At Postpartum, a 29-year-old female was presented right upper quadrant mass. Abdominal ultrasonography showed marked hydronephrosis in the right kidney. IVP showed nonvisualization in the right kindey and inward axis in the left kidney. RGP showed that right ureter was well visualized but right pelvocalyceal system was faintly visualized. DTPA renal scan showed true obstruction in the right kidney, At operation, 7 x 8 cm sized cystic mass was founded behind the right pelvis. Aspiration of cystic mass showed dark-reddish colored fluid and the frozen biopsy of cystic wall showed renal cell carcinoma. And we took right radical nephrectomy and isthmectomy. The permanent biopsy of resected mass showed cystic renal cell carcinoma in horseshoe kidney( stage I, grade II, clear cell type).
