Abstract

Congenital urethral stricture are uncommon in boys and occurs at the junction of the endodermal primary urethra and ectodermal secondary urethra. This structure is thought to be related embryonically to failure of complete dissolution of urogenital membrane at the junction of the urogenital sinus and genital fold. Endoscopically, this lesion is recognized as a ring-form stenosis just distal to the external urethral sphincter. Congenital urethral stricture is an important cause of recurrent urinary tract infections, enuresis, failure in thrive or hematuria in pediatric urological practice. The most effective treatment of this lesion is optic internal urethrotomy under direct vision. We report two cases of 6 and 12-year-old boys hospitalized with complaints of high fever, dysuria, urgency and frequency. Six-year-old boy has grade III VUR and 12-year-old boy has grade IV VUR with Hutch diverticulum. We managed with visual internal urethrotomy only in 6-year-old boy but visual internal urethrotomy and bilateral ureteroneocystostomy in 12-year-old boy.
