Retroperitoneal surgery of the kidney, ureter and adrenal gland.

Seventy-one retroperitoneal endoscopic procedures on the kidney, ureter and adrenal gland were performed in 69 patients, using the balloon technique of retroperitoneoscopy. There were 9 failures in this series, all of which were converted into an open procedure. The balloon satisfactorily dissected the kidney and the ureter in 59 patients (85%). There were no major complications and the minor complication rate was 20%. Forty-nine patients were discharged the next day, while 20 were kept in hospital for 2 to 5 days. The balloon technique of retroperitoneoscopy is safe, simple and reliable for exposing the kidney, ureter and the adrenal gland.

Retroperitoneal laparoscopic varicocelectomy.

Retroperitoneal laparoscopic varicocelectomy was performed in 27 of 29 patients with clinical varicoceles. Postoperative pain was minimal and all patients were discharged from the hospital within 24 hours. The technique is relatively safe and easy to learn, although identification of the internal spermatic vein may sometimes be difficult. It could become a viable alternative to the transperitoneal laparoscopic procedure in patients with pelvic adhesions or those having recurrent varicoceles due to high collaterals.

Laparoscopic renal biopsy via retroperitoneal approach.

Renal biopsy was performed in 17 patients using the balloon technique of endoscopy of the retroperitoneum. There was good exposure of the kidney and a sufficient amount of renal tissue was obtained in all patients with minimum postoperative morbidity. The preliminary results show that this method could become a safe and reliable alternative to open surgical biopsy.

Retroperitoneal laparoscopic pyelolithotomy.

Retroperitoneal laparoscopic pyelolithotomy was successful in 5 of 8 patients using the recently described balloon technique of retroperitoneal laparoscopy. All patients were considered for this new minimally invasive procedure only on economic grounds. However, with improved technique and instrumentation, the retroperitoneal laparoscopic approach could become a practical alternative for the management of patients with medium sized pelvic stones not amenable to extracorporeal shock wave lithotripsy nor ideally suitable for percutaneous nephrolithotomy, or when both of these facilities are not available.

Laparoscopic condom dissection: new technique of retroperitoneoscopy.

The laparoscopic condom dissection is an advancement on the recently described balloon dissection technique of retroperitoneoscopy. It allows a simultaneous balloon dissection and retroperitoneal laparoscopic dissection using a telescope placed inside a condom balloon. In spite of a mild masking effect by the balloon, the clarity of vision was satisfactory, and adequate dissection could be carried out in all five patients in whom the condom was placed deep to the fascia transversalis or Gerota's fascia.

Retroperitoneoscopy: the balloon technique.

Retroperitoneoscopy was performed in 101 patients using the author's recently described balloon technique. Various urological procedures, were undertaken including renoscopy and renal biopsy, para-aortic lymph node biopsy, varicocelectomy, ureterolithotomy, pyelolithotomy, pyeloplasty, nephrolithotomy, nephrectomy, decortication of renal cyst, adrenalectomy, pelvic lymphadenectomy and ligation of deep penile veins.

Retroperitoneal laparoscopic ureterolithotomy.

Retroperitoneal laparoscopic ureterolithotomy was successfully performed in five patients with calculi impacted in the upper and middle ureter, using the recently described method of retroperitoneoscopy. All of the patients were discharged the following day but could have been treated as day cases.

Retroperitoneal endoscopic ureterolithotomy: our experience in 12 patients.

Retroperitoneal endoscopic ureterolithotomy was successful in 9 of 12 patients who had calculi impacted in the upper and mid ureter with gross hydronephrosis and recurrent infection. This procedure was made possible by the technique of balloon retroperitoneoscopy recently described by the author.

Laparoscopic operative retroperitoneoscopy: use of a new device.

Attempts at retroperitoneoscopy have mostly failed in the past due to the inability to create an effective pneumoretroperitoneum because of the dense areolar tissue binding the fat in the retroperitoneum, which could not be broken down merely by pneumo-insufflation. The newly devised balloon breaks the septae, lifts the peritoneum atraumatically and creates a workable space in the retroperitoneum. The view of the retroperitoneal structures provided is satisfactory. With this balloon dissector we have performed laparoscopic ureterolithotomy, renoscopy and renal biopsy, para-aortic lymph node biopsy and ligation of the internal spermatic vein.

Endourethral urethroplasty--use of a new catheter.

Endourethral split skin grafting following visual internal urethrotomy was done successfully in 7 selected patients with stricture of the bulbomembranous urethra. Open substitution or anastomotic urethroplasty might otherwise have been necessary in these patients. The technique involves the use of a specially designed double balloon catheter, in which the second balloon, when distended, keeps the split skin graft in close opposition with the urethral raw area. This function ensures a near 100 per cent graft take, keeps the strictured area wide open and allows early ambulation of the patient, since no perineal compression dressing is required.

Single implants in the treatment of erectile impotence.

A total of 12 patients with erectile impotence underwent implantation of a Finney flexirod penile prosthesis in 1 corpus cavernosum only. This procedure has a special advantage in developing countries since the cost of the operation in reduced by approximately 50 per cent. The penis is less rigid and longer, and in case of failure the other corpus cavernosum is readily available. This procedure is the method of choice in cases of psychogenic impotence since there is a considerable amount of super erection present in all of the cases.
