Save Your Only Kidney — Robotic Splenorenal Bypass in India
Dr. Anant Kumar at Max Super Speciality Hospital, Saket, performed India's first robot-assisted splenorenal bypass — a minimally invasive microsurgical procedure that reroutes blood flow to save a single functioning kidney from failure, without open surgery or dialysis.

What is Robot-Assisted Splenorenal Bypass?
A splenorenal bypass is a complex vascular procedure where surgeons disconnect the artery that normally supplies blood to the spleen and reconnect it to the kidney's artery. This creates a "detour" around a severe blockage (renal artery stenosis) to restore healthy blood flow to the kidney.
Using a surgical robot, the surgeon controls miniature instruments with 3D high-definition magnification to stitch these tiny blood vessels together through a few small keyhole incisions — avoiding a large, painful open abdominal cut.
Why this is cutting-edge
Traditionally, fixing a blocked renal artery required either a synthetic vascular graft or highly invasive open surgery — both carrying serious risk for a patient with only one functioning kidney. Connecting the splenic artery directly to the renal artery is technically demanding because the vessels involved are tiny.
Using a robotic platform eliminates hand tremor and adds 3D magnification, allowing for precise suturing with minimal blood loss. This exact robot-assisted approach for a single-kidney patient was reported in May 2026 as the first of its kind in India — a global rarity in organ-sparing vascular reconstruction.
Why patients travel for this
Patients with severe renal artery stenosis and only one functioning kidney face a ticking clock: if the artery closes, irreversible kidney damage follows, making lifelong dialysis or a kidney transplant the only remaining options.
For patients in Africa, the Gulf, the US, or the UK, hyper-specialized robotic vascular urology is either prohibitively expensive, tied to years-long public waiting lists, or simply unavailable locally. Patients travel for this procedure because it actively saves their native kidney, avoids the wait for an organ donor, and sidesteps the recurring cost and quality-of-life toll of dialysis.
The hospital and surgeon
Max Super Speciality Hospital, Saket, New Delhi, India
JCI/NABH-accredited quaternary care facility with a high volume of international medical tourism patients.
Prof. (Dr.) Anant Kumar
Chairman, Urology, Renal Transplant & Robotics, Max Healthcare — 40+ years' experience, 5,000+ kidney transplants, 500+ robotic surgeries.
Dr. Anant Kumar is a world-renowned urologist and robotic surgeon with over 40 years of experience, 5,000+ kidney transplants, and 500+ robotic surgeries, currently Chairman of Urology, Renal Transplant & Robotics at Max Healthcare.
Max Super Speciality Hospital, Saket is a premier, internationally accredited (JCI/NABH) facility with a strong international-patient track record.
The landmark case — a 67-year-old patient mobilized the next day with stabilized blood pressure — is well-documented in Indian medical news. Long-term cohort data on this exact robotic bypass technique is thin given how new it is, but Dr. Kumar's overall robotic kidney surgery outcomes and case volume are heavily published.
What does it cost?
| Region | Estimated Range (USD) |
|---|---|
| India | $5,500 – $8,500 |
| Singapore | $15,000 – $40,000+ |
| United States | $30,000 – $70,000 |
| Kidney transplant in India (for comparison) | $12,000 – $18,000, plus the difficulty of finding a legal matching donor |
| Lifelong dialysis (for comparison) | $15,000 – $90,000+ per year |
Estimated by analogy to current Indian pricing for complex robotic kidney surgeries — exact quotes vary by hospital assessment. Dialysis/transplant comparisons included since that's the real-world alternative most patients are weighing.
What does the journey look like?
Pre-op workup takes 2–3 days: renal doppler ultrasounds, CT angiography to map the blocked vessels, and cardiac clearance. The procedure itself runs 3–5 hours under general anesthesia using the robotic console.
Hospital stay is typically 3–5 days — in the benchmark Indian case, the patient was mobilized the very next day. Plan for 10–14 days of local recovery at a nearby hotel or guest house for blood pressure monitoring and follow-up renal scans confirming healthy blood flow.
Total trip length is approximately 3 weeks in India before flight clearance.
Frequently asked questions
What is a robot-assisted splenorenal bypass?
What is a robot-assisted splenorenal bypass?
It is a minimally invasive surgery that uses a robotic system to reroute the splenic artery to the renal artery, bypassing a severe blockage to restore healthy blood flow to the kidney.
Can this surgery save me from needing dialysis?
Can this surgery save me from needing dialysis?
Yes. If you have a single functioning kidney with severe artery blockage, this procedure restores blood flow, preserving your remaining kidney function and potentially preventing the need for dialysis or a transplant.
Why use a robot instead of traditional open surgery?
Why use a robot instead of traditional open surgery?
Robotic surgery offers 3D magnification and extreme precision for stitching tiny blood vessels, resulting in smaller incisions, less bleeding, faster recovery, and a lower risk of complications compared to open surgery.
Who is Dr. Anant Kumar?
Who is Dr. Anant Kumar?
Dr. Anant Kumar is the Chairman of Urology, Renal Transplant, and Robotics at Max Super Speciality Hospital in New Delhi. He is a pioneer in robotic urology with over 40 years of surgical experience and thousands of successful procedures.
How long will I need to stay in India for this procedure?
How long will I need to stay in India for this procedure?
Plan for a total stay of about 3 weeks — pre-surgery testing, a 3 to 5-day hospital stay, and roughly two weeks of local recovery before flight clearance.
Is it safe to use the splenic artery for the kidney?
Is it safe to use the splenic artery for the kidney?
Yes. The spleen has a robust backup blood supply from other surrounding vessels, so the main splenic artery can be safely detached and repurposed to save the kidney.
