INTRODUCTION There is debate on renal graft stenting during ureteroneocystostomy, patients with ureteral stents may encounter several complications such as encrustation, stent crustation which can lead to loss of kidney, and complications related to stent extraction: pain and UTI increasing related to cystoscopy for stent extraction accompanying excess expenses. This study designed to reduce co...

Materials currently used for bladder applications often suffer from incomplete coverage by urothelial cells (cells that line the interior of the bladder and ureter) which leads to the continuous exposure of the underlying materials aggravating an immune response. In particular, a ureteral (or sometimes called an ureteric or bladder) stent is a thin tube inserted into the ureter to prevent or tr...

Background and objectives This controlled single-blind trial compared the efficacy of a lip balm with propolis special extract GH 2002 at a concentration of 0.5% in the treatment of episodes of herpes labialis with that of 5% aciclovir cream. Methods Patients in the erythematous/papular stage were randomized: 189 patients were treated with propolis cream, 190 patients were treated with aciclo...

Urinary catheters are commonly placed in ED patients to manage urine output, provide bladder drainage, and facilitate the care of patients with unstable hemodynamics. Many of these patients are admitted to the hospital for treatment, and the catheter may remain in place for days or during the entire time of hospitalization. There are risks associated with the use of urinary catheters. They can ...

Young standard dark mink developed classical symptoms of biotin deficiency, including underfur-greying, "spectacle eye," loss of fur, exudates from eyes, nose and mouth and encrustation of paws, when fed a diet containing 10% commercially produced, denatured spray-dried eggs. Comparable animals fed 5% spray-dried eggs did not show these symptoms; however, their pelts tended to be browner (i.e.,...

The fungus Beauveria caledonica was highly tolerant to toxic metals and solubilized cadmium, copper, lead, and zinc minerals, converting them into oxalates. This fungus was found to overexcrete organic acids with strong metal-chelating properties (oxalic and citric acids), suggesting that a ligand-promoted mechanism was the main mechanism of mineral dissolution. Our data also suggested that oxa...

OBJECTIVES To assess the role of temporary thermally expandable urethral stents in maintaining urethral patency in patients with a recurrent bulbar urethral stricture. PATIENTS AND METHODS Twenty-three men with a recurrent bulbar urethral stricture after several attempts at direct visual internal urethrotomy (DVIU) and/or failed urethroplasty were managed with a thermally expandable, biocompa...

Abstract Introduction Ureteric stents are routinely used in ureteric obstruction, however, have considerable morbidity with major complications, such as encrustation, urosepsis, and renal failure if left situ for longer than six months. Despite an electronic stent register, there still multiple emergency admissions of complications from forgotten stents, well those presenting significant sympto...

Supersaturation occurs in many industrial applications promoting reactive crystallisation between the reactants to form solutes. These solutes accumulate during precipitation, leading formation of scales on inner walls reactor and particularly around stirrer, causing modifications hydrodynamics. This encrustation is responsible for process shutdowns continuous processes. control essential proce...
