PUVs Glossary

Anterior Urethral Valves - Similar to PUVs, although occurring 7-8 times less frequently. A congenital blockage of tissue in the anterior urethra

Bladder - A hollow, muscular organ that stores urine.

Bladder Augmentation - A surgery to enlarge the bladder.

BUN (Blood Urea Nitrogen) - A blood test to measure of the amount of nitrogen in the blood in the form of urea, and a measurement of renal function.

Clean intermittent catheterization (CIC) - Regular catheterization (insertion of a small tube into the urethra) of the bladder in order to empty it completely.

Congenital - A condition or disease that is present at birth.

Creatinine - A blood test to help determine kidney function.

Cystoscopy - The use of a scope to examine the bladder.

Diabetes Insipidus (Nephrogenic) - A defect in the parts of the kidneys that reabsorb water back into the bloodstream that causes the kidneys to be unable to conserve water.

Hydronephrosis - Swelling of the kidneys caused by an obstruction or refluxing of urine flow.

Kidneys - A pair of organs that filter the blood of the waste, unused minerals, and water that make up urine.

Mag3 (DTPA) Scan - This renal scan is done to look at the blood flow to the kidneys and how well each kidney works to produce urine. It can also show if there is any narrowing of the renal artery and if there are any obstructions. Mag3/DTPA is the name of the chemical used in the scan.

Mitrofanoff - A surgically placed tunnel (usually made from the appendix) from the bladder to the outside through which you can catheterize.

Megaureter - A ureter that is enlarged because of a problem in the urinary tract.

Nephrectomy - Surgical removal of the kidney.

NG tube (nasogastric tube) - a feeding tube that goes into the body through the nose and down into the stomach.

Non-neurogenic neurogenic bladder - A bladder condition where the bladder is emptied infrequently due to voiding problems where there is no neurogenic cause.

Obstructive uropathy - A condition in which a blockage in the urinary tract doesn’t allow urine to flow properly.

Oligohydramnios - Having too little amniotic fluid

Posterior Urethral Valves - A congenital blockage of tissue in the posterior of the urethra.

Potter's Syndrome (Bilateral Renal Agenesis) - A condition in which the kidneys fail to develop.

Prune Belly Syndrome (Eagle-Barrett syndrome) - A congenital defect that includes three main charecteristics: Abdominal wall muscles are deficient or absent, Urinary tract anomalies, Undescended testicles

Pyelostomy - Surgical opening into the kidney from the outside of the body.

Renal Dysplasia (multicystic dysplastic kidney) - A condition where the kidneys do not develop normally.

Ultrasound - The use of sound waves to view inside the body

Ureters - A pair of tubes that carry urine from the kidneys to the bladder.

Ureteropelvic junction (UPJ) obstruction - A blockage where the kidney connects to the ureter.

Ureterostomy - A surgical opening from the ureter to the outside of the body.

Urethra - Tube that carries urine from the bladder out of the body.

Urinalysis - A variety of tests on urine.

Urodynamics - A study that determines how the bladder and urethra are performing their job of storing and releasing urine. Several tests are included in this study including Uroflowmetry (Measurement of Urine Speed and Volume), Measurement of Postvoid Residual, Cystometry (Measurement of Bladder Pressure), and Video Urodynamics and sometimes others.

Valve Ablation - The surgical removal of the valves.

VATERS/VACTERL - A syndrome in which a child may have abnormalities in the following areas: Vertebrae, Anus, Trachea, Esophagus, and Renal. There can also be cardic and limb conditions which changes the acrynym to VACTERL.

VCUG (Voiding Cystourethrogram) - A special xray of the urinary track, using contrast, of the urinary track to look for vesicoureteral reflux and evaluate the bladder's size, shape, and capacity.

Vesicoureteral reflux - A condition in which urine flows backward (refluxes) from the bladder into one or both ureters and possibly the kidneys.

Vesicostomy - A surgical opening from the bladder to the outside of the body.
