Novel use of the capio urethral anastomotic suturing device: a 50-case assessment

Robotic laparoscopic assisted prostatectomy (RALP) has become the predominant technique for prostatectomy despite significant expense and no robust evidence supporting better cancer control, erectile function, or continence. Several studies have demonstrated lower bladder neck contracture (BNC) rates with RALP, believed to be related to improved visualization and control of the urethrovesical anastomosis. We evaluated the Capio™ radical prostatectomy (RP) suture capturing device for improving anastomotic precision during urethrovesical anastomosis in open radical prostatectomy.

We performed a retrospective review on a single-surgeon series of 50 consecutive patients undergoing radical retropubic prostatectomy (RRP) with utilization of the Capio™ RP device at an academic hospital (February 2010 to May 2012). Patient demographics, pathology, and outcomes data including rates of anastomotic leak, BNC, erectile function, and continence were collected.

Mean age of patients at the time of procedure was 60.4 ± 6.43 years. Patients were stratifed by D'Amico criteria into low (14.3%), intermediate (67.4%), and high (18.4%) risk groups. Mean follow-up for all patients was 13.1 ± 7.29 months. No patients were diagnosed with BNC within 90 days after surgery. Two patients (4%) were subsequently diagnosed and treated for BNC, one of whom was asymptomatic prior to diagnosis.

Utilizing the Capio™ RP device during RRP, we were able to achieve a BNC rate equivalent to rates reported for RALP. Use of the Capio™ RP device appears to be a cost-effective method for improving RRP urethrovesical anastomotic results.
