The Stone Clearance rate of Intracorporeal Pneumatic Lithotripsy for Mid Ureteric Stone of Size 1-2cm

Original Article

Abstract

Background : Urinary stones are a common urological issue with high recurrence and potential complications. Treatment options include Shock wave Lithotripsy, Ureterorenoscopy, and surgery, chosen based on stone size, location, and resources. The EAU recommends Shock wave Lithotripsy or Ureteroscopic Laser Lithotripsy for middle ureteral stones due to their minimally invasive nature. Advances in ureteroscopes and laser lithotripsy have improved outcomes for stones >1 cm.

Objectives:

To determine the frequency of clearance of middle ureteric stone of size more than 1cm with ureterorenoscopic lithotripsy in patients presenting to tertiary care hospital.

Materials and Method:

This 6-month descriptive study at a tertiary care hospital in Peshawar included 183 patients aged 18–60 years with middle ureteric stones sized 1–2 cm. Patients were selected through non-probability consecutive sampling. Stone clearance was defined as the absence of ureteric stones on non-contrast CT KUB after 2 weeks.

Results:

The mean age of the patients was 39.89 ± 12.38 years. In our study, 103 patients (56.3%) were male and 80 patients (43.7%) were female. Stone clearance was confirmed by CT KUB in 147 patients (80.3%).

Conclusions:

In our study, ureterorenoscopic lithotripsy achieved an 80.3% clearance rate for >1 cm mid-ureteric stones, with higher success in older patients and right-sided stones.
