2. What is Urinary Incontinence?  Urge Incontinence Involuntary loss of urine associated with abrupt and strong desire to void  Stress Incontinence Involuntary loss of urine during coughing, sneezing, laughing, etc  Overflow Incontinence Involuntary loss of urine associated with over distension of bladder  Functional Incontinence No recognition of need to void, inability to make it to the toilet in time

3. Causes  Neurological disorders Parkinson’s, Multiple Sclerosis, Alzheimer‘s Stroke, brain tumor, spinal injury  Hormone imbalances Menopause  Prostate cancer  Loss of muscle tone Childbirth, old age

4. Prevalence  13 million people in the U.S.  10-35% of adults  50% of the 1.5 million residents in nursing homes  leading cause of admission to a nursing home  may lead to pressure sores and ulcers, possibly resulting in secondary infections http://www.emedicine.com/med/topic3085.htm

5. Treatment Options  Surgery  Sling  Catheterization  Artificial Urinary Sphincter  Exercises  Electrical stimulation  Timed voiding/ bladder training  Medication

6. Available External Devices  Penile clamp Puts external pressure on the male urethra  Sling completely inside your body places pressure on the urethra, reducing the possibility of urine leakage  Absorbent pads

7. Available Internal Devices  Catheter Indwelling catheter ○ Drainage bag secured to inside of leg Intermittent (short-term) catheter Suprapubic catheter ○ placed directly into the bladder through the abdomen  Mama-sure Ultima Internal electrical stimulator  AMS 800 artificial urinary sphincter implantable, fluid-filled, solid silicone elastomer

8. Specifications Desired  Comply with industry standards for urological medical devices  Be able to remain indwelling for 30 days  Easily operated by patient with disabilities  Allow emptying of the bladder when desired  Prevent urine flow when not desired  Provide an indication of the status of the bladder.

9. Completed Work  Set up with appointment with Dr. Doug Milam  Researched externally controlled implantable stimulation device

10. Current Work  Continuing to correspond with Dr. Katherine Cameron  Meeting with Dr. Doug Milam at 5:00pm

11. Future Work  Interview patients with incontinence control devices to determine needs and desires  Establish a way to indicate bladder status
