What exactly is peritoneal dialysis catheter manipulation?

Repositioning: Usually using an endoscopic surgery. Usually done due to malfunction of the peritoneal tube i.e. Not draining fluid well. Change of position makes for a better chance for the catheter to work better.

Dr Kandarpa agreed

PD Catheters: This is a procedure that is used to get a malfunctioning catheter to work again. There are many different ways this is done - putting a wire down the catheter or putting other devices down the catheter. Ask you doctor for a more thorough explanation.

Dr Fowler and another doctor agreed

Catheter move: Peritoneal dialysis catheter manipulation refers to a procedure done by an experienced surgeon or an experienced interventional radiologist who will adjust the internal position within your abdomen of the internal aspect of the PD catheter. The catheter is not removed and replaced. Rather the inner tube only is moved within the abdomen to allow better flows of the dialysis fluid.
