On IVU, the signs indicating radiolucent ureteral calculus were as follows: full-length opacification of unilateral ureter with mild dilatation, abrupt narrowing of a segment of the ureter, break of opacification of a short segment of the ureter, thickened interureteric ridge, abrupt separating sign, obstructive nephrogram, filling defect and calculous staining.

Abstract］ objective to summarize the methods and experience and analysing of curative effects of open operation combined eswl treating renal staghorn calculi.methods therapeutic results of 8 cases of renal staghorn calculi were analysed retrospectively.results the lithous horn of 8 cases were broken by eswl before operation,then the renal calculus were removed by pyelolithotomy or extended pyelolithotomy.conclusion the method was a good choice of renal staghorn calculi with high stone-free rate,little trauma and less complication.

摘要］ 目的总结开放性手术结合eswl治疗鹿角状肾脏结石方法经验并进行疗效分析。方法回顾分析了8例鹿角状肾脏结石患者的治疗结果。结果 8例患者术前eswl将结石角粉碎，然后应用肾盂切开或肾窦扩大切开手术取出肾盂和肾盏内结石。结论该方法对于鹿角状肾脏结石治疗，结石取净率高，对肾脏损伤小、并发症少，是较为适合的方法。

It is well known that the Cartan form is nonunique for higher-order Lagrangian density, we find it was caused by higher-order mixed multiple integral in using Stokes formula in actually calculus variation.

众所周知，高阶Lagrangian对应的Cartan形式是不唯一的，在实际的变分计算中，我们发现Cartan形式的不唯一性是由利用Stokes公式求高阶混合多重积分的不唯一性引起的。
