Transurethral prostatic resection (TUR) is now established as an alternative to open surgery. The indicative criteria of TUR, however, has not yet clearly defined, because the selection of the operative methods for BPH is influenced by surgeon's preference.
During the 8-year period between January, 1976 and December, 1983, 159 patients operated upon for BPH were reviewed by comparing the results of 125 TUR on 121 cases (T. group) and 38 open surgery (O. group) as to hematuria period, catheter drainage period, admission period and complication after operation.
Furthermore T group was evaluated regarding catheter drainage, pyuria, azotemia and anemia before operation, patient age, operation time and weight of resected specimen using the same criteria as above.
The results were as follows:
1) T. group as superior to O. group in several respects, that is 2.1 days of hematuria period vs. 5.7 days, 4.3 days of catheter drainage period vs. 10.7 days, 15.4 days on admission period vs. 25.5 days and 28% of complication after operation vs. 31.6%.
2) There existed a positive correlation between operation time and weight of resected specimen in T. group, but not in O. group. In the former group 0.23g were resected per minute, while in the latter 0.31g However, when limited cases with resected specimen below 40g were compared, T. group was superior to O. group by 0.23 vs. 0.20g/min.
3) Evaluation of T. group suggested that preoperative catheter drainage, preoperative pyuria and older age above 80 tended to affect adversely.
4) In TUR, operation time and weight of resected specimen paralleled the age of patient, and as operation time prolonged and weight of resected specimen increased, operative result was prone to be affected adversely.
In conclusion, it is suggested that early operation for symptomatic BPH with the gland clinically estimated less than 50g, control of preoperative pyuria, and limit of resection time within 120 minutes were important factors for stable TUR.
