Urinary Tract Fistulas: Transrenal Reversible Ureteral Occlusion With Detachable Semicompliant Balloons.

Objective: To evaluate transrenal reversible ureteral occlusion with detachable balloons in patients with treatment-refractory urinary tract fistulas.

Methods: From September 2009 to September 2013, reversible occlusion of 18 ureters (7 men, 3 women; 27-74 years) with treatment-refractory urinary leakage mostly because of tumor disease or iatrogenic surgical injury was performed. Nephrostomy was exchanged fluoroscopically into an 8F or 9F sheath, which was introduced into the ureter to the point of intended balloon inflation.

Energy and metabolic sensing G protein-coupled receptors during lactation-induced changes in energy balance.

The free fatty acid receptor FFA1, FFA2, and FFA3 and hydroxy-carboxylic acid receptor (HCA2) are G protein-coupled receptors, acting as energy and metabolic sensors. Herein, we characterized the tissue-specific mRNA abundance of genes encoding for these receptors at different stages of lactation. In addition, potential effects of supplementation with or without conjugated linoleic acids (CLA) were tested.

Longitudinal profiling of the tissue-specific expression of genes related with insulin sensitivity in dairy cows during lactation focusing on different fat depots.

In dairy cows the milk associated energy output in early lactation exceeds the input via voluntary feed intake. To spare glucose for mammary lactose synthesis, peripheral insulin sensitivity (IS) is reduced and fat mobilization is stimulated. For these processes a link between IS and the endocrine functions of adipose tissue (AT) is likely; we thus aimed to characterise the mRNA expression from bovine AT derived proteins and receptors that are related to IS according to the literature in metabolically active tissues plus systemic IS throughout lactation.

Two thermoformable spiral metallic ureteral stents in a patient with ileal conduit and distal stenosis of the ureters.

The insertion of two thermoformable ureteral titanium spiral stents (Memokath® 051) through ileal conduit due to bilateral ureteral stenosis distally has not been described in the English literature so far. We present the case of a young female patient with a history of ileal conduit urinary diversion due to congenital urinary bladder exstrophy, who had multiple previous surgeries and the insertion of two Memokath® ureteral stents in both ureters due to distal ureteral stenosis.
