Direct intrauterine sampling with Uterobrush: cell preparation by the "flicked" method

Area of Science:

• Gynecologic Cytopathology
• Reproductive Medicine
• Oncologic Diagnostics

Background:

• Endometrial cytology is crucial for diagnosing endometrial lesions.
• Accurate sample collection and preparation are vital for cytological assessment.
• Previous work established cyto-architectural criteria for endometrial lesions.

Purpose of the Study:

• To evaluate the efficacy of the Uterobrush for endometrial sample collection.
• To demonstrate and improve cell preparation techniques for endometrial brushing specimens.
• To compare the Uterobrush with the Endocyte for endometrial cytology.

Main Methods:

• Compared three endometrial cell collection and preparation methods: conventional Uterobrush, "flicked" Uterobrush, and Endocyte.
• Investigated cell clump quantity and size distribution in prepared slides.
• Evaluated endometrial cytology in 90 women using these methods.

Main Results:

• The "flicked" Uterobrush method yielded a greater quantity of cell clumps compared to the Endocyte.
• Cell clump size distribution was similar between the "flicked" Uterobrush and Endocyte methods.
• Preparations from the "flicked" Uterobrush method were equivalent or superior for diagnosing endometrial lesions.

Conclusions:

• The "flicked" Uterobrush preparation method is effective for endometrial cytology.
• This technique aids in the diagnosis of endometrial lesions, with applicable criteria for both instruments.
• Findings support standardization of criteria for direct intrauterine cell samples.
