men had negative lateral/posterior margins. For the
17 patients, perioperative data showed a fluid loss (blood
and urine) of 300 ml (interquartile range [IQR]: 200–400),
and perioperative complications were grades 1–2
( Table 2).

Postoperative clinical outcomes
Table 2shows the clinical, biochemical, and pathologic
outcomes. Median nadir PSA value was 0.4 ng/ml (0.3–0.7),
representing a reduction of 8.7 ng/ml (94%; 95% confi-
dence interval (CI), 7.3–10.2) compared with baseline PSA.
Median time to achieve PSA nadir was 3 mo.
Figure 3shows PSA variations from the nadir value. PSA outcomes
were not suspicious for cancer during follow-up in 13 of
17 patients (76%). Of these, three patients had a PSA rise
with a velocity
<
0.10 ng/ml per year (cases 4, 5, and 7) and
doubling time of 6.1 yr (case 5)
( Fig. 3a); mpMRI showed
residual BPH at the prostate base as the most likely cause
