Any one with a retroverted uterus (literally backwards) and using the Estring Vaginal Silicone Ring?

... Patients problem is inserting the ring properly for it to reach the area of body to relieve the upper to mid portion of urethra (thus relieving urogenital atrophy). Would like to hear from someone out there please. Can not think of any other product that provides aid to my patient's condition. All comments are welcome; but sometimes wish the ring came in a smaller size to help with patients better placement of the silicone ring. Thanks.
