Case report: infected solitary renal cyst.

The case of a patient with a solitary infected renal cyst is described. Although solitary renal cysts appear frequently, it seems that they rarely become infected, as is demonstrated by the fact that from a search of the world literature up to 1978l, only 21 such cases were described. With the current techniques such as arteriography, CT scanning and echography, diagnosis represents no problem. As far as therapy is concerned, it would seem that resection of the cyst wall and drainage is to be preferred over nephrectomy.
