[PMID: 38193218 DOI: 10.4081/aiua.2023.12138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 11/30/2023] [Indexed: 01/10/2024] Open
Abstract
INTRODUCTION The post-prostatectomy incontinence is influenced by multiple elements, anatomic components and biological factors. The bladder neck preservation, more accurate during robot assisted radical prostatectomy, works on two anatomic components responsible for post-prostatectomy continence. The bladder neck preservation spares the internal sphincter, which is responsible for passive continence, and results in earlier return to continence and lower rates of post-prostatectomy incontinence. Moreover, this surgical technique spares the zone of urothelium coaptation and provides primary resistance to the urine to maintain postprostatectomy continence. The potential risk of bladder neck positive surgical margins (PSM) may prevent the usage of the bladder neck preservation. AIM The purpose of this study is to evaluate the surgical and pathological outcome in prostate cancer patients underwent robot assisted radical prostatectomy with bladder neck preservation. MATERIALS AND METHODS Prospectively, we have collected demographic, clinical, surgical and pathological data of prostate cancer patients underwent robot assisted radical prostatectomy with bladder neck preservation, from January 2014 to December 2016, in Urological Clinic of the University of Padua. Moreover, it was valued the presence of alterations or continuous solutions of specimen external capsule, attributable to the surgical technique of bladder neck preservation, by microscopic and macroscopic pathological analysis. RESULTS According to D'Amico risk classification, 40 patients (45.4%) had a low risk neoplasia, 35 patients (39.8%) had an intermediate risk neoplasia, 13 patients (14.8%) had an high risk neoplasia. The median prostatic volume, valued on specimen, was 30.84 cc (21.5-44.75 cc). The median prostatic weight, valued on specimen, was 51 gr (36-67 gr). The pathological stage of disease was pT2a in 11 cases (12.5%), pT2b in 37 cases (42.1%), pT3a in 28 cases (31.8%), pT3b in 12 cases (13.6%). The pathological stage of lymph node involvement was pNx in 17 cases (19.3%), pN0 in 66 cases (75%), pN1 in 5 cases (5.7%). The prostate cancers diagnosed had a Gleason score at specimen of 6 in 10 cases (10.4%), 7 (3+4) in 30 cases (34.1%), 7 (4+3) in 20 cases (22.7%), 8 in 19 cases (21.6%) and 9 in 9 cases (10.2%). The prostatic base was involved by neoplasia in 14 patients (15.9%); of these, 5 patients (35.7%) had bladder neck PSM. The patients with bladder neck PSM had: a pathological stage of disease as pT3a in 2 cases (40%) and pT3b in 3 cases (60%); a pathological stage of lymph node involvement as pN0 in 2 cases (40%) and pN1 in 3 cases (60%); a Gleason score at specimen of 8 in 3 cases (60%) and 9 in 2 cases (40%); multiple PSM. Nobody had alterations or continuous solutions of specimen external capsule, attributable to surgical technique of bladder neck preservation. CONCLUSIONS The bladder neck preservation, during robot assisted radical prostatectomy, is a safe oncological procedure resulting in a good functional outcome, about post-prostatectomy continence, working on two anatomic components responsible for post-prostatectomy continence. The bladder neck PSM are linked to neoplasia with adverse pathological features, rather than the bladder neck preservation.

Abstract
PURPOSE To report the prevalence of the definitions used to identify post-prostatectomy incontinence (PPI) after laparoscopic radical prostatectomy (LRP), and to compare the rates of PPI over time under different criteria. MATERIALS AND METHODS In the period from January 1, 2000, until December 31, 2017, we used a recently described methodology to perform evidence acquisition called reverse systematic review (RSR). The continence definition and rates were evaluated and compared at 1, 3, 6, 12, and >18 months post-operative. Moreover, the RSR showed the "natural history" of PPI after LRP. RESULTS We identified 353 review articles in the systematized search, 137 studies about PPI were selected for data collection, and finally were included 203 reports (nr) with 51.436 patients. The most used criterion of continence was No pad (nr=121; 59.6%), the second one was Safety pad (nr=57; 28.1%). A statistically significant difference between continence criteria was identified only at >18 months (p=0.044). From 2013 until the end of our analysis, the Safety pad and Others became the most reported. CONCLUSION RSR revealed the "natural history" of PPI after the LRP technique, and showed that through time the Safety pad concept was mainly used. However, paradoxically, we demonstrated that the two most utilized criteria, Safety pad and No pad, had similar PPI outcomes. Further effort should be made to standardize the PPI denomination to evaluate, compare and discuss the urinary post-operatory function.

The effects of bladder neck sparing with an additional anterior urethral fixation on postoperative continence after robot-assisted radical prostatectomy. North Clin Istanb 2021; 8:57-62. [PMID: 33623874 PMCID: PMC7881433 DOI: 10.14744/nci.2020.00533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Accepted: 08/27/2020] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE: Urinary incontinence remains one of the main problems affecting the quality of life after radical prostatectomy. Along with the improved understanding of the precise anatomy of the prostate, urethra and their surrounding structures, minimally invasive surgical techniques have been refined and described, aiming to improve functional outcomes without oncological compromise. This study aimed to investigate the impacts of anterior urethral fixation (AUF) and bladder neck sparing (BNS) on the early continence success after Robot-assisted Radical Prostatectomy (RALP). METHODS: This retrospective study included 120 patients who underwent RALP between January 2018 and June 2019. Patients were allocated to one of two groups; group 1 (n=60) underwent RALP with BNS, group 2 (n=60) underwent RALP with both AUF and BNS. The patient continence status was measured at baseline on day 7 and in the 1st, 3rd, and 6th months postoperatively. RESULTS: Concerning Incontinence Impact Questionnaire-7 form, statistically significant better results in group 2 were recorded in all visits, but the last (month 6) (p=0.023). Following catheter removal, postmicturition symptoms, including incomplete emptying and post-micturition dribble rate, were significantly higher in group 1 after catheter removal and in the 1st month (13.3% vs. 0 p=0.006). This difference was not recorded at the next visits (months 3 and 6). CONCLUSION: Our findings showed that the combination of AUF and BNS significantly increases early continence rates and decreases post-mictional symptoms after RALP without hampering oncologic outcomes.

Abstract
Background This study was performed to investigate the association between cystographic anastomotic urinary leakage (UL) after retropubic radical prostatectomy (RRP) and early urinary incontinence (UI). Methods The medical records of 53 patients who had undergone cystography after RRP at our institution between January 2015 and December 2018 were retrospectively analyzed. Cystography was performed 7 to 10 days after surgery. The duration of catheterization depended on the degree of UL, which was classified as mild, moderate, or severe. The study subjects were divided into the non-UL group and the UL group. Continence was defined as the use of no pads. The prostate was dissected in an antegrade fashion, and urethrovesical anastomosis was performed with a continuous suture. Results Incontinence rates at 1 and 3 months postoperatively were significantly higher in the UL group than the non-UL group (83.3% vs. 52.2%, p=0.014 and 76.7% vs. 47.8%, p=0.030, respectively); however, those at 6 and 12 months were not significantly different (23.3% vs. 17.4%, p=0.597 and 4.3% vs. 10.0%, p=0.440, respectively). The severity of UL was not found to influence the duration of incontinence. The presence of cystographic anastomotic UL was found to be predictive of UI during the first 3 postoperative months (odds ratio, 3.3; p=0.045). Conclusion The presence of anastomotic UL on cystography was associated with higher rates of UI in the early postoperative periods. However, incontinence rates in patients with or without anastomotic UL immediately after RRP equalized at 6 months and the severity of UL did not affect the duration of postoperative UI.

