BACKGROUND Urinary continence recovery after radical prostatectomy is a major issue even in the robotic era. Surgical techniques aimed at improving earlier return to continence are continuously sought. OBJECTIVE To describe our novel surgical technique of urethral fixation during robot-assisted radical prostatectomy (RARP) and to assess early urinary continence recovery and perioperative complications. DESIGN, SETTING, AND PARTICIPANTS A prospective, single-center, single-surgeon cohort of 70 consecutive patients undergoing RARP between January and December 2019 was analyzed. A study group of 35 patients operated on with the urethral fixation technique was compared with a control group of 35 patients receiving standard vesicourethral anastomosis. SURGICAL PROCEDURE Urethral fixation versus standard vesicourethral anastomosis during RARP was evaluated. In the study group, the urethral stump was fixed to the dorsal median raphe posteriorly and to the medial portion of the levator ani muscle posterolaterally. The same posterior musculofascial reconstruction incorporating the vesicourethral anastomosis was performed in both groups. MEASUREMENTS Urinary continence recovery, perioperative complications, operating room time, and estimated blood loss were recorded and compared between the two groups. RESULTS AND LIMITATIONS The two groups were comparable with regard to all demographic, clinical, and pathological variables. Recovery of urinary continence at 3 mo after catheter removal was reported by 34 (97.1%) patients in the study and 28 (80%) patients in the control group (p = 0.02). Patients in the study group reported significantly higher rates of urinary continence even at 1 wk and 1 mo after catheter removal compared with the control group (68.6% vs 45.7%, p = 0.04, and 80% vs 54.3%, p = 0.04, respectively). No differences were observed in operating room time (p = 0.7) or estimated blood loss (p = 0.65). Ninety-day postoperative complications were observed in one (2.9%) patient in the study and in four (11.4%) in the control group (p = 0.3). The main limitation is the nonrandomized comparison of relatively small cohorts. CONCLUSIONS In our study, we observed a significant improvement in early urinary continence recovery, with no increase in operating room time or perioperative complications, using the novel urethral fixation technique compared with the standard vesicourethral anastomosis during RARP. PATIENT SUMMARY We describe our novel surgical technique of urethral fixation during robot-assisted radical prostatectomy. Compared with the standard technique, utilization of our technique was found to be associated with an improved early recovery of urinary continence, with no increase in operating room time or perioperative complications.
