Prophylactic double J (DJ) stent insertion has been adopted as a routine procedure in renal transplant patients for internal urinary diversion and for protecting ureteroneocystostomy anastomosis. The timely and early removal of stent has been proved to reduce the occurrence of stent-associated complications such as migration, encrustation, and infection. The most commonly used procedure of sten...

Urease has attracted much attention, as it is directly involved in the formation of infection stones and contributes to the pathogenesis of urolithiasis, pyelonephritis, ammonia and hepatic encephalopathy, hepatic coma and urinary catheter encrustation. Moreover, urease is the major cause of pathologies induced by H. pylori, such as gastritis and peptic ulcer. In the present work, the new natur...

The effect of fluence level on the discoloration of marble surfaces after the removal of the encrustation by 355 nm laser pulses is comparatively studied. Considering the thermochemical reaction possibly occurring in the encrustation during laser irradiation, the mechanism responsible for the discoloration of the cleaned marble surface is analyzed. The reduction of iron oxides by graphite plays...

Urinary catheters often become encrusted and blocked by crystalline Proteus mirabilis biofilms. Results of experiments in a laboratory model of a Foley catheterised bladder infected with P mirabilis showed that when retention balloons were inflated with a solution of triclosan (10 g/L), the catheters drained freely for at least 7 days. Triclosan became impregnated throughout the silicone cathet...

We have characterized the types of encrustations that form on ureteral stents. The deposit generates blocks is composed hydroxyapatite/magnesium ammonium phosphate (44%). Calcium oxalate dihydrate was also detected at a high degree encrustation (13%). Hydroxyapatite deposits, (13%) are generated due to their formation as consequence persistently urinary pH values. large uric acid deposits (31%)...
