[New surgery for complicated renal anomalies]

Area of Science:

• Urology
• Pediatric Surgery
• Nephrology

Context:

• Conventional surgical techniques are insufficient for complex renal anomalies.
• Complicated renal anomalies, including horseshoe kidney and kidney malrotation, present significant surgical challenges.
• Existing methods fail to address the multifaceted causes of these complications.

Purpose:

• To broaden the indications for ex vivo surgery and autotransplantation.
• To present a novel surgical strategy for complex renal anomalies.
• To address the simultaneous pathology of renal anomalies and their excretory tracts.

Summary:

• Ex vivo surgery and autotransplantation were employed in 14 cases of distinct complicated renal anomalies.
• The technique involves correcting abnormal kidney orientation and position, resecting dysplastic excretory tracts, and ensuring normal urinary drainage.
• Thirteen out of fourteen operated cases achieved excellent results, demonstrating successful renal parenchyma conservation.

Impact:

• This innovative surgical method offers a resolution for complex kidney malformations.
• The study presents the first documented surgical method and long-term outcomes for ex vivo kidney surgery in both adult and pediatric patients.
• Successful outcomes highlight the potential to resolve difficult issues in congenital kidney malformations.
