Crossed fused renal ectopia (CFRE) is a rare congenital abnormality of the urinary tract where the kidneys are fused on one side, while the ureter of the ectopic kidney crosses the midline with the normal entrance in the bladder on the contralateral side. Congenital anomalies are associated with a stone formation whose management represents a real challenge. To our knowledge, we report the second case of CFRE associated with ureteral stone, which has been successfully resolved with Extracorporeal Shockwave Lithotripsy (ESWL) and the first of its kind where a sufficient degree of stone disintegration has been achieved after a single session with a complete stone clearance during the follow-up. Radiological examination showed an inferior type of CFRE with stone in the proximal part of the ureter of the upper kidney. ESWL is an acceptable and effective treatment option in CFRE patients due to the minimally invasive approach, potentially high stone-free rate, and rare complications.
交叉融合肾异位（CFRE）是一种罕见的先天性泌尿系统异常，即双侧肾脏在一侧融合，而异位肾的输尿管越过中线，在对侧膀胱正常开口处进入。先天性异常与结石形成有关，其治疗是一项真正的挑战。据我们所知，我们报告了第二例与输尿管结石相关的CFRE病例，该病例已通过体外冲击波碎石术（ESWL）成功解决，并且是首例在单次治疗后结石达到足够破碎程度并在随访期间结石完全清除的病例。影像学检查显示为下型CFRE，上肾输尿管近端有结石。由于微创方法、潜在的高结石清除率和罕见的并发症，ESWL是CFRE患者可接受且有效的治疗选择。
