Abstract:
TURP is one of the common operations in the urologic field, and it has been well shown as a golden standard treatment modality for the patients with the BPH. Nevertheless, there was no available objective index to determine effective amount of the prostate resection. Therefore, we reviewed and evaluated the charts of 119 BPH patients more than 15 in modified Boyarsky symptom score evaluation, and who have undergone TURP from 1992 to June 1994. In addition, we excluded the cases associated with the other disease, such as neurogenic bladder, urethral stricture, or prostatic carcinoma. The volume of prostate was calculated by using of TRUS and ellipsoid formula. The maximal flow rate(MFR) was evaluated mostly on 5th post-operative volume of the day. We defined the resection rate(R.R) as the rate of the resected weight to the volume of the prostate. The results were as follows. 1. The mean resection rate of the prostate was 42.1%. 2. The average of the post-operative MFR was 20.52ml/sec. 3. The relevance between the RR and the post-operative MFR was not shown herein. 4. Distribution of the patients by the postoperative modified Boyarsky symptom score was different according to the resection rate. Statistically significant difference of the postoperative modified Boyarsky symptom score was shown between the greater than 30% resection group 1ess than 30% resection group(P=<0.05) 5. The post-operative modified Boyarsky symptom score could be predicted by the equation induced through the regression analysis. Symptom score = 5.28 - (0.04'RR) Our results suggest that resection rate of 30% is the marginal rate for the desirable voiding improvement, and, if it is practicable, the resection of more than 30% is favorable for all patients with BPH.
