Learn more about Men Pelvic Ultrasound
Men sonography, or ultrasound examination, is a medical imaging technique that allows viewing inside the body. It is done using a transducer, also called a ‘probe’, which emits high frequency sound waves (ultrasounds). When reflected by the body’s internal structures, these waves produce images. Sonography can also be useful to guide the punction of an organ, an intra-articualr injection or a biopsy.
Since ultrasounds are absorded by gas and stopped by hard structures such as bone and calcification, some internal organs are not well viewed with sonography which, therefore, is not the primary choice for examining them. It is the case for the lungs, intestines, stomac, and brain. Unlike MRI, CT scan and X-ray, no ionizing radiations are used during sonography. It is painless and non-invasive, which makes it safe for repetitive use.
The sonography is performed by a specialized medical imagery technologist, called a sonographer, or a radiologist. The patient lies topless on their back or side. A gel is applied to the skin to help with the ultrasounds’ transmission and ease the movements of the probe. This type of examination is usualy painless, but the patient may experience some discomfort as the sonographer presses with the probe.
The pelvic ultrasound for men is the ideal examination to explore the organs and tissues inside the pelvic cavity such as the bladder, prostate and surrounding tissues. The sonographer sweeps the pelvic surface with the probe to investigate the organs size, shape and anomalies in their structures. Occasionnaly, the ultrasound can be performed throught the rectum using a specialised probe to get more detailed images of the prostate. This intervention may be risky and must be done at a hospital facility. The waves are reconstructed into images on a screen as the sonographer or radiologist is carefully examining them.
The pelvic ultrasound for men can provide much information on the organs located inside the pelvic cavity that are more complete than regular X-rays.
The pelvic ultrasound examination mainly explores:
• Bladder : Shape, size when full, size when emptied, post-void residu, wall, urinary jets;
• Prostate: Size, shape, signs of infections, tumors, calcifications;
Sonography can also help to show abnormal lymph nodes (lymphadenopathy) or the presence of free fluids (ascitis), blood and suspicious masses.
To proceed to the pelvic ultrasound, the patient must have a full bladder. They must drink one liter of clear liquid one hour prior to the examination. Then, the patient must not urinate to leave time for the bladder to fill up.
The pelvic ultrasound for men takes about thirty minutes. A detailed report is written by the radiologist and is then transmitted to the patient’s physician who will, if necessary, make decisions regarding treatment and/or further investigations.
