Abstract:
Results of flowmeter studies in 145 patients before and then immediately after urodynamic exploration were unchanged in 80% of women and 72% of men. Abnormal results on flowmetric examination, detected in 18% of cases prior to urodynamic studies, were assessed as normal during follow-up urodynamic tests. These findings raise the question of the validity of flowmeter parameters determined during urethrocystometric exploration.
