THE RENAL SYSTEM

• STRUCTURES:– KIDNEYS

• RETROPERITONEAL• RENAL ARTERY & VEIN• NEPHRON

– URETER– URINARY BLADDER– URETHRA

Here is a normal adult kidney. The capsule has been removed and a pattern of fetal lobulations still persists, as it sometimes does. The hilum at the mid left contains some adipose tissue. At the lower right is a smooth-surfaced, small, clear fluid-filled simple renal cyst. Such cysts occur either singly or scattered around the renal parenchyma and are not uncommon in adults.

In cross section, this normal adult kidney demonstrates the lighter outer cortex and the darker medulla, with the renal pyramids into which the collecting ducts coalesce and drain into the calyces and central pelvis.

THE RENAL SYSTEM

• 4 MAIN FUNCTIONS OF THE KIDNEYS:

– EXCRETION OF WASTE PRODUCTS• FILTRATION• TUBULAR REABSORPTION• TUBULAR SECRETION

– REGULATION OF FLUID & ELECTROLYTES– BLOOD PRESSURE REGULATION– ERYTHROPOEITIN SECRETION

THE RENAL SYSTEM

PHYSIOLOGY:• RENIN-ANGIOTENSIN

• ERYTHROPOEITIN

• PROSTAGLANDIN

RELEASED BY CELLS NEAR THE GLOMERULUS WHEN GFR IS LOW OR WHEN SYMPA-NS IS STIMULATED

RELEASED IN RESPONSE TO HYPOXEMIA

•IS RELEASED BY RENAL MEDULLA; VASODILATOR; REGULATE RENAL BLOOD FLOW

THE RENAL SYSTEM

PHYSIOLOGY:• METABOLISM OF VIT D – FOR CALCIUM

METABOLISM

• DEGRADATION OF INSULIN• URGE TO VOID : 200-300 ml OF URINE

• BLADDER DISTENTION: 400 ml• PARASYMPA-NS : DESIRE TO VOID

• SYMPA-NS: MUSCLE RELAXATION & ELIMINATION

Double ureters are seen exiting from each kidney and extending to the bladder that has been opened. A small segment of aorta is seen between the normal, smooth-surfaced kidneys. A partial or complete duplication of one or both ureters occurs in about 1 in 150 persons. There is a potential for obstructive problems due to the abnormal flow of urine and the entrance of two ureters into the bladder in close proximity, but most of the time this is an incidental finding

UROLITHIASIS

There was a large renal calculus (stone) that obstructed the calyces of the lower pole of this kidney, leading to a focal hydronephrosis (dilation of the collecting system). The stasis from the obstruction and dilation led to infection.

The infection with inflammation is characterized by the pale yellowish-tan areas next to the dilated calyces with hyperemic mucosal surfaces. The upper pole is normal and shows good corticomedullary demarcations.

Sometimes a very large calculus nearly fills the calyceal system, with extensions into calyces that give the appearance of a stag's (deer) horns. Hence, the name "staghorn calculus". Seen here is a horn-like stone extending into a

dilated calyx, with nearly unrecognizable overlying renal cortex from severe hydronephrosis and pyelonephritis. Nephrectomy may be performed because the kidney is non-functional and serves only as a source for infection.
