Objectives: To investigate the situations in which ureteral double-J stent should be used after retrograde intrarenal surgery (RIRS). Patients and Methods: Patients with no ureteral double-J stent after RIRS constituted Group 1, and those with double- J stent after RIRS constituted Group 2. Patients’ age and gender, renal stone characteristics (location and dimension), stone-free status, VAS score 8 hours after surgery, post-procedural renal colic attacks, length of hospitalization, requirement for re-hospitalization, time to rehospitalization and secondary procedure requirements were analyzed. Results: RIRS was performed on 162 renal units. Double-J stent was used in 121 (74.6%) of these after RIRS, but not in the other 41 (25.4%). At radiological monitoring at the first month postoperatively after RIRS, complete stone-free status was determined in 122 (75.3%) renal units, while residual stone was present in 40 (24.6%). No significant differences were observed between the groups in terms of duration of fluoroscopy (p = 0.142), operation (p = 0.108) or hospitalization times (p = 0.798). VAS values determined routinely on the evening of surgery were significantly higher in Group 1 than in Group 2 (p = 0.025). Twenty-eight (17.2%) presentations were made to the emergency clinic due to renal colic within 1 month after surgery. Double-J catheter was present in 24 (85.7%) of these patients. Conclusions: Routine double-J stent insertion after RIRS is not essential since it increases costs, morbidity and operation time.
