Purpose Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Few studies have explored the relationships and differences between stress urinary incontinence (SUI) and urgent urinary incontinence (UUI) after RARP. This study aimed to investigate the occurrence rates and risk factors of UUI and SUI in short term after RARP. Methods We prospectively included prostate cancer patients who underwent RARP by a single surgeon. Demographics, lower urinary tract function, oncology, and follow-ups were recorded. Occurrence rates and risk factors of UUI and SUI within 3 months after catheter withdrawal were calculated. Results The study cohort included 363 subjects with a mean age of 66.05 years. The median preoperative International Prostate Symptom Score (IPSS) was 14 (range 0–35), and the median Overactive Bladder Symptom Score (OABSS) was 3 (range 0–14). The occurrence rate of UUI and SUI at 3 months after catheter withdrawal was 8.5% (31/363) and 15.2% (55/363). Nearly all patients with UUI also had SUI. Diabetes history and high OABSS before RARP were independent risk factors for UUI, especially within 1 month after catheter withdrawal. The Gleason Score was an independent risk factor for SUI at 3 months after catheter withdrawal. Additionally, UUI but not SUI might be an influencing factor for decision-making regarding postoperative radiotherapy. Conclusion The occurrence rate of SUI after RARP was persistently higher than that of UUI. Nearly all of the patients with UUI simultaneously had SUI. The risk factors of UUI and SUI after RARP were absolutely different.
