Abstract:
ObjectiveTo discuss the characters and management of renal lymphangiectasia.MethodsThe clinical data of two cases of renal lymphangiectasia were reviewed. The first patient was a 37-year-old woman with the chief complaint of lumbago in the right flank for 8 days.B-ultrasound showed mixed echo in perinephric space. On CT, similar appearances of fluid collections were seen, but not conspicuous. Conservative treatment was taken for three weeks and the symptoms were relieved. Three month later the patient had right lumbago relapse. CT scan revealed a large amount of fluid collection under the capsule of the right kidney. Percutaneous drainage was carried out. Two months later B-ultrasound showed fluid collection in perinephric space and percutaneous drainage again the fluid was sent to pathology. The second case was a 32-year-old woman with the chief complaint of lumbago in the left flank for the past three years. Ultrasonography revealed hyperechoic surrounding the left kidney. CT scan showed a left perinephric collection of fluid attenuation and circumferentially draping around the kidney. Renal lymphangioma was diagnosed and the patient underwent surgery.ResultsNeedle aspiration of the perinephric fluid was carried out, and laboratory analysis showed most leucocytes were lymphocytes. The pathologic diagnosis of the first case was renal lymphangiectasia. There was no recurrence during follow - up of two months. The second case was diagnosed renal lymphangioma pathologically. Follow - up for nine years, revealed no relapse.ConclusionsUltrasonography and CT contributed to the diagnosis of renal lymphangiectasia. Needle aspiration bioposy and histology could confirm it. Treatment of asymptomatic cases is not required. When collections are very large and cause symptoms, percutaneous drainage may be carried out however there is a risk of relapse.
