KEY FACTS

  • Terminology

      • Top Differential Diagnoses

        • Pathology

          TERMINOLOGY

          • Abbreviations

            • Benign prostatic hyperplasia (BPH)
          • Synonyms

            • Prostatism; glandular and stromal hyperplasia
            • Hyperplasia is correct term since BPH is characterized by increased number of stromal and glandular cells (not hypertrophy, which means increase in size)
          • Definitions

            • BPH reserved for histopathological pattern of smooth muscle and epithelial cell proliferation in TZ and periurethral glands
            • Prostatism historically applied to almost all symptoms of micturition disorder in older men
              • Term implies prostate as cause of problem, which may not be the case (e.g., neurologic abnormalities)
            • Lower urinary tract symptoms (LUTS) applies to any patient with urinary symptoms, regardless of age or sex; does not specify underlying etiology
              • Storage LUTS: Frequency, urgency, nocturia
              • Voiding LUTS: Hesitancy, straining, slow stream, intermittent or interrupted flow, terminal dribbling, sensation of incomplete emptying
            • BPE: Benign prostate enlargement: Usually presumptive diagnosis based on prostate size
            • BPO: Benign prostate obstruction: Enlarged gland with obstruction that has been proven by urodynamics
            • BOO: Bladder outlet obstruction: Generic term for any cause of subvesical obstruction, including BPO
