Abstract
OBJECTIVE To emphasize preventive measures and outline management strategies for inadvertent ureteral cannulation. METHODS We present a case report and conduct a literature review of 39 case reports on ureteral cannulation, examining a total of 48 patients. RESULTS About 67% of the cases were female, and long-term catheterization was observed in 67% of the cases. Neurological conditions such as spinal cord injury (SCI), stroke, dementia, multiple sclerosis, and myasthenia gravis were the primary factors (48%) in ureteral cannulation. Symptoms included flank pain (46%), fever (31%), oliguria (27%), non-deflatable balloon issues (25%), hematuria (21%), abdominal pain (17%), urine leak (12.5%), and nausea/vomiting (8%). Complications varied, including acute pyelonephritis (35%), acute kidney injury (27%), urosepsis (21%), and ureter rupture (17%). Despite inadvertent catheter placement, 25% of patients had no complications. More than half of the patients (58%) were managed through catheter change, while 27% underwent cysto-ureteroscopy with or without balloon puncture or ureteral stenting. Additionally, 10% received interventional radiology procedures, 6.25% underwent surgical repair, and 4% underwent ultrasound-guided balloon puncture. CONCLUSIONS Female gender, neurologic conditions, and long-term catheterization were identified as predominant risk factors. Early detection of ureteral cannulation can prevent severe complications, particularly in certain special populations such as patients with neurogenic bladder or SCI, who may have reduced sensation and expression capabilities.

Abstract
Background: To investigate retrospectively whether metabolic syndrome (MetS) of flexible ureteroscopy (fURS) lithotripsy can be used to predict post-operative infection. Patients and Methods: After screening, 1,110 patients who received fURS lithotripsy for upper urinary tract stones in our center between January 2015 and December 2022 were analyzed retrospectively. Patients were divided into MetS-positive group and MetS-negative group. Post-operative infection was divided into fever, urosepsis, and septic shock. Relevant data during the peri-operative period were collected. Univariable and multivariable logistic regression analyses were adopted to estimate the impact of metabolic syndrome on post-operative infection in patients undergoing fURS lithotripsy. Results: Among the 1,110 patients, 427 tested positive for MetS, whereas 683 tested negative. Eighty-eight patients suffered from fever (67 patients in the MetS-positive group and 21 in the MetS-negative group). Forty-nine patients had urosepsis (29 patients in the MetS-positive group and 20 in the MetS-negative group), of whom seven patients developed septic shock. No patient developed multiple organ failure or died because of infection. The prevalence of post-operative infections in the MetS-positive group was higher than that in the MetS-negative group (p < 0.001). Multivariable logistic regression analyses showed that diabetes mellitus, MetS-positive, positive urine culture, and longer operation time were positively correlated with post-operative fever. Positive MetS, positive urine culture, and longer operation time were strongly correlated with post-operative urosepsis. Conclusions: Metabolic syndrome was found to be associated with post-operative infection in patients undergoing fURS lithotripsy, suggesting it can serve as a predictive factor.

Abstract
Introduction Ureteroscopic lithotripsy (URSL) is an approved, minimally invasive, low-risk procedure for urolithiasis treatment. However, some patients may develop urinary tract infection (UTI) post-procedure, eventually leading to urosepsis. Determining the predictors of infection after URSL would help identify patients at a high risk of urosepsis, thereby enabling the early implementation of effective treatment. Therefore, we aimed to establish the incidence and predictors of urosepsis after URSL. Material and methods We assessed 231 patients who underwent URSL using a holmium laser. The incidence of urosepsis during the 30-day post-treatment period was analysed, and potential predictors of urosepsis, including patient characteristics and individual clinical factors, were examined. Results Statistical analysis revealed that 16.88% of patients had a confirmed positive urine culture before the procedure. Post-procedure urosepsis occurred in 4.76% of patients. Univariable analysis revealed that 3 factors were significantly associated with the risk of postoperative urosepsis: double-J stent insertion before URSL, pre-operative positive urine culture, and MDR pathogen found preoperatively. In multivariable analysis, only positive urine culture remained significantly associated with the risk of urosepsis after URSL. Conclusions Patients with positive urine culture before URSL are at significantly higher risk of urosepsis in the postoperative period. Hence, urine culture should be routinely performed before planned endoscopic urolithiasis treatment.

Abstract
Background Urosepsis is a common disease in urology, which is characterized by high treatment costs and high mortality. In the treatment of sepsis, anti-infection therapy is the most important means. However, the effect of empirical anti-infection therapy is often not ideal. Therefore, it is necessary to continuously monitor the prevalence of bacterial isolates in the blood culture of patients with urinary sepsis and their sensitivity to antibacterial drugs. This is of great significance to improve the efficacy of empirical antibiotic therapy for urosepsis. Objective To elucidate the landscape of prevailing bacterial profiles and their antimicrobial susceptibilities in urosepsis cases, and to furnish robust clinical evidence to underpin the timely initiation of empirical antibiotic treatment. Methods Collect the basic information and blood culture results of patients with urosepsis hospitalized from 2017 to 2020. Retrospective analysis of bacterial species and antimicrobial susceptibility in urosepsis and changes over 4 years. Results Gram-negative bacteria (178 isolates, 75.11%) constituted the main pathogens causing urosepsis, followed by Gram-positive bacteria (46 isolates, 19.41%) and fungus (13 isolates, 5.48%). The sensitivity of ertapenem, meropenem, amikacin, and imipenem to Gram-negative bacteria all exceeded 85%. The sensitivity rates of levofloxacin, gentamicin, and ciprofloxacin are decreasing every year (p < 0.05). Tigecycline, vancomycin, and linezolid exhibited excellent sensitivity against Gram-positive bacteria. Among fungi, fluconazole demonstrated universal sensitivity, while itraconazole-resistant isolates have been found, and amphotericin B is still effective. Conclusion Analysis of blood culture results of patients more accurately reflected the etiology of urosepsis, mainly Escherichia coli, Enterococcus, and Klebsiella pneumoniae. If there are no definitive blood culture results, empiric treatment of urosepsis should not include fluoroquinolone antibiotics. Cefepime, cefoxitin, and ceftazidime are the most sensitive antibiotics to Gram-negative bacteria besides carbapenem antibiotics. In addition, the current situation regarding extended-spectrum β-lactamase-producing bacteria and carbapenem-resistant Enterobacteriaceae bacteria resistance is extremely concerning with limited therapeutic options available. Strengthening antibiotic management practices and exploring novel antibacterial agents can help mitigate this issue.

Abstract
Background and Objectives: Urinary tract infections (UTIs) are an important cause of perinatal and maternal morbidity and mortality. The aim of this study was to describe and compare the main pregnancy outcomes among pregnant patients with complicated and uncomplicated UTIs; Materials and Methods: This retrospective study included 183 pregnant patients who were evaluated for uncomplicated UTIs and urosepsis in the Urology Department of 'C.I. Parhon' University Hospital, and who were followed up at a tertiary maternity hospital-'Cuza-voda' from Romania between January 2014 and October 2023. The control group (183 patients) was randomly selected from the patient's cohort who gave birth in the same time frame at the maternity hospital without urinary pathology. Clinical and paraclinical data were examined. Descriptive statistics and a conditional logistic regression model were used to analyze our data. Results: Our results indicated that patients with urosepsis had increased risk of premature rupture of membranes (aOR: 5.59, 95%CI: 2.02-15.40, p < 0.001) and preterm birth (aOR: 2.47, 95%CI: 1.15-5.33, p = 0.02). We could not demonstrate a statistically significant association between intrauterine growth restriction and pre-eclampsia with the studied urological pathologies. Conclusions: Careful UTI screening during pregnancy is needed for preventing maternal-fetal complications.

Abstract
OBJECTIVE Patients with ureteral calculi and systemic inflammatory response syndrome (SIRS) often require emergency drainage, and percutaneous nephrostomy (PCN) and retrograde ureteral stent insertion (RUSI) are the most commonly used methods. Our study aimed to identify the best choice (PCN or RUSI) for these patients and to examine the risk factors for progression to urosepsis after decompression. METHODS A prospective, randomized clinical study was performed at our hospital from March 2017 to March 2022. Patients with ureteral stones and SIRS were enrolled and randomized to the PCN or RUSI group. Demographic information, clinical features and examination results were collected. RESULTS Patients (n = 150) with ureteral stones and SIRS were enrolled into our study, with 78 (52%) patients in the PCN group and 72 (48%) patients in the RUSI group. Demographic information was not significantly different between the groups. The final treatment of calculi was significantly different between the two groups (p < .001). After emergency decompression, urosepsis developed in 28 patients. Patients with urosepsis had a higher procalcitonin (p = .012) and blood culture positivity rate (p < .001) and more pyogenic fluids during primary drainage (p < .001) than patients without urosepsis. CONCLUSION PCN and RUSI were effective methods of emergency decompression in patients with ureteral stone and SIRS. Patients with pyonephrosis and a higher PCT should be carefully treated to prevent the progression to urosepsis after decompression.Key messageIn this study, we evaluate the best choice (PCN or RUSI) for patients who have ureteral stones and SIRS and to examine the risk factors for progression to urosepsis after decompression. This study found that PCN and RUSI were effective methods of emergency decompression. Pyonephrosis and higher PCT were risk factors for patients to develop to urosepsis after decompression.

