The role of diffusion-weighted MRI and contrast-enhanced MRI for differentiation between solid renal masses and renal cell carcinoma subtypes.

Purpose: To assess the value of diffusion-weighted magnetic resonance imaging (DW-MRI) and contrast-enhanced MRI (CE-MRI) for differentiation between benign and malignant solid renal masses, renal cell carcinoma (RCC) subtypes, oncocytomas, and lipid-poor angiomyolipomas (LP-AML).

Methods: Minimum or lowest 'apparent diffusion coefficient' (ADC) and representative ADC values (ADC) of 112 renal masses (n: 46 benign renal mass, n: 66 malignant renal mass) were measured on DW-MRI images (b 50, 400, 800 s/mm). Signal intensity (SI) measurements were performed in normal renal parenchyma and most avid enhanced area of the renal masses at precontrast, corticomedullary, and nephrographic phases on CE-MRI.

Multi-center evaluation of oxidation-reduction potential by the MiOXSYS in males with abnormal semen.

According to the World Health Organization (WHO), oxidative stress (OS) is a significant contributor to male infertility. Seminal OS can be measured by a number of assays, all of which are either costly or time sensitive and/or require large semen volume and complex instrumentation. One less expensive alternative is to quantify the oxidation-reduction potential (ORP) with the MiOXSYS.

Value of Shear Wave Elastography for differentiating benign and malignant renal lesions.

Aims: To investigate the diagnostic accuracy of shear-wave elastography (SWE) for assessing malignant and benign kidneymasses.

Materials And Methods: Forty patients with solid renal masses underwent US elastographic evaluation. SWE values of the lesions and adjacent cortical renal parenchyma and SWER were detected prospectively.

Roles of Signal Transducer Pathways in Investigation of Biopsies from Patients with Bladder Tumors.

Background:The process of development of bladder cancer features alteration of normal biological conditions caused by changes in molecular pathways. Removing control over regulation of these pathways could lead to changes in signal transduction and abnormal regulation of genes. During tumor formation and progression, genes regulate critical cellular processes, involved in cell cycling, growth and death.

The role of ultra-mini percutaneous nephrolithotomy in the treatment of kidney stones.

Objective: In our study we aimed to evaluate outcomes of ultra-mini-percutaneous nephrolithotomy (UMP) performed for the treatment of kidney stones.

Material And Methods: Between October 2014 and September 2015, a single surgeon performed UMP on a total of 49 consecutive patients with symptomatic kidney stones at our center. Pregnants, anticogulant users, patients with bleeding diathesis pyonephrosis, and partial/complete staghorn stones were excluded from the study.
