Global Clinical Consultation Platform & Specialist Precedent Network

No complex case stays unprecedented simply because the right specialist is not here right now.

Clarivius connects treating physicians and patients facing complex, rare, or unresolved diagnoses with verified sub-specialists worldwide who have documented hands-on experience resolving that exact pathology—even when it sits outside all 24 European Reference Networks.

What Clarivius Is: A global clinical consultation platform and specialist precedent network offering two dedicated pathways: Clarivius Peer (rapid, zero-PII doctor-to-doctor consultations for physicians and hospitals) and Clarivius Direct (consent-backed specialist second opinions and full DICOM MRI/CT reviews for patients).

What Is Clarivius?

Clarivius is a Global Clinical Consultation Platform and Specialist Precedent Network. Unlike generic hospital directories or consumer symptom checkers, Clarivius combines an indexed global registry of verified specialist case histories with two purpose-built consultation workflows—one for treating physicians and hospitals, and one for patients.

01
The Core Intelligence Network

Global Specialist Precedent Index

Hospital directories list clinicians by broad department ("Urology" or "Surgery"), hiding who has actually solved a rare anomaly. Clarivius indexes verified sub-specialists worldwide by documented anatomical precedent—specific rare pathologies operated on, published surgical series, high-resolution MRI protocols, and peer endorsements.

02
For Physicians & Hospitals

Clarivius Peer (Doctor-to-Doctor Platform)

A zero-PII clinical consultation workflow for treating physicians, multidisciplinary tumor/radiology boards, and hospital departments. Submit a structured 4-field clinical case (Age, Sex, BMI, Clinical Narrative) in 90 seconds and receive a signed peer consultation summary from an international colleague who has treated that exact presentation.

03
For Patients & Families

Clarivius Direct (Patient-to-Specialist Service)

A dedicated, consent-backed specialist second-opinion and diagnostic review service for patients facing unresolved or complex conditions. Upload full DICOM imaging (3T MRI, CT) and clinical records in an isolated EU vault for deep sub-specialist review and three-way alignment with your local treating physician and hospital.

End-to-End Clinical Workflows

How Clarivius Works

Clarivius operates two strictly separated clinical pathways so hospital physicians can consult international peers rapidly with zero personal data, while patients can submit full identifiable imaging dossiers under explicit per-consultation GDPR consent.

Pathway A · Doctor-to-Doctor & Hospital Network

Clarivius Peer — Anonymised Physician-to-Specialist Consultation

1

Structured 4-Field Case Intake

The treating physician enters only four clinical parameters in under 90 seconds: Age, Sex, BMI, and a Free-Text Clinical Narrative detailing symptom triggers, negative imaging or lab results, prior procedures, and the specific diagnostic or surgical question.

2

Automated Zero-PII Privacy Shield

Before the case leaves the browser or enters the index, our Compliance Gate automatically scans and blocks any accidental personal identifiers (names, dates of birth, national ID numbers, hospital record numbers, phone numbers, or email addresses).

3

Precedent & Endorsement Matching

The Matching Engine ranks verified international sub-specialists by documented clinical similarity—matching specific anatomical structures, prior surgical series, high-field imaging protocols, and peer endorsements rather than generic department titles.

4

Collegial Exchange & Signed Summary

The matched specialist reviews the structured presentation and delivers a signed peer consultation summary outlining differential MRI sequences, anatomical pitfalls, and surgical options. Full clinical responsibility remains with the treating physician.

Pathway B · Patient-to-Specialist Direct Consultation

Clarivius Direct — Consented Dossier & Full DICOM Imaging Review

1

Consented Case & DICOM Intake

Under granular, per-consultation GDPR (Art. 6 & Art. 9) informed consent, the patient uploads their chronological medical history, lab reports, and full cross-sectional DICOM imaging (3T Pelvic MRI, CT, Ultrasound, endoscopy) into an isolated EU vault.

2

Sub-Specialist Precedent Selection

Rather than routing the patient to a general triage doctor, Clarivius matches the dossier to a verified international sub-specialist who has published on, diagnosed, or surgically resolved that exact anatomical or pathological condition.

