Bladder neck strictures after radical retropubic prostatectomy: still an unsolved problem

Robotic Assisted Radical Prostatectomy After Prior Transurethral Resection of Prostate: An Analysis of Perioperative, Functional, Pathologic, and Oncological Outcomes

BACKGROUND

We performed a retrospective comparison of surgical, oncological, and functional outcomes following robotic assisted radical prostatectomy between patients who have undergone prior TURP to TURP naïve patients.

METHODS

Past robotic prostatectomy hospital data was scrutinized to form two matched groups of patients: those who have undergone prior TURP and TURP naïve patients. The perioperative and pathological data, along with functional and oncological outcomes, over a period of 3 years were compared between groups.

RESULTS

Compared to TURP-naïve patients, prior TURP patients experienced longer RALP times (p<.001), increased incidence of bladder neck reconstruction (p=0.03), greater blood loss (p= 0.0001), and lesser nerve sparing (p<0.01). Complication rates (p=0.3), positive surgical margin (p=0.4), extracapsular disease (p=0.3), or seminal vesicle invasion (p=0.1) were comparable between groups. Continence (p=0.5) and potency (p=0.1) at 1 year were not different between groups. Biochemical recurrence rates were not different at 3 years (p=0.9). Diabetes slowed recovery of continence in patients with prior TURP compared to TURP naïve patients until 6 months after surgery.

CONCLUSION

Although prior TURP makes subsequent robotic prostatectomy more technically demanding, it can be safely performed by experienced surgeons without compromising long term functional or oncological outcomes.

Minimal invasive management of bladder neck contracture using Allium round posterior stent: the long-term results

Background

The purpose of this study was to assess the long-term clinical efficacy of temporary, Allium round posterior stent (RPS) used for treatment of recurrent bladder neck contracture (BNC).

Methods

Records of 42 patients with recurrent BNC who underwent Allium RPS placement after bladder neck incision, between 2009 and 2019, were analyzed. After stent removal, the success criteria for Allium RPS treatment were defined as: no evidence of stricture on urethrogram or endoscopy; more than 12 ml/sec of urinary peak flow; and no recurrent urinary tract infections. Based on clinical success, patients were divided into two groups and compared. Clinical success was evaluated with particular regard to stent indwelling time and contracture etiology.

Results

The mean ± standard deviation age, stricture length, and indwelling time were 66.7 ± 9 years, 2.4 ± 1.4 cm, and 7.7 ± 2.2 months, respectively. Median (range) follow-up was 59 (8–73) months. The etiologies of BNC in this cohort were 57.1% retropubic radical prostatectomy; and 42.9% transurethral resection of prostate. Overall clinical success was achieved in 64.3% and the success rates did not differ by etiology. The success rates were 54.2% and 77.8% (P = 0.118) for retropubic radical prostatectomy and transurethral resection of prostate, respectively. Longer indwelling time (8–14 vs 3–7, months) was significantly associated with clinical success (78.3% vs 47.4%, P = 0.040).

Conclusion

Our data suggest that better clinical success was associated with longer indwelling time for stent in BNC treatment. In BNC management, Allium RPS treatment may be considered since its clinical efficacy is acceptable and tolerable.

Improving early urinary continence recovery after radical prostatectomy by applying a sutureless technique for maximal preservation of the intrapelvic urethra: A 17-year single-surgeon experience

BACKGROUND

There is a growing concern about postsurgical outcomes of radical prostatectomy, especially in the younger population and patients with earlier tumor stages. Here, we present our 17 years' experience of sutureless vesico-urethral alignment after radical prostatectomy with a focus on postoperative functional urinary outcomes.

METHODS

Data of 784 patients who underwent radical prostatectomy during 2001-2017 were evaluated retrospectively. Before surgery, patients' demographic information, pathologic stage, margin of surgery, prostate-specific antigen, and Gleason score were obtained. Then, serum prostate-specific antigen level, urinary continence, potency, and other functional outcomes of surgery were recorded after each postoperative visit.

RESULTS

The mean age (±standard deviation) of patients was 61.3 (±6.30) years. The median (IQ_25-75) duration of follow-up was 30 (12-72) months. Full continence was achieved in 90% and 95.9% of patients at 3 and 6 months post surgery and 96.4% of the patients were continent at the last follow-up visit. Bladder neck stricture occurred in 167 patients (21.3%). During the follow-up period, none of the patients complained of total incontinence and at the last visit, 36.6% of patients reported potency. The frequency of grade 2 continence was significantly higher in patients with high-stage tumors (T3/T4), high Gleason score (⩾8), high preoperative serum prostate-specific antigen (>20 ng/dL), and positive margin of surgery. Potency had a significant relationship with age, stage of the disease, and preoperative prostate-specific antigen.

CONCLUSION

Maximal sparing of intrapelvic urethral length through sutureless vesico-urethral alignment technique results in excellent early urinary continence recovery after radical prostatectomy. A more advanced tumor stage (T1/T2), a higher Gleason score, high preoperative prostate-specific antigen, as well as positive surgical margin are risk factors of postoperative incontinence in patients who undergo radical prostatectomy.

Vesicourethral Anastomotic Stenosis After Open or Robot-assisted Laparoscopic Retropubic Prostatectomy-Results from the Laparoscopic Prostatectomy Robot Open Trial

BACKGROUND

Vesicourethral anastomotic stenosis is a well-known late complication after open radical retropubic prostatectomy (RRP) with previously reported incidences of 2.7-15%. There are few reports of the incidence after robot-assisted laparoscopic radical prostatectomy (RALP) compared with RRP.

OBJECTIVE

The aim was to compare the risk of developing symptomatic stenosis after RRP and RALP, and to explore potential risk factors and the influence of stenosis on the risk of urinary incontinence.

DESIGN, SETTING, AND PARTICIPANTS

Between 2008 and 2011, 4003 men were included in a prospective trial comparing RRP and RALP at 14 Swedish centres. Clinical data and patient questionnaires were collected before, during, and after surgery.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Stenosis was identified by either patients' reports in questionnaires or case report forms. The primary endpoint is reported as unadjusted as well as adjusted relative risks (RRs), calculated with log-binomial regression models. Data on incontinence were analysed by means of a log-binomial regression model, with stenosis as an independent and incontinence as a dependent variable.

RESULTS AND LIMITATIONS

Symptomatic stenosis developed in 1.9% of 3706 evaluable men within 24 mo. The risk was 2.2 times higher after RRP than after RALP (RR 2.21, 95% confidence interval [CI] 1.38-3.53). Overall, urinary incontinence was twice as common in patients who had stenosis (RR 2.01, 95% CI 1.43-2.64).

