Abstract
Purpose: Although groups at several institutions have long experience with radical perineal prostatectomy (RPP), only few reports of larger series describe associated complications, mostly without reporting management options in detail. We analyzed specific perioperative and postoperative complications of the perineal approach and management strategies thereof. Materials and Methods: The medical records of 630 patients who underwent RPP between January 1997 and May 2003 were retrospectively reviewed in regard to complications and their management. Median followup was 8 months (range 1 to 68). Results: Major complications requiring open surgical intervention were noted in 11 patients (1.7%) for a total surgical revision rate of 2.4% (15 of 630). Two patients with persistent urinary fistula required fistula excision and closure. Two patients with a rectocutaneous fistula needed temporary diverting colostomy. Three patients with a combined urinary and fecal fistula were treated with protective colostomy, fistula excision and the interposition of a tunica vaginalis graft. No further morbidity was observed in these patients. In 7 patients a subvesical hematoma was drained surgically, including 3 mentioned in whom a hematoma expanded into the urethral anastomosis. Minor complications, which could be successfully managed conservatively or with endoscopic interventions only, developed in 124 patients for a total rate of 19.7%. In the long term 9% of the patients experienced postoperative de novo changes in stool habits after RPP but only 2.7% reported distressing anal sphincter incompetence. Conclusions: RPP is a safe and reproducible procedure with low major complication and reintervention rates even in a training center setting with many involved surgeons. A subvesical hematoma should be revised early since it can be the origin of subsequent major complications.