Abstract
Background and Objectives: Urosepsis is a significant cause of maternal and fetal mortality. While certain risk factors for urinary tract infections (UTIs) in pregnant women are well established, those associated with an elevated risk of urosepsis in pregnant women with upper UTIs remain less defined. This study aims to identify factors linked to an increased risk of urosepsis and examine urologic treatment outcomes in such cases. Materials and Methods: We conducted a retrospective analysis on 66 pregnant women diagnosed with urosepsis over a nine-year period. A control group included 164 pregnant women with upper UTIs, excluding urosepsis, admitted during the same timeframe. This study highlights factors potentially contributing to urosepsis risk, including comorbidities like anemia, pregnancy-related hydronephrosis or secondary to reno-ureteral lithiasis, prior UTIs, coexisting urological conditions, and urologic procedures. Outcomes of urologic treatments, hospitalization duration, obstetric transfers due to fetal distress, and complications associated with double-J catheters were analyzed. Results: Pregnant women with urosepsis exhibited a higher prevalence of anemia (69.7% vs. 50.0%, p = 0.006), 2nd-3rd grade hydronephrosis (81.8% vs. 52.8%, p = 0.001), and fever over 38 °C (89.4% vs. 42.1%, p = 0.001). They also had a more intense inflammatory syndrome (leukocyte count 18,191 ± 6414 vs. 14,350 ± 3860/mmc, p = 0.001, and C-reactive protein (CRP) 142.70 ± 83.50 vs. 72.76 ± 66.37 mg/dL, p = 0.001) and higher creatinine levels (0.77 ± 0.81 vs. 0.59 ± 0.22, p = 0.017). On multivariate analysis, factors associated with increased risk for urosepsis were anemia (Odds Ratio (OR) 2.622, 95% CI 1.220-5.634), 2nd-3rd grade hydronephrosis (OR 6.581, 95% CI 2.802-15.460), and fever over 38 °C (OR 11.612, 95% CI 4.804-28.07). Regarding outcomes, the urosepsis group had a higher rate of urological maneuvers (87.9% vs. 36%, p = 0.001), a higher rate of obstetric transfers due to fetal distress (22.7% vs. 1.2%, p = 0.001), and migration of double-J catheters (6.1% vs. 0.6%, p = 0.016), but no maternal fatality was encountered. However, they experienced the same rate of total complications related to double-J catheters (19.69% vs. 12.80%, p > 0.05). The pregnant women in both groups had the infection more frequently on the right kidney, were in the second trimester and were nulliparous. Conclusions: Pregnant women at increased risk for urosepsis include those with anemia, hydronephrosis due to gestational, or reno-ureteral lithiasis, and fever over 38 °C. While the prognosis for pregnant women with urosepsis is generally favorable, urological intervention may not prevent a higher incidence of fetal distress and the need for obstetric transfers compared to pregnant women with uncomplicated upper UTIs.

Abstract
Background and Objectives. Numerous studies have been conducted to explore the epidemiological characteristics of urinary tract infections (UTI) and sepsis. However, there is still a lack of relevant bacteriological features and prognostic information regarding urosepsis based on bacteriological etiology. The current study aims to evaluate the bacterial etiology of complicated UTI (cUTI) and bacterial resistance to antibiotics and whether they present an intrinsic risk of developing urosepsis. Materials and Methods. A retrospective study was performed that included 102 patients who were diagnosed with cUTI and admitted to the urology department of the "Sfântul Apostol Andrei" County Emergency Clinical Hospital (GCH) from September 2019 to May 2022. Results. A considerable number of patients, n = 41 (40.2%), were diagnosed with multi drug-resistant (MDR) infection. Escherichia coli (E. coli) was identified as the prevailing pathogen, accounting for 51 patients. Klebsiella manifested itself as the subsequent causative agent in 27 instances. The presence of Enterococcus spp. infection was documented in 13 patients, whereas Pseudomonas emerged as the etiological perpetrator in the clinical context of 8 patients. The current study found a substantial prevalence of resistance to first-line antibiotics. The overall resistance rate was 74.5% for penicillin, 58.82% for trimethoprim-sulfamethoxazole and 49% for fluoroquinolones; cephalosporin resistance displayed an inverse correlation with antibiotic generation with fourth-generation cephalosporins exhibiting a resistance rate of 24.5%, and first-generation cephalosporins demonstrating a resistance rate of 35.29%. Conclusions. Age, comorbidities and indwelling urinary catheters are risk factors for developing MDR infections. While the intrinsic characteristics of the causative bacterial agent in cUTI may not be a risk factor for developing urosepsis, they can contribute to increased mortality risk. For empiric antibiotic treatment in patients with cUTI who are at a high risk of developing urosepsis and experiencing a potentially unfavorable clinical course, broad-spectrum antibiotic therapy is recommended. This may include antibiotics, such as amikacin, tigecycline, carbapenems and piperacillin-tazobactam.

Abstract
Urinary tract infections are the most common bacterial infections encountered by health care professionals. In women, the lifetime incidence of urinary tract infections may be up to 40% to 50%, of whom a further 40% may have recurrent infections. Urinary tract infections are associated with significant morbidity and potential mortality-they may be complicated by frequent recurrences, kidney damage, sepsis, and preterm birth, as well as collateral damage of antimicrobial use, which includes Clostridium difficile colitis and selection of drug-resistant organisms. There are personal costs such as reduced quality of life in patients affected by recurrent urinary tract infections, and societal impacts resulting from absenteeism and health care costs. In this review, we discuss the definitions and classifications, pathogenesis, and current principles of management and prevention of urinary tract infections.

Abstract
Although rare, colo-renal fistulas pose diagnostic challenges due to their varied presentations and etiologies. Here, we present a unique case of a woman with recurrent pyelonephritis, severe anemia, and unintended weight loss, who was eventually diagnosed with a colo-renal fistula. Delayed imaging following intraoperative fluoroscopy revealed the abnormal connection between the colon and upper urinary tract. The patient underwent nephrectomy and colon resection. This case report emphasizes the need for suspicion in diagnosing such fistulas and highlights their varied management. This case adds to the literature by illustrating an unusual presentation and underscores the complexity of diagnosis and treatment.

Abstract
Extracellular DNA (ecDNA) is a promising candidate marker for the early diagnosis and monitoring of urinary tract infections (UTIs). The aim of our study is to describe the dynamics of ecDNA in the plasma and urine of patients with urosepsis as well as in a mouse model of UTI. Samples of blood and urine were collected from adult patients with UTIs and obstructive uropathy (n = 36) during the first 3 days at the hospital and during a follow-up. Bacterial burden and urinary ecDNA were evaluated in a mouse UTI model (n = 26) at baseline; 24, 48, and 72 h after UTI induction; and 7 days after UTI induction. The plasma ecDNA did not change during urosepsis, but the plasma DNase activity increased significantly at the follow-up. The urinary ecDNA decreased significantly during hospitalization and remained low until the follow-up (90% lower vs. admission). No change was seen in the urinary DNase activity. C-reactive protein (CRP) and procalcitonin are positively correlated with plasma and urinary ecDNA. A UTI caused sepsis in 23% of mice. The urinary ecDNA decreased by three-fold and remained low until day 7 post-infection. Urinary bacterial burden is correlated with urinary ecDNA. Urinary ecDNA is a potential non-invasive marker for monitoring the effects of treatment during urosepsis and is related to UTI progression in the experimental animal model.

