24
Q

Urinary Tract Infection (UTI)

A

The most common of all bacterial infections, a UTI is an infection in the urinary tract usually caused by a gram-negative bacillus, which invaded by an ascending route through the urethra to the bladder to the kidney.

25
Q

Vesicoureteral Reflux

A

The backward flow of urine out of the bladder and into the ureters.

26
Q 
Vesicoureteral reflux refers to the backward flow of urine into the:
A: Bladder
B: Major calyx
C: Ureters
D: Urethra 
E: Any of the above
A

C: Ureters

27
Q

Bladder Carcinoma: Additive/Subtractive/Both/Neither

28
Q

Neurogenic Bladder

A

A bladder dysfunction caused by interference with the nerve impulses concerned with urination.

29
Q

Bladder diverticula

A

A pouch in the wall of the urinary bladder.

30
Q

Bladder trabeculae

A

Roughening of the normally smooth bladder wall.

31
Q

Bright disease

A

An inflammatory reaction of the renal parenchyma caused by an antigen antibody reaction in the glomeruli.

32
Q

What condition can make the kidneys appear smaller than normal?

A

Atrophy following obstruction. , chronic pyelonephritis, and hypoplasia.

33
Q

Pyuria

A

The presence of pus in urine, created by its drainage from renal abscesses into the kidney’s collecting tubules

34
Q

Radiofrequency Ablations

A

A process that uses radiofrequency waves to remove tissue

35
Q

Renal Agenesis

A

The absence of the kidney on one side, with an unusually large kidney on the other side

36
Q

Congenital Anomalies: Additive/ Subtractive/Neither/Both

37
Q

Lower Urinary Tract Anomalies: Additive/ Subtractive/ Both/Neither

38
Q

Ureteral Stents

A

Are placed surgically or via cystoscopy, with upper portion of the stent in the renal pelvis and the lower portion within the urinary bladder. Stent maintains patency of the diseased ureter and enables urine to flow normally.

39
Q

Ureterocele

A

Is a cystlike dilation of a ureter near its opening into the bladder.

40
Q

polycystic kidney disease

A

A familial kidney disorder in which innumerable tiny cysts that are present congenitally gradually enlarge during aging to compress and eventually destroy normal tissues

41
Q

pyelonephritis

A

Bacterial infection of the kidney and its pelvis

42
Q

Statements true about neoplastic diseases of the urinary systems.

A
  1. Chronic inflammation from obstruction may result in adenocarcinoma.
  2. Early excision of nephroblastoma has shown very high cure rate.
43
Q 
Horseshoe kidney is an anomaly

Q

Hydronephrosis: Additive/ subtractive/both/neither

45
Q

Renal Cyst: additive/Subtractive/both/neither

A

subtractive

46
Q

Staghorn Calculus

A

A large renal calculus that assumes the shape of the pelvicalyceal junction, resembling the horn of a stag

A

Additive (If reflux is present)

50
Q

Nephroptosis

A

Prolapse of kidney

51
Q

Nephrosclerosis

A

Intimal thickening of predominately the small vessels of the kidney as a result of reduced blood flow through arteriosclerosis renal vasculature

52
Q

Nephrostomy tube

A

A tube inserted through the abdominal wall into the renal pelvis to drain urine

53
Q 
Significant dilation of the renal pelvis and calves as a result of an obstruction from a stone is characteristic of:
A) hydronephrosis
B) renal failure
