[Clinical and histological studies on the course of glomerulonephritis]

It is reported on 37 patients in whom on the basis of the clinical suspicion of a glomerulonephritis a biopsy of the kidneys was carried out, and after treatment in these patients a rebiopsy was carried out 21 months later in order to examine clinical and histological changes during this period. Hereby could be established that the rebiopsy only six times evoked an apparant improvement, whereas the other cases showed clinical findings or deterioration and only in half the cases a correspondence between clinical and histological developmental tendencies was recognizable. As conclusion indications to rebiopsy are proposed.
