In an extraordinary testament to the advanced capabilities and unwavering dedication characterizing the medical profession in Sri Lanka, a distinguished team of military and civilian healthcare specialists has etched its name into global medical history. Led by Consultant Urologist Lieutenant Colonel (Dr) Kugadas Sutharshan at the Colombo Army Hospital, the surgical team successfully excised the largest and heaviest kidney stone ever documented in medical literature, thereby securing an official Guinness World Record. This monumental achievement not only highlights the exceptional clinical acumen harboured within the nation’s healthcare institutions but also reinforces Sri Lanka’s standing on the international stage as a centre of medical excellence and surgical precision.
A Historic Medical Intervention at Colombo Army Hospital
The unprecedented surgical procedure, performed on the 1st of June, involved a 62-year-old retired military serviceman named Canistus Coonghe, who had presented with severe renal complications. Upon thorough diagnostic evaluation, medical professionals discovered an astonishingly massive nephrolithiasis obstruction that defied conventional medical expectations regarding human anatomy and physiological tolerance. Recognizing the extreme complexity and inherent risks associated with such an advanced pathological formation, a multidisciplinary surgical team was swiftly assembled under the auspices of the Colombo Army Hospital’s Genito-Urinary Unit.

The operation demanded meticulous precision, profound anatomical expertise, and seamless collaboration among senior specialists. Alongside Lieutenant Colonel (Dr) Kugadas Sutharshan, the surgical team comprised Captain (Dr) WPSC Pathirathna and Dr Thamasha Premathilaka, both of whom played instrumental roles throughout the intricate intervention. Furthermore, the critical administration and maintenance of patient stability during the prolonged procedure were expertly managed by Consultant Anaesthetists Colonel (Dr) UALD Perera and Colonel (Dr) CS Abeysinghe. Their combined efforts culminated in the flawless execution of an operation that was previously deemed medically prohibitive due to the sheer scale of the anomaly.
Quantifying the Record-Breaking Anomaly
Upon successful extraction, rigorous physical measurements were conducted under stringent clinical supervision to document the specimen’s exact dimensions and mass. Official evaluations verified that the colossal renal calculus measured an astonishing 13.372 centimetres in length and weighed a staggering 801 grams. To contextualise the magnitude of this achievement, an average adult human kidney typically measures approximately 10 to 12 centimetres in total length, meaning that the excised stone was substantially larger than the organ itself, a physiological marvel that left international medical observers astounded.

Prior to this momentous occasion, the previous Guinness World Record for the largest kidney stone was held in India since 2004, measuring 13 centimetres, while the heaviest recorded stone weighed 620 grams, recorded in Pakistan in 2008. By surpassing both historical benchmarks simultaneously in terms of length and weight, the Sri Lankan medical team has not merely broken existing records; they have redefined the boundaries of what is surgically achievable in complex urological care.
The Broader Implications for Sri Lankan Healthcare
This extraordinary accomplishment serves as a powerful reminder of the resilience, innovation, and high standard of training prevalent within Sri Lanka’s healthcare infrastructure. Despite various economic and infrastructural challenges faced by the nation in recent years, the medical fraternity continues to deliver world-class clinical outcomes, driven by a deep-seated commitment to patient welfare and scientific advancement.
The global Sri Lankan community, spanning across Australia, the United Kingdom, Canada, New Zealand, and beyond, has received this news with immense national pride and admiration. Such milestones illuminate the boundless potential inherent within domestic institutions when exceptional talent is coupled with rigorous dedication. As stories of these remarkable triumphs resonate internationally, they inspire future generations of healthcare professionals across the island to pursue excellence with unwavering resolve.
