Predictive factors for prolonged hospitalisation in acute pyelonephritis patients admitted to the emergency medicine ward

Background: Acute pyelonephritis is a bacterial infection of the upper urinary tract. Patients can be admitted to a variety of wards for treatment. However, at the Prince of Wales Hospital in Hong Kong, they are managed initially in the emergency medicine ward. The aim of the study is to identify the risk factors that are associated with a prolonged hospital length of stay. Methods: This was a retrospective cohort study conducted in Prince of Wales Hospital. The study recruited patients who were admitted to the emergency medicine ward between 1 January 2014 and 31 December 2017. These patients presented with clinical features of pyelonephritis, received antibiotic treatment and had a discharge diagnosis of pyelonephritis. The length of stay was measured and any length of stay over 72 h was considered to be prolonged. Results: There were 271 patients admitted to the emergency medicine ward, and 118 (44%) had a prolonged hospital length of stay. Univariate and multivariate analyses showed that the only statistically significant predictor of prolonged length of stay was a raised C-reactive protein (odds ratio 1.01; 95% confidence 1.01–1.02; p < 0.0001). Out of 271 patients, 261 received antibiotics in the emergency department. All 10 patients (8.5%) who did not receive antibiotics in emergency department had a prolonged length of stay (p = 0.0002). Conclusion: In this series of acute pyelonephritis treated in the emergency medicine ward, raised C-reactive protein levels were predictive for prolonged length of stay. Patients who did not receive antibiotics in the emergency department prior to emergency medicine ward admission had prolonged length of stay.

Neutrophil gelatinase-associated lipocalin for urinary tract infection and pyelonephritis: a systematic review.

The sensitivity and specificity of the leukocyte esterase test are relatively low for a screening test for urinary tract infection (UTI). More accurate tests could reduce both overtreatment and missed cases. This study aimed to determine whether neutrophil gelatinase-associated lipocalin (NGAL) can replace leukocyte esterase in the diagnosis of UTI and/or whether NGAL accurately identifies children with acute pyelonephritis. Data sources-MEDLINE and EMBASE. We only considered published studies that evaluated the results of an index test (NGAL) against the results of urine culture (for UTI) or against the results of dimercaptosuccinic acid (for acute pyelonephritis) in children aged 0 to 18years. Two authors independently applied the selection criteria to all citations and independently extracted the data. A total of 12 studies met our inclusion criteria. Four studies (920 children) included data on NGAL for UTI; eight studies (580 children) included data on NGAL for pyelonephritis. We did not pool accuracy values because the included studies used different cutoff values. For the diagnosis of UTI, urinary NGAL appeared to have better accuracy than the leukocyte esterase test in all included studies. For the diagnosis of pyelonephritis, neither plasma NGAL nor urinary NGAL had high sensitivity and/or specificity. The number of studies was the main limitation of this systematic review. Urinary NGAL appears promising for the diagnosis of UTI; however, larger studies are needed to validate this marker as a replacement for leukocyte esterase. The use of NGAL for diagnosing acute pyelonephritis requires further study.

Biotechnical System of Differential Diagnostics of Serous and Purulent Pyelonephritis in Pregnant Women Based on Fuzzy Logic for Decision-Making.

Urologists and nephrologists attribute pyelonephritis of pregnant women to the category of complicated upper urinary tract infections that threaten the development of a severe purulent-septic process. The frequency of pyelonephritis in pregnant women ranges from 12.2 to 33.8%. In this research, laboratory indicators of the state of immunity and lipid peroxidation using fuzzy decision logic are used to improve the quality of differential diagnosis of serous and purulent pyelonephritis in pregnant women. A space of informative indicators was formed that characterize the state of immune changes, making it possible to carry out the differential diagnosis of pyelonephritis forms in pregnant women with high accuracy. Results of the operation of the obtained decision rules in the control sample showed that the diagnostic efficiency of the proposed method reaches 93%, which is acceptable for use in medical practice.

Serum Interleukin-6 and Interleukin-8 are Sensitive Markers for Early Detection of Pyelonephritis and Its Prevention to Progression to Chronic Kidney Disease.

