Kidney Kidney The kidneys are two bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The nephron is the structural and functional unit of the kidney. Each adult kidney contains around 1 million nephrons. The nephron utilizes four processes to alter the blood plasma which flows to it: filtration, reabsorption, secretion, and excretion. The
Bladder augmentation cancers of the intestinal tissue within the bladder. This surgery has been popular since the 1980s and 90s. Bladder augmentation Bladder augmentation is a surgical alteration of the urinary bladder. It involves removing strips of tissue from the intestinal tract and adding this to the tissue of the bladder. This has two intended results: increased bladder volume; and a reduced percentage of the bladder involved in contraction, that in turn results in lower internal pressures in the bladder during urination.Risks of bladder augmentation include incomplete voiding of the bladder post-surgery (resulting in the patient having to undergo intermittent catheterisation or
