Postoperative rhabdomyolysis is a rare but potentially fatal surgical complication. We experienced a case of rhabdomyolysis after laparoscopic radical nephrectomy (LRN). Right renal carcinoma was diagnosed in a 31-year-old woman with a body mass index of 28.5 kg/m2. She underwent right retroperitoneal LRN in the lateral decubitus position. The operating time was approximately 5 hours. Immediately after surgery, she reported pain in the left buttock, and reddish discoloration of the urine was observed. On the basis of these symptoms, an elevated serum creatine kinase level, and computed tomography findings, we diagnosed rhabdomyolysis of the left gluteal muscle secondary to its intraoperative compression caused by prolonged placement in a fixed position. She was treated with hydration therapy and discharged 6 days postoperatively. Prolonged surgery, obesity, and placement in the lateral decubitus position are risk factors for postoperative rhabdomyolysis. Surgeons should attempt to reduce operating time for LRN when obese patients are placed in the lateral decubitus position.
