Adjunctive medical therapy with α-blocker after extracorporeal shock wave lithotripsy of renal and ureteral stones: a meta-analysis. [PDF]

open access: yesPLoS ONE, 2015
Although some trials assessed the efficacy and safety of the α-blocker in facilitating renal and ureteral stones expulsion after extracorporeal shock wave lithotripsy (ESWL), the role of the α-blocker in facilitating upper urinary calculi expulsion after

Percutaneous Management of Urinary Calculi [PDF]

open access: yesThe Scientific World JOURNAL, 2004
The revolution of minimally invasive surgery began in 1976 when Fernstrom and Johannson performed the first percutaneous nephrolithotomy (PNL). Urologists then began to realize the potential of renal surgery through small percutaneous tracts, and have refined the procedure into what is routinely practiced throughout the world today.

In vitro analysis of urinary stone composition in dual-energy computed tomography [PDF]

open access: yes, 2018
Purpose: Dual energy computed tomography (DECT) is a new method of computed tomography (CT) imaging, allowing the assessment of not only the object's morphology, but also its composition.

Linear Depth Deduction with Subformula Property for Intuitionistic Epistemic Logic [PDF]

open access: yesarXiv, 2021
In their seminal paper Artemov and Protopopescu provide Hilbert formal systems, Brower-Heyting-Kolmogorov and Kripke semantics for the logics of intuitionistic belief and knowledge. Subsequently Krupski has proved that the logic of intuitionistic knowledge is PSPACE-complete and Su and Sano have provided calculi enjoying the subformula property.

BRCA2 mutations in familial breast cancer with prostate cancer: a case report and literature review

open access: yesFrontiers in Oncology
Prostate cancer (PCa) is the second most common tumor in men globally. Its etiology has been attributed to multiple factors, including age and ethnicity, with family history identified as a significant risk factor.

Regular Calculi I: Graphical Regular Logic [PDF]

open access: yesarXiv, 2021
What is ergonomic syntax for relations? In this first paper in a series of two, to answer the question we define regular calculi: a suitably structured functor from a category representing the syntax of regular logic to the category of posets, that takes each object to the poset of relations on that type.

New methods for the treatment of renal calculi : the St. Luke’s Hospital experience [PDF]

open access: yes, 1989
The last decade has seen extraordinary advances in the management of urinary tract calculi. With the introduction of minimally invasive techniques, like percutaneus nephrolithotomy (PCN), and non-invasive ones, like extra-corporeal shock wave lithotripsy

Effect of retention time on renal function and kidney size in patients with indwelling DJ tubes

open access: yesScientific Reports
The impact of DJ tube retention time on renal function has received scant attention from researchers. Nevertheless, there is a plethora of clinical evidence indicating that protracted stent retention can result in renal insufficiency, or even renal ...

Projective real calculi over matrix algebras [PDF]

open access: yesarXiv, 2021
In analogy with the geometric situation, we study real calculi over projective modules and show that they can be realized as projections of free real calculi. Moreover, we consider real calculi over matrix algebras and discuss several aspects of the classification problem for real calculi in this case, leading to the concept of quasi-equivalence of ...
