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.
Cocaine levels peak in the blood about 30 minutes after you take it. But cocaineâs action in and on the body depends upon several factors. Dosage, mode of administration, single vs. multiple use. But in general, cocaine and its metabolites stay in the system and can be detected 2-4 days after use.ery low concentrations of cocaine may be detected in urine during the initial few hours after use. In general, cocaine metabolites like benzoylecgonine can be detected in urine 2â4 days after use for sporadic users and up to 12 days after use for chronic users or following a binge.