Background:Pyelonephritis is the most common bacterial infection in children that can cause renal failure if not diagnosed or treated early. We used serum biomarker interleukins (IL-6 and IL-8) and then confirmed the results by the findings dimercaptosuccinic acid (DMSA) scan to distinguish upper-tract infection from lower-tract infection.Methods:Serum IL-6 and IL-8 were measured in 57 children with newly diagnosed untreated urinary tract infection (UTI) documented by a positive urine culture. All children had a DMSA to determine whether serum IL6, IL-8 can be used as a marker to predict upper-tract from lower-tract infection. IL-6 and IL8 were determined by the enzyme link immunosorbent assay (ELISA) technique.Results:Of the 57 patients, 24 (42%) had renal parenchymal lesions on the DMSA scan. Patients with abnormal DMSA had significantly higher serum IL-6 and IL-8 compared with those with normal DMSA scan (187.1 ± 113.1 ng/mL vs. 396.1 ± 246.0 ng/mL, P = 0.005; and 165 ± 76.1 ng/mLvs. 190.8 ± 60.8 ng/mL, P = 0.026, respectively). Pyelonephritis was more frequent in children younger than 20 months old (n = 36, 63%, P < 0.005) and more prevalent in girls (n = 36, 63%, P = 0.005). Serum IL-6 had a sensitivity of 67.3% and a specificity of 63.0% and serum IL8 had a sensitivity of 80.1% and a specificity of 73.5% in the differential diagnosis of pyelonephritis and cystitis (P = 0.03).Conclusions:Serum levels of IL-6 and IL-8 are both sensitive biomarkers of UTI and can discriminate the upper from lower tract urinary infections. Determination of these biomarkers may help to identify patients with acute pyelonephritis and need for DMSA study.

Пути улучшения результатов лечения пациентов с терминальной стадией хронической почечной недостаточности в исходе урологических заболеваний и активным течением пиелонефрита

Introduction. Patients in the outcome of urological diseases after the beginning of treatment with hemodialysis in the presence of permanent drainage in the kidneys, or with recurrent pyelonephritis have high risks of urosepsis and death. In order to improve the results of diagnosis and treatment of this category of patients, we analyzed our own results. Materials and methods. The study included 58 patients with end-stage chronic renal failure (ESRD) who were treated with hemodialysis and had a nephrectomy for active pyelonephritis in the period from 2013 to 2020. Results. The most informative method in the diagnosis of pyelonephritis was magnetic resonance imaging using diffuse-weighted image protocols (MRI-DWI), the diagnostic efficiency was 94%. There were no differences in the frequency of intraoperative complications in laparoscopic and open nephrectomy. The mortality rate after nephrectomy was 25.9% (n=15). With a preoperative C-reactive protein (CRP) level of more than 95 mg/l (p=0.011) and a Charlson comorbidity index of more than 5 (p=0.003), a high probability of death was predicted. Long-term (more than 14 days) antibacterial preoperative therapy was significantly associated with sepsis before surgery, postoperative antibiotic-associated colitis, and infectious-inflammatory complications from the postoperative wound. Discussion. Our work, as well as many other publications, demonstrates a high incidence of septic complications in patients with ESRD. Patients with permanent drainage in the upper urinary tract are most at risk. this study convincingly showed that the results of nephrectomy are significantly worse in the presence of a systemic inflammatory reaction (SIRS), and therefore it is advisable to perform a nephrectomy before the development of SIRS. Our opinion on the possibility and safety of laparoscopic nephrectomy in chronic pyelonephritis in patients with ESRD who have undergone repeated renal interventions is consistent with a number of other studies in recent years. Conclusion. Diagnosis of pyelonephritis in patients with ESRD is advisable to start with MRI-DWI. The results of nephrectomy are better in the absence of a systemic inflammatory response. It is necessary to minimize antibacterial therapy before surgery. Laparoscopic nephrectomy is a safe procedure for inflammatory kidney diseases.

