    Abstract:
    Between August, 1986 and February, 1988, double J ureteral catheters were placed in 441 renal units of 419 patients (22 were bilateral) with complex renal stones prior to ESWL. Catheter placement was achieved in all but 3.8% of the cases using several techniques, mainly via the retrograde route. Placement of the double J catheter was indicated in almost 75% of cases with a large stone mass (staghorn or pseudo staghorn). Only 11% of post-ESWL "Steinstrasse" were obstructive; of these, 80% resolved spontaneously. The complication rate was 21%. Most of these cases were mild complications. All cases were resolved satisfactorily. We believe that the double J catheter is useful in patients with complex renal stones. Placement of a double J catheter involves a simple maneuver with a low morbidity. It aids ESWL, reduces complications, and avoids more important endourologic maneuvers.
