Indwelling vs Intermittent Catheterization Pilot Study

Patients in the experimental group will receive foley catheter upon admission, aseptically. The catheter will be discontinued on the morning following surgery. At TOH most (\>75%) hip fractures are treated within 48 hours of admission and 95% within 72 hours and hence the indwelling catheter is likely to stay in place for 3-4 days.

"Patients randomized to the intermittent catheterization group will have their PVR monitored every 8 hours pre-operatively. If PVR\>400 mL, an intermittent catheter will be used. If PVR\> 400 mL greater than 3 times pre-operatively, an indwelling catheter will be placed the fourth time. The indwelling catheter will be removed the morning of post-op day 1.~It is expected that a small percentage of patients in either group will not have a PVR\>400 mL preoperatively.~These patients will not be catheterized but will remain in the study. Post-operatively, both treatment groups will have their PVR monitored for 24 hours, or until PVR is less than 200 mL. If PVR\>400 mL and the patient is not able to void further, intermittent catheterization will be done every six hours as needed. If post-operative PVR\>400 mL greater than 3 times post-operatively, an indwelling catheter will be placed the fourth time."
