MR imaging of idiopathic trigeminal neuralgia: correlation with non-surgical therapy

Urinary drainage by indwelling double J ureteral stent is well documented in the urologic literature. We used these stents in 91 patients. The majority of stents were placed endoscopically (68%). Indications were: -Ureteral obstruction (39 cases) such as tuberculous ureteral strictures, obstruction due to urolithiasis and pelvic malignancies. -Upper urinary tract surgery (29 cases) mainly pyeloplasty, pyelolithotomy, ureterovaginal fistula repair and ureteroneocystostomy. -Adjunct to endourologic treatment (16 cases) such as ureteroscopy and endopyelotomy. -Preparation for extracorporeal lithotripsy (7 cases). The complication rate associated with placement of double J stents was minimal (6.6%). The major complication was migration (3 cases). The average drainage time was 5.8 weeks. In view of these results we conclude that double J stent is safe, effective and has minimal complications.
