Perioperative Physical Activity (Pedometer)

Frailty Study


CAUTI Microbiome

Perioperative Physical Activity (Pedometer)

Prospective Randomized Study of Exercise in Patients Undergoing Urologic Surgery

Inclusion Criteria:

  • Adult patients scheduled for operative procedure with an inpatient postoperative stay

  • Willing and able to give blood samples, complete a questionnaire, fill out the step log, and return to clinic for 1st post-operative appointment

Exclusion Criteria:

  • None


Patients are given a pedometer and asked to record their daily steps in a log. The purpose of this study is to determine if pedometers can aid in increasing patients' physical activity during the perioperative period.
