Hyposadadias is a birth defect in which the urethra opens on the underside of the penis instead of the tip. The lower the opening, the more it can change how urine leaves the body.
The main sign is an off-target stream. Urine sprays downward or fans out, making it hard to aim straight into a toilet.
The penis may look bent downward, especially during an erection, because the foreskin is missing on the underside and pulls the shaft.
If the opening is near the scrotum, urine can trickle between the legs or soak the underwear even after shaking.
Some boys need to sit to void, and the underwear often has wet spots or a faint urine smell by midday.
Split spraying is common. The stream may divide into two or drip for several seconds after voiding is finished.
