General findings

In addition to patient self-reported symptoms various standard tests are performed to check for patient health (e.g. PSA test), bacteria and hyperplasia. All these are usually negative or within the normal range. The CPPS patient is 'healthy and well' despite pain, tiredness, frequency etc. And that quality of life is affected by conditions affecting micturition has been concluded repeatedly(1). It may be noted that older men with LUTS (lower urinary tract symptoms)(2) seem more prone to injuries from falls.(3)
