Nutcracker Syndrome. Flank pain, hematuria, and what sets it off.
NCS comes with left flank pain and blood in the urine that often track with standing and walking. Leo's NCS hub is a focused dashboard over your symptom logs — it counts hematuria episodes and positional triggers, alongside relevant kidney labs.
A curated view over what you already log.
There's no separate NCS data-entry app. You log symptoms — and tag triggers like standing or walking — and the hub reads them back: hematuria episodes and how often standing/walking triggers showed up over the last 30 days.
An optional duration tracker counts the days since onset, and a feedback banner lets you ask for anything the hub is missing.
The signals that matter for NCS.
Hematuria episodes
How often blood in the urine shows up over the last 30 days.
Standing / walking triggers
Symptom logs tagged with standing or walking, counted — the positional pattern NCS is known for.
Symptoms & flares
A 7-symptom NCS set plus flare logging — left flank pain, foamy urine, pelvic heaviness, lightheadedness.
Labs
CBC, CMP, kidney and iron come pinned, with trends and reference ranges.
What ships in the Nutcracker Syndrome hub.
Leo tracks. It doesn't diagnose.
NCS is diagnosed by a clinician with imaging and urine studies — Leo has no screener and makes no claim about whether you have it.
This hub is a focused dashboard over your own logs and labs. Everything is descriptive and on-device-first; the counts describe what you recorded, never predict or advise.
Flank pain and hematuria, on the record.
A focused dashboard that surfaces hematuria episodes and positional triggers from your symptom logs, with the kidney labs an NCS work-up runs — organized for your specialist.
