Microvascularisation of the male urethra in neonates and infants.
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.
