Abstract:
Atypical mycobacteria remain a rare cause of peritoneal dialysis catheter-related tunnel infection (TI) and poses serious risk because of the resistant nature to most antibiotic therapy. Non-tubercular mycobacterial infections lead to chronicity requiring peritoneal dialysis catheter removal. We report an 82-year-old male, with diabetic nephropathy who had a coinfection with Staphylococcus hominis and Mycobacterium abscessus who presented with pus discharge at exit site and TI. He was treated with relocation of the extraperitoneal part of the catheter with a new exit site without catheter removal and multidrug mycobacterial therapy.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
