BPH is most often diagnosed based on the patient’s symptoms (typically assessed using the International Prostate Symptom Score questionnaire), their medical history (e.g., prior surgeries, medication use, sexual history, fluid consumption), and a digital (i.e., finger) rectal exam.[1] To differentiate BPH from other conditions that can cause lower urinary tract symptoms, a urinalysis is also commonly performed to detect material in the urine associated with metabolic disorders, renal dysfunction, or urinary tract infection.[2]
