Are We Improving Erectile Function Recovery After Radical Prostatectomy? Analysis of Patients Treated over the Last Decade.

ABSTRACT: BACKGROUND:The last decade has seen several advances in radical prostatectomy (RP) technique and post-RP care that are relevant to erectile function (EF) recovery. OBJECTIVE:We examined whether these practice changes have led to observed improvements in EF rates over time. DESIGN, SETTING, AND PARTICIPANTS:We identified 2364 patients treated with either open or minimally-invasive RP at a single academic center in 2008-2015. To mitigate confounding by the surgical learning curve, only patients treated by surgeons who performed at least 100 procedures were considered. INTERVENTION:EF before and after RP was assessed by the International Index of Erectile Function 6 (IIEF-6), with recovery defined as IIEF-6 ?24. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS:We analyzed EF recovery rates of patients treated with bilateral nerve-sparing surgery and free from adjuvant/salvage treatment at the time of EF assessment. Local polynomial regression analyses explored changes in the outcomes over time. Linear and logistic regression analyses were used to estimate the influence of year of surgery on baseline variables and EF recovery. RESULTS AND LIMITATIONS:We observed a significant decrease over time of the EF recovery rates at both 12 and 24mo post-RP (all p=0.01). However, patient's age at surgery increased over time (mean increase of 0.5 per year; p<0.01), with a resultant increase in risk of comorbidity (odds ratio [OR]=1.1, 95% confidence interval [CI]: 1.02-1.15; p=0.008) and thus decrease in baseline IIEF-6 score (0.35 points per year; p=0.0003). After accounting for baseline and pathological characteristics, urinary function, and type of surgery in a multivariable analysis, year of surgery was not associated with EF recovery (12mo: OR=0.97, 95% CI: 0.91-1.03, p=0.4; 24mo: OR=0.97, 95% CI: 0.91-1.03, p=0.3). CONCLUSIONS:Findings from a high-volume center suggest that, despite the advancements in surgical and postoperative care, EF outcomes after RP have not improved over the last decade. Additional strategies are required to improve EF recovery after RP. PATIENT SUMMARY:The probability of regaining potency after surgery for prostate cancer did not improve over the last decade; more efforts are needed to improve patient's care after radical prostatectomy.

Project description:BackgroundIntrafascial nerve-sparing prostatectomy has been currently applied based on the updated anatomic understanding of periprostatic cavernous nerves, in order to provide patients better postoperative recovery of continence and potency. The aim of our study is to perform a pooled analysis of available literatures regarding the functional outcomes following intrafascial nerve-sparing technique.MethodsThe authors performed database searches of articles published till October 2017 on PubMed using following keywords across the "title" and "abstract" field of the records: intrafascial, veil, curtain dissection, high anterior release, incremental nerve sparing, and radical prostatectomy. Fulfilled papers were screened and data were extracted independently by 3 reviewers. Main outcome was the postoperative continence and potency rate stratified by follow-up durations. Both 1-arm and comparative meta-analyses were performed and meta-regression models were conducted to evaluate the confounding factors.ResultsUsing the electronic search strategy, a total of 71 records were retrieved and 20 studies were finally included, of which 6 were surgical series and 14 were controlled studies. Our 1-arm meta-analysis summarized the pooled continence rates after intrafascial prostatectomy were 59.4%, 76.2%, 89.9%, and 92.2% at postoperative follow-up of 1, 3, 6, and 12 months, respectively. Regardless of the variance in potency definition, the pooled potency rates after intrafascial prostatectomy were 42.2%, 54.2%, and 72.2% at 3, 6, and 12 months, respectively. Comparative analysis showed that the intrafascial group offered better continence rates at 1, 3, and 6 months with an odds ratio (OR) of 2.38 (95% confidence interval [CI]: 1.73-3.26), 1.82 (95% CI: 1.18-2.82), and 2.19 (95% CI: 1.43-3.34) as compared with the interfascial group. Moreover, potency rate in the intrafascial group was higher at 12 months than in the interfascial group, with an OR of 2.44 (95% CI: 1.35-4.42).ConclusionBased on the limited evidence, our study demonstrated that intrafascial nerve-sparing prostatectomy could provide patients with earlier recovery of continence and better erectile function compared with conventional interfascial approach, but physiological mechanisms about this technique still need further study.

