[Simple orthotopic ureteroceles in children]

Area of Science:

• Urology
• Pediatric Urology
• Radiology

Background:

• A simple orthotopic ureterocele arises from a single ureter's terminal portion entering the bladder.
• These are frequently bilateral and less common in children compared to heterotopic ureteroceles associated with ureteral duplication.

Observation:

• The study reports six cases of simple orthotopic ureteroceles.
• Classical radiological signs were reviewed.
• Three unusual presentations were identified and emphasized.

Findings:

• One case involved a simple orthotopic ureterocele complicated by calculi (stones).
• Another presented with ureterocele prolapse into the posterior urethra, causing dysuria in a male patient.
• A third case demonstrated a simple orthotopic ureterocele within a blind ureter associated with polycystic kidney disease, with contralateral primary obstructive mega-ureter.

Implications:

• These findings expand the understanding of simple orthotopic ureterocele presentations.
• Recognition of these rare complications is crucial for accurate diagnosis and management in pediatric urology.
• The study underscores the importance of thorough radiological assessment in complex pediatric urinary tract anomalies.
