[Spontaneous regression of a dolichomegaureter in a 4-month-old child]

The authors report a relatively rare case of dolichomegaureter followed up over a period of almost 8 years and which regressed spontaneously and almost completely. They envisage the various pathogenic hypotheses. The interest of this particular case lies on the one hand in the photographic documentation and secondly because of the regression of the dolichomegaureter slowly over the years, long after the disappearance of urinary infection and all treatment had been stopped. This course tended to confirm that the hypothesis of infectious megaureter due to a reversible acute inflammatory obstruction is not the sole explanation for the regression of certain large ureters in the infant.
