The enlarged prostate puts pressure on the urethra, which drains urine out of the bladder. Typical symptoms of prostate enlargement are: delayed and weakened stream of urine, feeling urgent to urinate, feeling of incomplete emptying of the bladder after urinating, pollakiuria. If these ailments occur, a urologist should be consulted who will perform an ultrasound of the prostate and assess the degree of possible prostatic hyperplasia.

A TRUS test is a type of ultrasound scan performed transrectally. The TRUS examination allows very accurate visualization of changes in the prostate, because the ultrasound head located in the rectum is very close to the prostate. During the examination, the patient lies on his side. The examination takes approximately 20 minutes.

A few hours before the examination, it is advisable to do an enema. This will improve the patient's own comfort and make it easier for the doctor to perform the examination.
