Benefits of laparoscopic prostate-sparing radical cystectomy.

Purpose: Prostate-sparing radical cystectomy has been described in the literature and has proven to be a promising procedure owing to the continence and erectile function results without necessarily compromising the oncologic outcome in selected patients. Technique points: A transperitoneal approach is used. Lymph node dissection is performed with frozen section, and then the ureters are ligated and biopsled. The seminal vesicles are dissected, followed by complete mobilization of the bladder. Incision of the bladder neck is performed, followed by simple prostatectomy. Finally, bowel reconstruction is carried out via a small infra-umbilical incision that also permits the extraction of the surgical specimen and the anastomosis of neobladder to the prostate capsule. A total of 25 patients have undergone this procedure, with average surgical times of 285 min and blood loss of 640 ml. The complications encountered included: one bowel incarceration, one urinary leak, one lymphocele and one port hernia. At median 9 months follow-up, no patient presented with daytime incontinence, although seven complained of nocturia. A total of 20 patients maintained their preoperative sexual potency, and four reported a postoperative decrease in their erectile function. Conclusions: Laparoscopic prostate-sparing radical cystectomy appears to be oncologically safe, reproducible and has promising functional benefits. The authors believe this procedure presents a good option in very select patients.
