[Change of nerve growth factor mRNA in human detrusor in bladder outlet obstruction with benign prostatic hyperplasia and their implication].

OBJECTIVE

To investigate the change of nerve growth factor (NGF) mRNA in human detrusor in bladder outlet obstruction (BOO) with benign prostatic hyperplasia (BPH) and their implication.

METHODS

Eight cases of bladder cancer and 40 patients with BPH were included in this study. All patients were divided into three groups, a control group, an obstructive detrusor stability group and an obstructive detrusor instability group. NGF mRNA in detrusor from all patients was measured using a RT-PCR.

RESULTS

The RT-PCR study indicated that NGF mRNA was expressed in detrusor of three groups of patients. There were significant differences among the three groups (P < 0.01). The expression of NGF mRNA in the obstructive instability group was higher than that in the obstructive stability group and in the control group. The NGF mRNA level in the obstructive stability group was higher than that in the control group.

CONCLUSION

The expression of NGF mRNA in detrusor was elevated in BOO with BPH. The elevated expression of NGF mRNA might be correlated with detrusor instability (DI) due to BOO.
