Abstract Background: Febrile urinary tract infection (UTI) is one of the most common complications after ureteroscopic lithotripsy (URS). We evaluated the effect of secondary signs on preoperative computed tomography (CT) for febrile UTI after URS. Materials and methods: In total, 182 patients who underwent URS for ureteral stones from January 2013 to December 2015 were included in this study. These patients were divided into two groups according to the presence of postoperative febrile UTI after URS. We retrospectively compared the clinical factors, stone factors, and secondary signs between the groups. Predictive factors for febrile UTI after URS were analyzed using a multivariate logistic regression model. Results: Febrile UTI occurred in 26 of the 182 patients. In univariate analysis, presence of comorbid chronic kidney disease (CKD) and stone size were significantly different between UTI and non-UTI groups. Among secondary signs, presence of hydroureter, perinephric fat stranding, periureteral fat stranding, and tissue rim sign were significantly different between the groups. In multivariate logistic regression analysis, comorbid CKD, stone size, perinephric fat stranding, and tissue rim sign were independent predictive factors for febrile UTI after URS. Conclusion: This study demonstrated that secondary signs including perinephric fat stranding and tissue rim sign on preoperative CT, CKD, and stone size are independent predictive factors for febrile UTI after URS.

Obstructive Pyelonephritis

Background: Acute obstructive pyelonephritis due to urolithiasis represents a medico-surgical emergency that can lead to life-threatening complications. There are still no established factors that reliably predict progression toward acute pyelonephritis in patients presenting with a simple renal colic. Objective: To investigate clinical and paraclinical factors that are associated with the onset of acute obstructive pyelonephritis. Methods: Patients presenting to the emergency department for renal colic with obstructive urolithiasis on imaging were enrolled in the study. Demographic data, vital signs, medical comorbidities, blood test results, urinalysis, and radiological findings were recorded. Obstructive pyelonephritis was defined by the presence of two or more of the following criteria: fever, flank pain or costovertebral angle tenderness, and a positive urine culture. Results: Seventeen patients out of 120 presenting with renal colic, were diagnosed with acute obstructive pyelonephritis (14%). Parameters that were associated with the onset of obstructive pyelonephritis were: diabetes ( p = 0.03), elevated CRP ( p = 0.01), stone size (>5 mm) ( p = 0.03), dilatation of renal pelvis ( p = 0.01), peri-renal fat stranding ( p = 0.02), and positive nitrites on urinalysis ( p < 0.01). Hyperleukocytosis, acute kidney injury, multiple stones, pyuria (>10/mm3), hypertension, and were not associated with the onset of obstructive pyelonephritis. Conclusion: This study showed that known diabetic status, elevated CRP, positive urine nitrites, stone size (>5 mm), pyelic dilatation, and peri-renal fat stranding were associated with the onset of pyelonephritis in patients presenting to the emergency department with obstructive urolithiasis.

Background and ObjectiveTo compare the incidence of febrile urinary tract infection (UTI) and bacterial identification between patients with orthotopic neobladder (ONB) and ileal conduit (IC). Materials and MethodsData of 164 patients who underwent radical cystectomy with ONB and IC for bladder cancer between January 2009 and January 2018 at our institution were analyzed. Febrile UTI observed was listed and subsequently compared. Incidence of febrile UTI, clinicopathological characteristics, and microorganisms identified were reported at 3 months interval; and preoperative predictors of febrile UTI were evaluated with Cox regression analysis. Patients were divided into ONB and IC. ResultsThe study cohort included 52 patients with ONB and 112 patients with IC. Febrile UTI was diagnosed in 49 (29.9%) patients. Compared to IC group, ONB group had significantly higher incidence of young age (p=0.00), lower cancer stage (p=0.013), longer hospital stay (p=0.049), longer operation time (p=0.00), and higher incidence of febrile UTI within the first 3 months after surgery (p=0.006). On univariable and multivariable analysis, factors associated with significantly increased febrile UTI risk were diabetes (odds ratio [OR]: 4.52; p=0.002) and ONB diversion (OR: 1.27; p=0.031). Forty-four (89.8%) patients were culture positive. However, significant difference in microorganisms was not detected between patients who under-went ONB or IC diversion. ConclusionDiabetes and ONB diversion were associated with higher risk symptomatic UTI following radical cystectomy.

SummaryAim: This study is aimed to evaluate the predictive value of the neutrophil-to-lymphocyte ratio (NLR) for cortical defect on initial and follow-up Tc-99m dimercaptosuccinic acid (DMSA) scan in children with the first febrile urinary tract infection (UTI). Methods: We retrospectively enrolled 179 children with the first febrile UTI who underwent DMSA scan and laboratory tests. In patients with abnormal DMSA scan findings, follow-up DMSA scan was performed at least 6 months after the initial scan. All DMSA scans were classified as negative and positive cortical defects. Multiple logistic regression analyses were performed to identify the risk factors for cortical defect on initial and follow-up DMSA scan. Results: Cortical defects on initial DMSA scan were noted in 133 patients. Vesicoureteral reflux (VUR), white blood cell count, absolute neutrophil count, NLR, and serum C-reactive protein level were independent predictive factors for positive cortical defect on initial DMSA scan (p < 0.050). On follow-up DMSA scan, 24 of the 133 patients showed persistent cortical defects, and only VUR was significantly associated with persistent cortical defect (p = 0.002). In 84 patients who showed cortical defect on initial scan and absence of VUR, only NLR was significantly associated with persistent cortical defect on follow-up scan (p = 0.025). Conclusion: NLR was significantly associated with persistent cortical defect on follow-up DMSA scan in patients without VUR, as well as positive cortical defect on initial scan.
