BACKGROUND AND PURPOSE The study compared characteristics and outcomes in patients with solitary and bilateral kidneys who were treated with percutaneous nephrolithotomy (PCNL) in the Clinical Research Office of the Endourological Society (CROES) PCNL Global Study. PATIENTS AND METHODS Data from consecutively treated patients from 96 centers worldwide were collated after a 1-year period. The ...

In this paper, the solitary waves in coupled nonlinear Schrodinger equations are classified into infinite families. For each of the first three families, the parameter region is specified and the parameter dependence of its solitary waves described and explained. We found that the parameter regions of these solution families are novel and irregular, and the parameter dependence of the solitary ...

We study the solitary waves and their interaction for a six-order generalized Boussinesq equation (SGBE) both numerically and analytically. A shooting method with appropriate initial conditions, based on the phase plane analysis around the equilibrium point, is used to construct the solitary-wave solutions for this nonintegrable equation. A symmetric three-level implicit finite difference schem...

solitary plasmocytoma is rarely located in the cranial vault. we report one case of solitary plasmacytoma of the skull and discuss the clinical features and treatment of this uncommon tumor in the light of the published cases. a 46-year-old moroccan male, without previous history consulted for a swelling in medial frontal and paramedian region. on clinical examination the clinical examination r...

The effect of weak lateral dispersion of Zakharov-Kutznetsov-type on a Benjamin-Ono solitary wave is studied both asymptotically and numerically. The asymptotic solution is based on an approximate variational solution for the solitary wave, which is then modulated in time through the use of conservation equations. The effect of the dispersive radiation shed as the solitary wave evolves is also ...

Solitary axillary schwannomas are very rare lesions, with just over 20 cases previously reported in the literature. Here we describe a patient symptomatic solitary schwannoma

  Abstract   A solitary plasmacytoma of bone occurs in approximately 2-5% of patients with   myeloma. The lesion mostly found in the axial skeleton and have infrequently been   reported to arise in the hand, and usually occur in the distal phalanges. We report the   interesting case of a 75-year-old man who developed a solitary lytic lesion of the   thumb proximal phalanx. This lesion was explo...

Eosinophilic granuloma is benign end of the spectrum of the Langerhans cell histiocytosis (LCH) which is characterized by solitary or multiple lesions in bones, skin, lung, lymph node etc. Here, we present a case of a 13-year old boy with pain and swelling in the right parietal region of skull with no other complaint. A computerized tomography (CT) scan and subsequent fine needle aspiration cyt...

In this paper we study several aspects of solitary wave solutions of the Ostrovsky equation. Using variational methods, we show that as the rotation parameter goes to zero, ground state solitary waves of the Ostrovsky equation converge to solitary waves of the Korteweg-deVries equation. We also investigate the properties of the function d(c) which determines the stability of the ground states. ...

patients with solitary rectal ulcer syndrome (srus) come to a physician with passage of mucus and bloody liquid within defecation. the treatment for srus is depended to the severity of symptoms and the existance of rectal prolapse. this study is a report of the assessing of rectopexy as surgical modalities for 62 medical treatment resistant srus patients who were referred to the gastrointestina...
