UROPLASTY HIGHLIGHTS CLINICAL RESULTS FROM A STUDY OF THE
URGENT® PC NEUROMODULATION SYSTEM
Leading Urologist Presents OrBIT Study Results Comparing
Percutaneous Tibial Nerve Stimulation with Pharmaceutical Therapy
at the 2008 American Urological Association Annual Meeting
MINNEAPOLIS, MN, May 21, 2008 – Uroplasty, Inc. (AMEX: UPI), a medical device
company that develops, manufactures and markets innovative proprietary products for the
treatment of voiding dysfunction, today highlighted results from the OrBIT trial of its Urgent®
PC System. The Urgent PC System is a proprietary, minimally invasive percutaneous tibial
nerve stimulation (PTNS) device designed for office-based treatment of urinary urgency, urinary
frequency and urge incontinence, symptoms often associated with overactive bladder (OAB).
Dr. Kenneth M. Peters, Chairman of the Department of Urology at Beaumont Hospital in Royal
Oak, Michigan, leads the OrBIT (OveRactive Bladder Innovative Therapy) multi-center trial
and presented the comparative study’s results today at the 2008 American Urological
Association (AUA) Annual Meeting, being held in Orlando, Florida.
The results confirm that Urgent PC’s PTNS reduces the incidence of voiding episodes at a rate
comparable to tolterodine LA, known by the trade name Detrol® LA (Pfizer), the leading
pharmaceutical therapy for OAB. Highlights from the study include:
• 80% of PTNS patients considered themselves cured or improved, while 55% of tolterodine LA patients considered themselves cured or improved. • Physicians considered 80% of PTNS patients cured or improved, compared with 61% of • The frequency of voiding episodes was reduced in 73% of PTNS patients versus 74% of • No serious adverse events were associated with either treatment. For PTNS, 18.4% of patients reported at least one adverse event related to treatment; 24.5% of patients in the tolterodine LA arm reported at least one adverse event. Constipation and dry mouth were reported less often in the PTNS arm compared to the tolterodine LA arm. “PTNS provides comparable effectiveness to pharmaceuticals and may be considered an alternative to pharmacologic therapy for the treatment of OAB,” Dr. Peters concluded. In an oral presentation, “A Randomized Multi-center Study Comparing Percutaneous Tibial Nerve Stimulation with Pharmaceutical Therapy for the Treatment of Overactive Bladder,” Dr. Peters presented results from a study of 100 patients conducted in 11 U.S. centers. These
patients were randomized to either PTNS treatment with the Urgent PC, or to tolterodine LA.
All patients in the study were diagnosed with urinary frequency at eight or more voids per day.
Patients randomized into the PTNS treatment were treated weekly for 12 consecutive weeks,
while patients randomized into the pharmacologic therapy were given a 90-day prescription for 4
mg daily. All patients completed voiding and bladder control diaries and questionnaires at
baseline and after their 12-week follow-up.
“These results demonstrate that the Urgent PC is an effective and viable non-drug option for
treating the urinary symptoms often associated with overactive bladder,” said Dave Kaysen,
President and Chief Executive Officer of Uroplasty, Inc. “Leading urologists across the country
have been adding PTNS to their armamentarium for OAB treatment, reporting excellent
outcomes and high patient satisfaction. We are delighted to have the OrBIT results validate
Urgent PC’s effectiveness compared to drugs and minimal side effects and expect that adoption
will continue to improve, especially as additional clinical evidence emerges.”

About the Urgent PC Neuromodulation System
The Urgent PC neuromodulation system is a proprietary, minimally invasive nerve stimulation
device designed for office-based treatment of urge incontinence, urinary urgency and urinary
frequency, symptoms often associated with overactive bladder. Application of neuromodulation
therapy targets specific nerve tissue and disrupts the signals that lead to these symptoms.
Uroplasty sells the Urgent PC system in the United States, Canada, and countries recognizing the
CE mark. Outside of the United States, Urgent PC is also indicated for the treatment of fecal
incontinence.
