Landmark 8-Hour Surgery to Remove Largest Kidney Tumour

Hyderabad, India – April 16, 2026

In a historic milestone in advanced urologic oncology, the Urology surgical team at Continental Hospitals, Hyderabad, successfully performed a complex radical nephrectomy to remove an exceptionally large left kidney tumour measuring 25 × 16 × 18 cm and weighing approximately 4 kg, making it one of the largest kidney cancers ever resected. The high-risk surgery, conducted on April 15, 2026, lasted an intense 8 hours, requiring extraordinary precision, endurance, and seamless multidisciplinary coordination.

The Urosurgical team was led by Dr. Kanishka Kumar (MCh Urology), with Dr. Sravan (MCh Urology) playing a major and integral role in the surgical team. Preoperative imaging revealed a massive renal mass occupying a significant portion of the left abdominal cavity, displacing adjacent organs and closely abutting major vascular structures. The sheer size and complexity of the tumour posed formidable surgical challenges,

including risk of major blood loss, difficulty in mobilization, and the need for meticulous dissection.

“This was an extraordinarily demanding case due to the tumour’s massive size, weight, and anatomical complexity,” said Dr. Kanishka Kumar. “The surgery required sustained focus over 8 hours, precise vascular control, and a highly coordinated team effort to ensure safe and complete tumour removal.”

The procedure involved complete removal of the affected kidney along with the tumour, ensuring optimal oncological clearance. Despite the complexity, the surgery was successfully completed without major intraoperative complications. The patient is currently recovering well under close postoperative monitoring, with stable vital parameters and encouraging early recovery.

Such massive renal tumours are exceedingly rare in modern clinical practice, as most kidney cancers are diagnosed at earlier stages due to widespread use of advanced imaging techniques. This case stands as a testament to the surgical expertise and advanced infrastructure at Continental Hospitals, enabling the management of rare and highly complex oncologic cases.
