The use of Alken Metal Telescopic Dilator for 'X-ray-free' PCNL in neglected DJ stent patient: A case report.

Neglected DJ stent is a challenging case, due to the procedures required, using fluoroscopy, as seen in ESWL, URS, and PCNL. This study presents the case of a 54 years old woman with pyelum and ureter stones, alongside neglected DJ stent for about a year. Treatment was started with cystoscopy, URS lithotripsy, which was continued with kidney puncture, and the subsequent dilatation with Alken Metal Telescopic Dilator. All steps were performed under the guidance of ultrasonography without fluoroscopy. The result showed a successful removal of DJ stent, which was achieved percutaneously, and no remaining stone was found.
