UTI in children: when do you need a surgeon

Recurrent Urinary Tract Infections (UTI) in children are distressing and can lead to an escalating cycle of symptoms. Parents rightly worry about long-term damage to the kidneys and urinary tract. When are surgeons needed?

Paediatric urologists are specialist surgeons trained to perform procedures on children. Children have particular problems of childhood that may not be seen in adulthood. Paediatric urologists can be Adult Urology surgeons with a special interest in children’s problems. They can also be Paediatric Surgeons, with a special interest in urological problems. Both approaches are well established. Surgeons are typically happy to discuss their background and specialist skills, and parents should feel confident to discuss these questions openly.

A surgeon’s role in recurrent UTI risk factors driving infection, and try to identify some reversible causes. Surgeons need to get involved in three general circumstances:

1. Structural anomaly in the urinary tract

2. Dysfunctional voiding

3. Neuropathic bladder

Structural anomalies

These are best considered at three levels i.e. Kidneys, the ureters draining the kidneys, and the bladder. Anatomical problems are detected with ultrasound in children. Extra dynamic information can be obtained from more specialist xray (MCUG study) and nuclear medicine ( DMSA, MAG3) studies.

Kidney: Hydronephrosis, pelvi-ureteric junction obstruction (PUJO), cystic and dysplastic kidneys

Ureter: Hydroureteronephrosis, vesicoureteric reflux

Bladder: Posterior urethral valves, urethral stenosis, meatal stenosis

Dysfunctional voiding

This describes a discoordination between the bladder filling and emptying muscles. This is often an acquired condition that can lead to incomplete emptying of the bladder. This in turn increases risk of recurrent UTI. In addition to ultrasound, paediatric urologists will review voiding patterns using diaries and/ or bladder volume assessment . Parents should expect support investigating the cause, and supporting with bladder training and medications to help return the bladder to a normal pattern.

Neuropathic bladder

This phrase describes a bladder that has lost its nerve supply. More specialist tests are needed to confirm this condition e.g. ultrasound, MRI of spine, urodynamic tests. Once a diagnosis is made, a surgeon is needed to shepherd a child through the various phases of neuropathic bladder. In addition to preventing further urinary tract infection, surgeons are focused in preventing scarring of kidneys. Scarring on kidneys is a long term predicter of hypertension and kidney failure.

Burns in Children: what to expect

A child getting burned is a nightmare scenario for any parent or caregiver. Burns in children are most commonly scalding accidents (80%) involving hot water or steam, or open flame burns (14%).

Burns lead to trauma and disability, and can result in a long hospital stay, multiple surgeries and sometimes, life-long impairment of functions. Generally, the more severe the burn, the more likely your child is to need hospital admission, critical or intensive care, and surgery.

First steps: Assessment of burn severity

First aid involves making the child safe (e.g. remove them from the hazard, extinguish the flame etc) and arresting the burn process. This is done by cooling. Remove clothes involved in the scald or burn, irrigate the area with cool water. Cooling cloths, cooling gels as you take the child to the medical centre will help.

Your treatment team will need to decide whether the burn is a “see and treat” or a “see and send”.

This decision is based on burn severity. These grades are assessed based on several factors:

1.Size of burn area: There are several ways to assess area burned. Generally, the team will map the burned areas and assign a percentage e.g. 15% burns.

2. Depth of burn: You may have heard of 1st, 2nd and 3rd degree burns.

3. Body areas

4. Mechanism

A 1st degree burn is superficial and affects the top skin layers. It is quite painful and may increase redness in that area, but the skin remains unbroken in most parts. Scalding injuries and sunburn are good examples.

2nd degree burns involve deeper layers of the skin. The skin is broken , blistering and weeping in parts. These are painful too, as the nerves within the deeper skin layers are triggered. Contact injuries e.g. hot iron, can create burns like this.

3rd degree burns are deeper still. All the skin layers are burned, leaving connective tissue overlying the fat and muscles (fascia) exposed. These take on a dry, waxy, leathery appearance. These are severe because these deeper structures tissues will need to be covered , and skin may need to be taken from other body areas (grafted) to achieve this.

Special body areas:

Burn site matters. Burns to certain body areas are considered severe, due to the level of disability or disfigurement resulting. These special areas are:

1. Face

3. Airway/ inhalation injuries: a burn that affects the throat externally or internally can lead to breathing problems

2. Genitals and perineum

4. Hands and feet

Special mechanisms

Some mechanisms of injury can cause more damage than others. For example:

-Electric burns have an unpredictable course, causing damage between the current’s entry site and its final discharge site

-Chemical burns may need specialised treatment with neutralising agents

If in doubt, treatment teams can seek specialist input from a hospital specialised to deal with burns.

The burn is severe. Now what?

Small and superficial burns can be treated with first aid. Treatment teams will make a plan for pain control, and monitoring the burn area to ensure there is no infection developing. However, the body heals by forming scars. Therefore, burns in sensitive areas e.g. hands will need a plan for follow-up, to ensure that scarring does not lead to disability.

More severe burns need immediate stabilisation. The child will receive a cannula and a drip will be started. Keeping the child hydrated is part of immediate resuscitation.

If there is significant concern about fluid loss, a catheter tube may be used to empty the bladder and measure urine volume produced.

If there is concern about the throat closing over due to smoke inhalation or face and neck burns, a breathing tube may be placed to secure the airway and enable breathing.

Bigger, deeper burns, or burns involving special body sites need specialist review i.e. “see and send”.

Different countries and regions have diverse ways of organising burns services. However, the priority for treatment is:

Early

–effective pain control

-prevent dehydration from fluid loss

-prevent infection, leading to sepsis

During this phase of injury, severe cases may require treatment in intensive care, to support breathing , circulation and sepsis prevention and treatment. General and plastic surgeons may be involved , to begin the management of wounds and supported healing.

Mid term to late

-prevent scarring

-prevent loss of function / disability

For this phase of injury, the child may need input from general and plastic surgeons with specialist knowledge in this area.

Importantly, the psychological consequences of injury should be considered and support put in place.

Non-accidental injury

As part of a child’s safety, treatment teams will think about non-accidental injury. Treatment teams must consider the mechanism of injury, and how it may be prevented from happening again. This will involve a review of the child’s medical, social and education history. Parents and care givers may be asked probing questions. Ultimately, the goal is to prevent further episodes and ensure the child’s and family’s safety.

Global trends

In 2018 the World health organisation launched the Global Burn Registry. From these data, it appears that burns occur most commonly in children from middle-income countries. In 2021, review of these data demonstrated and average age of 5 years, and that 60% were boys.

Constipation: when do you need a biopsy?

Constipation is a common problem in childhood. Very rarely, an underlying and serious problem i.e. Hirschsprung’s disease, can be detected on biopsy. Importantly, most biopsies done are actually negative.

For parents, it can be quite difficult to decide if the time has come to discuss a biopsy with your paediatrician.

Here are some facts about rectal biopsies for constipation.

To do, or not to do

Does my child need a circumcision?

This is a question many parents will ask. Where there is a medical reason to do a circumcision, parents should have a good understanding of the indications, to prepare for the discussion with a specialist.

Where there are no religious or cultural reasons to have a circumcision, parents should get as much information as possible from a specialist source.

Here’s some valuable information from London Children’s Surgery.
