With an endopyelotomy stent, the junction between the uterus and the pelvis is temporarily drained into the bladder. This has to be done because of a stricture incision.
This part of the uterus does not have any side ports. This is to prevent uterine wall ingrowths and post-operative narrowing of the uterine lumen.
The Endopyelotomy Stent, which is made of radiopaque polyurethane, comes in a sterile package that you can peel open. It’s made to be used just once and then thrown away.