Abstract
Background. The study aimed to assess whether the eradication of kidney stones might result in a substantial reduction in the onset of recurrent UTIs. Methods. We selected all the patients who underwent ureteroscopy (URS) for stone disease between 2012 and 2021, with either a history of recurrent UTIs (rUTIs), urosepsis or pre-operative positive urine culture (UC). Data included patient demographics, microbiological data, stone parameters, stone-free and infection-free rates (SFR and IFR, respectively) at follow-up, defined as fragments <2 mm at imaging and the absence of symptoms and urine-culture-proven UTI. Results. Overall, 178 patients were selected. The median age was 62 years. The median cumulative stone size was 10 mm (7-17.25), and the commonest locations were the lower pole (18.9%) and proximal ureter (14.9%). The overall stone-free rate at follow-up was 89.3%. The IFR at 3 months was 88.3%. As follow-up duration increased, the IFR reduced to 85.4%, 74.2%, 68% and 65% at 6, 12, 18 and 24 months, respectively. Patients who had infection recurrence were more likely to present stone persistence or recurrence compared to those who were infection-free at follow-up (20% vs. 4.4%, p = 0.005). Conclusions. SFR after URS is a significant predicting variable for the likelihood of infection-free status at follow-up in patients with an rUTI or positive UC at the time of URS.

Abstract
INTRODUCTION The procedure of percutaneous nephrolithotomy (PCNL) is considered a minimally invasive method for removing stones from the kidneys or ureters. PCNL can cause a wide range of complications, such as urosepsis, a rare but serious complication. METHODS A retrospective cohort study of patients who underwent PCNL from the period 2016 to 2022 was conducted at King Abdulaziz Medical City. Data were collected by chart review using the BestCARE system. SPSS version 23 (IBM Corporation, Armonk, NY, USA) was used. Qualitative variables were expressed as percentages and frequencies. The chi-square test was used to compare the qualitative variables. The K-S test was used to check the normality of the data. Quantitative variables were compared between groups using the independent sample t-test and the nonparametric Mann-Whitney test. Fisher's exact test was used to compare categorical variables. RESULTS A total of 155 patients were included in this study. The mean age of the participants overall was found to be 49. About 108 (69.7%) of the participants were male. Regarding risk factors for urosepsis, diabetes mellitus was found in 54 (34.8%) of the participants. The incidence of urosepsis following PCNL was found to be 3 (1.9%) of the patients. The most frequently reported indication was found to be unilateral renal stones. The most frequently reported type of stone in the analysis was found to be calcium oxalate in nearly two-thirds 98 (63.2%) of the patients. CONCLUSION The incidence of urosepsis among the patients who underwent PCNL was less than 2%. Diabetes mellitus, followed by hypertension, were the most prevalent co-morbidities among the participants. Cefuroxime was the antibiotic of choice when treating patients and following urosepsis.

Abstract
Murine sepsis models are typically polymicrobial, and are associated with high mortality. We aimed to develop a high-throughput murine model that mimics a slow-paced, monomicrobial sepsis originating from the urinary tract. A total of 23 male C57Bl/6 mice underwent percutaneous insertion of a 4 mm catheter into the bladder using an ultrasound-guided method, previously developed by our group. The following day, Proteus mirabilis (PM) was introduced percutaneously in the bladder in three groups: g1-50 µL 1 × 108 CFU/mL solution (n = 10); g2-50 µL 1 × 107 CFU/mL solution (n = 10); and g3 (sham mice)-50 µL sterile saline (n = 3). On day 4, mice were sacrificed. The number of planktonic bacteria in urine, adherent to catheters, and adherent to/invaded into the bladder and spleen was assessed. Cell-free DNA, D-dimer, thrombin-antithrombin complex (TAT), and 32 pro-/anti-inflammatory cytokines/chemokines were quantified in the blood. All mice survived the 4 day postinterventional period. Mean weight loss was 11% in g1, 9% in g2, and 3% in the control mice. Mean urine CFU counts were highest in group 1. All catheters showed high catheter-adhered bacterial counts. Of the infected mice, 17/20 had CFU counts in the splenic tissue, indicating septicemia. Plasma levels of cell-free DNA, D-dimer, and the proinflammatory cytokines IFN-γ, IL-6, IP-10, MIG, and G-CSF were significantly elevated in infected mice versus controls. We present a reproducible, monomicrobial murine model of urosepsis that does not lead to rapid deterioration and death, and is useful for studying prolonged urosepsis.

Abstract
Children with recurrent fevers in a short period of time need to be worked up to identify the underlying cause. Fevers in children and infants can be from many different sources. Vesicoureteral reflux (VUR) is an anatomical and physiological anomaly in children that can lead to retrograde urine flow from the bladder back into the distal ureters. This retrograde flow can cause distention, scarring, and recurrent infections including urinary tract infections (UTIs) and pyelonephritis. Identification of multiple UTIs in a short period of time should raise suspicion for a more complex pathology such as VUR and requires a more thorough workup. This workup is needed for both diagnosis and treatment. The patient in this report was seen by physicians in the emergency department, pediatric intensive care unit, nephrology, and her pediatrician. If surgery is needed, a urologist would also be involved. This report will discuss the pathophysiology of VUR and associated pathologies, diagnostic approach, medical and surgical treatment modalities, as well as prognosis.

Abstract
OBJECTIVES Early recognition and timely intervention for urosepsis are key to reducing morbidity and mortality. Blood culture has low sensitivity, and a long turnaround time makes meeting the needs of clinical diagnosis difficult. This study aimed to use biomarkers to build a machine learning model for early prediction of urosepsis. METHODS Through retrospective analysis, we screened 157 patients with urosepsis and 417 patients with urinary tract infection. Laboratory data of the study participants were collected, including data on biomarkers, such as procalcitonin, D-dimer, and C-reactive protein. We split the data into training (80%) and validation datasets (20%) and determined the average model prediction accuracy through cross-validation. RESULTS In total, 26 variables were initially screened and 18 were statistically significant. The influence of the 18 variables was sorted using three ranking methods to further determine the best combination of variables. The Gini importance ranking method was found to be suitable for variable filtering. The accuracy rates of the six machine learning models in predicting urosepsis were all higher than 80%, and the performance of the artificial neural network (ANN) was the best among all. When the ANN included the eight biomarkers with the highest influence ranking, its model had the best prediction performance, with an accuracy rate of 92.9% and an area under the receiver operating characteristic curve of 0.946. CONCLUSIONS Urosepsis can be predicted using only the top eight biomarkers determined by the ranking method. This data-driven predictive model will enable clinicians to make quick and accurate diagnoses.

Abstract
INTRODUCTION AND OBJECTIVES The use of ureteral access sheaths (UAS) limits the irrigation-induced increase in intrarenal pressure during ureteroscopy (URS). We investigated the relationship between UAS and rates of postoperative infectious complications in stone patients treated with URS. MATERIALS AND METHODS Data from 369 stone patients treated with URS from September 2016 to December 2021 at a single institution were analyzed. UAS (10/12 Fr) placement was attempted in case of intrarenal surgery. The chi-square test was used to assess the relationship between the use of UAS and fever, sepsis, and septic shock. Univariable and multivariable logistic regression analyses tested the association of patients' characteristics and operative data and the rate of postoperative infectious complications. RESULTS Full data collection of 451 URS procedures was available. Overall, UAS was used in 220 (48.8%) procedures. As for postoperative infectious sequalae, we recorded fever (n = 52; 11.5%), sepsis (n = 10; 2.2%), and septic shock (n = 6; 1.3%). Of those, UAS was not used in 29 (55.8%), 7 (70%), and 5 (83.3%) cases, respectively (all p > 0.05). At multivariable logistic regression analysis, performing URS without UAS was not associated with the risk of having fever and sepsis, but it increased the risk of septic shock (OR = 14.6; 95% CI = 1.08-197.1). Moreover, age-adjusted CCI score (for fever-OR = 1.23; 95% CI = 1.07-1.42, sepsis-OR = 1.47; 95% CI = 1.09-1.99, and septic shock-OR = 1.61; 95% CI = 1.08-2.42, respectively), history of fever secondary to stones (for fever-OR = 2.23; 95% CI = 1.02-4.90) and preoperative positive urine culture (for sepsis-OR = 4.87; 95% CI = 1.12-21.25) did emerge as further associated risk factors. CONCLUSIONS The use of UAS emerged to prevent the onset of septic shock in patients treated with URS, with no clear benefit in terms of fever and sepsis. Further studies may help clarify whether the reduction in fluid reabsorption load mediated by UAS is protective against life-threatening conditions in case of infectious complications. The patients' baseline characteristics remain the main predictors of infectious sequelae in a clinical setting.

