prevalence of urinary Calculus during pregnancy and its rate of relapse are similar to non-pregnant women. Averagely, its prevalence in pregnant women is 1 per 1500 of pregnant women. Urinary Calculus in pregnant women may be cause about 40% of delivery before term in pregnancies with marked urinary Calculus. Urinary Calculus's signs in pregnant women are similar to non-pregnant women and is one of the main causes of abdominal acute pains. It may be possible to mistake with pregnancy's signs so it is required to study more from diagnosis point, because the delay on diagnosis and find treatment may risk the result of pregnancy and lead kidny's damage. It is difficult to treat urinary Calculus during pregnancy and require a cooperation between Gynecologist, Urologist and radiologist. In the first stage, urinary Calculus treatment is non-surgery and conservative and urologic intervention should be done when the pharmaceutical and non-surgery Therapy are not effective. However, there is a great change in urinary Calculus's treatment by PCN and ESWL, techniques, but usage of these techniques in pregnant women should be examed by cases and then applied. It must be avoided from any kind of invasive operation and limit it to emergency cases. Urinary Calculus can be removed in every stage of pregnancy with surgery. Habitual abortion with a surgical operation may occur more in the last 3 months of pregnancy.

In this paper, we study fuzzy Calculus in two main branches differential and integral. Some rules for finding limit and gH -derivative of gH -difference, constant multiple of two fuzzy-valued functions are obtained and we also present fuzzy chain rule for calculating gH -derivative of a composite function. Two techniques namely, Leibniz’s rule and integration by parts are introduced for fuzzy integrals. Furthermore, we prove three essential theorems such as a fuzzy intermediate value theorem, fuzzy mean value theorem for integral and mean value theorem for gH -derivative. We derive a Bolzano’s theorem, Rolle’s theorem and some properties for gH -differentiable functions. To illustrate and explain these rules and theorems, we have provided several examples in details.

Let $I\subseteq\mathbb{R}$ be an interval and $\beta\colon I\to I$ a strictly increasing continuous function with a unique fixed point $s_0\in I$ satisfying $(t-s_0)(\beta(t)-t)\le 0$ for all $t\in I$. Hamza et al. introduced the general quantum difference operator $D_{\beta}$ by $D_{\beta}f(t):=\frac{f(\beta(t))-f(t)}{\beta(t)-t}$ if $t\ne s_0$ and $D_{\beta}f(t):=f'(s_0)$ if $t=s_0$.   In this paper, we establish results concerning Taylor's formula associated with $D_{\beta}$. For this, we define two types of monomials and then present our main results. The obtained results are new in the literature and are useful for further research in the field.
