Effect of Methylene Blue Bladder Instillation on Urinary Tract Injuries During Cesarean Hysterectomy for Placenta Accreta Spectrum

This prospective cohort study aims to evaluate whether preoperative bladder filling with methylene blue dye can reduce the incidence of urinary tract injuries during cesarean hysterectomy in patients diagnosed with placenta accreta spectrum. A total of 60 patients will be randomly assigned to either an intervention group receiving methylene blue bladder instillation or a control group receiving standard surgical care. The primary outcome is the rate of intraoperative urinary tract injuries. Secondary outcomes include total operative time, , and pre and post operative hemoglobin level , number of units of packed RBCs transfused, number of units of fresh frozen plasma transfused, number of participants admitted to ICU postoperatively,number of participants with postoperative complications, duration of hospital stay of participants.

INTRAOPERATIVE BLADDER INJURY ASSESSMENT IN TURBT USING BICEP

Transurethral resection of bladder tumor (TURBT) is the cornerstone procedure in the diagnosis and treatment of bladder cancer but is associated with a spectrum of intraoperative bladder injuries ranging from minor mucosal tears to major perforations. Currently, there is no standardized intraoperative classification system specifically designed to grade and report these injuries during TURBT. This study aims to apply the Bladder Injury Classification System for Endoscopic Procedures (BICEP) to TURBT in order to systematically classify intraoperative bladder injuries, evaluate their management, and explore their association with perioperative and early postoperative outcomes.
