Childhood urinary incontinence

Advanced and less invasive treatments

Childhood urinary incontinence is the involuntary loss of urine in children who have already reached the usual age of bladder control.
It can have various causes and, in many cases, can improve with behavioral interventions, medical treatment, or a combination of both. The approach is tailored to the cause and the individual needs of each child.

What is it?

Urinary incontinence in children occurs when they experience involuntary urine leakage during the day. This can be due to various anatomical or neurological abnormalities. In the absence of such abnormalities, daytime urinary incontinence is known as functional bladder dysfunction , referring to disorders in the bladder's storage and emptying processes that lead to urinary incontinence in children.

Under normal conditions, the bladder and urinary sphincter work as a coordinated unit, allowing for the storage of urine at low pressure and its voluntary and complete emptying. This control over the timing of urination is usually achieved around 2-3 years of age.

Urinary incontinence significantly affects the quality of life of children who suffer from it and their families, both in the school environment and in their personal relationships.

If, during this phase, the bladder experiences uninhibited contractions, the patient will feel an urgent need to urinate, resulting in urinary incontinence. This is called overactive bladder and is characterized by the need to urinate very frequently but in small amounts.

Weakness of the urinary sphincter can also be responsible for urine leakage during bladder filling, coinciding with laughter or physical exertion.

This dysfunction is known as uncoordinated urination, and it leads to incomplete bladder emptying, recurrent urinary tract infections, and urine leakage.

Filling dysfunction : During the bladder filling phase, the bladder must relax to hold urine without pressure, and the sphincter, on the contrary, must contract to prevent urine loss.

This is called overactive bladder and is characterized by the need to urinate very frequently but in small amounts. It usually occurs between the ages of 6 and 7 and is very common.

Voiding dysfunction : During the bladder emptying phase, it is common for children to postpone urination by voluntarily contracting the bladder sphincter and using retention maneuvers (crossing their legs, squatting, etc.). If this situation persists, it leads to a disruption of the normal voiding cycle between the bladder and the sphincter.

This disorder is frequently associated with constipation-encopresis and requires joint assessment for pelvic floor rehabilitation.

To diagnose urinary incontinence in children, it is important to know when urine leakage occurs in order to identify the type of incontinence and its possible causes. Likewise, it is essential to individualize the diagnostic protocol for each patient, minimizing unnecessary tests and ensuring an accurate diagnosis.

  • Clinical examinationIt is important to conduct a thorough clinical examination through questioning to understand the situations in which the escapes occur and the patient's routines.
  • Voiding diaryKeeping a voiding diary helps the patient and their family become aware of voiding habits and usual fluid intake, and to make modifications, together with the specialist, that help them achieve continence.
  • Urine analysisSince urinary incontinence is often associated with urine infectionsWe will perform a urine culture test on patients in whom there is a reasonable diagnostic doubt or who need to rule out infection.
  • Flowmetry with electromyogram and residual measurementUroflowmetry is a non-invasive and painless test that we perform in the pediatric urology clinic under comfortable conditions so that the child is relaxed and in a favorable environment. After the test, we will perform a ultrasound to see if there is any urine left in the bladder and to quantify it.
  • UltrasoundIn specific cases, an ultrasound is performed to rule out anatomical abnormalities and assess the condition of the upper urinary tract.
  • Voiding cystographyIn some patients, uncoordinated urination can lead to vesicoureteral reflux (which occurs when urine from the bladder flows backward and up into the ureters, instead of out through the urethra) and the need to perform this test.
  • Urodynamic studiesAlthough they are also available, they are not routinely performed in all cases of incontinence.

After making a good diagnosis of urinary incontinence in the child and getting to know his routines, the pediatric urologist will gradually adapt new habits to his life.

Conservative treatment : This is the first step in the recommended treatment for all patients, regardless of the type of incontinence they have. Conservative treatment includes a combination of hygiene and dietary measures and bladder retraining, requiring the involvement of the patient and family, and follow-up by a specialist physician.

There are also many therapeutic options to help patients manage urinary incontinence, including:

Biofeedback : This technique uses a sensor system to allow the patient to be aware, in real time, of various physiological parameters that describe how their body functions. In a comfortable and relaxed environment, the child will learn, painlessly and using a computer program, to contract and relax their pelvic floor muscles, helping them regain a normal urination rhythm, prevent infections, and recover their self-confidence. These exercises should then be repeated at home to strengthen the pelvic floor and achieve the desired results.

Posterior tibial stimulation : is a painless, in-office treatment to help restore the normal urination cycle and improve urinary incontinence.

Surgery : When these treatments are insufficient, surgical treatment may also be indicated in certain patients, including cystoscopic application of botulinum toxin to the urinary sphincter for the treatment of sphincter hypertonia or, in the bladder, for the treatment of uninhibited contractions that do not respond to conservative treatment.

In patients with congenital or acquired urological pathologies, there are multiple surgical treatment options to improve urinary continence, making it essential to individualize the treatment according to the situation and needs of each patient.
