title: [Transpubic approach in radical prostatectomy].
abstract: Surgical interventions in prostate apex and urethral membranous part are difficult because these structures are in the depth of the small pelvis. Transpubic approach permits easy manipulations in this area. There are the following variants of this approach: symphysotomy, pubectomy, resection of superior horizontal rami of pubic bones, resection of inferior horizontal rami of pubic bones, clinoid resection of pubic bones. The simplicity, adequacy and convenience of different surgical manipulations are the advantages of transpubic approach. The clinoid resection of pubic bones is the optimal variant of this approach. In provides an adequate approach to operated organs, the integrity of pelvic ring is saved, as a result of which there are no severe orthopedic disorders in the nearest and remote postoperative periods. For determination of indications to transpubic approach, the comparative study of the transpubic and low-median approaches in radical prostatectomy was carried out in 50 male cadavers according to parameters proposed by Sozon-Yaroshevich in 1954. The type of constitution, height of symphysis, size and shape of the prostate puboprostatic ligaments, adhesion of ligaments to prostate, prostate position against symphysis, size of small pelvis venous vessels were taken into account. It was established that the angle of surgical action in wound in low-medium approach was 35-50 degrees, in transpubic approach--by 25-30 degrees more. Incline angle of surgical manipulation axis, which reflect the correspondence of surgical section to exposed organ's disposition, is very important in case of organ's immobile position. This angle in low-medium approach was 40 +/- 5 degrees, in transpubic--80-90 degrees. Dorsal venous plexus and urethrals membranous part are approachable if the prostate size is small, but if the prostate volume is more than 30 cm3 and symphysis is high (> 7 cm), it is very difficult to manipulate in this zone in low-medium approach. Transpubic approach warrants thorough and careful prostatectomy. Methods leading to disturbance of pelvic ring integrity (symphysotomy, pubectomy) have no advantages. Clinoid resection ensures the optimum view of operative field and satisfy the main requirements of surgical approach.
