Reconstruction of the autonomic nerve controlling urogenital tract and its clinical application

研究结果如下：1)犬盆腔神经重建：(1)采用端对端高频吻合重建盆腔神经。(2)盆腔神经缺损处的生殖股神经移植或结肠神经移植术均能高频修复通路。(3)保留神经功能的犬膀胱自体移植成功。(4)犬盆腔神经移植到新膀胱成功。将腹下神经移植于盆腔神经和支配结肠作为新膀胱的结肠神经之间。手术后，盆腔神经的刺激引起了所有5只狗的新膀胱收缩。(2)犬腹下神经的重建：(1)证实了犬腹下神经在长时间横断一半长度后可以自发重建。(2)颏股神经移植或结肠神经移植对胃下神经缺损的通路修复频率较高。III)在显微镜或电镜下观察到移植物轴突的再生。4)临床上，用于射精的腰椎植神经重建和用于勃起的海绵体神经重建均取得成功。

The research results are as follows.I) Reconstruction of the canine pelvic nerve :(1) The pelvic nerve was reconstructed by end-to-end anastomosis in high frequency.(2) Either genitofemoral nerve grafting or colonic nerve frafting in the defect of the pelvic nerve repaired the pathway in high frequency.(3) Auto-transplantation of the canine bladder preserving nerve function succeeded.(4) Redistribution of the canine pelvic nerve to the neobladder succeeded. The hypogastric nerve was grafted between the pelvic nerve and colonic nerve which innervate the colon used as neobladder. After this operation, stimulation of the pelvic nerve elicited contraction of the neobladder in all 5 dogs examined.II) Reconstruction of the canine hypogastric nerve :(1) Spontaneous reconstruction of the canine hypogastric nerve after transection of its half length over a long period was demonstrated.(2) Either genistofemoral nerve grafting or colonic nerve grafting in the defect of the hypogastric nerve repaired the pathway in high frequency.III) Regeneration of the axon in the nerve graft was identified on microscopy or electron microscopy.IV) Clinically, both reconstruction of the lumbar splanchnic nerve for ejaculation and that of the corpus spongiosum nerve for erection were successful.
