Exit site granuloma is one the most frequent complications associated to peritoneal dialysis catheter, which usually solves by medical treatment, but sometimes it only solves by surgery. In the following reports we present a clinical case which represents an example of this. [ABSTRACT FROM AUTHOR]

Background: Magnesium and phosphorus are one of the electrolytes whose balance is altered during advanced chronic renal failure (CRD-V). It has already been reported in the literature that there is a progressive increase in urinary electrolyte excretion in CRD-V in relation with the glomerular filtration rate reduction, but it has not been extensively studied yet for these divalent ions. Therefore we decided to perform a study for evaluating compared values of urinary and peritoneal fractional excretion of these divalent ions (magnesium and phosphorus) among patients on peritoneal dialysis with residual diuresis (CRDV), stage III - chronic renal failure, and healthy volunteers. Results: Urinary fractional excretion (FEu) of magnesium (Mg) and phosphorus (P) were significantly (p= < 0.05) lower in healthy volunteers (FEuMg: 3 ± 1%, FEuP: 9 ± 0.5%), and significantly higher in CRD-V (FEuMg: 30 ± 4%, FEuP: 40 ± 0.2%). Regarding peritoneal fractional excretion (FEp) of magnesium and phosphorus, they were significantly higher (p= < 0.05) (FEpMg: 36 ± 5%, FEpP: 62 ± 9%) than the urinary ones in the same population: CRD-V. Conclusion: Magnesium and phosphorus urinary fractional excretion values were significantly higher in the CRD-V group, while these values were significantly lower than the peritoneal ones in the same population: CRD-V.
