Introduction: Shock wave lithotripsy is a safe and effective therapy for nephrolithiasis, with minimal intrusive procedures. A variety of technical factors, as well as the patient's preferences, might have an influence on the procedure's outcome. The goal of this research was to identify the NCCT characteristics that would indicate if shock wave lithotripsy (SWL) is successful in treating ureteral stones. Methods: The research comprised 102 patients who got SWL for ureteral stones detected by non-contrasted computed tomography at the Department of Urology, NMCH, Sasaram, Bihar, between September 2019 and November 2022. Remaining stones larger than 4 mm were declared failures. Age, gender, BMI, stone size, location, skin-to-stone distance (SSD), the existence of a Double J stent (JJ stent), and the presence of secondary symptoms (hydronephrosis, renal enlargement, perinephric fat stranding, and tissue rim sign) were all assessed. Results: In 102 patients, stone size and density were highly associated with SWL outcomes, with a success rate of 61.8%. Secondary symptoms such as tissue rim sign, perinephric fat stranding, and hydronephrosis, as well as SSD, JJ, and SSD, were mild. According to multivariate analysis, the two independent variables impacting the result of SWL were stone size and density. Conclusions: The research found that in people with upper ureteral stones, stone size and density are major and independent predictors of outcome. SSD and impaction markers must still be evaluated, however. [ABSTRACT FROM AUTHOR] |
