[Two cases of strangulated urethral prolapse].

This is a report of two cases of strangulated urethral prolapse we recently experienced. One patient, a 70-year-old woman, was admitted to our hospital because of dysuria, painful urination, genital mass (phi 3.0 cm) and bleeding. The other patient, 54 years old, visited our department complaining of pain on urination, and genital mass (phi 2.0 cm) and bleeding. Surgical excision was performed for these prolapsed urethra, and in pathological findings, vascular dilation, blood congestion and partial thromboformation were recognized. Their postoperative course was uneventful without recurrence or abnormal urination. Urethral prolapse is defined as the circular eversion of the urethral mucosa through the external meatus. This condition is a relatively uncommon lesion in the literature, but is a common clinical entity in postmenopausal women and prepubertal girls. Most of the urethral prolapses are small and asymptomatic, but if the prolapsed urethra is large, the mass becomes strangulated, and urinary symptoms, pain and bleeding are present. For the treatment of the urethral prolapse, surgical excision has been widely practiced and is successful.
