Abstract
Introduction: Ureteroscopy-assisted retrograde nephrostomy (UARN) makes it is possible to continuously visualize dilation of the ureter from the site of puncture to insertion of the nephroaccess sheath, with minimal complications and effective for percutaneous nephrolithotripsy (PCNL).
Case Report: A 43-year-old male with cerebrotendinous xanthomatosis (CTX) was referred to our department to undergo PCNL for a diagnosis of a right kidney stone. In July 2012, the patient was admitted to our department for PCNL to treat a right renal staghorn calculus. We performed PCNL using the technique of UARN. The operative time was 195 minutes, and the chemical composition of the stone was calcium oxalate.
Conclusion: UARN is effective for the case who have large renal stone with complications of CTX.
