Objective: To evaluate the accuracy of ultrasonography (US) in measuring the urinary tract stone using non-contrast computed tomography (NCCT) as the standard reference. Patients and methods: A total of 184 patients suspected with urolithiasis who had undergone NCCT and US radiologic investigation from 2015 to 2017 were enrolled in this study. The sensitivity, specificity, and stone size measured in US were validated by NCCT. Data of the stone size in US were classified into four groups (0–3.5, 3.6–5, 5.1–10, >10 mm) and then compared with NCCT data. Results: In 184 patients, NCCT detected 276 (97.2%) stones, while US could identify 213 (75.5%) stones. Overall sensitivity and specificity of US were 75.4% and 16.7%, respectively. Detection rate of mid and distal ureteral stone was lower than that at other locations. The detection rate increased with the stone size. About 73% concordance was obtained for the stone size measured by US and NCCT (Pearson’s correlation coefficient was 0.841). Factors such as the stone size, amount of hydronephrosis, and weight affected the detection rate of the urinary tract stone using US (P<0.001, P=0.02, and P=0.01, respectively). Conclusion: The stone size obtained by US was almost the same as that detected by NCCT; however, US is a limited imaging modality in detecting urinary tract stone, especially when used by an inexperienced radiologist, and in the case of smaller stone size, increased weight, and low grade of hydronephrosis.

Background: Miniaturization of endoscopic instruments in percutaneous nephrolithotomy (PCNL) allowed less invasive procedures with low complication rates, especially in children. This study was conducted to evaluate the safety and efficacy of ultrasonography-guided (USG) versus fluoroscopy-guided (FG) mini-PCNL in children.Materials and methods: This is a retrospective comparative study conducted from June 2015 to June 2020. The sample included 70 children (35 pateints underwent USG mini-PCNL and 35 pateints underwent FG mini-PCNL). They were compared mainly by the patients’ demographic characteristics, procedural information, and post-treatment outcomes. In the USG mini-PCNL group, puncturing was performed using a 3.5 MHz US probe, whereas fluoroscopy was utilized in the FG mini- PCNL group. Results: Both groups were comparable in terms of gender, previous history of failed ESWL, and hydronephrosis grade. The mean stone burden was 15.94 ± 3.69 mm and 19.20 ± 7.41 mm in USG and FG groups, respectively (p = 0.024). The stonefree rate (SFR) was 97.1% in the USG group and 94.3% in the FG group, which was not statistically significant (p = 0.16). Mean operative time in the USG group and FG group was 69.00 ± 13.33 minutes and 63.48 ± 16.90 minutes, respectively. Four (11.4%) patients in the FG group required blood transfusions to restore the hemodynamic state (p = 0.039). Fever was detected in 4 (11.4%) patients in the USG group and 15 (31.4%) patients in the FG group (p = 0.041). Conclusions: In children, mini PCNL under USG is safe and as effective as fluoroscopy.

Background: Limited evidence is available regarding the management of small bowel obstruction in the virgin abdomen (SBO-VA), with most studies excluding this entity. This study aims to assess the available data on the treatment outcomes and predictors of surgical intervention in SBO-VA. Methods: A retrospective cross-sectional study was conducted between 2015 and 2021, including all diagnosed and managed cases of SBO-VA at Al-Nasar Hospital. Patients were divided according to the treatment approach into surgical or conservative groups. Preoperative laboratory and radiologic data were gathered and compared between groups. Results: During the study period, 67 cases, primarily males (58.2%), with an average age of 52.2± 14.4 years were assessed. Common comorbidities included diabetes (20.9%) and hypertension (16.4%). Key symptoms were rebound tenderness (82.1%) and abdominal tenderness (70.1%). The predominant etiology was adhesions (23.9%). About 46.2% received conservative treatment, 53.8% underwent urgent surgery. Conservative treatment failed in 9.4% of cases, and complications arose in 23.9%, with most being fever (17.9%). Factors necessitating surgical management included older age (58.8 ± 11.7 vs 44.9 ± 13.8 years, p< 0.001), previous hospital admission (p< 0.001), presence of abdominal tenderness (p=0.030), longer abdominal pain duration (4.0 ± 0.9 vs 2.1 ± 0.6 days, p< 0.001), higher C- reactive protein (p= 0.033), higher white blood cell (p= 0.006), longer time to hospital presentation (75.3 ± 17.2 vs 39.0 ± 22.8 days, p= < 0.001), small bowel thickness ≥ 3 cm (p=0.009), and reduced bowel enhancement (p < 0.001) on computed tomography imaging. In surgical group, the need for ICU admission was higher and hospital stays were shorter than in conservative group and were statistically significant (p< 0.05). Conclusion: The main etiology of SBO-VA in our study was adhesions. Older age, previous hospital admission, longer abdominal pain duration, abdominal tenderness, increased inflammatory markers, and alarm signs on CT scans are the main factors for determining the need for urgent surgical exploration in patients with SBO-VA. To achieve prompt identification and intervention, it is crucial to maintain a high level of vigilance and awareness, even in individuals with no prior surgical history. Plain Language Summary: here is limited evidence available regarding the management of small bowel obstruction in the virgin abdomen (SBO-VA), with most studies excluding this entity especially in resource-limited settings. In this study, we investigated the factors associated with the need for surgical interventions in 67 cases diagnosed with SBO-VA. Our result showed that the predominant etiology was adhesion. While 46.2% received conservative treatment, 53.8% underwent urgent surgery. Conservative treatment failed in 9.4% of cases. Factors associated with need for surgical management included older age, previous hospital admission, presence of abdominal tenderness, longer abdominal pain duration, higher C-reactive protein (CRP), higher white blood cell (WBC), longer time to hospital presentation, small bowel thickness ≥ 3 cm and reduced bowel enhancement on computed tomography imaging. In surgical group, the need for ICU admission was higher and hospital stays were shorter than in conservative group.

