Do larger cuff sizes with artificial urinary sphincter placement increase the risk of leakage after placement?

INTRODUCTION: To determine whether larger artificial urinary sphincters (AUS) cuff sizes of ≥ 5.0 cm have an impact on urinary incontinence after AUS implantation as compared to cuff sizes ≤ 4.5 cm. MATERIALS AND METHODS: A retrospective chart review of AUS implants performed at our institution from 1991 to 2021. Medical records were reviewed for demographics including body mass index (BMI), cause of incontinence, pelvic radiation, valsalva leak point pressure (VLPP), degree of leakage preoperatively and at 1-year post-AUS surgery, AUS revisions, erosion rate and the need for adjunct medication postoperatively. RESULTS: A total of 110 patients were included in the analysis. Of these, 44 patients had an AUS cuff size of ≥ 5.0 cm and 66 patients had a cuff size ≤ 4.5 cm. After AUS implantation at 1 year both groups had a median pad use of 1 pad per day. Lastly, the erosion rate was higher in the ≤ 4.5 cm cuff group (7.7% vs. 2.4%) but this was not statically significant. In all cases (6 patients) of cuff erosion, each patient had been radiated. CONCLUSION: AUS cuff sizes of ≥ 5.0 cm do not appear to have a negative impact on the degree of incontinence at 1-year post AUS as compared to those with cuff sizes ≤ 4.5 cm. The erosion rate was higher in those with cuffs ≤ 4.5 cm but was not statistically significant. This would suggest that at AUS implantation, the surgeon should choose a larger cuff if there is any doubt especially in those with radiation.

Artificial urinary sphincter cuffs and safe instrument/catheter passage guidelines.

PURPOSE: The artificial urinary sphincter (AUS) is the gold standard for males with urinary incontinence. It is generally a safe procedure with a high degree of satisfaction. However, there is a lifelong risk of infection and erosion. AUS cuffs are commonly placed around the bulbar urethral area. There is always a risk of trauma and erosion of cuffs with catheterization or endoscopy. At this time, there is little guidance as to which size catheters or scopes can pass through each AUS cuff sizes safely. The goal of this study was to determine which size of catheters/scopes can pass through different cuff sizes safely in an ex vivo setting. METHOD: All AUS cuff sizes available (3.5 cm up to 6.0 cm), catheter sizes between 12 and 22 Fr, and scope sizes 19 Fr flexible/rigid, 21-26 Fr rigid scopes were examined. We used deflated assembled cuffs on the bench (ex vivo) and three different blind observers to measure the free space left between the wall of the cuff and the catheter/scope to be sure that there was consistency. We created a scale from 1 to 3 to determine the ease of passage for each catheter/scope. We also had an MRI radiologist examine bulbar urethra thickness in 20 male patients to determine the average thickness without the bulbospongiosus muscle. Using our average bulbar urethral thickness, we were able to estimate how much free space remained within the urethral lumen and how easy and safe it was to pass each catheter/scope. RESULTS: For 3.5 cm cuffs, 12 Fr catheters pass easily and safely, 14-16 Fr catheters and 19 Fr flexible/rigid scopes can pass through with some mild risk of trauma. Larger catheter/scope sizes cannot pass through without a significant risk of trauma. For 4.0 cm cuffs, 12-14 Fr catheters pass easily and safely. 16-18 Fr catheters and 19-21 Fr rigid/flexible scopes can pass with some mild risk of trauma. Larger catheter/scope sizes cannot pass through safely. For 4.5 cm cuffs, 12-18 Fr catheters and 19 Fr flexible/rigid scopes pass easily and safely. 20-22 Fr catheters and 21 Fr rigid scopes can pass with some mild risk of trauma. Larger catheter/scope sizes cannot pass through safely. For 5.0 cm cuffs, 12-22 Fr catheters and 19-21 Fr flexible/rigid scopes can pass easily and safely. 22-26 Fr scopes can pass with some mild risk of trauma. For 5.5 cm cuffs, all catheters/scopes can pass easily and safely. However, the 26 Fr rigid scope can pass with some mild risk of trauma. For 6 cm cuffs, all catheters/scopes examined can pass easily and safely. CONCLUSION: Our study can guide urologists in the management of patients with an AUS who need urethral catheters or endoscopy. These recommendations are based on the measurements of our study along with bulbar urethral thickness. In general, greater caution is needed with smaller cuff sizes (3.5-4.5 cm). Our recommendations, with minimal urethral compression, are purposely conservative and safe to avoid trauma and erosion of the AUS cuffs.

