ABSTRACT
The microvascularisation of the male urethra was studied in neonates and infants by injection of agarised China ink into the circulation. The purpose of this study was to specify the angioarchitecture of each tunic of the urethral wall. The disposition of the microvascularisation networks varies depending on the urethral parts considered: only the mucous membrane networks are uniform throughout the entire urethra. The sub-mucous networks are significantly increased in the spongy part. The muscular networks disappear in the spongy part.

The microvascularization of the female urethra was studied in fetuses, neonates and infants by injection of agarized China ink into the circulation. The purpose of this study was to specify the angioarchitecture of each tunic and their specific drainage. The disposition of the microvascularization of the urethra is superimposed on the orientation of the fibers of the muscular tunic. The orientation of the veins of the sub-mucous tunic is longitudinal and not plexiform.
