Abstract:
Objective To investigate the clinical features,diagnosis and treatment of spontaneous rupture of renal angiomyolipoma (RAML). Methods A total of 23 cases of spontaneous rupture of renal angiomyolipoma were studied retrospectively.The main clinical manifestations were summarized as follows.Sudden and unexpected lumbar and abdominal pain occurred in 21 cases and lumbar swollen pain in 2.Of them 3 cases concomitantly had hematuria.Nausea and vomiting occurred in 2 cases,shock in 3 and fever in 1.All cases underwent B-ultrasonic examination and 21 had CT examination. Results Diagnosis of RAML was established preoperatively in 16 cases,but 4 cases were misdiagnosed for carcinoma of kidney,1 case for renal infectious disease.Two cases were diagnosed by frozen-section sample during operation.Nephrectomy was performed in 10 cases and nephron sparing nephrectomy in 12,and digital subtraction angiography (DSA) embolization in 1. Conclusions Spontaneously ruptured RAML often changes its clinical symptoms and imaging features,which may result in a high misdiagnosis rate and subsequent nephrectomy.Comprehensive analysis of clinical manifestations and image findings can improve preopreative diagnosis rate,and frozen slice sample examination during operation can avoid unnecessary nephrectomy.
