Abstract:
OBJECTIVE:To evaluate urinary continence recovery time and risk factors of urinary continence recovery after robot-assisted laparoscopic radical prostatectomy (RARP).
METHODS:From January 2019 to January 2021, a consecutive series of patients with localized prostate cancer (cT1-T3, cN0, cM0) were prospectively collected. RARP with total anatomical reconstruction was performed in all the cases by an experienced surgeon. Lymph node dissection was performed if the patient was in high-risk group according to the D'Amico risk classification. The primary endpoint was urinary continence recovery time after catheter removal. Postoperative and pathological variables were analyzed. Continence was rigo-rously analyzed 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks after catheter removal. Continence was evaluated by recording diaper pads used per day, and all the patients were instructed to perform the 24-hour pad weight test until full recovery of urinary continence. The patient was defined as continent if no more than one safety pad were needed per day, or no more than 20-gram urine leakage on the 24-hour pad weight test. Time from catheter removal to full recovery of urinary continence was recorded, and risk factors influencing continence recovery time evaluated.
RESULTS:In total, 166 patients were analyzed. The mean age of the enrolled patients was 66.2 years, and the median prostate specific antigen (PSA) was 8.51 μg/L. A total of 59 patients (35.5%) had bilateral lymphatic dissection, and 28 (16.9%) underwent neurovascular bundle (NVB) preservation surgery. Postoperative pathology results showed that stage pT1 in 1 case (0.6%), stage pT2 in 77 cases (46.4%), stage pT3 in 86 cases (51.8%), and positive margins in 28 patients (16.9%). Among patients who underwent lymph node dissection, lymph node metastasis was found in 7 cases (11.9%). Median continence recovery time was one week. The number of the continent patients at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 65 (39.2%), 32 (19.3%), 34 (20.5%), 24 (14.5%), and 9 (5.4%). Two patients remained incontinent 24 weeks after catheter removal. The continence rates after catheter removal at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 39.2%, 58.4%, 78.9%, 93.4%, and 98.8%, respectively. Univariate COX analysis revealed that diabetes appeared to influence continence recovery time (OR=1.589, 95%CI: 1.025-2.462, P=0.038). At the end of 48 hours, 4 weeks, 12 weeks, and 24 weeks after catheter removal, the mean OABSS score of the continent group was significantly lower than that of the incontinent group.
CONCLUSION:RARP showed promising results in the recovery of urinary continence. Diabetes was a risk factor influencing continence recovery time. Bladder overactive symptoms play an important role in the recovery of continence after RARP.
