Adverse factors on nonenhanced abdominal CT for long-term continuous ambulatory peritoneal dialysis: a comparative study between patients who withdraw from and maintain long-term peritoneal dialysis
PURPOSE: To investigate the imaging features of patients with long-term continuous ambulatory peritoneal dialysis (CAPD) on nonenhanced abdominal CT and to identify adverse factors for long-term CAPD. METHODS: A total of 109 patients with less than 5 years of CAPD for peritoneal ultrafiltration fail...

description | PURPOSE: To investigate the imaging features of patients with long-term continuous ambulatory peritoneal dialysis (CAPD) on nonenhanced abdominal CT and to identify adverse factors for long-term CAPD. METHODS: A total of 109 patients with less than 5 years of CAPD for peritoneal ultrafiltration failure who switched to hemodialysis (withdrawal group) and 23 patients with more than 10 years of CAPD (long-term group) were retrospectively enrolled. Nonenhanced CT manifestations in both groups were compared, including thickening and calcification of the parietal peritoneum, calcification of the mesangial margin and free margin of the small intestine wall, and calcification of the mesentery and abdominal aorta. A risk stratification model was proposed based on CT manifestations with statistically significant differences. RESULTS: The presence of the following CT findings was significantly different between two groups: extensive thickening of the parietal peritoneum (78.9% vs. 21.7%, P < 0.01); severe calcification of the parietal peritoneum (60.6% vs. 8.7%, P < 0.01); calcification of the mesentery (32.1% vs. 4.3%, P < 0.05); and calcification of the free margin of the small intestine wall (49.5% vs. 13.0%, P < 0.05). However, there was no significant difference in calcification of the mesangial margin of the small intestine wall (40.3% vs. 30.4%) or in abdominal aortic calcification (56.9% vs. 61.1%) (P > 0.05). The area under the receiver operating characteristic curve (AUC) was 0.906 (sensitivity 87.6% and specificity 82.6%). CONCLUSION: Extensive thickening of the parietal peritoneum, severe calcification of the parietal peritoneum, and calcification of the mesentery and the free margin of the small intestine wall are adverse factors for long-term CAPD. |
