Operative Hysteroscopy: Choosing Resectoscopes, Energy and Pumps

Procedures and the equipment they need

Hysteroscopy polypectomy is the entry-level procedure: small polyps can be removed with scissors or a bipolar electrode through an office set, while larger or fibrous polyps are resected with a loop. Hysteroscopy myomectomy for submucosal fibroids needs more power, more working space and tight control of fluid absorption.

Septum division and removal of retained products of conception sit in between. Because the case mix drives the hardware, list the procedures and expected annual volumes before comparing quotations.

• Small polyps and biopsy: slim office set with 5 Fr instruments
• Larger polyps, septa: resectoscope with bipolar or monopolar electrodes
• Submucosal fibroids: resectoscope loop or mechanical tissue removal, with fluid-deficit monitoring
• Retained tissue: either approach, depending on the surgeon's preference

Resectoscopes versus mechanical tissue removal

A resectoscope uses an electrode loop to shave tissue in strips; the surgeon removes the chips and keeps the view clear. It is versatile, can also coagulate and is well established for operative hysteroscopy for fibroids. The Richard Wolf Princess is a slim 7 mm (21 Fr) example, usable with monopolar and bipolar current, with a rotating double sheath and continuous irrigation. See also our resectoscope overview.

Mechanical systems cut and aspirate tissue in one step, so chips do not need to be extracted repeatedly, and no electrical energy is applied to the cavity. In the common comparison of branded mechanical systems versus a resectoscope, neither wins universally: mechanical removal is often valued for polyps and soft fibroids and shorter learning curves, whereas a resectoscope handles dense and wide-based tissue and doubles as a coagulation tool. Many units keep both.

Energy: generator and electrode choice

A resectoscope needs an electrosurgical generator with a hysteroscopic program. The Richard Wolf HF-GENERATOR 2260 offers presets for monopolar and bipolar hysteroscopic resection with a maximum cutting power of 400 W and coagulation power of 350 W, and RFID detection of instruments for quick setup.

Bipolar current works in saline, which lowers the risk of hyponatraemia compared with monopolar current in a non-electrolyte solution. Check the electrode catalogue: loops, vaporisation electrodes and needle electrodes all behave differently, and the Princess accepts the BIVAP bipolar vaporisation electrode for endometrial ablation and myomas.

Fluid management and safety

Operative cases absorb fluid, so a pump with a fluid-deficit display is a safety device and not a luxury. The Richard Wolf FLUID CONTROL 2225 provides irrigation up to 1800 ml/min and suction up to 2000 ml/min, with continuous deficit monitoring through an optional balancing module with two weighing cells.

Define your alarm limits with the clinical team and train staff on the deficit procedure. For a deeper treatment of pressure, flow and setup see hysteroscopy fluid management.

Procurement checklist

Specify the camera tower, light source and monitor together with the operative set: see the 4K gynecology tower guide. Confirm sterilisation of each component, repair arrangements and training for surgeons and nurses.

Check current UAE device registration and facility licensing requirements with the relevant authority. Beckfinity can configure an operative hysteroscopy line for your department; contact our specialists for a quote or consultation.
