GU system Flashcards
what does PKD stand for
polycystic kidney disease
what is a serious condition characterized by an increasing number of cyst formations in the kidneys
PKD
by the age of 60, what % of PKD patient will have developed end stage renal failure
50%
how does PKD appear
numerous cysts throughout both kidneys
in advanced stages of PKD, it can affect other organs - especially which one
liver
what is also known as renal calculi and urolithiasis
renal stones
what do those terms describe
condition of stone formation in urinary tract
where do renal stones originate in
collecting system of kidneys
where can stones move into
ureters and bladder
what are the different causes of renal stones
dehydration, low fluid intake, high caffeine intake, recurrent UTIs and several metabolic abnormalities
what can renal calculi lodge in ureters cause
obstruction of urine flow
what is a result of obstruction of urine flow
hydronephrosis
what is hydronephrosis
condition of swelling of kidneys and collection system as a result of urine backup
what is often visible even when stone is too small to be imaged
hydronephrosis
what is RCC
renal cell carcinoma
what is most common malignant neoplasm of kidneys
renal cell carinoma
what does RCC commonly affect
all components of kidneys (cortex, medulla, and collecting system)
what are the features RCC generally demonstrates
general kidney enlargement, large lesions show areas of necrosis and 30% of RCC show calcification
RCC can be unifocal or multifocal
true
what is a malignant pediatric renal tumor
wilm’s tumor
wilm’s tumor accounts for what % of all peds renal neoplasms
85%
what % of wilm’s tumors are diagnosed before the age of 5
80%
how is wilm’s tumor visualized
large mass completely replacing kidney and filling one side of abdominal cavity
wilm’s condition is usually what
unilateral
what is a common consequence of trauma to abdomen
kidney laceration
what is fractured followed by hemorrhage and sometimes infarct in kidney laceration
renal parenchyma
what does imaging show when talking about lacerations
not laceration itself, but effects.
they are:
atypical/non uniform contrast perfusion through organ, limited or absence of contrast, contrast extravasation in or around organ, and hematoma in area of organ
what is a congenital condition in which the kidneys are fused together at the upper or lower poles
horseshoe kidney
the horseshoe condition renders the kidneys especially susceptible to what
trauma, renal stone, and renal cancer
how do kidneys appear in horseshoe kidney
elongation in transverse plane and medial fusion
what is most common bladder cancer
transitional cell carcinoma (TCC)
what is most common tumor of entire urinary tract
TCC
how do bladder TCCs most often appear
as asymmetric wall thickening or a mass protruding from the bladder wall into the body of bladder
occasionally, bladder TCC can do what
protrude out of bladder wall and invade surrounding tissues
what can adrenal gland host
benign, malignant and cystic lesions
what can malignant lesions of adrenals be
both primary and secondary neoplasms
what are at least 90% of uterine malignancies classified as
endometrial cancer
what is most common gynecological malignancy
endometrial cancer
how can endometrial cancer appear as
abnormal endometrial wall thickening in early stages, in later stages as large, necrotic, loculated mass filling in pelvis and even abd
what is a benign lesion of uterus
uterina leiomyoma
what else is a uterus lesion known as
uterine fibroids
what is a solid soft tissue tumor
uterina leiomyoma
uterine fibroids occur in what % of women of reproductive age
20-30%
how do fibroids appear
greatly in size and distribution throughout uterus
how do fibroids also appear
as well defined, round, soft tissue masses
what is common with fibroids
calcification
how can ovarian tumors be
benign, malignant and solid or cystic
what is a distinguishing factor of ovarian tumors
ovarian enlargement
what are all signals of abnormal ovarian growth
ovarian wall thickening, cystic changes, and calcifications
what are commonly encountered in sectional imaging
ovarian cysts
how do ovarian cysts present
as small to large fluid collections extending from the ovaries
a small cyst (<25mm) should be considered what in women of reproductive age
normal ovarian follicle
a simple benign cyst is also completely what
homogenous and without loculations
what is most common cancer in men
prostate cancer
what is 2nd most common cause of death in men
prostate cancer
what is prostate cancer sometimes referred to as
prostatic carcinoma or prostatic adenocarcinoma
where does prostate cancer gerenally being
in posterior portion (peripheral zone) near rectum
how is prostate cancer apparent in sectional imaging
general prostate enlargement, asymmetry, and lymphadenopathy
advanced prostatic cancer shows metastasis to what
the bones
what is often necessary to distinguish between prostate cancer and benign prostate hypertrophy
biopsy
what is BPH
benign prostate hypertrophy
what is extremely common in elderly men
BPH
what can BPH result in
urine outflow obstructions
by the age of what, 90% of men have some degree of BPH
90
BPH appears similar to prostatic cancer expect what
there is no lymph involvement, no focal mass lesion, and enlargement is generally more symmetrical
