Percutaneous introduction of double-J ureteral stents.

Insertion of percutaneous indwelling ureteral stents was performed or attempted in 10 patients with ureteral obstruction or postoperative urinary extravasation. All patients had previously sustained an unsuccessful endoscopic retrograde attempt. The percutaneous double-J stent was inserted anatomically correctly in 8 (73%) cases and was functionally successful in 7 (64%). No significant complications occurred. As the percutaneous indwelling ureteral stent offers many advantages, i.e. little discomfort to the patient and none or insignificant complications, we want to advocate for the use of this method whenever the endoscopic technique fails.