99mTc-dimercaptosuccinic acid scan versus MRI in pyelonephritis: a meta-analysis

Tc-dimercaptosuccinic acid (DMSA) scan is the current gold standard in detecting parenchymal changes, particularly scarring, in pyelonephritis. Recently, magnetic resonance imaging (MRI) is gaining popularity in the diagnosis of pyelonephritis. The aim of this study is to perform a meta-analysis on studies directly comparing MRI to DMSA scan in patients with pyelonephritis. Systematic searches of PUBMED and EMBASE databases were performed to extract studies comparing MRI and DMSA scan in patients with pyelonephritis. The relevance of articles was assessed by two authors according to predefined inclusion and exclusion criteria. The pooled estimates of the sensitivities of MRI and DMSA scan were computed using random-effects meta-analysis model following DerSimonian and Laird's method. Subgroup analysis and publication bias were performed. Seven studies were included (164 patients). Using random effect model, the pooled estimate of the sensitivities of MRI and DMSA scan were 0.62 (95%CI: 0.44 - 0.77) and 0.59 (95%CI: 0.48 - 0.70), respectively. The pooled estimates of sensitivities of MRI and DMSA scan for acute pyelonephritis were 0.73 (95%CI: 0.49- 0.89) and 0.66 (95%CI: 0.56 - 0.75), respectively, and for scar detection were 0.48 (95%CI: 0.31- 0.66), and 0.50 (95%CI: 0.30 - 0.71), respectively. The overall sensitivities of MRI and DMSA scan were equivalent in detecting parenchymal changes in pyelonephritis. MRI and DMSA scan appeared to be equivalent to scar detection. In a small number of studies, MRI appeared to be better than the DMSA scan in acute pyelonephritis but this should be further studied in a larger number of patients.

Diagnostic histologique de lymphome intravasculaire guidé par une hyperfixation corticale rénale à la tomographie par émission de positons : à propos d’un cas

Intravascular large B cell lymphoma is a rare non-Hodgkin large B cell lymphoma disease, with heterogeneous clinical manifestation and difficult pathological diagnosis. Positron emission tomography may be helpfull in this context and has already been reported. A 45-year-old woman was admitted for persistent high fever, inflammatory syndrome and unexplained haemophagocytic syndrome. Bilateral cortical renal hypermetabolism at positron emission tomography initially misled to pyelonephritis diagnosis and secondarily led to kidney biopsy, which showed intravascular large B cell lymphoma. Renal involvement in intravascular large B cell lymphoma is rare and is usually characterized by acute renal failure and proteinuria. Global hypermetabolism at positron emission tomography has already been described in this context, but cortical hypermetabolism has never been associated with pathological findings. In front of persistent high fever without etiology, this positron emission tomography feature must lead to intravascular large B cell lymphoma suspicion and to kidney biopsy to obtain pathological proof.

Urinary carbohydrate antigen 19-9 level as a biomarker in children with acute pyelonephritis.

Early and prompt diagnosis of pyelonephritis is of great importance in children. The aim of this study is to evaluate the diagnostic accuracy of urinary carbohydrate antigen 19-9 (CA19-9) levels for predicting acute pyelonephritis (APN) in children with urinary tract infection (UTI). Patients were allocated into two groups of APN and acute cystitis according to their diagnosis. Urine samples of all patients were collected. Also, complete history was taken, and physical examination, kidney and bladder ultrasonography, 99mTc-dimercaptosuccinic acid renal cortical scintigraphy, and urine analysis and culture were performed. Urinary CA19-9 was measured by an electrochemiluminescence enzyme immunometric kit. In addition, CA19-9 levels were measured in the APN group 2weeks and 3months later. A total of 100 children were included in this study (mean age 46 ± 31months, 16 males and 84 females). CA19-9 levels were significantly greater in the APN group than acute cystitis group (510 ± 328 vs. 18.7 ± 18.6 U/ml, P < 0.001). During follow-up periods of the APN group, CA19-9 levels decreased to 180 ± 124 U/ml after 2weeks (P < 0.001) and 30 ± 23 U/ml after 3months (P < 0.001). Urinary CA-19-9 had 95.3% sensitivity and 80% specificity for the diagnosis of APN. The area under the curve value of CA19-9 was 0.904 (95% CI 0.831-0.977).Conclusion: Urinary CA19-9 level can be used as a reliable biomarker for early detection of APN prior to urine culture confirmation in children with UTI. What is known: • Early and prompt diagnosis of pyelonephritis is necessary in children to prevent renal damage. • Acute pyelonephritis can present with vague and nonspecific symptoms in infants and children. What is new: • Urinary carbohydrate antigen 19-9 is a reliable biomarker for early detection of acute pyelonephritis prior to urine culture confirmation. • Urinary carbohydrate antigen 19-9 has 95.3% sensitivity and 80% specificity for diagnosis of acute pyelonephritis.

Association of Antibiotic Treatment Duration With Recurrence of Uncomplicated Urinary Tract Infection in Pediatric Patients.

