Robotic Partial Nephrectomy in London
Mr Sri performs retroperitoneal robotic partial nephrectomy at HCA Princess Grace Hospital, Marylebone — one of London's foremost private surgical facilities, steps from Harley Street. For patients in Central, North, or East London, and for international patients, Princess Grace provides world-class robotic kidney cancer surgery without the need to travel south of the river.
Same-week consultation appointments are routinely available. Surgery is scheduled at your convenience with no waiting list. No GP referral required.
Complex kidney surgery at the heart of London's medical district
HCA Princess Grace Hospital sits at 18 Devonshire Street, W1 — one minute from Harley Street, five minutes from Regent Street. It operates a dedicated robotic surgical theatre with the da Vinci system and is widely used by consultants from London's major teaching hospitals for complex oncological surgery in their private practice.
For patients in Central, North, or East London — and for international patients coming to London for specialist treatment — Princess Grace eliminates the need to travel to South West London while providing access to the same retroperitoneal robotic partial nephrectomy programme Mr Sri has introduced as the regional standard of care.
The hospital has an established international patient pathway: concierge service, interpreter support, proximity to major West End hotels, and straightforward access from Heathrow via the Elizabeth line and from St Pancras for European visitors. Consultations, pre-operative assessments, and post-operative appointments can all take place in Marylebone.

The retroperitoneal approach — why it matters to your recovery
Most robotic kidney surgery is performed through the abdomen (transperitoneal), requiring the bowel to be moved to reach the kidney. Mr Sri approaches the kidney directly from behind — the retroperitoneal route — without entering the abdominal cavity at all. This distinction has meaningful consequences for patients.
Mr Sri introduced this technique to South West London, performs it as his default approach for the majority of cases, and has published on this technique in the Journal of Robotic Surgery. He is one of a small group of European surgeons operating at this volume retroperitoneally.
The numbers behind the practice
These figures represent an audit of Mr Sri's personal robotic partial nephrectomy series as of end 2025.
Treating the full complexity spectrum
Mr Sri accepts tertiary and quaternary referrals for tumours declined for nephron-sparing surgery elsewhere — including from other London hospitals. His case mix reflects one of the most complex partial nephrectomy practices in the UK.
| RENAL Score | Complexity | Proportion of series |
|---|---|---|
| Score <7 | Low | 8% |
| Score 7–9 | Intermediate | 44% |
| Score >10 | High | 48% |
Median tumour size 3.2cm (range 1.5–9.0cm). 32% of tumours >4cm.
Told your tumour can't be preserved?
A significant number of patients seen at Princess Grace have been assessed — and declined for kidney-preserving surgery — at other London hospitals. Mr Sri accepts these quaternary referrals and reviews each case on its merits. The conversion to radical nephrectomy rate in his series is 0.3%.
Patients who have received a recommendation for radical nephrectomy, or who are on active surveillance and wish to discuss whether surgery is appropriate, are welcome for a second opinion consultation at Princess Grace. No GP referral is required.
Why saving your kidney matters beyond the operation
Removing a kidney tumour while preserving the rest of the kidney is the standard of care recommended by the European Association of Urology (EAU) for the majority of renal masses where it is technically feasible. The evidence for long-term patient benefit is substantial and independent of cancer control.
Every functioning nephron preserved contributes to glomerular filtration rate (GFR). Chronic kidney disease (CKD) — which results from reduced nephron mass after radical nephrectomy — is independently associated with increased cardiovascular mortality, accelerated hypertension, and the need for dialysis. Partial and radical nephrectomy achieve equivalent cancer control for most kidney tumours: the long-term outcome difference lies in kidney and cardiovascular health over decades following surgery.
Mr Sri's commitment to nephron-sparing surgery extends to the most technically demanding cases — including large, endophytic, and hilar tumours where many surgeons default to radical nephrectomy. His trifecta and pentafecta data confirms this approach can be delivered safely even in high-complexity cases.
EAU guidelines state that nephron-sparing surgery should be performed for all T1 renal masses where technically feasible, and strongly considered for T2 tumours where expertise allows.
Radical nephrectomy is reserved for cases where partial nephrectomy cannot be performed safely without compromising oncological control.
