  Renal capsule - Wikipedia, the free encyclopedia
Transverse section, showing the relations of the capsule of the kidney.
The renal capsule (also known as Gerota's fascia) is a tough fibrous layer surrounding the kidney and covered in a thick layer of perinephric adipose tissue.

 Kidney - Wikipedia, the free encyclopedia
The outer portion of the kidney is called the renal cortex, which sits directly beneath the kidney's loose connective tissue/fibrous capsule.
Due to the polar alignment of cells in the renal epithelia NHE3 and the H-ATPase are exposed to the lumen (which is essentially outside the body), on the apical side of the cells, and are responsible for excreting hydrogen ions (or protons).
Pyelonephritis is infection of the kidneys and is frequently caused by complication of a urinary tract infection.

 Flank Pain
Flank pain caused by renal inflammation generally is not as sudden in onset or as severe as pain caused by acute ureteral obstruction.
Renal inflammation usually produces localized pain and is associated with other manifestations of infection such as fever, leukocytosis, and bacteriuria.
Progression of irreversible renal damage resulting from ureteral obstruction is related to many factors including the duration of obstruction, degree of obstruction, presence or absence of infection above the obstruction, preexisting renal function, status of the contralateral kidney, and age of the patient.

 eMedicine - Nephrolithiasis: Acute Renal Colic : Article by Stephen W Leslie, MD, FACS
Renal tomography requires moving the radiograph projector and film in such a way that a zone of photographic clarity is positioned at the stationary focus point of the radiograph beam.
Plain renal tomography is most useful when checking for small stones that might be present in the kidney before starting a preventive therapy plan or when differentiating intrarenal calcifications that are likely to be stones from extrarenal opacities that are clearly not renal calculi.
The noncontrast or renal colic-type CT scan is good for the initial diagnosis of a stone, especially in unusual or atypical cases or when patients are unable to tolerate intravenous contrast because of allergy or azotemia.

 Renal System Anatomy Including Kidneys - nephrologychannel
They are protected by three layers of connective tissue: the renal fascia (fibrous membrane) surrounds the kidney and binds the organ to the abdominal wall; the adipose capsule (layer of fat) cushions the kidney; and the renal capsule (fibrous sac) surrounds the kidney and protects it from trauma and infection.
The renal artery enters the kidney and the renal vein emerges from the kidney at an indentation in the middle of the organ called the hilum.
Urine formation occurs in the renal tubules, which travel from the outer tissue of the kidney (called the cortex), to the inner tissue (called the medulla), and return to the cortex.
