Abstract

Objective: The aim of this study was to present outcomes of our patients who had undergone retrograde intrarenal surgery (RIRS) with fluoroscopy-free technique and evaluate the efficacy and safety of the technique.

 

Material and methods:  Between January 2013 and June 2015 the outcomes of 93 patients who had undergone RIRS with fluoroscopy-free technique were retrospectively evaluated. Our RIRS technique  involved  preoperative assessment of ureter by semi-rigid ureteroscope, inserting guidewire through semi-rigid ureteroscope, inserting ureteral access sheath over the guidewire with the visiual guidance of semi-rigid ureteroscope, passing flexible ureteroscope through the sheath, dusting the stone with holmium laser, rechecking the ureter with semi-rigid ureteroscope and inserting double J stent through semi-rigid ureteroscope. Low-dose computerized tomography scan was performed to all patients in postoperative first month and the results were classified as stone-free (absence of any fragment), clinically insignificant residual fragments (CIRF) (≤4 mm) and residual stone.

 

Results: Study population consisted of 62 (66.6%) male and 31 (33.3%) female patients with a mean age of 47.8±14 (range 14-93) years. Mean stone size was 14.7±5 (7-32) mm. Median operative time was 72 (30-125) minutes. Stone-free rate was achieved in 65 (69.9%) patients while CIRF was achieved in 13 (13.9%) and residual stones were detected in 15 (16.1%) patients. Five patients (5.37%) had minor complications, including hematuria and fever. No major complications were observed.

 

Conclusion: Fluoroscopy-free technique is effective and safe technique in management of renal stone. Furthermore fluoroscopy-free technique can protect the surgeon from the negative effects of radiation.