CONCLUSIONS

This large prospective study found an overall low rate of vesicourethral anastomotic stenosis after radical prostatectomy, but the rate was significantly lower after robot-assisted prostatectomy. The risk of stenosis seems to be associated with the number of sutures/takes in the anastomosis, but this was statistically significant only in the RALP group.

PATIENT SUMMARY

We investigated the risk of developing vesicourethral anastomotic stenosis after open and robot-assisted radical prostatectomy. We found that the risk was generally lower than previously reported and lower after robot-assisted radical prostatectomy than after radical retropubic prostatectomy. Urinary incontinence was twice as common in patients with stenosis.

[Stricture of the vesicourethral anastomosis after radical prostatectomy]

BACKGROUND

The development of a stricture of the vesicourethral anastomosis is a serious complication after radical prostatectomy. Strictures occur in 5-8% of patients after radical prostatectomy.

SYMPTOMS

Usually the clinical symptoms include an irritative and obstructive component similar to benign prostatic hyperplasia. In rare cases, patients suffer from partial or complete stress incontinence as a result of the anastomotic stricture.

DIAGNOSTICS

The diagnostic workup is similar to the procedure for urethral strictures. In addition to uroflowmetry, a cystourethrogram (CUG) or, if necessary, a micturating cystourethrogram (MCU) can be performed. A urethrocystoscopy can be performed to ensure the diagnosis.

THERAPY

In most cases, endoscopic procedures were performed for treatment. Beside a transurethral dilation of the stricture or the Sachse urethrotomy, the most common procedure is transurethral resection to treat the stricture. However, all procedures are associated with a high recurrence rate. In recurrent strictures, open surgical procedures, usually a perineal reanastomosis, should performed early.

CONCLUSION

Endourological procedures like transurethral resection are a good treatment option, but due to the high recurrence rates, open surgical procedures should be discussed and if necessary should be performed early.

An update on best practice in the diagnosis and management of post-prostatectomy anastomotic strictures

Postprostatectomy vesicourethral anastomotic stenosis (VUAS) remains a challenging problem for both patient and urologist. Improved surgical techniques and perioperative identification and treatment of risk factors has led to a decline over the last several decades. High-level evidence to guide management is lacking, primarily relying on small retrospective studies and expert opinion. Endourologic therapies, including dilation and transurethral incision or resection with or without adjunct injection of scar modulators is considered first-line management. Recalcitrant VUAS requires surgical reconstruction of the vesicourethral anastomosis, and in poor surgical candidates, a chronic indwelling catheter or urinary diversion may be the only option. This review provides an update in the diagnosis and management of postprostatectomy VUAS.

Urethral Strictures and Stenoses Caused by Prostate Therapy

The number of patients with prostate cancer and benign prostatic hyperplasia is on the rise. As a result, the volume of prostate treatment and treatment-related complications is also increasing. Urethral strictures and stenoses are relatively common complications that require individualized management based on the length and location of the obstruction, and the patient's overall health, and goals of care. In general, less invasive options such as dilation and urethrotomy are preferred as first-line therapy, followed by more invasive substitution, flap, and anastomotic urethroplasty.

Comparison of continence outcomes of early catheter removal on postoperative day 2 and 4 after laparoscopic radical prostatectomy: a randomized controlled trial

BACKGROUND

The optimal timing of catheter removal following laparoscopic radical prostatectomy (LRP) has not yet been determined. This prospective study was designed to compare the efficacy and safety of catheter removal on postoperative day (POD) 2 versus POD 4 after LRP and its impact on urinary continence outcomes.

METHODS

One hundred and thirteen patients underwent LRP and were prospectively randomized into two groups: group 1 (n = 57) had the urinary catheter removed on POD 2 while group 2 (n = 56) had the catheter removed on POD 4. The urine loss ratio (ULR) was defined as the weight of urine loss in the pad divided by the daily micturition volume. Continence was defined as a pad-free status.

RESULTS

No significant differences were observed in clinical features between groups 1 and 2. Acute urinary retention (AUR) after catheter removal occurred in 21 patients (18.6%) (13 (22.8%) in group 1 and 8 (14.3%) in group 2 (p = 0.244). The first-day mean ULR values were 1.16 ± 4.95 in group 1 and 1.02 ± 3.27 in group 2 (p = 0.870). The last-day mean ULR values were 0.57 ± 1.60 in group 1 and 2.78 ± 15.49 in group 2 (p = 0.353). Continence rates at 3, 6, 9, and 12 months were 21.8, 41.1, 58.0, and 71.4% in group 1 and 34.5, 66.0, 79.2, and 83.7% in group 2 (p = 0.138, 0.009, 0.024, and 0.146, respectively). In AUR cases, continence rates at 3, 6, 9, and 12 months were 0, 23.1, 38.5, and 54.5% in group 1 and 37.5, 75.0, 87.5, and 87.5% in group 2 (p = 0.017, 0.020, 0.027, and 0.127, respectively). A multivariate analysis identified AUR after catheter removal on POD 2 as the only predictive factor for incontinence 6 and 9 months after LRP (p = 0.030 and 0.018, respectively).

CONCLUSIONS

Our results demonstrated that early catheter removal on POD 2 after LRP may increase the risk of incontinence.

TRIAL REGISTRATION

The study was registered as Clinical trial: (UMIN000014944); registration date: 12 March 2012.

Prevalence and risk factors of bladder neck contracture after radical prostatectomy

Purpose

To evaluate the prevalence of bladder neck contracture (BNC) and its risk factors in patients undergoing radical prostatectomy in Korea.

Materials and Methods

We analyzed data from 488 patients with prostatic cancer who underwent radical prostatectomy performed by seven surgeons in seven hospitals, including 365 open radical prostatectomies (ORPs), 99 laparoscopic radical prostatectomies (LRPs), and 24 robot-assisted laparoscopic radical prostatectomies (RARPs). Patients with BNCs were compared with those without BNCs to identify the risk factors for BNC occurrence.

Results

Overall, BNCs occurred in 21 of 488 patients (4.3%): 17 patients (4.7%) who underwent ORP, 4 patients (4%) who underwent LRP, and no patients who underwent RARP. In the univariate analysis, men with BNCs had a longer length of time before drain removal (12 days vs. 6.8 days, p<0.001), which reflected urinary leakage through the vesicourethral anastomosis. In the multivariate analysis, the length of time before drain removal was the only predictor of BNC (odds ratio, 1.12; p=0.001). Intraoperative blood loss was higher in patients with BNC, but the difference was not statistically significant.

Conclusions

The most significant factor related to BNC occurrence after radical prostatectomy in our study was the length of time before drain removal, which reflects urinary leakage from the vesicourethral anastomosis. The proper formation of a watertight anastomosis to decrease urinary leakage may help to reduce the occurrence of BNC.

