[TWO CASES OF URETHRAL PROLAPSE MISDIAGNOSED AS PELVIC ORGAN PROLAPSE]

We experienced two cases of urethral prolapse misdiagnosed as pelvic organ prolapse. One patient, an 87-year-old woman, was referred to us from a gynecological clinic with a supposed uterine prolapse. The other patient, an 84-year-old woman, was referred to us from the Department of Urology in a general hospital with a supposed recurrence of cystocele following a transvaginal mesh repair. We diagnosed both of them as having a urethral prolapse through pelvic examination and cystoscopy. Both patients were treated uneventfully with the four-quadrant excisional technique. Urethral prolapse is a relatively rare disease and as such, urologists and gynecologists may have little exposure to the symptoms in a clinical setting, resulting to misdiagnosis or delayed diagnosis. We discussed the differential diagnosis of urethral prolapse.
