Changes and clinical significance of inflammatory indices in patients with urogenic sepsis with different severity / 中华创伤杂志

Objective:To explore the changes and clinical significance of inflammatory indices of urogenic sepsis with different severity.Methods:A retrospective case-control study was used to analyze the clinical data of 71 patients with urogenic sepsis admitted to 940th Hospital of PLA Joint Logistics Support Force from January 2010 to April 2018, including 34 males and 37 females, aged 39-96 years [(63.1±18.3)years]. The patients were divided into three groups according to the clinical diagnostic criteria for septic shock and sepsis according to the 2014 edition of the Chinese Urology Surgical Guidelines for Diagnosis and Treatment: 21 cases in sepsis group [sequential organ failure assessment (SOFA) score of 3.0 (2.0, 3.0)points], 21 cases in severe sepsis group [SOFA score of 9.0 (6.0, 11.0)points], and 29 cases in septic shock group [SOFA score of 15.0 (14.0, 16.0)points]. Spearman correlation analysis was used to analyze the correlation of inflammatory indicators with SOFA, including white blood cell count, percentage of neutrophils, C-reactive protein, interleukin-6, procalcitonin, fibrinogen, D-dimer, and platelet. Multiple linear regression analysis and stepwise regression weighted analysis were performed to analyze the relation between inflammatory indicators and sepsis severity. Levels of each inflammatory indicator was detected and compared among the groups.Results:① Spearman correlation analysis: percentage of neutrophils, D-dimer, interleukin-6, procalcitonin and SOFA scores were significantly positively correlated, with the r s value of 0.738, 0.712, 0.31, 0.795, respectively ( P<0.01); platelet and SOFA scores were significantly negatively correlated, with the r s value of -0.661 ( P<0.01). ② Multiple linear regression analysis: percentage of neutrophils, platelet, D-dimer, procalcitonin and SOFA score were significantly correlated ( P<0.01); Stepwise regression weighted analysis suggested that the model linear relationship and fit was good. ③ Inflammatory index comparison: percentage of neutrophils in sepsis group, severe sepsis group and septic shock group was 82.30 (76.25, 88.45), 90.50 (86.55, 93.85), 95.10 (92.05, 97.95), respectively; level of platelet was 183.01 (144.50, 246.50)×10 9/L, 149.11 (81.04, 207.00)×10 9/L, 81.26 (50.01, 93.50)×10 9/L, respectively; level of D-dimer was 0.98 (0.71, 1.74)mg/L, 3.45 (1.79, 5.56)mg/L, 7.19 (4.26, 11.63)mg/L, respectively; level of procalcitonin was 0.55 (0.21, 1.09)ng/ml, 5.45 (3.74, 11.80)ng/ml, 17.68 (13.97, 26.75)ng/ml, respectively. There were significant differences in above indicators among the groups ( P<0.05). Conclusions:The serum levels of procalcitonin, percentage of neutrophils, D-dimer and platelet are positively correlated with the severity of urogenic sepsis. While combined detection of those indicators can better predict the severity of the sepsis.

Association of inflammatory indices with the severity of urinary sepsis: analysis of 70 cases / 南方医科大学学报

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 ( < 0.05) but not in CRP (>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 (=0.186, =0.000), N% (=0.047, =0.035) and PLT (=-0.012, =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.

A case report of extensively ossification renal cell carcinoma and review of literature / 中华泌尿外科杂志

Objective To review the pathogenesis, pathology, diagnosis and prognosis of calci-fication or ossification renal cell carcinoma with 1 case report. Methods A 48-year-old man was re-ferred for evaluation of an incidental mass found on the upper-middle right kidney, and computed tomography showed a 7 cm tumor with extensively calcification. PET-CT found an extensively calci-fied and ossification mass without high-function in the upper-middle right kidney. Under the diagnosis of renal cell carcinoma, a transabdominal radical right nephrectomy was performed. Results During the operation, a 7.5 crux 5.0 cm well-circumscribed, encapsulated heterogeneous mass was found on the upper-middle right kidney. The patient underwent an partial nephrectomy. Frozen section diagno-sis was renal cell carcinoma with heterotopic bone formation. Then a transabdominal radical right ne-phrectomy plus regional lymph node dissection were performed. Paraffin sections showed renal cell carcinoma with heterotopic bone formation(clear cell carcinoma, pT2b No M0 ). There was neither me-tastasis nor recurrence during the 8 months follow-up. Conclusions Renal cell carcinoma with ossifi-cation is extremely rare. Renal mass with obvious substantive calcification ossification should be trea-ted as malignant mass before operation. The prognosis of renal cell carcinoma associated with ossifica-tion is relatively good.