Association between patient-initiated emails and overall 2-year survival in cancer patients undergoing chemotherapy: Evidence from the real-world setting. Cancer Med 2020; 9:8552-8561. [PMID: 32986931 PMCID: PMC7666724 DOI: 10.1002/cam4.3483] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 07/09/2020] [Accepted: 09/02/2020] [Indexed: 11/12/2022] Open
Abstract
PURPOSE Prior studies suggest email communication between patients and providers may improve patient engagement and health outcomes. The purpose of this study was to determine whether patient-initiated emails are associated with overall survival benefits among cancer patients undergoing chemotherapy. PATIENTS AND METHODS We identified patient-initiated emails through the patient portal in electronic health records (EHR) among 9900 cancer patients receiving chemotherapy between 2013 and 2018. Email users were defined as patients who sent at least one email 12 months before to 2 months after chemotherapy started. A propensity score-matched cohort analysis was carried out to reduce bias due to confounding (age, primary cancer type, gender, insurance payor, ethnicity, race, stage, income, Charlson score, county of residence). The cohort included 3223 email users and 3223 non-email users. The primary outcome was overall 2-year survival stratified by email use. Secondary outcomes included number of face-to-face visits, prescriptions, and telephone calls. The healthcare teams' response to emails and other forms of communication was also investigated. Finally, a quality measure related to chemotherapy-related inpatient and emergency department visits was evaluated. RESULTS Overall 2-year survival was higher in patients who were email users, with an adjusted hazard ratio of 0.80 (95 CI 0.72-0.90; p < 0.001). Email users had higher rates of healthcare utilization, including face-to-face visits (63 vs. 50; p < 0.001), drug prescriptions (28 vs. 21; p < 0.001), and phone calls (18 vs. 16; p < 0.001). Clinical quality outcome measure of inpatient use was better among email users (p = 0.015). CONCLUSION Patient-initiated emails are associated with a survival benefit among cancer patients receiving chemotherapy and may be a proxy for patient engagement. As value-based payment models emphasize incorporating the patients' voice into their care, email communications could serve as a novel source of patient-generated data.

Effect of Bladder Neck Preservation on Long-Term Urinary Continence after Robot-Assisted Laparoscopic Prostatectomy: A Systematic Review and Meta-Analysis. J Clin Med 2019; 8:jcm8122068. [PMID: 31771310 PMCID: PMC6947283 DOI: 10.3390/jcm8122068] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 11/13/2019] [Accepted: 11/22/2019] [Indexed: 02/06/2023] Open
Abstract
This study aimed to evaluate the effect of bladder neck preservation (BNP) on long-term urinary continence after robot-assisted laparoscopic prostatectomy (RALP). We systematically searched the PubMed, Embase, and Cochrane Library databases to identify studies that assessed the difference in urinary continence and oncologic outcomes between patients who underwent RALP with BNP and those who underwent RALP without BNP. Four trials (1880 cases with BNP, 727 controls without BNP) were considered suitable for meta-analysis. BNP was associated with significantly better urinary continence outcomes at 3–4 months (odds ratio (OR), 2.88; 95% confidence interval (CI), 1.52–5.48; p = 0.001), 12 months (OR, 2.03; 95% CI, 1.10–3.74; p = 0.02), and 24 months (OR, 3.23; 95% CI, 1.13–9.20; p = 0.03) after RALP. There was no difference in the rate of overall positive surgical margin (PSM) (OR, 1.00; 95% CI, 0.72–1.39; p = 0.99) and that of PSM at the prostate base (OR, 0.49; 95% CI, 0.21–1.13; p = 0.09) between the two groups. The BNP technique during RALP leads to early return of urinary continence and long-term urinary continence without compromising the oncologic outcomes.

Abstract
PURPOSE To assess whether the preoperative 1-h pad test could predict postoperative urinary incontinence and quality of life after robot-assisted radical prostatectomy. METHODS A total of 329 patients who underwent robot-assisted radical prostatectomy between 2013 and 2016 were prospectively enrolled in this study. These patients were divided into the preoperative urinary continence group and the preoperative urinary incontinence group according to the 1-h pad test. The time to achieve urinary continence, lower urinary tract function evaluated by uroflowmetry and post-voided residual urine volume, and quality of life evaluated by King's Health Questionnaire and International Consultation on Incontinence Questionnaire-Short Form were compared between these two groups. RESULTS There were 190 patients (58%) in the preoperative urinary continence group (1-h pad test ≤ 2 g) and 139 patients (42%) in the preoperative urinary incontinence group (1-h pad test > 2 g). In the preoperative urinary continence/incontinence groups, 83%/76% of patients achieved continence within 12 months, respectively, and urinary incontinence remained significantly longer in the preoperative incontinence group than in the preoperative continence group (P = 0.042). Although there were no significant differences in all quality of life items between the two groups before surgery, several items were significantly higher in the preoperative urinary continence group. CONCLUSION Achievement of urinary continence and improvement of urinary quality of life are delayed in patients with preoperative urinary incontinence assessed by the 1-h pad test. The preoperative 1-h pad test could be a useful predictor of prolonged urinary incontinence and poor quality of life after robot-assisted radical prostatectomy.

Abstract
We aimed to investigate whether preoperative MRI findings could predict the bladder neck location on postoperative cystography and recovery of urinary incontinence after robot-assisted laparoscopic radical prostatectomy (RALP). We retrospectively reviewed 270 consecutive patients who had complete preoperative data, including MRI, and underwent postoperative observation for more than three months. Preoperative MRI parameters consisted of the membranous urethral length (MUL) and pubic symphysis-prostate apex length (PAL) on sagittal images. The bladder neck location on a postoperative cystography was defined as the lowest extension of the tapering contrast medium in the bladder, and its relation to the pubic symphysis (above (higher group) and below (lower group) the middle of the pubic symphysis height) was evaluated. Those who required no pad or a safety pad were defined as being continent. PAL was significantly shorter in the higher group than that in the lower group (25.5 vs. 29.1 mm; p < 0.0001). The continent group at three months had a significantly longer MUL and shorter PAL than those in the incontinent group (8.1 vs. 6.7 mm; p < 0.05, and 26.0 vs. 28.1 mm; p < 0.05, respectively). Preoperative MRI parameters could predict the bladder neck location on postoperative cystograms and the recovery of urinary incontinence after RALP.

Abstract
Background Post-radical prostatectomy urinary incontinence (PPI) negatively affects the quality of life of patients. Accurate identification of the problem by physicians is essential for adequate postoperative management. In this study we sought to access whether there is, for urinary incontinence, any discrepancy between medical reports and the perception of patients. Methods We performed a retrospective analysis of medical records of 337 patients subjected to radical retropubic prostatectomy (RRP) between 2005 and 2010. Sociodemographic variables were collected, as well as continence status over the course of treatment. Next, we contacted patients by phone to determine continence status at present and at time of their last appointment, as well as to apply ICIQ – SF questionnaire. Poisson regression model with robust variance was used to estimate the factors associated with discrepancy, using the stepwise backward strategy. Software used was Stata® (StataCorp, LC) version 11.0. Results There is discrepancy between medical reports and patients’ perceptions in 42.2% of cases. This discrepancy was found in 56% of elderly patients and 52% of men with low schooling, with statistical significance in these groups (p = 0.069 and 0.0001, respectively), whereas in multivariate regression analysis the discrepancy rate was significantly higher in black men (discrepancy rate of 52.6%) with low schooling (p = 0.004 and 0.043, respectively). Conclusion There is discrepancy between medical reports and the perception of black men with low schooling in respect to post-radical prostatectomy urinary incontinence and a need for more thorough investigation of this condition in patients that fit this risk profile.