3

Cross-Planar Imaging & Timeline Review

The matched sub-specialist inspects the raw multi-planar imaging sequences (such as T2-weighted and fat-suppressed STIR pelvic MRI) alongside physiological symptom triggers—identifying subtle ductal communications often missed in routine departmental reads.

4

Written Specialist Report & Shared Care

The patient receives a comprehensive written specialist consultation report plus a structured Treating-Physician Alignment Brief, aligning the international specialist, the patient, and their local hospital surgical team around a clear plan.

Founding Clinical Case Study · De-Identified 18-Month Journey

18 Doctors, 18 Months, and a Unilateral Cowper's Gland (Glandula Bulbourethralis) Anomaly

Clarivius was founded after an 18-month diagnostic odyssey across five medical specialties (General Surgery, Proctology, Urology, Radiology, and Microbiology). Here is the exact clinical progression showing why rare anatomical pathologies stall inside departmental silos—and how indexed specialist precedent resolves them.

Stage 1 (Months 1–2): Initial Perineal Mass, Furuncle/Neoplasm Misdiagnosis & First Pelvic MRI

General Surgery · Urology Ultrasound · 1st Pelvic MRI

An adult male presents with a painful, mobile 1.5 × 1.0 cm perineal lump near the left pubic bone without systemic fever (37.2 °C). Outpatient General Surgery initially diagnoses a cutaneous furuncle/abscess (ICD-10 L023) and prescribes topical ointment; 12 days later, when pain recurs specifically after ejaculation, Surgery re-classifies the lesion as an unspecified benign perineal neoplasm (ICD-10 D235). Urology performs scrotal and perineal ultrasonography: testes and epididymis are normal, but a 7 mm anechoic formation is identified near the anal sphincter, and perineal compression expresses slight discharge through the anal canal. The first Pelvic MRI (Month 2) reports a 47 mm transsphincteric perianal fistula opening at 1 o'clock with an external opening on the perineum posterior to the scrotum—missing the deeper urogenital glandular origin in the deep perineal pouch (spatium perinei profundum).

Clinical Blind Spot #1 (The Compartment Trap): Because the tract exited on the posterior perineum, triage defaulted to proctology ("cryptoglandular anal fistula") while overlooking the post-ejaculatory symptom trigger that pointed directly to an accessory urogenital gland.

Stage 2 (Months 3–7): Proctological Laser Closure (FiLaC) & High-Pressure Mucoprotein Relapse

Proctology · FiLaC Laser Ablation · Post-Operative Relapse

Acting on the MRI diagnosis of a transsphincteric perianal fistula, specialized Proctology performs surgical abscess extirpation and Fistula-tract Laser Closure (FiLaC) under analgosedation in Month 3. However, radial laser ablation only seals the distal posterior exit tract toward the anal triangle while leaving the upstream secretory source in the urogenital diaphragm untouched. By Month 7, the fistula relapses with intermittent clear-to-white mucoprotein discharge. Proctology can no longer differentiate an internal rectal opening and recommends conservative management with anal dilators and topical ointment.

Pathophysiological Mechanism: During sexual emission and bulbospongiosus contraction, periurethral and bulbourethral intraductal pressures reach 200–500 cm H2O. Sealing the distal skin exit without decompressing or excising the ruptured bulbourethral duct guarantees that pressurized glycoprotein secretions will re-dissect the perineal tissue planes.

Stage 3 (Months 8–11): The Multi-Departmental Diagnostic Deadlock (UCG, CT & Anoscopy All Negative)

Emergency Surgery · Retrograde Urethrography (UCG) · Pelvic CT · Anoscopy

By Month 10, the physiological trigger is unmistakable: clear viscous fluid discharges from the perineal opening specifically during sexual arousal and post-ejaculation. Proctology suspects a urinary tract communication and refers the patient to University Hospital Urology, yet every standard departmental test comes back negative or inconclusive: (1) Emergency Surgery incision under local anaesthesia extracts less than 1 ml of fluid; (2) University Hospital Retrograde Urethrography (UCG, Month 10) demonstrates a completely normal, smooth urethra and bladder with zero contrast extravasation, leading Urology to conclude: "The urological picture does not explain the presence of the perianal fistula"; (3) Abdominal & Pelvic CT (Month 11) shows no fluid collection, labeling the lesion a "minimal postoperative fibrous scar"; and (4) University Hospital Surgical Anoscopy (Month 12) probes a blind 15 mm external tract at 6 o'clock and advises "conservative observation."

