Question

S. Which kidney is associated with a longer renal vein and which kidney is associated with a longer renal artery? Longer renal vein: Longer renal artery: Name the capillary that enters the glomerular capsule and name the capillary that exits the glomerular 6. capsule. Enters: Exits: 7. What is the muscular portion of the urinary bladder called? When erythrocytes enter into the glomerular capillaries they will then (under normal circumstances) enter the 8. (Circle your answer). Efferent arteriole Afferent arteriole Proximal convoluted tubule 9. (Research) The kidneys are retroperitoneal. What does retroperitoneal mean? (Research) What do the following terms mean in reference to this unit? a. Urolithasis- 10. b. Lithotripsy c. Calculi

Explanation / Answer

5.

Longer renal vein: Left renal vein ( because inf vena cava lies right side of midline).

Longer Artery: Right renal artery ( because the abdominal aortal lies left to the midline)

6.

Enters: Afferent arteriole.

Exits: Efferent arteriole.

7. Detrusor.

8. Efferent arteriole.

9.

Kidney is a retroperitoneal structure.

Retroperitoneal mean outside and posterior to peritoneal sac. Anterior surface of kidney is covered by the outer layer(parietal layer) of peritoneum which make the kidney as retroperitoneal structure. Retroperitoneal structures are not suspended by mesentry. This means theat the kidney's anterior surface is covered by parietal layer of peritoneum and it is an abdomina organ but outside of peritoneal cavity.

10.

Urolithiasis:Thisis define as the process of stone formation in nay structure of urinary system( ie kidney, bladder, ureter). Causes are: Decreased urine volume due to dehydration which force less excretion of products like calcium, oxalate, urate, cystine, xanthine, and phosphate or it may be due to excess formation of thise stone forming components. It may also cause due to medication which cause hyperuricaemia. As a result these components deposited and form stone in the collective system of renal system( ie pelvis of kidney, ureter, bladder etc). This condition is extremely painfull. Treatment: Medication like xanthine oxidase inhibitors, urine alkaliser are used to medically treat the condition. If medical treatment fails, then minimal invasive surgery like lithotrypsy is tried. If the stones are large enough, invasive surgery is done to remove stones from retroperitoneal approach.

Lithotrypsy: This is a minimal-invasive day care surgical procedure to remove stones from renal system( ie kidney, ureter, urinary bladder). In this procedure shock wave is utilized to break bigger stones into smaller pieces and the the patient is asked to take lots of fluid to pass out these samller pieces of stone with urine.

Calculi (Renal): In this context it is renal calculi. Renal calculi may be of various types depending the composition of the calculi.Types: Calcium oxalate stone, Uric acid stone, Struvite associated with urinary tract infection, Cysteine stone. Cause: dehydration, gout patient, increased dietary intake of animal proteins, apple juice, grapes juice, fructose, eating oxalate rich food( ie peanuts, potato chips, beets, spinach, chocolates), frequent urinary tract infection, Inflammatory bowel sysdrome, Hyperparathyroidism, Gastric bypass surgery, Obesity.
