Abstract

PURPOSE: We evaluated the advantages of simultaneous procedure in bilateral percutaneous nephrolithotomy for the management of bilateral renal stones.
MATERIALS AND METHODS
The charts of patients with bilateral renal stones from January 1990 to April 1998 were retrospectively reviewed. We compared operative time, hospital stay, decrease in hemoglobin, and complications of simultaneous procedure with those of sequential procedure.
RESULTS
Among the 13 patients with bilateral renal stones treated percutaneously, 9 patients were underwent simultaneous procedure and 4 patients were underwent sequential procedure. Mean operative time was 190 minutes in simultaneous group and 335 minutes in sequential group (p<0.05), mean hospital stay was 10.1 and 16.8 days (p<0.05) and mean decrease in hemoglobin was 2.6 and 1.6g/dl (p>0.05), respectively. Complications included blood loss requiring transfusion in 1 case and paralytic ileus in 1 of simultaneous group, and blood loss in 2 and fever in 1 of sequential group.
CONCLUSIONS
Simultaneous bilateral percutaneous nephrolithotomy is a well-tolerated, safe, expeditious, and cost-effective approach to patients with bilateral renal stones at centers proficient in percutaneous techniques.