Pentalogy of Cantrell is a congenital anomaly of the median mesodermal constructions with a poor prognosis. It is characterized by defects of the anterior diaphragm, the lower sternum, the abdominal wall, pericardium, and various congenital heart malformations. We present a case of ectopia cordis and Pentalogy of Cantrell in a newborn of a healthy 35-year-old woman with no history of embryotoxic exposure or smoking. The infant was first diagnosed with the anomaly in the second trimester of pregnancy and was delivered at 35 weeks of gestational age via a caesarian section. Shortly after birth, he was transferred to the neonatal intensive care unit (NICU) due to progressive respiratory failure, which ultimately, along with septicemia, led to infant death on the second day. In conclusion, the Pentalogy of Cantrell should be appropriately assessed for effective prenatal counseling and postnatal management with a multidisciplinary team; since infant survival assessment and early diagnosis give the parents the option of terminating the pregnancy.

Circumcision is one of the important public surgeries performed globally. It is a popular non-therapeutic procedure that can be performed by people of various abilities and skills, ranging from trained medical practitioners to non-specialists, depending on their cultural and social backgrounds. Consequently, this surgery may cause varying types and frequencies of complications. Glans amputation and death due to severe bleeding, as a complication of this procedure, are rare, and the patients are left with morbidity and life-long complications. Here, we describe two cases of catastrophic complications due to ritual circumcision (one penile glans amputation and one death).

Background: Acute appendicitis is a complex diagnosis that often requires both clinical and radiological evaluation. Significant variations in diagnostic approaches are evident among clinicians and healthcare institutions. While certain guidelines advocate for risk stratification based on clinical characteristics, others emphasize the importance of pre-operative imaging. This study seeks to explore the accuracy of the Alvarado Score and abdominal ultrasound (AUS) in diagnosing acute appendicitis. Methods: Suspected cases of appendicitis admitted to Al-Thora Hospital in Ibb, Yemen, from Jan 2021 to July 2022 were evaluated. The demographics, clinical, and laboratory data were collected and analyzed. This study assessed Alvarado scores (calculated based on clinical evaluation and laboratory data) and pre-operative AUS findings, correlating them with post-operative and histopathology findings. The Alvarado scores and AUS sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were assessed using the ROC curve. Results: Out of 1021 cases of acute abdomen, 171 patients were suspected of appendicitis. Using AUS along with the Alvarado score, appendicitis was presumed in 137 patients who underwent appendectomy. 130 (94.9%) patients had positive intraoperative and histopathology findings while 7 (5.1%) had negative findings. The Alvarado Score had a sensitivity and specificity of 94.62% and 87.80% at cutoffs of 6, respectively [Area under the curve (AUC): 0.985; 95% confidence interval (CI), 0.954 to 0.998; p < 0.0001]. Abdominal US showed a sensitivity of 98.46% and specificity of 82.93% (AUC:0.907; 95% CI, 0.853 to 0.946; p < 0.0001). Conclusion: Alvarado’s score and AUS exhibited high sensitivity and specificity in diagnosing acute appendicitis. The substantial accuracy and efficacy of both the Alvarado score and AUS support their utilization as primary investigative tools in resource-limited settings. This approach can help avoid unnecessary appendectomies and minimize the financial burden on patients. Plain Language Summary: Acute appendicitis poses a diagnostic challenge, with a high rate of false-positive cases identified post-operatively. Computed tomography has been recommended by several surgical societies; however, it is limited by unaffordability and unavailability. Herein, we utilized the Alvarado score along with abdominal ultrasound as an alternative accurate, and cost-effective diagnostic approach. In this study, the negative appendectomy rate was 5.1%. The sensitivity of abdominal ultrasound in detecting appendicitis was 98.5%, with a specificity of 82.9%. The positive predictive value, negative predictive value, and accuracy were determined to be 94.8%, 94.4%, and 94.7%, respectively. The mean Alvarado score was 6.9± 2.4, with a sensitivity and specificity of 97.81% and 97.06% at cutoffs of 6, respectively. The area under the curve values of the ROC curve for Alvarado’s and abdominal ultrasound were 0.985 (95% CI, 0.954 to 0.998) and (AUC:0.907; 95% CI, 0.853 to 0.946), which was statistically significant (p < 0.0001).
