Mean±SD of baseline IIEF-15 score, EHS,
IPSS and OABSS were 26.0±20.4, 2.2±1.5, 7.9±6.1 and 3.3±2.7 in Tad group and 21.0±17.9,
1.9±1.6, 7.7±5.9 and 3.4±2.2 in Tam group respectively, with no significant
difference. Mean±SD of IIEF-15 and EHS 1,3,6,12 months after PB were 17.0±14.1,
23.3±18,8, 23.6±18.9, 25.3±21.6 and 1.9±1.6, 2.3±1.4, 2.2±1.5, 2.3±1.4 in Tad
group, and 14.7±10.9, 15.7±13.2, 17.2±12.6, 19.2±14.0 and 1.3±1.5, 1.4±1.4,
1.4±1.3, 1.6±1.3 in Tam group. IIEF-15 score were significantly decreased in
both groups at a month. after PB compared with the baseline (Tam group: p=0.001
Tad group: p<0.001). It was improved to a level not significantly different
from the baseline (baseline level) at 3 months in the Tad group and at 6 months
in the Tam group. EHS was significantly decreased at the 1, 3, 6 months after PB
compared with the baseline (p=0.013, p=0.039, p=0.002, respectively) and it was
improved to baseline level at 12 months, in the Tam group.
In contrast, it was not significant difference between baseline and 1, 3, 6, 12
months after PB in Tad group. Comparing of two groups, IIEF-15 score was
significantly lower in Tam group than in Tad group at 3 months only (p=0.011).
On the other hand, EHS was significantly lower in the Tam group than in Tad
group at 1, 3, 6, 12 months (p=0.046, p=0.002, p=0.007, p=0.019, respectively).
Mean±SD of IPSS and OABSS 1, 3, 6, 12 months after PB were 17.4±9.2, 17.0±8.8, 14.9±8.9
and 9.6±6.8 6.6±3.9, 7.1±3.6, 5.8±3.4, 4.1±2.6 in Tad group, and 16.1±8.5, 15.6±8.2,
13.0±7.2, 9.1±6.6 and 6.0±3.3, 6.0±3.1, 5.1±2.7, 3.7±2.4 in Tam group. They were
significantly higher in both groups at the 1, 3, 6 months
after PB compared with the baseline (Tad group: IPSS; all p<0.001, OABSS;
all p<0.001, Tam group: IPSS; p=0.001, p<0.001, p<0.001, OABSS; all p<0.001,
respectively). They were improved to baseline level only in Tam group at 12 months.
There were no significant differences between two groups at the 1, 3, 6,12 months.
