Trendelenburg, Abdominal Insufflation and Time to Completion of Cystoscopy

Trendelenburg, Abdominal Insufflation and Time to Completion of Cystoscopy A Prospective Randomized Trial

Objective:

The investigators seek to compare the efficiency of the cystoscopy with two interventions:

1. patient position during the cystoscopy (Trendelenburg (head down) or flat)
2. Abdominal insufflation (insufflation versus no insufflation)

Study Overview

• Status: Completed
• Conditions: Bladder Function; Bladder Integrity; Ureteral Integrity; Ureteral Function
• Intervention / Treatment: Other: Flat position; Other: Trendelenburg position; Device: Insufflation

Detailed Description

This is a randomized controlled trial assessing time to completion of cystoscopy in seconds after minimally invasive gynecologic surgery.

The investigators seek to compare the efficiency of the cystoscopy with two interventions:

1. patient position during the cystoscopy (Trendelenburg (head down) or flat)
2. Abdominal insufflation (insufflation versus no insufflation).

Both interventions are used as usual care and depend on surgeon preference without evidence why one would be faster at completing the cystoscopy. Also note that these two interventions are performed multiple times during the surgery itself and outside the cystoscopy procedure routinely. The investigator's main objective is to assess which intervention or combination of interventions is more efficient.
