Abstract :

Percutaneous nephrolithotomy (PNL) and retrograde intra-renal surgery (RIRS) are the standard treatments used in the endoscopic treatment of kidney stones. The purpose of the study was to show the radiation exposure difference between the minimally invasive techniques. This is a prospective study which included 20 patients who underwent PNL, and 45 patients who underwent RIRS in our clinic between June 2014 and October 2014. The surgeries were assessed by dividing them into three steps: Step 1: The access sheath or ureter catheter placement, Step 2: Lithotripsy and collection of fragments, and Step 3: Double J catheter or re-entry tube insertion. For the PNL and RIRS groups, mean stone sizes were 30 mm (range 16-60), and 12 mm (range 7-35); mean fluoroscopy times were 337 sec. (range 200-679), and 37 sec. (range 7-351); and total radiation exposures were 142 meq (44.7 to 221), and 4.4 meq (0.2 to 30), respectively. Fluoroscopy times and radiation exposures at each step were found to be higher in the PNL group compared to the RIRS group. When assessed for the 19 PNL patients and the 12 RIRS patients who had stone sizes �2 cm, the fluoroscopy time in Step 1, and the radiation exposure in Steps 1 and 2 were found to be higher in the PNL group than the RIRS group (p<0.001). Although there is need for more prospective randomized studies, RIRS appears to be a viable alternate for PNL.
