Laser resection of posterior urethral valves

Laser resection (LR) of posterior urethral valves during infancy as early as possible after diagnosis appears to represent a safe and reliable method. In contrast to other procedures, LR allows valve ablation with thin cystoscopes and carries little risk, even in premature and newborn infants. Its application in seven children in the course of 2 years principally confirmed its suitability for use: it could be applied in all cases without any problems and led to extensive resection of the valve tissue and removal of the obstruction in all patients. The encouraging clinical findings were confirmed by control cystoscopies and micturating cystourethrograms. Complications arising from the method were not observed.
