Laparoscopic bilateral synchronous nephrectomy for autosomal dominant polycystic kidney disease: the initial experience.

PURPOSE

We report our experience with laparoscopic bilateral synchronous nephrectomy for giant symptomatic autosomal dominant polycystic kidney disease (ADPKD) and compare outcome data with open bilateral nephrectomy.

MATERIALS AND METHODS

Since March 1998, 10 patients underwent bilateral synchronous laparoscopic nephrectomy for giant symptomatic ADPKD. A 3 port retroperitoneal laparoscopic approach was used to secure the renal hilum and mobilize the kidney. Intact specimen extraction was performed through a midline infraumbilical extraperitoneal incision. The patient was then repositioned for the contralateral retroperitoneoscopic nephrectomy, with the second specimen also delivered through the same infraumbilical incision. Data were retrospectively compared with 10 patients who had undergone bilateral synchronous open nephrectomy for ADPKD between 1981 and 1992.

RESULTS

Patients in the laparoscopic and open groups were comparable in regard to age (53 versus 47 years, p = 0.54) and Anesthesiologist Society of America class (3 versus 3, p = 0.84) but patients in the laparoscopic group were significantly more obese (body mass index 35.9 versus 23.8, p = 0.02). For comparable total specimen weights (3 versus 3 kg, p = 0.69) surgical time was longer in the laparoscopic group (4.4 versus 3.8 hours, p = 0.007). However, the laparoscopic group was superior in regard to blood loss (150 versus 325 cc, p = 0.05), postoperative requirement of nasogastric tube (10% versus 100%, p = 0.0001), narcotic analgesics (34.2 versus 120.4 mg. morphine sulfate equivalent, p = 0.03) and hospital stay (1.5 versus 9 days, p = 0.004). Complications occurred in 5 patients (50%) in the laparoscopic group and 4 (40%) in the open group (p = 0.66). No laparoscopic case was converted to open surgery.

CONCLUSIONS

Synchronous bilateral retroperitoneal laparoscopic nephrectomy for giant symptomatic adult polycystic kidney disease is feasible, safe and efficacious, and can be performed either before or after renal transplantation. Compared to open surgery, the laparoscopic approach results in significantly shorter hospital stay, decreased morbidity and quicker recovery. Laparoscopy is currently our technique of choice in this setting.
