ABSTRACT

Introduction Significant advances and growing experience in urologic endoscopic procedures, together with progress in balloon catheter technology (Acucise™), have generated clinical data in reported series in which percutaneous (antegrade) and transurethral (retrograde) endo-ureteropyelotomy have been utilized for the management of ureteropelvic junction (UPJ) and ureteral obstruction.1-8 Although the efficacy, reproducibility, and overall decreased morbidity of endourological procedures have been clearly demonstrated, several issues are still debated, one of which is the optimal type of stenting after endo-ureteropyelotomy.
