ما يمكن توقعه
قبل الإجراء
You may be asked to do the following:
- التحدث مع طبيبك عن الأدوية الخاصة بك. قد يطلب منك التوقف عن تناول بعض الأدوية تصل إلى أسبوع واحد قبل العملية مثل:
- الأدوية المضادة للالتهابات (مثل الأسبرين)
- سيولة الدم, مثل كلوبيدوجريل (بلافيكس) أو الوارفارين (الكومادين)
- Begin taking an antibiotic if advised by your doctor.
- Use an enema several hours before the procedure.
- If you will be getting general anesthesia, do not eat or drink anything after midnight.
التخدير
The type of anesthesia depends on the method that your doctor uses:
- Transurethral biopsy and perineal biopsy:
- General anesthesia —blocks pain and keeps you asleep through the surgery, given through an IV in your hand or arm
- Local anesthesia—just the area that is being operated on is numbed, given as an injection and may also be given with a sedative
- Transrectal prostate biopsy—local anesthesia
وصف الإجراء
Your doctor will use one of the following methods to do the biopsy:
- Transrectal biopsy (most common method)—Your doctor will insert a small ultrasound device into the rectum. This device will produce sound waves to create an image of the prostate. These images will help guide placement of the needle. Your doctor will then insert the needle through the wall of your rectum and into the prostate gland.
- Transurethral biopsy—Your doctor will insert a lighted flexible tube through the penis into the urethra. The urethra carries urine from the bladder. Your doctor will get the biopsy with a cutting loop that is passed through the flexible tube.
- Perineal biopsy—Your doctor will make a small incision in the perineum. The perineum is the area between the scrotum and the rectum. The doctor will insert a small needle into the prostate gland to get the biopsy.
