Summary
Congenital bulbar urethral narrowing, or Cobb's collar, is frequently associated with syringoceles in boys. This finding suggests a potential shared origin, though urethral narrowing may sometimes be incidental.
Area of Science:
- Pediatric Urology
- Urethral Abnormalities
- Congenital Malformations
Background:
- Syringoceles are rare congenital cystic dilatations of the prostatic utricle.
- Congenital narrowing of the bulbar urethra (Cobb's collar) is a less common finding.
Purpose of the Study:
- To investigate the association between congenital bulbar urethral narrowing and syringoceles in pediatric patients.
- To explore the potential etiological relationship between these two urethral abnormalities.
Main Methods:
- Retrospective review of 11 boys with suspected urethral abnormalities.
- Analysis of cystogram (10 patients) and video endoscopy (9 patients) findings.
- Detailed assessment of the relationship between syringoceles and Cobb's collar.
Main Results:
- A Cobb's collar was identified in 7 of 9 boys examined endoscopically, often located near the syringocele.
- Syringocele and bulbar urethral narrowing were observed in 6 of 10 patients on cystogram.
- The external sphincter was consistently found separate from the syringocele.
Conclusions:
- Syringoceles appear frequently associated with Cobb's collar, supporting a possible common origin from the urogenital membrane.
- Bulbar urethral narrowing might be an incidental finding in some cases of syringocele.
