title: [Cryoprostatectomy--practice and problems].
abstract: We reviewed 479 cases of cryoprostatectomy, 361 of which were performed using the 1-or 2-stage refreezing method, and 118 cases which were done by freezing only once. The refreezing methods gave better clinical and radiographic results as compared with the once-freezing method. As complications were seen in 20% of the cases in which the refreezing method was used and 10% of those in which the once-freezing method was used. Sonographic control was useful for the prevention of complications.
