Construction and validation of the nomogram predictive model for post-percutaneous nephrolithotomy urinary sepsis.

OBJECTIVE: This study aimed to construct and validate a simple and accurate clinical nomogram for predicting the occurrence of post-percutaneous nephrolithotomy sepsis, aiming to assist urologists in the early identification, warning, and early intervention of urosepsis, and to provide certain evidence-based medicine basis. METHODS: This study included patients who underwent PCNL surgery due to kidney or upper ureteral stones at the Department of Urology, Affiliated Hospital of Zunyi Medical University, from January 2019 to September 2022. This study utilized univariate and multivariate logistic regression analysis to screen and evaluate the risk factors for sepsis and construct a predictive model. An evaluation was performed using the receiver operating characteristic curve, calibration curve, and decision curve analysis curve. All statistical analyses were conducted using R version 4.2. RESULTS: A total of 946 patients who underwent post-PCNL were included in this study, among whom 69 patients (7.29%) developed post-PCNL urinary sepsis. Multiple-factor logistic regression analysis identified four independent risk factors associated with post-PCNL urinary sepsis, including positive urinary nitrite (OR = 5.9, P < 0.001), positive urine culture (OR = 7.54, P < 0.001), operative time ≥ 120 min (OR = 20.93, P = 0.0052), and stone size ≥ 30 mm (OR = 13.81, P = 0.0015). The nomogram model demonstrated good accuracy with an AUC value of 0.909, and in the validation cohort, the AUC value was 0.922. The calibration curve indicated a better consistency between the predictive line chart and the actual occurrence of post-PCNL urinary sepsis. The decision curve analysis curve showed favorable clinical utility. CONCLUSION: Preoperative positive urine culture, positive urinary nitrite, operative time ≥ 120 min, and stone size ≥ 30 mm are independent risk factors for developing post-PCNL urinary sepsis. The constructed line chart based on these factors effectively assesses the risk of urinary sepsis in patients after PCNL.

Objective To investigate the safety and effectiveness of percutaneous nephrostomy in the treatment of obstructive urinogenic sepsis complicated with thrombocytopenia.Methods Clinical data of 116 patients with urogenic sepsis complicated with thrombocytopenia admitted to Xiaogan Hospital of Wuhan University of Science and Technology from October 2017 to May 2021 were collected.There were 23 patients with abnormal renal function indexes(serum creatinine＞500 mmol/L).Preoperative urinary tract CT or ultrasound were performed to confirm hydronephrosis.According to the number of platelets in preoperative blood routine,they were divided into study group(platelet＜50 × 109/L)and control group(platelet ≥ 50 × 109/L).Percutaneous nephrostomy was performed under ultrasound guidance in both groups.The outcome indexes included the success rate of operation,body temperature,routine white blood cell count,the time to return to normal of procalcitonin,postoperative bleeding,shock,and side injury.Results In the study group,preoperative fever time was(6.9±2.2)days,platelet count was(35± 10.2)x 109/L,preoperative procalcitonin(PCT)was(36±6.2)ng/ml,and serum creatinine increased by 30％.While,the data in control group were(4.2+2.0)days,(115±58.9)x 109/L,(20±2.6)ng/ml and 12％,respectively.The difference between the two groups was statistically significant(P＜0.05).The recovery time of PCT in study group and control group was(6.9±2.8)days and(4.8±1.5)days,respectively.The normal recovery time of body temperature was(36.2±3.5)hours and(28.5±2.3)hours,respectively.The recovery time of white blood cell count was(5.3± 1.2)days and(3.2±2.5)days,respectively.The recovery time of platelet was(6.0±2.3)days and(3.5±2.0)days,respectively.The difference between the two groups was statistically significant(P＜0.05).There was no significant difference in surgical success rate,postoperative collateral injury,massive hemorrhage,shock and other complications between the two groups(P＞0.05).Conclusion Percutaneous nephrostomy(PCN)is effective and safe in the treatment of urogenic sepsis with thrombocytopenia,and it is worth popularizing.

Risk factors of concurrent urinary sepsis in patients with diabetes mellitus comorbid with upper urinary tract calculi.

