Comparison of probe sheaths for endovaginal sonography

Area of Science:

• Medical imaging
• Ultrasound technology
• Infection control

Background:

• Endovaginal ultrasound examinations require sterile probe coverage to prevent contamination.
• Commercially available probe covers are standard but may have limitations in integrity.
• Alternative, cost-effective probe coverings warrant investigation for clinical use.

Purpose of the Study:

• To evaluate the effectiveness of condoms as a substitute for commercial probe covers.
• To compare the breakage and contamination rates between condoms and standard probe covers.

Main Methods:

• A 10-month prospective study involving endovaginal ultrasound examinations.
• Randomized use of either commercial probe covers or condoms on the vaginal probe.
• Post-use assessment of sheaths for leakage (breakage rate) and probe contamination.

Main Results:

• Condoms demonstrated a significantly lower perforation rate (1.7%) compared to probe covers (8.3%).
• Probe contamination occurred less frequently with condoms (1/178) than with probe covers (9/174).
• The relative risk of breakage and contamination was substantially higher for probe covers.

Conclusions:

• Condoms are a superior and more economical option for covering ultrasound probes during endovaginal examinations.
• The use of condoms significantly reduces the risk of probe damage and potential patient contamination.
