Özet

Objective: To investigate potential predictive factors for multiple sessions of retrograde intrarenal surgery (RIRS) to achieve stone-free status in patients with kidney stones. Study Design: A descriptive study. Place and Duration of the Study: Department of Urology, Faculty of Medicine, Yozgat Bozok University, Turkiye, from January 2015 to May 2021. Methodology: Patients who underwent RIRS for renal stones were evaluated. Patients who were stone-free following a single intervention were labelled as Group I. Patients who required further sessions of RIRS to achieve stone-free status were labelled as Group II. The predictive factors for multiple-session RIRS to achieve stone-free status were investigated. Results: A total of 487 patients were enrolled in the study. Stone located in the lower calyx, presence of hydronephrosis, and stone volume were identified as predictive factors for requiring multiple RIRS sessions in the logistic regression analysis (p = 0.042, p = 0.018, and p = 0.040, respectively). Patient characteristics such as gender and age, as well as stone characteristics including stone density, number, size, laterality, and operation time, were not predictive of the need for multiple intervention sessions. Conclusion: Patients without stones in the lower calyx, without hydronephrosis, and with a low stone burden are more likely to achieve stone-free status after a single RIRS session. Otherwise, multiple sessions may be required to achieve stone-free status.
