Feasibility of Magnetic-end Double-J Ureteral Stent Use in Children

Double-J ureteral stent (DJUS) is one of the most common devices used in urology. Ureteral stenting has a wide spectrum of indications that can be summarized in two words: obstruction and leakage. Common indications in pediatric urology are pyeloplasty, ureteral reimplantation, kidney transplantation and stone disease. Classically, DJUS are introduced and removed in the operation room, under general anesthesia, using a cystoscope. The magnetic-end Double-J ureteral stent is a 4.8 French DJUS with a small magnet fixed with a string at the distal loop. To remove the magnetic stent, a 9 French customized catheter-like retrieval device with a magnetic Tiemann tip is inserted into the urethra in the outpatient clinic. The purpose of this study is to demonstrate the feasibility and safety of magnetic-end Double-J ureteral stent use in children and to perform a medico-economic study.
