Percutaneous transvesical antegrade ablation of posterior urethral valves.
A technique of ablation of posterior urethral valves in a neonate is described. It involves two useful modifications of antegrade suprapubic approach. These modifications include the use of a matured percutaneous suprapubic tract for antegrade fulguration of valves and the utilization of a small urethral catheter as a guide for the valve ablation. The urethral catheter also protects the urethra from fulguration injury.
