The authors report a rare malformation : a minor form of epispadias responsible for urinary stress incontinence. This incontinence was present during childhood, disappeared during adolescence and recurred following several pregnancies. The diagnosis was made on the basis of separation of the labia minora combined with apparent absence of the clitoris. The authors report a perfect result with a two year follow-up, obtained by V-Y plasty of the bladder neck associated with aponeurotic suspension using the technique of Gobbel-Stoeckel. The risk of increasing existing reflux led to the performance at the same time of a bilateral anti-reflux operation by advancement. This case is of interest by virtue of its rarity.