Is There an Association between Urinary Incontinence and Mortality? A Retrospective Cohort Study.

PURPOSE: Previous studies have shown an association between urinary incontinence and increased mortality independently of demographics and health status. However, they do not account for the effect of frailty as a state of vulnerability. We evaluated whether there is an association between urinary incontinence and mortality and, if so, whether adjustment for a frailty index would affect the association. MATERIALS AND METHODS: We performed a cross-sectional study in a nationally representative sample of 2,282 community dwelling individuals 50 years old or older who were surveyed between 2003 and 2006. The study primary outcome was overall survival as reported on December 31, 2011. We used design adjusted Cox proportional hazards regression models to estimate the hazard of mortality associated with urinary incontinence. We adjusted the models for demographics and a validated 45-item frailty index incorporating an accumulation of deficits in the domains of health and independence. RESULTS: Of the individuals 23% reported having urinary incontinence at least a few times per week. Stress urinary incontinence and urge urinary incontinence were associated with a 13.3% (95% CI 7.2-19.7) and 18.4% (95% CI 8.3-29.4) increase in the frailty index, respectively. Without controlling for frailty individuals with urinary incontinence were at higher risk for death (HR 1.39, 95% CI 1.13-1.72). When adjusted for the frailty index, the association between urinary incontinence and mortality was no longer significant (HR 1.10, 95% CI 0.89-1.36). CONCLUSIONS: The association between urinary incontinence and mortality can be understood based on increased frailty in incontinent individuals. Urinary incontinence itself is not independently associated with mortality. In clinical practice these findings underscore the importance of screening for frailty in addition to urinary incontinence.

Complications and Interventions in Patients with an Artificial Urinary Sphincter: Long-Term Results.

PURPOSE: The artificial urinary sphincter is a common treatment of male urinary incontinence. We sought to characterize long-term rates of artificial urinary sphincter revision/removal and reimplantation, and associated risk factors. MATERIALS AND METHODS: We performed a population based, retrospective study using the Ontario Health Insurance Plan database of all male patients who underwent artificial urinary sphincter implantation from 1994 to 2013. Hospital, diagnostic and billing codes were used to identify patients. The Kaplan-Meier method and multivariable Cox proportional hazards models were applied to examine the cumulative incidence of artificial urinary sphincter reimplantation and revision/removal, and identify risk factors, respectively. RESULTS: A total of 1,632 male patients underwent initial implantation of an artificial urinary sphincter. The 10-year revision/removal and reimplantation rates were 34% and 27%, respectively. There was no difference between high and low volume hospitals or between community and academic hospitals in terms of revision/removal. A high level of comorbidity was associated with an increasing risk of removal/revision. The reimplantation rate was significantly lower in patients who underwent insertion at hospitals with the highest volume of surgery (HR 0.55, 95% CI 0.37-0.82, p <0.01). A high level of comorbidity was not associated with an increasing risk of reimplantation. Preimplantation radiotherapy was not significantly associated with the risk of reimplantation (p = 0.17) or revision/removal (p = 0.95). Other factors were not significantly associated with reimplantation or revision/removal. CONCLUSIONS: Most men who undergo artificial urinary sphincter placement still have a device without repeat surgery 10 years following insertion. Radiotherapy does not increase the risk of repeat surgery. A high level of comorbidity was associated with an increasing risk of removal/revision.

Comparing a novel hand held device (Peritron+) to standard urodynamics in measuring intravesical pressure.

