| Popis: | Purpose: To present the results and complications of retrograde ureteroscopic lithotripsy for treatment of large ureteral stones. Methods: Nineteen patients were treated for ureteral stones ≥15 mm detected in CT or plain KUB film. Endoscopy was performed with either a semirigid or flexible ureteroscope. Stone fragmentation was performed using a 30 W Holmium laser. Results: The mean stone size was 20.7 mm (range 15–30). The mean duration of the operation was 82 min (45–140). Measures to prevent retropulsion of fragments into the kidney were not routinely applied. A subsequent RIRS during the same session was necessary in 2 cases. After a single procedure a stone free state was achieved in 15 cases (78.9%), while 4 others required a second session (ESWL or second ureterolithotripsy, 2 cases each). In only 1 patient, the stone-free state was not achieved after a 1.2 procedure per patient (overall success rate 94.7%). The mean duration of hospitalization was 1.9 days (range 1–5). Three patients experienced postoperative pyelonephritis and 2 others prolonged hematuria. Conclusion: Endoscopic lithotripsy is safe and effective in treating large ureteral stones. After a single endoscopic procedure, approximately 4 out of 5 patients are expected to become stone free. This rate increases to 95% with a second session of lithotripsy. |
