Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Well, the treatment depends on the cause of urinary retention and causes include an obstruction in the urinary tract such as an enlarged prostate or bladder stones, infections that cause swelling or irritation, nerve problems that interfere with signals between the brain and the bladder, medications, constipation, urethral stricture, or a weak bladder muscle. Tests to diagnose urinary retention include taking a urine sample, bladder scan, cystoscopy, X-ray and CT scan, a blood test for prostate-specific antigen (PSA), prostate fluid sample test, and urodynamic tests to measure the bladder s ability to empty steadily and completely. Treatment for urinary retention includes catheterization, treating prostate enlargement, and surgery and this should be discussed with your doctor after the right cause is found. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ivan R. Rommstein
