Use of Pedometer Following Radical Cystectomy


This is a study to evaluate whether use of a pedometer following radical cystectomy decreases post-operative narcotic use and time to return of bowel function.

Detailed Description

This is a randomized controlled prospective study looking at the effect of using a pedometer with graduated step-count goals following radical cystectomy on rate of ileus, return of bowel function and post-operative narcotic use. Subjects will be randomized into a control group or study group. The control group will receive standard of care, with information provided regarding the importance of ambulation following surgery. The study group will receive a pedometer with graduated step-count goals from post-operative day 0 to post-operative day 21. Both groups will be given a standardized post-operative narcotic regimen, and will be asked to record initial passage of flatus and first bowel movement. Subjects will remain on the study until post-operative day 21.


  • Behavioral: Use of a pedometer following surgery
    • Subjects in the study group will receive a pedometer with graduated step count goals as discussed in arm description.
  • Behavioral: Standard of care
    • Subjects in the control group will be counseled on the importance of ambulation during their pre-operative visit.

Arms, Groups and Cohorts

  • Experimental: Pedometer Group
    • This group will be given a pedometer following radical cystectomy. Subjects in the experimental group will have a graduated step-count goal as follows: POD 0-2: 1,000/day. POD 3-6: 2,000/day. POD 7-9: 3,000/day. POD 10-14: 4,000/day. POD 14-21: 5,000
  • Active Comparator: Control group
    • This is the control group. Following radical cystectomy subjects in the control group will receive standard of care, which includes counseling regarding the importance of ambulation following surgery.
