Urinary System Flashcards
-Bacterial infection of the calyces and renal pelvis, usually due to stagnation or obstruction to urine flow in the urinary tract
-Symptoms include fever, flank pain, and general malaise; pyuria (pus i.e. white blood cells) is demonstrated in a urinalysis
medullary sponge kidney
pyelonephritis
bright disease
polycystic kidney disease
pyelonephritis
bright disease (Glomerulonephritis)- An antigen–antibody reaction in the glomeruli causes an inflammatory reaction of the renal parenchyma
polycystic kidney disease- Innumerable tiny, nonfunctioning cysts replace the renal collecting tubules within the nephron unit.
This Neoplastic Disease is usually asymptomatic and affects the lower pole of the kidney. The treatment if needed is an aspiration of the contents.
renal cysts
nephrosclerosis
renal cell carcinoma
hydronephrosis
renal cysts
nephrosclerosis- thickening of kidney vessels
renal cell carcinoma- A malignant tumor arising from renal tubular epithelium in the cortex of the kidney
hydronephrosis- obstructive disease of the urinary system that causes dilation of the renal pelvis and calyces with urine
A malignant tumor arising from renal tubular epithelium in the cortex of the kidney. Symptoms include hematuria with possible flank pain, fever, or a palpable mass.
renal cell carcinoma (RCC)
nephroblastoma
bladder carcinoma
Wilm’s tumor
renal cell carcinoma (RCC)
nephroblastoma (wilm’s tumor)- A malignant tumor of the kidney generally occurring
in children under 5 years of age
Hematuria is:
blood in urine
pus in urine
excessive amounts of urine
urinary tract infection
blood in urine
-In this fusion anomaly, one kidney lies across the midline and is fused with the other kidney
-Urine drainage may be impaired by malposition of the affected ureter within the renal pelvis
nephroptosis
horseshoe kidney
crossed ectopy
hyperplasia
crossed ectopy
nephroptosis- kidney prolapse
horseshoe kidney- condition in which the lower poles of the kidney are joined across midline by a band of soft tissues, resulting in a rotation anomaly on one or both sides
hyperplasia- overdevelopment of a kidney
-Placed within the urinary bladder using sterile technique, this is the most common indwelling urinary catheter
-The catheter is usually connected to a bag that collects urine as it flows through the catheter to the outside of the body
-At all times the urine collection bag must be placed at a level lower than the patient’s bladder to prevent reflux of urine back into the bladder that could lead to a urinary tract infection (UTI)
-These catheters must be placed prior to performing cystography or cystourethrography
nephrostomy tube
ureteral stent
suprapubic catheter
Foley catheter
Foley catheter
nephrostomy tube- Connects the renal pelvis to the outside of the body. Provides drainage of an obstructed kidney or allow for retrieval of a calculus with a basket catheter
ureteral stent- placed in cases of ureteral obstruction. Placed surgically or via cystoscopy, with the upper portion of the stent in the renal pelvis and the lower portion within the urinary bladder. Each end of the stent forms a loop, commonly called a “pigtail,” to help secure its placement. The stent maintains patency (open) of the diseased ureter and enables urine to flow normally.
suprapubic catheter- may be used instead of a Foley catheter. Involves a needle puncture through the skin and into the bladder, just above the pubic symphysis, to feed a guidewire and then pull away sheath through which the catheter is introduced. Used for individuals such as those with quadriplegia (paralyzed) who require long-term catheterization. May also be placed in a person who requires urinary catheterization but has urethral trauma or disease, such as a stricture, that prevents traditional urinary catheter insertion.
-Radiographically, this cyst-like dilation of a ureter nears its opening in the bladder presents in the bladder as a “cobra head” appearance
-These result due to congenital stenosis (narrowing) of the ureteral orifice
ureteral diverticula
aplasia
ureterocele
medullary sponge kidney
ureterocele
ureteral diverticula- Congenital anomaly and represents a dilated, branched ureteric remnant.
Renal Agenesis (Aplasia)- Congenital absence of a kidney
-The imaging procedure that is used to demonstrate reflux and grade its severity
-Normally iodinated water-soluble contrast media is injected into the bladder via a urinary catheter that is inserted through the urethra
renal angiography
cystography
intravenous urogram (IVU)
retrograde pyelography
cystography
intravenous urogram (IVU)- involves injecting a contrast dye into your arm, then taking a series of X-ray images at timed intervals as the dye travels through your kidneys, ureters, and into your bladder
retrograde pyelography- Placement of a catheter into the ureteric orifice in a retrograde fashion. The contrast agent is injected through the ureter into the affected kidney, opposite to the normal direction of urine flow.
