Abstract
Purpose: This study aimed to evaluate the efficacy and outcome of flexible ureterorenoscopy in patients with hematuria, upper urinary tract calculi and tumor.
Materials and Methods: A retrospective chart review for the application of flexible ureteroscopy was performed. From October 1998 to January 2016, 70 patients were treated with flexible ureterorenoscopy. Diagnostic flexible ureteroscopy for hematuria was arranged in 15(21.4%) patients, flexible ureterorenoscopic lithotripsy for upper ureteral and renal calculi in 54(77.1%) and flexible ureterorenoscopic renal pelvic tumor biopsy in 1(1.4%). The Patients' age, gender, body mass index (BMI), operative time, stone-free rates, perioperative event, and complication rate were recorded and analyzed.
Results: In this study, the mean age of the 70 patients was 52.3±16.1 years(range 26-82 years). The operative time ranged from 20 to 150 minutes (mean: 55minutes). In 54 patients with upper ureteral and renal calculi, the mean stone size was 8.5±4.1 mm (range 3-32 mm), the stone-free-rate was 74% after procedure. The mean hospital stay was 3.1±1.2 days. The overall complication rate was 2.9%,
Conclusion: Flexible ureterorenoscopy is a safe and effective option for the confirmation of upper urinary tract tumor, especially for those who failed to perform contrast medium enhanced image study. It is also a good choice to treat the difficult stone located in upper ureter and kidney.