BACKGROUND: Urinary sepsis is frequently seen in patients with diabetes mellitus (DM) complicated with upper urinary tract calculi (UUTCs). Currently, the known risk factors of urinary sepsis are not uniform. AIM: To analyze the risk factors of concurrent urinary sepsis in patients with DM complicated with UUTCs by logistic regression. METHODS: We retrospectively analyzed 384 patients with DM complicated with UUTCs treated in People's Hospital of Jincheng between February 2018 and May 2022. The patients were screened according to the inclusion and exclusion criteria, and 204 patients were enrolled. The patients were assigned to an occurrence group (n = 78) and a nonoccurrence group (n = 126). Logistic regression was adopted to analyze the risk factors for urinary sepsis, and a risk prediction model was established. RESULTS: Gender, age, history of lumbago and abdominal pain, operation time, urine leukocytes (U-LEU) and urine glucose (U-GLU) were independent risk factors for patients with concurrent urinary sepsis (P < 0.05). Risk score = 0.794 × gender + 0.941 × age + 0.901 × history of lumbago and abdominal pain - 1.071 × operation time + 1.972 × U-LEU + 1.541 × U-GLU. The occurrence group had notably higher risk scores than the nonoccurrence group (P < 0.0001). The area under the curve of risk score for forecasting concurrent urinary sepsis in patients was 0.801, with specificity of 73.07%, sensitivity of 79.36% and Youden index of 52.44%. CONCLUSION: Sex, age, history of lumbar and abdominal pain, operation time, ULEU and UGLU are independent risk factors for urogenic sepsis in diabetic patients with UUTC.

【Objective】 To determine the risk factors of urinary sepsis secondary to minimally invasive percutaneous nephrolithotomy (mPCNL) in patients with negative preoperative urine culture (UC). 【Methods】 A total of 274 patients with negative preoperative UC treated with mPCNL during Jan.2016 and Jun. 2021 were retrospectively analyzed. The incidence of urinary sepsis was observed, and the general data of patients with or without urinary sepsis after mPCNL were compared. logistic regression model was used to analyze the risk factors of urinary sepsis after mPCNL. 【Results】 Urinary sepsis occurred in 11 cases (4.01%). Univariate analysis showed that urinary sepsis was associated with gender, body mass index, stone load, diabetes, urine WBC ≥2+, urinary nitrite, procalcitonin, and operation time. Multivariate logistic regression analysis showed that the independent risk factors of urinary sepsis after mPCNL included diabetes (OR=2.34, 95%CI=1.051-5.43, P=0.037), stone load (OR=7.51, 95%CI=3.17-7.38, P=0.045), urine WBC≥2+ (OR=4.57, 95%CI=6.75-11.38, P=0.032), urinary nitrite positive (OR=6.45, 95%CI=0.93-26.87, P=0.028) and operation time≥120 min (OR=3.53, 95%CI=1.41-8.85, P=0.042). 【Conclusion】 Diabetes, stone load, urinary WBC ≥2+, positive urinary nitrite and operation time ≥120 minutes are the risk factors of urinary sepsis after mPCNL in patients with negative urine culture.

Research progress on early diagnositic biomarkers of urinary sepsis / 中华泌尿外科杂志

The accuracy of the Sepsis-3 definition in the diagnosis of sepsis has been widely accepted and applied. Indicators such as Procalcitonin(PCT), white blood cell(WBC), C-reactive protein(CRP), platelets(PLT) and albumin are the most extensively and conveniently applied in early alert and diagnosis of urinary sepsis. PCT has a higher specificity and sensitivity compared to other biomarkers, and a sharp drop in WBC is a strong warning for septic shock. However, CRP has a relatively low specificity. IL-6, CD64, Presepsin, miRNA, and PTX-3, among others, are more valuable emerging indicators with higher sensitivity and specificity. However, uniform and standardized technology is necessary for a high quality testing. The combination of multiple biomarkers with a clinical scoring system is more useful than individual biomarkers clinically. This article mainly reviewed the progress of research on indicators related to early alert and diagnosis of urinary sepsis during recent years.

Infected hepatic cyst complicating urinary sepsis.

