Managing patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) begins with a differential diagnosis; and quantifying BPH / LUTS via the AUA symptom index. Evaluating symptoms such as incomplete emptying, straining, and stop-start urination can be achieved with a combination of portable ultrasound bladder volume measurement and a uroflow exam. This combination also may be useful to monitor the progress of pharmacotherapy.
