摘要
ObjectiveThis study aimed to determine if routine assessment of patients after onabotulinumtoxinA injections for overactive bladder is necessary to detect clinically significant voiding dysfunction. MethodsThis retrospective cross-sectional cohort study analyzed patients who underwent intravesical injection of onabotulinumtoxinA for overactive bladder during a 4-year period. Patients were included for analysis if they returned for an office follow-up visit within 1 month of administration. Baseline demographic data; procedural details; postvoid residual volumes; abnormal postprocedure voiding symptoms, including urinary frequency, pain, or inability to void; urinary tract infections; and initiation of intermittent self-catheterization were recorded. Descriptive statistics, point-biserial and Pearson correlation analyses were performed. ResultsTwo hundred thirty-seven injections were included in our analysis. Fifteen encounters, from 13 patients, required the initiation of intermittent self-catheterization (6.3%). The median postvoid residual in those treated with intermittent self-catheterization was 300 mL (min, max: 200, 750 mL); all had received 100 units of onabotulinumtoxinA. The most common symptom among those requiring intermittent self-catheterization was urgency (n = 13; 87%), whereas 93% (n = 14) had at least 1 bothersome symptom. Correlation analyses showed a weak positive correlation with elevated postvoid residual volume and a history of prolapse repair (r = 0.269, P = 0.004), and prior pelvic surgery (r = 0.205, P = 0.029). ConclusionsClinically relevant urinary retention that required intermittent self-catheterization after onabotulinumtoxinA injection for overactive bladder occurred in 6.3% of participants in this sample. The vast majority of patients who required intermittent self-catheterization described symptoms that they were able to self-identify.
