Conclusions: Transureteroscopic holmium laser lithotripsy is an effective and safe method for ureteral calculi. 结论经输尿管镜钬激光碎石是一种有效、全的腔内碎石方法。
Additional diagnostic tests may be necessary to distinguish FIC from other diseases that cause lower urinary tract symptoms in cats such as bacterial urinary tract infection( rare in young to middle-aged cats), stones( also called ca 为了辨别FIC和其他下泌尿道疾病,如细菌性下泌尿道感染(少发生在年轻到中年的猫)结石(叫做结石或尿石)和肿瘤(发生于猫)附加的诊断性检验也许是必须的。
Calculi \Cal"cu*li\, n. pl. See {Calculus}.
Calculus \Cal"cu*lus\, n.; pl. {Calculi}. [L, calculus. See {Calculate}, and {Calcule}.] 1. (Med.) Any solid concretion, formed in any part of the body, but most frequent in the organs that act as reservoirs, and in the passages connected with them; as, biliary calculi; urinary calculi, etc.
2. (Math.) A method of computation; any process of reasoning by the use of symbols; any branch of mathematics that may involve calculation.
{Barycentric calculus}, a method of treating geometry by defining a point as the center of gravity of certain other points to which co["e]fficients or weights are ascribed.
{Calculus of functions}, that branch of mathematics which treats of the forms of functions that shall satisfy given conditions.
{Calculus of operations}, that branch of mathematical logic that treats of all operations that satisfy given conditions.
{Calculus of probabilities}, the science that treats of the computation of the probabilities of events, or the application of numbers to chance.
{Calculus of variations}, a branch of mathematics in which the laws of dependence which bind the variable quantities together are themselves subject to change.
{Differential calculus}, a method of investigating mathematical questions by using the ratio of certain indefinitely small quantities called differentials. The problems are primarily of this form: to find how the change in some variable quantity alters at each instant the value of a quantity dependent upon it.
{Exponential calculus}, that part of algebra which treats of exponents.
{Imaginary calculus}, a method of investigating the relations of real or imaginary quantities by the use of the imaginary symbols and quantities of algebra.
{Integral calculus}, a method which in the reverse of the differential, the primary object of which is to learn from the known ratio of the indefinitely small changes of two or more magnitudes, the relation of the magnitudes themselves, or, in other words, from having the differential of an algebraic expression to find the expression itself.
