Duplicated Renal Collecting System With Ectopic Ureter in Female Bladder Exstrophy: A Case Report

Bladder exstrophy is a rare major birth defect which requires specialized surgical care. Associated genitourinary tract anomalies are extremely rare in this population, yet significantly impact surgical planning and outcomes. In this case, a full-term newborn girl with a prenatal diagnosis of classic bladder exstrophy was found to have a complete duplicated left collecting system with an ectopic ureter inserted to urethral plate. The patient underwent modern staged repair of exstrophy with bilateral anterior innominate osteotomies and concomitant ureteral reimplantation-the first reported case of ureteral reimplantation at the time of initial closure in a newborn.
