Resumen

El collar de Cobb es un estrechamiento congénito de la uretra bulbar con presentación clínica y grado de obstrucción variables.

Presentamos un caso clínico de un niño de 13 años de edad con hematuria macroscópica terminal y uretrorragia postmiccional. La cistoscopia identificó una membrana en la uretra bulbar, inmediatamente distal al esfínter externo, y vasos prominentes en la uretra prostática. La incisión endoscópica transuretral realizada fue curativa.

Los autores hacen también una breve revisión de la embriopatogenia, clínica y tratamiento de esta patología rara.

Abstract

The Cobb’s collar is a congenital narrowing of the bulbar urethra with variable clinical presentation and obstruction grade.

Herein we report a clinical case of a 13-year-old boy presenting terminal macroscopic haematuria and post-mictional urethral bleeding. At cystoscopy a membrane on the bulbar urethra distal to the external sphincter and prominent vessels in the prostatic urethra were found. Transurethral endoscopic incision was carried out with no complications or recurrence at 9-month follow-up.

The authors briefly review the embryopathogenesis, clinical features and treatment of this uncommon anomaly.

Key words:
Cobb’s collar
Haematuria
Urethral bleeding