Clinical Blind Spot #2 (Why UCG & CT Were False-Negative): Positive retrograde contrast pressure inside the urethral lumen compresses the oblique 2 cm Cowper's duct orifice shut like a one-way valve, preventing retrograde filling on fluoroscopy. Meanwhile, standard CT lacks the soft-tissue contrast resolution to visualize a pea-sized (5 mm) mucin gland inside the muscular urogenital diaphragm.

Stage 4 (Months 11–12): Patient-Led 3T T2 Pelvic MRI Breakthrough & Bulbourethral Proof

3T T2-Weighted Pelvic MRI · Flexible Cystoscopy · Differential Microbiology

Trapped in a referral loop where Proctology states "not rectal" and Urology states "normal urethrogram," the patient personally cross-references repeat high-resolution 3T T2-weighted pelvic MRI sequences against topographical atlases of the male urogenital diaphragm. Comparative T2 MRI analysis reveals the exact anatomical source: the perineal fistula tract communicates directly with the right bulbourethral (Cowper's) gland (glandula bulbourethralis)—a ruptured bulbourethral syringocele/ductal pathology tracking along Colles' fascia and the perineal body. Subsequent flexible urethrocystoscopy (Month 12) confirms focal mucosal hyperemia in the bulbar urethra, and differential cultures isolate ESBL-producing Escherichia coli in the fistula tract versus Enterococcus faecalis in prostatic/ejaculate secretions, proving a chronic bulbourethral-perineal communication with secondary colonization.

Diagnostic Gold Standard: High-resolution multi-planar 3T T2-weighted and fat-suppressed STIR pelvic MRI visualizes mucin-filled bulbourethral glands and ducts as hyperintense structures without requiring retrograde cannulation, complemented by biochemical fluid analysis (PSA/amylase vs. creatinine).

Stage 5 (Months 13–18): Multidisciplinary Reconstructive Indication & The Clarivius Counterfactual

Reconstructive Urology Board · European Specialist Precedent Network

After gland rupture into the rectum causes acute purulent drainage and subfebrile temperatures, a joint radiological and reconstructive urology committee finally indicates definitive surgical extirpation of the fistula tract and right Cowper's gland with urethral reconstruction under targeted intramuscular gentamicin coverage. Why Clarivius Was Built: While Cowper's gland syringoceles and fistulas fall outside all 24 official European Reference Networks (ERNs), dedicated European reconstructive urology teams—at UCLH London (Bugeja & Mundy, who documented Cowper's duct anomalies in 33% of urethrograms), University of Perugia, Amsterdam UMC / UMC Utrecht, University Hospital Albacete, and UMC Ljubljana—have published extensive clinical series on transurethral Holmium:YAG laser marsupialization (deroofing) and transperineal bulbourethral excision.

The Clarivius Impact: By indexing sub-specialists by actual anatomical and surgical precedent (`glandula bulbourethralis`, adult syringocele, post-FiLaC perineal fistula), Clarivius connects the treating doctor or patient with the right reconstructive team in days—compressing an 18-month diagnostic odyssey into a single targeted consultation.

Our mission: "No complex case stays unprecedented simply because the right specialist is not here right now."

Our Founding Story

Why We Built Clarivius After an 18-Doctor Diagnostic Odyssey

Clarivius was born from direct personal experience: watching a treatable anatomical pathology of the right bulbourethral gland (glandula bulbourethralis) bounce across 18 doctors and 5 specialties for 18 months—enduring misdiagnoses, a failed proctological laser surgery (FiLaC), and false-negative fluoroscopy and CT scans—until high-resolution 3T pelvic MRI analysis finally revealed the deep urogenital origin.

The medical knowledge to diagnose and resolve that exact anomaly was not missing from the world; it was already published by reconstructive urology teams in London, Perugia, Utrecht, Albacete, and Ljubljana. What was missing was the clinical routing infrastructure to connect local treating doctors and patients to documented sub-specialist precedent across borders.

Global Network · European Operations

Global-First Precedent Network with European Clinical Governance

Clarivius is designed global-first—indexing verified sub-specialist precedent across Europe, North America, and leading academic medical centers worldwide—with initial European clinical operations anchored in Prague, Czechia.

