Fluoroscopic Guided Peritoneal Dialysis Catheter Placement: An Analysis Of Pelvic Catheter Positioning And Early Catheter Flow Dysfunction, David Clark
Electronic Thesis and Dissertation Repository
Fluoroscopic peritoneal dialysis catheter (FPDC) positioning has not been thoroughly evaluated. Using a retrospective cohort of adult patients who underwent FPDC insertion in London, Ontario (Feb 1, 2010 - Aug 1, 2017); we retrieved procedural radiographs measuring the level of intraabdominal radiocontrast to pubic symphysis (IRPS), and catheter tip to pubic symphysis (CTPS). The median (Q1-Q3) distance (millimeters) of IRPS was larger in females [35(25-44)] than males [28(19-37); P=0.001]; but this distance was not associated with variables: Age (years), BMI (Kg/m2), Race, PKD, abdominopelvic surgeries, in correlation/regression analyses. CTPS distance increased with BMI [(β; 95% Confidence Interval …
Noninvasive Quantification Of Tissue Sodium Concentration In The Kidney Disease Spectrum Using 23na Magnetic Resonance Imaging, Fabio R. Salerno
Noninvasive Quantification Of Tissue Sodium Concentration In The Kidney Disease Spectrum Using 23na Magnetic Resonance Imaging, Fabio R. Salerno
Electronic Thesis and Dissertation Repository
Chronic kidney disease (CKD), especially when requiring kidney replacement therapy (hemodialysis (HD) and peritoneal dialysis (PD)), is associated with extracellular water expansion with increased total body sodium. Sodium can also be accumulated in tissues independently of extracellular water. Sodium-23 magnetic resonance imaging (23Na MRI) can quantify the concentration of sodium nuclei in tissues. Applied to the human leg, quantification of tissue sodium concentrations mainly at the skin and muscle level is possible. We hypothesized that increased tissue sodium concentrations exert toxic effects in CKD and dialysis. We aimed to (1) compare tissue sodium concentrations in adults, children and …
