Incidence of analgesic nephropathy among patients undergoing renal replacement therapy in Czech republic and Slovak republic
Abstrakt
Background. The occurrence of analgesic nephropathy (AN) among renal replacement therapy patients in former Czechoslovakia is not known.
Previous surveys were not based on representative samples and lacked uniform criteria for diagnosing the disease. Methods.
Incidence of AN in former Czechoslovakia was investigated in patients commencing renal replacement therapy in 24 (1/3 of all) dialysis centres from 1 January to 31 December 1992. Patients showing an unclear renal diagnosis (n = 149) were investigated with an interview and renal imaging techniques.
The diagnosis of AN was withheld or rejected on the base of recently published diagnostic criteria demonstrating that a decreased renal mass of both kidneys combined with bumpy contours and/or papillary calcifications had a high performance for diagnosing AN
