Crossed fused renal ectopia: Diagnosis and prognosis as a single-center experience.

J Pediatr Surg 2021 Sep 8;56(9):1632-1637. Epub 2020 Sep 8.

Pediatric Urology Division, Prince Sultan Military Medical City, Riyadh, Saudi Arabia.

Background: Crossed fused renal ectopia (CFRE) is a rare congenital malformation. Renal bladder ultrasound (RBUS) is a good tool for establishing the diagnosis, however, additional imaging with a voiding cystourethrogram (VCUG) and dimercaptosuccinic acid scan (DMSA) might be required. We assessed the need for postnatal evaluation and the long-term consequences in patients with this diagnosis.

Methods: A retrospective review of the records of all patients diagnosed with CFRE between 2004 and 2014 was done. We included all patients who underwent postnatal evaluation with RBUS, DMSA and VCUG. Long-term radiological and functional outcomes were assessed.

Results: A total of 29 patients with CFRE were identified. Majority of cases were detected antenatally (79%) and left to right crossed ectopia constituted the majority of cases (65%). RBUS revealed associated hydronephrosis (HN) in 11 patients (38%). DMSA scans confirmed the diagnosis in all patients and showed impaired renal function in 10 ectopic kidneys (34%). Vesicoureteral reflux was detected in 12 patients (41%); one third of them needed surgical intervention. Extra-urinary anomalies were present in 14 patients (48%) mainly of cardiac origin. After a mean follow-up of 4.5 years, 4 patients (14%) with extra-urinary anomalies developed chronic kidney disease and two of them died.

Conclusions: Crossed fused renal ectopia is commonly associated with both urinary and extraurinary malformations. Postnatal RBUS is usually sufficient for diagnosis, however, additional imaging may aid for confirming the diagnosis and detection of associated urinary anomalies. Presence of extra-urinary malformations with crossed fused ectopia carries a higher risk of morbidity.

Type Of The Study: Retrospective study [diagnostic/prognostic study].

Level Of Evidence: Level IV.

Different managements of horseshoe kidney stones, any difference in the outcome?

Urol Ann 2018 Jul-Sep;10(3):287-290

Division of Pediatric Urology, Department of Urology, Prince Sultan Military Medical City, Riyadh, Saudi Arabia.

Purpose: The aim is to assess the outcomes of different approaches for the management of renal stones associated with horseshoe kidneys (HSKs) in our institution over a 12-year period.

Methods: A retrospective review of 144 patients with HSKs who presented from 2000 to 2012 was performed. Twenty-eight patients (19.4%) were found to have renal stones. Demographic data were collected; the method of treatment and the outcomes of stone management were reviewed. We excluded patients with non-functioning moieties and associated genitourinary anomalies, and those with incomplete data.

Results: We included 25 patients, of which 16 males (64%) and 9 females (36%), with a mean age of 37 years. Mean serum creatinine level was 66 mmol/L. Eleven patients with a stone size <8 mm were treated expectantly with medical treatment, with only one patient requiring endoscopic intervention. Six patients (24%) with a stone size between 1 cm and ≤2 cm were treated with extracorporeal shock wave lithotripsy (ESWL) with the placement of double J stents, and seven patients (28%) with a stone size of >2 cm were treated with percutaneous nephrolithotomy. One patient with a 10 mm stone was treated using flexible ureteroscopy. No significant perioperative complications were encountered.

Conclusions: Indications, methods of treatment, and outcomes of management of stones associated with HSKs were comparable to those for stones associated with normal kidneys. Tailored approach based on stone size is highly recommended. ESWL accompanied with ureteric stenting is a promising strategy for the management of stones associated with HSKs in selected patients requiring intervention.
