Vesicourethral anastomosis including rhabdosphincter in retropubic radical prostatectomy: Technique and results.

Objective: Retropubic radical prostatectomy (RRP) is still widely used in clinical practice in localized prostate cancer because of its high oncological success. The aim of this study was to define the continence status in patients where rhabdosphincter was included in the vesicourethral anastomosis.

Materials And Methods: Between November 2004 and September 2010, 90 cases who underwent RRP by the same surgeon in our clinic were taken into the study. In all cases vesicourethral anastomosis was performed include the rhabdosphincter. The anastomosis was performed with mean 2.9 (0-7) interrupted no 2-0 vicryl sutures, depending on the angulation of symphysis pubis and pelvic cavity. Pad test was performed to all patients at 1, 3, 6 and 12 months postoperatively. We defined patients as 'continent' when they no need pad, as 'mild incontinence' when they use only one pad daily, as 'moderate incontinence' when they use two or three pads daily and as 'severe incontinence' when they use more than three pads daily.

Results: Preoperative total PSA value was 12.2 ng/ml (range: 2.7-84 ng/ml). Preoperative prostate biopsy results were found that Gleason scores were 5, 6, 7 and 8 in 7, 53, 21, 9 patients, respectively. Mean operation and urethral catheter removal time was 103 minutes (60-200) and 14,6 days (9-28), respectively. Mean hospital stay was 4.6 days (2-20). According to results of postoperative pad tests, 38 (42.2%), 48 (53.3%), 55 (61.1%) and 75 (83.3%) patients were defined as continent in first, third, sixth and twelfth months, respectively.

Conclusions: We think that, our novel technique of vesicourethral anastomosis in standard RRP provides more optimal urethral position during fixation of pelvic floor and urethra, protect caudal retraction, preserve functional urethral length. Also strong full thickness stitch on urethra provides better urinary continence by hanging urethra in our patients. Although our early continence rate is better, our long term continence rate is similar to literature.