AIMS: Peritron+ is a new handheld device, which can be attached to a urethral catheter to measure intravesical pressures (Pves). The goal of this study was to assess if Pves recorded by standard urodynamics (UDs) are comparable to those recorded by the Peritron+. METHODS: Patients with voiding dysfunction and an indication for UD underwent measurement of Pves with nonvideo UD and Peritron+. Pves were recorded at volumes of 50, 100, and 200 mL for the supine and sitting positions. A failure of the Peritron+ was considered to be a discrepancy of Pves values >3 cmH2 O between Peritron+ and UD recordings. Two-way ANOVA was used to assess for statistical significance. P-values < 0.05 were considered significant. RESULTS: Ten female patients, mean age 51 years old, were enrolled in the study. The difference in Pves measurements between Peritron+ and UD were ≤3 cmH2 O at all bladder volumes measured in a supine and sitting positions. There were no adverse events and there were no malfunctions of the Peritron+ device during the study. CONCLUSIONS: Peritron+ handheld device accurately assessed Pves at different intravesical volumes when compared to UD measurements. The Peritron+ is a simple and safe device, which can be used in the office by a clinician and at home by a patient to monitor Pves and help to select patients who may require standard UD re-evaluation. This will be a valuable tool in managing patients with neurogenic and nonneurogenic bladders who are at a risk of upper urinary tract deterioration.

Gender differences in overactive bladder.

Overactive bladder (OAB) is a common condition in both women and men. Although prevalence's are similar in both genders, sex specific differences do exist in relation to individual OAB symptoms as well as degree of bother and quality of life. The added effect of prostatic enlargement in men leads to slightly different evaluation and treatment regimens in both genders. This review will examine the gender differences in OAB related to epidemiology, OAB evaluation, investigation and treatment. This information will assist the primary care physician in assessing and initiating treatment in patients with OAB. It will further the understanding of the spectrum of treatments available for OAB and assist in determining the appropriateness and timing of referral of such patients to a urologist.

Success rates of patients with poor emptying on clean intermittent catheterization.

INTRODUCTION: Clean intermittent catheterization (CIC) theoretically reduces incontinence, urinary tract infections (UTIs) and lower urinary tract symptoms (LUTS) in the face of poor emptying. It is unclear whether all patients realize these benefits or if CIC is only helpful for some. MATERIALS AND METHODS: A retrospective review of 321 patients all of whom underwent urodynamic study prior to starting CIC for impaired emptying. Success was considered to be no incontinence, no UTIs, and no LUTS while performing CIC. Patients who did not meet these criteria or who stopped CIC for whatever reason were classified as failures. RESULTS: The mean duration of follow up was 4.3 years (+/- 4.4 years). Overall 51% of the cohort was classified as a success. Among those patients started on CIC to treat incontinence, recurrent UTIs or LUTS the success rate was 43%. We identified the comorbidity of diabetes mellitus, the use of anticholinergic medications, the need for a homecare nurse to perform the CIC, and a post-void residual (PVR) of <300 cc at initial urodynamics to be independently associated with failure on CIC. CONCLUSIONS: CIC resolved incontinence, recurrent UTIs, and LUTS in some but not all patients with impaired emptying. We identified characteristics associated with failure on CIC. Our study has provided some direction as to those individuals most and least likely to benefit from adopting this mode of bladder management for poor emptying.

Medical management of overactive bladder.

Overactive bladder (OAB) with or without urinary incontinence is a common condition in both men and women. OAB has a significant impact on quality of life for most patients. In most cases, sophisticated testing is not required for a primary care physician to diagnose OAB and start treating a patient. Management of OAB requires behavioral modification and, if necessary, pharmacotherapy may be added. If a patient does not respond to treatment initiated by a primary care physician, then he or she should be referred to a specialist in OAB to undergo further investigations and treatments.

Results of high intensity focused ultrasound treatment of prostate cancer: early Canadian experience at a single center.

