Popis: Ureteral stenting has become one of the most common endoscopic procedure in endourology. Its main purpose is to preserve urinary drainage if this is compromised and maintain a good renal function. Even if there were made significant improvements in the last 50 years, ureteral stenting is not without morbidity. The common ureteral stents cannot have a good long-term efficiency and at some points, it will be blocked by the encrustation and incrustation; as result, the urinary drainage will have to suffer. A total of 134 ureteral stents in 83 patients suffering from reno/ureteral lithiasis were examined. We investigated the risk factors of encrustation and analyzed the chemical compounds of it. A total of 57 stents were found encrusted. The main risk factor was represented by the indwelling time. The rate of encrustation was 18.33% in the first 5 weeks, 56% between week 6 and 12, 75% thereafter. Stents with a smaller caliber (4.8 CH) tend to be more encrusted than those with a bigger one (6 CH). The Fourier Transform Infrared Spectroscopy has found that the main chemical compound of encrustation is represented by calcium oxalate.
