Which condition can be assessed with a pelvic ultrasound in men?

A pelvic ultrasound in men is primarily used to assess organs located in the pelvis, which includes the bladder and prostate. Prostate enlargement, also known as benign prostatic hyperplasia (BPH), and other abnormalities such as tumors or inflammatory conditions can be effectively visualized using this imaging technique. The ultrasound allows for a non-invasive approach to evaluate the size and structure of the prostate, which is crucial for diagnosing various prostate-related conditions.

In contrast, kidney stones and gallbladder disease typically require imaging of the upper abdomen and renal areas, where other imaging modalities such as abdominal ultrasounds or CT scans are more suitable for evaluation. Testicular torsion involves the reproductive organs, which are often assessed using scrotal ultrasounds rather than pelvic ultrasounds focusing on the pelvic cavity. Therefore, prostate-related evaluations are the primary focus of using pelvic ultrasounds in men, making this option the correct choice.