[Anastomotic stricture following radical retropubic prostatectomy: insights into incidence, management and factors predisposing for occurrence]

PURPOSE

Anastomotic stricture (AS) following radical prostatectomy (RP) decreases patients' quality of life. It occurs in 0.5% to 32% of men after open radical retropubic prostatectomy (RRP), although its etiology is poorly understood. In a series of patients who received RRP, we analyzed the incidence, possible predisposing factors, and management of AS after RP.

MATERIALS & METHODS

Between April 1997 and March 2006, 129 consecutive patients underwent RRP in our hospital. Anastomosis between the bladder neck and urethra was performed with interrupted anastomosis using four 2-0 absorbable sutures. AS was diagnosed when a 16Fr. panendoscope could not be passed. We assessed the relationship between the management method for AS and time interval between the surgical procedure and diagnosis of the stricture. The relationships between comorbidities identified preoperatively (hypertension [HT], diabetes mellitus [DM], cardiovascular disease [CVD], cerebral infarction [CI] and smoking history) and the incidence of AS were determined. Risk factors, including age, body mass index [BMI], preoperative PSA, total prostate volume, operative time, blood loss, Foley duration, amount of stress urinary incontinence (SUI) per day, amount of drain output, pathological T stage, Gleason sum and surgical margin status were also assessed.

RESULTS

The rate of AS after RRP was 10.9% (14/129). In 10 patients (72%), AS occurred within 3 months of surgery, in 2 (14%) it occurred at 4-12 months after surgery and in 2 (14%) more than 12 months after surgery. In univariate and multivariate analyses, intraoperative bleeding of 1,800 ml or more was independently the strongest predictor of AS. In two patients a urethral bougie was used and 11 underwent internal urethrotomy. Only 1 patient underwent transurethral resection. Of the 8 patients whose strictures were diagnosed within 3 months after surgery and underwent internal urethrotomy, 6 had recurrent anastomotic strictures.

CONCLUSIONS

Risk factors for AS are thought to be multifactorial. Intraoperative blood loss was significantly associated with the development of anastomotic stricture. We should understand that anastomotic stricture following radical retropubic prostatectomy is not a rare morbidity and should inform patients about the possibility of postoperative AS.

Radical prostatectomy after previous transurethral resection of the prostate: robot-assisted laparoscopic versus open radical prostatectomy in a matched-pair analysis

PURPOSE

To determine whether previous transurethral resection of the prostate (TURP) compromises the surgical outcome and pathologic findings in patient who underwent either radical robot-assisted laparoscopic prostatectomy (RALP) or open retropubic radical prostatectomy (RRP) after TURP, because TURP is reported to complicate radical prostatectomy and there are conflicting data.

PATIENTS AND METHODS

From July 2008 to July 2010, 357 patients underwent RALP. Of these, 19 (5.3%) patients had undergone previous TURP. Operative and perioperative data of patients were compared with those of matched controls selected from a database of 616 post-RRP patients. Matching criteria were age, clinical stage, the level of preoperative prostate-specific-antigen, the biopsy Gleason score, the American Society of Anesthesiologists classification score, and prostate volume assessed during transrectal ultrasonography. All RRP and RALP procedures were performed by experienced surgeons.

RESULTS

Mean time to prostatectomy was 67.4 months in the RALP group and 53.1 months in the RRP group. Mean operative time was 217 ± 51.9 minutes for RALP and 174 ± 57.7 minutes for RRP (P<0.05). The overall positive surgical margin rate was 15.8% in both groups (pT(2) tumors: 10.5% for RALP and 5.3% for RRP; P=1.0). Mean estimated blood loss was 333 ± 144 mL in RALP patients and 1103 ± 636 mL in RRP patients (P<0.001). The difference between preoperative and postoperative hemoglobin levels was 3.22 ± 0.98 g/dL for RALP and 5.85 ± 1.95 g/dL for RRP (P=0.0002). The RALP and RRP groups also differed in terms of hospital stay (8.58 ± 1.17 vs 11.74 ± 5.22 days; P=0.0037), duration of catheterization (7.95 ± 5.69 vs 11.78 ± 6.97 days; P=0.0016), postoperative complications according to the Clavien classification system (6 vs 15 patients; P=0.0027), and transfusion rate (0% vs 10.5%; P<0.001).

CONCLUSION

RALP offers advantages over open radical prostatectomy after previous surgery. Although both techniques are associated with adequate surgical outcomes, RALP appeared to be preferable in our population of patients with previous prostate surgery.

Anastomotic stricture after minimally invasive radical prostatectomy: what should be expected from the Van Velthoven single-knot running suture?

BACKGROUND AND PURPOSE

Patients with localized prostate cancer (PCa) who are treated by radical prostatectomy (RP) have a good overall survival rate. Their quality of life, however, can deteriorate because of the incidence of bladder neck contracture (BNC). Our aim was to evaluate the incidence and the risk factors of BNC after minimally invasive radical prostatectomy (MIRP) with a single-knot running suture also known as the Van Velthoven technique (VVT).

PATIENTS AND METHODS

From 2003 to 2010, 2115 patients underwent extraperitoneal, transperitoneal, or robot-assisted RP for localized PCa. A single-knot running suture according to the VVT was performed for the vesicourethral anastomosis. Follow-up was scheduled and standardized for all patients and recorded into a prospective database. BNC was defined by a reduction of the lumen that does not allow the passage of an 18F fibroscope.

RESULTS

Mean follow-up of the patients was 43 (6-144) months. Of all, 1342, 241, and 532 had extraperitoneal, transperitoneal, and robot-assisted prostatectomy, respectively. BNC was diagnosed in 30 (1.4%) patients. Among them, 78% had the diagnosis within the first year of follow-up. Previous transurethral resection of the prostate (TURP) and external beam radiotherapy were independent risk factors of BNC.

CONCLUSIONS

BNC incidence after MIRP using the single-knot running suture for the vesicourethral anastomosis is low. Previous TURP and external beam radiotherapy are identified as risk factors. This technique showed satisfying results regardless of the classic laparoscopic or robot-assisted approach.

Post-radical-prostatectomy urinary incontinence: the management of concomitant bladder neck contracture

Urinary incontinence postradical prostatectomy is a common problem which adversely affects quality of life. Concomitant bladder neck contracture in the setting of postprostatectomy incontinence represents a challenging clinical problem. Postprostatectomy bladder neck contracture is frequently recurrent and makes surgical management of incontinence difficult. The aetiology of bladder neck contracture and what constitutes the optimum management strategy are controversial. Here we review the literature and also present our approach.