Abstract
Urosepsis is sepsis caused by urogenital tract infection and is one of the most common critical illnesses in urology. If urosepsis is not diagnosed early, it can rapidly progress and worsen, leading to increased mortality. In recent years, with the increase of urinary tract surgery, the incidence of urosepsis continues to rise, posing a serious threat to patients. Early diagnosis of urosepsis, timely and effective treatment can greatly reduce the mortality of patients. Biomarkers such as WBC, NLR, PCT, IL-6, CRP, lactate, and LncRNA all play specific roles in the early diagnosis or prognosis of urosepsis. In addition to the abnormal increase of WBC, we should be more alert to the rapid decline of WBC. NLR values were superior to WBC counts alone in predicting infection severity. Compared with several other biomarkers, PCT values can differentiate between bacterial and non-bacterial sepsis. IL-6 always has high sensitivity and specificity for the diagnosis of sepsis, and CRP also has high sensitivity and specificity for the diagnosis of urosepsis. Lactic acid is closely related to the prognosis of patients with urosepsis. LncRNAs may be potential biomarkers of urosepsis. This article summarizes the main biomarkers, hoping to provide a reference for the timely diagnosis and evaluation of urosepsis.

Abstract
Despite extensive research, urosepsis remains a life-threatening, high-mortality disease. Currently, animal models of urosepsis widely accepted by investigators are very scarce. This study aimed to establish a standardized and reproducible model of urosepsis in rats. Forty adult Wistar rats were randomly divided into four groups according to the concentration of injected E. coli suspensions: Sham, Sep 3×, Sep 6×, and Sep 12×. Because the ureter is so thin and fragile, no conventional needle can be inserted into the ureter, which is probably why rats are rarely used to develop models of urosepsis. To solve this problem, the left ureter was ligated in the first procedure. After 24 hours, the left ureter above the ligation was significantly dilated, then saline or different concentrations of E. coli at 3 ml/kg were injected into the left renal pelvis using a 30G needle. The left ureter was subsequently ligated again at a distance of 1 cm from the renal hilum to maintain high pressure in the renal pelvis. Following injection of E. coli or saline for 24 h, three rats from each group were sacrificed and their organs (lung, liver, and right kidney) were collected. In contrast, the remaining seven rats continued to be observed for survival. At 10 days after E. coli injection, rats in the sep12× group had a higher mortality rate (100%) compared to the sep3× group (28.6%) or the sep6× group (71.4%). The significant changes in peripheral blood WBC count, serum IL-6 and TNF-α levels were also in the sep12× group. In addition, rats in the sepsis group showed multi-organ dysfunction, including damage to the lungs, liver, and kidneys. The establishment of a standardized rat model of urosepsis may be of great value for studying the pathophysiological of urosepsis.

Abstract
Escherichia coli is a versatile commensal and pathogenic member of the human microflora. As the primary causative pathogen in urosepsis, E. coli places an immense burden on healthcare systems worldwide. To further exacerbate the issue, multi drug resistance (MDR) has spread rapidly through E. coli populations, making infections more troublesome and costlier to treat. This paper aimed to review the literature concerning the development of MDR in uropathogenic E. coli (UPEC) and explore the existing evidence of current and emerging treatment strategies. While some MDR strains maybe treated with β-lactam-β-lactamase inhibitor combinations as well as cephalosporins, cephamycin, temocillin and fosfomycin, current treatment strategies for many MDR UPEC strains are reliant on carbapenems. Carbapenem overreliance may contribute to the alarming dissemination of carbapenem-resistance amongst some UPEC communities, which has ushered in a new age of difficult to treat infections. Alternative treatment options for carbapenem resistant UPEC may include novel β-lactam-β-lactamase or carbapenemase inhibitor combinations, cefiderocol, polymyxins, tigecycline, aminoglycosides or fosfomycin. For metallo-β-lactamase producing strains (e.g., NDM, IMP-4), combinations of cefazidime-avibacam with aztreonam have been used. Additionally, the emergence of new antimicrobials brings new hope to the treatment of such infections. However, continued research is required to successfully bring these into the clinic for the treatment of MDR E. coli urosepsis.

Abstract
INTRODUCTION About 200 thousand operations for urolithiasis are performed annually in Russia, but the frequency of postoperative complications reaches 30%. Infectious complications occur with a frequency of up to 40% in the form of various forms of pyelonephritis, urosepsis is recorded in 3% of patients. The aim of the study determine the intensity of blebbing of the plasma membrane of lymphocytes in infectious complications of urolithiasis. MATERIALS AND METHODS A prospective study examined 1,240 patients with urolithiasis. Inflammatory complications were characterized by the development of bacteriuria, serous pyelonephritis, purulent pyelonephritis and urosepsis. Complications of infectious nature were characterized by the development of bacteriuria, serous pyelonephritis, purulent pyelonephritis and urosepsis. During the study, complications of an infectious nature were detected in 148 patients, which amounted to 11,93% of cases. The control group consisted of - 25 persons with urolithiasis and a favorable course of the postoperative period. Lymphocyte membrane condition was evaluated by phase contrast microscopy. RESULTS Changes in plasma membrane structure were more frequently reported in patients with postoperative purulent pyelonephritis and urosepsis. When assessing the presence of circulating microparticles, the highest number was recorded in patients with urolithiasis complicated by purulent pyelonephritis or urosepsis - 1318 [982; 2007] and 1531 [1028; 1963], respectively. A relationship was established between the degree of severity of terminal blebbing of the plasma membrane of lymphocytes and the nature of inflammatory complications in urolithiasis.

Abstract
Aims: We characterize the epidemiology of Actinotignum schaalii within a large Canadian region after implementation of improved identification methods. Patients & methods: Positive cultures for A. schaalii from a centralized microbiology laboratory in Canada were analyzed. Clinical data were retrieved through administrative databases and chart reviews. Primary outcome was incidence of A. schaalii infections; secondary outcomes included mortality, hospital admission and length of stay. Results & conclusions: 86 unique isolates were studied, 37 bloodstream infections (BSI) and 49 non-BSIs. Patients with BSIs were older with more comorbidities, with urinary tract infections implicated as the most frequent source; skin abscesses caused the most non-BSIs. Hospitalization and 90-day mortality was higher in the BSI group. A. schaalii is an important community-acquired pathogen with the potential to cause invasive infections.

Abstract
Carbapenems are recommended for the treatment of urosepsis caused by extended-spectrum β-lactamase (ESBL)-producing, multidrug-resistant Escherichia coli; however, due to selection of carbapenem resistance, there is an increasing interest in alternative treatment regimens including the use of β-lactam-aminoglycoside combinations. We compared the pharmacodynamic activity of piperacillin-tazobactam and amikacin as mono and combination therapy versus meropenem monotherapy against extended-spectrum β-lactamase (ESBL)-producing, piperacillin-tazobactam resistant E. coli using a dynamic hollow fiber infection model (HFIM) over 7 days. Broth-microdilution was performed to determine the MIC of E. coli isolates. Whole genome sequencing was conducted. Four E. coli isolates were tested in HFIM with an initial inoculum of ~107 CFU/mL. Dosing regimens tested were piperacillin-tazobactam 4.5 g, 6-hourly, plus amikacin 30 mg/kg, 24-hourly, as combination therapy, and piperacillin-tazobactam 4.5 g, 6-hourly, amikacin 30 mg/kg, 24-hourly, and meropenem 1 g, 8-hourly, each as monotherapy. We observed that piperacillin-tazobactam and amikacin monotherapy demonstrated initial rapid bacterial killing but then led to amplification of resistant subpopulations. The piperacillin-tazobactam/amikacin combination and meropenem experiments both attained a rapid bacterial killing (~4-5 log10) within 24 h and did not result in any emergence of resistant subpopulations. Genome sequencing demonstrated that all ESBL-producing E. coli clinical isolates carried multiple antibiotic resistance genes including blaCTX-M-15, blaOXA-1, blaEC, blaTEM-1, and aac(6')-Ib-cr. These results suggest that the combination of piperacillin-tazobactam/amikacin may have a potential role as a carbapenem-sparing regimen, which should be tested in future urosepsis clinical trials.

