A method for treating benign prostate hyperplasia is provided. The method is effected by (a) inserting a cystoscope into a prostatic urethra portion of a urethra of a patient having benign prostate hyperplasia; (b) guiding a probe of a cryoprobe having an operating tip through a channel of the cystoscope to an portion of the prostatic urethra; (c) navigating the operating tip through a wall of the prostatic urethra into at least one location at a time of a prostate of the patient; and (d) operating the cryoprobe thereby cooling the operating tip and producing an ice-ball of prostate tissue around the operating tip, so as to locally freeze a portion of the prostate, yet substantially avoid freezing the prostatic urethra.
