Relevance:
Benign prostatic hyperplasia (BPH) is one of the most common urological diseases among men. Despite the noticeable positive effects of pharmacotherapy on the quality of urination in BPH, the presence of an intravesical obstruction (IVO) leads to discontinuation of conservative treatment in favor of surgical interventions. One of the features of prostate enlargement is the degree of its intravesical growth (intravascular prostatic protrusion, IPP). According to some studies, IPP value of 10 mm or more is indicative of IVO in virtually all men.
Aim:
To compare transabdominal and transrectal ultrasound measurement of IPP in men with BPH.
Materials And Methods:
The study comprised 108 men aged 69+/-10 years (43 to 93 years) with lower urinary tract symptoms and BPH. Patients underwent a standard urological examination. The shape of the prostate, prostate volume and the measurements of the IPP were assessed using transabdominal and transrectal ultrasound.
Results:
The IPP measurements obtained using transabdominal and transrectal ultrasound were 9.8+/-5.7 mm (1.1 to 28 mm) and 9.3+/-5.3 mm (0.5 to 26 mm), respectively. The IPP measurements evaluated by transabdominal and transrectal ultrasound were found comparable regardless of the prostate volume.
Conclusion:
Similar results in assessing PPI by both ultrasound modalities allow them to be used equally effectively.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