INTRODUCTION: High intensity focused ultrasound (HIFU) is a non-invasive technique that uses focused ultrasound waves to ablate tissue. This retrospective study evaluates the early HIFU experience at a single Canadian center. MATERIALS AND METHODS: Ninety-five patients were treated between March 2006 and December 2007 using the Sonablate-500 device (Focus Surgery, Indianapolis, IN, USA). Follow up occurred at 3 month intervals and included serial prostate-specific antigen (PSA) measurements, assessments of erectile function and continence rates with the international index of erectile function (IIEF) and expanded prostate cancer index composite (EPIC) questionnaires respectively. Early and late complications were also studied. RESULTS: There were 95 patients treated by five urologists. The mean age of patients was 64 years (range 46-91). The majority of men treated had Gleason 6 (n = 53) or Gleason 7 (n = 35) disease. The remainder had Gleason 8 (n = 5) and Gleason 9 (n = 2) prostate cancer. Prostate volume in the pre-treatment group was 30.5 cc (range 14.4 cc-73 cc). Cytoreductive androgen deprivation therapy prior to treatment was administered to 10 men. Post-HIFU with a minimum 6 months follow up (mean 10.62 months), 2% (1/59) of men had de novo moderate to severe erectile dysfunction (IIEF ≤ 11). With a minimum of 6 months follow up (mean 8.85 months), 17% (7/41) of the men had significant incontinence according to their EPIC scores. Early complications included catheter-related problems (n = 10), retention (n = 16), and urosepsis (n = 1). Late complications included need for cystoscopy (n = 25), TURP (n = 6), VIU/dilatation for stricture or bladder neck contracture (n = 13) and self-catheterization (n = 1). Prostatorectal fistula occurred in one patient who had prior radiotherapy. Salvage HIFU following radiation failure was performed in seven men. Recurrence of cancer following HIFU was diagnosed in seven men. Salvage treatment included radical prostatectomy (n = 3), radiation therapy (n = 2), repeat HIFU (n = 1), hormone therapy (n = 1). CONCLUSIONS: In our early experience HIFU treatment for prostate cancer was associated with a moderate rate of complications and failure. Further studies are required to examine long term outcomes with HIFU.

Assessment of urinary tract calculi with 64-MDCT: The axial versus coronal plane.

OBJECTIVE: The objective of our study was to compare the detection rate, conspicuity, and size measurements of urinary tract calculi on coronal reformations versus the axial plane using 64-MDCT. MATERIALS AND METHODS: For this retrospective study, 80 consecutive CT examinations performed for clinical diagnosis of renal colic or for the assessment of known nephrolithiasis were evaluated. All studies were stripped of patient identifiers, and the axial and coronal plane images of each study were randomized and presented to two abdominal radiologists. For each study, the radiologists recorded the number and location of stones, diagnostic confidence and stone conspicuity (subjectively on a 2-point scale), and stone size. The standard of reference was data from a consensus reading with the study coordinator examining the same parameters on images in both planes of each patient. Detection rates were compared between planes using logistic regression with generalized estimating equations to account for multiple stones per patient. RESULTS: On consensus reading, 272 stones were identified. For all renal stones, the coronal plane detected more stones as compared with the axial plane (p < 0.001). For stones smaller than 5 mm, a higher proportion received the maximal conspicuity score on the coronal plane than on the axial plane (p < 0.001). Both reviewers better estimated stone size on the coronal plane than the axial plane (p = 0.02); their axial plane measurements underestimated stone size by 13.4% (mean). CONCLUSION: The detection of stones and estimation of maximal stone diameter were improved using coronal reformations. The conspicuity of stones and diagnostic confidence in identifying stones smaller than 5 mm in diameter were also improved on the coronal plane.

Complications after surgery for benign prostatic enlargement: a population-based cohort study in Ontario, Canada.

OBJECTIVES: To examine the complication rates after benign prostatic enlargement (BPE) surgery and the effects of age, comorbidity and preoperative medical therapy. DESIGN: A retrospective, population-based cohort study using linked administrative data. SETTING: Ontario, Canada. PARTICIPANTS: 52 162 men≥66 years undergoing first BPE surgery between 1 January 2003 to 31 December 2014. INTERVENTION: Medical therapy preoperatively and surgery for BPE. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was overall 30-day postoperative complication rates. Secondary outcomes included BPE-specific event rates (bleeding, infection, obstruction, trauma) and non-BPE specific event rates (cardiovascular, pulmonary, thromboembolic and renal). Multivariable analysis examined the association between preoperative medical therapy and postoperative complication rates. RESULTS: The 30-day overall complication rate after BPE surgery was 2828 events/10 000 procedures and increased annually over the study period. Receipt of preoperative α-blocker monotherapy (relative rate (RR) 1.05; 95% CI 1.00 to 1.09; p=0.033) and antithrombotic medications (RR 1.27; 95% CI 1.22 to 1.31; p<0.0001) was associated with increased complication rates. Among the ≥80-year-old group, the rate of complications increased by 39% from 2003 to 2014 (RR 1.39; 95% CI 1.21 to 1.61; p<0.0001). The mean duration of medical and conservative management increased by a mean of 2.1 years between 2007 and 2014 (p<0.0001 for trend). CONCLUSIONS: Thirty-day complication rates after BPE surgery have increased annually between 2003 and 2014. Preoperative medical therapy with alpha blockers or antithrombotics was independently associated with higher rates of complications. Over this time, the duration of conservative therapy also increased.

