Patient selection and data collection
Five hundred thirty-five patients who underwent RRP between June 2015
and June 2019 were evaluated. Patients who had a history of pelvic
radiotherapy, urethral intervention, overactive bladder and / or
neurogenous bladder and who used drugs that could affect continence were
excluded from the study. The remaining 476 patients were included in the
study. Patients were divided into two groups according to the VUA
technique: patients who underwent four focal VUA (12-, 3-, 6-, and
9-o’clock positions) (group I) and patients who underwent six focal VUA
(12-, 2-, 4-, 6-, 8- and 10-o’clock positions) (group II). There were
288 patients in group I and 188 patients in group II. The flow chart of
the study is shown in Figure 1 . All data were collected
retrospectively from the hospital database. Demographic, perioperative
and postoperative data and functional results of the two groups were
recorded and analyzed.