Abstract
Background Urosepsis is an acute life-threating disease, and some cases show refractory outcome to therapy. In an aging society of developed countries, characteristics of urosepsis are becoming complicated. We performed a comprehensive investigation regarding the clinical and social aspects that are related to refractory outcomes in urosepsis patients. Methods The patient cohort consisted of 66 patients with urosepsis. Multiple factors from clinical and social aspects were reviewed retrospectively. Two categories of refractory outcomes were defined. One was afebrile resistance (AR); fever continued more than 7 days from the initiation of therapy. Another was discharge resistance (DR); hospitalization continued for more than 30 days. Logistic regression analyses were performed to identify significant factors that are related to the AR or DR. Results Univariate analysis demonstrated that high score of Eastern Cooperative Oncology Group Performance Status (ECOG PS) (≥ 2) and Age-adjusted Charlson comorbidity index (CCI) (≥ 4), high serum C-reactive protein (CRP) level (≥ 14.9 mg/dL), and low serum albumin level (≤ 2.26 g/dL) were significantly related to AR. Univariate analysis results also revealed that high score of ECOG PS (≥ 2), high serum creatinine level (≥ 1.54 mg/dL) and vasopressor administration were significantly related to DR. Multivariate analyses demonstrated that low serum albumin level (≤ 2.26g/dL) was the only significant factor that was related to AR. In contrast, high score of ECOG PS (≥ 2) and high serum creatinine level (≥ 1.54 mg/dL) were significant factors that were related to DR. Conclusion It is suggested that evaluating serum albumin levels is essential for the therapeutic first step because hypoalbuminemia was the significant factor that was related to obstruction to antipyresis. It is also suggested that the deterioration of patients' activities of daily living and renal dysfunction might be the refractory factors for discharge from the hospital, which was the ultimate therapeutic goal.

Abstract
Septic aneurysms of the pulmonary artery are rare conditions, with few cases having been reported worldwide. They are assumed to result from septic emboli that cause a local inflammatory reaction of the arterial wall, ultimately leading to degenerative changes. We report the case of a 63-year-old female patient presenting with Klebsiella pneumoniae urosepsis and first diagnosis of diabetes mellitus, who developed a life-threatening infectious pulmonary artery aneurysm secondary to bacteremia with Klebsiella pneumoniae. The patient required a lobectomy due to pulmonary hemorrhage. We review the clinical hallmarks of Klebsiella pneumoniae related septic pulmonary embolic disease and summarize currently known risk factors for the development of infectious aneurysmatic disease including diabetes mellitus and other states of immunosuppression. The featured case aims to increase the awareness for this seldom but life-threatening complication of infectious diseases such as Klebsiella pneumoniae urosepsis.

Abstract
Background and Objectives: Minimally invasive procedures, such as double-J ureteric stenting, could be a promising therapeutic alternative to conservative management of obstructive urinary tract pathology. We aimed to evaluate the safety and effectiveness of double-J ureteric stenting in pregnant women with ureterohydronephrosis or urolithiasis, along with their infectious complications, and to assess the pregnancy outcomes of this cohort of patients in comparison with a control group. Materials and Methods: This observational retrospective study included 52 pregnant patients who underwent double-J ureteric stenting for urologic disorders in the Urology Department of ‘C.I. Parhon’ University Hospital, and who were followed up at a tertiary maternity hospital- ‘Cuza-Voda’, Iasi, Romania. The control group (63 patients) was randomly selected from the patient’s cohort who gave birth in the same time frame at the maternity hospital, without urinary pathology. Clinical, sonographic, and laboratory variables were examined. Descriptive statistics, non-parametric tests, and a one-to-one propensity score-matched analysis were used to analyze our data. Results: The univariate analysis indicated a significant statistical difference between the control group and the interventional group regarding maternal age (p = 0.018), previous maternal history of renal colic (p = 0.005) or nephrolithiasis (p = 0.002). After applying the propensity score-matched analysis, cesarean delivery rates (p < 0.001), preterm labour (p = 0.039), premature rupture of membranes (p = 0.026), preterm birth rates (p = 0.002), and post-partum UTI rates (p = 0.012) were significantly different between the control group and the matched treatment group. Ureterohydronephrosis, whether simple (n = 37; 71.2%) or infected (n = 13; 25%), was the main indication for double-J ureteric stenting. Complications such as pain (n = 21; 40.3%), stent migration (n = 3; 5.76%) or encrustation (n = 2; 3.84%), as well as reflux pyelonephritis (n = 2; 3.84%) and gross hematuria (n = 1; 1.92%) were recorded during follow-up. Conclusions: Our results show that double-J stenting is a safe and effective treatment option for pregnant patients with obstructive urological disorders.

Abstract
Renal tuberculosis presenting as renal cyst is rare. Diagnosing renal tuberculosis in pregnancy is usually delayed due to its atypical presentation. We present a 28-year-old postpartum lady who delivered a healthy baby one month back, with history of intermittent fever and chills. She had high spiking fever (102° F), tachycardia (130/min) and computed tomography showed a 16 × 10 cm right renal cyst. Percutaneous drainage was done, 2 litres of thick pus drained and culture was sterile. After three weeks, deroofing and marsupialization of cyst was done. Biopsy revealed granulomatous inflammation composed of epitheliod histiocytes with central incipient necrosis suggestive of tuberculosis. She was treated with anti-tubercular drugs. As the infant was healthy and had no evidence of tuberculosis, no treatment was initiated. The mother is on follow up for 2 years. This case highlights the rare presentation of renal tuberculosis in puerperium.

Abstract
Candiduria is a common nosocomial infection in hospitalized patients, which may progress into life-threatening candidemia. Successful treatment of urosepsis requires early and effective antifungal therapy, while the available agents within three pharmacological classes each have characteristic pharmacokinetics and side effect profiles. Moreover, treatment of Candida spp. infections is becoming challenging due to increasing multi drug-resistance. Here, we present a case of candidemia resulting from a multi drug-resistant C. glabrata infection of the urinary tract. Due to resistance to fluconazole and a contraindication for amphotericin B, micafungin was used in the treatment, regardless of its unfavorable pharmacokinetic properties. Our study showed that despite the expected low levels in the urinary tract, micafungin was successful in the eradication of C. glabrata allowing full recovery of the patient. Thus, micafungin should be considered in the management of urosepsis caused by sensitive Candida spp.

Abstract
Purpose: To compare preoperative midstream urine cultures (PMUC) and renal pelvic urine culture (RPUC) or stone culture (SC) in predicting systemic inflammatory response syndrome (SIRS) and urosepsis after percutaneous nephrolithotomy (PCNL). Methods: We searched the PubMed, Web of Science, and EMBASE databases up to September 1, 2020, for relevant published studies. Two authors independently confirmed whether the literatures met the inclusion criteria and collected the data from the selected literatures. A meta-analysis was performed with Review Manager Software 5.4.1. A total of 14 studies with 3540 patients were selected and analyzed in the meta-analysis. Results: Pooled data showed that SC was associated with a higher sensitivity (odds ratios [OR] 2.36, confidence interval [95% CI] 1.31-4.25; p < 0.00001), positive predictive value (PPV) (OR 1.54, 95% CI 1.18-2.01; p = 0.16) and negative predictive values (OR 1.17, 95% CI 1.01-1.37; p = 0.06) in the diagnosis of SIRS and urosepsis after PCNL, and RPUC provided a significantly higher specificity (OR 2.70, 95% CI 2.16-3.38; p = 0.07) and PPV (OR 2.17, 95% CI 1.49-3.15; p = 0.48) than PMUC in the diagnosis of SIRS and urosepsis after PCNL. Conclusion: Intraoperative SC and RPUC are more reliable than PMUC in predicting postoperative SIRS and urosepsis, identifying causative organisms, and directing antibiotic therapy for patients who underwent PCNL. PMUC, SC, and RPUC should be routinely collected for the diagnosis and management of SIRS and urosepsis after PCNL.

Abstract
Introduction: With the rise in the use of ureteroscopy and laser stone lithotripsy (URSL), a proportionate increase in the risk of post-procedural urosepsis has also been observed. The aims of our paper were to analyse the predictors for severe urosepsis using a machine learning model (ML) in patients that needed intensive care unit (ICU) admission and to make comparisons with a matched cohort. Methods: A retrospective study was conducted across nine high-volume endourology European centres for all patients who underwent URSL and subsequently needed ICU admission for urosepsis (Group A). This was matched by patients with URSL without urosepsis (Group B). Statistical analysis was performed with ‘R statistical software’ using the ‘randomforests’ package. The data were segregated at random into a 70% training set and a 30% test set using the ‘sample’ command. A random forests ML model was then built with n = 300 trees, with the test set used for internal validation. Diagnostic accuracy statistics were generated using the ‘caret’ package. Results: A total of 114 patients were included (57 in each group) with a mean age of 60 ± 16 years and a male:female ratio of 1:1.19. The ML model correctly predicted risk of sepsis in 14/17 (82%) cases (Group A) and predicted those without urosepsis for 12/15 (80%) controls (Group B), whilst overall it also discriminated between the two groups predicting both those with and without sepsis. Our model accuracy was 81.3% (95%, CI: 63.7–92.8%), sensitivity = 0.80, specificity = 0.82 and area under the curve = 0.89. Predictive values most commonly accounting for nodal points in the trees were a large proximal stone location, long stent time, large stone size and long operative time. Conclusion: Urosepsis after endourological procedures remains one of the main reasons for ICU admission. Risk factors for urosepsis are reasonably accurately predicted by our innovative ML model. Focusing on these risk factors can allow one to create predictive strategies to minimise post-operative morbidity.

