Benign prostatic hyperplasia (BPH), also called benign enlargement of the prostate (BEP or BPE), is a noncancerous increase in size of the prostate. BPH involves hyperplasia of prostatic stromal and epithelial cells, resulting in the formation of large, fairly discrete nodules in the transition zone of the prostate. When sufficiently large, the nodules impinge on the urethra and increase resistance to flow of urine from the bladder.
Cocaine. 1  Cocaine is used as a topical anesthetic; a patient's urine may test positive for benzoylecgonine, cocaine's metabolite for up to 2-3 days following a procedure. In the absence of a medical explanation, a positive UDT for cocaine's metabolite should be interpreted as deliberate use.
1 Bence Jones protein. 2  This is an abnormal protein found in the urine of about 50% of people with a rare type of cancer called multiple myeloma. 3  A urine test is often done when multiple myeloma is suspected. 4  The protein test done during a regular urine test does not check for Bence Jones protein. Other substances that may be checked during a urine test include: 2  Bilirubin. 3  This is a substance formed by the breakdown of red blood cells. 4  It is passed from the body in stool. 5  Bilirubin is not found in urine.
