To investigate the clinical effect of percutaneous nephrolithotomy (PCNL) combined with ureteroscopy in the treatment of calculi caused by long-term indwelling double J tubes.

From July 2010 to May 2020, seven patients in our hospital with double J tube stones at both ends and body part were admitted. Six patients were treated with tranurethral ureteroscopic lithotripsy at lithotomy position to clear the stones in the inner bladder, the intersegment and the lower segment of the ureteral wall. One patient underwent soft cystoscopy to remove the stones in the inner wall of the output canal. The patient was changed to the prone position, and the percutaneous nephrolithotomy channel was established under the guidance of X-ray or ultrasound. After the calculi were sufficiently removed, the catheter was removed anterograde.

There were 7 patients, 2 patients with severe hydronephrosis received renal puncture and nephrostomy preoperatively, and 5 patients completed treatment in the first stage. All seven patients completed the treatment, and completely without serious complications. During 3-12 months of follow-up, no ureteral stenosis occurred.

Percutaneous nephrolithotomy combined with ureteroscopy is a safe and effective surgical method for treating severe double J tubular calculi caused by long-term catheter retention, which can completely remove the calculi, safely remove the catheter, and reduce the incidence of postoperative ureteral stricture.
