Instrumental treatments for benign prostatic obstruction.

PURPOSE OF REVIEW: The need to treat increasing numbers of patients with symptomatic benign prostatic obstruction has led to the continuous development of various novel or modified instrumental procedures with minimal invasiveness. The aim of the following review is to provide an overview of the current research focused on the complications and morbidity of instrumental treatment options for symptomatic benign prostatic obstruction. RECENT FINDINGS: A systematic Medline database search, over the past 12 months of the literature with a focus on articles about surgical treatment for benign prostatic obstruction or benign prostatic hyperplasia, provided some interesting new data concerning laser prostatectomy (holmium laser enucleation of the prostate and photoselective vaporization of the prostate) and transurethral resection of the prostate using bipolar electrocautery systems available for the review. SUMMARY: The data of this review period confirmed a favorable safety profile of holmium laser enucleation of the prostate for treating patients with comorbidities. Photoselective vaporization of the prostate seems to be an efficient technique with a favorable safety profile. Its long-term potential, however, has to be confirmed by randomized controlled studies. Transurethral resection of the prostate using bipolar electrocautery systems appears to offer the advantages of improved hemostasis and the ability to avoid transurethral resection syndrome. More randomized comparisons, however, need to be undertaken before an accurate general picture is available.

[Causes of erectile dysfunction after transurethral resection of hyperplastic prostate and its prophylaxis].

The study was made of 60 sexually active patients with prostatic hyperplasia after monopolar transurethral operations (mean age 61.3 years). 30 patients entered a control group, 30 ones--the study group. The latter received 10 mg vardenafil each other day for 7 weeks after the intervention. The patients filled in questionnaire, underwent dopplerography and electromyography of the penis. Questionnaire said that erection was worse after operation in 6 (20%) patients (p < 0.01) of the control group and none of the study group. The latter also showed better circulation. All the men with postoperative erectile dysfunction (ED) had electromyographic signs of impaired autonomic innervation of the penis. Thus, ED after transurethral operations for prostatic hyperplasia is primarily neurogenic and is seen in 20% operated patients. Early vardenafil therapy is effective in prevention of postoperative ED.

A prospective randomized controlled trial of hybrid laser treatment or transurethral resection of the prostate, with a 1-year follow-up.

OBJECTIVE: To compare the clinical outcome after hybrid laser treatment of the prostate, combining potassium titanyl phosphate (KTP) and Nd:YAG lasers, with transurethral resection of the prostate (TURP). PATIENTS AND METHODS: A prospective randomized trial was conducted to compare laser treatment and TURP. The hybrid laser treatment technique involved performing initial 30 W KTP vaporizing bladder neck incisions and prostatotomies followed by a 'free-paint' application of 60 W Nd:YAG coagulation energy. Patients were re-assessed after 6 weeks, 6 months and 1 year, using the International Prostate Symptom Score (IPSS) and uroflowmetry. TURP was conducted using conventional methods. RESULTS: In all, 204 patients were randomized into the study; at 6 weeks there were significant differences between the groups for the IPSS (12.4 vs 9.1, P=0.001) and maximum urinary flow rates (16.1 vs 20.8 mL/S, P<0. 001) in favour of the TURP group. At 6 months and one year this difference had disappeared. Similar numbers of patients in each group complained of bothersome postoperative urinary symptoms (23% vs 19%). Blood transfusions (5% vs none) and urethral strictures (9% vs 2%) were more common after TURP, whereas more early infective complications occurred after hybrid laser treatment (24% vs 5%). Only one patient in each group required re-operation because of poor resolution of symptoms. CONCLUSIONS: At one year, hybrid KTP/Nd:YAG laser treatment of the prostate was equivalent to TURP in the improvements in IPSS, maximum urinary flow rate and post-void residual urine.

Persistent vesicourethral dysfunction following radical surgery for rectal carcinoma: urodynamic features and potential abatement with modified sphincterotomy (radical transurethral resection of the prostate).