Abstract
PURPOSE This randomized clinical trial compared a personally tailored, automated telephone symptom management intervention to improve self-management among long-term survivors of prostate cancer with usual care enhanced with a nontailored newsletter about symptom management. We hypothesized that intervention-group participants would have more confident symptom self-management and reduced symptom burden. METHODS A total of 556 prostate cancer survivors who, more than 1 year after treatment, were experiencing symptom burden were recruited from April 2015 to February 2017 across four Veterans Affairs sites. Participants were randomly assigned to intervention (n = 278) or usual care (n = 278) groups. We compared differences in the primary (symptom burden according to Expanded Prostate Cancer Index Composite-26 [EPIC], confidence in self-management) and secondary outcomes between groups using intent-to-treat analyses. We compared domain-specific changes in symptom burden from baseline to 5 and 12 months among the intervention group according to the primary symptom focus area (urinary, bowel, sexual, general) of participants. RESULTS Most of the prostate cancer survivors in this study were married (54.3%), were white (69.2%), were retired (62.4%), and underwent radiation therapy (56.7% v 46.2% who underwent surgery), and the mean age was 67 years. There were no baseline differences in urinary, bowel, sexual, or hormonal domain EPIC scores across groups. We observed higher EPIC scores in the intervention arm in all domain areas at 5 months, though differences were not statistically significant. No differences were found in secondary outcomes; however, coping appraisal was higher (2.8 v 2.6; P = .02) in intervention-arm patients at 5 months. In subgroup analyses, intervention participants reported improvement from baseline at 5 and 12 months in their symptom focus area domains. CONCLUSION This intervention was well received among veterans who were long-term survivors of prostate cancer. Although overall outcome differences were not observed across groups, the intervention tailored to symptom area of choice may hold promise to improve associated burden.

A Randomized Control Trial Of Anti-Inflammatory Regional Hypothermia On Urinary Continence During Robot-Assisted Radical Prostatectomy. Sci Rep 2018; 8:16352. [PMID: 30397236 PMCID: PMC6218497 DOI: 10.1038/s41598-018-34657-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Accepted: 10/05/2018] [Indexed: 12/16/2022] Open
Abstract
The present study seeks to present a single-blind, randomized control trial of a hypothermic anti-inflammatory device, the endorectal cooling balloon (ECB), to assess whether regional hypothermia could improve 90-day and time to pad-free continence following robot-assisted radical prostatectomy (RARP). Five high-volume surgeons at three institutions had patients randomized (1:1) to regional hypothermia with ECB versus control. Patients were blinded to device use, as it was inserted and removed intraoperatively. Knowledge of device use was restricted to the operating room personnel only; recovery room and ward nursing staff were not informed of device use and instructed to indicate such if a patient inquired. An independent and blinded data acquisition contractor assessed outcomes via components of the EPIC and IPSS. The primary outcome was categorical pad-free continence at 90-days and the secondary outcome was a Kaplan-Meier time-to pad-free continence at 90 days. 100 hypothermia and 99 control patients were included. The primary outcome of 90-day pad-free continence was 50.0% (27.8-70.0%) in the hypothermia group versus 59.2% (33.3-78.6%) in the control (p = 0.194). The secondary outcome of Kaplan Meier analysis for time to 90-day continence was not statistically significant. At one year, there were also no statistically significant differences in continence recovery. Post-hoc analysis revealed a trend towards improvement in continence in one of three sites. Overall, the trial demonstrated no benefit to regional hypothermia either in our primary or secondary outcomes. It is suggested that surgical technique and prevention of surgical trauma may be more advantageous to improving continence recovery.

Bladder neck preservation improves time to continence after radical prostatectomy: a systematic review and meta-analysis. Oncotarget 2018; 7:67463-67475. [PMID: 27634899 PMCID: PMC5341889 DOI: 10.18632/oncotarget.11997] [Citation(s) in RCA: 50] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2016] [Accepted: 08/26/2016] [Indexed: 12/02/2022] Open
Abstract
Bladder neck preservation (BNP) during radical prostatectomy (RP) may improve postoperative urinary continence, although its overall effectiveness remains controversial. We systematically searched PubMed, Ovid Medline, Embase, CBM and the Cochrane Library to identify studies published before February 2016 that assessed associations between BNP and post-RP urinary continence. Thirteen trials (1130 cases and 1154 controls) assessing BNP versus noBNP (or with bladder neck reconstruction, BNR) were considered suitable for meta-analysis, including two randomized controlled trials (RCT), six prospective and five retrospective studies. Meta-analysis demonstrated that BNP improved early urinary continence rates (6 mo, OR = 1.66; 95% CI, 1.21–2.27; P = 0.001) and long-term urinary continence outcomes (>12 mo, OR = 3.99; 95% CI, 1.94–8.21; P = 0.0002). Patients with BNP also had lower bladder neck stricture frequencies (OR = 0.49; 95% CI, 0.29–0.81; P = 0.006). Anastomotic leak rates, positive surgical margins and biochemical failure rates were comparable between the two groups (P>0.05). There were no differences in baseline characteristics except for a smaller average prostate volume (WMD = −2.24 ml; 95% CI, -4.27 to -0.22; P = 0.03) in BNP patients. Our analyses indicated that BNP during RP improved early recovery and overall long-term (1 year) urinary continence and decreased bladder neck stricture rates without compromising oncologic control.

A match-pair analysis of continence in intermediate and high-risk prostate cancer patients after robot-assisted radical prostatectomy: the role of urine loss ratio and predictive analysis. Prostate Int 2017; 6:94-98. [PMID: 30140658 PMCID: PMC6104473 DOI: 10.1016/j.prnil.2017.09.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2017] [Revised: 08/17/2017] [Accepted: 09/13/2017] [Indexed: 12/13/2022] Open
Abstract
Background We aimed to study the continence between intermediate and high-risk cancer patients and the influential factors to recover continence. Materials and methods In total, 655 patients underwent surgery by robot-assisted radical prostatectomy between 2010 and 2015. Of 655 patients, 294 were classified according to D'Amico risk groups as intermediate risk or high risk and completed the micturition protocol. Patients with intermediate risk were matched in a 1:1 ratio to patients with high risk for age and body mass index. Urine loss ratio (ULR) was defined as urine loss divided by micturition volumes. Immediate continence was defined with the best cut-off value of ULR. Results In total, 117 patients with intermediate risk were matched to those with high risk. The comparison did not show any statistically significant difference in the ULR value (P = 0.359) or continence rate (P = 0.449). Predictive analysis was performed for the 294 patients (intermediate and high risk), of which 9.5% were classified as incontinent (>1 pad/d). Immediate continence was defined as ULR < 0.049 in 232 (78.9%) patients. Age, preoperative hemoglobin, and duration of catheterization were found influent by univariate analysis. Only age [odds ratio (OR) = 1.072; 95% confidence interval (CI) = 1.020–1.127; P = 0.006] and duration of catheterization (OR = 1.060; 95% CI = 1.003–1.120; P = 0.040) were independent influential factors to predict immediate continence. Conclusion D'Amico intermediate- and high-risk groups do not differ in continence terms. The ULR value of < 0.049 identifies those patients who recover continence earlier. Age and duration of catheterization were influential factors in predicting immediate continence.

Abstract
Objectives To assess the use of post radical prostatectomy (RP) urinary incontinence (PPI) surgery and to investigate factors related to its use. Methods Cohort study in Prostate Cancer database Sweden (PCBaSe) of men who underwent primary RP between 1998 and 2012. PPI correction procedures were identified in the Patient Registry. Hazard ratios (HR) and 95% confidence intervals (CIs) of PPI surgeries were estimated. Results Seven hundred eighty‐two out of 26 280 (3%) men underwent PPI surgery at a median time of 3 years after RP. There was an eightfold increase in the absolute number of PPI surgeries during 2000‐2014 and a threefold increase in the number per 1000 RPs performed. Factors associated with high use PPI surgery were age >70, HR 1.96 (1.54‐2.50), and high hospital RP volume (>100 RPs/year), HR 0.81 (0.66‐0.99). There was a 10‐fold difference in use of PPI surgery per 1000 RPs between the county with the highest versus lowest use. In a subgroup of men with Patient‐Reported Outcome Measures (PROM); severe PPI was reported by 7% of men and 24% of them underwent PPI surgery. Conclusions Three percent of all men received PPI surgery, with a 10‐fold variation among health care providers. Only a quarter of men with severe PPI underwent PPI surgery, suggesting that PPI surgery remains underutilized.

