Objectives: To assess the outcome of flexible Ureterorenoscopy (F-URS) and LASER lithotripsy as a treatment modality for 2 cm-3 cm renal stone.
Patients and methods: 128 patients underwent F-URS for renal stones were enrolled. 75 Patients had stone burden <20 mm were allocated to group I while 53 patients had stone burden 20 mm-30 mm were allocated to group II. A propensity score matching was implemented to match both groups. After matching, each group included 53 patients. Thereafter, both groups were compared according to Stone Free Rate (SFR), needs for auxiliary procedure and complications.
Results: After matching, the mean operating time in Group II was higher than that in group I p=0.0176. No statistically significant difference in stone free rate between both groups 86.79% VS 75.47% p=0.693. There was a significant difference in need for a second session of RIRS between two groups (P=0.03).
Conclusion: F-URS is a feasible treatment modality for stone 20 mm-30 mm. Need for another procedure and prolonged operative time should be taken into consideration.