BACKGROUND: Vesicourethral function returns after radical rectal surgery during the first year but rarely progresses after 1 year. We examined the urodynamics of patients whose voiding dysfunction remained after 1 year, and treated several with a modified sphincterotomy procedure similar to radical transurethral resection of the prostate. METHODS: We analyzed the urodynamic features of vesicourethral dysfunction in 16 male patients with persistent voiding dysfunction for more than 1 year following radical surgery for rectal carcinoma. Seven patients elected to undergo radical transurethral resection of prostate (radical TUR-P) for the relief of their persistent voiding dysfunction. RESULTS: The mean bladder volume at the first desire to void was 210 mL, the mean maximal bladder capacity was 343 mL, and the mean vesical compliance (Cves) was 27.1 mL/cm H2O. All patients demonstrated either vesical denervation supersensitivity (Vds) or uninhibited contraction. The mean maximal urethral closure pressure was 43.9 cm H2O, and urethral denervation supersensitivity was found in 77.8% (7/9), and sphincter dyssynergia in 66.7% (6/9) of patients. After radical TUR-P, 5 patients became free from the use of self-catheterization, 1 patient had a reduced residual urine rate, and 1 patient was unchanged, but no patient noted a change in urinary control. CONCLUSION: Urethral dysfunction after radical rectal surgery was caused by failure of the bladder to empty along with an underactive detrusor. Radical TUR-P was effective in restoring voiding function in a selected group of these patients.

Transurethral microwave thermotherapy versus transurethral resection for benign prostatic hyperplasia: preliminary results of a randomized study.

The results of transurethral microwave thermotherapy (TUMT) were compared in a prospective randomized study with those of transurethral resection (TURP) in patients with benign prostatic obstruction. In this preliminary report, 39 and 40 patients treated with TUMT and TURP, respectively, were followed between 2 and 12 months. Statistically significant improvements in symptom score, maximum flow rate, residual urine and maximum bladder capacity at cystometry were observed in both groups. The improvements were more pronounced in the TURP group, but major complications were more frequent in this group. Results are compared to other published studies.

Interstitial laser coagulation versus transurethral resection of the prostate for benign prostatic enlargement--a prospective randomized study.

OBJECTIVE: Interstitial laser coagulation (ILC) of the prostate is a minimally invasive method for treating symptomatic benign prostatic enlargement (BPE). We performed a prospective randomized study to compare the clinical outcomes of ILC and transurethral resection of the prostate (TURP). MATERIAL AND METHODS: Between December 1997 and February 2000, 38 patients with moderate-to-severe symptomatic BPE were included in the study. Seven were subsequently excluded due to intercurrent disease or protocol violation and the remaining 31 were randomized to either TURP (n=11) or ILC (n=20). A suprapubic tube was inserted in all ILC-treated patients, and ILC was performed as an outpatient procedure when feasible. Data were recorded preoperatively and at 3-month and 1-year follow-up. The assessment parameters were International Prostate Symptom Score (IPSS), uroflow, prostate volume determined by means of transrectal ultrasound and postvoid residue. RESULTS: At 1-year follow-up, uroflowmetry indicated a more pronounced increase in peak urinary flow rate (Qmax) in the TURP patients than in the ILC subjects (p<0.02). Differences in postvoid residue, IPSS and prostate volume between the two treatments could not be evaluated due to the small number of patients in each group. Postoperative urinary tract infections occurred in 13 ILC patients but in only one TURP subject, and catheterization was done for 24 days after ILC and for 2 days after TURP. The study was ended prematurely due to the prolonged postoperative catheterization and the high rate of urinary tract infections in the ILC patients. CONCLUSIONS: At 1-year follow-up, the increase in Qmax was smaller in the ILC subjects than in the TURP patients. The ILC subjects had comparatively more postoperative urinary tract infections and more prolonged postoperative catheterization than the TURP patients.

Photoselective vaporization (PVP) versus transurethral resection of the prostate (TURP): a prospective bi-centre study of perioperative morbidity and early functional outcome.

