Many people find out about a kidney tumor almost by accident — during a scan done for something else entirely. That sudden, unplanned news can be disorienting. At Zanish Cancer Hospital in Ahmedabad, Dr. Nishant Sanghavi and team offer robotic-assisted kidney cancer surgery as one of the treatment options for renal tumors, with a focus on removing the cancer while preserving as much healthy kidney tissue and function as the case allows.
Robotic kidney cancer surgery uses a robotic-assisted surgical system to remove a kidney tumor through a handful of small incisions, instead of one large open cut across the abdomen or flank. The surgeon sits at a console and directs every instrument movement in real time, guided by a magnified 3D view of the kidney and surrounding structures.
There are two broad surgical approaches, and which one applies to you depends entirely on the tumor: a partial nephrectomy removes just the tumor and a margin of surrounding tissue, leaving the rest of the kidney intact, while a radical nephrectomy removes the entire kidney when the tumor’s size or location makes that necessary. Robotic technology is used for both, but it’s particularly valued in partial nephrectomy, where the fine control it offers helps surgeons work close to blood vessels and the kidney’s collecting system without needing a large incision.
Where possible, keeping as much functioning kidney tissue as safely achievable is a real clinical priority — not just a nice-to-have. Long-term kidney function affects overall health well beyond the cancer itself, particularly for patients who already have reduced kidney function, diabetes, high blood pressure, or only one working kidney.
This is exactly where robotic precision tends to help most. The improved visualization and control can make it more feasible to remove a tumor with a clean margin while sparing surrounding healthy tissue — something that’s technically more demanding with open surgery. That said, whether partial nephrectomy is possible depends on the tumor’s size, depth, and position relative to the kidney’s blood supply and drainage system, not on the surgical approach alone. Dr. Sanghavi will explain what’s realistic for your specific scan findings before recommending a plan.
Compared with traditional open kidney surgery, the robotic approach typically involves:
As with any surgery, individual outcomes depend on the tumor’s characteristics, your overall health, and prior abdominal surgeries you may have had — all of which Dr. Sanghavi reviews before advising on the best surgical approach for you.
Patients with localized renal tumors — cancer confined to the kidney or with minimal spread beyond it — are generally considered for robotic surgery, provided they’re medically fit for general anesthesia. Very large tumors, those involving major blood vessels, or certain complex anatomical situations may be better suited to open surgery instead, and that’s a judgment made case by case using your imaging.
For smaller, low-risk tumors, surgery isn’t always the immediate answer either — active surveillance is sometimes appropriate, particularly for older patients or those with significant other health conditions. Dr. Sanghavi’s team reviews your full picture, including CT or MRI imaging and kidney function tests, before recommending a path.
Before surgery: Your workup usually includes cross-sectional imaging (CT or MRI) to map the tumor precisely, blood tests to check kidney function, and a pre-anesthesia fitness review. This is the right time to ask about whether partial or radical nephrectomy applies to your case.
During surgery: Performed under general anesthesia, the procedure generally takes a few hours depending on tumor complexity, through several small abdominal incisions.
After surgery: Most patients are in hospital for a few days, with pain typically well-controlled and manageable compared to open surgery. Kidney function is monitored closely afterward, and your care team will explain what follow-up imaging and blood work to expect over the following months.
Two questions come up often: “Will I need dialysis?” and “Will my remaining kidney be enough?” For most patients undergoing partial nephrectomy, one healthy kidney — or even a well-preserved portion of one — provides sufficient function for normal life, and dialysis is not a routine outcome of this surgery. For radical nephrectomy, the remaining kidney typically compensates over time in patients who start with normal kidney function, though this depends on individual health factors that are assessed beforehand. These specifics are discussed directly during consultation, based on your own kidney function tests, rather than given as a general reassurance.
Dr. Nishant Sanghavi is a surgical oncologist with over 16+ years of experience and more than 6,000 cancer surgeries performed, practicing at Zanish Cancer Hospital in Naranpura, Ahmedabad, where he has served as Director and Consultant Surgical Oncologist since March 2018. He completed his MBBS at Smt. NHL Municipal Medical College, Ahmedabad (2006), his M.S. in General Surgery at Smt. NHL Municipal Medical College, Shardaben Hospital (2010), and his M.Ch in Surgical Oncology at the Gujarat Cancer and Research Institute (GCRI), Civil Hospital, Ahmedabad (2014).
He trained further in advanced laparoscopic oncosurgery under Dr. Shailesh Putambekar at Galaxy Care Institute, Pune, and has served as Conference Director and Chairperson at national oncology forums, including the Thoracic and Colorectal Oncology Summit (TACOS) 2026 in Ahmedabad.
His surgical focus includes uro-oncology — covering renal cell carcinoma and other urological malignancies — alongside GI oncology, gynecologic oncology, head & neck oncology, breast cancer surgery, and soft tissue sarcoma.

The cost of robotic kidney cancer surgery depends on the type of nephrectomy needed, tumor complexity, hospital stay duration, and any additional treatment required. Rather than quoting a one-size-fits-all figure, our team provides a personalized estimate during consultation and can explain insurance and Mediclaim coverage where applicable.
If you’ve had a kidney mass flagged on a scan or already received a treatment recommendation elsewhere, a second opinion is a reasonable next step — not a sign of doubting your existing care. Dr. Sanghavi reviews your imaging and reports to discuss whether robotic surgery, a different surgical approach, or active surveillance fits your situation.
Zanish Cancer Hospital is located on the 1st Floor, Viva Atelier, Opp. B.D. Patel House, Near Sardar Patel Statue, Naranpura, Ahmedabad, serving patients across Ahmedabad and Gujarat, including SG Highway, Bodakdev, Satellite, and Prahlad Nagar, as well as international patients traveling from the USA, UAE, and UK.

Colon cancer surgery removes part of the colon and typically reconnects the bowel in the same operation. Rectal cancer surgery is performed deeper in the pelvis, often involves pre-surgical chemoradiation, and more frequently requires a temporary stoma.
Yes — robotic techniques are well established for both, though the specific operation performed differs based on tumour location.
Yes — it’s a well-established approach with the surgeon in full control throughout. Individual risks vary by procedure and are discussed in detail at consultation.
This is determined by your colonoscopy and biopsy findings, based on the tumour’s exact location within the large intestine. Your surgeon will clarify this early in your evaluation.
Cost varies depending on whether the procedure is for colon or rectal cancer, and the extent of surgery involved. Book a consultation for a personalised estimate.
