Abstract:

Ｏｂｊｅｃｔｉｖｅ：To assess the diagnostic value of the CT peritoneography for localized subcutaneous edema during continuous ambulatory peritoneal dialysis (CAPD).
Ｍｅｔｈｏｄｏｌｏｇｙ：We performed a prospective analysis of continuous collecting subjects in our nephrology department who occurred localized subcutaneous edema when accepted CAPD during March 2015March 2016.Using Philips Brilliance Plus 64 CT scan. The conventionally CT was obtained. Then 50 mL nonionic contrast medium (Iopamidol) was mixed with 2L dialysate and infused into the peritoneal cavity via Tenchkoff catheter.Peritoneography phase scanning was obtained 30 mins later.Then diagnosis was made.The urine volume and ultrafiltration volume in 24h before and after CT Peritoneography were compared using paired t test.
Ｒｅｓｕｌｔｓ：42 out of 425 followup cases were successfully incorporated into research. Abnormal findings were found in 35 cases (833%) including inguinal hernias 18 cases, umbilical hernia 2 cases, incisional hernia one case, leaks in catheter tunnel 2 cases, navel subcutaneous leakage 6 cases, retroperitoneal leakage 6 cases, retroperitoneal leakage accompanied with subcutaneous leakage one case. Parts of them were confirmed by surgical operation. There was no statistically significant difference in urine volume and ultrafiltration volume in 24h before and after CT Peritoneography (P＞005).
Ｃｏｎｃｌｕｓｉｏｎ：CT peritoneography with a great clinical value can provide accurate diagnosis for localized subcutaneous edema during CAPD, demonstrate anatomical information regarding the etiology, location, and size, and also help us to make treatment planning.
