Exstrophy of the bladder – the bladder is essentially inside out and exposed on the outside of the abdomen. Because the bladder and other structures are exposed to the outside of the body, urine constantly trickles onto the skin causing local irritation.
Hematuria: the presence of blood in urine. This may be microscopic or gross (i.e. urine is pink or red).
Hernia: a communication between the abdomen and scrotum that enables intestine or other abdominal structures to track into the scrotum. See image below:
Horseshoe kidney – as the kidneys of the fetus arise from the pelvic area they abnormally fuse together at the lower end or base. By fusing, they form a “U” shape, which gives it the name “horseshoe.”
Hydrocele: Fluid around the testicle(s) in the scrotum. This may be due to a communication between the abdominal cavity and the scrotum which may cause fluid to accumulate in the scrotum. See image below:

Many different pathologic and physiologic processes may be associated with hydronephrosis. See image below:
Hypospadias: This is the condition in which the urine hole (meatus) is located on the underside of the penis. It may be located toward the tip (distal) or toward the scrotum (proximal). See image below:
Inguinal hernia – when a section of intestine protrudes through a weakness in the abdominal muscles in the groin area.
Intravenous pyelogram (IVP ) – a series of x-rays of the kidney, ureters, and bladder with the injection of a contrast dye into the vein – to detect tumors, abnormalities, kidney stones, or any obstructions, and to assess renal blood flow.
Kidney stone – a solid piece of material that forms from crystallization of excreted substances in the urine.
Kidney transplantation – a procedure that places a healthy kidney from one person into a recipient’s body.
Kidneys – a pair of bean-shaped organs located below the ribs toward the middle of the back.

Meatal Stenosis: narrowing of the meatus, which may cause pain or difficulty in directing the urine stream.
Meatotomy: a minor procedure performed to correct meatal stenosis.
Meatus: urethral opening or pee hole.”
megaureter – an expanded or widened ureter that does not function normally. The size of a megaureter is usually greater than 7 millimeters in diameter.
Micropenis – a normally structured penis that is below the normal size range for an infant.
MRI: Magnetic Resonance Imaging. An imaging technique that entails no radiation exposure. However, sedation may be necessary for young children. See image below:
MRU: Magnetic Resonance Urogram. See MRI; Specific type of MRI which gives urologist anatomic detail about the urinary tract. Sedation may be necessary for young children, but there is no radiation exposure. See image below:
Multicystic dysplastic kidney (MCDK): Condition in which entire kidney consists of cysts. These kidneys have no function and should shrink to a minimal size early in childhood.
Neurogenic bladder: Condition in which the nerves leading to, or within the urinary bladder cause the organ to malfunction.
Nephrectomy: Surgical removal of a kidney.
Nephrostomy tube: Also called percutaneous nephrostomy tube. Small tube placed into the kidney through the back in order to drain urine.
Orchidopexy: surgical procedure that relocates testicle from groin or abdomen into the scrotum.
Orchiectomy: Surgical removal of a testicle
Paraphimosis: This occurs after the foreskin has been retracted, but cannot be pulled back over the head of the penis (glans penis) to cover this structure. This is a painful condition and requires immediate attention.
Phimosis: This is when the penile foreskin cannot be retracted (pulled back) adequately in a boy. Some degree of phimosis may be normal, especially in young boys.
Posterior urethral valves: a condition in which leaflets of urethral tissue cause a blockage in the urethra. This condition requires surgical correction early in life. See image below:
Priapism: Sustained and usually painful erection lasting more than 6 hours. In children, sickle cell disease is the most common cause of priapism.
proteinuria – large amounts of protein in the urine.
Prune belly syndrome – a triad of symptoms that include multiple urinary tract abnormalities. The common abnormalities include an absence of abdominal muscles, undescended testes, and abnormalities of the upper urinary tract.

Testicular torsion: (“torsion”) This is the condition in which the blood supply to the testicle twists, usually resulting in acute and severe pain. This condition requires immediate attention, or testicular loss is virtually certain.
UDS (urodynamic study): This test is performed by a urologist to determine causes of abnormal voiding patterns, and to determine whether a patient’s kidneys are at risk of damage from voiding dysfunction.
Ultrasound: an imaging technique for visualizing kidney, bladder, testicles, and other anatomies. No radiation. Completely safe. See image below:
Undescended testicle: A testicle that has not descended into the scrotum, as is supposed to occur by 6 months of age. May require orchidopexy.
UPJ obstruction (Ureteral Pelvic Junction obstruction): A congenital condition in which a blockage exists between the kidney and the ureter. May require pyeloplasty. See image below:
Ureter: A tube that drains urine from the kidney to the bladder. Each kidney has its own ureter, so most individuals have a left and a right ureter. See image below:
Ureterocele: abnormal connection of the ureter into the bladder which may cause obstruction and require surgical correction.

Urologist: Physician specializing in surgical and non-surgical diseases of the male and female urinary and reproductive tracts.
UVJO: Ureteral Vesical Junction Obstruction. Congenital condition in which a blockage exists between the ureter and bladder. This may require a ureteral reimplant. See image below:
