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

摘要

Objectives: To measure the incidence of stone Retropulsion and its complicationin ureteroscopic pneumatic lithotripsy for lower ureteric stones by using stone cone. StudyDesign: Observational cross sectional study. Setting: Department of Urology, Teaching DHQHospital Gujranwala / Gujranwala Medical College, Gujranwala. Period: January 2017 toDecember 2018. Material & Methods: Consecutive simple random sampling technique wasused. Total 120 patients were treated with URS pneumatic lithotripsy for single ureteric stonewere 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 wasanalyzed using SPSS 22.0, chi square test was used to check stratification of data, p value lessthan 0.05 was taken significant. Results: The stone was in lower ureter in all patients who wereincluded 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) achievedin patients in which stone cone was used. Conclusion: Use of stone cone gives high successrate in preventing stone Retropulsion by using pneumatic lithotripsy.
