输尿管上2/3的结石,根据结石所在平面,采取适当的腹膜后入路,可以直接取出。输尿管下1/3的结石,通过腹膜后途径不容易接近。在男性,狭窄的骨盆漏斗,以及附近的结构像大血管,使得解剖困难。通常,满意的暴露既困难,又需要广泛的肌肉切开,而且有广泛的组织挛缩。由于这些原因,输尿管下1/3的结石,已有经腹取除的报道。这种方法,克服了手术野深,并且由于输尿管周围慢性炎症造成的困难。但是,有尿液漏入 Ureteral 2/3 of the stones, according to the plane where the stones, to take appropriate retroperitoneal approach, you can directly remove. Ureteral stone under 1/3, through the retroperitoneal approach is not easy to access. In men, the narrow pelvic funnel, as well as the nearby structures like large blood vessels, make anatomy difficult. In general, satisfactory exposure is both difficult and requires extensive muscle dissection and extensive tissue contracture. For these reasons, one third of the stones in the ureter have been reported by abdominal ablation. This method overcomes the problem of deep surgical field and difficulties due to chronic inflammation around the ureter. However, there is leakage of urine
