尿流转向,在泌尿系疾病上占着极其重要的地位,不论暂时性的或永久性的尿流转向,很少有一面既不影响病人的生理状态而又便于病人排尿的良好方法.自simon氏第一次施行永久性乙状结肠输尿管吻合术后,许多学者相继应用这种手术,在早期虽有很高的死亡率和一些并发症,但仍不失为一个较为理想的手术,因而在国外施行该手术者较为普遍,在国内沈绍基、吴皆平两氏1955年首先报告16例,陈家騼,方开先,熊汝成三氏1958年报告43例,都有一定效果,其他医院虽未见报导,但此种手术已日益普遍.输尿管乙状结肠吻合术的主要目的,是为了在膀胱或尿道的先天性畸形,创伤或疾病造成的正常贮尿或尿流发生障碍,通过肛门扩约肌的控制得到排尿作用.在临床上这种手术仍有很多缺点,Smith及Hinman氏在1955年经动物实验和临床观察,认为返流、高氯性酸中毒及肾盂肾炎,是输尿管乙状结肠吻合后常见的件发症,因为输尿管移植在结肠后,受到粪 Urinary flow steering, plays an extremely important role in urological diseases, regardless of temporary or permanent urinary flow, few have a good way to both affect the patient’s physiological condition and facilitate the patient’s urination.Since simon ’S first application of permanent sigmoid ureter anastomosis, many scholars have used this operation in succession, although in the early stage of high mortality and some complications, but still a satisfactory surgery, so the implementation of the operation abroad More common in the domestic Shen Shaoji, Wu Jieping two first reported 16 cases in 1955, Chen Jiali, Fang Kai first, Xiong Rucheng San’s report in 1958 43 cases, have some effect, although no other hospital reported, but such surgery has become increasingly common . The main purpose of ureteral sigmoid anastomosis is to prevent the normal storage of urine or urinary flow in the bladder or urethral congenital malformations, trauma or disease, and obtain the urinary function through the control of the anal sphincter .In clinically this There are still many shortcomings of surgery, Smith and Hinman in 1955 by animal experiments and clinical observations, that reflux, high chloride acidosis and pyelonephritis, ureter B Common colon-like complications after anastomosis, because the ureter transplant in the colon, by the feces
