Aim: The results of retrograde intrarenal surgery in 280 cases according to stone size were retrospectively evaluated. Material and Methods: Between September 2014 and February 2016, flexible ureterorenoscopy was performed in 280 cases with upper urinary tract stone disease. Stone or stones were fragmented until smaller than 3 mm under vision. Larger than 3 mm stones were accepted as the clinical significance residual stones. Results: Stone treatment with flexible ureterorenoscopy was performed in 197 male and 83 female patients. Median age was 45.8 years and median stone size was 16.9 mm 7- 40mm . Median operation time was 47.6 min 30-90 min . Double J stent was placed in 212 patient 75.7% after the operation while 68 patients 24.2% who has a very short operation time, without residual stone and ureteral damage was not placed. Ureteral access sheath was inserted at first procedure in 256 patient, 17 patient was inserted after the 3 week double J stent period. 229 81.7% patient stones were fragmented at first procedure but 51 18.2% patient had seconder procedure for residual stones. Severe bleeding did not occur during flexible ureterorenoscopy. In one patient developed ureteral injury inserting double J stent was unsuccesfully and was converted to open surgery. Conclusion: Flexible ureterorenoscopy is effective and reliable surgical procedure with high stone free rates and low morbidity in upper urinary system stone treatment.
