title: [Spontaneous perirenal extravasation of urine].
abstract: Perirenal urinary extravasation in the course of violent renal colic appears to occur much more frequently than is reported in the literature. In this study, the authors report on three such cases observed personally in the space of one year and discuss the pathophysiological factors which may give rise to this phenomenon.
