title: [Chronic pyelonephritis. Synopsis of laboratory values and ultrasound lead to diagnosis].
abstract: Bacteria or their antigens persisting in the kidneys may induce the classical type of chronic pyelonephritis (CP), which progresses slowly, and may finally result in end-stage renal failure requiring dialysis. Pyelonephrogenic strains enter uro-epithelial and renal epithelial cells--where they accumulate--or may invade the renal interstitium. Promoting factors are obstruction, reflux, urolithiasis, nephrolithiasis, pregnancy, diabetes mellitus, humoral and cellular immunodeficiencies, immunosuppression treatment (e.g. following transplants), autoimmune phenomena (antigenic mimicry). Therapy comprises the treatment of underlying disease, antibiotics as indicated by the resistogram, acidification of urine (L-methionine), i.v. immunoglobulins (IgM, IgG) and oral vaccination with lyophilized uropathogens.
