Hypospadias is a common malformation of fetal development, most often noticed in the penis, in which the urethra does not open from its usual location on the head of the penis, or in the middle of the vulva in females. It is the second most common birth defect of the male reproductive system, affecting about one in 250 males at birth, and up to 4 percent of newborn males when milder cases are counted. Roughly 90 percent of male cases are distal, with the opening on or near the glans, while the rest are proximal, with the opening on the shaft near or within the scrotum. The foreskin is usually underdeveloped, and a downward bend of the penis called chordee may be present, found in 10 percent of distal and 50 percent of proximal cases at the time of surgery.

Treated By: Hypospadias Repair, Lead (695522)
Hypospadias repair is done under general anesthesia, most often supplemented by a nerve block to the penis or a caudal block to reduce the general anesthesia needed, and to minimize discomfort after surgery.
