Measurement of residual adenoma after transurethral resection of the prostate by transurethral enucleation technique.
OBJECTIVE
Transurethral resection of the prostate (TURP) leaves a lot of residual adenoma and has a high recurrence rate, but the residual adenoma weight has not been measured surgically. Using surgery we tried to measure the residual adenoma after TURP.


METHODS
Total adenoma resection was performed via standard TURP in 64 cases with benign prostatic hyperplasia and the weight of the residual adenoma was measured by transurethral enucleation (TUE) of the prostate.


RESULTS
Prostate volume averaged 37.4 ml and adenoma volume averaged 20.6 ml by TRUS. The average weight of the prostate removed by TURP was 9.8 g. After TURP residual adenoma was confirmed in all cases by TUE, and the average weight of the residual adenoma was 10.2 g. The total average prostate volume removed by TURP and TUE was 20.1 g. The average residual rate of the adenoma removed by TURP was 54.5%.


CONCLUSIONS
TURP leaves about half of the adenoma. Therefore, TURP might be very difficult for complete resection of an adenoma.
