title: Freezing index in cryosurgery on the prostate gland.
abstract: Cryosurgery has been performed on 18 patients with prostatic hypertrophy, and the following conclusions are reached: The quotient obtained by dividing the estimated weight of the prostate gland by the frozen weight obtained by an equation is called the freezing index, and this index can be introduced into the evaluation of the results of cryosurgery on the prostate gland. Cryosurgery was not markedly effective in cases of freezing indices over 0.76, and the incidence of complications was high in cases of freezing indices not more than 0.5. The ideal freezing index obtained empirically was 0.6. No dysuria has recurred during past three years in the cases where cryosurgery was assessed satisfactory in effect within two to three months.
