Abstract:
ObjectiveTo investigate the clinical features and ultrasound imaging characteristics of retroperitoneal fibrosis (RPF),and to find out the value of ultrasound in monitoring the outcome of this disease.MethodsTwelve patients with retroperitoneal fibrosis proven by operation or biopsy were analyzed retrospectively.Their abdominal ultrasound images before and after treatments were studied,especially the severity of renal collecting system separation,the abnormal echo group around the retroperitoneal organs which including the abdominal aorta,the mesenteric artery and vein,the iliac vessels,the inferior vena cava,the bilateral ureters,renal arteries and veins.ResultsAll patients had abnormal separation in renal and ten patients were detected corresponding dilatation in unilateral or bilateral ureters.Seven patients were detected hypoechoic and heterogeneous clumps located in retroperitoneal area,which were around retroperitoneal blood vessels,kidneys or ureters.Three patients received resection to rule out cancer,two patients had ultrasound-guided biopsy and took hormone therapy after diagnosis,seven patients undertook ureteral release surgery and inserted double J stent combined with hormone therapy.Two months later,ultrasound showed the lesions significantly disappeared or reduced size compared with before treatments.It was also found that the majority of patients had hydronephrosis relieved and renal function recovered.Conclusions Ultrasound can help diagnosing retroperitoneal fibrosis,and monitor the outcome of this disease.
