This study reports three rare cases of blind-ending bifid ureter, a congenital anomaly of the upper urinary tract. These findings contribute to understanding this uncommon condition in urology.

Area of Science:

  • Urology
  • Congenital Anomalies
  • Medical Imaging

Background:

  • Blind-ending bifid ureter is an exceptionally rare congenital anomaly affecting the upper urinary tract.
  • Understanding the presentation and diagnosis of this condition is crucial for effective patient management.

Observation:

  • Three distinct cases of blind-ending bifid ureter are presented, involving patients aged 53 to 61.
  • Diagnostic imaging modalities, including Kidney-Ureter-Bladder X-ray, drip intravenous pyelography (DIP), and retrograde pyelography, were utilized.
  • Presenting symptoms included right lumbal colic pain and asymptomatic microhematuria.

Findings:

  • Case 1: A 53-year-old male presented with right lumbal colic pain, with imaging revealing a right ureteral stone and a left blind-ending bifid ureter.

  • Case 2: A 61-year-old female with asymptomatic microhematuria was diagnosed with a right blind-ending bifid ureter via retrograde pyelography.
  • Case 3: A 57-year-old female presented with asymptomatic microhematuria, and DIP confirmed a left blind-ending bifid ureter.
  • A total of 68 cases of blind-ending bifid ureter reported in Japan, including these three, were compiled.

    • Implications:

    • The findings highlight the importance of advanced imaging in diagnosing rare urinary tract anomalies.
    • This case series expands the documented cases of blind-ending bifid ureter, aiding in the understanding of its prevalence and clinical spectrum.
    • Further research into the etiology and long-term outcomes of this anomaly is warranted.
