[Urethral pain syndrome: fact or fiction--an update].
BACKGROUND
Urethral pain syndrome is a symptom complex including dysuria, urinary urgency and frequency, nocturia and persistent or intermittent urethral and/or pelvic pain in the absence of proven infection. These symptoms overlap with several other conditions, such as interstitial cystitis bladder pain syndrome and overactive bladder. Urethral pain syndrome may occur in men but is more frequent in women.


METHODS
The exact etiology is unknown but infectious and psychogenic factors, urethral spasms, early interstitial cystitis, hypoestrogenism, squamous metaplasia as well as gynecological risk factors are discussed. These aspects should be ruled out or confirmed in the diagnostic approach. Despite the assumption of a multifactorial etiology, pathophysiologically there is a common pathway: dysfunctional epithelium of the urethra becomes leaky which leads to bacterial and abacterial inflammation and ends in fibrosis due to the chronic impairment.


METHODS
The therapeutic approach should be multimodal using a trial and error concept: general treatment includes analgesia, antibiotics, alpha receptor blockers and muscle relaxants, antimuscarinic therapy, topical vaginal estrogen, psychological support and physical therapy. In cases of nonresponding patients intravesical and/or surgical therapy should be considered. The aim of this review is to summarize the preliminary findings on urethral pain syndrome and to elucidate the diagnostic and therapeutic options.
