Hyderabad, July 17th, 2026: In a remarkable demonstration of advanced paediatric urological surgery, doctors at the Asian Institute of Nephrology and Urology (AINU), Hyderabad, successfully removed a kidney tumour from a six-year-old boy, native of Hyderabad, born with one of the rarest congenital kidney abnormalities _ a crossed fused ectopic kidney _ using a highly specialised minimally invasive laparoscopic procedure. The surgery preserved the child’s healthy kidney tissue and function despite the exceptionally complex anatomy.
The child was brought to AINU after passing blood in his urine for two days. Detailed investigations revealed a tumour arising in a crossed fused ectopic kidney, an uncommon congenital condition in which both kidneys are fused together and located on the same side of the body. Such anomalies are extremely rare and present a formidable surgical challenge because the kidneys possess distorted collecting systems and an unpredictable network of blood vessels, making conventional surgical approaches risky.
To overcome these challenges, the surgical team employed advanced three-dimensional imaging before the procedure to meticulously map the child’s unique vascular anatomy and plan a customised surgical strategy. During surgery, laparoscopic intraoperative ultrasound was used to accurately identify the exact location, depth and margins of the tumour within the fused kidney.
The cutting-edge imaging technologies allowed surgeons to selectively control only the tumour-feeding blood vessels and remove the tumour through tiny keyhole incisions while preserving blood flow to the remaining healthy kidney. The tumour was excised completely with clear surgical margins, the child experienced no major complications, retained normal kidney function and made a smooth recovery before being discharged in good health.
Commenting on the rate condition and the surgery, Dr. Syed Md. Ghouse, Director – Robotics and Minimal Access Urology, AINU, who led the surgical team said, “ Operating on a tumour in a crossed fused ectopic kidney is among the most demanding procedures in paediatric urology because every patient’s anatomy is unique and conventional surgical landmarks are absent. Success in such cases depends on meticulous planning and the intelligent use of advanced technologies. Three-dimensional reconstruction, intraoperative ultrasound and ICG fluorescence imaging allowed us to precisely identify the tumour and preserve the healthy kidney, giving the child the best possible long-term outcome while avoiding the trauma of open surgery.”
Speaking about the procedure *Dr. Mallikarjuna C, Managing Director, Chief Consultant Urologist & Robotic Surgeon, AINU said, “Managing tumours in a fused kidney is exceptionally complex due to the abnormal anatomy and shared blood supply. Using advanced keyhole surgical techniques, we were able to precisely remove the tumour while preserving maximum kidney function—something that is critical, especially in such rare cases.”
Doctors at AINU said the successful outcome highlights how modern minimally invasive surgery, when combined with surgical expertise, can safely treat even the rarest and most anatomically challenging paediatric kidney tumours while preserving organ function. The case also reinforces the growing role of precision-guided surgery in improving outcomes for children with complex congenital urological disorders.
A rare ‘fused kidney’ with a complex tumour was successfully treated using advanced keyhole surgery by a multidisciplinary team comprising Dr. Syed Md. Ghouse, Director – Robotic & Minimal Access Urological Surgery; Dr. Mallikarjuna C, Managing Director & Chief Consultant Urologist and Robotic Surgeon; and Dr. Rajesh Kumar Reddy Adapala, Consultant Uro-Oncologist.
