A biopsy is a process wherein a doctor collects a small amount of tissue for examination in a laboratory. Biopsies enable doctors to detect many diseases, specifically cancer. In some cases, biopsies help to ascertain the severity or stage of an illness and selection of right treatment. Doctors use various biopsy techniques depending on which organ or tissue requires to be studied.
A biopsy is generally performed in an urologist's office or often in a radiology department. A patient may be asked to take a fleet enema and a spectrum antibiotic like ciprofloxacin(Cipro)immediately prior to the procedure. Additionally, you may be instructed to cease ingestion of aspirin, any anti-inflammatory drugs, warfarin (Coumadin), herbal pills, along with vitamin E a week prior to the biopsy to curtail bleeding.
Patients who generally follow a strong antibiotic course prior to dental treatment should follow the same schedule prior to a prostate biopsy.
These days’ six prostate biopsies are generally conducted in the parasagittal line halfway between the lateral rim and midline of the prostate on both right and left sides from the center, mid gland, and apex. But it seems that six biopsies may not be sufficient for all prostate sizes and configurations, and nevertheless, it has been notices that prostate cancer detection rates are proportional to prostate size in case only six biopsies are conducted.
Currently there are some refinement of the prostate biopsy process, delineating it to prostates of different volumes and shapes. Sextant biopsies are conducted more and more to be exact in most cases and more extended PZ (peripheral zone) biopsy systems may certainly successfully increase cancer detection rates. A reason behind this is that most of prostate cancers begin in the peripheral area of the prostate.
There are three major ways in which this procedure is generally undertaken:
The doctor may facilitate a transrectal ultrasound (TRUS) probe to direct the needles to the suspected site. The probe and needle are inserted via rectum, and guided towards the prostate taking help of ultrasound. After this, using a spring-loaded needle, it "shoots" the prostate and extracts a sample. This procedure could be repeated several times, depending on tumor volume and prostate characteristics.
An alternative is fixed the needle to the doctor's finger, but this is rarely used. The entire process may stretch up to 30 minutes, and can be longer depending on the number of probes.
A lighted scope is sent in the urethra Instead of the rectum and is directed by the doctor to the prostate. After reaching the site, samples are collected.
Another transurethral process is transurethral resection of the prostate (TURP), a surgical procedure facilitated most often to treat men suffering with BPH. Some part of the prostate gland surrounding the urethrais removed. A device with a wire loop at the edge is passed through the penis guided through the urethra to the prostate gland. Electricity is sent through the wire to heat and cut the tissue. A sample of the prostate tissue is taken out during TURP is sent for examination by a pathologist to detect whether any cancer is present.
This entire process may last for 30-45 minutes, or sometimes a little more due to the time spend in guiding the lighted scope.
This type of biopsy is not so frequently performed as previous two, as in this type of biopsy local anesthesia and an incision is made in the perineum, through which the needle is inserted.
The doctor put his hand inside the rectum to hold the prostate. After the prostatic samples are taken, the incision is pressed with a small bandage. The prostate biopsy is done.