Abstract
Background Although prostate cancer is the most common cancer among veterans receiving care in the Veterans Health Administration (VA), more needs to be done to understand and improve survivorship care for this large population. This study, funded by VA Health Services Research & Development (HSR&D), seeks to address the need to improve patient-centered survivorship care for veterans with prostate cancer. Methods/Design This is a two-armed randomized controlled trial (RCT) with a target enrollment of up to 325 prostate cancer survivors per study arm (total anticipated n = 600). Patients will be recruited from four VA sites. Patient eligibility criteria include age range of 40–80 years, one to ten years post-treatment, and currently experiencing prostate cancer symptom burden. We will compare the “Building Your New Normal” program, a personally-tailored automated telephone symptom management intervention for improving symptom self-management to usual care enhanced with a non-tailored newsletter about symptom management. Primary outcomes include changes in symptom burden, bother, and health services utilization at five and 12 months after enrollment. Secondary outcomes include long-term psychosocial outcomes (e.g. subjective health, perceived cancer control). We will use multivariable regression analysis to evaluate the impact of the intervention on primary and secondary outcomes. We will conduct a process evaluation to understand the effective intervention components and explore possibilities for broader implementation and dissemination. Discussion Our central hypothesis is that intervention group participants will have improved and more confident symptom self-management and prostate cancer quality of life following the intervention and that these outcomes will translate to more efficient use of health services. The study results will provide much needed information about how to optimize the quality of care, and life, of veteran prostate cancer survivors.

Preoperative Membranous Urethral Length Measurement and Continence Recovery Following Radical Prostatectomy: A Systematic Review and Meta-analysis. Eur Urol 2016; 71:368-378.

Abstract
CONTEXT Membranous urethral length (MUL) measured prior to radical prostatectomy (RP) has been identified as a factor that is associated with the recovery of continence following surgery. OBJECTIVE To undertake a systematic review and meta-analysis of all studies reporting the effect of MUL on the recovery of continence following RP. EVIDENCE ACQUISITION A comprehensive search of PubMed, EMBASE, and Scopus databases up to September 2015 was performed. Thirteen studies comprising one randomized controlled trial and 12 cohort studies were selected for inclusion. EVIDENCE SYNTHESIS Four studies (1738 patients) that reported hazard ratio results. Every extra millimeter (mm) of MUL was associated with a faster return to continence (hazard ratio: 1.05; 95% confidence interval [CI]: 1.02-1.08, p<0.001). Eleven studies (6993 patients) reported the OR (OR) for the return to continence at one or more postoperative time points. MUL had a significant positive effect on continence recovery at 3 mo (OR: 1.08, 95% CI: 1.03-1.14, p=0.004), 6 mo (OR: 1.12, 95% CI: 1.09-1.15, p<0.0001). and 12 mo (OR: 1.12, 95% CI: 1.03-1.22, p=0.006) following surgery. After adjusting for repeated measurements over time and studies with overlapping data, all OR data combined indicated that every extra millimeter of MUL was associated with significantly greater odds for return to continence (OR: 1.09, 95% CI: 1.05-1.15, p<0.001). CONCLUSIONS A greater preoperative MUL is significantly and positively associated with a return to continence in men following RP. Magnetic resonance imaging measurement of MUL is recommended prior to RP. PATIENT SUMMARY We examined the effect that the length of a section of the urethra (called the membranous urethra) had on the recovery of continence after radical prostatectomy surgery. Our results indicate that measuring the length of the membranous urethra via magnetic resonance imaging before surgery may be useful to predict a longer period of urinary incontinence after surgery, or to explain a delay in achieving continence after surgery.

Unexpected Long-term Improvements in Urinary and Erectile Function in a Large Cohort of Men with Self-reported Outcomes Following Radical Prostatectomy. Eur Urol 2015; 68:899-905. [PMID: 26293181 DOI: 10.1016/j.eururo.2015.07.074] [Citation(s) in RCA: 50] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2015] [Accepted: 07/31/2015] [Indexed: 11/19/2022]
Abstract
BACKGROUND It is generally assumed that if a man does not regain urinary continence or erectile function within 12 mo of radical prostatectomy (RP), then the chance of subsequent recovery is low. OBJECTIVE To determine the probability of achieving good urinary function (UF) or erectile function (EF) up to 48 mo postoperatively in men who reported poor UF or EF at 12 mo after RP. DESIGN, SETTING, AND PARTICIPANTS We identified 3187 patients who underwent RP from 2007 through 2013 at a tertiary institution and had extended multidisciplinary follow-up with patient-reported UF and EF scores at ≥12 mo. INTERVENTION Open or minimally invasive RP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcome was good UF as defined by a urinary score ≥17 (range: 0-21) or good EF as defined by a modified International Index of Erectile Function-6 score ≥22 (range: 1-30). The probability of functional recovery beyond 12 mo was determined by Kaplan-Meier analyses. RESULTS AND LIMITATIONS Among patients incontinent at 12 mo, the probability of achieving good UF at 24, 36, and 48 mo was 30%, 49%, and 59%. In patients experiencing erectile dysfunction at 12 mo, the probability of recovering EF at 24, 36, and 48 mo was 22%, 32%, and 40%. On multivariable analyses, 12-mo functional score and age were associated with recovery, but only score was consistently significant. CONCLUSIONS Men with incontinence or erectile dysfunction at 12 mo have higher than anticipated rates of subsequent functional improvement. Probability of recovery is strongly influenced by score at 12 mo. Further research should address the impact of ongoing multidisciplinary follow-up care on our observed rates of recovery. PATIENT SUMMARY Many prostate cancer patients continue to recover urinary and erectile function after 12 mo. The level of functional recovery by 12 mo is associated with long-term recovery and should be discussed by the physician and patient when deciding on rehabilitative interventions.

Urinary Continence Outcomes after Puboprostatic Ligament Preserving Open Retropubic Radical Prostatectomy at a Sub-Saharan Hospital. INTERNATIONAL SCHOLARLY RESEARCH NOTICES 2014; 2014:986382. [PMID: 27382635 PMCID: PMC4897278 DOI: 10.1155/2014/986382] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/09/2014] [Accepted: 12/04/2014] [Indexed: 12/03/2022]
Abstract
Background. Open retropubic radical prostatectomy is a commonly performed procedure for clinically localized prostate cancer. The demand for high level functional outcomes after therapy is increasing especially for young age patients; in this regard refinements in the surgical technique have been made. There is limited data to show the success of some of these refinements in resource limited settings. Methods. A retrospective clinical study was performed over a 2-year period at Mengo Hospital, Urology Unit. Men with clinically localized prostate cancer and who consented to the procedure were eligible and were recruited. Consequently excluded were those that turned out to have advanced disease and those with severe comorbidities. Patients were followed up for 3 months after surgery. Data was entered using SPSS version 17 and analyzed. Results. A total of 24 men with clinically localized prostate cancer underwent open retropubic puboprostatic ligament preserving radical prostatectomy technique. Mean age was 66, range 54–75 years. Outcome. Two patients had stress incontinence and three were incontinent at 3 months. The urinary continence recovery rate was 19/24 (79%) at 3 months. Conclusion. Preservation of the puboprostatic ligament in open retropubic radical prostatectomy was associated with rapid and a high rate of return to urinary continence among men with clinically localized disease.

Abstract
Damage to peripheral nerves caused during a surgical intervention often results in function loss. Fluorescence imaging has the potential to improve intraoperative identification and preservation of these structures. However, only very few nerve targeting agents are available. This study describes the in vivo nerve staining capabilities of locally administered fluorescent lectin-analogues. To this end WGA, PNA, PHA-L and LEL were functionalized with Cy5 (λex max 640 nm; λem max 680 nm). Transfer of these imaging agents along the sciatic nerve was evaluated in Thy1-YFP mice (n = 12) after intramuscular injection. Migration from the injection site was assessed in vivo using a laboratory fluorescence scanner and ex vivo via fluorescence confocal microscopy. All four lectins showed retrograde movement and staining of the epineurium with a signal-to-muscle ratio of around two. On average, the longest transfer distance was obtained with WGA-Cy5 (0.95 cm). Since WGA also gave minimal uptake in the lymphatic system, this lectin type revealed the highest potential as a migration imaging agent to visualize nerves.