Background: Gaps and inconsistencies in published information about optimal antibiotic treatment duration for uncomplicated urinary tract infection (UTI) in pediatric patients pose a dilemma for antibiotic stewardship. Objective: Evaluate the association of antibiotic treatment duration with recurrence rates in children with new-onset cystitis or pyelonephritis. Methods: Retrospective cohort analysis of patients aged 2 to 17 years with new-onset cystitis or pyelonephritis and without renal/anatomical abnormality was conducted using Truven Health MarketScan Database for 2013-2015. Results: Of 7698 patients, 85.5% had cystitis, 14.3% pyelonephritis. Duration of antibiotic treatment was as follows: 3 to 5 days for cystitis (20.4%) or 7 (33.6%), 10 (44.2%), or 14 (1.8%) days for any UTI. Recurrence occurred in 5.5% of patients. Covariates associated with increased recurrence risk included pretreatment antibiotic exposure (odds ratio [OR] = 1.29; 95% CI = 1.06-1.57), pyelonephritis on diagnosis date (OR = 1.44; 95% CI = 1.03-2.00), follow-up visit during antibiotic treatment (OR = 3.21; 95% CI = 2.20-4.68), parenteral antibiotic (OR = 1.89; 95% CI = 1.33-2.69), and interaction of pyelonephritis diagnosis with nitrofurantoin monotherapy (OR = 3.68; 95% CI = 1.20-11.29). After adjustment for covariates, the association between duration of antibiotic treatment and recurrence was not significant (compared with 7 days: 10 days: OR = 1.07, 95% CI = 0.85-1.33; 14 days: OR = 0.89, 95% CI = 0.45-1.78). Conclusions and Relevance: Antibiotic treatment duration was not significantly associated with recurrence of uncomplicated UTI in a national pediatric cohort. Results provide support for shorter-course treatment, consistent with antimicrobial stewardship efforts.

Transition to oral antibiotic therapy for pyelonephritis in children under 60 days of age: An observational retrospective cohort study.

To describe the use of antibiotics and assess if an early transition from intravenous to oral antibiotic therapy is generally safe in infants less than 60 days of age with a diagnosis of pyelonephritis. This retrospective observational cohort study included hospitalized infants less than 60 days with a diagnosis of pyelonephritis based on fever or systemic symptoms and a positive urine culture between January 1, 2015 and July 30, 2017 at a Canadian paediatric tertiary care centre. A total of 108 infants were included. Forty-eight of them were under 1 month of age. The median intravenous (IV) antibiotic therapy duration was 3.5 days, with a longer duration of 4 days in infants less than 1 month of age. The total antibiotic therapy was almost equally divided between a shorter (10 days) and longer (14 days) duration. The recurrence of pyelonephritis within the 2 months following the initial urinary infection was 9 % in the group with IV antibiotic therapy duration of <4 days, compared to 11% in the group treated ≥4 days IV (P-value 0.75). There was a recurrence of pyelonephritis of 10.2% in the group treated for 10 days, compared to 11.5% of recurrence in the group treated for 14 days (P-value 1.0). Our study provides limited retrospective data regarding the management of pyelonephritis in infants less than 60 days of age. Prospective research is needed to confirm those findings.

A Decision Support System for the Differential Diagnosis of Pyelonephritis in Pregnant Women Based on Immune and Oxidative Status

Application of modern mathematical methods and information technologies for accurate differential diagnosis of various forms of pyelonephritis in pregnant women is described. The differential diagnosis is based on indicators of the immune and oxidative status. The decision rules suggested in this work were verified on a control sample. The verification showed that the diagnostic efficiency of the proposed method reaches 93%, which is acceptable for use in medical practice.

Association of mRNA Levels of IL6, MMP-8, GSS in Saliva and Pyelonephritis in Children.

Nowadays, saliva is a subject of growing scientific interest because of its definite advantages as diagnostic medium. The aim of our study was to investigate the diagnostic potential and reliability of messenger RNAs (mRNAs) of selected genes—interleukin-6 (IL-6), matrix metalloproteinase-8 (MMP-8) and glutathione synthetase (GSS)—as salivary markers in children with diagnosed pyelonephritis and to correlate their levels with typical urine para-clinical indicators of the disease. Analysis of the mRNA levels for IL-6, MMP-8 and GSS in 28 children hospitalized with the diagnosis of pyelonephritis was conducted applying the method of quantitative reverse transcription polymerase chain reaction (RT-qPCR). In the study group (n = 28), IL-6 mRNA levels demonstrated 64-fold increase (p < 0.001). MMP-8 and GSS mRNA levels were increased in 12 samples in patients with pyelonephritis 3.27 (p < 0.01) and 1.94 (p < 0.001) times, respectively. We found a strong and significant correlation (p < 0.001) between the investigated mRNA for IL-6 and MMP-8, IL-6 and GSS, MMP-8 and GSS. Moderate degree of correlation was established between IL-6 and the typical para-clinical indicator of leucocytes (0.43, p < 0.05) and between GSS and leucocytes (0.54, p < 0.01). Salivary IL-6, MMP-8 and GSS mRNA levels in combination with urine test analysis could be useful diagnostic tool for the very distributed disorder of pyelonephritis in childhood.