Radical retropubic prostatectomy: a review of outcomes and side-effects

BACKGROUND

Radical prostatectomy (RP) is worldwide probably the most common procedure to treat localized prostate cancer (PC). Due to a more widespread use of Prostate-Specific Antigen (PSA) testing, patients operated today are often younger and have organ confined disease justifying a more preservative surgery. At the same time, surgical technique has improved resulting in lower risk of permanent side-effects. This paper aims to give an overview of results from modern surgery regarding cancer control and side-effects. A brief overview of the history is given.

MATERIAL AND METHODS

A literature research identified recently published papers focusing on outcome and side-effects after RP.

RESULTS

One large randomized study (SPCG-4) compared RP and watchful waiting (WW). The study showed that RP was superior to WW in preventing local progression (RR = 0.36), distant metastasis (RR = 0.65) and death from PC (RR = 0.65). Observational studies also show a better outcome for men treated with RP compared to WW. Peri-operative mortality after RP is low in most material around 0.1%. The risk of stricture of the vesico-urethral anastomosis has decreased with improved technique from historically 10-20% to a low incidence of around 2-9% today. Also the risk of incontinence has declined with improved technique. However, while the rates of severe incontinence is usually very low, as many as 30% still report light incontinence after long-term follow-up. Erectile dysfunction (ED) is still a frequent side-effect after RP. This risk is dependent on age, pre-operative sexual function, surgical technique and other risk factors for ED such as smoking, diabetes, etc. In selected subgroups the risk of ED is low. Inguinal hernia is a more recently described complication after open retropubic RP with a postoperative incidence of 15-20% within three years of surgery.

CONCLUSION

RP is an effective method to achieve cancer control in selected patients. With modern technique it is a safe procedure with a low risk of permanent side-effects except for ED.

What is the long-term relevance of clinically detected postoperative anastomotic urine leakage after robotic-assisted laparoscopic prostatectomy?

OBJECTIVE

• To determine whether patients with postoperative clinically detected anastomotic urine leaks are at increased risk for poorer erectile function, urinary incontinence and bladder neck contracture (BNC) after robotic-assisted laparoscopic radical prostatectomy.

PATIENTS AND METHODS

• A retrospective review of all patients undergoing RALRP from October 2005 until December 2009 by a single surgeon (R.B.N.) was conducted. Clinically detected anastomotic urine leak was defined as drain output consistent with urine at more than 24 h postoperatively. The presence of BNC was identified on cystoscopy. • Erectile function was measured with the Sexual Healthy Inventory for Men (SHIM) questionnaire. Incontinence was measured by patient-reported daily pad use. • Univariate and multivariate analyses were performed. Outcomes were assessed at the most recent follow-up.

RESULTS

• Among 213 patients eligible for inclusion, 27 experienced an anastomotic urine leak (12.7%). • At a mean long-term follow-up of 24.2 months, there was no difference in SHIM scores (7.0 vs 13.1; P= 0.101), continence rates (87.5% vs 85.2%; P= 0.999) or risk of BNC (7.4% vs 3.2%; P= 0.268) between patients with and without postoperative anastomotic urine leaks, respectively. • The results did not change after controlling for covariates in a multivariate analysis.

CONCLUSION

• The present study suggests that patients with clinically detected postoperative anastomotic urine leaks do not necessarily have worse long-term outcomes of erectile function, continence and risk of BNC.

[Anastomotic stricture after radical prostatectomy for prostate cancer]

The present paper intends to review diagnosis and treatment issues of bladder neck anastomosis stricture after radical prostatectomy for localised prostate cancer. Even though cancer control is not necessarily a concern, quality of life may be greatly altered. Patients may suffer from dysuria, urgency and the feeling of incomplete bladder emptying. Flowmetry, cystoscopy and cystography contribute to its diagnosis. Treatment should be graded according to the severity of the disease and the quality of life of the patient. Cold-Knife incisions and pneumatic dilatation are the first line treatments. Holmium laser shows good results on the stricture in a second line treatment. A two-stage strategy with an endoluminal stent followed by artificial urinary sphincter implant is the ultimate option to manage severe strictures, while maintaining acceptable quality of life. Continence sparing is the challenge of the treatment of this type of stricture.

Single center comparison of anastomotic strictures after radical perineal and radical retropubic prostatectomy

OBJECTIVES

To analyze the incidence and management of anastomotic strictures (ASs) after radical perineal prostatectomy (RPP) and retropubic prostatectomy (RRP) and to identify possible predisposing factors.

METHODS

Between 1997 and 2007, we performed 866 RPP and 2052 RRP for localized prostate cancer. Median follow-up was 52 months (12-136). We analyzed preoperative serum prostate-specific antigen, prostate size, clinical and pathologic tumor stage, neoadjuvant hormone deprivation, previous transurethral resection of the prostate, transfusion requirement, anastomotic insufficiency, and acute urinary retention (AUR) and its subsequent management to identify possible predisposing factors for AS formation.

RESULTS

The rate of AS after RPP and RRP was 3.8% (33/863) and 5.5% (113/2048), respectively (P = .067). In multivariate analysis, RRP was a statistically significant risk factor for AS (P = .0002). On survival analysis, the incidence of AS was lower for RPP as compared with RRP at median follow-up (P = .0229). Primary response to endoscopic AS incision or resection was 94% (31/33) and 72.6% (82/113) after RPP and RRP, respectively. On multivariate logistic regression analysis biopsy Gleason score, previous transurethral resection of the prostate, prostate volume, pathologic tumor stage and grade, transfusion requirement, AUR, and surgical technique were independent risk factors for the development of AS. An AS developed in 45.4% (20/44) and 10.9% (5/46) of the postoperative AUR cases treated with a suprapubic cystostomy tube and a transurethral Foley catheter, respectively (P <.05).

CONCLUSIONS

ASs occur more frequently after RRP in comparison with RPP. Primary endoscopic AS incision or resection are both highly successful. Treating postoperative AUR with a suprapubic cystostomy poses a high risk for AS formation and should be avoided.

Endoscopic extraperitoneal radical prostatectomy after previous transurethral resection of prostate: oncologic and functional outcomes of 100 cases

OBJECTIVES

To study radical prostatectomy that has been reported to be more challenging and associated with complications in patients with history of transurethral resection of prostate (TURP).

METHODS

In our series, 100 of 2300 patients had undergone endoscopic extraperitoneal radical prostatectomy (EERPE) after previous TURP. All patients included in the study had at least 1-year follow-up. Patient demographics, mean blood loss, mean catheterization time, complications, functional and oncologic outcome were reviewed.

