These guidelines have been drafted by the Urological Society of India Pediatric Urinary Tract Infection (UTI) Guidelines Panel and address “Pediatric Urinary Tract Infection.” The guidelines are intended for urologists to provide recommendations for the diagnosis, treatment, and imaging of infants and children presenting with first or recurrent upper or lower UTIs in Indian settings and the recommendations are updated till October 2019. These will remain valid until the next update or for a maximum period of 5 years. The guidelines should not be regarded as a rigid clinical pathway for every patient and are not intended to replace clinical judgment. This executive summary includes some salient aspects of the guidelines and the guideline statements. The complete guidelines document can be accessed from the Urological Society of India website at www.usi.org.in (https://www.usi.org.in/pediatric-uti-guidelines/).

The recommendations in these guidelines were developed after a review of the literature from National Institute for Health and Clinical Excellence guidelines, American Academy of Pediatrics (AAP) guidelines, European Society of Pediatric Urology, Urological Clinic of America, Indian Society of Pediatric Nephrology guidelines, and a search of PubMed for UTI, newborn, infants, preschool, school, child, and adolescent.[1],[2],[3],[4],[5],[6],[7],[8] Special attention was given to publications made from the Indian subcontinent so as to make these recommendations aptly applicable to local needs and clinical circumstances.[9],[10] A consensus decision was adopted when evidence was low. In these cases, all relevant papers and statements were discussed by all the authors until a consensus was achieved. The guidelines panel based its final recommendations on the best available global evidence, Indian data, as well as the socioeconomics of healthcare in India.

UTI is one of the most common bacterial infections in children. The infection may affect the upper urinary tract (referred to as pyelonephritis) or the lower urinary tract (referred to as cystitis). From a practical point of view, these two conditions are discussed together under the umbrella of UTI.[11] The high incidence, tendency to relapse, associated morbidity, and problems with the collection of an uncontaminated urine specimen present significant challenges to a clinician.[11] UTI is a significant concern for children, parents, and clinicians alike. Since UTI can present with vague clinical complaints, UTI should be considered in any infant or child presenting with fever without an obvious source of infection. Prompt diagnosis and early therapy are crucial in the prevention of long-term UTI-related complications.[12]

According to global studies, the overall prevalence of UTIs among febrile infants and young children is estimated to be approximately 4%–7%.[12],[13] However, it varies according to the age, sex, race, nutritional state, state of circumcision, and other factors.[11] The prevalence also seems to be increasing over time. The average prevalence of UTIs among children reported by the AAP in 1999 was 5%.[14] Shaikh et al., in their meta-analysis in 2008, reported an average prevalence rate of 7% among febrile children below 2 years of age.[15] The prevalence rate varied between 5.5 and 8.1 among the studies.[16],[17]

Unfortunately, observational studies on UTIs in Indian children are very less with few available studies, showing a prevalence of 4%–5% in febrile children.[9],[10] In a developing country like India with a huge population of which a significant portion is going to be made of young children, it is imperative that we have defined protocols for managing and treating UTI.

 Guideline Statements



Diagnostic workup

Proper history-taking includes questions on primary (first) or secondary (recurring) infection, febrile or nonfebrile UTIs, malformations of the urinary tract, previous surgeries, fluid intake, family history, whether there is constipation/encopresis or the presence of lower urinary tract symptoms, and sexual history in cases of adolescentsFever may be the only symptom of UTI, especially in young childrenNewborns with pyelonephritis or urosepsis can present with nonspecific symptoms (failure to thrive, jaundice, vomiting, hyperexcitability, lethargy, hypothermia, and sometimes without fever)Septic shock is unusual even with high fever, unless obstruction is present or the child is otherwise compromisedA complete physical examination is required to exclude any other source of fever, and especially if the fever has no apparent cause, UTI should be ruled outPhysical examination should search for palpable bladder, palpable and painful kidney, loaded colon suggestive of constipation, stigmata of spina bifida or sacral agenesis, spine and gait abnormality, genital disorders (phimosis, labial adhesion, postcircumcision meatal stenosis, abnormal urogenital confluence, cloacal malformations, vulvitis, epididymo-orchitis, and prolapsed ureterocele), and raised temperature.

