SpecialtyUrology

Lower urinary tract symptoms (LUTS) refer to a group of clinical symptoms involving the bladder, urinary sphincter, urethra and, in men, the prostate. The term is more commonly applied to men[1]—over 40% of older men are afected[2][3][4][5]—but lower urinary tract symptoms also affect women.[6] The condition is also termed prostatism in men, but LUTS is preferred.[7]

Symptoms and signs

Symptoms can be categorised into:

Filling (storage) or irritative symptoms

Voiding or obstructive symptoms

As the symptoms are common and non-specific, LUTS is not necessarily a reason to suspect prostate cancer.[7] Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific diagnosis.[10] Also, recently a report of lower urinary tract symptoms even with malignant features in the prostate failed to be associated with prostate cancer after further laboratory investigation of the biopsy.[9]

Causes

Diagnosis

The International Prostate Symptom Score (IPSS) can be used to gauge the symptoms, along with physician examination. Other primary and secondary tests are often carried out, such as a PSA (Prostate-specific antigen) test,[16] urinalysis, ultrasound, urinary flow studies, imaging, temporary prostatic stent placement, prostate biopsy and/or cystoscopy.

Placement of a temporary prostatic stent as a differential diagnosis test can help identify whether LUTS symptoms are directly related to obstruction of the prostate or to other factors worth investigation.[citation needed]

Treatment

Treatment will depend on the cause, if one is found. For example; with a UTI, a course of antibiotics would be given[medical citation needed]; appropriate medication would be administered to treat benign prostatic hyperplasia.

Lifestyle changes

Other treatments include lifestyle advice; for example, avoiding dehydration in recurrent cystitis.[citation needed]

Men with prostatic hypertrophy are advised to sit down whilst urinating.[17] A 2014 meta-analysis found that, for elderly males with LUTS, sitting to urinate meant there was a decrease in post-void residual volume (PVR, ml), increased maximum urinary flow (Qmax, ml/s), which is comparable with pharmacological intervention, and decreased the voiding time (VT, s).[18] The improved urodynamic profile is related to a lower risk of urologic complications, such as cystitis and bladder stones.[18]

Physical activity

Physical activity has been recommended as a treatment for urinary tract symptoms. A 2019 Cochrane review of six studies involving 652 men assessing the effects of physical activity alone, physical activity as a part of a self-management program, among others.[19] The evidence from this review states that there are important uncertainties whether physical activity is helpful in men experiencing urinary symptoms caused by benign prostatic hyperplasia.[19]

Medications

With benign prostatic enlargement causes of LUTS, people may be offered a variety of medications (as a single drug or combining them) when there are persistent moderate symptoms:[20]

If medical treatment fails, or is not an option; a number of surgical techniques to destroy part or all of the prostate have been developed.[citation needed]

Surgical treatment

Surgical treatment of LUTS can include:

Epidemiology

  • Prevalence increases with age. The prevalence of nocturia in older men is about 78%. Older men have a higher incidence of LUTS than older women.[24]
  • Around one third of men will develop urinary tract (outflow) symptoms, of which the principal underlying cause is benign prostatic hyperplasia.[25]
  • Once symptoms arise, their progress is variable and unpredictable with about one third of patients improving, one third remaining stable and one third deteriorating.[citation needed]
