Abstract

Background: The second ("safety") of two guide wires is commonly inserted antegradely in percutaneous nephrolithotripsy (PCNL). We describe the retrograde insertion of a through-and-through safety guide wire during PCNL. Methods: After inserting a percutaneous nephrostomy 1 day earlier, a guide wire was introduced through the nephrostomy tube to the bladder and pulled out through the urethral meatus via a cystoscope and grasper. The tube was removed, leaving the wire positioned from the flank to the meatus. A dual-lumen catheter was introduced retrogradely through the urethra over the wire, up to the nephrostomy incision. The safety guide wire was introduced retrogradely through the catheter's other port. Results: This procedure succeeded in 9 of 10 patients: the exception was very obese and the catheter was too short to reach the incision in the flank. Conclusion: Using a dual-lumen catheter allows quick and simple retrograde insertion of a safety guide wire during PCNL.
