Oxybutynin ER to Promote Early Continence Recovery After Robotic Prostatectomy: A Randomized Controlled Trial

Summary

The goal of this double-blind, randomized, placebo-controlled study is to evaluate whether oxybutynin chloride extended-release tablets can improve early continence recovery after robot-assisted radical prostatectomy (RARP) in patients with localized prostate cancer. The main questions it aims to answer are: \[Does oxybutynin chloride improve continence recovery after RARP compared to a placebo?\] \[What are the predictors of continence recovery?\] Researchers will compare the treatment group (oxybutynin chloride 10 mg/day) with the control group (placebo) to assess differences in continence outcomes. Participants will: \[Take the assigned medication (oxybutynin chloride or placebo) daily for 1-3 months until continence recovery.\] \[Complete surveys (e.g., IPSS, IIEF, ICIQ) at several time points post-surgery, including before surgery, 10 days after Foley catheter removal, and up to 12 months.\] \[Record any adverse events or concomitant medication use.\] Safety and tolerability will be monitored, and statistical analyses will determine the efficacy and predictors of continence. The study adheres to ethical principles, local regulations, and GCP guidelines.
