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

The patient will be placed in an angle on the surgical table during cystoscopy.
Banner University Medical Center Phoenix
Phoenix, Arizona, United States
time to confirmation of bilateral ureteral patency
time between initiation of cystoscopy and visualization of second ureteral jet in minutes
Time frame: 1 day
total cystoscopy time
Total time of cystoscopy
Time frame: 1 day
need for alternative modalities to aid in ureteral efflux visualization
After 10 minutes of no jet, it is okay for the surgeon to use alternative methods, including dextrose, sodium fluorescein, indigo carmine, IV diuretics, etc.
Time frame: 1 day
delayed diagnosis of ureteric injury
evaluated 6 weeks postoperatively via chart review
Time frame: 6 weeks after surgery
