Objective: Our aim is to evaluate and present the characteristics of patients underwent nephrectomy due to non-functional kidney secondary to urolithiasis in our clinic. Methods: Totally 696 patients were anlyzed retrospectively who underwent nephrectomy in our clinic between January 2000 and December 2012. Etiologies and characteristics of nephrectomy applied patients due to non-tumoral non-functional kidney related with urinary tract stones are evaluated. Diagnoses of the patients were confirmed by using urinary system ultrasonography, abdominal computed tomography, intravenous urography and renal scintigraphy. Results: Nephrectomy was performed for 280 (40.2%) patients due to tumor formation and for 416 (59.8%) patients due to non-functional kidney of totally 696 patients. 43.8% (182) of non-funtional kidney cases were resulted by upper urinary tract stones. Mean age of nephrectomy performed urolithiasis patients were 43.7±16.9 years. 53.3% (97) of patients were male and 46.7% (85) patients were female. Preoperative mean creatinine value of patients were detected 2.98±0.47 mg/dl. Renal stone localizatian was ureteropelvic junction in 81.3% (148), ureter in 14.3% (26) and renal+ureter in 4.4% (8) of the patients. 66.8% of ureteropelvic junction stones were 10-30 mm in size. Conclusion: Upper urinary tract stones are primer responsible of non-functional kidney development besides forming most of the non-tumor related nephrectomies. Routine urinary system examination should be suggested to patients with a history of urolithiasis in order to prevent later probable organ losses.
