Extremely complex tumour removal surgery performed at Riga East University Hospital: 21-kilogram tumour surgically removed 

A patient recently underwent a highly complex surgery at the Oncology Centre of Latvia at Riga East University Hospital (Riga East Hospital) to remove a massive tumour from the right kidney and restore the function of the affected organs. The patient had a 21-kilogram tumour removed, which is the heaviest tumour ever excised at Riga East Hospital and, most likely, in Latvia. Previously, the heaviest tumour was a 15-kilogram sarcoma excised at the Oncology Centre of Latvia in January 2020. 

“The patient’s condition became critical in a relatively short period of time. The tumour started to grow very rapidly, affecting not only his health, which deteriorated, but also his quality of life,” says Kārlis Pētersons, Chief Physician in Oncological urology at the Clinic of Urology and Oncological Urology of Riga East Hospital, describing the patient’s condition.

The 66-year-old patient came to the attention of doctors at the Clinic of Urology and Oncological Urology because of an abdominal injury that led to a computed tomography scan of the abdomen, which revealed a mass near the right kidney. The patient reported that the lump initially seemed encapsulated, but in recent months it began to grow rapidly. This caused significant discomfort, restricted movement, and made it difficult to get around. Although the patient’s overall weight was increasing, he was also rapidly getting weaker and becoming increasingly frail.

After examining the patient, Associate Professor Armands Sīviņš, Head of the Oncosurgery Clinic at the Oncology Centre of Latvia of Riga East Hospital, concluded, “The patient urgently needs surgery to remove the tumour. However, this procedure is highly challenging, as it involves the delicate separation and removal of a large tumour and carries a significant risk of intraoperative and postoperative complications.” The surgery lasted five hours, and the doctor emphasised that “it was performed relatively quickly”. It went well and without any major complications.

Sīviņš explains: “After the surgery, we found that the tumour weighed 21 kilograms and had compressed almost all the patient’s vital abdominal organs and major blood vessels. During the surgery, in addition to removing the tumour, we had to surgically remove the patient’s right kidney and adrenal gland, a large portion of the right diaphragm, and connect the left residual renal vein to the vena cava.” I have to say that the patient’s other kidney is now working at full capacity, or even double duty, which is very good.”

The post-operative period was difficult – the patient spent 11 days in intensive care – but he is recovering well. “I am very pleased with this collaborative effort, because we were able to help a patient. I believe that the most important thing is the cooperation of a professional team, where everyone does their job selflessly,” summarises doctor A. Sīviņš.

The surgery was performed by a team of doctors of the Riga East Hospital:

– Head of Oncosurgery Clinic of the Oncology Centre of Latvia, asoc. prof. Armands Sīviņš

– Chief physician of the Clinic of Urology and Oncological Urology in Oncological Urology Kārlis Pētersons;
