How is meatal stenosis diagnosed?
A doctor’s physical exam and measurements of the width of the meatus with special instruments can show if meatal stenosis is present. A small, narrow meatus means that the passage is partly blocked.
However, there are natural differences in meatal widths in different males, so a narrow meatus does not necessarily indicate stenosis. The health of the patient, not just the appearance of the meatus, is the key to deciding whether stenosis is present or not. Observation of the patient during urination can determine whether the urine stream is straight or not. Also, the taking of measurements of the rate of flow can help in making the right diagnosis. An uncontrolled path of a urine stream and spraying of the urinary stream mean that a correction of the meatal stenosis is probably needed.
