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.

Nursing Assessment of the Genitourinary System III: Percussion and Auscultation
2
The genitourinary system maintains the body's fluid balance, waste excretion, and overall homeostasis. Proper assessment is essential for early detection of disorders, with percussion and auscultation integral to this evaluation. These methods help identify signs of kidney or bladder issues and provide important diagnostic clues.Percussion for Kidney TendernessPercussion is used to assess tenderness and detect kidney and bladder abnormalities. A common method for determining kidney tenderness...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
