title: Bladder agenesis and bilateral ectopic ureters draining into the vagina in a female infant: demonstrated by MR imaging.
abstract: Complete agenesis of the bladder and urethra is an extremely rare congenital anomaly and most of these patients are stillborn or die during infancy. We report the case of a 1-month-old female infant with bladder and urethral agenesis who presented with bilateral dilated and tortuous ectopic ureters draining into the vagina diagnosed using MR imaging. Our patient was maintained on antibiotic prophylaxis and she remained well during the 3-year follow-up. MR imaging can be used as a valuable modality for genitourinary abnormalities, particularly in cases of inconclusive ultrasound or retrograde pyelography findings.
