Effectiveness Of Double J Stent With Extracorporeal Shockwave Lithotripsy: An Analysis Of Stone-Free Rates

Abstract

Introduction: Preservation of renal function and integrity is of profound importance and therefore renders stent-related symptoms a secondary concern. The usage of DJ stent is known for decades to support stone removal, this study aims to assess the effect of DJ stent after extracorporeal shock wave lithotripsy for stone removal and DJ stent-related complications in adult patients. Methods: This is a prospective, comparative study, Patients were selected after being diagnosed with established radiological evidence of a single radio-opaque stone ≤ 2 cm. The presence of the visible radio-opaque shadow post-procedure indicated residual stones and negative results. Primary follow-up was recommended after 2 weeks post-procedure and participants were inquired about all the anticipated complications, data was entered on SPSS version 23.0 for analysis. The chi-square test was applied to assess the significance and a p-value ≤ 0.05 was deemed significant for our results. Results: The sample size of the study was 150, sorted equally into two separated groups categorized by presence and absence of DJ stent after ESWL, stone size was almost similar to avoid any confounding factor with the mean value of 1.24 ± 0.2 in group A and 1.6 ± 0.1 in group B, with a p-value of 0.05. Hematuria was categorized within mild 6(4%) & 7(4.6%), moderate 6(4%) & 5(3.3%) while gross hematuria was reported in 1(0.6%) & 2(1.3%) in group A and B respectively. Conclusion: This study concluded that using a DJ stent with ESWL does not help in the stone passage or improve stone-free rates of stone removal after breaking the calculi with shockwave lithotripsy.