Clinical characteristics of adult Wilms' tumor / 中华泌尿外科杂志

Objective To investigate the clinical characteristics of adult Wilms'tumor in Chinese adults and to improve the recognition of adult Wilms'tumor.Methods The clinical data of 6 Wilms'tumor patients treated in our hospital were reviewed. Of them, there were 4 male patients and 2 female patients with mean age of 31 years old. Four patients with abdominal and flank pain and 2 patients with abdominal masses were the main clinical manifestations. One case accompanied with hematuria and another one had fever.Tumor masses were palpable by physical examination in 4 patients. Five patients had percussion tenderness over kidney region and 1 case had abdominal tenderness. Six cases underwent urinalysis and red blood cell was positive in 2 cases. There were no abnormal results in other laboratory tests. Chest X-ray was routinely performed before operation. Six patients underwent ultrasonography and all showed hypoechoic masses (5.0cm×5.0 cm-22.0 cm×25.0 cm) with clear margin. Four cases examined by CT and all had solid masses with inhomogeneous density and clear margin. On enhanced CT scan, 1 of 4 cases demonstrated irregular enhancement of the mass with local hemorrhagic necrosis area. The CT value ranged from 11-40 HU, with an average value of 22.5 HU, and increased to 35-78 HU, with an average value of 63.5 HU after administration of contrast. Two cases of MRI revealed solid mass defects.Three cases underwent IVU examination and showed the enlargement of renal umbra as well as thinning of renal calices caused by the compression of tumor and 1 case showed hydronephrosis.Thus, 5 cases were diagnosed with renal tumor and 1 case was diagnosed with cavitas pelvis tumor before operation. Five patients successfully underwent nephrectomies and 1 patient accepted oophorotomy with no subsequent complication.Retroperitoneal lymph node dissection(RPLND) was performed at the time of radical nephrectomy or oophorotomy in all patients. The tumor was found to be about 5-25 cm in size during operation. One of the tumors had invaded pancreas tail, one had invaded to the lateral abdominal wall and one had invaded into the inferior caval vein. Renal hilar lymph node was found to be exceeded 1.5 cm×1.5 cm in 2 patients. The post-operative incisal surface of the tumor presented with gray-yellow color. Capsule was intact in 4 patients. Three cases had hemorrhagic necrosis in tumor center. All the specimens sent for the pathological examination. None received adjuvant therapy before operation. Four patients received chemotherapy plus radiotherapy after surgery and other 2 patients received chemotherapy only. All patients were followed up with routine lab tests, ultrasonography and chest X-ray.Results Six patients were staged according to the National Wilms'Tumor Study staging system as follows: 1 case in stage Ⅰ, 2 cases in stageⅡ, 2 cases in stage Ⅲ and 1 case in stage Ⅳ. Nephrectomies or oophorotomy were performed in all patients successfully. Tumor diameters were from 4.5-25.0 cm, in average 11.8 cm.All cases had pathological diagnosis of Wilm's tumor. Five cases were classified into favorable histologic type and 1 case was in unfavorable histologic type. Two patients with lymph node metastasis and 3 patients with local invasion were observed. One patient with pulmonary metastasis was recorded. Six patients were followed up for 1-7 years. Five patients survived with no evidence of cancer recurrence. One patient died of pulmonary metastasis 2 years after surgery.Conclusions The majority of adult Wilms'tumors are found with local invasion and metastasis. The incidence of hematogenous metastasis in adult Wilms'tumor is higher than other types of renal tumor as well. The early diagnosis and radical surgical treatment and adjuvant chemoradiotherapy could improve the survival rate.
