AI Article Synopsis

  • The study compared the effectiveness of ureteroscopy and extracorporeal shock wave lithotripsy (ESWL) for treating distal ureteral stones in 104 patients requiring surgery.
  • Despite a longer procedure time for ureteroscopy, patients had shorter hospital stays and higher stone-free rates after treatment, with 74.3% for ESWL and 92.3% for ureteroscopy at 30 days.
  • The findings suggest ureteroscopy is the preferred treatment due to its higher success rate, while complication rates for both methods are comparable.

Article Abstract

Purpose: To compare the efficacy of ureteroscopy and extracorporeal shock wave lithotripsy (ESWL) in treating distal ureteral calculi and evaluate the best treatment alternative for this disease.

Material And Methods: A total of 104 patients with distal ureteral calculi requiring surgical intervention were enrolled and observed in a prospective follow-up. For ESWL, a Modulix SLX Storz lithotriptor was used and for ureteroscopy, a Storz 33 cm semi-rigid ureteroscope with a diameter of 7,5 to 9,5 french and a 6-degree optic. Out of the patient total, 54 patients underwent ESWL and 50 underwent ureteroscopy. 62 patients were men and 42 women; mean age in the ESWL group was 49.72, and in the ureteroscopy group, 52,16. Mean calculus size for ESWL was 8.29 mm and 8,96 mm for ureteroscopy. A P< .05 was considered statistically significant.

Results: Mean procedure time for ESWL was 55 minutes in men and 45 minutes in women. For ureteroscopy, procedure time was 80 minutes for men and 55 minutes for women. For ESWL, the mean hospital stay was 4.8 hours (same-day discharge for all patients). Mean hospital stay for ureteroscopy patients was 22 hours. 7% of ESWL patients experienced complications compared with 7.9% of those undergoing ureteroscopy. At the 30-day follow up, 74.3% of ESWL patients were stone free, while 92,3% of the ureteroscopy patients were stone free (P< .05).

Conclusions: Based on the results of this study, ureteroscopy is a better method for treating distal ureteral calculi because of its stone free rates and because the difference in complication rates was not significant.
