[Preoperative diagnosis of renal hamartoma]

The authors have diagnosed, preoperatively, for the second time a hamartoma renis in a 39-year-old patient. Enucleation of a solitary hamartoma renis in which the kidney could be saved has never appeared in literature until now. The authors are of the opinion that with the aid of arteriography but specifically by means of ultrasound the chances of a correct preoperative diagnosis are at least doubled.
