Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (renal calculus) develops in the urinary tract. [2] Renal calculi typically form in the kidney and leave the body in the urine stream. [2] A small calculus may pass without causing symptoms. [2]
This means an anteroposterior diameter of less than 4 mm in fetuses up to 32 weeks of gestational age and 7 mm afterwards. [18] In adults, cutoff values for renal pelvic dilation have been defined differently by different sources, with anteroposterior diameters ranging between 10 and 20 mm. [ 19 ] About 13% of normal healthy adults have a ...
[2] [3] [4] The table below is intended to assist people working with the alternative calculus called the "geometric calculus" (or its discrete analog). Interested readers are encouraged to improve the table by inserting citations for verification, and by inserting more functions and more calculi.

Kidney showing circumscribed calcium deposits together with a partial stag horn calculus. Nephrocalcinosis , once known as Albright's calcinosis after Fuller Albright , is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism .
[4] Cherwell-Wright differential equation: 1 = (()) or the related form ′ = () An example of a nonlinear delay differential equation; applications in number theory, distribution of primes, and control theory [5] [6] [7]
To compute the integral, we set n to its value and use the reduction formula to express it in terms of the (n – 1) or (n – 2) integral. The lower index integral can be used to calculate the higher index ones; the process is continued repeatedly until we reach a point where the function to be integrated can be computed, usually when its index is 0 or 1.
These include differential equations, manifolds, Lie groups, and ergodic theory. [4] This article gives a summary of the most important of these. This article lists equations from Newtonian mechanics , see analytical mechanics for the more general formulation of classical mechanics (which includes Lagrangian and Hamiltonian mechanics ).
