The improvement in uroflow and postvoid residual urine in children after urethral meatotomy for meatal stenosis. The hypothesis is that there is an improvement in both parameters, thus justifying the procedure.

Urethral meatal stenosis is a known complication of circumcision occuring in up to 3% of newborns undergoing circumcision. It is customary to perform a meatotomy in order to prevent bladder outlet obstruction, although bladder outlet obstruction has never been proven and improvement has only been proved in a single, small, retrospective study. Our intention is to evaluate the improvement in objective parameters (uroflow and postvoid residual urine) after urethral meatotomy by measuring these parameter before the procedure, one month after the procedure and one year after the procedure. Symptoms assessment will also be performed.

Inclusion Criteria:

• Toilet trained children
• Before puberty
• No other urologic disease that might affect the measurements
• Primary (first) repair

Exclusion Criteria:

• Children unable to urinate on command
• Children that have started their sexual puberty
• Children with other urologic disease that might affect the study measurements
• Recurrent stenosis after previous repair

Toilet trained children, before puberty, scheduled for urethral meatotomy for the treatment of urethral meatal stenosis.
