Abstract
Placement of internal ureteral stents for internal urinary diversion and prevention of urological complications has been well established. However, indwelling stents have occasionally been associated with patient morbidity and intolerance. A total of 255 patients while the internal ureteral stent had been used were analyzed. The symptoms including urinary frequency (42.0%), hematuria (41.6%) and suprapubic pain (20.4%), loin pain (17.3%) and micturition pain (16.9%) accounted for the major complaints of the stent indwelling patients. The major complications, i.e. stent migration, heavy encrustation, pyelonephritis, fragmentation, intolerance and penetration of collecting structure, were occasionally observed. These complications increase secondary morbidity in patients. The double-J stents should be used carefully with regard to the prevention and treatment of untoward conditions as early as possible.