OBJECTIVES: To compare the early follow-up and perioperative morbidity of photoselective vaporization (PVP) and transurethral resection of the prostate (TURP) in patients (pts.) suffering from lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). MATERIAL AND METHOD: 101 pts. underwent PVP (n = 64) and TURP (n = 37) in a prospective, non-randomized bi-centre trial. Inclusion criteria were identical at both centres. Primary outcome parameters were maximum urinary flow rate (Q(max)), post-void residual volume (V(res)), International Prostate Symptom Score (IPSS). Secondary outcomes included intraoperative surgical parameters and perioperative and post-discharge morbidity. RESULTS: Baseline characteristics of both groups were similar. Operating time was slightly shorter in the TURP group (p = 0.047). During TURP significant more irrigation solution was used (p < 0.001). Decrease of serum haemoglobin (p = 0.027) and serum sodium (p = 0.013) was larger after TURP. Catheter drainage was removed significant earlier after PVP than after TURP (p < 0.001). Outcome of Q(max), and IPSS were similar in both groups within 6 months. The sort of perioperative complications was different in both groups, however overall cumulative perioperative morbidity was comparable (PVP 39.1% versus TURP 43.2.1%; ns). CONCLUSION: PVP provides excellent intraoperative safety, instant tissue removal, and immediate relief from obstructive voiding symptoms, similar to TURP. Early outcomes 6-months after PVP and TURP are comparable.

The catheterized patient undergoing transurethral resection of the prostate: a survey of the current practice of British urologists.

OBJECTIVE: To determine, using a postal questionnaire survey of practising British consultant urologists, the duration and type of antibiotic deemed most effective in patients with an existing indwelling catheter before transurethral resection of the prostate (TURP), as the value of prophylactic antibiotics before TURP is well recognized, but no data are available. METHODS: A questionnaire was posted to each of the 321 practising consultant urologists listed in the handbook of the British Association of Urological Surgeons (1998). A hypothetical situation in the opening statement proposed 'a patient with an indwelling catheter is to undergo TURP'. The type, timing and duration of prophylactic antibiotic usage were elicited by circling the appropriate response from a choice of several possibilities. RESULTS: In all, 250 questionnaires were returned; 98% of respondents recognized the importance of the prophylactic use of antibiotics in catheterized patients undergoing TURP, and routinely use them. Most urologists (53%) use more than one dose, with most of these preferring a second dose on catheter removal (60%). CONCLUSION: The magnitude and diversity of response suggests uncertainty about the appropriate prophylaxis in such patients, and the need for further studies to clarify this situation.

Factors influencing post-operative hospital stay after transurethral resection of the prostate gland.

The influence of 12 clinical and social factors on the length of post-operative stay in hospital after transurethral resection of the prostate was investigated in 100 patients. Using a multiple binary regression analysis, the factors significantly associated with a post-operative stay exceeding 6 days were: patient's age greater than 70 years (P less than 0.005), the presence of existing cardiovascular disease (P less than 0.005) and the weight of the prostate gland resected greater than 10 g (P less than 0.005). The first two factors are useful in providing a prediction of prolonged post-operative stay. The results indicate that those factors associated with a prolonged post-operative stay are beyond the control of the clinician.

Incidence of thromboembolism after transurethral resection of the prostate (TURP)--a study on TED stocking prophylaxis and literature review.

OBJECTIVE: To assess the incidence of clinically evident pulmonary emboli and deep vein thromboses in patients undergoing transurethral resection of the prostate (TURP) with the routine use of graduated elastic compression stockings (TED) in all patients and the addition of low-dose heparin in selected high-risk patients. PATIENTS AND METHOD: A retrospective analysis of clinically evident thromboembolic complications within 4 weeks of operation in 883 patients operated in a single hospital during a 4-year period. RESULTS: Four patients (0.45%) developed pulmonary emboli (PE), of which two (0.23%) were fatal. There was one clinically evident deep vein thrombosis (DVT) in a high-risk patient (0.11%). None of the 14 high-risk patients receiving additional low-dose heparin required a blood transfusion. CONCLUSION: Clinical thromboembolic complications following TURP are rare. TURP patients have a low risk for DVT, but an intermediate risk for pulmonary emboli. Pulmonary emboli may occur without identifiable risk factors and despite TED stocking prophylaxis.

The effect of prior transurethral resection of the prostate on post radiation urethral strictures and bladder neck contractures.

