[Early and late results after cryosurgical treatment of bladder neck obstructions (author's transl)].
We report on late results of 100 risk patients, who were operated by cryosurgical technique because of bladder neck obstructions. Detailed representation of complications. The primary mortality was 5%. Controls after one year showed good functional results on 80% of the patients. 60% of the patients had sterile urine, whereas only 17% of the male patients had no infection before the operation. As to the anatomical results we could talk of a cryoprostatectomy in 25% of the cases. Because of a 20% failure cryosurgery remains a palliative operation, which can only be carried out on risk patients. Because of little hemorrhagic diathesis and the possibility to perform this operation under local anesthesia cryosurgical operations on the other hand are suitable for patients, who cannot be anesthetised. Otherwise these patients had needed a permanent catheter. We prefer shorter freezing times of 3--4 min. Essentially we could show the same functional results as other authors, who preferred longer freezing times, until they reached a certain temperature in the prostatic capsule. By shorter freezing times on the contrary we could avoid secondary transurethral resections of larger necroses. New disturbed micturition after cryosurgical treatment of the prostate is unusual. The question of a later recidivation is of secondary importance because of the primary high morbidity rate of the selected number of cases.
