Had urodynamics test but couldn't do final part pee with catheter in. As was dizzy and sick. Will this ruin my diagnosis?

Consult urologist. Dr who performed or ordered test can tell you. Many bladder or urinary problems requiring urodynamics can be accurately diagnosed with need to urinate with catheter in place. Will not be able to diagnose detrusor sphincter dyssynergia (when urinary sphincter fails to relax when bladder contracts during voiding) Can still diagnose bladder capacity & pressures, also involuntary bladder contractions.
