Comparison Between Retrograde and Antegrade Ureteroscopic Laser Lithotripsy for the Management of Medium-Sized Proximal Ureteral Stones: A Randomized Prospective Study.

Objectives: This study aimed to present the outcomes of retrograde and antegrade ureteroscopic laser lithotripsy in the treatment of proximal ureteral stones ranging in size from 10 to 20 millimeters in diameter.

Patients And Methods: From March 2023 to December 2023, 70 patients were included in this prospective randomized double-arm interventional study. Patients were divided into two groups: Group 1 (35 patients) had semi-rigid retrograde ureteroscopic laser lithotripsy, and Group 2 (35 patients) had semi-rigid antegrade ureteroscopic laser lithotripsy.

Endoscopic management of postoperative bile duct injuries: a single center experience.

Background/aim: Biliary endoscopic procedures may be less invasive than surgery for management of postoperative bile duct injuries (POBDI). This retrospective work presents the experience of a single referral center during a period of 14 years in endoscopic management of POBDI.

Materials And Methods: Between 1994 (March) and 2008 (May), ERCP had been performed on 277 patients suspected to have POBDI.

Bile reflux measurement and its contribution to the severity of reflux esophagitis.

Background/aims: Gastroesophageal reflux disease (GERD) may occur with acid, bile or in a mixed form. Endoscopic injury and mucosal metaplasia are a known sequelae to pathological GERD. The aim of the study was to determine the contribution of acid and duodenogastroesophageal reflux to endoscopic severity in patients with GERD and Barrett's esophagus (BE).