RESULTS

In all, 100 patients underwent EERPE and 26 of these patients were treated by nerve-sparing EERPE. Lymphadenectomy was performed in 45 patients. Operative time and mean blood loss were similar to previous EERPE series. The transfusion rate and mean time of catheterization were slightly higher than general EERPE population. Positive surgical margin rates were 7% for pT2 and 36% for pT3/4. At 12-month follow-up, 94% of the patients did not experience prostate-specific antigen level>or=0.1 ng/mL. The overall complication rate was 14%. At 12 months, 93% of patients were continent, 4% used 1-2 pads/day and 3% needed >2 pads/day. The potency rates for the 26 patients who underwent nerve-sparing EERPE were 52.6% and 66.7% at 6 and 12 months, respectively.

CONCLUSIONS

Patients who had previously undergone TURP should be considered for radical treatment with EERPE. The procedure is safe even though technically more demanding. Perioperative, functional, and short-term oncologic outcome is promising and directly comparable to existing EERPE experience. Potency results were lower in comparison with existing EERPE series.

Laparoscopic radical prostatectomy in clinical T1a and T1b prostate cancer: oncologic and functional outcomes--a matched-pair analysis

OBJECTIVES

To evaluate the effect of previous transurethral resection of the prostate (TURP) on surgical, functional, and oncologic outcomes after laparoscopic radical prostatectomy.

METHODS

From a series of 2100 patients undergoing laparoscopic radical prostatectomy, we compared the intraoperative complications and functional and oncologic outcomes for 55 patients who had been diagnosed with prostate carcinoma on previous TURP (group 1), with those of 55 matched patients who had not undergone previous prostate surgery (group 2). The patients were match-paired for age, operating surgeon, procedure type (eg, nerve-sparing, lymph node dissection), anastamotic technique, pathologic stage, and Gleason score. The minimal duration of follow-up was 24 months.

RESULTS

Both groups were similar with respect to patient age and pathologic stage. Of those with Stage cT1a and cT1b, 83.6% had a clinically significant tumor, with a mean tumor volume of 1.7 cm(3) for those with Stage cT1a and 2.4 cm(3) for those with Stage cT1b. The positive surgical margin rate was 14.5% and 16.3% for groups 1 and 2, respectively. Biochemical recurrence developed in 12.7% and 11% of patients in groups 1 and 2, respectively. Neither outcome was significantly different between the 2 groups. The long-term continence rates were similar; however, previous TURP was associated with a lower continence rate (49.1%) at 3 months compared with 61.8% for group 2 (P = .01). A nerve-sparing technique was used in 54% of group 1 patients. No significant difference was found in the potency rates between the 2 groups at 12 months.

CONCLUSIONS

Laparoscopic radical prostatectomy after TURP is a challenging, but oncologically safe, procedure. The interval to total continence was delayed, but the potency rates remain unchanged.

An analysis of the causes of bladder neck contracture after open and robot-assisted laparoscopic radical prostatectomy

OBJECTIVES

To evaluate the difference in outcome of bladder neck contracture (BNC) and its causes between large groups of patients undergoing open radical prostatectomy (ORP) and robot-assisted laparoscopic prostatectomy (RALP).

PATIENTS AND METHODS

We analysed 200 consecutive RPs performed by one surgeon for prostate cancer, 100 by ORP and 100 by RALP, between March 2003 and September 2007. The operative techniques of bladder neck repair and urethro-vesical anastomosis were different. The ORP patients had a conventional stomatization and 'racquet handle' repair of the bladder if necessary, with mucosal eversion and a direct circular interrupted 'end-to-end' suture anastomosis between the bladder and urethra. The RALP patients had no bladder neck reconstruction or mucosal eversion and their anastomosis was by the continuous suture 'parachute' technique.

RESULTS

There was no BNC in the RALP group, whilst 9% of the ORP group developed a BNC (P < 0.005). Apart from surgical technique, other variables, including patient age, previous transurethral resection of the prostate, Gleason score, T stage, urine infection rate, urinary leakage, blood loss, drain tube removal, anastomotic suture material, catheter type and catheter removal times were statistically comparable in both groups.

CONCLUSION

This series suggests that the major factor involved in the cause of bladder neck contracture after ORP, relates to the stomatization or 'racquet handle' bladder neck repair, and the end-to-end anastomosis between the urethra and stomatized bladder. Mucosal eversion might also contribute. Normal postoperative urinary leakage when the anastomotic apposition is good seems unlikely to be a significant aetiological factor in the development of BNC. Prolonged urinary leakage results from an anastomotic gap, which heals by second intention, thereby causing scarring and BNC. The RALP 'parachute' technique, which expands the anastomosis towards the bladder, appears to protect against BNC. Mucosal eversion is not necessary in the parachute repair.

Laparoscopic radical prostatectomy after transurethral resection of the prostate: surgical and functional outcomes

OBJECTIVES

To compare the morbidity and functional results after laparoscopic radical prostatectomy with and without previous transurethral resection of the prostate (TURP).

METHODS

From May 1998 to January 2005, 640 patients underwent laparoscopic radical prostatectomy, of whom 46 (7.2%) had previously undergone TURP. The perioperative and postoperative data were compared between group 1 (with previous TURP) and group 2 (without previous TURP). The functional results were assessed by self-administered questionnaires at 12 and 24 months after surgery.

RESULTS

In group 1, the operative time, hospital stay, and bladder catheterization duration was increased by 31 minutes, 1.9 days, and 2.9 days, respectively. The positive margin rate was not significantly different statistically between the two groups (P = .62). The 5-year actuarial freedom from biochemical recurrence rate was similar between the two groups (P = .86). Surgical complications occurred in 15.2% of group 1 and 5.7% of group 2 (P = .02). The risk of anastomotic stricture was 6.5% and 1.2% in groups 1 and 2, respectively (P = .02). Two years after surgery, the continence rate was 86.9% in group 1 and 95.8% in group 2 (P = .77), and the potency rate was 63.8% and 70.9%, respectively, after bilateral neurovascular bundle preservation (P = .61). However, neurovascular bundle preservation was performed after previous TURP in only 56.5% of group 1 vs 78.9% in group 2 (P = .02). The median follow-up was 50.8 months (range 30-107).

CONCLUSIONS

Laparoscopic radical prostatectomy can be performed after TURP without compromising the oncologic results. However, patients should be informed that the procedure is associated with worse intraoperative and postoperative outcomes. Although the urinary continence rate was not hampered by previous TURP, neurovascular bundle preservation is technically more difficult and compromises postoperative erectile function.

Post-operative drain output as a predictor of bladder neck contracture following radical prostatectomy

BACKGROUND

Bladder neck contracture (BNC) following prostatectomy has been reported in 0.5-32% of cases. While the etiology of a BNC is unclear, several factors have been associated with this complication, including blood loss, devascularization of bladder neck tissue, poor mucosal apposition and urinary extravasation. To study the impact of urinary extravasation on BNC formation, we used postoperative drain output as a surrogate measure for anastomotic leakage.