PUK39 URINARY TRACT INFECTIONS (UTIS) AFTER UROGENITAL PROCEDURES AND RELATED OUTCOMES AND COSTS: ANALYSIS OF DATA FROM THE NATIONAL HOSPITAL INFORMATION SYSTEM

The purpose of this study was to evaluate the proportion of Urinary Tract Infections (UTIs) after urogenital procedures and the associations between UTIs and in-hospital mortality, length of stay (LOS) and costs using the Hospital Information System of Italy. The National Hospital Discharge Database was retrospectively reviewed for all admissions between 2010 and 2014 with a urogenital procedure in the primary or secondary fields. UTIs were identified according to the presence of primary or secondary diagnosis of pyelonephritis; UTI, site not specified; other post-operative infections; other infections due to medical care; cystitis; and urethritis. The associations between the presence of a UTI and outcomes or costs were assessed with the Mann–Whitney unpaired test and Pearson's Chi-square test, when appropriate, and multivariable generalized linear models. A further sensitivity analysis was performed considering UTIs as only the presence of a primary or secondary diagnosis of a post-operative infection. Within the 5-year study period, we selected 272,133 acute admitted inpatients with a reported urogenital procedure; the proportion of admitted patients with UTIs was 7.0% (95% CI: 6.9% - 7.4%). The multivariate model showed no association between in-hospital mortality and the presence of a UTI (OR 0.95; 95% CI: 0.83 - 1.10) but indicated a strong association between in-hospital mortality and the diagnosis of a post-operative infection (OR 2.42; 95% CI: 1.26 - 4.66). Compared with patients without UTIs, those with UTIs had significantly longer hospital stays and mean hospitalization costs (IRRadj 1.50; 95% CI: 1.48 - 1.51 and βadj 1.19; 95% CI: 1.18 - 1.21, respectively). In this study we demonstrated that the presence of UTI after a urogenital procedure is associated with a prolonged hospital stay and elevated mean hospitalization costs. The study may help advance out understanding of the outcomes and costs related to UTIs after urogenital procedures in the Italian context.

Pyelonephritis in Pregnancy: Relationship of Fever and Maternal Morbidity.

Objective To evaluate the relationship between maternal fever at the time of hospital admission and subsequent maternal morbidity in pregnant patients with pyelonephritis. Study Design In this retrospective cohort study, inpatient records were reviewed for all obstetric patients discharged from a single tertiary care hospital between June 1, 2011, and May 30, 2017, with the diagnosis of pyelonephritis. Patients were stratified into two groups, those with and without fever at the time of admission. Descriptive statistics were utilized to evaluate the association of fever at the time of presentation with subsequent morbidity. Using admission vital signs, maternal early warning criteria (MEWC) were applied and odds ratios calculated to predict intensive care unit (ICU) admission. Results A total of 110 patients were admitted with pyelonephritis in pregnancy; 24 patients were febrile and 86 patients were afebrile on admission. There was no difference in rates of maternal ICU admission between both groups. Positive MEWC was predictive of ICU admission with an adjusted odds ratio of 16.54 (95% confidence interval: 1.29–212.5; p = 0.03). Conclusion Afebrile pregnant patients with pyelonephritis remain at risk of significant maternal morbidity. Application of the MEWC on admission identifies patients at higher risk of ICU admission.

Pyelonephritis: A Historical Reappraisal.

