Brief summary

Rationale: Ureteric injury is a known risk associated with complex gynecological surgery given its variable anatomical course through the pelvis. Ureteric injury is associated with significant morbidity thus methods to reduce surgical complications are important. Objectives: The primary objective is to determine the feasibility of undertaking a four-arm randomized trial to determine the most effective method of introducing cystoscopic-guided intraurethral indocyanine green (ICG) solution for ureteric identification during laparoscopic gynecological surgery. The intended primary outcome of the final study will be surgeon opinion of ease of ureteric identification laparoscopically. Secondary objectives include assessing if improved ureteric visualisation reduces surgical time, reduces additional procedures such as repeat cystoscopy or additional radiological investigations such as CT-IVP and reduces ureteric injury.

Interventions

25mg of Indocyanine Green (ICG) powder (one vial) will be diluted in 10mls of sterile water and 5mls injected into each ureter. Patients will be divided into the following groups: 1. Cytoscopic-guided intraurethral ICG solution injected with advanced ureteric catheter at 3cm and remove ureteric catheter straightaway. 2. Cytoscopic-guided intraurethral ICG solution injected into ureter at 3cm with advanced ureteric catheter and insert ureteric catheter up to 17cm. 3. Cytoscopic-guided intraurethr

Cytoscopic-guided intraurethral ICG solution injected into ureter with advanced ureteric catheter at 10cm while withdrawing completely and removing it. 4. Cytoscopic-guided intraurethral ICG solution injected into ureter at 10 cm with advanced ureteric catheter while withdrawing then reinsert ureteric catheter at 17cm.
