CT-peritoneography in diagnosis of patent processus vaginalis in peritoneal dialysis

Patent processus vaginalis is a congenital condition characterized by persistent communication between the scrotum and peritoneal cavity which is associated with pathologies like congenital hydrocele/hernias. Asymptomatic patent processus vaginalis may become clinically evident in patients undergoing peritoneal dialysis, who may present with unilateral scrotal edema following dialysis. Conventional plain computed tomography (CT) may be difficult to identify the communication, especially if small, and in such cases, CT peritoneography will be useful to detect the patent processus vaginalis.
