Direct intraprostatic injection of ethiodol was done in 12 patients with benign prostatic hypertrophy to visualize lymphatic drainage of the prostate gland. In all 12 patients lymphatics of the prostate could be visualized well. The findings of our study indicate that the prostate mainly drains through 3 sets of lymphatics: 1) the main and important set of lymphatics starts from the superolateral angle of the prostate and courses along the lateral pelvic wall to drain into the internal iliac lymph nodes, 2) some lymphatics drain into the lymph nodes in the presacral area and 3) in 45% of the patients lymphatics from the apex of the prostate travel along the course of the internal pudendal vessels to the internal iliac lymph nodes. From the internal iliac lymph nodes the drainage is to the common iliac lymph nodes and, finally, to the lumbar lymph nodes. Each lateral lobe of the prostate drains mainly into the ipsilateral group of lymph nodes with little crossover of lymphatics to the opposite side. All patients tolerated the procedure well and there were no complication during or after the procedure. We believe that this procedure is a safe, simple and direct method to visualize lymphatic drainage of the human prostate gland.
对12例良性前列腺增生患者进行了前列腺内直接注射乙碘油，以观察前列腺的淋巴引流情况。在所有12例患者中，前列腺淋巴管均能清晰显示。我们的研究结果表明，前列腺主要通过3组淋巴管引流：1）主要且重要的一组淋巴管起自前列腺的上外侧角，沿盆腔侧壁走行，注入髂内淋巴结；2）一些淋巴管注入骶前区的淋巴结；3）45%的患者中，来自前列腺尖部的淋巴管沿阴部内血管走行至髂内淋巴结。从髂内淋巴结引流至髂总淋巴结，最终至腰淋巴结。前列腺的每个侧叶主要引流至同侧淋巴结组，淋巴管很少交叉至对侧。所有患者对该操作耐受性良好，操作过程中及操作后均无并发症。我们认为该操作是一种安全、简单且直接的观察人体前列腺淋巴引流的方法。