Congenital hepatic cysts are a common disorder. Usually they are asymptomatic and do not have to be treated. However, some serious complications can occur. We report here the case of an 86-year old patient who has been treated by a percutaneous drainage for an infected solitary hepatic cyst due to urinary sepsis. She was admitted to the Department of Internal Medicine for epigastric pain with fever and chills. The patient was treated for a urinary tract infection 3 weeks ago by her General Practitioner. On admission, blood tests showed 21 620 neutrophils per microliter with a C-reactive protein level at 443.7 mg/L, procalcitonin > 200 ng/mL, total bilirubin at 1.43 mg/dL, lactate dehydrogenase at 666 U/L and alanine aminotransferase at 227 U/L. Urinalysis and hemocultures highlighted the presence of Escherichia coli and Streptococcus constellatus. The abdominal tomodensitometry indicated the presence of a left hepatic biliary cyst with banal appearance. She was first treated with intravenous amoxicillin clavulanic acid. After a few days, another abdominal tomodensitometry with contrast pinpointed a large abscess of 11 centimeters in diameter extending to liver segments II and IV with a similar small lesion in segments IV and V. clindamycin per os was added to the treatment because of its good diffusion in tissues. Percutaneous drain was inserted under tomodensitometric control and stayed in place until the follow-up at three weeks. Bacteriologic culture on the fluid sample demonstrated the presence of Escherichia coli and Streptococcus constellatus. The abscess completely regressed after 6 weeks of treatment and the biologic abnormalities resolved at the same time.

Predictive factors for Enterococcus faecalis in complicated community-acquired urinary tract infections in older patients.

AIM: Risk factors for complicated community acquired Enterococcus faecalis urinary tract infection (UTI) in older patients are not well known. METHODS: We identified the predictive factors for E. faecalis on a cohort of 659 older patients admitted to hospital with complicated UTI. We also examined the adequacy of empirical antimicrobial therapy and outcomes in E. faecalis UTI. Multivariable logistic regression was used to identify predictors of E. faecalis UTI. RESULTS: A total of 87 (13.2%) patients had E. faecalis UTI; of these 63.2% were men, their mean age was 82.3 years and they had a great number of comorbidities. Severe sepsis or septic shock was present in 50.5%, and bacteremia was present in 26%. Indwelling urinary catheter and previous urinary instrumentation were risk factors for E. faecalis UTI by multivariate analysis (OR 2.05; 95% CI 1.15-3.65 and OR 2.16; 95% CI 1.08-4.34, respectively). Inadequate empirical antimicrobial therapy was higher in E. faecalis UTI than in UTI caused by Gram-negative microorganisms (66.6% vs 19%, P < 0.001). No significant differences in length of hospital stay or mortality were noted between E. faecalis and Gram-negative UTI. CONCLUSIONS: In older patients admitted to hospital with complicated community-acquired UTI, E. faecalis should be considered for empirical treatment if the patient has a urinary catheter or previous urinary tract instrumentation in order to avoid inadequate empirical antibiotic therapy.

[Association of inflammatory indices with the severity of urinary sepsis: analysis of 70 cases].

OBJECTIVE: To analyze the association of the clinical inflammatory indices with the severity of urinary sepsis. METHODS: We reviewed the clinical data of 70 patients with urinary sepsis treated in our hospital between January, 2013 and April, 2018. All the patients were diagnosed in line with the Guidelines for Diagnosis and Treatment of Urological Diseases in China (2014 edition), including 22 patients with sepsis, 12 with hypotension and severe sepsis, 17 with septic shock, and 19 with critical septic shock. White blood cell count (WBC), neutrophil percentage (N%), platelets (PLT), fibrinogen (FIB), Ddimer, interleukin-6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) were examined in all the cases and compared among the 4 groups. The correlations of these inflammatory markers with the severity of sepsis were analyzed using logistic regression analysis. RESULTS: The 4 groups of patients showed significant differences in N%, PLT, D-dimer, and PCT (P < 0.05) but not in CRP (P>0.05). Kruskal-Wallis Pairwise comparisons showed that the N% and PCT in patients with sepsis differed significantly from those in the other 3 groups; platelets in patients with sepsis differed significantly from those in patients with septic shock and critical septic shock; D-dimer differed significantly between patients with sepsis and those with septic shock. Among the 4 groups, the median levels of PLT decreased and PCT and N% increased with the worsening of sepsis. Logistic regression analysis indicated that PCT (r=0.186, P=0.000), N% (r=0.047, P=0.035) and PLT (r=-0.012, P=0.003) were significantly correlated with the severity of sepsis in these patients. CONCLUSIONS: PCT, PLT and N% are all significantly correlated with the severity of sepsis, and their combined detection can be informative for assessing the severity of sepsis to facilitate clinical decisions on treatment.

Smartphone-based pathogen diagnosis in urinary sepsis patients.

