Comparison Between The Efficacy Of Transureteral Lithotripsy And Extracorporeal Shock Wave Lithotripsy In The Treatment Of Distal Ureteral Stone

Abstract

he distal ureter is the location of the great majority of ureteric stones, stones with a diameter of <5 mm have a high chance of spontaneous expulsion, active intervention is often required for larger distal stones. Ureteroscopic lithotripsy (URS) and extracorporeal shock wave lithotripsy (ESWL) are principle therapies in distal ureteral calculi treatment with satisfactory curative effect in the vast majority of cases, and both have its own advantages and disadvantages. The reported advantages of ESWL include: less invasiveness, short hospitalization, and a lower complication rate. However, ESWL is not available in many centers and often requires multiple treatment sessions. URS shares the advantages of a more rapid stone clearance but often requires anesthesia, longer hospitalization, and it is often associated with a higher incidence of complications the choice between ESWL and URS depends on multiple factors, Mainly 3 factors are important for the selection of treatment modality which is stone related factors, clinical factors and technical factors. This study was performed at Ain Shams University (Urology department) and El Doaah hospital (Urology department), From August 2016 to August 2017, a total of 70 patients having solitary radiopaque large distal ureteral sto
