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 usage of 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.3 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.
