Double J stents. A review of 100 patients.

Double J stents have been advocated for drainage or splintage of the ureter. One hundred and thirty-eight attempts at stent insertion were made in 100 patients. In 78% of attempts the stent was satisfactorily placed. Their use in retroperitoneal fibrosis, ureteric trauma and acute hydronephrosis of pregnancy has been encouraging. Poor results have been obtained in patients with malignant obstruction or tuberculous stricture.
