Results
The data of 476 patients whose information was obtained and who
underwent RRP were evaluated. The demographic data and basal PSA values
of the first group with four-focus VUA and the second group with
six-focus VUA were similar. The majority of the patients in both groups
consisted of patients with Gleason score 3 + 3 and 3 + 4. Prostate
volume and perioperative data were also similar between the two groups.
There was no significant difference between the T stage of the
prostatectomy specimens. Comparison of the demographic and perioperative
data of the groups is summarized in Table 1 .
The proportion of patients with VUA stricture in the first group was
significantly higher than in the second group (5.1% vs 3.2%, p =
0.017). Also, the mean time to stricture development was shorter in the
first group (48.9 vs 74.3 days, p = 0.002). Although the continence
rates in the sixth month decreased in both groups compared to the
preoperative condition, the continence rate in the second group was
higher than the first group (79.3% vs 62.8%, p <0.001). At
12 months, improvement in continence status was observed in both groups,
but the second group had a higher rate of continence again (92.4% vs
81.3%, p = 0.032). Continence restoration curves for the two groups are
shown in Figure 3 . The proportions of potent patients in the
two groups tended to decrease at 6 months, but improvement was seen at
12 months. In addition, there was no significant difference between the
two groups in terms of potent patient rates (p = 0.194 for the 6th month
and p = 0.351 for the 12th month). The restoration curves comparing the
potency rates of the two groups are schematized in Figure 4 .
The comparison of the functional results of the two groups at 6 and 12
months is summarized in Table 2 .