Abstract
Urinary incontinence after prostatectomy or radiation is a devastating problem in men and remains the most feared complication following the treatment of localized prostate cancer. With an increasing number of radical prostatectomies performed globally for prostate cancer, the impact of urinary incontinence on quality of life assumes an even greater importance. With the advent of male sling procedures, more men are now seeking treatment for incontinence. Since the introduction of the artificial urinary sphincter almost four decades ago, several surgical procedures have emerged to manage post-prostatectomy incontinence, including the male sling for milder forms of incontinence. Several of the newer procedures have shown promise in the United States; many others have been developed and utilized in other parts of the world, though they have not yet gained FDA approval in the United States. The present review seeks to illuminate the etiology, evaluation, and management of post-prostatectomy incontinence. An effort has been made to provide an algorithm to clinicians for appropriate surgical management. The surgical techniques of commonly performed procedures and their outcomes are described.

Abstract
Background The goal of this study is to demonstrate the efficacy of a new method for the treatment of urinary incontinence by stimulation of urethral rhabdosphincter satellite cells. We show that satellite cells do exist in the sphincter muscle of retired male mice breeders by staining for c-Met, a satellite cell specific protein. Once activated by recombinant mouse Insulin-like Growth Factor-1(rIgf-1), the satellite cells develop into muscle cells within the rhabdosphincter thereby potentially strengthening it. Methods 20 μl (1 μg/μl) of rIgf-1 was surgically injected directly into the urethral wall of retired male mouse breeders. Mice injected with phosphate buffered saline (PBS) were used as controls. 4 weeks later, urethras were harvested and serially-sectioned through the sphincter for routine hematoxylin-eosin staining as well as immunohistochemical staining with satellite cell specific anti-c-Met antibody and proliferation specific anti-Ki-67 antibody. Results Anti-c-Met antibody positive cells (c-Met+) were identified in the rhabdosphincter. c-Met+ cells increased by 161.8% relative to controls four weeks after rIGF-1 injection. Anti- Ki-67 antibody positive cells were identified and characterized as cells with centrally located nuclei in striated muscle bundles of rIGF-1 treated animals. Conclusions Satellite cells in the mouse rhabdosphincter can be activated by rIGF-1 treatment, which subsequently are incorporated into existing skeletal muscle bundles. Using this approach, the rhabdosphincter can be induced to regenerate and potentially strengthen via satellite cell activation and likely improve urinary continence.

Abstract
INTRODUCTION Immediate continence is a goal to take into consideration for better patient satisfaction after radical prostatectomy. Factors predicting urinary continence at catheter removal were investigated. MATERIALS AND METHODS We evaluated preoperative, operative, clinical, hormonal and pathological variables in a homogeneous series of radical retropubic prostatectomies (RRPs) following the principles of urinary sphincter restoration technique. RESULTS The study included 201 patients who underwent RRP. The overall immediate continence rate at catheter removal was 67.7% (136 patients); 28.8% (58 patients) were using one protective pad daily and 3.5% (7 patients) were incontinent. At 6-month follow-up incontinence had reached the lowest level of 2.5% (5 patients) and at 12 months the patients using one pad daily had decreased to 11.9% (24 patients). Multivariate logistic analysis showed that the only two factors independently associated with immediate continence were age <65 years (OR = 2.63, 95% CI 1.13-5.88, p = 0.02) and potency (OR = 3.6, 95% CI 1.2-10.7, p = 0.01) adjusting for D'Amico risk group, surgical margins, extracapsular extension, clinical stage, PSA, testosterone, LH and FSH. No significant association was noted for PSA, hormonal levels, hospital stay, prostate size, clinical stage, risk group, TNM stage, pathological Gleason score or extracapsular extension. CONCLUSIONS In our series age <65 years was associated with immediate continence after RRP. Moreover, patients who were immediately continent had a 3.6-fold probability to be potent within 12 months.

Abstract
Purpose To evaluate the recovery of continence after robot-assisted laparoscopic prostatectomy (RALP) and open radical retropubic prostatectomy (RRP). Materials and Methods We identified 258 patients who underwent surgery by a single surgeon to treat localized prostate cancer. The patients were divided into two groups according to operative method. In group 1, 146 consecutive patients underwent RALP, and in group 2, 112 patients underwent RRP. To compare the interval until the return of urinary continence between the two groups, we used the Kaplan-Meier method and the log-rank test and Cox proportional hazard regression analyses. Results Differences between the two groups were found in mean estimated blood loss (EBL; p<0.001) and the rate of nerve sparing (p=0.004). When continence was defined as the use of 0 to 1 pad per day, 100% of group 1 and 98.2% of group 2 reported continence at 12 months (p=0.189). When continence was defined as no pad use, however, there was a significant difference between the two groups at 12 months: group 1, 95.7%, and group 2, 70.7% (p<0.001). The factors affecting time until no pad use in the univariate analysis with a Cox proportional hazards model were operation method, age, neurovascular bundle saving, membranous urethral length (MUL), EBL, and apical shape. In the multivariate analysis, only operation method, age, and MUL retained significance. Conclusions Our study suggests that RALP is an independent factor for the recovery of continence and that RALP has advantages for postoperative continence recovery and the quality of continence compared with RRP.

Abstract
OBJECTIVE The aim of this study was to examine the effects of the retropubic and perineal radical prostatectomy techniques on postoperative urinary continence. MATERIAL AND METHODS This study included patients who had undergone radical retropubic (RRP) (n=54) or radical perineal prostatectomies (RPP) (n=142) in our clinic between December 2006 and December 2010 with the indication of localized prostate cancer. Preoperative, and postoperative continence levels of the patients were evaluated on the day of catheter removal, and at 3., 6. or 12. months using University of California-Los Angeles (UCLA) prostate cancer index query forms completed by the patients themselves in outpatient clinics. RESULTS Mean ages of the perineal, and retropubic groups were 62.3 (48-77), and 62.5 (50-74) years, respectively. The absolute urinary control rates of the RPP patients on the first days, and the first, third, sixth, and twelfth months were 44.3, 63.6, 76.2, 79.5, and 86.1%, respectively. The same rates were 51.4, 75.7, 78.4, 89.2, and 91.9% for the RRP group, respectively. CONCLUSION There was no significant difference between RRP groups as for the frequency of urinary incontinence.

Abstract
Purpose We analyzed factors associated with early recovery of continence after laparoscopic radical prostatectomy. Materials and Methods Among 467 patients treated with laparoscopic radical prostatectomy for localized prostate cancer between 2007 and 2012, 249 patients who underwent a preoperative urodynamic study were enrolled. The patients' age, prostate volume, preoperative serum prostate-specific antigen (PSA), Gleason score, pathologic stage, and preoperative urodynamic parameters were recorded. The preoperative membranous and prostatic urethral length on magnetic resonance image, nerve sparing technique, and type of surgical procedure (extrafascial and intrafascial) were analyzed. Patients were considered to have early recovery of continence when they needed no pad in 3 months or less after surgery. Results Ninety-two patients were in the early recovery group and 157 were in the late recovery group. The membranous urethral lengths were 12.06±2.56 and 11.81±2.87 mm, and prostatic urethral lengths were 36.39±6.15 and 37.45±7.55 mm in each group, respectively. The membranous-posterior urethral length ratios were 0.25±0.06 and 0.24±0.06, and prostatic-posterior urethral length ratios were 0.75±0.06 and 0.76±0.06, respectively. In and of themselves, the membranous and prostatic urethral lengths were not associated with recovery duration however, the membranous-total and prostatic-total urethral length ratios were related (p=0.024 and 0.024, respectively). None of the urodynamic parameters correlated with continence recovery time. In the multivariate analysis, the type of surgical procedure (odds ratio [OR], 7.032; 95% confidence interval [CI], 2.660 to 18.590; p<0.001) and membranous urethral length (OR, 0.845; 95% CI, 0.766 to 0.931; p=0.001) were significantly related to early recovery of continence. Conclusions The current intrafascial surgical procedure is the most important factor affecting early recovery of continence after laparoscopic radical prostatectomy.

