Q

An ultrasound or — can detect differing sizes of kidneys or ureters and can differentiate between solid or cystic kidney masses.

A

magnetic resonance imaging (MRI)

18
Q

involves passing a thin biopsy needle into the kidney through the skin over the kidney.

A

Renal biopsy

19
Q

When the bladder first forms in utero, it is joined to the umbilicus by a narrow tube, the —.

A

PATENT URACHUS

20
Q

Midline closure defect that occurs during the 10th week of pregnancy.
Bladder lies exposed on the anterior abdominal wall.

A

EXSTROPHY OF THE BLADDER

21
Q

is a urethral defect in which the urethral opening is not at the end of the penis but on the ventral (lower) aspect of the penis.

A

Hypospadias (ventral aspect)-

22
Q
  • newborn surgical procedure in which the urethra is extended to a normal position-may initially be performed to establish better urinary function
A

Meatotomy

23
Q

more often in females than in males; urethra is shorter in girls and close to vaginal and anus
Most often as an ascending infection from the perineum and are gram-negative rods such as E. coli.

A

URINARY TRACT INFECTION

24
Q

refers to lower UTI seen in young women shortly after they initiate a first sexual relationship. Such infections occur in connection with the local irritation and inflammation caused by initial coitus

A

Honeymoon cystitis

25
Q

refers to retrograde flow of urine from the bladder into the ureters.
Valves that guard the entrance from the bladder to the ureter are defective, bladder pressure that is stronger than usual, or ureters that are implanted at abnormal sites or angles.

A

Vesicoureteral reflux

26
Q

is enlargement of the pelvis of the kidney with urine as a result of back-pressure in the ureter.
The back-pressure is generally caused by obstruction, either of the ureter or of the point where the ureter joins the bladder, as with vesicoureteral reflux.

A

Hydronephrosis

27
Q

is involuntary passage of urine past the age when a child should be expected to have attained bladder control.

A

Enuresis

28
Q

Enuresis may be nocturnal

A

occurs only at night

29
Q

diurnal

A

occurs during the day

30
Q

A few children will spill albumin into the urine when they stand upright for an extended period (postural proteinuria, also called pastoral albuminuria).

A

POSTURAL (ORTHOSTATIC) PROTEINURIA

31
Q

means lack of growth (literally, lack of a beginning) or that no organ formed in utero.
absence of Kidneys in a newborn is suggested when the volume of amniotic fluid on ultrasound or at birth Is less than normal (oligohydramnios).

A

KIDNEY AGENESIS

32
Q

means reduced growth.
Hypoplastic kidneys contain fewer lobes than normal kidneys and are small and underdeveloped.
The child with hypoplastic kidneys, in addition to having poor kidney function, may develop hypertension from stenosis of the renal arteries.

A

RENAL HYPOPLASIA

33
Q

is severe urinary tract dilation that develops as early as intrauterine life from an unknown cause.
Occurring mainly in boys, the severe dilation causes back pressure and destruction of kidneys.

A

Prune belly syndrome

34
Q

, Inflammation of the glomeruli or the kidney, may occur as a separate entity but usually occurs as an immune complex disease after infection with nephritogenic streptococci (most commonly subtypes of group A beta-hemolytic streptococci).

A

ACUTE POSTSTREPTOCOCCAL GLOMERULONEPHRITIS

35
Q

Although — occasionally follows acute glomerulonephritis or nephritic syndrome, it also occurs as a primary disease (or after acute glomerulonephritis that was clinically so mild it was undiagnosed)

A

chronic glomerulonephritis

36
Q

altered glomerular. permeability due to fusion of the glomerular membrane surfaces, causes abnormal loss of protein in urine.

A

NEPHROTIC SYNDROME

37
Q

Approximately one quarter of the children who develop this type of purpura develop renal disease as a secondary complication.

A

HENOCH-SCHONLEIN SYNDROME NEPHRTIS

38
Q

an autoimmune disease in which autoantibodles and antigens cause deposits of complement in the kidney glomerulus

A

SYSTEMIC LUPUS ERYTHEMATOSUS

39
Q

With —, the lining of glomerular arterioles becomes inflamed, swollen, and occluded with particles of platelets and fibrin.

A

HEMOLYTC-REMIC SYNDROME

40
Q

occurs in either an acute or chronic form.
The acute form most often occurs because of a sudden body insult, such as severe dehydration.
The chronic form results from extensive kidney disease, such as hemolytic-uremic syndrome or glomerulonephritis

A

ACUTE RENAL FAILURE

41
Q

results from developmental abnormalities, when acute failure becomes long term, or when chronic kidney disease has caused extensive nephron destruction.

A

CHRONIC KIDNEY DISEASE

42
Q

Kidney Transplantation

A

The ultimate possibility for prolonging the life of children with renal failure is kidney transplantation.
With complete renal failure, children who have extensive hypertension may have their damaged kidneys removed and may be placed on hemodialysis to await kidney transplantation.
