Abnormalities of the male urethra and webbed penis

Last updated: September 6, 2021

Summarytoggle arrow icon

Abnormalities of the male urethra are common and the need for treatment depends on the condition and the symptoms. Epispadias and hypospadias may result in difficulty urinating and infections, and surgical repair is indicated for restoring functionality and reconstruction of external genitalia. Posterior urethral valves are the most common cause of urinary obstruction in newborn boys and can be associated with hydronephrosis, renal failure, and pulmonary hypoplasia. Early identification by prenatal ultrasound with diagnosis by voiding cystourethrogram allows for cystoscopic valve ablation and relief of the obstruction. However, despite treatment, many patients will develop chronic kidney disease.

Circumcision is contraindicated in boys with hypospadias that includes the foreskin. In these cases, the foreskin may be needed for a skin flap when performing urethroplasty.
