• INTRODUCTION:

  To clarify the efficacy and safety of propiverine hydrochloride for incontinence after robot-assisted laparoscopic prostatectomy (RALP)/laparoscopic radical prostatectomy (LRP), along with changes in the urethral pressure profile (UPP) and quality of life in patients treated with propiverine hydrochloride.

  MATERIALS AND METHODS:

  In this randomized, comparative study, 104 patients who were aware of urinary incontinence after RALP or LRP were assigned to receive propiverine hydrochloride (treatment group) or not (controls). Pad test results, International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) scores, and UPP results [including maximum urethral closure pressure (MUCP) and functional urethral length (FUL)], were recorded immediately and at 6 months postoperatively.

  RESULTS:

  No serious intraoperative complications or adverse events were caused by propiverine hydrochloride. The pad-test negative rate was significantly greater in the treatment group than in controls (89.1% vs. 73.2%, p = 0.044). Changes in ICIQ-SF scores and MUCP were significantly greater in the treatment group than in controls [-6.5 vs. -4.5 points (p = 0.021), and +49.5 vs. +28.7 mmHg (p = 0.038), respectively]. FUL change did not significantly differ between groups [+4.5 vs. +3.8 mm (p = 0.091)]. In univariate logistic regression analyses, body mass index (BMI), MUCP, and treatment with propiverine hydrochloride were significantly associated with continence status. In multivariate analyses, BMI and MUCP were independently associated with continence status [odds ratio (OR), 1.266; 95% confidence interval (CI), 1.047–1.530 (p = 0.015), and OR, 0.986; 95% CI, 0.973-0.999 (p = 0.042), respectively].

  CONCLUSIONS:

  Treatment with propiverine hydrochloride alleviated urinary incontinence while improving patient symptoms and quality of life after RALP or LRP.
