Measure Twice and Cut Once: Comparing Endoscopy and 3D Cloacagram for the Common Channel and Urethral Measurements in Patients with Cloacal Malformations

Multi-center study comparing endoscopy versus 3D cloacagram for measuring common channel and urethral lengths in 72 cloacal malformation patients found significant discrepancies between modalities, with measurements differing enough to alter surgical approach selection in 21% of cases. Findings support routine use of 3D cloacagram for preoperative planning to prevent mischaracterization and ensure appropriate choice between total urogenital mobilization and urogenital separation.
