The variation in urodynamic practice in the United Kingdom.

The object of this study was to determine the variation in urodynamic practices in the United Kingdom. One hundred questionnaires were sent to units known to be performing urodynamic investigations. It was obvious that there was a significant variation in practices with only 51% of units having a protocol for what tests should be performed, under what circumstances and how. Standardisation of urodynamic variables may result in a greater consistency of diagnosis, allowing easier comparisons of treatment regimes and outcomes.
