Hypospadias is a condition in infant boys in which the opening that carries urine out of the body (the urethra) is on the underside, rather than the tip, of the penis. It’s a congenital condition, or present at birth, and that’s when you or your child’s doctor may first notice it.
There are different degrees of hypospadias, with the urethral opening appearing anywhere along the length of the penile shaft. Most are mild or moderate and a small percentage are severe. Hypospadias may cause your child to have a deflected urine stream.
There may also be other penile abnormalities associated with hypospadias. For example, the skin that covers the urethra is often thin and poorly developed and can result in bending of the penis, causing it to curve. This curvature is called a chordee. Although hypospadias may run in families, there’s no single known cause of the condition.
You might feel worried if your son is born with hypospadias, but you should know that it is a common condition. Nemours pediatric urologists are experienced at repairing the problem and restoring the appearance and function of your child’s penis.
Our Nemours urologists correct hypospadias with surgery that is usually performed when your son is older than 4 months of age. Depending on the severity of hypospadias, our doctor may perform straightening of the penis, relocation of the meatus (urethra opening) to the tip of the penis and the creation of a cosmetic glans (head of the penis) and penile shaft.
The goal of hypospadias repair is to normalize urination, create normal erections, and to improve the cosmetic appearance of the penis. The surgery is often same day surgery, and the overall results are excellent, with children going on to have normal urinary and sexual function in adulthood.

Recurrent Urinary Tract Infections and Related Conditions
Urinary tract infections (UTIs) are common in kids, especially girls and uncircumcised boys. In fact, by age 5, about 8% of girls and 1%–2% of boys have had at least one UTI.
UTIs happen when the kidneys, ureters, bladder, or urethra become infected. Symptoms of a UTI can include:
- pain when urinating
- changes in frequency of urination
- changes in appearance or smell of urine
- loss of appetite
- lower abdominal pain
- lower back pain or discomfort
UTIs also can cause kids to wet their pants or the bed, even if they haven't had these problems before. Infants and very young children may only show nonspecific signs, such as fever, vomiting, or decreased appetite or activity.
Some kids get UTIs again and again — these are called recurrent UTIs. If not treated, recurrent UTIs can cause kidney damage, especially in kids younger than 6. So it's important to know how to recognize the signs of these infections and get help for your child.
Types of UTIs
Common types of UTIs include:
- cystitis: this bladder infection is the most common type of UTI. Cystitis occurs when bacteria move up the urethra (the tube-like structure that allows urine to exit the body from the bladder) and into the bladder
- urethritis: when bacteria infect the urethra
- pyelonephritis: a kidney infection caused by infected urine flowing backward from the bladder into the kidneys or an infection in the bloodstream reaching the kidneys
Recurrent UTIs sometimes happen along with other conditions, such as:
- vesicoureteral reflux (VUR), which is found in 30%–50% of kids diagnosed with a UTI and is a congenital (present at birth) condition in which urine flows backward from the bladder to the ureters. Ureters are thin, tube-like structures that carry pee from the kidney to the bladder. Sometimes the pee backs up to the kidneys and if it is infected with bacteria, can lead to pyelonephritis.
- hydronephrosis, which is an enlargement of one or both kidneys due to backup or blockage of urine flow and is usually caused by severe VUR or a blocked ureter. Kids with hydronephrosis are sometimes at risk of recurrent UTIs and may need to take daily low doses of antibiotics to prevent UTIs until the condition producing hydronephrosis gets better or is fixed through surgery.
But not all cases of recurrent UTIs can be traced back to these body structure-related abnormalities. For example, dysfunctional voiding — when a child doesn't relax the muscles properly while urinating — is a common cause of UTIs. Infrequent urination (not peeing often enough) also can also increase a child's risk for recurrent infections. Both dysfunctional voiding and infrequent urination can be associated with constipation.
Unrelated conditions that harm the body's natural defenses, such as diseases of the immune system, also can lead to recurrent UTIs, although this is rare. In addition, use of a nonsterile urinary catheter can introduce bacteria into the urinary tract and cause an infection.
Although UTIs can be treated with antibiotics, it's important for a doctor to rule out any underlying abnormalities in the urinary system when UTIs happen repeatedly. Kids with recurrent infections should see a pediatric urologist to see what is causing the infections.
Some abnormalities can be found even before birth. Hydronephrosis that develops before birth can be detected in a fetus by ultrasound as early as 16 weeks of gestation. In rare cases, doctors may consider neonatal surgery (performing surgery on an unborn baby) if hydronephrosis affects both kidneys and poses a risk to the developing fetus. Most of the time, though, doctors wait until after birth to treat the condition, because almost half of all cases diagnosed prenatally disappear by the time a baby is born.
Once a baby suspected to have hydronephrosis or another urinary system abnormality is born, the baby's blood pressure will be monitored carefully, because some kidney abnormalities can cause high blood pressure. An ultrasound may be used again to get a closer look at the bladder and kidneys. If the condition appears to be affecting both kidneys, doctors usually will order blood tests to measure kidney function.
If an abnormality of the urinary tract is suspected, doctors might order tests to make an accurate diagnosis, including:
Using high-frequency sound waves to "echo," or bounce, off the body and create a picture of it, an ultrasound can detect some abnormalities in the kidneys, ureters, and bladder. It can also measure the size and shape of the kidneys.
