Abstract
OBJECTIVE: To evaluate the utility and accuracy of transabdominal ultrasound in the estimation of postmicturition residual urine in patients with symptomatic benign prostatic hyperplasia (BPH). METHODS/ RESULTS: The postvoid residual urine was evaluated in 50 selected patients with BPH. The mean age was 60 years. The bladder volume was estimated in all patients and ranged from 210-540 ml (average 339.2). After voiding, the amount of urine was measured and ranged from 145-350 ml (average 223.5). Then the postmicturition residual urine was evaluated by ultrasound (range 60-264 ml; average 112.86) and compared with the bladder catheter measurements (range 50-265 ml; average 112.6), which showed a minimum difference of +/- 3.84 ml SD. CONCLUSION: Transabdominal ultrasound is a good alternative in the estimation of postmicturition residual urine.
