Urometrocolpos associated with retroiliac ureter

Area of Science:

• Pediatric Urology
• Congenital Abnormalities
• Vascular Anatomy

Background:

• An 8-year-old female presented with acute abdominal pain, necessitating urgent clinical evaluation.
• Congenital anomalies of the genitourinary tract can present with diverse and complex clinical manifestations.

Observation:

• Physical examination identified a left hypoplastic kidney with its ureter abnormally draining into the lower vagina.
• The vagina was obstructed by an imperforate hymen, leading to urometrocolpos.
• Right hydronephrosis was initially suspected to be caused by extrinsic compression from the urometrocolpos.

Findings:

• Further investigation revealed the right ureter followed a retroiliac course.
• The right ureter was compressed by a unique U-shaped loop of the iliac artery at the ureteropelvic junction.
• The anomalous iliac artery extended superiorly to the level of the second lumbar vertebra.

Implications:

• This case highlights a complex interplay of genitourinary malformations and vascular anomalies.
• Accurate diagnosis requires advanced imaging to delineate the precise anatomical abnormalities.
• Understanding these rare conditions is crucial for effective surgical management and improved patient outcomes in pediatric urology.
