Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...

Summary

Ultrasonography is as effective as fluoroscopy for targeting in Extracorporeal Shock Wave Lithotripsy (ESWL). This method enhances success for non-opaque stones and reduces radiation exposure.

Area of Science:

  • Urology
  • Medical Imaging
  • Nephrology

Background:

  • Urinary stone disease is a prevalent urological condition.
  • Extracorporeal Shock Wave Lithotripsy (ESWL) is a primary treatment for kidney and ureteral stones.
  • Fluoroscopy, traditionally used for ESWL targeting, involves radiation exposure and limitations with non-opaque stones.

Purpose of the Study:

  • To compare the efficacy and outcomes of fluoroscopic versus ultrasonographic targeting in ESWL.
  • To evaluate the advantages and disadvantages of each targeting modality.

Main Methods:

  • A prospective study involving 100 patients with radio-opaque stones undergoing ESWL.
  • Patients were divided into two groups: Group A (fluoroscopic targeting) and Group B (ultrasonographic targeting).
  • Success was defined as stone-free status or ≤4 mm residual stones after up to four sessions.

Main Results:

  • Overall success rates were 66% for men and 78% for women, with no significant gender difference.
  • Success rates for fluoroscopic (Group A) and ultrasonographic (Group B) targeting were 66% and 74%, respectively, with no significant difference.
  • Successful procedures were associated with lower patient weight, smaller stone size, and lower total energy delivered.

Conclusions:

  • Ultrasonography is an effective alternative to fluoroscopy for imaging and targeting during ESWL.
  • Ultrasonographic targeting improves ESWL success rates for non-opaque stones.
  • Ultrasonography minimizes radiation exposure associated with ESWL procedures.
