Objective. Comparison of outcomes between RIRS with vacuum-assisted ureteral access sheath (V-UAS) and MPCNL in the treatment of renal stone. Materials and Methods. 28 patients with 2-4 cm renal stone were treated using RIRS with 14/16 F V-UAS. The outcomes were compared to those who underwent MPCNL with 16 F Amplatz sheath using a matched-pair analysis in a 1 : 2 scenario. Matching criteria included stone size, location and laterality, gender, age, BMI, and degree of hydronephrosis. Patients’ demographics, perioperative and postoperative characteristics, complications, stone-free rate (SFR), and auxiliary procedures were compared. Results. Mean operative times for the RIRS and MPCNL groups were 72.4±21.3 minutes and 67.4±25 minutes (P=0.042). Postoperative pain was significantly less in the RIRS group. The initial SFR was 50% for the RIRS group and 73.2% for the MPCNL group (P=0.035). The final SFR at postoperative three months improved to 89.3% for the RIRS group and 92.9% for the MPCNL group (P=0.681). The auxiliary procedure rates were higher in the RIRS group (42.9% vs. 25%, P=0.095). The overall complication rate in the RIRS group was lower, but the significant difference was not found. Conclusion. In the treatment of 2-4 cm renal stone, using V-UAS in RIRS can improve surgical efficiency with lower postoperative early pain scores. Comparing with MPCNL, its initial SFR was more depressed, and there is still a trend towards requiring more auxiliary procedures to achieve comparable final SFR.

Aim: To analyze the ureteral injury and incidence of ureteral stricture in a series of patients who underwent retrograde intrarenal surgery with using smallest ureteral access sheath. Materials and Methods: Between September 2016 and March 2019, 154 consecutive retrograde intrarenal surgery procedures with adjunctive use of an ureteral access sheath for kidney stone were prospectively included the study. A 9.5/11.5-F ureteral access sheath was used during procedures. The patients were evaluated in terms of intraoperative postoperative and late complications. Ureteral injuries after retrograde intrarenal surgery were assessed visually with flexible and semirigid ureterorenoscope. All patients were evaluated by computed tomographic urography in the first year after treatment for detection of ureteral stricture. Results: The mean age of the patients was 47±15 (12-81) years. Of the patients, 86 were male and 68 were female. Mean stone size was 17.1±8 (7-40) mm and mean operative time was 56±23 (30-120) minutes. Overall 79.9% of patients had evidence of injury to the ureter wall. Non-significant lesion (grade 0) was seen in 39.0% of patients. Grade 1 lesions were assigned in 40.9% of patients. There were no grade 2 and higher lesions detected. A total of 5 patients (3.2%) had minor complications. Urinary sepsis developed as a major complication in 3 patients (1.9%). No ureteral stricture was detected in the patients at first year control. Conclusions: The results of our series indicate that the 9.5/11.5-F ureteral access sheath is safe for routine use to facilitate flexible ureteroscopy and there was no long-term adverse effect.
