Renal Tumours: A Case Study


Abhishek Guha (name changed on grounds of anonymity), aged 52, had no idea that he had been nursing a golf-ball-sized tumour in his kidney when he went for the regular health check-up organised by his company. A simple Ultrasonography (USG) revealed the tumor and he soon found himself seated in front of Dr Amlan Chakraborty, Consultant Urologist at The Calcutta Medical Research Institute (CMRI). Dr Amlan Chakraborty shared, that renal tumours are the 8th most common cancers and usually more common in men above the age of 50. They have no established connection to diet or lifestyle and may have some hereditary causes.

The Ultrasonography (USG), which was administered to the patient, is the most common method of screening for renal tumours and sometimes shows symptoms like blood in urine or a lump in the abdomen. Abhishek Guha had no such symptom and therefore his tumour at the time of the start of treatment had grown to 10 X 8 X 7 cm3 and was critically positioned, thus making it extremely complicated to operate and remove.

Unfortunately, renal tumours cannot be treated through medication and surgery is the only way of managing them.

The treatment of renal tumours can be approached in two different ways, depending on the size and position of the tumour.  If the tumour is small, detected early and favourably placed in the kidney, it can be extracted from the body through a minimally invasive procedure (laparoscopy) called the nephron sparing surgery or laparoscopic partial nephrectomy. Complications arise when the tumour is big and critically placed in the kidney – as was the case with Abhishek Guha.

According to Dr Amlan Chakraborty, “When a patient comes to us with a malignant renal tumour, our primary focus is the complete removal of cancer cells from the body.
Prior to the great advancements in minimally invasive surgical procedures, a case like Abhishek Guha’s would be treated through an invasive open surgery. Open surgeries pose more complications, have higher risk and lesser accuracy. Moreover, handling of cancerous tumours may cause spillage of cancer cells to other parts of the body. Therefore, the
most efficient way, which has emerged as a result of advanced medical treatment, is to choose a minimally invasive procedure like the Laparoscopic Radical Nephrectomy.”


Laparoscopic radical nephrectomy provides patients with a safe and minimally invasive technique for complete removal of the affected kidney and tumour.


The HD camera Laparoscope allows a 4X magnification of the operative field. This, along with other state-of-the-art equipment used at CMRI allows the surgeons to accomplish the operative procedure with improved vision and without placing their hands inside the abdominal cavity.

Abhishek Guha’s surgery was completed in 3 hours and he was home in 4 days. He was in a condition to resume work in 10 days from leaving the hospital.


Dr. Amlan Chakraborty, Consultant Urologist at The Calcutta Medical Research Institute, says, “Minimally Invasive procedures like the Laparoscopic Radical Nephrectomy allows for improved cosmesis, reduced pain, blood loss and hospital stay as compared to open surgeries. CMRI’s use of latest energy sources, imaging systems, HD cameras and harmonics has taken the field of Uro-oncology to the next level in Eastern India.”
