Ureteral Stent Fragmentation： a Case Report and Review of Literature

SINCE the introduction of double J stents in 1978, ureteral stents have become an integral tool in treating ureteral obstruction from calculi and other causes.1 Owing to the widespread usageof indwelling ureteral catheters, a number of possible complications such as migration, infection, pyelonephritis, breakage, encrustation, stone formation, and ureteral stents fragmentation have been noted.2 Of all the complications, ureteral stent fragmentation was sporadically reported and believed to be rare. Here we present a case of fragmentation of a new type of double J stent, which was used to provide free drainage to the bladder after balloon dilation.