Abstract
BACKGROUND Urinary incontinence is a common short-term complication of radical prostatectomy (RP). Little is known about the long-term impact of RP on continence. OBJECTIVE To elucidate the long-term progression of continence after RP. DESIGN, SETTING, AND PARTICIPANTS From October 2000 through September 2012, 1788 men undergoing open RP for clinically localized prostate cancer by a single surgeon at an urban tertiary care center prospectively signed consent to be followed before RP and at 3, 6, 12, 24, 96, and 120 mo after RP. A consecutive sampling method was used and all men were included in this study. INTERVENTION Men underwent open RP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Regression models controlled for preoperative University of California, Los Angeles-Prostate Cancer Index urinary function score (UCLA-PCI-UFS), age, prostate-specific antigen level, Gleason score, stage, nerve-sparing status, race, and marital status were used to evaluate the association of time since RP with two dependent variables: UCLA-PCI-UFS and continence status. RESULTS AND LIMITATION The mean UCLA-PCI-UFS declined between 2 yr and 8 yr (83.8 vs 81.8; p=0.007) and marginally between 8 yr and 10 yr (81.8 vs 79.6; p=0.036) after RP, whereas continence rate did not significantly change during these intervals. Men ≥ 60 yr old experienced a decline in mean UCLA-PCI-UFS between 2 yr and 8 yr (p=0.002) and a marginal decline in continence rate between 2 yr and 10 yr (p=0.047), whereas these variables did not change significantly in men <60 yr old. These outcomes are for an experienced surgeon, so caution should be exercised in generalizing these results. CONCLUSIONS Between 2 yr and 10 yr after RP, there were slight decreases in mean UCLA-PCI-UFS and continence rates in this study. Men aged <60 yr had better long-term outcomes. These results provide realistic long-term continence expectations for men undergoing RP.

Abstract
Radical prostatectomy (RP) is a recognized treatment method of organ-confined prostate cancer. Among post-surgery complications, urinary incontinence is a major one. The aim of this study was to determine the incontinence rate after RP and to analyze factors that might affect it. Between March 2007 and December 2008, 132 RP's were performed at Warsaw Cancer Center. A questionnaire to assess the condition before and after RP was developed by the authors and sent to all treated patients. The questionnaire focused on health status information, function in urinary domain, rate of returning to "normal" activity level as before RP and satisfaction from the treatment. The median age of patients was 62 years. Out of 132 patients 102 subjects (77.2%) responded to the questionnaire. Of all responders, 35 patients (34.3%) reported total urinary continence after RP. After RP 35(34.3%) patients reported total urinary continence and in 55(53.9%) patients urinary incontinence of medium degree was present. In 12 (11.8%) patients significant urinary incontinence developed. The most common cause of urine dripping (82% of patients with any degree of urinary incontinence) was associated with abdominal muscle pressure. No statistically significant association between urinary incontinence and adjuvant radiotherapy after RP or the surgeon performing the RP was found (>0.79, >0.803). Radical prostatectomy carries a certain risk of complications. We observed an 88.2% rate of significant (total and moderate degree) urinary continence. The adjuvant radiotherapy and surgeons, who performed the RP, did not affect the rate of incontinence.

Abstract
Urinary incontinence is a major complication following radical prostatectomy. The aim of the present study was to assess the association between urinary continence following laparoscopic radical prostatectomy (LRP) and various factors measured using real-time intraoperative transrectal ultrasonography (TRUS). Patients (n=53) with localized prostate cancer underwent LRP in combination with real-time intraoperative TRUS navigation and were evaluated for urinary continence for more than 6 months following LRP. Prostate size, membranous urethral length (MUL) and bladder-urethra angle were measured using real-time intraoperative TRUS immediately before and after surgery. Urinary continence was regained by 4, 15 and 27 patients 1, 3 and 6 months after LRP, respectively. Longer postoperative MUL was significantly correlated with recovery of urinary continence 1, 3 and 6 months after LRP. In addition, an increase in difference between preoperative and postoperative MUL was also associated with superior continence. No correlation was observed between postoperative MUL and the rate of tumor-positive surgical margins. Larger prostate volume was correlated to postoperative continence 6 months after surgery. Shorter operation time and less blood loss resulted in postoperative urinary continence 1 month after LRP. Preoperative MUL, bladder-urethra angle, age and body mass index had no correlation with urinary continence. Postoperative MUL was the most significant factor for early recovery of urinary continence following LRP. These results indicate that preservation of longer urethra during surgery may be recommended without tumor-positive surgical margins.

Abstract
INTRODUCTION Urinary continence significantly affects quality of life after radical prostatectomy (RP). The impact of nerve-sparing surgery on continence is unclear from the current literature. METHODS We identified men with prostate cancer from the University Health Network Prostate Centre database who underwent RP. Preoperatively and at each postoperative visit, patients completed the Patient-Oriented Prostate Utility Scale (PORPUS), a validated psychometric and health utility instrument. Incontinence was defined by a single questionnaire item. Patients with radiotherapy or less than 10 months follow-up were excluded. Chi-squared tests and ANOVA were used to compare groups. Multivariable logistic regression was used to control for effects of nerve-sparing and other covariates. RESULTS Of the 253 eligible patients from 2003 to 2007, 159 patients had bilateral nerve-sparing, 32 had unilateral nerve-sparing and 62 had non-nerve-sparing surgery. Of these patients, 27%, 17% and 34%, respectively, were classified as incontinent at 1 year. These proportions were not significantly different between groups (p = 0.23). Multivariable logistic regression showed baseline urinary continence and urinary frequency to be significant predictors of patient-reported continence at 1 year postoperatively, with odds ratios of 1.7 (95% confidence interval [CI] 1.1-2.9) and 1.5 (95% CI 1.0-2.3), respectively. There was a significant difference in the proportion of PORPUS sexual function scores between nerve-sparing groups after excluding those with baseline sexual dysfunction (p = 0.003). Similarly, health-related utility scores were different across groups (p < 0.001). CONCLUSION Our results do not suggest a difference in 1-year patient-reported continence based on the type of nerve-sparing RP. However, baseline continence and urinary frequency were significant predictors of continence at 1 year.

Abstract
The diagnosis and management of male stress urinary incontinence (SUI) is complex. Various etiologies exist, with radical prostatectomy being the most common cause in men seeking treatment. SUI in this setting is often temporary and resolves within the first postoperative year. Therefore, it is important to understand the natural history of male SUI before initiating treatment. Generally, the initial management of SUI that persists after 12 months consists of conservative measures, such as pelvic floor muscle exercises. Several treatments are available for men whose continence does not improve after pelvic floor muscle exercises. In order of increasing complexity they are urethral bulking agents, male slings, and the artificial urinary sphincter (AUS). With over 30 years of published data suggesting excellent long-term outcomes, the AUS is considered the gold standard treatment of male SUI. Male slings have recently demonstrated efficacy for selected patients and are likely to be used more often in the future as experience with these devices grows.

Abstract
Success of radical prostatectomy is measured by control of cancer and return of urinary and sexual function. Urinary incontinence is generally considered the greatest impairment in immediate postoperative urinary function. Multiple factors are associated with earlier return of urinary continence after radical prostatectomy. These factors can be divided into those known prior to surgery, and therefore possibly not modifiable, and factors that can be controlled during surgery or surgical planning. In addition, various postoperative maneuvers can help hasten urinary continence. This article examines the effect of known factors related to early return of urinary continence after radical prostatectomy.

Abstract
Postoperative stress incontinence following operative treatment of prostate cancer represents a considerable percentage of overall male incontinence. Postoperative incontinence following radical prostatectomy ranges between 2.9 and 87% depending on author and patient characteristics. Especially patient-related factors such as body mass index, age, size of prostate, preoperative incontinence, and concomitant diseases as well as classification of incontinence and modality of data collection influence postoperative continence rates. However, recent publications demonstrate the important impact of different operative techniques with regard to postoperative continence.The preservation of the muscular urethral sphincter is of particular importance. Nevertheless, the preservation of further anatomical structures contributes to postoperative continence. Preservation of bladder neck, nerve sparing, and reconstruction of the vesicourethral junction are operative techniques to prevent postoperative incontinence. In the last decade different modifications of the operative technique have been investigated regarding specific effects on postoperative continence. The interpretation of these studies investigating these operative techniques showed improvement in early continence with shorter period of time to continence. Long-term follow-up revealed no significant advantages for these modifications with regard to continence compared to the standard procedure. To evaluate the long-term effects of certain modifications to prevent incontinence, randomized and well powered studies are necessary. It seems to be most likely that a combination of these preventive modifications will lead to improved postoperative continence rates.

