Kidney

What is Kidney?

The kidneys are bean-shaped organs that serve several essential regulatory roles in vertebrates. They remove excess organic molecules from the blood, and it is by this action that their best-known function is performed: the removal of waste products of metabolism. Kidneys are essential to the urinary system and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and regulation of blood pressure (via maintaining the salt and water balance). They serve the body as a natural filter of the blood, and remove water-soluble wastes which are diverted to the bladder. In producing urine, the kidneys excrete wastes such as urea and ammonium. They are also responsible for the reabsorption of water, glucose, and amino acids. The kidneys also produce hormones including calcitriol, erythropoietin, and the enzyme renin, the last of which indirectly acts on the kidney in negative feedback.

Located at the rear of the abdominal cavity in the retroperitoneal space, the kidneys receive blood from the paired renal arteries, and drain into the paired renal veins. Each kidney excretes urine into a ureter which empties into the bladder.

Renal physiology is the study of kidney function, while nephrology is the medical specialty concerned with kidney diseases. Diseases of the kidney are diverse, but individuals with kidney disease frequently display characteristic clinical features. Common clinical conditions involving the kidney include the nephritic and nephrotic syndromes, renal cysts, acute kidney injury, chronic kidney disease, urinary tract infection, nephrolithiasis, and urinary tract obstruction. Various cancers of the kidney exist. The most common adult renal cancer is renal cell carcinoma. Cancers, cysts, and some other renal conditions can be managed with removal of the kidney. This is known as nephrectomy. When renal function, measured by the glomerular filtration rate, is persistently poor, dialysis and kidney transplantation may be treatment options. Although they are not normally harmful, kidney stone can be painful.

For the past 8 months, I have had persistent flank pain swelling on my left side. To me, it feels like a sharp rock is almost stuck just under my rib cage, but to the touch [externally] it feels like a firm sponge? That's the best way I can describe it... All x-rays came back negative for kidney stones, and blood tests were all normal. A catheter sample came back positive for trace amounts of blood, but kidney function was otherwise normal. Ultrasound came back normal; kidneys appeared to be healthy. The CT scan came back otherwise normal, except for some leakage from the lymph nodes. I am not at all familiar with the lymphatic system and it's problems. I have been to see 3 general physicians, a urologist, and a general surgeon, and they all have no idea what could be the problem, and simply keep sending me back for more urine and blood tests. Which all continue to be normal, other than trace amounts of blood in the urine. Any ideas as to what may be causing my suffering would be greatly appreciated.