BACKGROUND: There is an urgent need for rapid, sensitive, and affordable diagnostics for microbial infections at the point-of-care. Although a number of innovative systems have been reported that transform mobile phones into potential diagnostic tools, the translational challenge to clinical diagnostics remains a significant hurdle to overcome. METHODS: A smartphone-based real-time loop-mediated isothermal amplification (smaRT-LAMP) system was developed for pathogen ID in urinary sepsis patients. The free, custom-built mobile phone app allows the phone to serve as a stand-alone device for quantitative diagnostics, allowing the determination of genome copy-number of bacterial pathogens in real time. FINDINGS: A head-to-head comparative bacterial analysis of urine from sepsis patients revealed that the performance of smaRT-LAMP matched that of clinical diagnostics at the admitting hospital in a fraction of the time (~1 h vs. 18-28 h). Among patients with bacteremic complications of their urinary sepsis, pathogen ID from the urine matched that from the blood - potentially allowing pathogen diagnosis shortly after hospital admission. Additionally, smaRT-LAMP did not exhibit false positives in sepsis patients with clinically negative urine cultures. INTERPRETATION: The smaRT-LAMP system is effective against diverse Gram-negative and -positive pathogens and biological specimens, costs less than $100 US to fabricate (in addition to the smartphone), and is configurable for the simultaneous detection of multiple pathogens. SmaRT-LAMP thus offers the potential to deliver rapid diagnosis and treatment of urinary tract infections and urinary sepsis with a simple test that can be performed at low cost at the point-of-care.

Objective To investigate the effect of early continuous renal replacement therapy on the prognosis of urinary sepsis after surgery for upper urinary tract calculi.Methods The clinical data of 59 patients with urinary sepsis after surgery for upper urinary tract calculi were retrospectively analyzed.In 59 patients with urinary sepsis,9 patients with early persistent renal replacement therapy were selected as the experimental group and 50 patients without early continuous renal replacement therapy as the control group. The age,sex ratio,diabetes,hypertension,the average operation time were no significant difference(P>0.05).Preoperative urinary tract infection,the experimental group preoperative urinary tract infection was significantly higher than the control group(77.8% vs.32.0%,P<0.05).In the results of preoperative urine culture positive ratio,the experimental group was also significantly higher than the control group,the difference was statistically significant(P<0.05).The changes of prognostic factors in patients with or without continuous renal replacement therapy were analyzed.Results In terms of the changes of postoperative laboratory results,the decrease of procalcitonin(PCT),C-reactive protein,white blood cell count and neutrophil ratio in the experimental group was significantly larger than that in the control group, and the difference was statistically significant;on the increase of hemoglobin,platelet count,fibrinogen,the standard bicarbonate level from blood gas analysis in the experimental group increased significantly more than the control group,the difference between the two groups were statistically significant.Conclusions Early renal replacement therapy in patients with urinary sepsis after upper urinary tract calculi surgeries can improve the prognosis of patients.

Cross-sectional imaging of complicated urinary infections affecting the lower tract and male genital organs.

Complicated urinary tract infections (C-UTIs) are those associated with structural or functional genitourinary abnormalities or with conditions that impair the host defence mechanisms, leading to an increased risk of acquiring infection or failing therapy. C-UTIs occur in patients with risk factors such as neurogenic dysfunction, bladder outlet obstruction, obstructive uropathy, bladder catheterisation, urologic instrumentation or indwelling stent, urinary tract post-surgical modifications, chemotherapy- or radiation-induced damage, renal impairment, diabetes and immunodeficiency.Multidetector CT and MRI allow comprehensive investigation of C-UTIs and systemic infection from an unknown source. Based upon personal experience at a tertiary care hospital focused on the treatment of infectious illnesses, this pictorial essay reviews with examples the clinical features and cross-sectional imaging findings of C-UTIs affecting the lower urinary tract and male genital organs. The disorders presented include acute infectious cystitis, bladder mural abscesses, infections of the prostate and seminal vesicles, acute urethritis and related perineal abscesses, funiculitis, epididymo-orchitis and scrotal abscesses. Emphasis is placed on the possible differential diagnoses of lower C-UTIs.The aim is to provide radiologists greater familiarity with these potentially severe disorders which frequently require intensive in-hospital antibiotic therapy, percutaneous drainage or surgery. Teaching Points • Complicated urinary tract infections occur in patients with structural or functional risk factors.• CT and MRI comprehensively investigate complicated urinary infections and sepsis from unknown sources.• Infections of the urinary bladder, prostate, seminal vesicles, urethra and scrotum are presented.• Emphasis is placed on differential diagnoses of complicated lower urogenital infections.• Unsuspected urinary infections may be detected on CT performed for other clinical reasons.