Durability of endourologic skills: two-year follow-up study.

PURPOSE: To assess the long-term durability of endourologic skills among urology trainees after an intensive technical skills training course. SUBJECTS AND METHODS: Seventeen urology residents participated in a 2-day ureteroscopy course at a surgical skills center. Residents performed rigid ureteroscopy and basket manipulation of a small midureteral stone. Performance was assessed immediately after the course and 1 year and 2 years after training. Residents prospectively tracked all ureteroscopic cases in which they were considered the primary surgeon (i.e., performed greater than 75% of the procedure). Performance was measured using a validated global rating score (GRS), checklist score (CLS), and time required to complete the task. RESULTS: Overall, GRS improved over the 2-year follow-up (P < 0.001), with most of the improvement occurring in the first year (P = 0.03). The CLS and time to complete the task did not change (P = 0.08 and 0.12, respectively). At the 2-year follow-up, the number of cases logged had no significant effect on performance. CONCLUSIONS: Ureteroscopy skills are retained and continue to improve 2 years after completing an intense training session that uses high-fidelity bench models. Ureteroscopic experience is important for the maintenance and development of skills, even though they appear to plateau after 1 year. This result may also reflect a ceiling effect of the assessment tools.

Review of the epidemiology of overactive bladder.

Overactive bladder (OAB) is common in both men and women. It is a symptom complex that causes significant detriment to quality of life in patients. Although the prevalence of OAB is similar in both sexes, there are sex-specific differences in individual symptoms and the impact on quality of life. The coexistence of benign prostatic hyperplasia with OAB can worsen quality of life in men. This review examines the major studies that looked at the epidemiology of OAB as it relates to both sexes. It focuses on both the overall prevalence rates and the incidence of individual symptoms. This paper also addresses the level of bother and quality of life in men and women with OAB. In addition, the relationship between OAB and benign prostatic hyperplasia is reviewed.

Artificial urinary sphincter erosion after radical prostatectomy in patients treated with and without radiation.

INTRODUCTION: There has been increasing evidence supporting the use of adjuvant radiotherapy after radical prostatectomy (RP) for prostate cancer. Significant stress incontinence after RP is not uncommon and the artificial urinary sphincter (AUS) is the gold standard of treatment. Our objective was to assess if increased use of radiotherapy after RP has changed the rate of erosion and infection in the face of improvement in radiation technique and equipment in men who had an AUS implanted in the last 10 years. METHODS: We retrospectively examined 118 patients from December 2001 to January 2012 who underwent a RP with or without postoperative radiotherapy and subsequently had an AUS implanted. We divided the patients into two cohorts (Group 1: December 2001-December 2006 and Group 2: January 2007-January 2012). We reviewed all patient records for age, cuff size implanted, history of postoperative radiotherapy, previous incontinence surgery, revisions, and complications (erosion/infection). RESULTS: There were 36 and 82 patients in Groups 1 and 2, respectively. The mean age was similar between groups, 67 years both groups (p = 0.980). The number of patients treated with postoperative radiotherapy was similar between groups (36% vs. 32%, p = 0.640, respectively). There was no difference in the incidence of erosion or infection between Group 1 and 2 (p = 0.848 and p = 0.178, respectively). The overall relative risk (RR) of erosion was significantly higher in those who had radiotherapy compared to those who did not (RR 4.05, 95% confidence interval 1.1-15.3). CONCLUSIONS: Over the last 10 years, there has not been an increase in the number of patients receiving an AUS after RP and radiotherapy at our centre. During this time, the incidence of erosion and infection has not increased. However, our study reaffirms that the relative risk of erosion remains higher in patients who have had radiotherapy despite improvement in radiation treatment techniques and equipment.

