RESUMEN
【Objective】 To investigate the safety and efficacy of flexible vacuum aspiration ureteral access sheath in ureteroscopic lithotripsy in the treatment of renal and upper ureteral calculi. 【Methods】 Clinical data of 41 cases treated in our hospital were retrospectively analyzed, including 20 cases treated with flexible vacuum aspiration ureteral access sheath (experimental group), and 21 cases treated with traditional ureteral access sheath (control group). The stone-clearance rate, operation time, postoperative fever (T>37.5 ℃), length of hospital stay and hospitalization costs were compared between the two groups. 【Results】 All operations were successful. The experimental group had significantly shorter operation time than the control group [(54.0±19.8) min vs. (76.6±20.1) min, P0.05). 【Conclusion】 Flexible vacuum aspiration ureteral access sheath in flexible ureteroscopic lithotripsy can shorten the operation time, improve stone-clearance rate and reduce incidence of postoperative fever, which is worth promoting.
RESUMEN
Renal subcapsular abscess(RSA) is a rare disease with unknown etiology and pathogenesis. CT is an important assistant examination for the diagnosis. In this study, we reported 2 cases of RSA. One case achieved good therapeutic effect by timely debridement and surgery drainage, and the other case refused to perform debridement and drainage, which lead to the death. This kind of disease develops quickly and progresses rapidly. The adequate debridement and surgery drainage are important in treating this disease.
RESUMEN
Spontaneous renal artery dissection is a rare disease with unknown etiology, confounded clinical manifestations, and easy to be misdiagnosed as urinary tract infection. The diagnosis mainly depends on imaging examinations. Intravascular interventional therapy is a safe and effective treatment. This study reported a case of spontaneous renal artery dissection , which treated by intravascular interventional therapy of renal artery , and had achieved good therapeutic effect.
RESUMEN
Objective To explore the clinical application value of the detection of sIgE and sIgG4 in children with allergic asthma and allergic rhinitis .Methods The levels of sIgE and sIgG4 of allergic asthma group (n=85) ,allergic rhinitis group (n=72) and control group (n=60) were respectively detected by ELISA .The diagnostic efficiency of sIgE and sIgG4 were analyzed by using ROC curve .Results Before treatment ,the serum levels of sIgE and sIgG4 of allergic asthma group and allergic rhinitis group were remarkably higher than those of control group (P< 0 .01) .After 6 -month treatment ,the serum sIgE levels of allergic asthma group and allergic rhinitis group significantly decreased ,and the serum sIgG4 levels significantly increased (P< 0 .01) .For the combined detection of sIgE and sIgG4 ,the diagnostic sensitivities of allergic asthma and allergic rhinitis were 90 .6% (77/85) and 84 .7% (61/72) respectively ,and the diagnostic specificities of allergic asthma and allergic rhinitis were 81 .2% (69/85) and 76 .4%(55/72) respectively .Conclusion The serum sIgE and sIgG4 are good indicators for the diagnosis of allergic diseases .
RESUMEN
Objective To explore the role of chemokine CCL18 in the occurrence and development of children allergic diseases. Methods The serum levels of CCL18 in 87 children cases of allergic asthma,64 cases of allergic rhinitis,46 cases of allergic con-junctivitis and contemporaneous 50 health students with physical examination as the control group were measured by ELISA and re-measured after 6-month treatment.The detection results were statistically analyzed with combining the clinical related detection data by adopting SPSS18.0 statistical software and t-test.Results The serum levels of CCL18 in the children allergic asthma,allergic rhinitis and allergic conjunctivitis groups were remarkably higher than those in the control group with statistical differences(P <0.05);the levels of CCL18 in the severe groups were remarkably higher than those in the mild and moderate groups with statistical difference(P <0.05);the levels of CCL18 after 6-month treatment in 3 groups were significantly decreased compared with before treatment with statistical difference(P <0.05).Conclusion The serum level of CCL18 is significantly associated with the severity of illness and significantly decreased after treatment,which indicating that the CCL18 detection has the important value in the diag-nosis,severity evaluation and treatment effect monitoring of children allergic diseases.
