For GPs, consultants and specialist nurses
Referring a patientis simple
Private referrals across urology, with a subspecialty focus on robotic kidney and prostate cancer surgery. Rapid access, prompt clinic letters, and complex cases welcomed from across the UK.
Three ways to refer
The private office contacts your patient within one working day to arrange an appointment.
Email a referral
Send the referral letter, MDT outcome and imaging reports. Include your contact details for the clinic letter.

The full breadth of urology, with particular depth in uro-oncology and robotic surgery.
Kidney cancer and renal masses
Refer for: incidental renal mass, haematuria with flank pain, CT-confirmed lesion, complex cystic lesions.
Management: retroperitoneal robotic partial nephrectomy as standard, radical nephrectomy where needed. High RENAL score and solitary kidney cases accepted, including those declined for nephron-sparing surgery elsewhere.
Suspected or confirmed prostate cancer
Refer for: raised PSA, abnormal DRE, MRI-detected lesion, post-biopsy diagnosis.
Management: mpMRI and targeted transperineal biopsy, then Retzius-sparing or standard nerve-sparing RARP. All risk groups, including high-risk and T3 disease with extended lymph node dissection.
Haematuria
Refer for: visible haematuria at any age, or non-visible haematuria with risk factors.
Management: structured haematuria assessment with flexible cystoscopy and upper tract imaging where indicated.
Raised PSA, no diagnosis
Refer for: age-adjusted PSA elevation, rising PSA, or patient anxiety needing specialist review.
Management: clinical review and mpMRI, then targeted transperineal biopsy if indicated.
Upper tract urothelial cancer
Refer for: upper tract filling defect, ureteric tumour, suspicious upper tract cytology.
Management: robotic nephroureterectomy with lymph node dissection per EAU guidelines.
PUJ obstruction and ureteric stricture
Refer for: hydronephrosis, flank pain, MAG3 differential function under 35%.
Management: robotic pyeloplasty or ureteric reimplantation, psoas hitch for distal strictures, buccal mucosal graft ureteroplasty for proximal strictures.
BPH and LUTS
Refer for: failed medical therapy, bothersome symptoms, or patients wanting to discuss surgical options.
Management: Rezum, Aquablation, HoLEP, GreenLight and TURP, including ejaculation-preserving options.
General and benign urology
Refer for: scrotal conditions, vasectomy, incontinence, overactive bladder, recurrent UTI.
Management: full assessment and management, including surgical options.
Audited results
From Mr Sri's audited robotic series to the end of 2025, with definitions, so you can counsel patients before referral.
Trifecta, robotic partial nephrectomy
Negative margins, no major complications and warm ischaemia time under 25 minutes.
High complexity tumours
Of tumours treated with nephron-sparing surgery, RENAL nephrometry score above 10.
Positive margins
In robotic partial nephrectomy.
Continence at one year
Pad-free or minimal leakage after nerve-sparing RARP.
Open conversion
Across robotic prostatectomy, partial nephrectomy, nephroureterectomy and reconstruction.
Median length of stay
After robotic surgery. 900+ robotic cases as consultant, 225+ a year.
Individual outcomes vary. Full list of publications
Trials at St George's
Mr Sri is Principal Investigator at St George's for national randomised trials. Eligible NHS patients can be discussed for eligibility.
PARTIAL
Robotic partial versus radical nephrectomy for higher-risk renal tumours.
ELIPSE
RARP alone versus RARP with extended pelvic lymph node dissection in high-risk prostate cancer.
PART
Focal therapy versus standard radical treatment for localised prostate cancer.
What to include
More context means faster triage, and lets Mr Sri review the case before clinic.
Always include
- Patient name, date of birth and contact number
- Presenting complaint and history
- Relevant examination findings
- Current medications and allergies
- Insurance details or self-pay confirmation
- Preferred site: Wimbledon, Kingston, Marylebone or Harley Street
- Your contact details for the clinic letter
Include where available
- PSA values, current and historical
- MRI report and images (DICOM or image-sharing link)
- Previous biopsy histology
- Renal function and eGFR, for kidney cases
- Flow rate and bladder diary, for LUTS and BPH
- Previous operative notes
- MDT outcome, if discussed
