[The use of transabdominal ultrasound in the estimation of postmicturitional residual urine].
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).


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.


CONCLUSIONS
Transabdominal ultrasound is a good alternative in the estimation of postmicturition residual urine.