Project description:To examine the effect of penile vibratory stimulation (PVS) in the preservation and restoration of erectile function and urinary continence in conjunction with nerve-sparing radical prostatectomy (RP).The present study was conducted between July 2010 and March 2013 as a randomized prospective trial at two university hospitals. Eligible participants were continent men with an International Index of Erectile Function-5 (IIEF-5) score of at least 18, scheduled to undergo nerve-sparing RP. Patients were randomized to a PVS group or a control group. Patients in the PVS group were instructed in using a PVS device (FERTI CARE(®) vibrator). Stimulation was performed at the frenulum once daily by the patients in their own homes for at least 1 week before surgery. After catheter removal, daily PVS was re-initiated for a period of 6 weeks. Participants were evaluated at 3, 6 and 12 months after surgery with the IIEF-5 questionnaire and questions regarding urinary bother. Patients using up to one pad daily for security reasons only were considered continent. The study was registered at http://clinicaltrials.gov/ (NCT01067261).Data from 68 patients were available for analyses (30 patients randomized to PVS and 38 patients randomized to the control group). The IIEF-5 score was highest in the PVS group at all time points after surgery with a median score of 18 vs 7.5 in the control group at 12 months (P = 0.09), but the difference only reached borderline significance. At 12 months, 16/30 (53%) patients in the PVS group had reached an IIEF-5 score of at least 18, while this was the case for 12/38 (32%) patients in the control group (P = 0.07). There were no significant differences in the proportions of continent patients between groups at 3, 6 or 12 months. At 12 months 90% of the PVS patients were continent, while 94.7% of the control patients were continent (P = 0.46).The present study did not document a significant effect of PVS. However, the method proved to be acceptable for most patients and there was a trend towards better erectile function with PVS. More studies are needed to explore this possible effect further.

Project description:Radical prostatectomy (RP) offers a good long-term cancer control for clinically localized prostate cancer. However, complications such as erectile dysfunction and substantial decreases quality of life of the afflicted men and their sexual partners. Identification of pre-, per-, and postoperative factors that correlate with poor postoperative erectile status must be considered an important step to improving penile rehabilitation.To describe postoperative erectile function after RP in a Danish cohort.The medical records of 1,127 patients undergoing RP from March 2003 through September 2014 were reviewed retrospectively with a 12-month follow-up after surgery. In all, 704 patients fulfilling the inclusion criteria were included in the final analysis. Recovery was defined as self-reported erection sufficient for intercourse (ESI) with or without usage of erectile aids.Subjective reporting of erectile function and usage erectile aids 12 months after RP.ESI with or without erectile aids was reported by 226 men (32.1%), among whom 109 (48.2%) required erectile aids. Erectile dysfunction (ED) was reported by 478 men (67.9%) and by 121 (25.3%) despite use of erectile aids. Of men with ED, 155 (22%) stated not being interested in penile rehabilitation, 26 (3.7%) stated not having resumed their sex life 12 months after RP, and 241 (34.2%) had ED and were unsatisfied with the condition. We found that 134 of 445 men (30.1%) who underwent non-nerve-sparing RP had ESI 12 months after RP. Age older than 60.5 years, a high body mass index, comorbidity, and a high American Society of Anesthesiologists score were negative predictors of erectile function 12 months after RP.Twelve months after RP, 32.1% of men had ESI; half these men required the use of erectile aids. Age older than 60.5 years, a high body mass index, comorbidity, and a high American Society of Anesthesiologists score were negative predictors for ED 12 months after RP.