Abstract
PURPOSE To compare urinary functional outcomes after LP prostatectomy or robotic assisted laparoscopic prostatectomy performed by a single surgeon regarding to his initial experience. MATERIAL Between March 2005 and April 2007, 247 consecutive patients underwent radical prostatectomy, either by LP approach (125) or by robotic-assisted laparoscopic (RALP) approach (122). The only criteria to chose robot or not, was the Robot Da Vinci's availability. RESULTS There was no statistical difference between the two groups in terms of preoperative characteristics. The continence rate was 83% in PL group versus 81% in RALP group. More precisely, among men wearing at least one pad, 71% of patients in PL groups wear one pad/day versus 87% of patients in RALP group. Multivariate analysis on continence appears to be in favors of RALP group (Odd Ratio 2.1 [CI: 0,86-5,48]). CONCLUSION Incontinence appears to be less severe and frequent in the RALP group. In practice, surgeon's impression of the robot's interest is evident, but more important number of patients and longer follow-up is necessary.

Abstract
OBJECTIVES To report on the long-term results of high-intensity focused ultrasonography (HIFU) in the treatment of localized prostate cancer. METHODS Patients with clinical Stage T1-T2N0M0, biopsy-proven, localized prostate cancer, with a serum prostate-specific antigen (PSA) level of <or=20 ng/mL, Gleason score of <or=7, and with no previous curative prostate cancer treatment, were included. All patients underwent HIFU using the Ablatherm device and were required to have a minimal follow-up of 3 years after the last HIFU session to be included in this analysis. Follow-up included PSA measurement and biopsy performed 3-6 months after treatment and in conjunction with an increasing PSA level. Biochemical failure was defined according to the Phoenix definition (PSA nadir + 2 ng/mL). In determining the disease-free survival rate, treatment was considered to have failed if any of the following occurred: biochemical failure, positive biopsy findings, or the initiation of salvage treatment. RESULTS The study included 163 patients. Within the 4.8 +/- 1.2 years of follow-up, no patient died of prostate cancer. Of the 163 patients, 86.4% achieved a PSA nadir of <1 ng/mL and 92.7% had negative post-treatment biopsy findings. The actuarial biochemical survival rate at 5 years was 75%. The actuarial disease-free survival rate at 5 years was 66%, with salvage treatment initiated for 12% of the patients. On multivariate analysis, the pretreatment PSA level was the only statistically significant predictive factor of recurrence (P = .005). CONCLUSIONS The results after long-term follow-up have indicated that HIFU is an efficient and safe treatment for patients with localized prostate cancer.

Abstract
Stress urinary incontinence is rare in men. Despite the improvements in diagnostic approaches to prostate diseases and surgical interventions on the prostate, stress incontinence has tended to increase in recent decades. The most frightening operative complication for both the patient and the surgeon is incontinence, which is one of the important factors in the treatment of the affected patients. The limited degree of continence considerably lowers the quality of life for the affected men and their partners. There is little information available about the pathophysiology of iatrogenic stress incontinence, which more likely affects older men rather than young men. The available information is based on a few experimental studies. Besides the direct damage to the muscular or neurological component of the external sphincter, insufficient length of the functional urethra and impaired bladder function seem to play an important role in the genesis of postoperative incontinence. In order to improve the postoperative continence status after radical prostatectomy a number of different operative modifications have been introduced. Preservation of the bladder neck, puboprostatic ligaments, and the neurovascular bundle as well as leaving the tips of the seminal vesicles seem to have a positive impact on the degree of postoperative continence.

Abstract
Treatment of locally advanced prostate cancer remains controversial. Treatment options include radical prostatectomy (PR), radiotherapy (RT) and hormonotherapy (HT). A Medline database search with key words "prostate cancer", "locally advanced", "high risk" and "treatment" in articles published during the last 15 years was done. Fifty one out of 329 papers were selected and reviewed. Selection criteria were a minimum of scientific evidence level of IIa, except for some specific level IV reference. Numerous randomized studies show that patients may benefit of a combined therapy with RT and HT. RP has shown its usefulness in selected cases of locally advanced prostate cancer. Results of long follow-up series are similar to those obtained with RT and HT. Furthermore, the possibility of clinical over staging is an argument in favour of RP. We perform an updated revision of every possible choice available in the treatment of these tumours.

Abstract
OBJECTIVE The aim of this study was to assess the continence status and patients' satisfaction after retropubic radical prostatectomy by a self-administered questionnaire composed of 12 questions. MATERIALS AND METHODS In total, 143 patients who underwent RRP operation at our department from 1992 to 2000 with a minimum 6 months of follow-up were assessed. Seventy two patients participated in the study. The continence status was classified as follows; patients who did not leak were considered as "continent", those who had leakage that occurred less frequent than or equal to once a day were regarded as "socially continent", and those who had more than once a day leakage were regarded as "incontinent". The correlation between urinary leakage, patients' satisfaction and pre-operative, peri-operative and post-operative factors were investigated. Univariate and multivariate analyses were done using Fisher's exact, chi-square, Student's-t and logistic regression tests. RESULTS The mean age of patients at surgery was 63.9 years (49-76) with a follow-up period of 37.1 months (6-97). Of these patients, 44% were continent, 48% were socially continent, 8% were incontinent. A total of 64 of 72 patients (89%) were satisfied with their final continence status, and 63 (87%) patients accepted to undergo the same surgery again if it is indicated. Pre-, peri- and post-operative factors did not influence the urinary leakage rates. Patients with nocturnal leakage, urgency, decreased urinary flow and patients who use pad (-s) were significantly less satisfied on univariate analysis, while only nocturnal leakage had a significant impact on patients' satisfaction on multivariate analysis. CONCLUSION Urinary leakage and patients' satisfaction rates after RRP were 56% and 89%, respectively. None of the factors could predict the post-operative continence status. When evaluating the patients' satisfaction, only nocturnal leakage was found to have an adverse affect on multivariate analyses.

Abstract
The aim of this cross-sectional study was to compare single with repeated high-intensity focused ultrasound (HIFU) treatment in patients with localized prostate cancer, regarding treatment-related morbidity. A number of 223 consecutive patients with localized prostate cancer were treated with HIFU. Among them, 174 (78%) patients had one treatment, while 49 (22%) needed a second treatment. The patients' status and treatment-related side effects were followed up. The complications rates after one HIFU in 223 patients were: urinary tract infection 0.4%, chronic pelvic pain 0.9%, infravesical obstruction 19.7%, stressincontinence 7.6%, impotence 49.8%. Among the 49 patients who received a second HIFU therapy, the cumulative incontinence rate (12.2%; P = 0.024) and cumulative impotence rate (55%; P < 0.001) were significantly increased. Although there is an increase in morbidity if transrectal HIFU is repeated, the risk of side effects related to additional HIFU sessions in the case of primary treatment failure is still low.

Abstract
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.

Abstract
OBJECTIVE To examine the rates of stress urinary incontinence (SUI) and erectile dysfunction (ED), and of associated bother, in men with no evidence of prostate cancer who participated in a prostate cancer-screening event. SUBJECTS AND METHODS A cohort of 366 men with no established diagnosis of prostate cancer completed a questionnaire addressing SUI, ED and associated bother. Socio-economic status and presence of comorbidities were also examined. RESULTS The mean (range) age of the men was 54.8 (33-80) years; 90% of the men (271) had no SUI, and 76% (231) reported no urinary bother. Conversely, 62% (189) reported some degree of ED and 27% (82) some degree of sexual bother. Urinary bother (P < 0.001), erectile function (P < 0.001), and sexual bother (P < 0.02) were associated with age. Of all the men, 36% had one or more comorbidities. Men with one or more comorbidities had worse erectile function than those men with no comorbidity (P < 0.05). CONCLUSION Few studies address normative values of SUI and ED rates in men with no established diagnosis of prostate cancer. We quantified the rate of SUI and it was practically negligible. Conversely, some degree of ED affected most of the present screened population. These data may be used as baseline references to evaluate the magnitude of functional and bother detriments after various prostate treatments.

