Abstract:
We report the case of a female (chromosomal 46 XX) with a complex congenital urogenital malformation. Caesarian section was performed at the 30th gestational week due to hydrops fetalis and polyhydramnion. Clinical and radiological evaluation demonstrated a complex urogenital malformation with an enlarged penoclitoral organ, urethral duplication, and concomitant malformations. The girl presented with a female urethra with a vaginal orificium as well as a male urethra culminating in a microphallus. Additionally, a urethral valve formation just cranial to the bifurcation of the male and female urethra was also present. Due to concomitant diseases, a complicated clinical course and recurrent urinary tract infections, the final operative correction resulting in a female phenotype, was performed at the age of 2 (1/2) years as a single-stage procedure.

The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
