Abstract

We report two cases of infected nonfunctioning kidney due to ureteropelvic junction (UPJ) stenosis treated by laparoscopic surgery. Patient 1 : A 78-year-old woman was referred to our clinic complaining of left flank pain and high fever up. Asymptomatic UPJ stenosis with mild hydronephrosis was diagnosed 9 years ago at our clinic. Therefore we followed her up with no treatment. Computed tomography (CT) scan revealed left severe hydronephrosis. Antibiotic chemotherapy was performed without percutaneous nephrostomy. Laparoscopic nephrectomy was performed with the resected renal size of 10 cm in greatest diameter and the operative time of 262 min. The pathological diagnosis was atrophic kidney with pyelonephritis. Patient 2 : A 28-year-old man was referred to our clinic complaining of left flank pain and high fever up. CT scan revealed a left severe hydronephrosis due to UPJ stenosis. Following percutaneous nephrostomy, antibiotic chemotherapy was performed. Laparoscopic nephrectomy was performed with the resected renal size of 6 cm in greatest diameter and the operative time of 140 min. The pathological diagnosis was atrophic kidney with pyelonephritis. Laparoscopic nephrectomy for infected nonfunctioning kidney due to UPJ stenosis is feasible and safe. With dense perinephric adhesions and failure to progress, we should consider early open conversion to reduce morbidity.
