PURPOSE - To prospectively evaluate 5α-reductase inhibitors (5αRIs) for benign prostatic hyperplasia (BPH) patients with a large prostate (>80 mL) after transurethral resection of the prostate (TURP).
METHODS - Eighty-seven patients were recruited from January 2007 to October 2014. Patients were randomized into a trial and a control group. The trial group was treated with 5αRIs for 3 years after TURP, while the control group received a placebo. We evaluated the indicators before, peri and after TURP.
RESULTS - There were no significant differences in the indicators before and peri-TURP. Six months later, there were significant differences in PSA and hematuria (HU). Three years after TURP, there were significant differences in prostate volume (PV), level of prostate-specific antigen (PSA), the maximum flow rate (Qm), and HU between the trial and control groups. Additionally, there were significant differences in the PV, PSA, international prostate symptom score (IPSS), patient quality of life (QoL) in the trial group alone between those treated with finasteride and those treated with dutasteride.
CONCLUSIONS - After TURP for large BPH, administration of 5αRIs for 3 years improved PV, PSA, Qm and HU. Additionally, dutasteride produced superior improvements in PV, PSA, IPSS and QoL compared with finasteride.
