[Cryosurgical treatment of prostate gland cancer]

The authors share their experience with cryosurgical treatment of 38 patients with prostatic cancer (stage T3--in 9 patients, T4--in 29). The technic of cryotherapy is described. The former was employed in patients with complete obstruction of the cervico-urethral segment being nonresponsive to the hormone- and radiotherapy, and also for a life cystostome. Three freezing sessions for 5--15 minutes were conducted with natural warming of the prostate between sessions during 10--12 minutes, and forced warming for 3--4 minutes after the third session. The optimum time of cryoeffect was 5--7 minutes. The postoperative period was smooth, uncomplicated. The process of rejection of the frozen tissues lasted for up to 4--6 weeks, after that a suprapubic drainage was withdrawn and uresis was restored. 32 patients were discharged from the clinic, the survival up to 3 months--in 2, up to 6 months--in 6, up to 1 year--in 4, up to 2 years--in 7, up to 3 years--in 7.
