Conductive Reduced Graphene Oxide-Silk Fibroin Bionanocomposites.

This research paper describes the fabrication of bionanocomposites (BNCs) based on silk fibroin (SF) and reduced graphene oxide (rGO). The recorded UV-visible (UV-vis) spectra of the sample confirm the reduction of GO to rGO in SF by showing a plasmon resonance band within the wavelength range of 261-268 nm. The X-ray diffraction (XRD) peak at 11.

Likelihood of Distal Ureteric Calculi to Pass Spontaneously: Systematic Review and Cumulative Analysis of the Placebo Arm of Randomized-Controlled Trials.

Introduction: Distal ureteric calculi remain a widely debated topic without clear consensus on expectant management. This systematic review aims to assess the placebo arms of RCTs to extrapolate data on the natural history of distal ureteral stones and ascertain the success rate of expectant management.

Methods: A literature search was performed, and 3 reviewers used a predefined inclusion criterion to independently select articles for inclusion.

Validation of radius exophytic/endophytic nearness anterior/posterior location and preoperative aspects and dimensions used for an anatomical nephrometric scores in patients undergoing partial nephrectomy for renal cancer: A single-center experience and literature review.

Introduction: Nephrometric scores are used to predict perioperative and postoperative complications, with no uniform results in the current literature.

Materials And Methods: A retrospective study of 141 patients in a single center who underwent open partial nephrectomy between June 2006 and 2016 for T1a and T1b renal tumor was conducted. Univariate and multivariate analyses were used to evaluate the correlations between preoperative aspects and dimensions used for an anatomical (PADUA) and radius exophytic/endophytic nearness anterior/posterior location (RENAL) scores and their components with pre-, peri-, and post-operative parameters.

Percutaneous extraction of appendicolith an extension of endourology corridor.

Percutaneous procedure represents a novel, easy, and safe removal of retained appendicolith. This gives an advantage of less invasive treatment, shorter hospital stay, and enhanced recovery of the patients.

The natural history of asymptomatic calyceal stones.

Objectives: To evaluate the outcomes of patients with incidentally detected asymptomatic calyceal stones on active surveillance, and to identify risk factors for stone-related adverse events (AEs).

Patients And Methods: In this retrospective case series, we identified all renal units with non-contrast computed tomography diagnosed asymptomatic calyceal stones in a single reference centre between August 2005 and August 2016. Primary endpoints were spontaneous stone passage and need for stone-related surgical intervention.
