[Diagnostic procedures and diagnostic strategy for lower urinary tract symptoms/benign prostatic hyperplasia : An overview]. / Diagnostik und diagnostische Strategie beim benignen Prostatasyndrom : Ein Überblick.

ABSTRACT

BACKGROUND: Lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH) is the most common condition affecting the lower urinary tract of men. Evidence-based assessment is the basis for an ideal treatment approach. OBJECTIVES: To provide an overview of the current status of diagnostic measures for LUTS/BPH. MATERIALS AND METHODS: Descriptive review of the literature on the diagnosis of LUTS/BPH. RESULTS: A medical history inquiring about LUTS/BPH symptoms and burden as well as a standardized and validated symptom questionnaire such as the International Prostate Symptom Score (IPSS) are the basis of the assessment. A physical examination including a rectal exam and the ultrasonography of the lower and upper urinary tract are also part of the basic diagnostic workup. Prostate size is ideally measured by transrectal ultrasound. Serum prostate-specific antigen measurement may help to estimate the prostate size and the risk fo progression. It can also be helpful in the detection of prostate cancer. Urine dipstick or sediment is used to exclude urinary tract infection, hematuria, or glucosuria. Voiding dysfunction can be detected by uroflowmetry. In addition to the aforementioned examinations, further tests such as frequency-voiding charts, multichannel urodynamic evaluation, measurement of detrusor wall thickness and X­ray imaging of the upper urinary tract as well as a cystoscopy may be offered if needed. CONCLUSIONS: Diagnostics of LUTS/BPH consist of basic exams as well as optional exams and can be used to assess the progression risk, to identify complications and to offer the ideal treatment.
