Recently I performed a robotic ureteroureterostomy on a 7-month-old girl with a left ectopic ureter. Her left colon was very dilated with mostly gas and some hard stool proximally. The procedure went well but I wished I had given her laxatives the day before.
Laxatives the night before and the day of robotic surgery could be beneficial for:
- Reimplants: a dilated rectum can interfere with ureteral dissection distally
- Ureteroureterostomies, especially on the left side
- Pyeloplasties: colon has to be reflected on the right and could be in the way on the left side too.
Also, intraoperative and postoperative narcotic use could cause constipation, making it a preventative move to do laxatives before surgery.
Side effects from 2 over-the-counter saline enemas are likely to be negligible.
Here is a short video of the UU complicated by the dilated colon:
