Ectopic Ureter: Spectrum of Magnetic Resonance Imaging Findings.

Objective: This study aims to describe the MRI findings of six patients with ectopic ureters in a tertiary care institute.

Methods: A retrospective analysis was conducted on six patients presenting to the Department of Radiodiagnosis at Sawai Man Singh (SMS) Hospital, Jaipur, India, with ectopic ureters. Data were collected from the 3 Tesla (3T) Philips MRI scanner (Koninklijke Philips N.V., Amsterdam, Netherlands) from 2021 to 2023.

Results: The mean age was 21.6 years, with an equal male-to-female ratio (1:1). Most patients presented with urinary incontinence (50%, n = 3), followed by abdominal pain. Only 16.6% (n = 1) were associated with a duplex collecting system. In males, the most common site was the seminal vesicle, observed in 66.6% (n = 2), followed by the urethra in 33.4% (n = 1) of cases. One patient with an ectopic opening into the seminal vesicle had Zinner syndrome. In females, the ectopic site was found to be the vagina in all three patients.

Conclusion: Ectopic ureter is a rare anomaly of the urinary system, often associated with other urinary system anomalies and a few syndromes. Clinical presentations range from the patient being asymptomatic to renal failure; therefore, a high index of suspicion and appropriate imaging are necessary for early diagnosis and timely treatment.
