Results of treatment of 204 elderly and senile patients who underwent cystprostatectomy or anterior pelvic exenteration are analyzed. A comparative analysis of two groups of patients whose operation ended with the traditional drainage through the anterior abdominal wall (n = 100), and bilateral perineal drainage (n = 104) is presented. Bilateral perineal drainage after operations on the pelvic organs, accompanied by cystectomy and extended lymphadenectomy in conjunction with the restoration of the peritoneum lateral pelvic walls, improves postoperative recovery of intestinal peristalsis, promotes an earlier reduction in the intensity of pain and morbidity in the early postoperative period. Perineal installation of drains is a simple in design and safe procedure. We recommend bilateral perineal drainage after operations on the pelvic organs, accompanied by cystectomy and extended lymphadenectomy.
