[Prevention of catheter dislodgment: modified nephrostomy with pigtail and balloon].
Insertion of a percutaneous nephrostomy for decompression of the collecting system in cases of obstruction should be easy and safe to perform. Early or delayed catheter dislodgment is a more frequent event. Even with optimal positioning of the puncture site, this complication cannot be prevented reliably. Should dislodgment occur, a new puncture is necessary in most cases exposing the patient to risk and discomfort. The modified percutaneous nephrostomy tube presented here was designed for better protection against dislodgment while retaining technical ease of tube insertion.
