“…5 Intervention has shown improvement in bladder irritability, VUR, urethral calibre and uroflowmetry as well as a reduced presentation with UTI and enuresis. 5,7 This is the first reported case of a Cobb's collar in association with VACTERL. VACTERL was first described in 1973 and is defined by the presence of at three of the described abnormalities, with anorectal malformations and trachea-oesophageal fistulae considered core components.…”

SUMMARY Cobb's collar is a rare intraluminal congenital cause of bulbar urethral obstruction that is commonly mislabelled congenital obstructive posterior urethral membrane (COPUM) but may be distinguished from this endoscopically as it has no connecting folds to the verumontanum. In this report, Cobb's collar is described for the first time in association with the VACTERL syndrome. The abnormality was diagnosed and treated by diathermy and dilatation at the time of endoscopic evaluation, with improvement of vesicoureteric reflux on micturating cystourethrogram and renal ultrasound.

“…Chronic urinary retention and bilateral hydronephrosis may be a presenting feature in some patients, as in our case. [ 10 11 ] These adult patients may also complain of poor ejaculation. [ 5 ] Late presentation of Cobb's collar (caused by a persistence of urogenital membrane) can be differentiated from acquired stricture by the absence of the characteristic folds between COPUM anomalies and verumontanum.…”

Most urethral strictures arise from iatrogenic, traumatic, or inflammatory causes. We report the familial occurrence of a congenital bulbar urethral stricture in two brothers. Retrograde and voiding cystourethrography was performed. A Cobb's collar was diagnosed after radiological and endoscopic evaluation in both cases and was successfully managed with urethroplasty. Cobb's collar is a rarely recognized cause of a membranous stricture of bulbar urethra that can lead to several urinary problems. In cases of adolescent and young adults presenting with symptoms of progressive urinary obstruction and enuresis with or without urinary tract infection, Cobb's collar can be seen as a minor constriction in the bulbar urethra, but is not frequently symptomatic, and the familial occurrence of such a stricture is even rarer.

“…There is no information related to male cases in the literature, however, for differential diagnosis, anterior urethral pathologies are important. When anterior urethral pathologies are examined, congenital urethral polyp in the anterior urethra, fossa navicularis pathologies (stenosis, Guerin's sinus), anterior urethral valve, syringocele (dilatation of Cowper's gland ducts), congenital bulbous urethral stricture, condyloma accuminatum, and especially botryoid sarcoma polyps should be taken into the consideration in the differential diagnosis (5,6,7,8). Definite diagnosis of squamous cell papilloma is made by careful pathological investigation.…”

Urethral squamous cell papilloma is a benign lesion commonly presenting with lower urinary tract symptoms, such as dysuria and intermittent poor urinary flow. Surgical excision and careful pathological investigation are required for definite diagnosis and treatment. The probability of recurrence is fairly low. These lesions are generally observed in the urethra in post-menopausal women. This paper presents a case of squamous cell papilloma in the male anterior urethra in an 18-year-old male patient, who underwent surgical excision, and a literature review. Keywords: Papilloma, Tumor, Urethra Üretranın skuamöz hücreli papillomu genellikle dizüri ve aralıklı idrar akış hızında azalma gibi alt üriner sistem semptomları ile bulgu veren benign lezyonlardır. Kesin tanı ve tedavi için cerrahi eksizyon ve dikkatli bir patolojik inceleme gerekmektedir. Nüks riski oldukça düşüktür. Bu lezyonlar genellikle menopoz sonrası kadınların üretrasında gözlenmektedir. Fakat, bu yazıda literatür eşliğinde erkek anterior üretrası kaynaklı skuamöz hücreli papillomu olan ve cerrahi eksizyon yapılan 18 yaşında erkek hasta sunulmaktadır.
