Objective:
To evaluate the value of X-ray fluoroscopy in preventing catheter dysfunction during catheterization of peritoneal dialysis.
Methods:
A total of 168 patients with end-stage renal failure were nonrandomized into group A (the conventional catheterization group) and group B (the conventional catheterization + bedside fluoroscopy group). All patients were followed up for 1 year after the catheterization. Details of the patients' general information, catheter-related complications and incidence of catheter dysfunction were analyzed.
Results:
Hemorrhagic complications occurred in 9 patients (5.36%), including 2 incision hematomas, 4 bloody fluid drainages, 1 bladder perforation and 1 intestinal perforation (1.20%). Dialysate leakages occurred in 4 patients (2.38%): 2 right pleural effusion and 2 scrotal edemas. Infection-related complications (2.98%) in 5 patients were observed: 1 infectious peritonitis and 4 catheter exit infections. All peritoneal dialysis-related infections were cured after the treatment. There was no significant difference in the incidence of mechanical and infectious complications between the two groups (P> 0.05). No immediate catheter dysfunction was found in all patients, but late catheter dysfunction was observed in 14 patients (8.33%), including 9 catheter migrations (5.36%), 5 of which were induced by other reasons (2.98%). Catheter dysfunction in 11 out of the 14 patients occurred within 30 days post-catheterization, whereas 2 occurred over 30 days (caused by constipation). In group A, 12 patients developed delayed catheter dysfunction (11.65%), 10 of which (83.33%) were induced by catheter migration and the other 2 by other reasons. In group B, 2 (11.65%) delayed catheter dysfunctions were observed, including 1 catheter migration and 1 constipation. The incidence of catheter dysfunction in group A was significantly higher than that in group B (P<0.05). The success rate of catheterization in group B was 91.3%.
Conclusion:
Catheter dysfunction is a common complication in peritoneal dialysis. X-ray fluoroscopy during catheter insertion helps to monitor the location of the catheter, which can effectively prevent late catheter dysfunction and increase the success of catheterization in peritoneal dialysis.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
