在32侧成人标本上解剖观察了前列腺的动脉和神经的起源和分布。供应前列腺的动脉主要为膀胱下动脉的分支,平均每侧有5.6支(2～6)。其分出点于膀胱前列腺间沟的4(8)及3(9)点钟之上24±10mm((?)±SD),各支可经膀胱前列腺间沟的任何一处进入前列腺实质或其包膜。至海绵体组织的植物性神经主要集中于膀胱前列腺间沟及前列腺表面的4点和8点钟外。作者认为,于膀胱前列腺连接部的侧面盲目缝扎包膜,试图结扎其中的动脉而达止血的目的,未必奏效。我们在7例良性前列腺增生的手术摘除术中,采用直视下膀胱下动脉结扎的方法,结扎动脉干可靠,术中术后出血量显著减少。因不会误扎神经,可避免术后病人性功障碍。
Anatomical observations of the origin and distribution of the arteries and nerves of the prostate were performed on 32 adult specimens. The main artery supplying the prostate is the branch of the inferior vesical artery with an average of 5.6 (2-6) on each side. The points of separation in the bladder between the prostate gland on the 4 (8) and 3 (9) 24 ± 10mm (± SD) above, each branch of the prostate through the gland of the prostate gut anywhere into the prostate parenchyma or Its envelope. The vegetative nerve to the cavernous tissue mainly concentrates outside of the bladder gland and prostate surface at 4 o’clock and 8 o’clock. The author believes that the side of the bladder prostatic junction blind suture capsule, trying to ligation of which arteries to reach the goal of bleeding, may not be effective. We in 7 cases of benign prostatic hyperplasia surgical excision, under direct vision of the method of ligation of the inferior artery, ligation of the artery is reliable, postoperative bleeding was significantly reduced. Because they will not accidentally tie the nerves, postoperative patients can avoid sexual dysfunction.