METHODS

All patients undergoing a radical retropubic prostatectomy (RRP) or a robotic assisted radical prostatectomy (RARP) from January 2000 to April 2006 have been entered into a prospective review board-approved database. All RRP patients had their anastomosis performed in an interrupted fashion using six monofilament 2-0 sutures. All robotic-assisted radical prostatectomy anastomoses were performed in a running fashion using 2-0 monofilament sutures. A single, closed suction Jackson Pratt drain was placed over the surgical bed at the conclusion of the case. Post-operative drain outputs were recorded. All patients were evaluated at 3, 6, 9, 12 and 24 months post-operatively. All patients who reported a diminished urinary stream or incontinence were evaluated by office cystoscopy. The inability to navigate an 18 French cystoscope through the bladder neck was defined as a bladder neck contracture.

RESULTS

A total of 576 patients underwent a radical prostatectomy over this time span. Complete records were available for 535 (93%) of these patients. There were 21 bladder neck contractures (3.9%) overall. The post-operative drain output ranged from 5-5,465 ml (median 119 ml). Eight patients who had drain outputs less than 119 ml developed a BNC while 13 BNC developed in patients with Jackson Pratt drain output > 119 ml (P = 0.343). In patients who underwent an open RRP, 19/424 (4.5%) developed contractures while 2/108 (1.9%) RARP patients developed a BNC (P = 0.105).

CONCLUSION

The amount of post-operative drain output is not statistically associated with the development of a bladder neck contracture.

Management of the complications of radical prostatectomy

Over the past several years, the morbidity associated with radical prostatectomy has improved due to advances in surgical technique, better understanding of male pelvic anatomy, and improved perioperative care. Despite these advances, patients are still at risk for several complications both intraoperatively and in the postoperative course. These risks include significant blood loss, rectal injury, ureteral injury, thromboembolic events, urinary incontinence, impotence, and a perioperative death rate of less than 1%. These risks should be reviewed and discussed before treating the patient with prostate cancer.

Bladder neck incision using a 70 W 2 micron continuous wave laser (RevoLix)

Postoperative bladder neck contracture continues to be a frequently occurring problem. Bladder neck incision (BNI) continues to be the standard mode of treatment. However, the recurrence rate appears to be high. Therefore alternative treatment options are still needed. We report about initial experience with the RevoLix 2 micron continuous wave laser for BNI after a 1-year follow-up. Fourteen patients with a second or third recurrence of bladder neck contracture after primary surgery were included into the trial. All patients reported high-grade obstruction and residual urine. BNI was performed using a 70 W 2-micron continuous wave laser (RevoLix). This laser utilizes the thulium as an active ion. Laser incisions were applied in 5 and 7o'clock lithotomy position. Remaining tissue was vaporized. Assessed outcomes were improvement in AUA-symptom-score, quality of life index and uroflowmetry, measured preoperatively, after 2 and 12 months postoperatively. Mean operating time was 7 min, mean catheterization time was 6.5 h. The mean maximum uroflow-rate improved from 9 ml/s preoperatively to 23 ml/s. AUA-symptom score improved from 22 to 8 points and quality of life index improved from four to one. Two patients developed restenosis so far. Although longer follow-up and larger sample size are needed, BNI with the RevoLix laser is a fast, safe and promising procedure in recurrent bladder neck sclerosis.

Vesicourethral Anastomosis During Radical Retropubic Prostatectomy: Does the Number of Sutures Matter?

OBJECTIVES

To prospectively evaluate the outcome of radical retropubic prostatectomy using three different techniques of vesicourethral anastomosis (VUA), with a different number of sutures used during this surgical step.

METHODS

Three groups of patients who had undergone nerve-sparing radical retropubic prostatectomy were compared. Overall, 90 patients with localized prostate cancer were recruited. The patients were randomly assigned to undergo one of three different VUA techniques. The anastomotic sutures consisted of four or six monocryl 2-0 stitches. The "two-suture" anastomosis in group 1 was performed by passing two U-shaped horizontal stitches at the 6-o'clock and 12-o'clock positions. The following intraoperative and perioperative parameters were considered for the comparative analysis: time to perform VUA, blood loss, hospitalization, and time to drain removal.

RESULTS

A statistically significant difference was found in terms of the mean time to anastomosis between groups 1 and 2 (3.61 +/- 1.14 versus 16.6 +/- 4.04, P <0.0001) and between groups 1 and 3 (3.61 +/- 1.14 versus 23.45 +/- 5.4, P <0.0001). No significant differences could be detected for blood loss, time to drain removal, or hospitalization. No significant difference was detected in terms of functional outcome (stricture rate, erectile function, and continence).

CONCLUSIONS

The number of stitches used for VUA during radical retropubic prostatectomy did not influence the perioperative and postoperative parameters. The time to VUA was considerably lower using our "two-suture" technique.

Previous bladder outlet surgery does not affect medium-term outcomes after laparoscopic radical prostatectomy

OBJECTIVES

To investigate the effect of previous bladder outlet surgery (BOS) on the peri-operative variables of patients having laparoscopic radical prostatectomy (LRP), as reported evidence as to whether BOS affects the outcome of RP is contradictory.

PATIENTS AND METHODS

Of 600 consecutive patients attending for LRP from March 2000 to January 2006, 558 had had no surgery (NS) and 42 (7.0%) had a history of BOS (transurethral prostatectomy in 35, 5.8%; bladder neck incision in seven, 1.2%). All patients had clinical stage < or = T3aN0M0 prostate cancer and had their procedure performed or supervised by the same surgeon.

RESULTS

Patients with previous BOS had a significantly greater age (mean 64.6 vs 61.8 years, P = 0.008), duration of catheterization (mean 13.7 vs 10.5 days, P = 0.003), proportion of pT3a tumours (16.7% vs 4.5%, P = 0.009) and potency rates at > or = 24 months (P < 0.001). Patients with previous BOS had a significantly lower body weight (mean 79.7 vs 83.0 kg, P = 0.05) and prostate weight (mean 46.7 vs 58.6 g, P = 0.01). Although patients with previous BOS had poorer continence at 3 months (61% vs 91%, P < 0.001), continence rates were similar in the two groups after this.

CONCLUSION

Previous BOS does not affect the medium-term outcomes after LRP.

