A rare complication of ureteral double-J stenting after flexible ureteroscopy: Renal parenchymal perforation

Abstract

Double-j (DJ) ureteral stenting is a very common procedure performed after various endourological procedures. Although several complications due to DJ stent insertion were revealed, only three cases of renal parenchymal perforation have been reported to date. We present a case of a 35-year-old woman who had perforation of renal parenchyma without perirenal hematoma following insertion of DJ ureteral stent after flexible ureteroscopy for the treatment of an upper ureteral calculi. Non-contrast computed tomography was used for diagnosis. Patient was successfully managed with repositioning of the stent under fluoroscopic guidance on postoperative second day postoperatively.
