[Analgesic nephropathy].
Analgesic nephropathy is a slowly progressive disease caused by the chronic abuse of analgesic mixtures containing two analgesic components combined with potentially addictive substances (coffeine and/or codeine). Pathologically, the nephropathy is characterized by renal papillary necrosis with calcification and chronic interstitial nephritis sometimes in association with transitional-cell carcinoma of the uroepithelium. In the early stage, the clinical characteristics are polyuria, sterile pyuria, sometimes renal colic and haematuria. With further progression of the disease, there are the nonspecific symptoms of advanced renal failure. The incidence of classic analgesic nephropathy among Hungarian patients on chronic renal replacement therapy has proven. There is an urgent need for the estimation of analgesic nephropathy among patients with chronic renal disease and among patients with chronic pain presumably regularly taking analgesics in Hungary. As long as analgesic mixtures containing phenacetin or paracetamol and/or nonsteroidal antiinflammatory drugs and addictive substances are available "over-the-counter", analgesic nephropathy will continue to be a problem also in our country.
