The deposition of immune complexes is the causal factor in distinct renal pathologies, e.g., lupus nephritis and membranous nephritis. The location of these deposits within a tissue biopsy is often the key to establishing a diagnosis. However, how immune complexes come to be deposited below the vascular endothelium was, until now, a mystery, as was their contribution to inducing inflammation. A recent paper in Cell by Stamatiades et al. (Cell 164(4):991-1003, 2016) demonstrates the active transport of immune complexes by the vascular endothelial cells and an Fc receptor-dependent uptake by tissue-resident macrophages...

BACKGROUND: Renal cell carcinoma (RCC) represents the most common malignant epithelial neoplasm of the kidney. Accurate assessment of the renal masses, defining the histologic subtype and the grade of differentiation of the tumor, is vital to ensure an adequate case management as well as for staging and prognosis. Recently, diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) tends to be increasingly appealing for the clinicians as an imaging procedure of choice for the diagnosis and staging of the RCC, which is predetermined by several advantages over CT...

OBJECTIVES: To review the long-term outcomes of transecting versus non-transecting urethroplasty to repair bulbar urethral strictures. METHODS: A retrospective review was conducted of 342 patients who underwent anterior urethroplasty performed by a single surgeon from 2003 to 2014. Patients were excluded from further analysis if there had been prior urethroplasty, stricture location outside the bulbous urethra, or age <18 years. In the transecting group, surgical techniques used included excision and primary anastomosis and augmented anastomotic urethroplasty...

PURPOSE: Partial bladder outlet obstruction (PBOO) usually induces overactive bladder (OAB) associated with detrusor overactivity (DO) which is related to the increased contractility of detrusor smooth muscle (DSM). The pharmacological activation of small-conductance Ca(2+)-activated K(+) (SK) channels dramatically attenuates DSM contractility. However, the role of SK channels in the PBOO DSM is less clear. Here, we tested the hypothesis that PBOO is associated with decreased expression and function of SK channels in DSM and that the activation of SK channels is a potential target to regulate DO...

PURPOSE: The optimal vitamin D3 therapy for the treatment of secondary hyperparathyroidism (SHPT) in chronic hemodialysis patients is still controversial. Recent studies suggest that uremia in end-stage renal disease is associated with enzymatic hepatic dysfunction altering 25-hydroxylation of vitamin D3. The goal of our study was to compare the efficacy of calcitriol, the fully hydroxylated active form of vitamin D3, to alfacalcidol which needs 25-hydroxylation to be effective, for the treatment of SHPT in chronic hemodialysis patients...
