Gender and side distribution of urinary calculi using ultrasound imaging.

INTRODUCTION: Urinary calculi constitute a significant medical problem worldwide. Due to lack of previous studies on gender and side distribution of urinary calculi, the current study was conducted. PATIENTS AND METHODS: This retrospective study involved 590 urinary calculi from the electronic reports of 266 patients. Gender and side distribution were compared using Chi-square test. Relationship between gender and side of urinary calculi was analyzed using cross tabulation test. RESULTS: This study involved 590 urinary calculi reported in 266 patients. Among 590 calculi; 565 (95.8%) were in adults, and 25 (4.2%) were in children. Urinary calculi were in male in 397 (67.3%) and in female in 193 (32.7%). Calculi were 304 (51.5%) in right side, and 286 (48.5%) in left side. Exactly 507 (85.9%) of calculi were in the kidneys, and 83 (14.1%) in the ureters. No significant relationship between gender and side of the calculi (P = 0.238), (Odds ratio 0.869, 95% Confidence interval 0.615-1.226). CONCLUSION: Urinary calculi affect male more than female and adults more than children. No significant relationship between calculi and right or left side of the body.

Doppler sonographic assessment of carotid arteries in Sudanese stroke patients.

BACKGROUND: Hypertension, diabetes, and smoking were considered to be associated with several public health problems. OBJECTIVE: the study aims to explore the hemodynamic of carotid arteries in association with hypertension, diabetes, and smoking in Sudanese stroke patients. MATERIALS AND METHODS: In a quantitative descriptive study, fifty patients with stroke were scanned by B-mode and Doppler sonography. Carotid arteries were investigated with a 7-MHz linear transducer by a standard carotid sonography protocol. RESULTS: The average Doppler resistive index (RI) was 0.71 ± 0.084 and intima-media thickness was 1.39 ± 0.78 mm. The end diastolic velocities (EDVs) and peak systolic velocities (PSVs) of common carotid arteries were significantly changed in smokers and hypertensive (P < 0.05). The elevation of RI in right and left CCAs were significantly correlated with smokers (P = 0.017 and 0.010 respectively). Hemorrhagic stroke was most prevalent in hypertensive rather than diabetic and smokers. The carotid hemodynamics changed significantly in hypertensive and smokers more than diabetics. CONCLUSION: EDV and PSV were significantly correlated with hypertension and tobacco smoking rather than diabetes. Hypertension, diabetes, and smoking have an association with stroke and hand significant effect on carotid artery hemodynamic and atherosclerotic disease. The Doppler RIs were significantly correlated with smokers. Patients with risk factors of stroke should be scanned with Doppler sonography as early as possible.
