A parathyroid adenoma is a benign tumor of the parathyroid gland. It generally causes hyperparathyroidism; there are very few reports of parathyroid adenomas that were not associated with hyperparathyroidism. [ 1] A human being usually has four parathyroid glands located on the posterior surface of the thyroid in the neck.
Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood. [ 1][ 4] This occurs from a disorder either within the parathyroid glands ( primary hyperparathyroidism) or as response to external stimuli ( secondary hyperparathyroidism ). [ 1] Symptoms of hyperparathyroidism are caused by inappropriately normal or elevated ...
22.1 million (2015) [ 5] Deaths. 16,100 (2015) [ 6] Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material ( renal calculus) develops in the urinary tract. [ 2] Renal calculi typically form in the kidney and leave the body in the urine stream. [ 2]
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [ 1 ] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 ( basophilic) and type 2 ( eosinophilic ).
These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.7 to 2 MHz), but higher the frequency means lower the focusing energy. HIFU treatment is often guided by MRI. Focused ultrasound may be used to dissolve kidney stones by lithotripsy. Ultrasound may be used for cataract treatment by phacoemulsification.
Renal ultrasonography ( Renal US) is the examination of one or both kidneys using medical ultrasound . Ultrasonography of the kidneys is essential in the diagnosis and management of kidney-related diseases. The kidneys are easily examined, and most pathological changes in the kidneys are distinguishable with ultrasound.
Renal hypoplasia. An ultrasound scan of a hypoplastic right kidney in an adult male. Renal hypoplasia is a congenital abnormality in which one or both of the kidneys are smaller than normal, [ 5] resulting in a reduced nephron number [ 1] but with normal morphology. [ 4]
Triiodothyronine, also known as T 3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. [1] Production of T 3 and its prohormone thyroxine (T 4) is activated by thyroid-stimulating hormone (TSH
