A 32-year-old man consulted Osaka National hospital with chief complaints of dysuria and macrohematuria. DIP and CT revealed that the right kidney deviated to the lower pole of the left kidney and they fused together. The right ureter crossed over the supine. The calcified shadow existed in the lower end of the left ureter with cobra head image. He had no external anomalies. Under diagnosing crossed fused kidney (inverted L shaped) complicated the left ureterocele with a stone, transurethral incision of ureterocele (TUI) was performed. We made transverse incision and extracted stone, 7 mm in size (calcium oxalate 96% and calcium phosphate 4%). Three months later after the operation, IVP, CG and VCG revealed the down-sized ureterocele and no VUR. Crossed renal ectopia complicated many anomalies about 50%. Among them anomalies of the urinary tract was most frequent about 30%. But crossed renal ectopia with ureterocele wasn't reported so far in Japanese literature.
一名32岁男性因排尿困难和肉眼血尿为主诉就诊于大阪国立医院。静脉肾盂造影（DIP）和计算机断层扫描（CT）显示右肾向左肾下极移位并与之融合。右输尿管在前方交叉。左输尿管下端存在钙化影，呈眼镜蛇头样。他没有外部异常。诊断为交叉融合肾（倒L形）合并左输尿管囊肿伴结石，遂行输尿管囊肿经尿道切开术（TUI）。我们做了横向切口并取出结石，结石大小为7毫米（草酸钙96%，磷酸钙4%）。术后三个月，静脉肾盂造影（IVP）、排尿性膀胱造影（CG）和排尿性膀胱尿道造影（VCG）显示输尿管囊肿缩小且无膀胱输尿管反流（VUR）。交叉异位肾合并约50%的多种异常。其中尿路异常最为常见，约占30%。但日本文献中至今尚未报道过交叉异位肾合并输尿管囊肿的情况。
