Comparison of laparoscopic and open nephrectomy for adult polycystic kidney disease: operative challenges and technique.

OBJECTIVES

Autosomal dominant polycystic kidney disease an inherited systemic disorder is characterized by the development of multiple cysts in the kidneys and other organs. When nephrectomy is indicated, the laparoscopic approach is challenging due to the massive size of these kidneys. We present our technique and evaluate the surgical outcomes of laparoscopic versus open nephrectomy for patients with such condition.

MATERIALS AND

METHODS

A retrospective review was done for six laparoscopic and six open nephrectomies performed by two laparoscopic surgeons in two university hospitals between January 2004 and December 2004. Preoperative, intraoperative, and postoperative data are presented. A standard subcostal incision was used for the open cases while for the laparoscopic approach a 3-4-port transperitoneal laparoscopic approach was used to dissect the involved kidney, which is then removed intact or morcellated through pfannenstiel, midline, or expanded port site incision.

RESULTS

The laparoscopic patients had a longer operative time with one major complication compared to the open group. On the other hand laparoscopic group achieved minimal blood loss, less narcotic requirement and a shorter hospital stay. No conversion to open required in the laparoscopy group. At a median follow up of 1 year no long-term complications reported in either groups.

CONCLUSIONS

Laparoscopic nephrectomy for polycystic kidney disease is a feasible and safe alternative to open approach. In addition to low morbidity, other advantages of laparoscopic surgery also achieved in this subset of patients such as the ability to remove the dissected kidney through a small incision, reduced postoperative pain, short hospital stay, and excellent cosmesis.
