Lower Urinary Tract Symptoms (LUTS)
Definition of LUTS
The acronym LUTS stands for lower urinary tract symptoms. It is used collectively for the following complaints regardless of their cause:
- Storage symptoms: Dysuria, urgency, urge incontinence, nocturia and frequency.
- Emptying symptoms: weak urinary stream, hesitancy, straining during urination, interrupted urine stream, dribbling, residual urine, urinary retention.
Differential Diagnosis
The most common cause of LUTS in men over 50 years is benign prostate hyperplasia (BPH), but many other diseases are also possible. The diagnostic challenge is to clarify the cause of voiding symptoms. Only after exclusion of other possibilities, BPH can be made responsible for LUTS:
- Diseases of the prostate: BPH, prostatitis, prostate cancer.
- Diseases of the urethra: urethritis, stricture, carcinoma, calculi, foreign bodies, phimosis.
- Diseases of the bladder: cystitis, bladder tumor, bladder stone, bladder neck sclerosis, detrusor sphincter dyssynergia (DSD), neurogenic bladder dysfunction.
- Other causes: psychological causes, polyuria, cardiac diseases, lung diseases.
