Abstract

For ureteric stones that do not respond to medical expulsive therapy or shockwave lithotripsy, ureteroscopic lithotripsy is regarded the first-line treatment. The goal of this study was to examine a modified strategy for stone entrapment using the Dormia basket to avoid proximal stone migration during ureteroscopic pneumatic lithotripsy of ureteric stones. Material and Method: Our analysis included all cardiac patients who underwent ureteroscopic pneumatic lithotripsy for ureteric stones 15 mm in size. Study was done between July 2022 to June 2023. Study was conducted at the Department of Urology and Cardiology, St John's Medical College Hospital, Bengaluru, Karnataka, India. The study had two limbs that were conducted over two consecutive periods; the first arm included 70 patients was used, and the second arm included 80 patients. Result: Gender, age, and stone properties were comparable in both groups. Lower ureteric stones were the most common, accounting for 16.7% of all cases, whereas upper ureteric stones were discovered in 16.7% and 17.4% of cases, respectively. There was a considerable difference in operative time, with the mean operative time in Group 1 being 50 minutes against 56 minutes in Group 2. The complications were modest and comparable between groups. Although there was no difference in hospital stay between the groups, the cost analysis favored Group 2. Conclusion: We discovered that our modified-basket stone entrapment technique outperformed in preventing stone retropulsion during ureteroscopic pneumatic lithotripsy. Our basket alteration was proven to be practicable, efficient, safe, reproducible, and cost-effective in reducing proximal stone migration. This method is very useful in low-cost situations