Patients treated for prostate cancer from 1975-1982 were reviewed to assess if pre-irradiation transurethral resection of the prostate (TURP) predisposed to the formation of post treatment urethral strictures or bladder neck contractures. A total of 368 patients were treated with external beam irradiation delivered by a linear accelerator or 125I interstitial implants. Of the 253 patients treated by external beam, 138 patients had a history of at least one TURP before treatment. Implants were performed in 115 patients and 57 had a history of TURP before treatment. A total of 40 patients from both groups developed post treatment complications of urethral strictures or bladder neck contractures. Three patients developed both complications. An analysis of the 40 patients revealed that 29 (72.5%) patients had a TURP performed within a median time of 33 days prior to their initiation of radiation therapy. Of 195 patients in the prior TURP group, 29 (15%) developed one or both complications. Only 11 (6%) of the 173 patients in the non-TURP group developed one or both complications. This comparison was statistically significant with a p value of .025. Various factors analyzed including the treatment regimen, histologic grade, stage of disease, and volume of prostatic tissue removed at surgery did not show any positive correlation. Multiple TURP's were evaluated for greater distribution to the incidence of post treatment complications. The prior TURP group of 195 patients contained 60 with a history of at least two TURPs before radiation therapy. Eleven (18.3%) developed one or both complications. Of the 135 patients in the single TURP group, 18 (13.3%) developed complications. This was not statistically significant. Therefore, we concluded that the initial TURP was its mechanical description of mucosa and resultant scarring is a predisposing risk for development of urethral strictures or bladder neck contractures. Review of the literature concerning time sequence for healing of the urethra shows 4-6 weeks to be appropriate interval between surgery and radiation.

Transurethral resection of the prostate among Medicare beneficiaries in the United States: time trends and outcomes. Prostate Patient Outcomes Research Team (PORT).

OBJECTIVES: The purpose of this study was to examine the epidemiology of transurethral resection of the prostate (TURP) and associated risks among Medicare beneficiaries during the period of 1984 to 1990. METHODS: Medicare hospital claims for a 20% national sample of Medicare beneficiaries were used to identify TURPs performed during the study period. All reported rates were adjusted to the composition of the 1990 Medicare population. Risks of mortality and reoperation were evaluated using life-table methods. RESULTS: The age-adjusted rate of TURP reached a peak in 1987 and declined thereafter. Similar trends were observed for all age groups. In 1990, the rates of TURP (including all indications) were approximately 25, 19, and 13 per 1000 for men over the age of 75, 70 to 74, and 65 to 69, respectively. The 30-day mortality following TURP for the treatment of benign prostatic hyperplasia (BPH) decreased from 1.20% in 1984 to 0.77% in 1990 (linear trend, p = 0.0001). The cumulative incidence of a second TURP among men with BPH has likewise decreased steadily over time; in this study, the average was 7.2% over 7 years (5.5% when the indication for the second TURP was restricted to BPH only). CONCLUSIONS: The rate of TURP has been declining since 1987, conceivably due to increasing availability of alternative treatments or changes in treatment preferences of patients and physicians. Over the same period, the outcomes following TURPs have improved, perhaps due to improved surgical care and changes in patient selection.

Surgical management for benign prostatic hyperplasia: indications, techniques, and results.

Diagnostic possibilities have improved with urodynamic studies and rectal ultrasound. Many more patients with benign prostatic hyperplasia (BPH) need urodynamic investigation because 25% of men with symptoms have no prostatic obstruction. Ultrasound is quite accurate in choosing the proper surgical technique. Open prostatectomy has largely been replaced by transurethral prostate resection (TURP). One reason is better surgical equipment, but another is that patients come earlier with smaller prostates. For obstructive prostates less than 20 g, transurethral incision (TUI) of the prostate is indicated. The results are as good as those of TURP. Primary success rates for TURP, TUI, and open prostatectomy are good, but in long-term follow-up studies, 10-25% of the patients have secondary procedures after 5-10 years.

Phyllodes tumor of the prostate: long-term followup study of 23 cases.