Project description:Understanding predictors for the recovery of erectile function (EF) after nerve-sparing radical prostatectomy (nsRP) might help clinicians and patients in preoperative counseling and expectation management of EF rehabilitation strategies.To describe the effect of potential predictors on EF recovery after nsRP by post hoc decision-tree modeling of data from A Study of Tadalafil After Radical Prostatectomy (REACTT).Randomized double-blind double-dummy placebo-controlled trial in 423 men aged <68 yr with adenocarcinoma of the prostate (Gleason ?7, normal preoperative EF) who underwent nsRP at 50 centers from nine European countries and Canada.Postsurgery 1:1:1 randomization to 9-mo double-blind treatment with tadalafil 5mg once a day (OaD), tadalafil 20mg on demand, or placebo, followed by a 6-wk drug-free-washout, and a 3-mo open-label tadalafil OaD treatment.Three decision-tree models, using the International Index of Erectile Function-Erectile Function (IIEF-EF) domain score at the end of double-blind treatment, washout, and open-label treatment as response variable. Each model evaluated the association between potential predictors: presurgery IIEF domain and IIEF single-item scores, surgical approach, nerve-sparing score (NSS), and postsurgery randomized treatment group.The first decision-tree model (n=422, intention-to-treat population) identified high presurgery sexual desire (IIEF item 12: ?3.5 and <3.5) as the key predictor for IIEF-EF at the end of double-blind treatment (mean IIEF-EF: 14.9 and 11.1), followed by high confidence to get and maintain an erection (IIEF item 15: ?3.5 and <3.5; IIEF-EF: 15.4 and 7.1). For patients meeting these criteria, additional non-IIEF-related predictors included robot-assisted laparoscopic surgery (yes or no; IIEF-EF: 19.3 and 12.6), quality of nerve sparing (NSS: <2.5 and ?2.5; IIEF-EF: 14.3 and 10.5), and treatment with tadalafil OaD (yes and no; IIEF-EF: 17.6 and 14.3). Additional analyses after washout and open-label treatment identified high presurgery intercourse satisfaction as the key predictor.Exploratory decision-tree analyses identified high presurgery sexual desire, confidence, and intercourse satisfaction as key predictors for EF recovery. Patients meeting these criteria might benefit the most from conserving surgery and early postsurgery EF rehabilitation. Strategies for improving EF after surgery should be discussed preoperatively with all patients; this information may support expectation management for functional recovery on an individual patient level.Understanding how patient characteristics and different treatment options affect the recovery of erectile function (EF) after radical surgery for prostate cancer might help physicians select the optimal treatment for their patients. This analysis of data from a clinical trial suggested that high presurgery sexual desire, sexual confidence, and intercourse satisfaction are key factors predicting EF recovery. Patients meeting these criteria might benefit the most from conserving surgery (robot-assisted surgery, perfect nerve sparing) and postsurgery medical rehabilitation of EF.ClinicalTrials.gov, NCT01026818.

Project description:BackgroundAlthough the concept of penile rehabilitation after radical prostatectomy (RP) has been advocated for decades, there is little definitive evidence regarding its utility or the best strategy to optimize patient outcomes.AimThe goal of this study is to analyze the ability of 3 different pharmacological strategies to preserve the ability of men to achieve spontaneous (non-medication assisted) erections after bilateral nerve-sparing RP.MethodsThis IRB- and FDA-approved study studied penile rehabilitation in a 3-arm fashion with a target enrollment of 200 patients. (i) Control arm: nightly placebo with sildenafil 100 mg on demand for sexual relations (up to 6 pills/month); (ii) nightly sildenafil arm: nightly sildenafil 50 mg and sildenafil 100 mg on demand for sexual relations (up to 6 pills/month); (iii) combination therapy arm: nightly sildenafil 50 mg (5 nights/week) plus intracavernosal injections twice/week. Inclusion criteria included bilateral nerve-sparing surgery, normal serum total testosterone, and good preoperative baseline erectile function as measured by the erectile function domain score of the IIEF (EFD) (≥24). Patients were followed with a medication use diary and the IIEF questionnaire at 6 weeks, 3 m, 6 m, 12 m, 18 m and 24 m.OutcomesA difference was seen in the IIEF-EFD scores between the 3 groups at 24 months after RP. Secondary end points include the time to return of spontaneous functional erections, the time for patients to respond to oral erectogenic therapy, and the proportion of patients who have normalization of their IIEF-EFD scores.ResultsThe study was interrupted because of failure to recruit the target study population in a reasonable timeframe. A total of 76 subjects with median age of 57 (IQR: 51, 63) years and mean IIEF-EFD of 29 (IQR: 27, 30) were initially randomized, but at 24 months, the sample sizes by group were (i) n = 4; (ii) n = 18; and (iii) n = 10, with median IIEF-EFD 24 (IQR: 18, 28), 24 (IQR: 18, 28), and 21 (IQR: 9, 26), respectively. There was no statistical difference among the groups in the final analysis.Clinical implicationsDefinitive evidence for the ability of different pharmacological rehabilitation strategies to improve long-term EF outcomes might never be available.Strengths & limitationsThis was a well-designed randomized and 3-arm designed trial intended to provide decisive evidence regarding the utility of penile rehabilitation. Failure to recruit the target population is the main limitation.ConclusionThe limited number of patients in the present trial precludes definitive interpretation. However, results indicate how challenging it is to conduct true rehabilitation studies. Miranda EP, Benfante N, Kunzel B, et al.
