Our Summary

Researchers conducted a study to analyze the noise levels produced by prostate biopsy devices. To do this, they tested five different brands of devices in a lab and three brands in a real-world medical setting. They measured the noise levels at distances of 50 cm and 100 cm from the devices.

In the lab, they found that the average noise level ranged between 104.3 and 121.3 decibels (dB). Amongst all the devices, the Monopty device made the loudest noise, producing sounds between 114.8 and 122.4 dB.

In the clinical setting, they found no significant differences in the noise levels produced by the devices when used on different targets. Furthermore, the distance from the device (either 50 cm or 100 cm) did not affect the noise levels produced. Again, the Monopty device was found to be the loudest, generating sounds between 110 and 127 dB.

The researchers concluded that biopsy devices produce high levels of noise and suggested that medical personnel performing these procedures should consider using hearing protection. While the noise from these devices may not cause permanent hearing loss, it could still potentially harm their hearing.

Doctor’s Tip

A doctor might advise a patient undergoing a prostate biopsy to be aware that the procedure can be noisy, and to consider bringing earplugs or asking for ear protection during the biopsy to reduce any potential discomfort or risk to their hearing.

Suitable For

Patients who are typically recommended prostate biopsy include those with abnormal prostate-specific antigen (PSA) levels, abnormal digital rectal exam (DRE) findings, or a family history of prostate cancer. Additionally, patients who have symptoms such as frequent urination, difficulty urinating, or blood in the urine may also be recommended for a prostate biopsy to rule out prostate cancer.

Timeline

Before Prostate Biopsy:

  • Patient undergoes initial consultation with urologist to discuss symptoms and determine if biopsy is necessary
  • Patient may undergo additional tests, such as PSA blood test or MRI, before biopsy is scheduled
  • Patient receives instructions on how to prepare for the biopsy, such as stopping blood-thinning medications and fasting
  • Patient may receive sedation or local anesthesia before the procedure

During Prostate Biopsy:

  • Patient lies on their side with knees drawn up to chest
  • Urologist inserts ultrasound probe into rectum to visualize prostate
  • Urologist uses biopsy needle to take small tissue samples from different areas of the prostate
  • Patient may feel discomfort, pressure, or pain during the procedure
  • Procedure typically takes 10-20 minutes

After Prostate Biopsy:

  • Patient may experience mild discomfort, bleeding, or blood in urine or semen for a few days after the biopsy
  • Patient may be advised to avoid strenuous activities for a few days
  • Patient may receive biopsy results within a week or two
  • If biopsy results show cancer, patient may undergo further tests or treatments, such as surgery, radiation, or hormone therapy

Overall, the prostate biopsy procedure can be a stressful and uncomfortable experience for the patient, but it is an important step in diagnosing prostate cancer and determining the best treatment plan.