Prostate cancer treatment and quality of life

Prostate cancer is detected today at earlier stages and in younger men than ever before. A lot of men are asymptomatic and also physically and sexually active at diagnosis, and most of them are being treated by curative procedures. These trends have led to increasing numbers of patients undergoing disease management for longer periods of time. For many patients quality of life (QoL) may be just as important as survival. Thus, QoL considerations may well be the critical factor in medical decision-making for most of them. Widespread interest in studying patient-centred outcomes has led to the development of methods for health-related QoL measurements. In fact, many questionnaires have been introduced in clinical practice to assess the impact of QoL in patients (SF-36, CARES, FACT, EORTC QLQ-C30, GRISS, UCLA PCI, PCOS). Herein we evaluate the impact of QoL on patients affected by prostate cancer and treated with watchful waiting, radical prostatectomy, radiotherapy and hormonal therapy; we have also considered the role of supportive care, including the administration of analgesics, antidepressants, corticosteroids, bisphosphonates, antiemetics and stool softeners, together with psychological support. The ultimate goal of QoL research should strongly improve medical care and concretely assist patients and physicians in treatment decision-making.

Nerve sparing open radical retropubic prostatectomy--does it have an impact on urinary continence?

PURPOSE

We prospectively assessed the role of nerve sparing surgery on urinary continence after open radical retropubic prostatectomy.

MATERIALS AND METHODS

We evaluated a consecutive series of 536 patients who underwent open radical retropubic prostatectomy with attempted bilateral, unilateral or no nerve sparing, as defined by the surgeon, without prior radiotherapy at a minimum followup of 1 year with documented assessment of urinary continence status. Because outlet obstruction may influence continence rates, its incidence and management was also evaluated.

RESULTS

One year after surgery 505 of 536 patients (94.2%) were continent, 27 (5%) had grade I stress incontinence and 4 (0.8%) had grade II stress incontinence. Incontinence was found in 1 of 75 (1.3%), 11 of 322 (3.4%) and 19 of 139 patients (13.7%) with attempted bilateral, attempted unilateral and without attempted nerve sparing, respectively. The proportional differences were highly significant, favoring a nerve sparing technique (p <0.0001). On multiple logistic regression analysis attempted nerve sparing was the only statistically significant factor influencing urinary continence after open radical retropubic prostatectomy (OR 4.77, 95% CI 2.18 to 10.44, p = 0.0001). Outlet obstruction at the anastomotic site in 33 of the 536 men (6.2%) developed at a median of 8 weeks (IQR 4 to 12) and was managed by dilation or an endoscopic procedure.

CONCLUSIONS

The incidence of incontinence after open radical retropubic prostatectomy is low and continence is highly associated with a nerve sparing technique. Therefore, nerve sparing should be attempted in all patients if the principles of oncological surgery are not compromised.

Urinary incontinence after radical prostatectomy: incidence by definition, risk factors and temporal trend in a large series with a long-term follow-up

OBJECTIVES

To investigate the incidence of urinary incontinence and its development over time, to compare the effects of alternative definitions on the incontinence rate and to explore risk factors for incontinence after radical retropubic prostatectomy (RRP) for clinically localized prostate cancer.

PATIENTS AND METHODS

Urinary continence was assessed using a questionnaire administered by a third party in 1144 consecutive patients after undergoing RRP at our department from January 1986 to December 2001. Overall, 985 men (86%) were suitable for evaluation (mean age 64.5 years, mean follow-up 95.5 months). We compared the effects of three definitions on the actuarial rate of continence: (1) no or occasional pad use; (2) 0 or 1 pads used daily, but for occasional dribbling only; (3) 0-1 pads daily. The time to recovery of continence was defined as the date on which the patient met the continence definitions. The impact of incontinence on health-related quality of life (HRQoL) was also evaluated. Univariate and multivariate analyses were used to identify predictors of incontinence, using data gathered prospectively.

RESULTS

At the last follow-up at 24 months after RRP, 83%, 92.3% and 93.4% of men achieved continence according to definitions 1, 2 and 3, respectively. The difference in time to recovering continence was significant for definition 1 compared to the others (P < 0.001). Most men using 1 pad/day complained of occasional dribbling only (89.3%), considered themselves continent (98%) and their HRQoL was not as seriously affected as those requiring > or = 2 pads/day. Men continent (by definition 3) at 2 years had an actuarial probability of preserving continence of 72.2% at the last follow-up. On multivariate analysis the age at surgery (P = 0.009), anastomotic stricture and follow-up interval (both P < 0.001) were independent prognostic factors. Bilateral neurovascular bundle resection was another independent predictive factor (P = 0.03) in the subset of the last 560 men with available data on surgical technique. The reduction in the incidence of incontinence over time was as high as 86%.

CONCLUSIONS

Continence improves progressively until 2 years from RRP but some patients can become incontinent later. The criterion of pad use discriminates well between men with a limited reduction in their QoL (no or one pad used) and those with a markedly affected QoL (> or =2 pads/day). It could be clinically valid to consider users of 1 pad/day as continent. Age, bilateral neurovascular bundle resection and anastomotic stricture are significant risk factors for incontinence. There was a marked trend for the incidence of incontinence and anastomotic stricture to decrease with time.

Factors predisposing to the development of anastomotic strictures in a single-surgeon series of radical retropubic prostatectomies

OBJECTIVE

To determine the rate of anastomotic stricture (AS) after radical retropubic prostatectomy (RRP) performed by one experienced surgeon, and to identify factors predisposing to its formation.

PATIENTS AND METHODS

In all, 708 men were prospectively monitored for the development of AS after RRP. Potential risk factors for AS were analysed.

RESULTS

There were no significant differences in age, Gleason score, nerve-sparing status, intraoperative blood loss, degree of extravasation on initial cystography, or duration of the indwelling urinary catheter between men who developed AS and men who did not. The mean postoperative blood loss was significantly higher in men who developed AS. The incidence of AS was also significantly higher in men whose bladder necks were reconstructed more narrowly.

CONCLUSION

The amount of bleeding and the calibre of the reconstructed bladder neck were significantly associated with AS formation after RRP. The development of a haematoma from bleeding might explain the increased likelihood of AS. The mechanism of AS formation is unrelated to the degree of urinary extravasation on cystography, providing that a urinary catheter is left indwelling until extravasation resolves.

What is the place of internal urethrotomy in the treatment of urethral stricture disease?

As a treatment for male urethral stricture, internal urethrotomy (IU) has the advantages of ease, simplicity, speed and short convalescence. Various modifications of the single cold-knife incision in the 12 o'clock position have been proposed, but there are no prospective, randomized studies to prove their claims of greater efficacy. IU can be performed as an outpatient procedure using local anesthesia, with an indwelling silicone catheter for 3 days after the procedure. Complications of IU are usually minor, including infection and hemorrhage. The reported success rate of IU varies, mainly because of differences in the definition of success and the duration of follow-up. Strictures can recur, usually within 3-12 months of IU. There are several known risk factors for recurrence: a previous IU, penile and membranous strictures, long (>2 cm) and multiple strictures, untreated perioperative urinary infection and extensive periurethral spongiofibrosis. Repeated IU might be useful in patients who have a stricture recurrence more than 6 months after the initial procedure, but repeat IU offers no long-term cure after a third IU, or if a stricture recurs within 3 months of the first IU. Such patients should be offered urethroplasty. Repeated IU followed by long-term self-dilation is an alternative option for men with severe comorbidity and limited life expectancy, or those who have failed previous urethroplasty. Overall, IU has a lower success rate (+/-60%) than urethroplasty (+/-80-90%), but if used for selected strictures, the success rate of IU could approach that of urethroplasty.

