Ensnaring the upward migration of double-J stent through nephrostomy route using a wire lasso.

Insertion of double-J (DJ) stent is common in pediatric urology practice as an internal urinary diversion. The DJ stent may migrate proximally into the renal pelvis which is a rare complication. We used a wire lasso to ensnare DJ stent ste through the nephrostomy route using a rigid cystoscope to retrieve the upward migration of DJ stent in 7 years old boy with right vesico-ureteric junction obstruction that previously had a re-implantation of the right ureter. As a result, the DJ stent were safely retrieved with slightly hematuria that improved before 24 hours.
