[Transumbilical laparoscopic simple nephrectomy using a flexible cystoscope and standard laparoscopic instruments].

OBJECTIVES

We present our initial experience with transumbilical surgery in a simple nephrectomy performed with a flexible cystoscope and standard laparoscopic instruments.

METHODS

A 15 year-old child, with severe left renal parenchyma atrophy, secondary to recurrent urinary tract infection (UTI) complicated with left pyelonephritis. Decision for simple nephrectomy was taken and we planned to perform a single port laparoscopic nephrectomy. In the lumbotomy position, two 5mm ports were insertend through a 3 cm umbilical incision. One trocar permitted the progression of the flexible cystoscope (Olympus) and the other the entrance of the PKS Plasma Trissector. The latter was then changed for a 10mm port to allow the entrance of the Weck clips. A Maryland grasper for countertraction was placed without port in the lef-upper quadrant and progressed directly into de peritoneal cavity under direct vision.

RESULTS

The standard laparoscopic steps were duplicated uneventfully. Mean operative time was 90 minutes and mean blood loss was 200 mL. Hospital stay was 18 hours. No transfusion was needed.

CONCLUSION

Single port urologic surgery will expand in the future. There is lack of commercial availability of the ideal hardware needed for the procedures. Versatility of urologic instruments allow for its use in different settings.
