MRI in the diagnosis of a peritoneal leak in continuous ambulatory peritoneal dialysis

Mechanical problems in continuous ambulatory peritoneal dialysis (CAPD) can result in ultrafiltration failure and disruption of CAPD therapy. The rece ntly described tool of CT peritoneograpby with water-soluble contrast mediu m has the disadvantage of radiation and instillation of nephrotoxic substan ces. We report a child with a peritoneal leak diagnosed by MRI after instil lation of a gadodiamide-dialysate mixture. This method provided good anatom ical detail without radiation or nephrotoxic agents.
