title: [Urethral meatal stenosis in boys easily overlooked].
abstract: Three boys aged 8, 5, 3 and 9 years, respectively, appeared to have urethral meatal stenosis. In the first patient this appeared during a check-up following treatment for balanitis. Patient history revealed that his micturition duration was longer than before. In the second patient, who underwent surgical correction for hypospadia, it was discovered because he took longer to urinate than his brother. In the third patient stenosis was observed during an appointment for a retracted testicle; he had been circumcised earlier for cultural reasons. Meatomy was performed under anaesthesia in all 3 patients, after which the micturition duration and stream velocity were normal. The third patient continued to have an extremely large bladder capacity and residual volume. Meatal stenosis may lead to obstructive uropathy, urinary tract infection and eventually damage to renal parenchyma. Symptomatic presentation can be late. Diagnostic tests include urine analysis and culture, and uroflowmetry. Visual inspection by spreading the meatal dimple to visualise a pinhole urethra cannot be overemphasised.
