Continence outcomes following robotic radical prostatectomy: Our experience from 150 consecutive patients

INTRODUCTION: Urinary continence is an important outcome parameter after robot assisted radical prostatectomy (RARP). We evaluated the continence outcomes following RARP using a double-layered urethrovesical reconstruction. MATERIALS AND METHODS: One hundred fifty consecutive patients undergoing RARP and double-layered urethrovesical reconstruction were prospectively studied for preoperative, intraoperative and post operative parameters. Key points followed during surgery were: Minimal dissection of sphincteric complex, preservation of puboprostatic ligament, selective ligation of deep venous complex and both posterior and anterior reconstruction using the Von Velthoven stitch. Intraoperative bladder fill test was done at the end of anastomosis to rule out urine leak. Check cystogram was done prior to catheter removal in the outpatient department. Patients were subsequently followed at regular intervals regarding the status of urinary continence. All patients irrespective of adjuvant therapy were included in the analysis. RESULTS: The mean age was 64 years (standard deviation ± 6.88), and mean serum PSA was 20.2 ng/ml. The mean BMI was 25.6 (SD: ±3.84). The mean prostate weight was 44.09 gm (range 18-103 gm, SD: ±15.59). Median days to catheter removal after surgery was 7 (range 4-14 days) days. Cystographically determined urinary leaks were seen in two patients. Urine leak was managed by delaying catheter removal for 1 week. Minimum 6 month follow up was available in 126 patients. ‘No pad’ status at 1 week, 1 month, 3 months, 6 months and 1 year was 15.1%, 54.9%, 78%, 90.5% and 94.1%, respectively. CONCLUSION: Excellent continence outcomes are observed in patients undergoing double-layered urethrovesical reconstruction.
