Incidence of Stone Retropulsion in Ureteroscopic Pneumatic Lithotripsy for lower ureteric stones by using stone cone.

Abstract

Objectives: To measure the incidence of stone Retropulsion and its complication in ureteroscopic pneumatic lithotripsy for lower ureteric stones by using stone cone. Study Design: Observational cross sectional study. Setting: Gujranwala Medical College, Gujranwala. Period: January 2017 to December 2018. Material & Methods: Consecutive simple random sampling technique was used. Total 120 patients were treated with URS pneumatic lithotripsy for single ureteric stone were enrolled in study. The diagnosis was established by plain spiral CT scan in all patients. The incidence of stone Retropulsion and complications of procedure were noted. Data was analyzed using SPSS 22.0, chi square test was used to check stratification of data, p value less than 0.05 was taken significant. Results: The stone was in lower ureter in all patients who were included in study regardless of side. The mean age of patients was 46±2.6 years and 65% (78) patients were male while 35% (42) patients were females. Success rate of 97.5% (116) achieved in patients in which stone cone was used. Conclusion: Use of stone cone gives high success rate in preventing stone Retropulsion by using pneumatic lithotripsy.
