Summary
We studied 32 clinically continent women with severe prolapse. We found evidence of occult stress incontinence in 10 of these women after reduction of the prolapse with a ring pessary. Our results, confirming the work of others, suggest that a high proportion of women with severe genito-urinary prolapse are at an increased risk of occult stress incontinence that could result in incontinence after surgery for prolapse. Urodynamic studies after restoring anatomy with a ring pessary may identify these women needing anti-incontinence procedures at the time of surgical repair of the prolapse.
