Abstract

Urodynamics include several investigations of the bladder-sphincter complex. Uroflowmetry is easy to perform but interpretation might be hazardous in very young children: in urethral obstruction, it shows a decrease in the maximal flow rate and an increase in the voiding time: such an investigation has no specific value in case of posterior urethral valves since it can be even normal in case of obstruction. Nevertheless, uroflowmetry is of great interest with respect to postoperative follow-up. Other investigations of the bladder and of the urethra are more aggressive and not so helpful in diagnosing obstruction: they might be helpful in understanding and managing persistent voiding disorders after posterior urethral valves section.