Abstract
AIM We assessed the team approach in reducing the learning curve during our 2-year experience transiting from open to robot-assisted laparoscopic radical prostatectomy (rLRP). METHODS A team of three urologists progressed through assistant phase to console phase to obtain competency in robotic prostatectomy. One hundred patients underwent rLRP by this team using the da Vinci robotic surgical system from 1 February 2003 to 15 May 2005. RESULTS The immediate perioperative outcome was divided into three corresponding time frames and the results demonstrated gradual improvement in outcome parameters. The mean set-up time and dissection time were 24+/-14 min and 182+/-52 min, respectively. The mean perioperative blood loss was 272+/-240 mL, and 7% of patients (n=7) required blood transfusion. The mean duration of bladder catheterization was 8.4+/-4.1 days, and mean hospital stay was 2.9+/-1.6 days. There was no perioperative mortality or conversion to open radical prostatectomy. Major complications (4%) included urethrovesical leak requiring re-operation, postoperative cerebrovascular accident, and transient ureteric obstruction. Minor complications (7%) included minor urethrovesical leak, bladder neck stenosis, and urinary tract infection. Mean follow up was 6.6+/-5.0 months. Pathological assessment showed pT2 disease in 55% and pT3 in 45% of specimens. CONCLUSIONS A team-based approach to robot-assisted LRP helped to reduce the learning curve of the procedure for individual surgeons and continued to show significantly lower perioperative blood loss, transfusion requirements and postoperative pain compared to open radical retropubic prostatectomy.

Abstract
Herpes simplex virus (HSV) oncolytic gene therapy is a promising treatment modality against cancer. We have demonstrated that androgen-induced cellular changes enhance oncolytic viral replication and improve efficacy in the treatment of androgen-dependent prostate cancer cell line. Imaging of changes in 2-deoxy-2-[F-18]fluoro-D-glucose (FDG) uptake by positron emission tomography (PET) is a sensitive method of detecting altered cellular metabolism involved in cancer therapy. We therefore hypothesized that FDG-PET can predict tumor response to oncolytic HSV therapy. In this study, androgen increased cell kill (74%) in vitro and enhanced viral yield (2.4-fold) in vivo following HSV therapy. This enhanced efficacy was predicted by high FDG accumulation in intact animals compared to low FDG uptake following orchiectomy (p = 0.002). This proof-of-concept study provides the mechanistic basis for selecting patients for targeted oncolytic viral therapy by means of a noninvasive molecular imaging method in the treatment of prostate cancer.

Abstract
OBJECTIVES Radical retropubic prostatectomy is the major procedure for curing early stage prostate cancer. In this retrospective study we valued the complications of this surgery and its evolution in time, as well as the efectiveness of the urinary incontinence preservative treatment in the recovery of urinary continence. MATERIALS AND METHODS During the period between december of 1998 to january of the 2005 we have treated 168 patients suffering prostatic adenocarcinoma clinically confined to the gland by means of retropubic radical prostatectomy. We removed the vesical catheter the fourteenth day of the postoperative and made a clinical monitoring the first, third and sixth month after the surgery, and thereafter every six months. RESULTS Of the 168 patients who underwent clinical surgery, 15% required postoperative blood transfusion in the immediate postoperative. Other complications, with a lower incidence, were the intestinal perforation, surgical wound infection and the haematoma. The most frequent delayed complications we registered were erectile dysfunction, observed in 164 patients (98%), micturition alterations in 32 patients (19%) and intestinal alterations in approximately 11%. Among the micturitional alterations found, the most frequent (64%) was the Urinary Incontinence (UI). However, most of them were of minor importance (34%) and all improved during the first six months after the surgery. We advised patients with minor and moderate UI to perform pelvic floor muscle training, being very useful since they allowed to anticipate the recovery of continence. CONCLUSIONS Radical prostatectomy continues to be the most effective treatment for the non spared prostate cancer, in spite of the associated morbidity. The IU is the main factor for the high standard of living these patients. Despite the number of patients with UI being so high, most cases are moderate and minor and may improve with pelvic floor muscle training. Hence, this is a significant tool to tackle this illness, whether in connection with the use of absorbent, the pharmacologic therapy or the use of penile collectors.

Abstract
The neurovascular bundle of the prostate and cavernosal nerves have been used to describe the same structure ever since the publication of the first studies on the neuroanatomy of the lower urogenital tract of men, studies that were prompted by postoperative complications arising from radical prostatectomy. In urological surgery every effort is made to preserve or restore the neurovascular bundle of the prostate to avoid erectile dysfunction (ED). However, the postoperative potency rates are yet to be satisfactory despite all advancements in radical prostatectomy technique. As the technology associated with urological surgery develops and topographical studies on neuroanatomy are cultivated, new observations seriously challenge the classical teachings on the topography of the neurovascular bundle of the prostate and the cavernosal nerves. The present review revisits the classical and most recent data on the topographical anatomy of the neurovascular bundle of the prostate and cavernosal nerves and their implications on radical prostatectomy techniques.

Abstract
The objective of this study was to study the effect of early pelvic floor re-education on the degree and duration of incontinence and to evaluate the results of radical retropubic prostatectomy (RRP) performed in a non-teaching hospital. This is a non-randomised study. From March 2000 to November 2003, 57 consecutive men, who underwent RRP for localized prostate cancer, participated in a pelvic floor re-educating program. Continence was defined as a loss of no more than 2-g urine on the 24-h pad test and no use of pads. The 24-h pad test was performed once in every 4 weeks until the patient indicated that he was continent. Diurnal and nocturnal continence was achieved after 1, 2, 3, 6 and 12 months post catheter removal in 40, 49, 70, 86 and 88% of all men, respectively. Comparison of our results with current literature suggest that the time period towards continence after a RRP can be shortened relevantly if pelvic floor re-education is started directly after catheter removal.

Abstract
Radical prostatectomy for the treatment of prostate cancer can be performed by various techniques using a retropubic, perineal, or laparoscopic approach. Besides tumor control, the postoperative urinary continence rates and potency rates impact patients' quality of life after radical prostatectomy. This paper shows the results of our own center and compares the data in the literature regarding functional results of radical prostatectomy with respect to various operative techniques.

Abstract
The aim of this work was to evaluate variables that predict time to pad-free urinary continence after anatomical radical prostatectomy (ARP). Sixty consecutive prostate cancer patients who underwent ARP by one surgeon were studied. Pad-free urinary continence was prospectively determined by patient interviews and confirmed on physical examination and by the urinary domain of the Extended Prostate Inventory Composite (EPIC) Health Related Quality of Life questionnaire. A time-dependent Cox multivariate regression analysis was performed to determine which variables significantly correlated with time to pad-free urinary continence. Increasing prostate size (cc), increasing prostate urethral length (cm) and surgical technique (wide excision of the neuro-vascular bundle) correlated with a significantly (P<0.05) prolonged time to achieve pad-free urinary continence. In conclusion, prostate size and surgical technique were the most useful variables in predicting time to pad-free urinary continence after ARP.

Abstract
OBJECTIVES To describe the role of surgery in the treatment of organ-confined prostate cancer and advanced prostate cancer. DATA SOURCES Journals, textbooks, and personal communication. CONCLUSIONS Radical prostatectomy plays a possible role in curing those patients with disease confined to the prostate. Bilateral orchiectomy plays a palliative role for patients with advanced disease. IMPLICATIONS FOR NURSING PRACTICE This article provides nurses with the knowledge needed to teach patients about how the surgery is performed, the associated complications, and the likelihood of cancer control.
