Haemostatic percutaneousinjection therapy for renal trauma guided by contrast-enhanced ultrasonography

：Objective To studyhaemostatic percutaneous injection therapy for the management of vascular damage inpatients with renal injuries guided by contrast-enhanced ultrasonography(CEUS).MethodsWhich of 56 patients with renal trauma were diagnosis by CEUS,37 cases with grades Ⅱ-Ⅳ renal injuries were brought into our study.According to wound degree andaccompanying active bleeding,they were divided into experiment group (percutaneousinjection hemostatic treatment)and control group(conservative treatment).ResultsThirty-seven renal trauma manifest low perfusion in lesions by CEUS,and the contrast agentcould be seen overflow to renal pelvi and the location of capsule in 13 patients.Thepatients were divided into experiment group(17 cases)and control group(20 cases).The colorof hematuria of 9 patients in experiment group became gradually light at 30 mins aftertreatment.and the color of 7 cases become normal,and hematuria of the only one wasiterative appear.The color of hematuria of 9 patients in control group became graduallylight in 24-72 hours,others' hematuria became gradually light in 5-14 days.The time ofcolor of hematuria become light of the former was shorter than those of thelatter(P<0.05).Reexamination by ultrasound and renal function and urine routine at 1,3and 6 months after treatment,the results of all patients indicated normal.ConclusionsHaemostatic percutaneous injection therapy for renal trauma guided by contrast-enhancedultrasonography has very obvious hemostatic efficacy.Its advantages included may be usedfor effective,minimally invasive control of renal injuries(grades Ⅱ-Ⅳ),and can be a feasible management of active bleeding atbedside.
