Cecoureterocele: morphology and clinical correlations

Area of Science:

• Urology
• Pediatric Surgery
• Anatomy

Background:

• Cecoureteroceles are rare congenital anomalies.
• Understanding their anatomical basis is crucial for managing associated urinary incontinence.

Purpose of the Study:

• To investigate the detailed structure of a cecoureterocele and its impact on the vesicourethral sphincter.
• To correlate necropsy findings with clinical presentations of urinary incontinence.

Main Methods:

• Macroscopic and microscopic examination of serial sections of a cecoureterocele, bladder, and urethra from a neonatal necropsy specimen.
• Correlation of anatomical findings with clinical data from two patients with similar conditions.

Main Results:

• The cecoureterocele and its extension were found to be amuscular.
• The bladder neck and urethral sphincters (involuntary and voluntary) showed muscle attenuation or absence beneath the cecoureterocele.
• These structural deficits were linked to urinary incontinence in living patients post-excision.

Conclusions:

• The amuscular nature of the cecoureterocele and associated sphincter deficiencies contribute to urinary incontinence.
• Surgical management of cecoureteroceles must consider the underlying structural abnormalities to prevent or address incontinence.