Diagnosis of urinary tract infection

The diagnosis should be based on the presence of both pyuria and >105 CFU/ml in a clean-catch midstream voided urine sampleIf urine is obtained by catheterization, 1000–50,000 CFU/ml is considered positive in symptomatic patientAny counts obtained after suprapubic aspiration should be considered significant.

Acute management

Infants and children with a high risk of serious illness should be referred urgently to the care of pediatric specialist having access to both pediatric urologist and nephrologistEmpiric antibiotic therapy can be started if the child is too sick even before the urine culture and sensitivity report is availableFor lower tract (cystitis), most children can be treated with oral antibiotics as per the urine culture and sensitivity reportFor upper tract (pyelonephritis), parenteral antibiotics should be started until the child exhibits clinical improvement, generally within 48–72 h, and is able to retain orally administered fluids and medications that is to be continued for the next 10 daysThe total course of antibiotic therapy should be 7–14 days.

Imaging after the first urinary tract infection

The aim of investigations is to identify patients at high risk of renal damage, chiefly those below 1 year of age, and those with vesicoureteric reflux (VUR) or urinary tract obstructionEvaluation includes ultrasonography, dimercaptosuccinic acid renal scan, and voiding cystourethrogram performed judiciously as shown in [Table 1].{Table 1}

Prevention of recurrence

Children who have had a UTI should be encouraged to drink an adequate amount of liquids (~40 ml/kg/day)Children who have had a UTI should have readily access to clean toilets when required and should be encouraged to avoid postponing voidingBladder bowel dysfunction and constipation should be addressed in infants and children who have had a UTIIn children with VUR who are toilet trained, regular and volitional low pressure voiding with complete bladder emptying is encouraged. Double voiding ensures emptying of the bladder of postvoid residual urineCircumcision reduces the risk of recurrent UTI in infant boys and might therefore have benefits in patients with high-grade reflux.

Antibiotic prophylaxis

The antibiotics used should be effective, nontoxic with few side effects and should not alter the growth of commensals or induce bacterial resistanceAntibiotic prophylaxis should not be routinely recommended in infants and children following the first-time UTIThe indications and duration of prophylaxis depend on patient's age and presence or absence of VURAntibiotic prophylaxis is recommended for patients with UTI below 1 year of age, while awaiting imaging studies?, VUR (all grades in infants <2 years, dilating VUR, Grade III–V in 2–5 years), and recurrent febrile UTI (3 or more episodes in a year) even if the urinary tract is normalAntibiotic prophylaxis is not advised in patients with urinary tract obstruction (e.g., posterior urethral valves), urolithiasis, and neurogenic bladder and in patients on clean intermittent catheterization. In these cases, the primary cause needs to be addressed firstAsymptomatic bacteriuria in infants and children should not be treated with prophylactic antibioticsBreakthrough UTI usually results either from poor compliance or associated voiding dysfunction. The UTI should be treated with appropriate antibioticsA change of medication being used for prophylaxis is usually not necessaryThere is no role for cyclic therapy, where the antibiotic used for prophylaxis is changed every 6–8 weeks.

Follow-up

When results are satisfactory, a follow-up outpatient appointment is not routinely requiredParents or caregivers should be informed of the results of all the investigations in writingInfants and children who have recurrent UTI or abnormal imaging results should be assessed by a pediatric urologistAssessment of infants and children with renal parenchymal defects should include height, weight, blood pressure, and routine testing for proteinuriaInfants and children with a minor, unilateral renal parenchymal defect do not need long-term follow-up unless they have recurrent UTI or family history or lifestyle risk factors for hypertensionInfants and children who have bilateral renal abnormalities, impaired kidney function, raised blood pressure, and/or proteinuria (random spot protein creatinine ratio >0.2 suggesting significant proteinuria) should receive monitoring and appropriate management by a pediatric nephrologist to slow the progression of chronic kidney diseaseInfants and children who are asymptomatic following an episode of UTI need not routinely have their urine re-tested for infection (no screening urinalysis or culture)Asymptomatic bacteriuria is not an indication for follow-up.
