Objectives: To report a technique for ureteroscopic laser lithotripsy (URSL) and retrograde placement of a double-J (DJ) stenting through the ureteroscope working channel without the use of a fluoroscope compared to the conventional technique. Patients and Methods: Between June 2015 and December 2017, 170 patients selected for URSL for treatment of ureteral stones and DJ insertion was evaluated. Patients are divided into two groups according to the use of fluoroscopy. In Group A (100 patients), fluoroscope is used and group B (70 patients) without fluoroscopy guidance. In group B, URSL is performed first and followed by DJ insertion by the semi-rigid ureteroscope 8.5-11 Fr under vision without fluoroscopy. Results: Stone free rate in 96% versus 94.3% for groups A and B respectively. This technique was successful in all the included patients: 166 retrograde DJ stenting post URSL for ureteric calculi and 4 cases for anuria. Group A are exposed to radiation with mean 26.6 seconds in URSL procedure and 4.8 seconds for DJ stenting. Group B was exposed to zero dose. For group A, the stents size was 6 Fr for 70% of patients and 15 % for 4.7 Fr and 15% for 7 Fr stenting. In Group B, stents of 4.7 Fr and length 24-26 cm were used in all patients. Failure of DJ insertion is reported in 9% for group A and 13 (18.5%) patients for group B. Conclusions: This study report the feasibility and efficacy of the completely fluoroscopy free URSL and DJ stenting to treat ureteric stones.
