Validation of "patient-reported outcomes via online questionnaire" as a urinary continence assessment and quality improvement tool following radical prostatectomy.

BACKGROUND: Securing reliable data on functional outcomes following radical prostatectomy (RP) is paramount to patient follow-up and management. OBJECTIVE: To validate an email-based patient-reported outcomes tracking system in assessing pad-free continence rates and time-to continence recovery following RP. PATIENTS AND METHODS: 483 men undergoing RP by a single surgeon from November 2013 to March 2019 were prospectively assigned to 1 of 3 tracking systems: 1) a preaddressed paper packet containing a pad-free card and daily urinary pad log, (N = 249); 2) an automated email questionnaire, (N = 234) or 3) both (N = 51). Patients tracked electronically received electronic Research Electronic Data Capture surveys 30 days after catheter removal, with up to 3 reminders sent automatically if no response was received within 2 days. Response rates and continence rates were compared in group 1 vs. group 2 via student t-tests; time-to pad-free status was assessed for concordance among men in group 3 via linear regression. RESULTS: Thirty-day response rates in group 1 (paper) vs. group 2 (electronic) were 80.7% (201/249) and 94.0% (220/234), (P < 0.0001); pad-free rates were 64.2% (129/201) and 64.1% (141/220), (P = 0.9847), respectively. Similarly, 1-year response rates in group 1 and 2 were 87.6% (218/249) vs. 94.0% (220/234), (P = 0.0146); pad-free rates were 91.7% (200/218) vs. 96.4% (212/220), (P = 0.0411), respectively. In group 3, time to pad-free continence recovery assessed via Patient Reported Outcomes via Online Questionnaire (PROVOQ) was highly concordant in 89.6% (43/48) of patients ± 5 days (Figure 1, R2 = 0.9893). No significant bias was found for subsequent reporting in either group. CONCLUSION: The use of automated email survey questionnaires via PROVOQ for the assessment of patient-reported post-RP continence recovery facilitates increased response rates, timeliness of response, and accuracy. PROVOQ significantly reduce the labor of tracking continence outcomes, improve quality improvement efforts, and enables surgeons to more clearly differentiates risk of long-term incontinence.

Impact of surgically maximized versus native membranous urethral length on 30-day and long-term pad-free continence after robot-assisted radical prostatectomy.

BACKGROUND: Pelvic multiparametric magnetic resonance imaging (mpMRI)-determined membranous urethral length (MUL) and its surgical maximization have been reported to impact early- and long-term pad-free urinary continence after robot-assisted radical prostatectomy (RARP). OBJECTIVE: The objective of this study was to present evidence (data and video) of important effects on post-RARP continence recovery from both innate mpMRI-assessed and surgical preservation of MUL. DESIGN SETTING AND PARTICIPANTS: Of 605 men undergoing RARP, 580 with complete follow-up were included: Group 1, prior (N = 355), and Group 2, subsequent (N = 225) to technique change of MUL maximization. Effect of innate, mpMRI-assessed MUL on postoperative continence was assessed. SURGICAL PROCEDURE: Before technique change, the dorsal venous complex was stapled before transection of the membranous urethra. After the change, the final step of extirpation was transection of the dorsal venous complex and periurethral attachments, thus facilitating surgical maximization of MUL. MEASUREMENTS: Primary and secondary outcomes for technique change and mpMRI-assessed MUL were both patient-reported 30-day and 1-year pad-free continence after RARP, respectively. RESULTS: Preoperative prostate-specific antigen, age, and disease aggressiveness were significantly higher in Group 2. After technique change and surgical maximization of MUL, 30-day and 1-year pad-free continence were both significantly improved (p < 0.05). In multivariate analysis, maximization of MUL significantly increased the likelihood of both early- and long-term continence recovery. For men undergoing MUL preservation, mpMRI-assessed MUL>1.4 cm also independently predicted higher 30-day (odds ratio: 4.85, 95% confidence interval: 1.24-18.9) and 1-year continence recovery (odds ratio: 11.26, 95% confidence interval: 1.07-118). CONCLUSIONS: Prostatic rotation and circumferential release of apical attachments and maximization of MUL improves continence after RARP. Separately, innate MUL>1.4 cm independently increased 30-day and 1-year continence recovery. PATIENT SUMMARY: Surgeon efforts to maximize MUL during radical prostatectomy are highly encouraged, as maximally preserved MUL likely improves post-RARP continence recovery. In addition, individual patients' mpMRI-assessed MUL (approximately >1.4 cm) independently limits continence recovery.

Testosterone replacement therapy reduces biochemical recurrence after radical prostatectomy.

OBJECTIVE: To evaluate risk of prostate cancer biochemical recurrence (BCR) after radical prostatectomy (RP) in men receiving vs not receiving testosterone replacement therapy (TRT). PATIENTS AND METHODS: A total of 850 patients underwent RP by a single surgeon. All patients had preoperative testosterone and sex hormone-binding globulin levels determined; free testosterone was calculated prospectively. In all, 152 (18%) patients with low preoperative calculated free testosterone (cFT) levels and delayed postoperative sexual function recovery were placed on TRT and proportionately matched to 419 control patients by pathological Gleason Grade Group (GGG) and stage. Rates and time to BCR [two consecutive prostate-specific antigen (PSA) levels of ≥0.2 ng/mL] were compared in univariate and multivariate regression; Cox regression was used to generate a survival function at the mean of covariates. RESULTS: The median follow-up was 3.5 years. There were no statistically significant differences in demographics or general health complications between groups. BCR occurred in 11/152 (7.2%) and 53/419 (12.6%) patients in the TRT and control groups, respectively. In adjusted time-to-event analysis, TRT was an independent predictor of recurrence-free survival. After accounting for GGG, pathological stage, preoperative PSA level, and cFT, patients on TRT were ~54% less likely to recur (hazard ratio 0.54, 95% confidence interval 0.292-0.997). In men destined to recur, TRT delayed time to recurrence by an average of 1.5 years. CONCLUSION: In our experience, TRT after RP significantly reduced BCR and delayed time to BCR. There was no identifiable general health complications associated with TRT. These findings are hypothesis-generating and require confirmation with multi-centred, prospective randomised controlled trials.
