[Kidney surgery using lumbar endoscopy: initial experiences].

OBJECTIVES: To evaluate the feasibility, safety and clinical value of lumboscopy for the treatment of upper urinary tract diseases. METHODS: Six nephrectomies, one renal biopsy and one renal cystectomy were performed by retroperitoneoscopy (lumboscopy) in 7 patients. These cases represent the beginning of our experience. The operating time, incidence of intraoperative or postoperative complications and length of hospital stay were studied. RESULTS: The mean operating time was 134 min for nephrectomy, 180 min for cystectomy and 30 min for renal biopsy. No complications were observed. No conversion into laparotomy was required. The mean postoperative hospital stay was 3 days in the patients who were submitted to a single operation. CONCLUSION: Lumboscopy is a relatively easy, safe and reliable technique, and its use in urology warrants further study and development. Dissection of the retroperitoneal space with low pressure CO2 is possible and simplifies the procedure, without increasing the risks for the patient. The indications, especially for nephrectomy, are currently under evaluation.

[Urethro-vesical stenosis after radical prostatectomy].

Stricture of the urethrovesical anastomosis is an uncommon complication of radical prostatectomy, but it can affect the patient's quality of life. From January 1991 to December 1993, 50 patients underwent radical prostatectomy for clinically localised prostatic cancer (41 via a retropubic incision and 9 via a perineal incision). We retrospectively studied the influence of several factors on the incidence of anastomotic stricture: history of prostatic surgery, surgical incision, blood loss, pathological stage, presence of a contrast agent leak during follow-up urethrocystography, postoperative adjuvant treatment, oncological status at the time of the stricture. Seven patients developed clinically significant anastomotic stricture (14%). The time to onset was 1.5 to 10 months (median: 3 months). We were unable to demonstrate any pre-, intra- or postoperative or histological factors able to predict the development of anastomotic stricture. The transperineal approach appears to be associated with a lower incidence, but this finding must be confirmed in a larger series of patients. The seven patients with an anastomotic stricture were treated by endoscopic scalpel incision of the stricture, followed by insertion of a 22 F Foley catheter for 48 hours. No patient has developed a recurrent stricture with a mean follow-up of 8 months (0 to 13 months). Postoperative continence was normal in every case.

Pyloroplasty for the unusual perforated duodenal ulcer.

The performance of a large number of pyloroplasties upon patients with perforated duodenal ulcers gave us an opportunity to observe some instances of unusual perforations of the superior duodenal border from ulcers of the posterior wall. A technique of treating these very severe ulcerations without antral resection by pyloroplasty is described herein. Eighteen patients have been operated upon without mortality up to December 1978.
