Renal Stone Disease in a Swedish District During One Year

Abstract

In a Swedish district served by only one hospital the annual incidence of urinary stone colic was estimated to 1.4 per 1000 inhabitants. Sixty-two per cent of the patients were treated entirely as out patients whereas 9% required some form of surgery during the study. Thirty-seven per cent of the patients were recurrent stone formers. No significant seasonal variation in stone incidence was noted. A definite reason for stone formation could be established in 6%, and among 56 patients with recurrent stone disease run through a biochemical investigation, abnormal findings were recorded in 70%.
