required diary, follow up visit and testing schedules

4. Ambulatory without the aid of walking assistance a majority of the time (cane, walker
etc.) and able to use toilet without assistance

5. Post-void residual (PVR) ≤ 100 ml NOTE: Subjects with a single PVR of >100 ml
followed by two consecutive PVR measurements of ≤100 ml may be included in the study.

6. Ability and willingness to self-catheterize in case this is necessary

7. Bladder Diary Criteria: over the 3 days the following outcomes:
