[Infected solitary renal cyst with an intracystic stone: a case report].

A 23-year-old women had a high grade and right CVA tenderness after Caesarean section at another hospital. Because of these symptoms, she was eventually transferred to our university hospital, where she was treated with antibiotics. However, both the high grade fever and right CVA tenderness persisted. We conducted IVPs in order to determine the cause of the fever. Deformities of the right upper calyceal system were consequently discovered. We then performed sonographic examination, CT-scan and percutaneous cystography which revealed a right infected solitary renal cyst with an intracystic stone. An operation revealed no apparent communication between the renal cyst and calyceal system. Histological examination of the surgical specimens revealed the presence of inflammatory change. The postoperative course was uneventful and the patient was discharged.
