Simple method of residual stone retrieval through the nephrostomy catheter after PCNL: point of technique.
A simple technique of removal of residual stone fragments in patients who have undergone percutaneous nephrolithotripsy (PCNL) and have a nephrostomy tube in situ is described. Under local anesthesia and sedation a rigid 8.5 F ureteroscope is passed through the nephrostomy tube and the stones retrieved. This technique is indicated in patients who have 1-3 residual fragments, none larger than 5 mm, and located in the same calyx or pelvis as the tip of the nephrostomy tube.
