We present 2 cases of urethral duplication in girls, which has rarely been reported. Neither patient had any associated abnormalities. After a review of their clinical treatment and the current data on female urethral duplication, we recommend excision of the duplicated urethra and encourage diligent investigation in girls with complete incontinence, perineal discharge, or perineal or suprapubic sinuses, because urethral duplication might be underdiagnosed. A thorough examination is required, because most cases of duplication can be identified with careful inspection.
