Congenital narrowing of the urethra
Medical expert of the article

[Diagnostics of the congenital narrowing of the urethra
The diagnosis is made according to the data of urethrography (descending and ascending): in the proximal parts the urethra is enlarged.
Such signs as trabecularity of the walls of the bladder, false diverticula, residual urine, are detected only with a pronounced stenosis.
Differential diagnosis of congenital narrowing of the urethra with acquired stenosis (most often occurring in girls) due to recurrent cystitis and urethritis is necessary.
Calibration of the urethra in girls by bougies (from a smaller size to a larger one according to age) allows only to suspect stenosis, and not to establish the correct diagnosis, since the caliber of the urethra is very variable.

Treatment of the congenital narrowing of the urethra
With a mild obstruction, narrowing of the urethra with the help of bougie is treated. Patients with stenosis of the distal urethra canal are shown meatotomy (dissection of the outer orifice). In this case, a catheter is left in the urethra for a few days, the size of which corresponds to the age of the child. In the case of diagnosis of acquired metastal stenosis, conservative treatment of the disease is performed.
