Abstract

Abstract: Objective: Urinary incontinence (UI) is one of the most common complications of radical prostatectomy (RP). Impaired urethral sphincter function is generally considered to be the most important contributing factor for UI; however, the mechanism of onset and recovery of urinary continence has not been fully elucidated. The objective of this research was to evaluate preoperative functional urethral length (FUL) and maximum urethral closure pressure (MUCP) as early continence recovery predictors after open retropubic RP (ORRP).Methods: The research was conducted on a group of 43 patients with localized prostate cancer (PCa) in the period from July 2019 to May 2021. The urodynamic method of urethral pressure profile (UPP) was used to assess FUL and MUCP, and correlate with the postprostatectomy continence recovery. The severity of UI and bothersome were assessed using fully validated International Consultation on Incontinence Questionnaire – Urinary Incontinence Short Form (ICIQ‐UI SF) and number of pads used in 24 h. Patients were interviewed about the use of urinary pads and asked to fill out the ICIQ‐UI SF before and 2, 8, 16 and 24 weeks after ORRP.Results: The median value of FUL (mm) and MUCP (cmH2O) was 69 (28–94) and 76 (16–223), respectively. Correlation and linear regression showed a statistically significant negative correlation between preoperative values of FUL and MUCP with ICIQ symptom score and the number of pads used per day at the four observed time intervals ( p < 0.05). Such a result showed that patients with higher preoperative FUL and MUCP values were more likely to recover urinary continence earlier. A value of 65 mm for FUL and 80 cmH2 O for MUCP proved to be the cut‐off values for continence recovery in 24 weeks after ORRP.Conclusion: Preoperatively evaluated FUL and MUCP seem to be valuable prognostic factors for early continence recovery after ORRP. Further investigation on a larger patient cohort is needed to evaluate the role of UPP in the preoperative management of patients with PCa.
