“…The most common type of renal fusion is inferior ectopia with the upper pole of the ectopic kidney fusing with the lower pole of the normal kidney [6]. It seems that left-to-right crossover occurs more frequently [2,6]. Our report describes the uncommon finding of crossed right-to-left inferior renal ectopia with both kidneys placed on the left side of the body associated with proximal ureteral calculus.…”

“…Crossed renal ectopia is one of the rarest urinary tract anomalies, occurring once in every 7500 autopsies or 3078 CT scans [2,3]. The precise mechanism of renal fusion anomalies development is not fully clarified, but ureteral and mechanical theories have been proposed [4].…”

“…Management of urolithiasis in patients with CFRE is technically difficult due to the abnormal position, vascular supply, and relations with surrounding structures. Subsequently, the usual treatment may not be as efficient [2]. Up to today, there is no standardized guideline for the management of upper urinary tract stones in CFRE [6].…”

“…Few studies have reported the treatment of kidney and ureteral calculi with ESWL, percutaneous nephrolithotomy (PCNL), laparoscopic nephrolithotomy (LNL), and retrograde intrarenal surgery (RIRS). An open surgical approach is avoided due to the variability of CFRE forms and associated blood vessel anomalies [2,9]. ESWL is otherwise considered safe and effective in the treatment of stones in almost all parts of the urinary tract, but when it comes to congenital anomalies, the results are contradictory.…”

“…Most individuals have no symptoms in absence of infection and/or urolithiasis, thus CFRE is often incidentally detected. It is associated with an increased rate of stone formation, but also with skeletal, cardiovascular, genitourinary, and gastrointestinal abnormalities [2]. A case of ureteral calculus in a patient with CFRE successfully treated with only one session of Extracorporeal Shockwave Lithotripsy (ESWL) is presented in this report.…”

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.

Retrograde ureteroscopic lithotripsy in cross‐fused renal ectopia

et al. 2021

Introduction Cross‐fused renal ectopia is a rare congenital malformation, and few cases of urolithiasis have been treated by retrograde ureteroscopic lithotripsy. We report a case of urolithiasis in right‐to‐left and superior‐type cross‐fused renal ectopia, successfully treated by the retrograde approach. Case presentation A 69‐year‐old woman with two 14‐mm renal stones in cross‐fused renal ectopia underwent retrograde ureteroscopic lithotripsy. Although we did not recognize the anomaly preoperatively, we could diagnose urolithiasis in the ectopic kidney intraoperatively. The patient had no complication, and follow‐up computed tomography after 3 months showed only a 5‐mm renal stone. Conclusion Although urolithiasis in patients with cross‐fused renal ectopia is a challenging condition for the urologist, the retrograde approach is a safe and effective treatment method. It is necessary to carefully examine the urinary tract especially in a patient with a history of unidentified solitary kidney.

BackgroundCrossed fused renal ectopia (CFRE) is an extremely rare congenital anomaly of the urinary tract that is prone to stone formation. The surgical treatment of CFRE with stones is challenging due to anatomical abnormalities.Materials and MethodsRight kidney stones were treated by flexible ureteroscopic lithotripsy (FURSL) and left kidney stones were treated by robotic surgery.ResultsThe authors present an unreported case of bilateral renal stones in a patient with CFRE, which was successfully treated by robotic pyelolithotomy combined with FURSL. The procedure was manoeuverable, and the stone‐free rate was satisfactory.ConclusionsCFRE with stones (S‐shaped kidney) present a surgical challenge due to anatomical abnormalities and a high stone burden. The authors recommend robotic pyelolithotomy with or without FURSL as a viable treatment option for stones with similar anatomical abnormalities.
