[Treatment of macroscopic hematuria complicating renal biopsy by embolization of a branch of the renal artery].

The authors describe a case of recurrent macroscopic haematuria which developed after renal biopsy in a young patient with IgA dominant focal and segmental mesangioproliferative glomerulonephritis. As conservative treatment was not successful, renal angiography was performed which revealed a false aneurysm of the segmental branch of the renal artery at the site of the assumed puncture. After selective embolization with gelaspon granules macroscopic haematuria receded quickly.
