Pre-operative ultrasonographic evaluation of nongravid, enlarged uteri--correlation with bimanual examination
1Department of Obstetrics and Gynecology, Rabin Medical Center, Petah Tikva, Israel.
Objective:
To correlate the size of the nongravid uterus measured by ultrasound and bimanual examination before hysterectomy, with the actual size of the specimens.
Patients And Methods:
Uterine size of 49 consecutive patients, who underwent elective hysterectomy, was assessed by bimanual pelvic examination, preoperative ultrasonographic evaluation and actual postoperative size.
Results:
All preoperative ultrasonographic uterine dimensions significantly correlated with the corresponding actual dimensions of the uterine specimens. Furthermore, ultrasonographic uterine length had the best correlation with uterine size estimation by bimanual examination. A formula was established in an attempt to calculate clinical uterine size by gestational week, using preoperative ultrasonographic dimensions.
Conclusions:
By using the aforementioned formula, ultrasonographic uterine dimensions can be extrapolated to uterine size in terms of gestational week, and therefore, be applicable to traditional clinical practice.

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.

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...