Abstract
Urosepsis is a very serious condition with a high mortality rate. The immune response is in the center of pathophysiology. The therapeutic management of these patients includes surgical treatment of the source of infection, antibiotic therapy and life support. The management of this pathology is multidisciplinary and requires good collaboration between the urology, intensive care, imaging and laboratory medicine departments. An imbalance of pro and anti-inflammatory cytokines produced during sepsis plays an important role in pathogenesis. The study of cytokines in sepsis has important implications for understanding pathophysiology and for development of other therapeutic solutions. If not treated adequately, urosepsis may lead to serious septic complications and organ sequelae, even to a lethal outcome.

Abstract
Emphysematous cystitis (EC) is a rare complicated urinary tract infection characterized by gas formation within the wall of the urinary bladder. Although EC has multifactorial etiology, commonly seen in elderly, diabetic and female sex; most of the cases of EC present along with emphysematous pyelonephritis (EPN) and full-blown urosepsis. We present a case of EC with EPN presented with features of sepsis managed conservatively. Furthermore, we reviewed the literature of published cases reports of EC with or without EPN from 1999 to 2019 (20 Years). From eligible 113 case reports, data of clinical presentation, demographic profile, risk factors, diagnostic methods, treatment, and prognosis were analyzed.

Abstract
Objectives: To investigate the factors associated with systemic infection after percutaneous nephrolithotomy (PCNL) and establish a predictive model to provide theoretical basis for the prevention of systemic inflammatory response syndrome (SIRS) and urosepsis correlate to percutaneous nephrostomy. Methods: Patients received PCNL between January 2016 and December 2020 were retrospectively enrolled. All patients were categorized into groups according to postoperative SIRS and urosepsis status. Single factor analysis and multivariate logistic regression analysis were performed to determine the predictive factors of SIRS and urosepsis after PCNL. The nomograms were generated using the predictors respectively and the discriminative ability of was assessed by analyses of receiver operating characteristic curves (ROC curves). Results: A total of 758 PCNL patients were enrolled in this study, including 97 (12.8%) patients with SIRS and 42 (5.5%) patients with urosepsis. Multivariate logistic regression analysis suggested that there were 5 factors related to SIRS, followed by preoperative neutrophil to lymphocyte ratio (NLR) (odds ratio, OR = 1.721, 95% confidence interval, CI [1.116–2.653], p = 0.014), S.T.O.N.E. score (OR = 1.902, 95% CI [1.473–2.457], p < 0.001), female gender (OR = 2.545, 95% CI [1.563–4.144], p < 0.001), diabetes history (OR = 1.987, 95% CI [1.051–3.755], p = 0.035), positive urine culture (OR = 3.184, 95% CI [1.697–5.974], p < 0.001). And there were four factors related to urosepsis, followed by preoperative NLR (OR = 1.604, 95% CI [1.135–2.266], p = 0.007), S.T.O.N.E. score (OR = 1.455, 95% CI [1.064–1.988], p = 0.019), female gender (OR = 2.08, 95% CI [1.063–4.07], p = 0.032), positive urine culture (OR = 2.827, 95% CI [1.266–6.313], p = 0.011). A nomogram prediction model was established to calculate the cumulative probability of SIRS and urosepsis after PCNL and displayed favorable fitting by Hosmer–Lemeshow test (p = 0.953, p = 0.872). The area under the ROC curve was 0.784 (SIRS) and 0.772 (urosepsis) respectively. Conclusion: Higher preoperative NLR, higher S.T.O.N.E. score, female gender, and positive urine culture are the most significant predictors of SIRS and urosepsis. Diabetes history is the predictor of SIRS. These data will help identify high-risk individuals and facilitate early detection of SIRS and urosepsis post-PCNL.

Abstract
BACKGROUND The patient suffering from urinary sepsis is often accompanied by elevated serum procalcitonin (PCT) levels and a decline in the average platelet count (PLT), which could result in a poor prognosis. This study aimed to evaluate the value of PCT and PLT in determining the severity of urinary sepsis. METHODS A total of 120 urosepsis patients enrolled were divided into a survival group and a death group, respectively, according to their status within 14 days after admission. Changes in PCT and PLT levels between the 2 groups were compared at different time points. A receiver operating characteristic (ROC) curve was eventually obtained to predict the prognostic value of PCT and PLT. RESULTS The PCT levels in the survival group declined gradually after admission, and the PLT decreased at first but increased rapidly in subsequence. The PCT level in the death group, however, declined in a flat-slope trend or was hardly noticeable together with the number of PLT reduced significantly. In particular, it is on the 3rd day that PCT tended to positively correlate with acute physiological and chronic health score II (APACHE II) score (r = 0.730, P < .05), but negatively with PLT (r = 0.472, P < .05). The APACHE II score and PLT (r = 0.612, P < .05) were also negatively correlated with each other. As indicated by the ROC curve, the PCT level on the 3rd day after admission was of great value for the clinical mortality prognosis, and the area under the curve was 0.858. Moreover, PLT also has a high predictive value for prognosis. Area under the curve is 0.951. When the PLT was more than 51 × 109 /L, the sensitivity was up to 90%, and the specificity was 90%. CONCLUSION PLT and PCT levels are closely related to the APACHE II score, which could indicate the severity of urosepsis in patients. The contribution of this study was to confirm that dynamic monitoring of the changes in PCT and PLT helps determine the prognosis of urosepsis patients.

Abstract
Background To compare severe infectious complication rates after transrectal prostate biopsies between cephalosporins and fluoroquinolones for antibiotic monoprophylaxis. Material and Methods In the multi-institutional cohort, between November 2014 and July 2020 patients received either cefotaxime (single dose intravenously), cefpodoxime (multiple doses orally) or fluoroquinolones (multiple-doses orally or single dose intravenously) for transrectal prostate biopsy prophylaxis. Data were prospectively acquired and retrospectively analyzed. Severe infectious complications were evaluated within 30 days after biopsy. Logistic regression models predicted biopsy-related infectious complications according to antibiotic prophylaxis, application type and patient- and procedure-related risk factors. Results Of 793 patients, 132 (16.6%) received a single dose of intravenous cefotaxime and were compared to 119 (15%) who received multiple doses of oral cefpodoxime and 542 (68.3%) who received fluoroquinolones as monoprophylaxis. The overall incidence of severe infectious complications was 1.0% (n=8). No significant differences were observed between the three compared groups (0.8% vs. 0.8% vs. 1.1%, p=0.9). The overall rate of urosepsis was 0.3% and did not significantly differ between the three compared groups as well. Conclusion Monoprophylaxis with third generation cephalosporins was efficient in preventing severe infectious complications after prostate biopsy. Single intravenous dose of cefotaxime and multiday regimen of oral cefpodoxime showed a low incidence of infectious complications <1%. No differences were observed in comparison to fluoroquinolones.

Abstract
Xanthogranulomatous pyelonephritis (XGP) is considered to be a rare variant of chronic pyelonephritis, which results in non-functioning kidneys in patients. The exact etiology of this disease is still unknown, and hence even its pathophysiology remains unclear. We present a case of a 27-year-old Saudi male patient who had been bed-bound with a known case of a congenital anomaly with severe kyphoscoliosis, bilateral lower limbs deformity with paraplegia, and a ventriculoperitoneal shunt since childhood. The patient was brought to the emergency department (ED) with right flank pain associated with fever and difficulty in breathing. The patient had a past medical history of recurrent urinary tract infection (UTI) with up to two incidences per year and renal stones. He had been recently discharged from the ICU of another hospital with sepsis due to UTI. An abdominal CT scan was performed, which showed a mass in the upper lobe of the right kidney measuring about 9 x 8 x 6 cm, suggestive of XGP. The final diagnosis was severe urosepsis secondary to right obstructive pyelonephritis. Patients with XGP usually present with nonspecific symptoms including back and abdominal pain, fever, UTI, and the condition is more common among middle-aged women. Ultimately, early detection and diagnosis, followed by prompt treatment with partial or total nephrectomy are associated witha good prognosis for patients with XGP.

