Procedure was cystoscopy with left retrograde pyelogram, attempted left ureteral stent.Fluoroscopy showed the wire and the stent coiled in the renal pelvis.The wire was started to be removed; however, it caused crumpling of the stent, and under fluoroscopy as the wire was being removed, the stent appeared to be bending and pleating over the wire, but was not disengaging from the wire.Several attempts were made to pull the wire out of the stent, and it would not disengage.Ultimately, the wire and stent were removed en bloc through the penis.Because the wire appeared to have been embedded and engaged halfway through the stent, the stent was cut.Another attempt was made to thread a wire through this stent using a hydrophilic wire, but unfortunately, the tip of the remaining stent was in the bladder and had already disengaged the ureteral orifice.The cystoscope was then replaced.It was clear that the process of removing the stent had caused considerable swelling and edema around the left ureteral orifice which was also bleeding.The pt was admitted to observation and for placement of a percutaneous nephrostomy tube.Fda safety report id(s)# (b)(4).
