Abstract
To predict the duration of postoperative bladder drainage required after incontinence surgery, 30 patients were studied preoperatively using voiding-simultaneous urethrocystometry. Based on changes in bladder, urethral, and abdominal pressures, patients were divided into 3 groups. Patients who demonstrated adequate bladder contraction during voiding did not need prolonged catheterization (P < 0.005). Patients who did not demonstrate adequate detrusor contractor and used Valsalva maneuver during voiding were at 12 times greater risk of requiring prolonged postoperative catheterization (P < 0.05). Changes observed in urethral and abdominal pressures individually during voiding were not significant predictors of the need for prolonged catheterization. Preoperative knowledge of voiding mechanisms can predict postoperative catheterization need.