Every consultation runs on strict European Union data residency (Frankfurt / Prague), enforcing cryptographic and database separation between anonymised peer consultations (Clarivius Peer) and consent-backed patient dossiers (Clarivius Direct).

1. Precedent Over Prestige

Specialists are matched strictly by documented rare-case history, surgical series, and peer endorsements—never by paid placement or advertising.

2. Privacy by Architecture

Zero-PII peer consultations and consent-backed patient dossiers operate on physically separate schemas, encryption keys, and access roles.

3. Human Clinical Authority

Software structures cases and indexes precedent; only verified, licensed human sub-specialists author clinical consultation opinions.

4. Shared Care Alignment

Every consultation is structured to support and empower the patient's local treating physician and hospital surgical team.

Clinical, Platform & Governance FAQ

Frequently Asked Questions

Clear answers on how Clarivius operates for treating physicians, hospital directors, sub-specialists, and patients facing complex or rare conditions.

What is Clarivius — is it a product, a platform, or a medical service?

Clarivius is a Global Clinical Consultation Platform and Specialist Precedent Network. It combines a searchable Global Specialist Precedent Index with two dedicated clinical pathways: Clarivius Peer (a zero-PII doctor-to-doctor consultation platform for treating physicians and hospitals) and Clarivius Direct (a consent-backed patient-to-specialist consultation and DICOM imaging review service).

How does Clarivius Peer work for treating physicians and hospital departments?

In Clarivius Peer, a treating physician submits a structured 4-field clinical case (Age, Sex, BMI, and de-identified Clinical Narrative) in under 90 seconds. Automated privacy filters verify that zero personal identifiers are present, the Precedent Engine ranks verified global sub-specialists by documented clinical experience with that exact pathology, and the matched specialist returns a signed peer consultation summary while clinical responsibility stays 100% with the treating doctor.

How does Clarivius Direct work for patients seeking a specialist review?

In Clarivius Direct, patients submit their chronological medical history, lab results, and full multi-planar DICOM imaging (such as 3T Pelvic MRI or CT scans) under explicit per-consultation GDPR informed consent inside an isolated EU vault. Clarivius matches the dossier to a verified international sub-specialist who inspects the raw imaging sequences and delivers a comprehensive written specialist opinion plus a Treating-Physician Handover Brief for shared care with the patient's local hospital.

Why do retrograde urethrography (UCG) and CT scans often miss Cowper's gland (glandula bulbourethralis) fistulas?

During retrograde urethrography (UCG), positive intraluminal contrast pressure inside the bulbar urethra frequently compresses the oblique bulbourethral duct orifice shut like a one-way flap valve, preventing contrast from entering the Cowper's gland duct and yielding a false-negative read. High-resolution 3T T2-weighted and fat-suppressed STIR pelvic MRI visualizes the mucin-filled bulbourethral gland and its fistulous tracks directly within the deep perineal pouch without requiring retrograde cannulation.

How does Clarivius protect patient data under GDPR and EU healthcare regulations?

Clarivius enforces hard architectural separation between its two tracks. Clarivius Peer processes only four non-identifiable parameters (Age, Sex, BMI, Clinical Narrative) with automated PII blocking. Clarivius Direct processes identifiable records and DICOM imaging in a completely separate database schema, encryption key hierarchy, and role boundary hosted in the European Union under explicit GDPR Art. 6 and Art. 9 consent.

Does Clarivius use AI to diagnose patients or replace my treating doctor?

No. Software and AI components on Clarivius are strictly restricted to case structuring, personal-identifier blocking, and specialist precedent indexing. They never generate medical diagnoses or treatment recommendations. Every clinical consultation is authored by a verified human sub-specialist and is designed to support the patient's local treating physician.

Clarivius Direct · Patient-to-Specialist Consultation & Shared Care

Direct Specialist Case & Imaging Review for Complex or Unresolved Conditions

When your case remains unresolved after multiple consultations, Clarivius gives you two immediate ways forward: invite your treating physician to consult a matched international peer via Clarivius Peer, or initiate a consent-backed specialist dossier & DICOM imaging review via Clarivius Direct.
