Pyelitis is related to cystitis and hydronephrosis. An important gene associated with Pyelitis is CRP (C-Reactive Protein), and among its related pathways/superpathways are Innate Immune System and Toll-like receptor signaling pathway. Affiliated tissues include kidney and spinal cord, and related phenotypes are Synthetic lethal with MLN4924 (a NAE inhibitor) and homeostasis/metabolism
