Complications of BEP are relegated to secondary obstruction caused by enlarged prostate to the flow of urine from the bladder to the urethra.
- Retention of urine: Either acute or chronic retention of urine occurs due to the obstruction caused by the enlarged prostate at the neck of the bladder. Catherization is required most of the times to relieve the obstruction.
- Infection of urinary tract: Secondary to retention of urine, various disease-causing microorganisms present in stagnated urine can cause recurrent urinary tract infections. Chronic inflammation of prostate cause prostatitis and bladder infections leading to blood in the urine.
- Bladder stones: Various minerals are present in the urine, which over a period of time, due to stagnation of urine, get aggregated to form large bladder stones.
- Damaged kidneys: Chronic retention of urine leads to backflow of urine into the kidneys, causing recurrent infections and damage to their structure.
