Thirty consecutive anesthesia records of transurethral resection (TUR) have been reviewed. Patient's physical status, anesthetic management and complications were also discussed. Operations in this series were classified as follows: 25 cases of TUR for carcinoma of the prostate, 3 cases of bladder tumor. In all the thirty cases of TUR, circulatory diseases, such as hypertension were encountered most frequently. (10 cases) The patients had the highest mean age(66.5 years old) and their physical status was almost all ASA class II or III. Hypotension occurred in 1 patient during TURP. There was no death associated with anesthesia and operation in this study. Pain control after operation with epidural block was satisfactory in nearly all cases. Continuous epidural anesthesia for TUR and pain control after operation was desirable.
