The frequency of gallbladder stones among patients who were sent for abdominal ultrasound at Mogadishu Somali Turkey Training and Research Hospital, Mogadishu, Somalia, during the period between January 2018 and June 2022 was assessed in this study. Methods: This is a record-based study that was carried out at the radiology department of Mogadishu Somali Turkey Training and Research Hospital on patients who were chosen for abdominal ultrasounds during the months of January 2018 and January 2022. The study focused on cases that occurred within those periods. Reports of abdominal ultrasounds served as the source of the collected data. Results: Records from 2352 patients are included in this study. They were divided into 451 (19.1%) males and 1901 (80.8%) females. Patients with GBS were present in 76.4 percent of cases. 73.2 percent of patients had big stones larger than 5 mm, while 53.4 percent of patients had several stones. GBS 1474 (77.5%) was substantially more common in females than in males (71.6%: 323/451) (P 0.008). The presence of small stones (less than 5 mm) was also shown to be significantly different between males and females (P = 0.015). Furthermore, compared with men, females had a considerably higher frequency of big GBS (5 mm) (P 0.015). Conclusion: In this study, it was discovered that females were significantly more likely than males to have GBS. Small stones were found much more frequently in the males. When compared to men, females had a considerably higher frequency of large GBS.展开更多
