A cleft urinary canal in men is a rare congenital disease in which a natural opening for urine to exit the bladder does not form. In the international classification of diseases it has code N35. This pathology occurs in approximately 0.8–1.4% of male newborns. With hypospadias, urea is removed through the gap between the two cavernous bodies of the penis. The disease is accompanied by urination disorders and functional disorders in the sexual sphere.
Most often, boys who were born by Caesarean section or were born prematurely suffer from hypospadias. Other reasons for the development of pathology include hereditary predisposition, chronic infections in a woman’s body that lead to damage to the fetal DNA during pregnancy, infectious diseases of the mother’s genital organs, and severe birth injuries in the newborn. Predisposing factors also include toxicosis, distress in a pregnant woman, exposure to alcohol, nicotine, hormones and medications on the fetus.