When an ultrasound points to VUR or hydronephrosis, a renal scan or voiding cystourethrogram (VCUG) might give doctors a better idea of what's going on.
Renal scan (nuclear scan)
Radioactive material is injected into a vein and followed through the urinary tract. The material can show the shape of the kidneys, how well they function, if there is damaged kidney tissue, and the course of the urine. A small amount of radiation is received during the test and leaves the body in the urine.
Voiding cystourethrogram (VCUG or cystogram)
A catheter (a hollow, soft tube) is used to inject an opaque dye into the bladder. This X-ray test can diagnose VUR and identify problems with the bladder or urethra.
A cystoscope uses lenses and a light source within a tube inserted through the urethra to directly view the inside of the bladder. It's used when other tests or symptoms indicate a possible bladder abnormality.
Opaque dye is injected into a vein, and then X-rays are taken to follow the course of the dye through the urinary system. Although this test is still used sometimes, the renal MRI and renal scan have replaced intravenous pyelogram in most cases.
Magnetic resonance urography (MR-U)
This procedure, which makes a magnetic resonance imaging (MRI) scan of the urinary tract without the use of dyes or radioactive materials, has been shown to be as accurate as other scans and is now typically done in place of an intravenous pyelogram.
Treatment for recurrent UTIs depends on what's causing them in the first place. Sometimes the answer is as simple as teaching a child to empty the bladder as soon as he or she has the urge to go.
If a condition like VUR is causing the infections, then the solution is a bit more complicated. Kids with VUR must be monitored closely, because the condition can lead to kidney infection (pyelonephritis) and subsequent kidney damage. Usually, surgery isn't necessary, because many kids outgrow the condition.
Some kids with VUR benefit from daily treatment with a small amount of antibiotics, which can also make surgery unnecessary. Kids with VUR should be examined by a pediatric urologist to decide if antibiotic treatment is the best option for them.
In some cases, surgery is necessary to correct VUR. The most common type of surgery used is ureteral reimplantation, in which one or both of the ureters are repositioned to correct the backflow of urine from the bladder. The procedure can be done through a small incision. The success rate for this surgery is high, although not everyone is a good candidate for surgery.
Kids with the following situations may be candidates for ureteral reimplantation:
- intolerance to antibiotics
- recurrent infections while on antibiotic treatment
- severe, or "high-grade," reflux
- older kids and teens with reflux
An alternative to ureteral reimplantation is endoscopic injection of a material to block the entry of the ureter into the bladder and prevent VUR. In this procedure, a narrow tube called an endoscope is inserted through the urethra into the bladder. The endoscope has a tiny camera at the tip, allowing the surgeon to guide it to the proper location and inject the material, which helps keep urine from refluxing back into the kidneys. Endoscopic injection is less invasive than surgery, but the results are not as good. A pediatric urologist can help families decide the best treatment for a child with VUR.
Kids who have recurrent infections that are not caused by anatomical defects or other treatable problems may be prescribed antibiotics for months or even years to prevent recurrent infections. This form of treatment is known as continuous antibiotic prophylaxis.
The Future for Managing Recurrent UTIs
Recent studies have found that women and kids who get recurrent UTIs may lack certain immunoglobins (a group of proteins that fight infections). Some researchers are optimistic that a vaccine may be developed to help boost production of antibodies that fight UTIs. A promising vaccine that would protect against E. coli (the most common bacterium that causes UTIs) is being tested.
Additional things to consider to help prevent recurrent UTIs in kids:
Encourage kids to drink 8 to 10 glasses of water and other fluids per day. Cranberry juice and cranberry extract are often suggested because they may prevent E. coli from attaching to the walls of the bladder. Always ask your doctor, though, if your child should drink cranberry juice or cranberry extract, because they can interfere with some medicines.
Good Bathroom Habits
Frequent emptying of the bladder, normal urination and prevention of constipation can all help to prevent recurrent infections.
Vitamin C acidifies the urine, making the environment less friendly to bacteria. Vitamins designed for kids are generally safe, but always ask your doctor before increasing the dose beyond the currently recommended daily allowance.
No Bubble Baths
Kids should avoid bubble baths and perfumed soaps because they can irritate the urethra.
Frequent Diaper Changes
Kids in diapers should be changed frequently to prevent stool from having prolonged contact with the genital area, which can increase the chance that bacteria will move up the urethra and into the bladder.
Proper Wiping Technique
In females, wiping from front to back after using the toilet will reduce exposure of the urethra to UTI-causing bacteria in the stool.
Breathable cotton underwear is less likely to encourage bacterial growth near the urethra than nylon or other fabrics.
Frequent Bathroom Visits
Some kids may object to using the school bathroom or may become so engrossed in a project that they delay urination. Kids with UTIs should pee at least every 3 to 4 hours to help flush bacteria from the urinary tract.
When to Call the Doctor
As soon as you suspect that your child has a UTI, it's important to contact your doctor. The doctor may recommend another urine culture after treatment to be sure that the infection has cleared.
If your child suffers from recurrent UTIs, consult a pediatric urologist, who can perform a thorough evaluation and, if necessary, order tests for urinary system abnormalities. In the meantime, follow your doctor's instructions for treating a UTI.
