Frequently Asked Questions
❓ What is vesicoureteral reflux in children?
Vesicoureteral reflux is a condition in which urine flows backward from the bladder into the ureters and sometimes the kidneys due to an abnormal ureterovesical junction. It increases the risk of recurrent urinary tract infections and kidney damage in children.
❓ What are the common causes of urinary tract infection in children?
The most common cause of urinary tract infection in children is Escherichia coli. Other organisms include Klebsiella, Proteus, Enterococcus and Pseudomonas. Risk factors include vesicoureteral reflux, poor hygiene, constipation, urinary obstruction and neurogenic bladder.
❓ What are the symptoms of urinary tract infection in children?
Symptoms vary by age. Infants may have fever, irritability, vomiting and poor feeding. Older children commonly present with dysuria, urinary frequency, urgency, abdominal pain, flank pain and fever.
❓ How is vesicoureteral reflux diagnosed in paediatrics?
The gold standard test for diagnosing vesicoureteral reflux is a voiding cystourethrogram. Ultrasound is often used as an initial screening test, while a DMSA scan helps detect renal cortical scarring.
❓ What is the grading system for vesicoureteral reflux?
Vesicoureteral reflux is graded from I to V. Grade I involves reflux into the ureter only, Grade II reaches the renal pelvis without dilation, Grade III shows mild dilation, Grade IV shows moderate dilation and Grade V represents severe dilation with loss of papillary impressions.
❓ What complications can occur from untreated vesicoureteral reflux?
Untreated vesicoureteral reflux can lead to recurrent urinary tract infections, pyelonephritis, renal scarring, reflux nephropathy, hypertension and chronic kidney disease.
❓ What imaging tests are used for pediatric urinary tract infections?
Common imaging tests include renal ultrasound to detect structural abnormalities, voiding cystourethrogram to identify vesicoureteral reflux and DMSA renal scan to evaluate renal scarring.
❓ How are urinary tract infections treated in children?
Treatment usually involves antibiotics such as amoxicillin clavulanate, cephalosporins or ceftriaxone in severe cases. Hydration, fever control and addressing underlying causes like constipation are also important.
❓ When is surgery required for vesicoureteral reflux?
Surgery may be required in children with high grade reflux, recurrent infections despite antibiotic prophylaxis or progressive renal scarring. Surgical options include endoscopic injection therapy and ureteral reimplantation.
❓ How can recurrent urinary tract infections in children be prevented?
Prevention includes good hydration, proper perineal hygiene, treating constipation, regular bladder emptying and antibiotic prophylaxis in selected children with vesicoureteral reflux.
