Tenckhoff peritoneal dialysis catheters: the use of fluoroscopy in management

Manipulation of the Tenckhoff catheter under fluoroscopic guidance is a useful procedure in patients who undergo chronic ambulatory peritoneal dialysis (CAPD). We reviewed 50 manipulations in 28 patients. There were no significant complications attributable to the procedure. Ten per cent of the manipulations were performed for visceral pain, 40% for malfunction within the first two weeks of catheter placement, and the remaining 50% for malfunction after two weeks of adequate dialysate flow. Overall, an initial success rate of 88% was recorded, and, after long term study, a durable success rate of 58% was demonstrated. Early malfunction (i.e., within the first two weeks) is a more ominous prognostic indicator than previously realized, with only 30% of these manipulations ultimately succeeding vs. 60% of manipulations in late onset catheter failure. Nevertheless, at least one attempt is warranted in manipulation of a malfunctioning Tenckhoff catheter.
