}}</ref> Meatal stenosis is a relatively common acquired condition occurring in 10%-20% of males who are [[Circumcision| circumcised]]. This disorder is characterized by an upward deflected, difficult-to-aim urinary stream and, occasionally, dysuria and urgent, frequent, and prolonged urination. Surgical meatotomy is curative. | }}</ref> Meatal stenosis is a relatively common acquired condition occurring in 10%-20% of males who are [[Circumcision| circumcised]].

Serial dilatation results in small tears of the meatus, which are followed by secondary healing. In the long term, this creates a tighter stricture at the tip of the penis; therefore, this procedure is discouraged. | Serial dilatation results in small tears of the meatus, which are followed by secondary healing.

Meatotomy is the definitive treatment for meatal stenosis. Meatotomy is a simple procedure in which the ventrum of the meatus is crushed (for hemostasis) for 60 seconds with a straight mosquito hemostat and then divided with fine-tipped scissors. | Meatotomy is the definitive treatment for meatal stenosis.
