Overactive bladder induces transient hypertension.

Study 1: the mean systolic pressure was significantly higher at urgency or SDV than at the other measurement points in the DO group (161.3 ± 23.2 vs. 134.5 ± 16.3, 137.8 ± 15.3, or 139.5 ± 14.8 mmHg). Study 2: the mean systolic pressure was significantly higher at the measurement points before micturition than at the points unrelated to micturition in the OAB group (159.7 ± 24.9 vs. 124.9 ± 13.8 mmHg). In conclusion, DO or urgency induces a transient increase of blood pressure, suggesting that OAB induces a type of hypertension before micturition.