Preliminary evaluation of a new controlled-release oxybutynin in urinary incontinence.

OBJECTIVE: To conduct a preliminary evaluation of a new oral formulation of controlled-release (CR) oxybutynin tablet taken once-daily in patients with urinary urge incontinence. RESEARCH DESIGN AND METHODS: A single-centre, open-label, 8-week study was conducted. Patients with urodynamically-confirmed detrusor instability, micturition frequency (>/= 8 voids/day) and/or urinary incontinence (>/= 2 incontinence periods/day) were enrolled. The study duration was 8 weeks: patients received IR oxybutynin (2.5-5 mg bid) for 2 weeks, followed by a 2-week washout/baseline period to avoid carryover effects, and oral CR oxybutynin (15 mg OD) for 4 weeks. Daily void frequency, fluid intake, urinary incontinence episodes, and spontaneously reported adverse events were recorded in a daily diary for five consecutive days in each treatment period. RESULTS: Of 12 enrolled patients, 9 patients efficacy; all patients were evaluable for safety. completed the study and were evaluable for Compared to baseline/washout, CR oxybutynin reduced UI episodes/day by 45% (p = 0.13) and micturitions/day by 15% (p = 0.07). Treatment with IR oxybutynin (mean dose: 6.7 +/- 2.5 mg/day) reduced UI episodes/day from baseline by 7% (p = 0.58) and voids/day by 6% (p = 0.29). Fluid intake remained consistent at approximately 2 litres/day during all study periods. The most common adverse event was dry mouth. CONCLUSIONS: Based on the reductions in daily frequency of incontinence and micturition following 4-weeks treatment, CR oxybutynin (15 mg OD) was at least as effective as the patients' previous dose of IR oxybutynin (mean dose: 6.7 +/- 2.5 mg/day). These improvements were achieved without restriction of fluid intake. Initial 15 mg doses of CR oxybutynin appear to be well tolerated.

Success of sildenafil for erectile dysfunction in men treated with brachytherapy or external beam radiation for prostate cancer.

PURPOSE: We undertook to determine if any significant differences in the efficacy of sildenafil citrate for erectile dysfunction (ED) exists between patients who have received external beam radiation or brachytherapy for prostate cancer. MATERIALS AND METHODS: Thirty-one patients who had received external beam radiation and nineteen patients who had received brachytherapy for prostate cancer and were subsequently treated with sildenafil citrate for post-irradiation ED comprised the patient population. A chart analysis was performed to determine either the presence or absence of concomitant risk factors for ED (coronary artery disease, diabetes, hypertension and smoking history) as well as age at radiation and time lapse between radiation completion and sildenafil citrate administration. Patients were then contacted to ascertain sildenafil citrate efficacy (defined as the continued use of sildenafil citrate), dosage used and medication tolerance. RESULTS: Continued use of sildenafil citrate was reported by 12/19 (63%) of the brachytherapy patients and 7/31 (22%) of the external beam radiation patients, a significant difference (P<0.007). Of those with continued use of sildenafil citrate, the patients who had undergone external beam radiation had a longer mean period of use (33.7 months) than those who had been treated with brachytherapy (14.3 months) (P=0.006). The mean elapsed time between completion of radiation and administration of sildenafil citrate was 7.6 months and 21.6 months for the brachytherapy and external beam radiation patients respectively (P=0.002). A significant difference in mean age existed between the patient groups, with the external beam radiation group being significantly older (69.8 years and 65.1 years respectively, P=0.007) at the time of sildenafil citrate administration. Of the risk factors for ED examined in each patient group, none were found to predict treatment failure with sildenafil citrate. Of the patients who did not experience success with sildenafil citrate, both groups used the medication for comparable periods of time. CONCLUSIONS: Sildenafil citrate improved ED in a significantly greater number of patients who had undergone brachytherapy over those who had received external beam radiation. However, the patients who had received external beam radiation were both older and experienced a longer lapse of time between completion of radiotherapy and administration of sildenafil citrate than the brachytherapy patient group. This may explain the poorer success in the external beam radiation patients. The success of sildenafil in both groups of patients was lower than has previously been reported.

