A Prospective Randomized Comparative Study between Extracorporeal Shock Wave Lithotripsy and Rigid Ureteroscopy in Treatment of Mid-Ureteric Stones

Abstract

his study was performed at Ain Shams University (Urology department) and El Doaah hospital (Urology department), From August 2016 to August 2017, a total of 50 patients having solitary radiopaque middle ureteral stone ranges between 0.5 – 1.5 in size were divided into two groups 25 patients each enrolled in our prospective study. All patients were subjected to preoperative evaluation in the form of full history, physical examination, laboratory investigations. Patients of the first group were treated by URS with Trans-ureteral pneumatic lithotripsy (Swiss lithoclast) while patients of the second group were treated with ESWL (Dornier lithotripter S). The aim of our study was to compare efficacy, stone-free rate, cost effect, retreatment rates, associated complications (intra-operative and post-operative), operative duration and hospital stay between ESWL and semi rigid URS in mid-ureteric stones range 0.5-1.5 in size. The results of the study were: In this study the overall stone free rate was considered after three sessions of ESWL (in case of ESWL group) or one trial of ureteroscopy (in case of URS group).
