[Urinary continence after radical retropubic prostatectomy: a modification in the technique of apical dissection]

Urinary incontinence impairs the quality of life for patients following radical prostatectomy. We retrospectively reviewed the records of 36 patients who underwent radical retropubic prostatectomy between 1987 and 2002, and achieved the time from operation until urinary continence. A modification in the technique of apical dissection was introduced in 1999 and applied in 12 cases of consecutive radical prostatectomy. The principles for this technique were based on sharp division of the dorsal vein complex, continuous suturing cut edges of lateral pelvic fascia, and anterior anastomotic sutures including lateral pelvic fascia as well as urethra and bladder neck. None of the patients undergoing the new technique used pads at 6 months. With introduction of this technique, the rate of continence at 12 months increased from 58.3 to 100.0%. Our results suggest that the surgical technique of apical dissection is an important factor associated with postprostatectomy in continence.
