Ureteral Jets and Patient Positioning Study

Purpose

The objective of the study is to identify the relationship between patient position during surgery and time to confirmation of ureteral patency on cystoscopy.

Conditions

  • Ureteral Injury

Detailed Description

Patients will be randomized to one of two arms: 0 degree supine position and 10-20 degree angle in reverse Trendelenburg. Our working hypothesis is that positioning a patient in 10-20 degree angle reverse Trendelenburg will result in shorter time to confirmation of bilateral ureteral patency and shorter total cystoscopy time, without a change in delayed diagnosis of ureteric injury. Primary outcome: time to confirmation of bilateral ureteral patency Secondary outcome: total cystoscopy time, need for alternative modalities to aid in ureteral efflux visualization, delayed diagnosis of ureteric injury (evaluated 6 weeks postoperatively via chart review)
