins were always negative. Median follow-up was 59 months (range 10-128). Eight patients died without evidence of tumour recurrence. One pT3a patient developed distant metastases and died 2 years after surgery. Five years survival rate was 95.7% (90/94 patients), cancer specific survival rate 98.9% (93/94) and disease free survival rate 98.9% (93/94). CONCLUSIONS: Enucleoresection of small renal tumors surrounded by a minimal layer of grossly normal renal parenchyma reproduces the results of partial and radical nephrectomy with minimal morbidity.

Diagnostic procedures by Italian general practitioners in response to lower urinary tract symptoms in male patients: a prospective study.
BACKGROUND: The aim of this prospective, multicentre, observational study was to evaluate the initial diagnostic procedures for lower urinary tract symptoms (LUTS) carried out by Italian general practitioners (GPs). METHODS: Data were collected from 445 GPs in Italy regarding the initial clinical decisions and diagnostic procedures adopted for the management of 1399 male patients with LUTS aged >or= 50 years. RESULTS: 50.3% of patients were managed by the GP,4.9% were referred to the urologist immediately and 44.8% after carrying out some diagnostic procedures. A digital rectal examination was performed in only one-third of the patients, many of whom were not subsequently referred to the urologist (26.4%). Laboratory tests that are usually recommended (i.e. PSA, urinalysis and serum creatinine) were undertaken in 98.3% of patients, while tests that are generally considered optional (such as flowmetry) were undertaken in up to 64%. Other generally not recommended investigations, such as ultrasonography, were carried out in 77.2%. The mean time to diagnosis was significantly shorter when the urologist was not involved (36.0 days for GP only management vs 51.4 days for immediate referral and vs 43.4 days for delayed referral (p = 0.0003). CONCLUSIONS: Our findings show a propensity for the majority of Italian GPs to deal with LUTS patients in a primary setting without immediate referral to the urologist. In principle, this trend could be beneficial for the patient (i.e. by reducing time to diagnosis) and cost saving for the national health system. However, the diagnostic procedures selected by the GPs were not in line with best evidence practice recommendations. Shared-care protocols involving both GPs and urologists may contribute to better implementation of the guidelines on the management of LUTS and benign prostatic hyperplasia in Italy.

[Lower urinary tract symptoms and male sexual dysfunction: the multinational survey of the aging.male (MSAM-7)].
OBJECTIVES: Lower urinary tract symptoms (LUTS), which are often caused by benign prostatic hypertrophy (BPH), and sexual dysfunction are common in older men, with an overall prevalence of > 50% in men aged > 50 years. Men with LUTS have been reported to experience sexual dysfunction, including ejaculatory loss, painful ejaculation, and erectile dysfunction. This study was conducted to investigate the relationship between LUTS and sexual problems in aging men. METHODS: A large-scale, multinational survey was conducted in the US and six European countries to systematically investigate the relationship between LUTS and sexual dysfunction in older men. Detailed questionnaires were mailed to a national representative sample of men aged 50 to 80 years in each country. Selection was made on the basis of age, occupation, geographie region, and population density. LUTS and sexual function were assessed by validated symptom scales, including the International Prostate Symptom Score, the Danish Prostatic Symptom Score, and the International Index of Erectile Function. Subjects also completed a health and demographics questionnaire. RESULTS: A total of 34,800 surveys were mailed out, 14,254 were completed and returned, and 12,815 were deemed evaluable and included in the analysis. Results were consistent from one country to another. Although 90% of the men had LUTS, only 19% had sought medical help for urinary problems and only 11% were medically treated. Sexual activity was reported by 83% of the sample, with 71% reporting at least one episode of sexual activity during the previous 4 weeks. Sexual disorders and their bothersomeness were strongly related to both age and severity of LUTS. The relationship between sexual problems and LUTS is independent of comorbidities such as diabetes, hypertension, cardiac disease, and hypercholesterolemeia. CONCLUSIONS: Sexual activity is common in a majority of men over age 50 and is an important component of overall quality of life. The presence and severity of LUTS are independent risk factors for sexual dysfunction in older men. These results highlight the clinical importance of evaluating LUTS in patients with sexual dysfunction, and the need to consider sexual issues in the management of patients with benign prostatic hypertrophy.
