ESWL – External Shockwave Lithotripsy
Kidney stones are little and hard deposits that can develop in the kidneys. Lithotripsy, often referred to as extracorporeal shock wave lithotripsy (ESWL), is the most ordinary procedure for the management of kidney stones (renal lithiasis). It uses shock waves to break up stones that form in the kidney, bladder or ureter,enabling easy passage of the fragments out of the body within the urine.
During lithotripsy you will lie on a water-filled cushion. High-energy sound waves that are formed outside of the body travel through the body until they hit the kidney stones and break them into small pieces. You may feel a tapping sensation on your skin as the shockwaves enter the body.
A tube is inserted throughout your bladder or your back into your kidney to help drain urine from your kidneys until all the tiny fragments of stone pass out of your body. The tube may be inserted before or after the procedure. The procedure takes about 45 to 60 minutes to complete.
You will be taken to the recovery room to be monitored for a couple hours after the procedure. Lithotripsy is usually an outpatient procedure where you are capable to go home on the same day. You can usually resume regular activities within a day or two.You may experience pain when the stone fragments pass, which occur soon after treatment and may last for 4 to 8 weeks. Oral pain medications are prescribed to relieve pain. You will be instructed to drink plenty of water to help clear the stone fragments out of your urinary system.
Lithotripsy is considered a relatively safe procedure, but as with any medical procedure there may be risk involved.
Some risks related with lithotripsy include:
•Bleeding in or around the kidney
•Failure to remove the stones requiring additional treatment
•Pain if a stone fragment blocks the flow of urine
•Kidney damage or a decrease in kidney function
•Ulcers in your stomach or intestine
Transrectal ultrasound is test to examine the prostate gland; because the prostate gland is sitting right against the rectum, very exact size measurements can be obtained.
A transducer probe is lightly inserted into the rectum through the anus. The prostate gland dimensions are measured, the inside of the prostate is examinee carefully for abnormalities.
The main purpose of the transrectal ultrasound is to allow the accurate estimation of prostate size. The size of the prostate size is important in determining medical and surgical treatment.
Digital rectal examination and abdominal ultrasound can also give a prostate size estimate, but transrectal ultrasound is more exact. MRI scans can also give an accurate prostate size estimation.
The prostate gland is an organ found in men, surrounding the neck of the urinary bladder. The gland grows with age, but if it grows too big, it can exert stress on the urethra (tube that drains urine), and may obstruct the flow of urine. This condition is called benign prostatic hypertrophy (BPH) and cause urinary problems, such as difficulty in emptying the bladder and frequent urinary infections.
TURP is performed under general or spinal anesthesia. Your surgeon inserts the resectoscope into your penis, and advances it through the urethra (the tube that carries urine from the bladder out of the body). The cutting tool is guided through the resectoscope and is heated with the help of an electric current. The heated wire is used to cut and remove the excess tissue. At the end of the procedure, the blood vessels are sealed carefully and the bladder is irrigated to flush out piece of the respected tissue. The complete surgery takes about 1 hour and you may have to stay in hospital for 2 to 3 days after the procedure.
