Abstract

We present updated, evidence-based clinical practice guidelines from the Indian Society of Pediatric Nephrology (ISPN) for the management of urinary tract infection (UTI) and primary vesicoureteric reflux (VUR) in children. These guidelines conform to international standards; Institute of Medicine and AGREE checklists were used to ensure transparency, rigor, and thoroughness in the guideline development. In view of the robust methodology, these guidelines are applicable globally for the management of UTI and VUR. Seventeen recommendations and 18 clinical practice points have been formulated. Some of the key recommendations and practice points are as follows. Urine culture with > 104 colony forming units/mL is considered significant for the diagnosis of UTI in an infant if the clinical suspicion is strong. Urine leukocyte esterase and nitrite can be used as an alternative screening test to urine microscopy in a child with suspected UTI. Acute pyelonephritis can be treated with oral antibiotics in a non-toxic infant for 7–10 days. An acute-phase DMSA scan is not recommended in the evaluation of UTI. Micturating cystourethrography (MCU) is indicated in children with recurrent UTI, abnormal kidney ultrasound, and in patients below 2 years of age with non-E. coli UTI. Dimercaptosuccinic acid scan (DMSA scan) is indicated only in children with recurrent UTI and high-grade (3–5) VUR. Antibiotic prophylaxis is not indicated in children with a normal urinary tract after UTI. Prophylaxis is recommended to prevent UTI in children with bladder bowel dysfunction (BBD) and those with high-grade VUR. In children with VUR, prophylaxis should be stopped if the child is toilet trained, free of BBD, and has not had a UTI in the last 1 year. Surgical intervention in high-grade VUR can be considered for parental preference over antibiotic prophylaxis or in children developing recurrent breakthrough febrile UTIs on antibiotic prophylaxis.

Febrile urinary tract infection
Fever (temperature ≥ 38 °C) with a positive urine culture defined by presence of significant colony count of a single uropathogen
High-grade vesicoureteric reflux
Grade 3 to 5 vesicoureteric reflux on micturating cystourethrography
Kidney scarring
Acquired kidney damage due to acute pyelonephritis
Leukocyturia
Presence of ≥ 10 leukocytes per mm3 in a fresh uncentrifuged sample, or > 5 leukocytes per high power field in a centrifuged sample
Low-grade vesicoureteric reflux
Grade 1 and 2 vesicoureteric reflux on micturating cystourethrography
Primary vesicoureteric reflux
The passage of urine from the bladder back into a ureter and kidney in the absence of obstructive uropathy and neurogenic bladder dysfunction
Recurrent urinary tract infection
Two episodes of urinary tract infection during any time period in childhood
Reflux nephropathy
