Therapeutic embolization of polycystic kidneys.

In two patients with end-stage polycystic kidneys suffering from severe and protracted hematuria recourse was made to therapeutic renal embolization. Hematuria stopped immediately, never to appear again, whilst recanalization of the arterial renal circulation was observed later. Since the therapeutic embolization of kidneys in patients with end-stage uremia is exceedingly risky and, therefore, unadvised, it is regarded only in the case of a bleeding polycystic kidney as implementable and more effective than nephrectomy.
