Objective: To evaluate outcomes of the cases who had undergone retrograde intrarenal surgery (RIRS) in our clinics. Methods: Outcomes of 100 cases who had undergone RIRS because of renal stones between February 2012, and May 2013 were retrospectively evaluated. Results: Study population consisted of 35 female and 65 male patients with a mean age of 36.81(1-76) years. RIRS was performed with the indication of rest double J (D-J) stent (n=1), and renal stone (n=99). Mean stone size was 15.26 (5-27) mm. Preoperatively, 61 cases (61%) had preexisting D-J stents, while 39 (39%) cases were stentless. Access sheaths were used in 86 (86%) cases, while in 14 (14%) cases the procedure was applied without using an access sheath. Mean operative, and fluoroscopy times were 52.72 (10-120) minus, and 57.32 (10-180) seconds, respectively. Postoperatively D-J stents were implanted in 88 (88%) cases, and 12 (12%) cases were stent-free. Mean hospital time was 1.3 (1-7) days. After one month postoperatively, stone-free rate was achieved in 87 (87%) patients. Clinically insignificant residual stone fragments (CIRF) 6 (6%), and residual stones 7 (7%) were also detected. The latter group consisted of cases with horseshoe kidney (n=1), pelvic kidney (n=1), and kyphoscoliosis (n=1). Also in two case procedure was terminated prematurely, because of blurring of the vision secondary to bleeding. Apart from these patients, any preoperative complication did not develop. During follow-up period, urinary tract infection developed in 3 patients with resultant renal parenchymal damage in one patient. In one patient, D-J stent migrated into ureter. Conclusion: Retrograde intrarenal surgery is an effective and safe technique in the management of renal stones.
