Materials and Methods: A patient was a 62-year-old woman who had been using CAPD for 4 months because of end-stage renal disease (ESRD) secondary to diabetic nephropathy. She was referred to the urology clinic, due to suffering from the left pyonephrosis and non-functioning kidney with a proximal ureteric stone. Then she underwent percutaneous nephrostomy to drain the pus. After this resolved, she underwent LESS nephrectomy. Medical records were reviewed, and laboratory values and outcomes were analyzed. Results: The procedure was successfully completed without conversion to conventional laparoscopic or open surgery. Operative time was 160 minutes. Moreover, the specimen can be easily and rapidly extracted through the TriPort without the use of an additional entrapment bag. Estimated blood loss was 200 mL and pain scale was 0-1, with no morphine requirements. On the same day of the operative procedure, a double-lumen hemodialysis (HD) catheter was introduced for postoperative HD. The patient underwent hemodialysis treatment via a subclavian catheter after the operation and she was discharged home on the sixth postoperative day with a functioning CAPD catheter, with no further problems. After 2 weeks, the patient switched from HD to CAPD without complications. Pathological analysis revealed chronic pyelonephritis. Postoperative hematocrit, blood urea nitrogen, and creatinine were 39.3%, 22 mg/dL, 2.3 mg/dL respectively. The scars receded into the umbilicus and were hardly visible. Conclusion: LESS nephrectomy is a feasible technique with advantages of less pain, shortened convalescence, improved cosmesis, and absence of wound complications.Mahidol UniversityMedicineNoteSCOPUS10.1590/S1677-55382010000600032
