==Urinary Problems in men and women==
* Both men and women have an increased risk for urinary incontinence as they get older, with men's rates rising steadily and women's rates peaking during menopause.
* The prevalence of incontinence in men of all ages is certainly lower than that for women.
* Women over 70, however, are twice as likely to have urinary incontinence as men of the same age.

==Market Analysis==
* We determined market data to have an idea about the market potential for ureteral stents.
* We have done this modeling for female population in US as women has the higher prevalence rate for urinary incontinence than men in all age groups.
* Prevalence increased with age, from 28% for 30- to 39-year-old women to 55% for 80- to 90-year-old women.
* 18% of respondents reported severe UI.
* The prevalence of severe UI also increased notably with age, from 8% for 30- to 39-year-old women to 33% for 80- to 90-year-old women.
* Among all, 9% reported slight UI, 15% reported moderate UI, 18% reported severe UI, and 58% reported no UI.

====Ureteral stents of various companies====
=====Boston Scientific=====
* Contour VL Variable Length Percuflex Stents<BR>
Inward spiral design of Nautilus Coil minimizes tissue contact for enhanced comfort. Dual variable length coil geometry permits balanced stent positioning to minimize the risk of migration. HydroPlus Coating provides unequalled surface lubricity which reduces friction to minimize risk of buckling during introduction and placement and to reduce risk of trauma and encrustation.
