The intrinsic nerve plexus of the human ureter. A histochemical study of dilated and normal ureters with particular reference to children with meningomyeloceles.

SUMMARY 
A study of the intramural nerve supply of the dilated ureters of children with meningomyeloceles shows a definite plexus surrounding each muscle bundle with isolated nerve cells scattered in between. These were seen at all levels. No difference is seen in the structure of the intrinsic supply in dilated ureters from that in normal controls. It is postulated that the abnormality of ureteric function is related to variable potentiation of the intramural neuromuscular plexus by the extrinsic supply.
