INTRODUCTION This study aimed to ascertain whether nonopacified kidney on excretory urography (also known as intravenous urography [IVU]) indicates nonsalvageability. METHODS We retrospectively reviewed 45 adult patients with chronic unilateral urinary tract obstruction, in whom IVU revealed nonopacified kidney on one side but normal excretion on the contralateral side. Affected kidneys with ...

renal masses can be categorized as benign and malignant lesions. among the renal malignancies, renal cell carcinoma is the most common malignancy. however, other rare malignant lesions should be considered in differential diagnosis. primary renal lymphoma is quite rare and might be mistaken for renal cell carcinoma. due to lack of lymphatic tissue in the kidney, pathogenesis of renal lymphoma i...

purpose post exercise proteinuria and increased urinary gamma-glutamyl transferase (ggt) levels can be indicative of exercise-induced renal damage. the aim of this investigation is to study the effect of one session of intensive training on renal damage markers and compare their values to those 6 hours after training. methods in this cross-sectional study with pre- and post-test design, 10 elit...

we investigate a class of fourth-order differential operators with eigenparameter dependent boundary conditions and transmission conditions. a self-adjoint linear operator a is defined in a suitable hilbert space h such that the eigenvalues of such a problem coincide with those of a . we discuss asymptotic behavior of its eigenvalues and completeness of its eigenfunctions. finally, we obtain th...

in this paper, a numerical solution for a system of linear fredholm integro-differential equations by means of the sinc method is considered. this approximation reduces the system of integro-differential equations to an explicit system of algebraic equations. the exponential convergence rate $o(e^{-k sqrt{n}})$ of the method is proved. the analytical results are illustrated with numerical examp...

in this paper, we consider non-linear ginsburg-pitaevski-gross equation with the rosen-morse and modifiedwoods-saxon potentials which is corresponding to the quantum vortices and has important applications in turbulence theory. we use the runge- kutta-fehlberg approximation method to solve the resulting non-linear equation.

in the present paper, we prove subordination, superordination and sandwich-type properties of a certain integral operators for univalent functions on open unit disc, moreover the special behavior of this class is investigated.
