About

It started as a personal
tool.

UroRef has 700+ combined App Store and Google Play downloads as of August 2026. It has grown into a five-project learning ecosystem — built on a urology on-call, for urology trainees, by someone who kept running out of time to look things up.

02 Who built it

Clinician by training,
builder by instinct.

I'm Nity - a urology SpR in the North West of England, and the person who writes and builds UroRef.

I trained in medicine at King's College London and took my MRCS with the Royal College of Physicians and Surgeons of Glasgow. Since then it has been the ordinary, unglamorous work of surgical training: clinics, lists, nights, on-calls, and the hundreds of small decisions that sit between them.

The other half of the story starts much earlier, and much further east. I grew up in Singapore, and my first websites were built in primary school with Microsoft FrontPage and basic Dreamweaver. That was as far as coding went for a long time. In between came the Singapore Youth Flying Club, two years of National Service in the army, and then medicine, which left little room for anything else. I only learned to code properly much later in life, teaching myself JavaScript and React in the gaps around hospital rota - and for a while the two lives ran quietly in parallel.

They collided on a urology on-call. The gap I kept hitting was never that the knowledge did not exist; it was that I could not reach it fast enough. So I built the thing I wanted in my pocket. That became UroRef, and UroRef became a family of tools - source-led reference, spatial anatomy and deliberate teaching rehearsal.

These days I build in the open with the people who use it: trainees, trainers, and the BAUS Digital Innovation Group committee, where a lot of these conversations now happen.

- The path so far
  1. Primary schoolFirst websites, in Singapore

    Microsoft FrontPage and basic Dreamweaver. Drag, drop, publish.

  2. Growing upSingapore Youth Flying Club

    A member of the club. Where the aviation further down this page began.

  3. After schoolTwo years in the army

    National Service. Two years in uniform before the next chapter.

  4. Medical schoolMBBS, King's College London

    Medicine took the foreground. The childhood websites were forgotten.

  5. SHO yearsUrology on-call

    Coude tips, on-call fog, and the private notes that would later become UroRef.

  6. MembershipMRCS, RCPS Glasgow

    The exams done, the surgical path committed to.

  7. RegistrarUrology SpR, North West

    Theatre lists by day, and a growing family of tools around them.

  8. NowFive connected public projects

    A source-led learning hub spanning quick reference, spatial teaching and operative rehearsal. UroRef has 700+ combined App Store and Google Play downloads as of August 2026; see the evidence and limitations above.

03 Why I built it

Built by a similarly troubled soul.

UroRef was not built by someone pretending medicine is simple. It was built by someone who remembers exactly what it feels like when your brain goes blank at the wrong moment.

As an SHO on urology on call, the things that caught me out were rarely glamorous. I still remember quietly wondering what on earth people meant by a coude tip catheter. It was the practical details that got you, the ones everyone mentions so casually, as if you were simply expected to know them already.

And that is really the point. On call, the problem is rarely that the information does not exist. Your brain is busy juggling referrals, bleeps, ward problems, sick patients and the constant low-level worry that you might be missing something. On-call fog is real. Nobody is calmly thinking "let me search for that stone probability calculator I once heard about on a ward round". You need the answer quickly, safely and with as little friction as possible.

I came to believe that the number of button clicks matters more than people realise. A resource is not useful only because its content is correct. It is useful because you can reach it quickly, clearly and with minimal effort when you actually need it. In pressured environments, convenience is not a luxury. It is part of safety.

So, with some background in JavaScript and React, I built a small tool for myself. Feedback from trainees and trainers slowly shaped it into something more polished, and one tool has since become a family of them.

If it makes even one on-call shift a little easier, it has done its job.

The UroRef ecosystem of clinical tools
The ecosystem, so far
To all the FYs and CTs: I can assure you, UroRef was built by a similarly troubled soul.
01 Build it on the ward, not in a boardroom.

Every tool here started as a problem I had in front of a patient, and gets used on a real shift long before I call it finished.

02 Measure it, or it did not happen.

Every reported result should state what was measured and keep its source, denominator, dates, method and limitations visible. Usability and self-rated confidence are not clinical outcomes.

03 Stay firmly in scope.

None of this replaces clinical judgement, local guidance, senior advice or formal protocol. Knowing where a tool stops is part of designing it.

04 The projects · five scenes

One clinical problem.
One focused tool. Repeated.

Everything below started as a real friction point in training, on-call work or NHS quality improvement. Nothing here replaces judgement or local guidance. It just makes the useful thing easier to reach.

Scene 01 / Clinical referenceLive

UroRef

Quicker orientation. Sources within reach.

An offline-core educational companion for the first difficult minutes of common urology problems: quick-reference pathways, checklists, operative-note prompts, calculators, doses, escalation prompts and routes to original resources. In early feedback from a three-site quality-improvement evaluation, participating trainees' mean self-rated confidence increased from 3.1 to 4.4 out of 5 after using UroRef. This preliminary, self-reported measure did not assess clinical competence, patient safety or patient outcomes. Ask Ariadne · An optional online AI feature.

- Beyond the ward

Off duty, still curious.

The projects get the headlines, but most of them were born from the same restlessness that fills the rest of my time.

Chess

Around 1000 Elo and climbing, one Chessable course at a time. The endgame study is going better than the blitz record.

Geopolitics & strategy

Maps, supply chains and long games. The night-shift reading that has nothing to do with urology, mostly.

Tabla

Rhythm practice in the gaps between shifts.

Aviation

From the Singapore Youth Flying Club to an enthusiast with a private pilot's licence gathering dust somewhere. One day.

05 Governance

Where this tool stops.

UroRef is an independent quick-reference tool for healthcare professionals. It is not a substitute for clinical judgement, senior advice, or local protocols.

Clinical content cites relevant sources, including EAU, NICE and BAUS guidance. Review of guideline-dependent content against the 2026 EAU Guidelines is in progress. Until a section's review is complete, verify it against the current source guidance and your local protocols.

Where recorded, source, date, jurisdiction and review status are shown; the original current source remains authoritative.

Content is authored by Nity G, Urology SpR. UroRef is not affiliated with or endorsed by EAU, NICE or BAUS.
