排尿障礙治療中心 版權所有 Role of Uroflowmetry and Postvoid residual urine in SUI A high Qmax with little PVR usually indicate normal detrusor contractility A low Qmax with straining pattern may imply poor relaxing urethral sphincter or low detrusor contractility Large residual urine indicates inadequate voiding efficiency Flow pattern is important in bladder function
