'Sting' procedure in the treatment of secondary reflux in children.

The authors present their experience (24 children) with the endoscopic subureteral injection of Teflon paste in the correction of secondary vesicoureteral reflux: reimplantation failure; ureterocele; obstructive bladder; exstrophy; postchemocystitis, and Hutch's diverticulum. Of these 24 cases (31 refluxing ureters), 18 were treated with success. Each cause justifies a comment on the particularities of its endoscopic treatment. The 'sting' can be particularly attractive to cure secondary reflux, avoiding the difficulties and complications of open surgical reimplantation.