PURPOSE: Phyllodes tumor of the prostate is a rare neoplasm of uncertain malignant potential. We studied a large series of phyllodes tumors to define the combination of histological features that are most useful for predicting patient outcome. MATERIALS AND METHODS: A total of 23 cases were obtained from our collective files from 1973 to 2002, and numerous clinical and pathological features were evaluated. A review of the reported cases of phyllodes tumor of the prostate was done. RESULTS: Patient age was 25 to 86 years (mean 55) and they usually presented with urinary obstructive symptoms and hematuria. The diagnosis was made in 18 tumors by transurethral resection, in 2 by enucleation, in 1 by tumor resection and in 2 by prostatectomy. We analyzed 5 histological features, including cellularity (scale of 1 to 3), cytologic atypia (scale of 1 to 3), the number of mitotic figures per 10 high power fields, the stroma-to-epithelium ratio (low or high) and necrosis (present or absent). This combination of features revealed that 14 cases were low grade phyllodes tumor, 7 were intermediate grade and 2 were high grade with the high grade cases characterized by increased cellularity, severe cytological atypia, more than 5 mitotic figures per 10 high power fields and a high stroma-to-epithelium ratio, indicating stromal overgrowth. Immunohistochemical studies of 8 tumors revealed consistent, intense cytoplasmic immunoreactivity in stromal cells for vimentin and actin, in luminal epithelial cells for prostate specific antigen, prostatic acid phosphatase and broad-spectrum keratin AE1/AE3, and in basal cells for high molecular weight keratin 34beta-E12. Recurrence was seen in 7 of 14 low grade tumors (50%) and in 1 patient low grade sarcoma emerged with subsequent distant metastases 14 years after initial diagnosis following 5 recurrences. Recurrence was seen in 6 of 7 intermediate grade tumors and low grade sarcoma emerged with subsequent abdominal wall metastases in 1 patient 11 years after initial diagnosis following 3 recurrences. The phyllodes tumor recurred in each patient with high grade tumors with a time to first recurrence of 6 and 0.2 years, respectively. Distant metastases developed in these 2 patients. CONCLUSIONS: Histological grading of prostatic phyllodes tumors is predictive of short-term outcome based on the combination of stromal cellularity, cytological atypia, number of mitotic figures and the stroma-to-epithelium ratio. However, these tumors usually recur after transurethral prostatic resection and they are often locally aggressive with time. The emergence of overt sarcoma and metastatic disease is more frequent than previously recognized. Complete resection at initial diagnosis appears to be indicated.

Epidural anaesthesia for transurethral resection of the prostate in a patient with carcinoid syndrome.

The anaesthetic management of a 63-year-old patient with carcinoid syndrome presenting for transurethral resection of the prostate (TURP) is described. Before surgery antibradykinin, antiserotonin and antihistamine drugs were used in addition to SMS 201-995, a long-acting somatostatin analogue, to prevent the intraoperative release of hormones associated with this syndrome. Several techniques of general anaesthesia have achieved successful patient outcomes. Monitoring included pulse oximetry and radial artery cannulation. After infusion of Ringer's lactate, 750 ml, and 25 per cent albumin, 150 ml, an incremental epidural block with xylocaine two per cent without adrenaline was administered to achieve ideal operating conditions without any change in haemodynamic variables or oxygen haemoglobin saturation. Epidural anaesthesia seems to be a safe alternative to general anaesthesia in patients with carcinoid syndrome presenting for TURP.

Glycine 1.0% versus glycine 1.5% as irrigating fluid during transurethral resection of the prostate.

OBJECTIVE: To evaluate the potential benefits of reducing the glycine concentration from 1.5% to 1.0% in the irrigating fluid used during transurethral resection of the prostate (TURP) when 1% ethanol is used as the tracer of absorption. PATIENTS AND METHODS: The effect of 1% ethanol on the tendency for blood to haemolyse was tested in vitro and the optical condition of the irrigating fluids were studied during 10 TURPs. The breath ethanol level was monitored during 423 operations where these fluids were used in a randomized double-blind study. The incidence of 13 symptoms was recorded in the 77 patients who absorbed irrigating fluid. RESULTS: Ethanol slightly lowered the tendency for blood to haemolyse. Reducing the glycine concentration did not alter the optical conditions during TURP. The incidence of symptoms increased significantly as more glycine solution was absorbed, arterial hypotension and nausea being the most usual. Bradycardia, prickling skin sensations and feelings of uneasiness were less common when 1.0% glycine was used, but the choice of irrigating fluid had no effect on the total incidence of symptoms. CONCLUSION: We found no clear advantage in lowering the glycine concentration of the irrigating fluid used during TURP.

Impact of finasteride treatment on perioperative bleeding before transurethral resection of the prostate: a prospective randomized study.

In this preliminary, randomized study, 35 men were pretreated for 3 months with finasteride or placebo before transurethral resection of the prostate. The study was inconclusive because it did not show any benefit in terms of reducing perioperative bleeding during or after the resection but there is a need for a large, prospective, randomized study.
