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).
"Recurrent perineal fistula post-FiLaC laser closure with clear mucoprotein discharge triggered by sexual arousal. Retrograde urethrography (UCG) and pelvic CT negative; 3T T2-weighted pelvic MRI identifies communication with the right Cowper's gland (glandula bulbourethralis) in the deep perineal pouch."

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.
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.
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.
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.
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.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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).
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.
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."
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.
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.

Our mission: "No complex case stays unprecedented simply because the right specialist is not here right now."
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.
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).
Specialists are matched strictly by documented rare-case history, surgical series, and peer endorsements—never by paid placement or advertising.
Zero-PII peer consultations and consent-backed patient dossiers operate on physically separate schemas, encryption keys, and access roles.
Software structures cases and indexes precedent; only verified, licensed human sub-specialists author clinical consultation opinions.
Every consultation is structured to support and empower the patient's local treating physician and hospital surgical team.

Clear answers on how Clarivius operates for treating physicians, hospital directors, sub-specialists, and patients facing complex or rare conditions.
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).
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.
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.
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.
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.
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.
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.
Many hospital specialists welcome international sub-specialist input when it takes less than 90 seconds and requires zero patient paperwork. Print or save our 1-page Treating-Physician Brief to hand to your urologist, surgeon, or radiologist at your next appointment.
