Nephrology:
16. Compromised renal function defined as serum creatinine > 2.0 mg/dl.
17. Hydronephrosis (Grade 2 or higher).
Oncology:
18. Prostate cancer testing:
If PSA is > 2.5 ng/ml and = 10 ng/ml with free PSA <25%, prostate cancer for the
subject must be/had been ruled out through a negative biopsy prior to enrollment
- Males 50-59 years - PSA is >2.5 ng/ml and =10 ng/ml with free PSA <25%,
- Males 60+ years - PSA is >4 ng/ml and =10 ng/ml, with free PSA <25%
19. History of confirmed malignancy or cancer of the prostate or bladder; however, high
grade prostatic intraepithelial "PIN" is acceptable.
20. History of cancer in non-genitourinary system that is not considered cured (except
basal cell or squamous cell carcinoma of the skin). A potential participant is
considered cured if there has been no evidence of cancer within five years of
enrollment.

required.

26. Use of antiplatelet or anticoagulant medication except low dose aspirin (<100mg/day)
within 10 days prior to treatment.

30. Diagnosed or suspected primary neurologic conditions such as multiple sclerosis or
Parkinson's disease or other neurological diseases known to affect bladder function,
sphincter function or poor detrusor muscle function (< 25% of accepted and established
nomograms).
General:
31. Currently enrolled in any other pre-approval investigational study in the US (does not
apply to long-term post-market studies unless these studies might clinically interfere
with the current study endpoints (e.g., limit use of study-required medication, etc.).
32. Any significant medical history that would pose an unreasonable risk or make the
subject unsuitable for the study.
33. Inability to provide a legally effective "Informed Consent Form" and/or comply with
