The authors describe an original technique of postoperative drainage of percutaneous nephrolithotomy consisting of leaving a 5 F ureteric catheter in place, which descends into the bladder and drains into a conventional 18 or 20 F nephrostomy drain. It ensures ureteric drainage while eliminating the need for a urethral catheter, protects the nephrostomy tunnel by maintaining the nephrostomy drain in place and maintains access to the caliceal group used for percutaneous nephrolithotomy.
