Staged nephrectomy versus bilateral laparoscopic nephrectomy in patients with autosomal dominant polycystic kidney disease.
OBJECTIVE
In patients with autosomal dominant polycystic kidney disease we compared the outcome of bilateral laparoscopic nephrectomy at a single operation vs staged nephrectomy, including 1 during transplantation and the other via laparoscopic unilateral nephrectomy.


METHODS
We reviewed the records of patients with autosomal dominant polycystic kidney disease requiring renal transplantation and native bilateral nephrectomy. We compared transplantation with ipsilateral nephrectomy to transplantation alone and then compared unilateral to bilateral laparoscopic native nephrectomy. Indications included pain, infection, bleeding and compressive symptoms.


RESULTS
We followed 42 patients, including 16 with transplantation and nephrectomy, 22 with transplantation alone and 4 awaiting transplantation. In those with transplantation vs transplantation with nephrectomy there were no differences in median age (48.3 vs 53.3 years, p = 0.178) or greatest kidney length (19.5 vs 20.9 cm, p = 0.262). Operative time (208 vs 236 minutes, p = 0.104), estimated blood loss (200 vs 250 ml, p = 0.625), hospital discharge creatinine (1.60 vs 1.50 mg/dl, p = 0.491) and complications were similar. We separately compared 24 bilateral and 18 unilateral laparoscopic native nephrectomies, and noted similarities in median age (52.0 vs 56.3 years, p = 0.281) and kidney length (19.5 vs 19.8 cm, p = 0.752). Bilateral nephrectomy showed greater estimated blood loss (125 vs 50 ml, p = 0.001) and operative time (302.8 vs 170.2 minutes, p <0.001). There were 4 open conversions, 9 perioperative complications at bilateral surgery and 1 complication after unilateral surgery. Median followup in the unilateral and bilateral groups was 13.3 vs 35.9 months (p = 0.015).


CONCLUSIONS
Renal transplantation and ipsilateral native nephrectomy carry no significant additional morbidity compared to that of renal transplantation alone. Staged unilateral laparoscopic nephrectomy was superior to the bilateral procedure in perioperative outcome.
