A urethral caruncle is a hyperplasia of the female urethra, usually at 6 o'clock with prolapse and induction of irritative symptoms. A circular urethral caruncle is also known as urethral prolapse [fig. circular urethral caruncle].

Etiology of Urethral Caruncle
Urethral caruncles are most commonly found in postmenopausal women. Additional risk factors are pelvic floor dysfunction and micturition with subvesical obstruction (abdominal straining).
Signs and Symptoms
A urethral caruncle appears as a pedunculated hemorrhagic mucosal tumor, based mostly on the dorsal urethral. Furthermore, irritative micturition disorders, bleeding or local pain may be present.
Treatment of Urethral Caruncles
The clamping of the caruncle allows easy handling. A circular incision of the mucosa is done at the base of the caruncle. The basis of the caruncle is ligated and the caruncle is resected. The
mucosa is adapted with 4-0 sutures.
There are also reports of good results with a simple ligation of the caruncle without incision or tissue removal, which can be done in the office (Park and Cho, 2004).
