Cobb's collar: a rare cause of urinary retention.

Ottavio Adorisio, Francesca Bassani, Massimiliano Silveri

Research output: Contribution to journalArticlepeer-review


Cobb's collar is a membranous stricture of the bulbar urethra, often misdiagnosed, potentially leading to acute urinary retention, upper urinary tract dilations, enuresis, infectious diseases, poor streaming and haematuria. A 14-year-old boy with a history of previous hospitalisations came to our attention. A Cobb's collar was diagnosed and successfully managed with a videoendoscopic one-step approach. Although extremely uncommon, paediatric urologists must be aware of this congenital anomaly. A correct and timely diagnosis and endoscopic management may affect positively the clinical onset of these patients avoiding major urethral surgery and preserving renal and bladder function.