Bladder neck contracture after radical retropubic prostatectomy

OBJECTIVE

To examine the incidence, management and outcome of vesico-urethral anastomotic strictures after bladder-neck sparing radical retropubic prostatectomy (RRP).

PATIENTS AND METHODS

We assessed the incidence, management and outcome of anastomotic strictures in 510 consecutive patients (mean age 61 years, range 45-76) who had open RRP by one surgeon between 1994 and 2003.

RESULTS

The mean (range) follow-up was 30 (2-89) months; 48 patients (9.4%) developed an anastomotic stricture. Dilatation of the stricture was an effective treatment, with few patients requiring further treatment.

CONCLUSION

Stricture of the vesico-urethral anastomosis after bladder-neck sparing RRP is relatively frequent but can usually be successfully managed with one graduated dilatation under light sedation.

Fenestrated urethral catheter to aid anastomotic drainage after radical prostatectomy

A simple technique using a fenestrated urethral catheter to assist in drainage of pericatheter urethral exudates from the anastomosis of the urethra to the bladder neck in radical prostatectomy is described. It is applicable to open and laparoscopic techniques of radical prostatectomy.

Safety and outcome of early catheter removal after radical retropubic prostatectomy

OBJECTIVES

To assess the outcomes of patients who underwent radical retropubic prostatectomy (RRP) and had their indwelling urinary catheter removed on postoperative day 4 or later.

METHODS

The medical records of 342 consecutive patients undergoing RRP by a single surgeon were retrospectively reviewed. None of these patients had received radiotherapy, transurethral resection, or simple prostatectomy before RRP. The 342 patients were categorized into two groups according to the length of catheterization. Group 1 (n = 127) had the urethral catheter removed on postoperative day 4, and group 2 (n = 215) had the catheter removed later than postoperative day 4. Removal of the urinary catheter was only done if control cystography failed to demonstrate anastomotic extravasation. In the case of acute urinary retention, home care nurses and emergency room personnel reinserted the urinary catheter without cystoscopic assistance. Incontinence was rated according to the number of protective pads used in a 24-hour period as follow: none, mild (1 pad/day), moderate (more than 1 but 3 or fewer pads/day), and severe (more than 3 pads/day).

RESULTS

The mean age of the study population was 61.5 +/- 6.1 years. Acute urinary retention after catheter removal occurred in 11 patients (3%), 4 from group 1 and 7 from group 2. None of the patients requiring catheter reinsertion presented with complications related to this event. The overall continence rate was 58%, 85%, and 92% at 3, 9, and 12 months, respectively. The continence rates at 3, 9, and 12 months were higher for group 1 than for group 2 (P = 0.0002, P = 0.011, and P = 0.044, respectively). Bladder neck contracture was encountered in 14 patients (4%), 2 (2%) from group 1 and 12 (6%) from group 2. The only factor predicting continence was the duration of bladder catheterization.

CONCLUSIONS

Bladder catheters can be safely removed on postoperative day 4 in patients with normal cystograms after RRP. The continence and anastomotic stricture rates were improved in patients with 4 days of indwelling catheterization.

Early catheter removal after radical retropubic prostatectomy: long-term followup

PURPOSE

We examine the complication and continence rates with early catheter removal (day 3 or 4) after radical retropubic prostatectomy.

MATERIALS AND METHODS

A total of 365 patients with localized prostate cancer underwent radical retropubic prostatectomy at Indiana University Hospital with planned urethral catheter removal before discharge home. Low pressure cystograms were performed on postoperative day 3 or 4 to determine if catheter removal was possible. A subset of patients were analyzed using a validated prostate cancer specific questionnaire (University of California, Los Angeles Prostate Cancer Symptom Index) to determine quality of life outcomes.

RESULTS

The catheter was removed on postoperative day 3 or 4 in 263 patients (72%). The reasons for leaving the catheter indwelling were significant leak on cystogram or excessive suprapubic drainage (21%), extensive bladder neck reconstruction (1%) and prolonged hospitalization because of an ileus or other complicating factor (6%). Thirteen patients (3.6%) were either unable to void after catheter removal or presented with retention (not associated with hematuria or clots) after hospital discharge, requiring reinsertion of the Foley catheter. A total of 41 patients (11%) had either an early or late complication (excluding incontinence). There were 3 complications (0.8%) that were considered major because they were potentially life threatening or required a return to the operating room. A pelvic abscess developed in 2 patients and a lymphocele in 1, which required percutaneous drainage. After at least 6 months (mean 20.9 months) 140 patients (89.2%) and 14 (8.9%) reported excellent and good continence, respectively. The patient questionnaire demonstrated bother scores to be minimal to no bother for 95% to 98% of patients at 6 and 12 months.

CONCLUSIONS

This study confirms that it is safe to remove catheters in most patients 3 to 4 days after prostatectomy if a cystogram demonstrates no extravasation. Complication rates and continence rates with this approach compare favorably with series in which catheters are left indwelling for longer periods.

Relative advantages and disadvantages of radical perineal prostatectomy versus radical retropubic prostatectomy

In recent years prostate cancer has become the predominant malignancy in men. With the introduction of prostate specific antigen (PSA) the disease can be diagnosed at an early stage, at which surgical therapy can be curative. In the past century, the retropubic and the perineal routes were established as alternatives of surgical access to the gland for clinically localized prostate cancer. The selection of the operative route is mostly decided individually on the basis of surgical training and experience. The revived interest in perineal radical prostatectomy is explained by the fact that this technique has been associated with low morbidity. The differences of both surgical approaches of radical prostatectomy are elucidated and compared regarding tumor control and short and long term complication rates. Taking these results into consideration, specific advantages and disadvantages of radical perineal prostatectomy are emphasized.

New modality for treatment of resistant anastomotic strictures after radical prostatectomy: UroLume urethral stent

A new approach for the treatment of vesicourethral anastomotic stricture after radical retropubic prostatectomy is presented. The patient had failed treatment with bougies, balloon dilation, and cold-knife incision of the anastomotic area. Transurethral resection of the bladder neck resulted in a rapid recurrence of the stricture. He was successfully treated with insertion of a UroLume urethral stent. After 18 months of follow-up, the patient is symptom free.