Abstract
Introduction Insufficient attention has been directed towards urosepsis. Notably, no protocols or clinical decision rules currently exist outlining the appropriate use of imaging in uroseptic patients. The primary objective of our study was to retrospectively evaluate uroseptic emergency department (ED) patients who underwent abdominal imaging, to report the proportion of patients with imaging findings necessitating emergent surgical consultation. Methods We retrospectively identified 1142 patients ≥ 18 years of age that presented to the ED from January 2009 to December 2012 with ICD9 code indicative of urosepsis. All included patients underwent ED-ordered abdominal computerized tomography (CT) or retroperitoneal ultrasound (US). Imaging and urinalysis (UA) results were categorized. We report proportions with odds ratios and 95% confidence intervals. Results Of 1142 patients, we excluded 80 for neg UA, 167 for < 2 SIRS (systemic inflammatory response syndrome), 320 for positive blood cultures, and 37 for incomplete data. This yielded 538 patients which the authors reviewed the results of the CT or US to determine the proportion who required emergent surgical consultation and who underwent surgical or interventional procedure. There were 243 (45%) that had CT or US results that necessitated emergency surgical consultation, of those 180 (33%) underwent surgical or interventional procedure. Similar rates of emergency surgical consultation occurred when sub-divided by positive versus equivocal UA, with 43% and 47%, respectively. Conclusions Forty-five percent of our abdominally imaged urosepsis cohort had imaging findings that necessitated emergent surgical consultation, with a similar proportion in the subset with positive versus equivocal UA. The utility of abdominal imaging in this population should be studied prospectively.

Abstract
Introduction: Urosepsis is a serious potential complication of ureteroscopic procedures for stone disease, yet the risk factors for this complication are not well characterized. The purpose of this systematic review with meta-analysis was to identify potential risk factors for urosepsis after ureteroscopy (URS) for stone disease. Materials and Methods: We performed systematic searches of Medline, Embase, and the Cochrane Central Register of Controlled Trials for studies reporting at least one prospectively defined risk factor for urosepsis after URS. Studies that only reported rates of isolated fever, urinary tract infection (UTI), or pooled infectious complications were excluded. The risk factors evaluated in this review were age, sex, body mass index, diabetes mellitus, ischemic heart disease, recent UTI, pyuria, hydronephrosis, stone history, stone size, preoperative stent placement, preoperative positive urine culture, and procedure time. A random effects meta-analysis model with inverse variance weighting was used where the statistic of interest was the odds ratio for dichotomous variables and the mean difference for continuous outcomes. Results: In 13 studies (5 prospective) with 5597 patients, the pooled incidence of postoperative urosepsis was 5.0% (95% confidence interval: 2.4-8.2). Six risk factors were statistically associated with increased postoperative urosepsis risk-preoperative stent placement (odds ratio = 3.94, p < 0.001, 6 studies), positive preoperative urine culture (odds ratio = 3.56, p < 0.001, 6 studies), ischemic heart disease (odds ratio = 2.49, p = 0.002, 2 studies), older age (mean difference = 2.7 years, p = 0.002, 6 studies), longer procedure time (mean difference = 9 minutes, p = 0.02, 1 study), and diabetes mellitus (odds ratio = 2.04, p = 0.04, 6 studies). Conclusions: Current evidence suggests that among patients undergoing URS for treatment of stone disease, the risk of postoperative urosepsis was 5.0%. Older age, diabetes mellitus, ischemic heart disease, preoperative stent placement, a positive urine culture, and longer procedure time were associated with increased postoperative urosepsis risk. These results will assist urologists with preoperative risk stratification before ureteroscopic procedures.

Abstract
The incidence and geographic distribution of urosepsis, a life-threatening condition in older adults, is not well understood. The Florida State Inpatient Databases (2012-2014) showed an increase in the incidence of community-acquired urosepsis (5.37 to 6.16 per 1000), particularly among Hispanic older adults residing in low socioeconomic, urban areas with large numbers of nursing homes. These findings suggest a state policy is needed to address community-based preventative care and education for early detection of urosepsis in low-income urban areas. It is important for local health departments to partner with nursing homes to address disparities in care that disproportionally impact Hispanics.

Abstract
Introduction and Background: Urosepsis is commonly predicted by the systematic inflammatory response syndrome (SIRS) criteria. We report a case of urosepsis preceded only by thrombocytopenia. Case Presentation : An 80-year-old Caucasian female presented with recurrent urinary tract infections, type 1 second-degree heart block (Mobitz I), and chronic deep venous thrombosis for which she was taking apixaban. Computed tomography (CT) revealed a 1.3 cm right upper pole calculus (Hounsfield units (HU) = 704) and a left 5 mm nonobstructing interpolar calculus (HU = 904). A preoperative urine culture was sterile as the patient was on antibiotics. While on antibiotic coverage, the patient underwent bilateral retrograde intrarenal surgery with bilateral stent placement: the procedure time was 188 minutes. She was continued on vancomycin and gentamicin immediately postoperatively. On postoperative day (POD) 1, she was feeling well; her vital signs were within normal limits. However, the hemoglobin and the platelet counts declined from 12.4 to 10.0 g/dL and from 215 to 58/mm3, respectively. Because of the unexplained thrombocytopenia, the patient was kept at the hospital. In the afternoon, she became hypotensive (78/37 mm Hg) and a rapid response was called. She was admitted to the surgical intensive care unit and antibiotics were broadened. On POD 2, the patient met sepsis SIRS criteria with white blood cell (WBC) of 2.9/mm3 and heart rate of 92 bpm. Stone culture was positive for methicillin-resistant Staphylococcus aureus (MRSA). On POD 3, her blood pressure had returned to 116-142/47-84. On POD 5, platelet count recovered to 94/mm3 and WBC to 3.8/mm3. She was discharged on POD 6 with a 2-week ongoing course of intravenous vancomycin. On follow-up 7 weeks postoperatively, she was asymptomatic with WBC of 6.5/mm3 and platelet count of 206/mm3. Follow-up CT demonstrated normal renal anatomy with subcentimeter calculi clustered within the left renal parenchyma and no stones on the right side. Conclusion: This case shows an uncommon non-SIRS presentation of postoperative urosepsis signaled only by thrombocytopenia.

Abstract
Purpose Postoperative anemia is associated with increased morbidity and mortality in patients undergoing surgery. Anemia is also a common feature during sepsis. Therefore, here, we aimed to investigate the safety and efficacy of intravenous iron isomaltoside 1000 (Monofer®) in patients undergoing elective urologic surgery and in those with urosepsis. Materials and Methods This multicenter study was conducted through the review of the medical records of patients with postoperative anemia undergoing elective urologic surgery or with urosepsis in a multicenter hospital. Patients received a single intravenous iron isomaltoside (IIM), and their hemoglobin (Hb) level was evaluated before and after administration of IIM. Safety data included adverse effects and hypersensitivity reactions. In addition, the patients were divided into three groups (200 mg, 400 mg, and 600 mg IIM) to compare Hb changes before and after the administration of IIM. Results The study analyzed 52 men and 30 women with a mean age of 67 years. There was a significant difference between pre-treatment Hb and post-treatment Hb according to the type of the surgery after administration (p=0.01) of IIM in patients with postoperative anemia, and the mean preoperative Hb before IIM administration was 8.5 g/dL and that after IIM administration was 9.9 g/dL (p=0.006) in patients with urosepsis. The mean preoperative Hb changed from 10 g/dL to 11 g/dL after administration (p<0.001) of IIM in the whole cohort. There were no side effects due to the administration of intravenous IIM. Conclusion A single perioperative intravenous injection of IIM 1000 significantly increased the Hb level in patients with anemia who underwent urologic elective surgery. Moreover, this treatment can be considered to have potential clinical benefits for anemia caused by sepsis.

