[Data analysis of the objective observation parameters of benign prostatic hyperplasia patients accepting different treatment regimens].
OBJECTIVE
To observe different objective observation parameters of the benign prostatic hyperplasia (BPH) patients accepting different treatment strategies, and to further analyze the relationship of these factors with the treatment option.


METHODS
Three hundred and twenty-nine BPH patients, aged 50-80, were assigned into 3 groups jointly decided by the physicians and patients based on the individual conditions and the patients' willingness: watchful waiting group (n=61), aged (63 +/- 8), drug treatment group (n=179), aged (68 +/- 7), and operation group (n=89), aged (71 +/- 6). The data of prostate volume, prostate specific antigen (PSA), maximum flow rate (Qmax), average flow rate, urinating volume, and residual urine volume before treatment were recorded.


RESULTS
The prostate volume of the watchful waiting group was 33.0 ml, significantly smaller then those of the drug treatment and operation groups (40.1 and 65.5 ml respectively, both P < 0.01); the Qmax of the watchful waiting group was 17.1 ml/s, significantly higher than those of the drug treatment and operation groups (12.4 and 9.1 ml/s respectively, both P < 0.01), and the urinating volume of the watchful waiting group was 332 ml, significantly more than those of the drug treatment and operation groups (247 and 188 ml respectively, both P < 0.01). The serum PSA of the operation group was 5.44 ng/ml, significantly higher than those of the watchful waiting and drug treatment groups (1.53 and 1.99 ng/ml respectively, both P < 0.01); and the residual urine volume of the operation group was 208 ml, significantly higher than those of the watchful waiting and drug treatment groups (21 and 45 ml respectively, both P < 0.01). There were no significant differences in the serum PSA and residual urine volume between the drug treatment and watchful waiting groups.


CONCLUSIONS
Prostate volume, PSA, Qmax, average flow rate, urinating volume, and residual urine volume are important influential factors influencing the treatment option of BPH. Data analysis of the objective observation parameters will be helpful in clinical decision making.
