NON-INFECTIOUS CAUSES OF PAINFUL URINATION
There are also numerous non-infectious causes of painful urination. Urine contains waste products and if the urine concentration is too high because of insufficient hydration, one may experience burning. This happens particularly with the first urination of the day, when the urine is most concentrated because of the relative dehydration from the hours spent sleeping without consuming liquids. During the process of prostate radiation therapy as treatment for prostate cancer, radiation-induced inflammatory changes of the prostate may occur, resulting in irritative lower urinary tract symptoms and painful urination. On occasion, a long-term consequence of pelvic radiation therapy is radiation cystitis, that can manifest with bleeding, irritative lower urinary tract symptoms and painful urination. Interstitial cystitis, a painful inflammatory condition of the bladder that may severely impact one’s quality of life, causes painful urination, pelvic pain and urinary frequency.
Conditions that directly impacts the anatomy or function of the urethra can give rise to painful and difficult urination. These include the following: urethral stricture (scar tissue within the urethra), a urethral stone (lodged within the urethral channel), urethral diverticulum (an out-pouching from the urethra), atrophic urethritis (changes of the urethra that accompany menopause), and urethral trauma (following sexual intercourse, childbirth, straddle injuries and commonly from urinary catheters and following transurethral surgery). Pelvic floor dysfunction with hyper-tensioning of the pelvic floor muscles can cause painful urination as well as many other urinary, bowel, sexual and pelvic symptoms.
DIAGNOSING PAINFUL URINATION (DYSURIA)
Examination of the urethra, penis, testes and prostate in males and a pelvic exam in females, along with urinalysis and urine culture are imperative. If there is urethral discharge accompanying the painful urination and/or a history of unprotected sex, a STI screen is appropriate. Urinalysis and culture will rule out urinary infection. Depending on associated urinary symptoms, cystoscopy (visual inspection of the urethra and bladder with a tiny fiberoptic telescope) and imaging tests may be indicated.
PAINFUL URINATION TREATMENT
If the urine is hyper-concentrated, increasing fluid intake will improve the situation. Urinary infections are usually easily managed with a course of antibiotics. Urinary tract analgesics/antispasmodics are helpful for temporary relief of painful urination associated with infections. Prostatitis and Skenitis will generally require a more prolonged course of antibiotics. STIs are typically easily treated with the appropriate antibiotic or antiviral. Yeast infections are readily treated with anti-fungal medications. At times, a prostate relaxant medication can be helpful for the urinary difficulties associated with prostatitis, whether infectious or radiation induced. Anti-inflammatories are often useful as well. Interstitial cystitis is a complex situation with multiple potential treatment options. Atrophic urethritis can be addressed with topical estrogen. If a stone, stricture or diverticulum is found within the urethra, surgery is often indicated. For pelvic floor dysfunction, pelvic floor physical therapy can be extremely helpful to foster relaxation and “down-training” of the spastic pelvic muscles.
