Objectives:
To provide reference values for ovarian volume in healthy premenarchal girls for use in routine pelvic ultrasonography interpretation.
Material And Methods:
A retrospective analysis of 170 healthy girls aged 0 to 11 years who underwent pelvic ultrasound examinations between 2015 and 2022 at a private gynecology clinic. Ovarian volumes were measured using transabdominal ultrasonography and calculated by the prolate ellipsoid formula. Mean ovarian volumes were analyzed by age groups.
Results:
The mean ovarian volume increased with age. A significant difference between right and left ovarian volume was not observed in most age groups. The data provides age-specific reference values that may aid in the clinical evaluation of ovarian development in premenarchal girls.
Conclusions:
Our study confirmed that significant variations in ovarian volume occur across various stages of growth and puberty, making the accurate determination of abnormal values essential for proper diagnosis.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
