/* The market need */
The number of ureteral stents used in patients with stones 2 cm or less treated with ESWL is significant in spite of the lack scientific evidence in support of this practice. Of 1,029 urologists returning surveys, for patients with renal pelvic stones 10, 15 or 20 rnm treated with ESWL, routine stent placement was preferred by 25.3%, 57.1 % and 87.1 %, respectively. Urologists recommend using ureteroscopy rather than ESWL for distal ureteral calculi 5-1 0 mm.
===Market Data==
* We determined market data to have an idea about the market potential for ureteral stents.
* This data is for women in US in different age groups and having different level of severity.
* 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.
