SP538HOW MANY CATHETERS THE PATIENTS NEED DURING THEIR PASSAGE THROUGH PERITONEAL DIALYSIS? OUR EXPERIENCE IN THE LAST 10 YEARS

Abstract

INTRODUCTION: The mechanical complications of the catheter (poor positioning, obstruction, entrapment by omentum) suppose a discomfort for the patient, an overload of work, interfere with the quality of dialysis and can lead to change to hemodialysis The peritoneal self-location catheter is a modification of the Tenckhoff catheter. In the distal tip has an increased diameter of two centimeters, which is the result of adding a weight of 12 grams made of tungsten, to favor the placement in the lower part of the peritoneal cavity, preventing malfunction due to displacement. Analyze the number of catheters that patients have required during their stay in peritoneal dialysis (PD) and causes of replacement. METHOD(S): Retrospective descriptive study of all the catheters implanted during the last 10 years (2009-2018), with a minimum stay time in PD of three months. All were peritoneal self-location catheter, implanted by means nephrologists through minimal laparotomy. Demographic data, the etiology of kidney disease, follow-up time, number of catheters per patient, replacements and causes are collected. RESULT(S): 182 catheters were implanted in 178 patients, 114(64%) men and 64(36%) women. Male /female relations 2:1. Average age 55.26(18-89) years. Mean follow-up 27.8(5-113) months. Etiology of kidney disease: 38.2% glomerulonephritis, 24.7% unknown etiology, 19.1% diabetic, 4.3% chronic pyelonephritis, 7.3%polycystosis, 1.6% vascular, 1.6% other. 98.87% of the patients required a single catheter during their stay in the PD. Four patients required 2 catheters. Causes of replacement: 1 entrapment of omentum 1 leak 2 peritonitis It was not necessary to remove any catheter due to malposition or obstruction. The ratio of catheter x patient was 1,022 CONCLUSION(S): The self-location catheter allows us to provide patients with better treatment quality by reducing the need for replacement, replacement approaching that each patient needs only one catheter in its passage through PD.
