PREDICTIVE FACTORS AFFECTING THE SUCCESS OF MEDICAL EXPULSIVE THERAPY IN PATIENTS WITH DISTAL URETERAL STONE
Journal Title: Kocatepe Medical Journal - Year 2024, Vol 25, Issue 4
Abstract
OBJECTIVE: In this study, we aimed to investigate the factors affecting spontaneous stone passing in patients who received medical expulsive therapy due to distal ureteral stones. MATERIAL AND METHODS: From September 2022 to October 2023, a total of 148 patients with distal ureteral stones sized 4-10 mm were included. Patients received silodosin 4 mg as medical expulsive therapy and were followed up for a maximum of four weeks. The patient- and stone-related variables affecting spontaneous stone passage were evaluated. RESULTS: The mean age of the participants was 42.92±12.78 years. The stone expulsion rate was 64.2%. The rate of spontaneous stone passage was significantly higher in patients with lower stone size, stone burden, ureteral wall thickness, distance of the stone to the ureterovesical junction, neutrophil-lymphocyte ratio and hydronephrosis grade. (all, p<0.05). The distance of the stone to the ureterovesical junction, ureteral wall thickness, and neutrophil-to-lymphocyte ratio were independent predictors of spontaneous passage (p:0.036, p:0.001, p:0.001, respectively). CONCLUSIONS: The distance of stone to the ureterovesical junction, ureteral wall thickness, and neutrophil-to-lymphocyte ratio can be useful parameters to estimate spontaneous stone expulsion. These factors play important roles in decision-making for the management of distal ureteral stones.
