This process can sometimes be seen in the renal pevis (pyelitis cystica or bladder cystitis cystica).
Their presence even in small amounts in markedly alkaline urine is indicative of urinary tract infection with urease producing microorganisms usually Proteus mirabilis, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, or less frequently Corynebacterium urealyticum, responsible for encrusted cystitis and/ or pyelitis (Daudon et al., 2016).

Findings were suggestive of emphysematous pyelitis with an element of obstruction, related to the high density material within the right renal pelvis.
Pyelitis and bronchopneumonia due to or as a consequence of anoxic brain damage, due to or as a consequence of compression asphyxia.
