[Cryoprostatectomy of prostatic tumors].
Since 1968, we have carried out cryoprostatectomy on prostatic hypertrophy and prostatic cancer patients. As for the method of monitoring during cryoprostatectomy, digital examination only was carried out at the beginning in order to confirm the range of freezing and to determine the freezing time. In 1972, we developed a cryoprostatectomy method under direct intravesicular observation using the Trocar Cystoscope and furthermore in 1980, we developed echoguided cryoprostatectomy using the transrectal linear electronic scanner. These new developments ensure the safety of cryoprostatectomy and furthermore, cryoprostatectomy can now be easily carried out. The above-mentioned procedures are described.
