[Clinical significance of parameters of prostate volume measured by transabdominal ultrasonography in evaluating bladder outlet obstruction].

Objective: To explore the correlation between the parameters of prostate volume (PV) measured by transabdominal ultrasonography and urodynamic results in diagnosing bladder outlet obstruction (BOO).

Methods: 112 BPH patients aged 45-85 underwent transabdominal ultrasonography to measure the superior-inferior diameter (R1) anterior-posterior diameter (R2), and left-right diameter (R3). Urodynamic examination was conducted to record the maximum flow rate (Qmax), detrusor pressure at maximum urinary flow rate (Pdet.
