Causes
- Pyonephrosis is commonly caused by bacteria as well as fungi like, Enterococcus spp., K. pneumoniae, Candida spp., S. aureus, P. mirabilis, P. aeruginosa and Group B Streptococcus.[1]
- Accumulation of pus as a result of an ongoing upper urinary tract infection (acute pyelonephritis) combined with inability to drain due to obstruction of the renal collecting system results in pyonephrosis.
- The risk factors associated with pyonephrosis include:
- Immunosuppression e.g., diabetes mellitus, AIDS, renal failure, renal transplantation.
- Local factors that compromise the genitourinary tract, like nephrolithiasis, congenital obstructing lesions, neurogenic bladder, pregnancy, long-term indwelling catheters, genitourinary procedures.