Update on medical therapy for male LUTS.

The medical management of lower urinary tract symptoms (LUTS) is aimed at addressing voiding and storage symptoms in patients with benign prostate hyperplasia (BPH) symptoms with or without an over-active bladder (OAB). Current available options for BPH include alpha-blockers, 5-alpha reductase inhibitors and phosphodiesterase type 5 inhibitors. For OAB, options include antimuscarinics, with or without an alpha-blocker, the beta-3-adrenergic agonist mirabegron and the synthetic diuretic desmopressin. With the availability of numerous options and combinations available for the treatment of LUTS, individual patient assessment is the key to optimal symptom control and management of adverse effects.

Do patients know their nerve-sparing status after radical prostatectomy?

OBJECTIVE: To determine patients' knowledge regarding their nerve-sparing status (NSS) after radical prostatectomy (RP) and what factors during their clinical treatment are associated with this. METHODS: One hundred consecutive patients attending an erectile dysfunction clinic in Toronto, Canada, with a prior RP were surveyed from December 2010 to June 2011. Patients were questioned whether they had undergone a nerve-sparing procedure and, if so, whether it was unilateral or bilateral. Patients were assessed on both knowledge (known vs unknown) and accuracy (correct vs incorrect) regarding their NSS. Operative reports were used to determine the true NSS of each patient. RESULTS: Thirty-nine percent of patients had no knowledge of their NSS. Forty-five percent of patients were able to correctly identify their NSS, including only 19% of patients undergoing a non-nerve-sparing procedure. On univariate analysis, factors associated with patients correctly knowing their NSS were age, having a nerve-sparing strategy dictated in the preoperative clinic note, nerve sparing included in the surgical consent form, and type of nerve-sparing procedure performed. On multivariate analysis, planned nerve-sparing approach dictated in the preoperative note (odds ratio [OR], 4.86), nerve sparing included in surgical consent (OR, 3.76), time since surgery (OR, 0.99), and having a bilateral nerve-sparing procedure (OR, 5.91) were associated with correctly identifying one's NSS. CONCLUSION: After RP, a significant proportion of patients with erectile dysfunction have no knowledge of whether they underwent a nerve-sparing procedure. By discussing with patients the planned nerve-sparing technique preoperatively and counseling them on their NSS postoperatively, urologists may be able to improve on patient recollection of their NSS.

Long-term complications in men who have early or late radiotherapy after radical prostatectomy.

INTRODUCTION: Choosing adjuvant radiotherapy (RT) or salvage RT after radical prostatectomy (RP) for locally advanced prostate cancer is controversial. Performing RT early after RP may increase the risk of urinary complications compared to RT performed later. We evaluated the urinary complication rates of men treated with surgery followed by early or late RT. METHODS: Using a retrospective chart review, we compared rates of urinary incontinence (UI), bladder neck contracture (BNC), or urethral stricture in men with prostate cancer treated with early RT (<6 months after RP) or late RT (≥6 months after RP), 3 years after RT. RESULTS: In total, 652 patients (between 2000 and 2007) underwent early RT (162, 24.8%) or late RT (490, 75.2%) after RP. The mean time to early RT was 3.6 months (range: 1-5 months) and to late RT was 30.1 months (range: 6-171 months). At 3 years post-RT, UI rates were similar in the early RT and the late RT groups (24.5% vs. 23.3%, respectively, p = 0.79). Prior to RT, 27/652 (4%) patients had a BNC and 11/652 (1.7%) had a urethral stricture, of which only 1 BNC persisted at 3 years post-RT. After RT, 17/652 (2.6%) BNC and 4/652 (0.6%) urethral stricture developed; of these, 6 BNC and 2 urethral strictures persisted at 3 years. CONCLUSION: Rates of UI, BNC, and urethral stricture were similar with early and late RT at 3 years post-RT. These findings suggest that the timing of RT after RP does not alter the incidences of these urinary complications and can aid in the decision-making process regarding adjuvant RT versus salvage RT.
