Plasma EDGE by Lamidey Noury is a bipolar plasma resection system for urological surgery. Its components include an electrosurgical unit, working element, resectoscope and a range of electrodes. The system supports applications in BPH/prostate resection, bladder tumor resection and enucleation using PlasmaLEP™. Configuration selection depends on the procedure, instrument size and component compatibility. [1,2]
What components make up the system?
Evaluating a resection system involves more than the generator alone. The Plasma EDGE system comprises a bipolar electrosurgical unit, compatible working element, 26 Fr and 22 Fr sheaths, and electrodes for different tasks. [1 pp. 3, 7–9]
Before assembling a set, verify the generator, working element, inner and outer sheaths, obturator, optic and electrode against product codes and the manufacturer's compatibility information.
Bipolar design and plasma activation
The “Real Bipolar” design integrates both polarities and the current pathway within the electrode, with a directly attached cable. Return current passes through the electrode assembly rather than the resectoscope or sheath. [1 pp. 4–5, 9]
The system supports plasma activation without tissue contact or pre-warmed saline, together with high dynamic coagulation. [1 p. 4; 3] These are equipment design characteristics. Energy settings, irrigation fluid and accessories must follow the instructions for the actual configuration used.
Considerations for bipolar TURP in BPH
For benign prostatic hyperplasia (BPH), the system supports cutting and coagulation with a range of electrodes for prostate resection. [1 pp. 9–10]
- Loop electrodes: Thin and thick loops are available for consideration within the relevant instrument configuration.
- Vaporization electrode: A further option in the system's electrode range.
- Ball electrode: Included for coagulation applications specified by the manufacturer.
Check electrode code, shape, size and compatibility with the working element and sheath. This article does not prescribe energy settings or replace operating instructions and training.
Considerations for TURBT and bladder tumor resection
For transurethral resection of bladder tumor (TURBT), contact-free plasma activation and the plasma corona design support controlled cutting and biopsy sampling. [1 p. 10]
The range includes a straight bladder loop and other loop designs. Lesion location, endoscopic access and electrode details should be considered together with the system's requirements. [1 p. 9]
The system includes HF power shutdown when an electrode fault is detected. [1 p. 10; 3] Intraoperative risk assessment and anesthesia planning remain matters for the treating team, based on the patient and institutional practice.
22 Fr and 26 Fr resectoscopes: check the complete set
Resectoscopes are available in 26 Fr and 22 Fr sizes, with the 22 Fr option for situations where a smaller instrument is desired. The 22 Fr set includes a 22/19 Fr double-flow sheath, specific working element, electrode and a 2.9 mm, 30° optic. [1 pp. 7–8]
Verify the 22 Fr set separately from the 26 Fr configuration, particularly its optic, working element and electrode. A smaller-size option is a design feature rather than evidence of a clinical benefit for every patient.
Can existing optics and sheaths be retained?
Working element options accommodate compatible optics and sheaths. Depending on the configuration, replacing the working element may permit use without replacing the complete resectoscope. [1 p. 6]
Provide the brand, model and product codes of the optic, its size and viewing angle, the inner and outer sheaths, and the working element currently in use. This enables a configuration-specific compatibility review.
PlasmaLEP™ for bipolar enucleation
PlasmaLEP is an enucleation electrode combining a mechanically pushed wire structure with targeted energy delivery to assist adenoma separation, cutting and coagulation during dissection. [1 p. 11; 4]
Insulation on both sides of the wire is part of its design for energy delivery at the working area. Assess instrument compatibility and the surgical team's training requirements for bipolar enucleation when considering a PlasmaLEP configuration.
Information checklist for urologists and instrument teams
- Identify the procedures of interest: TURP, TURBT or bipolar enucleation.
- Provide the brand, model and product codes of existing resectoscopes, optics and sheaths.
- Specify the sizes being considered, such as 22 Fr or 26 Fr.
- Request the electrode and accessory list, with use and post-use handling information for each item.
- Request product instructions, compatibility information and details of available training or demonstrations.
- Discuss procurement, service terms and quotations for the organization's intended scope.
Request Plasma EDGE information
Urologists and instrument teams considering bipolar resection can contact Tawanmcweis to request configuration, electrode and compatibility information and manufacturer documentation.

คำถามที่พบบ่อย / FAQ
Which urological applications does Plasma EDGE cover?
Plasma EDGE supports BPH/prostate resection, bladder tumor resection and bipolar enucleation with PlasmaLEP. Configuration must match the procedure and product instructions.
Must saline be warmed for plasma activation?
Plasma EDGE does not require warmed saline for plasma activation. Prepare and use irrigation fluid according to the instructions for the actual configuration.
Are all 22 Fr and 26 Fr components interchangeable?
Compatibility must be checked by configuration. The illustrated 22 Fr set uses a specific working element and a 2.9 mm/30° optic; verify optic, sheath and electrode codes before combining components.
Can existing optics and sheaths be used?
This may be possible in manufacturer-confirmed compatible configurations. Provide existing models and product codes for review rather than assuming universal compatibility.
Is PlasmaLEP a laser enucleation system?
PlasmaLEP is a bipolar enucleation solution combining mechanical adenoma separation with energy for cutting and coagulation.
What information is needed for configuration advice and a quotation?
Provide the intended procedures, existing generator and resectoscope models, optic/sheath sizes and codes, and required electrodes to coordinate components, compatibility, documentation and service scope.
