Neither a passive recording nor a broadcast you cannot stop. Every mosaic™ capture is stepped through with the Remote, in the order the surgeon worked.
semilivesurgery.com is a surgical training platform that uses multi-screen recordings of real procedures, captured without editing, to train surgeons as close to reality as possible.
Our original capture technique, the mosaic recording™, combined with the semilive player, lets you relive a surgical procedure by choosing your camera angle at any moment, inside a Zoom conference room accessible 24/7 from anywhere in the world.
Learners choose the procedure they wish to revisit and take full control of the playback using the Remote. At their own pace. With their peers.
Additionally, one or more sessions with the surgeon who performed the procedure can be scheduled to go further and ask questions during a masterclass.
Mosaic Recording™
Our proprietary multi-screen capture method records every angle simultaneously, without editing, giving you the raw, unfiltered surgical reality.
Semilive Player
The semilive player restitutes surgery as if it were happening live. Full temporal control, free angle selection, at the pace of the learner.
The Remote
Via semilivecontrol.fr, learners take full command of the diffusion: pause, rewind, switch camera, drive the case. Broadcast into the shared Zoom room in real time.
Masterclass
A scheduled live session with the operating surgeon. Open Q&A, technique discussion, and in-depth review of the cases from the current programme.
WHY SEMILIVE
The closest thing to being there.
Three reasons why surgical teams choose semilivesurgery.com over traditional replay or live surgery sessions.
01
Closest to apprenticeship
This training method mirrors compagnonnage, the most established form of surgical teaching, placing the learner alongside the expert step by step.
02
No ethical constraints
Unlike live surgery sessions, there are no disruptions to the surgical environment, no ethical concerns about patient exposure, and no performance pressure for the operating surgeon.
03
Learner-controlled perspective
The freedom to choose your angle of view reproduces what more complex and expensive systems like VR offer, at a fraction of the complexity.
HOW IT WORKS
Five steps, full control.
From account creation to driving a live operative case, the platform is designed for surgeons, by surgeons.

CURRENT PROGRAMME
Mini-PCNL Percutaneous Nephrolithotomy
Steering committeeDr Nadia Abid
SpecialtyUrology
Cases available7
This programme focuses on minimally invasive percutaneous nephrolithotomy (mini-PCNL), a cornerstone procedure in urological stone disease management. Through 7 real operative cases performed by Dr Nadia Abid, learners explore patient selection, access strategy, lithotripsy choice, and immediate post-operative decision-making across a broad spectrum of complexity, from straightforward single stones to staged bilateral staghorn calculi in complex patients.
46-year-old woman admitted as emergency with obstructive pyelonephritis. Staghorn-like stone completely molding the lower calyx. Culture: Proteus mirabilis. Indication for mini-PCNL.
NADIA 02 · IMAGING
CASE 02AVAILABLE
Large renal pelvis stone, high CT density
Dr Nadia Abid
35-year-old male, left renal pelvis stone 26x22 mm, CT density ~1,600 HU. History of large stone at age 24. Emphasis on metabolic workup.
NADIA 03 · IMAGING
CASE 03AVAILABLE
Brushite recurrence, ulcerative colitis, 3 cm lower calyx
Dr Nadia Abid
54-year-old patient with ulcerative colitis and prior mini-PCNL in 2023 for 100% brushite stone. New recurrence, stone over 3 cm, CT densities 1500 to 1900 HU.
67-year-old female with tetraplegia since 1981, prior cystectomy with Bricker ileal conduit, paroxysmal AF on apixaban. Renal pelvis stone 25x30 mm. Highly complex anatomy.

CASE 06AVAILABLE
Massive staghorn over 5 cm, stage IIIB CKD, atrophic kidney
Dr Nadia Abid
75-year-old female, stage IIIB CKD, eGFR 30. Right staghorn over 5x4x5 cm. Trilogy lithotripsy, probe failures, switch to laser. Near-complete clearance achieved.
42-year-old male, renal transplant 19 years ago, eGFR over 90. Incidental graft calculus now 11 mm and mildly symptomatic. Retrograde catheterisation then percutaneous approach.

semilivesurgery.com is a surgical training platform using multi-screen recordings of real procedures (mosaic recording™) combined with the semilive player. Surgeons relive operations live, choose their camera angle, and discuss with peers inside a shared Zoom conference room, 24/7, from anywhere in the world.
A masterclass is a scheduled session with one or more expert surgeons, open for live discussion and questions about one or several operative cases proposed during the current training period.
The Remote is accessible via semilivecontrol.fr. Once inside the Zoom session, you take full control of the semilive player: pause, rewind, switch between camera angles, and drive the case at your own pace. All participants in the Zoom room see the same diffusion in real time.
semilivesurgery.com is designed for surgeons in training and practising surgeons who want to deepen their technical knowledge through immersive, realistic case review, without the ethical and logistical constraints of live surgery observation.
Standard surgical videos are edited, single-angle, and passive. The semilive player gives you full temporal control and free choice of camera angle across a multi-screen mosaic recording: the closest equivalent to standing in the operating room, at a fraction of the complexity of VR systems.
