A newly created ureteral stenting catheter of double-ended pigtail design is introduced. The pigtail design at both ends maintains the catheter in place by serving as a solid anchoring device, both intravesically and within the renal pelvis; upward or downward migration of the stent is thus prevented. It is designed also to minimize trigonal irritation. The catheter can be introduced easily either cystoendoscopically or through a percutaneous antegrade route, or by a combination of both methods. It offers the additional advantage of being readily available from an inexpensive stock source; it may be quickly and easily custom made and shaped for any ureter by the physician immediately prior to its insertion. It thus avoids having to have premanufactured, more expensive ureteral stents of different lengths. Open surgery for upper urinary tract decompression can thus be avoided.
