Computed tomographic peritoneography in the investigation of abdominal wall and genital swelling in patients on continuous ambulatory peritoneal dialysis.

Computed tomography (CT) of the abdomen following the intraperitoneal instillation of water soluble contrast medium was employed in seven patients with lower abdominal wall and/or scrotal swelling which had developed whilst on continuous ambulatory peritoneal dialysis. In all seven patients contrast medium was seen to leak into the tissues of the anterior abdominal wall from the site of insertion of the Tenckhoff catheter, and in two male patients was shown to track into the scrotum (in one via a patent processus vaginalis). This technique gave accurate anatomical detail which was useful for planning subsequent management.