Abstract
BACKGROUND To investigate the usefulness of serum procalcitonin (PCT) in the early diagnosis of urinary tract infection (UTI) and urosepsis following transrectal prostate biopsy. METHODS In this prospective observational study, 227 patients who underwent transrectal ultrasound-guided prostate biopsy were evaluated. The relationship between urosepsis and age, serum PCT, C-reactive protein, prostate-specific antigen (PSA), prostate volume, PSA density and pathologic results following biopsy was assessed. Serum PCT level was measured in all patients immediately before the biopsy and at the post-biopsy day 2. RESULTS Of the 227 patients, 11 (4.8%) developed UTI with positive urine culture without urosepsis and 5 (2.2%) developed urosepsis within 30 days after biopsy. The concentration of PCT was within the normal range before the biopsy. Procalcitonin concentration at post-biopsy day 2 was significantly higher in patients who developed urosepsis (1.91 ± 2.99 ng/ml vs. 0.05 ± 0.08 ng/ml; p = .004) compared with non-UTI patients. Only elevated PCT level at post-biopsy day 2 was a statistically significant independent predictor of post-biopsy urosepsis. The area under the ROC curve for the prediction of urosepsis was 0.976 (95%CI: 0.941-1.000) and a cut-off 0.095 ng/ml in the level of PCT at post-biopsy day 2 yielded a sensitivity of 100% and specificity of 93.8% in detecting urosepsis following biopsy. CONCLUSIONS Procalcitonin appears to be a useful early biomarker to predict the urosepsis following prostate biopsy. Patients with elevated PCT value should be closely monitored after the biopsy.

Abstract
Carnitine palmitoyltransferase II (CPT II) deficiency represents an inherited defect in mitochondrial long-chain fatty acid oxidation. Rhabdomyolysis with necrosis of muscle is caused by the destruction of skeletal muscle and leads to systemic, multiorgan complications due to the release of intracellular muscle components. Severe rhabdomyolysis may be triggered by combination of a genetic predisposition, including CPT II deficiency, with additionally acting causes. Generally, patients with CPT II deficiency are rarely clinical recognized and reported. We describe a patient presenting severe rhabdomyolysis due to urosepsis, who, in genetic testing, demonstrated the homozygous CPT II deficiency (c.338C>T, p.Ser113Leu) mutation. The diagnosis of CPT II deficiency helped this patient to put the symptoms into context, and this reduced myopathy and the risk of recurring rhabdomyolysis. We report on this patient to increase awareness of diagnostic and medical management in CPT II deficiency.

Abstract
Introduction and Objective: Patients presenting with a urinary tract infection with kidney or ureteral stones is a urologic emergency often achieve early clinical stability but remain hospitalized while awaiting results from urine antibiotic sensitivity analyses. We aimed to identify clinical predictors of antibiotic resistance in patients who underwent urgent urinary tract decompression for sepsis and obstructive urolithiasis to facilitate early discharge on empiric oral antibiotics. Methods: Patients who underwent emergent urinary tract decompression for sepsis and an obstructing ureteral stone from 2014 to 2018 at two academic medical institutions were identified. Emergent stent placement was performed and patients were treated with broad-spectrum intravenous antibiotics. We assessed the association between clinical parameters at the time of presentation and resistance to at least one antibiotic from urine culture using the Wilcoxon test and Fisher exact test for continuous and categorical variables, respectively. Multivariate logistic regression was then performed using all significant variables from univariate analysis. Results: Out of 134 patients, 84 patients (62.7%) had urine cultures resistant to at least one antibiotic. On univariate analysis, patients with resistant cultures were significantly more likely to have had previous ureteroscopy, require postoperative intensive care unit-level care, have bacteremia, and a longer length of stay. In multivariate analysis using significant variables from univariate analysis, only previous ureteroscopy was significantly associated with antibiotic resistance with an increased odds of 6.95 (p = 0.011). Conclusions: In this study, we show that a history of ureteroscopy is significantly associated with antibiotic resistance in both univariate and multivariate analyses. Our findings suggest that patients with history of ureteroscopy should await urine culture results, while those without a history of ureteroscopy may be discharged early on empiric oral antibiotics. However, future studies are necessary to determine the effectiveness of this predictor.

Abstract
Takotsubo cardiomyopathy (TCM) is a rare but reversible myocardial left ventricular (LV) dysfunction, which mimics acute coronary syndrome (ACS) without the presence of significant coronary artery disease (CAD). Emotional stressors may include the death of kin or a life-threatening medical diagnosis whereas physical stressors include infections, endoscopic procedures, exacerbation of asthma, or systemic disorders. A 90-year-old female presented to the ED with nausea, intermittent chest heaviness, and generalized weakness for a duration of three days. Her troponin-I was elevated and an electrocardiogram (EKG) showed T-wave inversions in leads V2-V6 and no ST-segment changes. An echocardiogram (ECHO) revealed an ejection fraction (EF) of 35%-40% with anteroapical hypokinesis. She underwent cardiac catheterization showing nonobstructive CAD. She was diagnosed with pan-sensitive Escherichia coli urosepsis and started on ceftriaxone. She improved clinically and was discharged. A repeat ECHO done a month later showed normal EF. Urosepsis-induced TCM has rarely been reported in the literature. Physicians should have a high index of suspicion of TCM in patients with symptoms mimicking ACS in the presence of a physical stressor like an infection. We report the case of TCM, which resulted from a urinary tract infection (UTI) in an elderly female.

Abstract
Urosepsis contributes significantly to the epidemiology of sepsis. Urosepsis can be classified as community acquired or hospital acquired, depending upon the origin of infection acquisition: either from the community or from a healthcare facility. A great deal of literature is available about nosocomial urosepsis, but the literature regarding community-acquired urosepsis (CAUs) is limited, and studies are underpowered. The aim of our study was to determine the epidemiology, bacteriology, severity, and outcome of CAUs. Methods and Patients: All patients admitted from the emergency department to the surgical intensive care unit (SICU) with urosepsis over a period of 10 years were identified and included retrospectively from the SICU registry. The study was retrospective. Data were entered into the SPSS program version 23, and groups were compared by using chi-square and t-tests. Results were considered statistically significant at p ≤ 0.05. Results: During the study period, 302 patients with CAUs were admitted to the SICU. The common etiology was obstructive uropathy (60%). The Local Arab population outnumbered the non-Arab population (164/54.3%), and there were equal numbers of patients of both genders. Diabetes mellitus and hypertension together were the common comorbidities. Seventy-five percent of patients had acute kidney injury (AKI). Thirty-eight percent of patients had percutaneous nephrostomy, and 24.8% of patients underwent endoscopic stent insertion to relieve the obstruction. Ninety-three percent of patients were admitted with septic shock, and 71.5% had bacteremia. The common bacteria (36.1%) was extended-spectrum beta-lactamase-(ESBL)-producing bacteria, with a predominance of Escherichia coli (31.5%). Fifty-four percent of patients required a change of antibiotics to carbapenem. Eighty-two percent of patients had acute respiratory distress syndrome (ARDS). Patients with bacteremia had a statistically significant AKI, ARDS, and septic shock (p < 0.001). Male patients had a significantly higher incidence of oliguria, intubation, and ARDS (p < 0.05). Eight patients died of urosepsis during the study period, giving a mortality rate of 2.6%. Conclusion: In our patients, obstruction of urine flow was the most common cause of CAUs. Our urosepsis patients had a higher bacteremia rate, which led to higher incidences of organ dysfunction and septic shock. ESBL bacteria were a frequent cause of urosepsis, requiring a change of the initial antibiotic to carbapenem. Male patients had a significantly higher rate of organ dysfunction. Mortality in our urosepsis patients was lower than mentioned in the literature.

Abstract
Hafnia alvei, belonging to the Enterobacteriaceae family, is a gram-negative, facultative anaerobe. The organism predominantly colonizes the gastrointestinal tract and, less often, the tissues, urine, and catheters. A 75-year-old male presented with a dry cough, fatigue, decreased appetite, intermittent disorientation, and difficulty ambulating. He had a history of self-catheterization due to urinary retention. He was scheduled to undergo transcatheter aortic valve replacement for enterococcal endocarditis. Physical examination was not significant for any changes. Urine analysis revealed positive leukocyte esterase, the presence of red and white blood cells, urine bacteria, and hyaline casts. The patient was started on empiric intravenous ceftriaxone. Urine culture grew Hafnia alvei and he was switched over to cefepime due to greater susceptibility. On day four, he started deteriorating clinically and was treated with four pressors but remained hypotensive and eventually became anuric. The patient developed septic shock with multiple organ dysfunction syndromes. Despite all measures, his clinical condition failed to improve, and he was continued with comfort measures only. The literature on Hafnia alvei-induced urosepsis is poor and fragmentary. Our patient showed resistance to most beta-lactam antibiotics, including cefuroxime, ceftriaxone, and ceftazidime, along with intermediate susceptibility to piperacillin/tazobactam and was managed with intravenous cefepime based on the sensitivity report. Inducible Bush group 1 beta-lactamase produced by Hafnia alvei is postulated to be responsible for antibiotic resistance. Physicians should remain vigilant of Hafnia alvei-induced urosepsis in patients with long-term catheterization initiating appropriate treatment.
