  Kidney - Wikipedia, the free encyclopedia
The outermost portion of the kidney is called the renal cortex, deep to which lies the renal medulla.
The segment that drains glomerular filtrate from the Bowman's capsule is the proximal convoluted tubule.
Renal functions include the excretion of waste material from the bloodstream, secretion of hormones - particularly erythropoietin and renin and maintaining serum electrolyte, acid-base levels and osmolality.

 renal agenesis
Renal agenesis and hypoplastic lung syndrome are congenital malformations of the neonates involving the kidneys and the lungs respectively i.e.
During prenatal life renal agenesis could be diagnosed with ultrasound examination both by the observation of oligohydramnios i.e.
With regards to bilateral renal agenesis, the fetus is usually stillbirth in more than 40% of cases while the majority of infants born alive usually die within 4 hours of life.

 Syllabus on Geriatric Anesthesiology
Renal dysfunction remains a serious complication during the perioperative period and is most likely to occur in critically ill patients undergoing major surgery.
Perioperative renal failure following trauma and thoracic or cardiovascular surgery carries a reported incidence of 0.1% to 50%, depending on the population analyzed and the methods used to define renal failure, and is associated with a reported mortality of 20 percent to 90 percent.
The precise mechanisms heralding the transition from compensated preserved renal function to uncompensated renal failure during the perioperative period remain poorly understood, in part because the methods used to assess renal function are insensitive and nonspecific.

 MedlinePlus Medical Encyclopedia: Acute kidney failure
Acute renal failure is sudden loss of the ability of the kidneys to excrete wastes, concentrate urine, and conserve electrolytes.
Renal angiography (renal arteriography) may be used to diagnose causes within the blood vessels of the kidney.
Although acute renal failure is potentially life-threatening and may require intensive treatment, it usually reverses within several weeks to a few months after the underlying cause has been treated.

 Renal Cystic Disease
The hallmark of renal dysplasia is the presence of "primitive ducts" lined by cuboidal to columnar epithelium and surrounded by a collagenous stroma.
Multicystic renal dysplasia is often the only finding, but it may occur in combination with other anomalies and be part of a syndrome (e.g., Meckel-Gruber syndrome), in which case the recurrence risk will be defined by the syndrome.
Renal failure is unlikely to occur, but may result from severe pyelonephritis.

Elevated PTH levels are sustained by decreased renal degradation and reduced negative feedback suppression by vitamin D. PTH acts to raise calcium by osteoclast activation, stimulation of intestinal absorption and various renal effects.
The clinical presentation is influenced by the patient's age at onset of renal failure, the etiology of the renal disease, dietary content (protein, phosphate and calcium) and treatment modalities.

Renal ultrasonography or helical CT may distinguish pyonephrosis from simple hydronephrosis by demonstrating a fluid-fluid level in the renal pelvis (urine on top of purulent debris).
Renal calyces, pelvis, and proximal ureter can be examined and stones extracted with or without prior fragmentation.
Infected hydronephrosis is the most deadly complication because the presence of infection adjacent to the highly vascular renal parenchyma places the patient at risk for rapidly progressive sepsis and death.
