An 81-year-old male patient was admitted to hospital because of macrohematuria. The clinical examination revealed a multifractured double J stent which had been placed 17 months before in another clinic because of hydronephrosis. In the reported case, a combined endoscopic and open surgical management was necessary to remove all fragments from the renal pelvis, the ureter and the bladder. Occlusion, encrustration and migration are among the most frequent risks of ureter stenting. The breakage of the stent, however, is a rare but severe complication. Therefore, patients should generally be controlled by sonography every 2 months and when malfunction of the stent is suspected, a cystogram should follow. In general, a stent exchange should be performed after 12 months.