There is no human knowledge which cannot lose its scientific character when we forget the conditions under which it originated, the questions it answered and the function it was created to serve.[1][1] As with most diseases of the kidney, pyelonephritis is an old ailment, which as a diagnosis, is a

Diffusion weighted MR imaging in the diagnosis of acute pyelonephritis and its complications: A prospective observational study

Introduction: In diagnosing complicated pyelonephritis, imaging is essential for which traditionally computed tomography (CT) has been in use but in renal failure patients contrast enhanced CT can't be performed due to elevated serum creatine levels. This can be overcome with the help of Diffusion weighted (DW) magnetic resonance imaging (MRI). Purpose: To assess the morphological changes and signal abnormalities, in kidneys in patients with acute pyelonephritis (APN) on conventional MRI and DWI and to measure the ADC values in areas of abnormal signal intensity in DWI so as to differentiate between abscess and nephritis. Materials and Methods: In our study, 32 patients with clinical and laboratory diagnosis of pyelonephritis underwent conventional and Diffusion weighted MRI. Diffusion images were obtained by using a non-breath-hold, single-shot echo-planar sequence with b values of 50/400/800 s/mm2. Circular regions of interest were drawn in the areas of normal renal parenchyma, nephritis and abscesses. The ADC values of three tissue types were compared by using the paired t-test and ANOVA.P value Results: In our study, areas of normal renal parenchyma showed ADC values of (1.83 ± 0.06) × 10-3 mm2/s while areas of nephritis had ADC values of (1.20 ± 0.08) × 10-3 mm2/s which was significantly lower (P Conclusion: Diffusion weighted MR imaging is useful to diagnose abscess formation in patients with pyelonephritis without using IV contrast medium.

Candida albicans and tooth decay in children with pyelonephritis

Clinical investigations show that alongside Streptococcus m utans , a considerable concentration of Candida albicans is often found in the dental biofilm of toddlers suffering from early childhood caries. Based on some studies, the identification of Candida species in oral cavity is in positive correlation to poor oral hygiene status and abundant carbohydrate consumption. The caries-provoking potential of these species is associated with the acid-producing effect of their heterofermentative characteristics. Candida infection in the oral cavity may be a potential predictor of a tooth decay process in children. The aim of this study is to evaluate the interrelations between Candida albicans and caries in children with diagnosed pyelonephritis. In the investigation are included children with diagnosed pyelonephritis and healthy participants of the same age. Microbiological tests and epidemiological research are performed. Statistical methods are applied. In 4.17% of the patients with the diagnosis of pyelonephritis the test for the presence of Candida albicans in the oral cavity shows positive results. The Pearson`s correlation coefficient examining the indicators of Candida albicans and dft amounts to 0.215. There is a slight positive correlation between these indicators. It can be concluded that these microorganisms are not a definitive predisposing factor for initiation and progression of tooth decay among children with pyelonephritis and healthy controls.

Dopplerometric renal blood flow assessment in pregnant women with pyelonephritis

This article presents the results of searching for specific ultrasound criteria for diagnosis of pyelonephritis in pregnancy. The data obtained confirm low specificity of echographic criteria and show the possibilities of Doppler using in the diagnosis of pyelonephritis. (For citation: Khudovekova AM, Nagorneva SV, Prokhorova VS, Mozgovaya EV. Dopplerometric renal blood flow assessment in pregnant women with pyelonephritis. Journal of Obstetrics and Women’s Diseases. 2018;67(4):30-33. doi: 10.17816/JOWD67430-33).

Association of vesicoureteral reflux and renal scarring in urinary tract infections.

The aim was to investigate the relationship between vesicoureteral reflux (VUR) and renal damage in non-febrile, febrile for the first time and recurrent urinary tract infection (UTI) patients. The secondary aim was to determine whether C-reactive protein (CRP) in febrile UTIs could be a predictor of renal scarring. This prospective study included non-febrile, febrile for the first time and recurrent pediatric UTI cases. The routine lab analyses comprised a complete blood count, urea, creatinine, fully automated urinalysis, urine culture and CRP analyses. All the participants were examined using urine ultrasonography subsequent to their UTI diagnosis, voiding cystourethrography (VCUG) after six weeks and Tc-99m dimercaptosuccinic acid (DMSA) static renal scintigraphy after six months. There were included 47 children with non-febrile UTIs, 48 with first febrile UTIs and 61 with recurrent UTIs. A statistically significant difference was found among the groups in terms of VUR and renal scarring (p= 0.001 and p= 0.011, respectively). A statistically significant difference was also found in terms of renal scarring between patients with and without VUR (p= 0.001). Moreover, a statistically significant difference was also present in relation to renal scarring (p <0.05) in patients with five-fold lower or higher CRP values than the accepted cut-off value (5mg/dl). The ratio of renal scars detected was found to be parallel to the VUR frequency. The higher the VUR grade, the more renal damage was found. A positive correlation between elevated CRP and renal scarring was determined, indicating the presence of scarring during the diagnosis of pyelonephritis.
