Background and Purpose: Shock wave Lithotripsy (SWL) has a variable but low success rate for large or non-opaque ureteral stones. Ureteroscopic stone manipulation may be the best option for all stone size, consistency and position of ureteral stones. This report examines the feasibility and effectiveness of pneumatic ureteroscopic lithotripsy for all ureteral stones.
Patients and Methods: 612 patients with impacted ureteral stones were treated with URSL using 6/7.5 F Semirigid tapering ureterorenoscope and pneumatic lithotriptor under regional or general anesthesia. Double- J Ureteral stent were placed in all patients owing to the large stone burden, edema of the intraluminal mucosa and accompanying ureteric injury. Success was defined as stone free status on parameters and outcomes were analyzed.
Result: The accessibility rate of the stone was 99.3% (608 of 612) and the stone free rate for the first achived after one setting was 78% (480 of 612), after the second or the third URSL with adjuvant treatment, the total stone free rate reached 100%. No patient needed open surgery and there were no major intra-operative complications.
Conclusion: Although 22% of patients needed the second or the third URSL with adjuvant treatment pneumatic ureteroscopic lithotripsy can be considered the best choice for all ureteral stones.
