Hysteroscopy vs D&C: what each needs in the OR and sterile department

What a D&C set contains

A dilatation and curettage tray is a compact set of reusable instruments. It typically holds vaginal specula and retractors, a tenaculum, a uterine sound, a series of graduated cervical dilators, one or more curettes of different shapes, forceps for tissue handling, and bowls and swabs. It does not include an imaging chain.

The REDA range lists the relevant families: vaginal specula (Cusco, Pederson, Collin and Sims), Hegar uterine dilators, Recamier and other uterine curettes, uterine sounds, tenaculum and biopsy punch forceps, ovum forceps and aspiration curettes. See the REDA gynaecology instruments and our D&C instrument set guide for a typical tray layout.

What a hysteroscopy set adds

Hysteroscopy introduces an endoscopic imaging chain: a telescope, a sheath, a light source and cable, a camera and a monitor. It also needs a way to distend the cavity and keep the view clear, so a fluid-management pump becomes part of the set-up. Operative hysteroscopy adds a resectoscope or working instruments and an electrosurgical generator.

Richard Wolf's Princess is described as a slim 7 mm (21 Fr) continuous-flow resectoscope, expandable to 8 mm, with a hybrid design for monopolar and bipolar use and a rotating double sheath. Read the Princess resectoscope data sheet for the telescope and electrode details. The FLUID CONTROL 2225 pump covers gynecology, urology and general surgery with continuous fluid-deficit display.

• Imaging: telescope, camera, light source, monitor, recording.
• Fluid: pump or pressure bag, tubing sets, fluid-collection drapes and deficit monitoring.
• Energy: generator with hysteroscopic presets, electrodes, footswitch.
• Instruments: forceps, graspers, scissors and morcellation options as chosen.

Hysteroscopic D&C: what is a hysteroscopy D&C from an equipment view

A hysteroscopy-guided D&C combines both worlds. Clinicians inspect the cavity with a hysteroscope and then use curettes or other instruments, so the OR needs the hysteroscopy tower and the D&C tray in the same case. For hysteroscopic D&C equipment the practical point is workflow: the tray must be opened and counted, and the tower ready, without delaying turnover.

Some units use suction curettage with a dedicated vacuum unit. The ATMOS S 351 NATAL is described as a suction unit for obstetric vacuum extraction and suction curettage; see our note on the suction curettage unit. Whether any given technique is appropriate for a patient is a decision for the clinician.

Room setup: OR, day surgery or office

A D&C is traditionally set up in an operating or day-surgery room because it uses dilators and curettes with a patient under anaesthesia or sedation, according to local protocol. A hysteroscopy can run in the same room, or in an outpatient room if the facility has the imaging tower, the pump and a reprocessing route. Your licensing authority (DHA, DOH or MOHAP, depending on the emirate) defines what is permitted where, so confirm the current rules.

Both need a gynecological or operating table with leg supports, a procedure light, suction, power outlets for the tower and pump, and a clear route for specimens. For smaller rooms, see office hysteroscopy equipment.

Reprocessing, cost drivers and buying questions

A D&C tray uses plain instrument reprocessing: cleaning, inspection, packing and steam sterilization. Hysteroscopes, sheaths and resectoscopes are more delicate and need the manufacturer's validated cleaning and sterilization or disinfection method, and a stock plan so one scope failure does not stop the list. Capital cost sits mainly in the imaging chain and pump; per-case cost sits in tubing sets, fluid and electrodes.

Ask suppliers about registration, training, service coverage and spare parts, and request a total-cost view. Beckfinity's specialists can propose a configuration for your department; contact us through our contact page.
