A 30-year-old man presented with upper mid ureteral calculi and gross hydroureteronephrosis. The 4 large and 2 small calculi were removed successfully using Gaur's technique of retroperitoneal laparoscopy.
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 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 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.
Pre-transplant nephrectomy was done in a 25-year-old man for calculous pyelonephritis using a retroperitoneal laparoscopic approach with a newly devised ligature applicator-dissector- kidney retractor.
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.

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 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.
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.