[Mortality predictive factors in patients with urinary sepsis associated to upper urinary tract calculi]. / Factores predictores de mortalidad en la sepsis urinaria con obstrucción ureteral.

PURPOSE: The aims of this study were to determine the clinical characteristics of patients with urinary sepsis associated to ureteral calculi admitted to the Intensive Care Unit (ICU), and to identify predictors of mortality in the first 24 hours of admission. DESIGN: A retrospective observational study covering a 16-year period (2006-2011) was carried out. SETTING: The combined clinical/surgical ICU of a secondary-level University hospital. PATIENTS: All patients admitted to the ICU due to obstructive urinary sepsis. INTERVENTIONS: None. MAIN VARIABLES: We analyzed general clinical and laboratory test and urological data. The diagnostic technique, affected side, decompression technique, isolated microorganism and antibiotic therapy used were also considered. The assessment of risk factors was performed by multiple logistic regression analysis. RESULTS: A total of 107 patients admitted to the ICU were included in the study, with a mortality rate of 19.6%. The diagnosis was mainly established by ultrasound, and the most commonly used decompression technique was retrograde JJ stenting. Microorganisms were isolated in 48.6% of the patients. In total, 20.6% of the patients had bacteremia. Multivariate analysis found age, acute renal failure and the use of vasoactive drugs administered continuously for the first 24 hours of admission to be independently associated to mortality. CONCLUSIONS: Advanced age, acute renal failure and the need for vasoactive drugs were associated to an increased risk of mortality in patients with urinary sepsis associated to upper urinary tract calculi.

[Emergency nephrectomies: retrospective monocentric study, about eight cases]. / Néphrectomies réalisées dans un contexte d'urgence: étude rétrospective, monocentrique à propos de huit cas.

OBJECTIVE: Emergency nephrectomies are rare because of the improvement of the management of urinary tract infections and the development of radio-embolization. Few series of patients have been reported. The objective of our study is to assess the indication, the morbi-mortality and the outcome of the emergency nephrectomy performed in our hospital. PATIENTS: Between January 2011 and November 2012, eight patients underwent an emergency nephrectomy at the University Hospital Center of Caen. The present review reports the characteristics of this emergency nephrectomy and their morbi-mortality. RESULTS: Six women and two men were analyzed retrospectively between January 2011 and November 2012. All patients except one needed intensive care for a multiple-organ failure. All these eight emergency nephrectomies concerned a native kidney with a surgical approach as a lombotomy or subcostal laparotomy. Both patients survived. One patient need a renal dialysis support. CONCLUSION: Emergency nephrectomy are rare. Uncontrolled urinary sepsis represents the main indication. Identifying the population at risk of evolution to the toxic shock is indispensable for a better and faster care and to reduce the mortality bound to the sepsis.

Factores de riesgo asociados al bajo peso al nacer / Risk factors associated to low birth weight

Se efectuó un estudio de casos y controles de 210 puérperas cuyos hijos nacieron pesando menos de 2 500 gramos (grupo de estudio) en el Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, durante el 2008, para identificar los factores de riesgo asociados al bajo peso al nacer. Los tomados como controles se escogieron a partir de un muestreo aleatorio sistemático por orden de consecutividad en dicho período. Entre los factores de riesgo causantes de ese déficit ponderal figuraron: procedencia rural, ganancia insuficiente de peso materno, período intergenésico menor de 2 años, hipertensión inducida por el embarazo y edad gestacional por debajo de 37 semanas. Las afecciones respiratorias y las infecciones vaginales constituyeron las principales causas de morbilidad; y la sepsis urinaria, de mortalidad.

A case-control study of 210 newly-delivered women whose children were born weighting less than 2 500 grams (study group) was carried out in "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital from Santiago de Cuba, during the 2008, to identify the risk factors associated with low birth weight. The control group was chosen from a systematic random sampling by consecutive order in this period. Among the causative risk factors of that deficit there were: rural origin, low gain of maternal weight, period between pregnancies shorter than 2 years, pregnancy induced hypertension and gestational age under 37 weeks. Breathing disorders and the vaginal infections constituted the main morbidity causes; and the urinary sepsis, the main mortality cause.
