Introduction: Post-void dribbling (PVD) is a potential consequence of urethroplasty. Our objective is to examine the impact of urethroplasty on PVD and factors associated with de novo PVD.
Methods: From 2011-2018, patients were enrolled in a prospective single-center study. PVD was assessed using a 5-point scale in response to, “After urinating, do you have post-urination dribbling or leakage of urine?” pre-operatively and 6 months post-operatively. Answers included “Never” (1), “Occasionally” (2), “Sometimes” (3), “Most of the Time” (4), or “All of the Time” (5). Significant PVD was considered a response of 3-5. Wilcoxon signed-rank test was used to compare pre- and post-operative incidence of PVD. Multivariate binary logistic regression was used to determine the association between new onset PVD and clinical factors.
Results: 384 patients completed the study. Pre-operatively 46.9% (180) of patients reported PVD vs. 39.8% (153) post-operatively (p=0.01). Compared to pre-operative status, 25.0% (96) of patients reported improvement in PVD and 57.0% (219) reported no change but 18.0% (67) experienced de novo PVD. On multivariate binary logistic regression, urethroplasty technique was associated with de novo PVD (p=0.05). Patients undergoing anastomotic urethroplasty were less likely to report de novo PVD (O.R.0.33,95%CI 0.13-0.83; p=0.02) compared to onlay or staged techniques. No other factor was associated with de novo PVD including age (p=0.59), stricture length (p=0.71), location (p=0.50), etiology (p=0.59), failed endoscopic treatment (p=0.18), previous urethroplasty (p=0.55) or stricture recurrence (p=0.78). De novo PVD was not associated with patient dissatisfaction (10.1% versus 7.6%;p=0.49).
Conclusion: PVD is common in patients with urethral stricture and there is an overall improvement after urethroplasty but 18.0% of patients will experience de novo PVD. Patients undergoing anastomotic urethroplasty are less likely to experience de novo PVD.
