neourethra
Neourethra refers to a surgically constructed urethral channel created to replace or augment the native urethra. It is used in several clinical contexts, most commonly in repair of hypospadias, where the urethral opening is not at the tip of the penis, and in gender-affirming phalloplasty, where a functional urethra is needed to urinate from a neophallus. It may also be employed after traumatic injury, congenital absence of the urethra, or severe urethral stricture.
Construction of a neourethra involves tissue grafts or flaps that form a tube-like channel. Common tissue sources
Outcomes vary with technique and patient factors. Potential complications include urethrocutaneous fistula (an abnormal connection to
