Evaluation of olfactory bulb volume and olfactory sulcus depth in patients with panic disorder and depressive disorder: An MRI study.

Background: Although some studies have shown decreases in the olfactory bulb (OB) volume and olfactory function in depressive disorder, there are no studies investigating OB volume in patients with panic disorder. Aim: The aim of this study was to investigate whether there was a change in OB volume and olfactory sulcus (OS) depth in patients with panic and depressive disorder when compared with the control group, and which group was more affected by comparing the two disease groups. Methods: Data of 51 patients with panic disorder and 56 patients with depressive disorder were obtained by scanning the database of the hospital retrospectively. The control group consisted of 56 subjects without panic and depressive disorder. OB volume and OS depth measurements were performed on cranial magnetic resonance imaging (MRI). Results: Bilateral OB volume of the panic and depressive disorder groups were significantly lower than those of the control group. The lowest volume was found in depressive patients. There was no significant difference between the groups with respect to OS measurements. When OB volume and OS depth differences between the genders were evaluated, a statistically significant difference was not determined. Conclusion: Reduced OB volume was determined in both panic and depressive disorder patients, and clarification of these preliminary findings may contribute to the pathophysiology of panic and depressive disorders.

Relationship between appendicitis and diameter of ileocecal lipomatosis and also ileocecal angle.

PURPOSE: One of the most widespread surgical conditions is acute appendicitis in industrialized countries. Nevertheless, diagnosis of borderline cases is mostly troublesome and needs subsequent researches. For this reason, we aimed to investigate new parameters to improve estimation of acute appendicitis. Lymphoid hyperplasia, impacted stool, faecolith, caecal or appendiceal tumors have been accepted as causes of appendicitis formation, but anatomic variations of diameter of ileocecal lipomatosis and ileocecal angle have been never discussed before. The aim of this study was to assess the relationship between appendicitis and diameter of ileocecal lipomatosis and ileocecal angle. MATERIALS AND METHODS: 96 Patients (51 women, 45 men) who were found to have acute appendicitis during exploration and 67 patients (32 women, 35 men) who were not pre-diagnosed with acute appendicitis were enrolled in the study. The diameter of ileocecal lipomatosis and also ileocecal angle values were obtained via computed tomography (CT) scans. RESULTS: There were no significant differences between two groups in the mean of ileocecal angle (p > 0.05) but diameter of ileocecal lipomatosis values was significantly higher in the appendicitis-positive group compared with the appendicitis-negative group (p: 0.001). CONCLUSIONS: There is a relationship between increase in diameter of ileocecal lipomatosis and appendicitis formation.

ULTRASONOGRAPHIC EVALUATION OF FEMORAL CARTILAGE THICKNESS IN PATIENTS WITH POLYCYSTIC OVARY SYNDROME.

The aim of the study was to investigate knee cartilage thickness in polycystic ovary syndrome (PCOS) patients using ultrasonography and to assess the effects of sex steroids on osteoarthritis development. A total of 90 female patients were enrolled in the study, including 47 patients diagnosed with PCOS as study group and 43 patients admitted to our hospital for any other complaints as control group. Ultrasonographic evaluation of both knees was performed in all patients. The knee cartilage thickness was measured at lateral condyle, intercondylar area and medial condyle. The measurements were averaged for each region. The mean femoral cartilage thickness was greater in the study group compared with control group in all regions, with a statistically significant difference (p<0.005). In conclusion, we found PCOS patients to have greater mean cartilage thickness, supporting the possible effects of sex steroids on osteoarthritis development.

Olfactory bulb atrophy in migraine patients.

OBJECTIVE: Osmophobia and headache triggered by odors are commonly seen in migraine, and these are symptoms that differentiate migraine from other primary headaches. Since these odor-related symptoms are disease-specific, we aimed to measure the volume of olfactory bulb and depth of olfactory sulcus in migraine patients. PATIENTS AND METHOD: A total of 93 subjects, consisting of 62 episodic migraine (32 with osmophobia, 30 without osmophobia) patients and 31 healthy controls, were included in this study. Diagnosis and classification of migraine were performed according to the beta version criteria of International Classification of Headache Disorders (ICHD-3 Beta version). Beck depression and beck anxiety inventory were applied to the patients, and the measurement of bilateral olfactory bulb volume (OBV) and olfactory sulcus depth (OSD) was performed manually in the brain magnetic resonance imaging (MRI). RESULTS: More significantly in the left OBV, low OBV has been determined in migraine patients compared to the control group (p < 0.001, p = 0.020). When migraine patients with or without osmophobia were compared to the control group; OBV was determined to be the lowest in migraine group with osmophobia, and left-weighted bilateral OBV was determined to be low (p < 0.001, p = 0.046). No statistically significant difference was determined between groups in OSD measurements (p = 0.646, p = 0.490). CONCLUSION: Left-weighted bilateral OBV atrophy determined in migraine patients may be guiding for the clarification of migraine pathophysiology and enlightening of the relation between migraine and odor.

Magnetic Susceptibility Changes in the Basal Ganglia and Brain Stem of Patients with Wilson's Disease: Evaluation with Quantitative Susceptibility Mapping.

OBJECTIVES: Wilson's disease (WD) is characterized with the accumulation of copper in the liver and brain. The objective of this study is to quantitatively measure the susceptibility changes of basal ganglia and brain stem of pediatric patients with neurological WD using quantitative susceptibility mapping (QSM) in comparison to healthy controls. METHODS: Eleven patients with neurological WD (mean age 15 ± 3.3 years, range 10-22 years) and 14 agematched controls were prospectively recruited. Both groups were scanned on a 1.5 Tesla clinical scanner. In addition to T1- and T2-weighted MR images, a 3D multi-echo spoiled gradient echo (GRE) sequence was acquired and QSM images were derived offline. The quantitative measurement of susceptibility of corpus striatum, thalamus of each hemisphere, midbrain, and pons were assessed with the region of interest analysis on the QSM images. The susceptibility values for the patient and control groups were compared using twosample t-test. RESULTS: One patient with WD had T1 shortening in the bilateral globus pallidus. Another one had hyperintensity in the bilateral putamen, caudate nuclei, and substantia nigra on T2-weighted images. The rest of the patients with WD and all subjects of the control group had no signal abnormalities on conventional MR images. The susceptibility measures of right side of globus pallidus, putamen, thalamus, midbrain, and entire pons were significantly different in patients compared to controls (P < 0.05). CONCLUSION: QSM method exhibits increased susceptibility differences of basal ganglia and brain stem in patients with WD that have neurologic impairment even if no signal alteration is detected on T1- and T2-weighted MR images.

The association between gallstone disease and plaque in the abdominopelvic arteries.

BACKGROUND: The aim of this study was to assess the atheromatous plaque, in the abdominopelvic arteries as a marker of cardiac risk in patients with or without gallstone disease (GD). MATERIALS AND METHODS: A total of 136 patients were enrolled in this cross-sectional study. Forty-eight patients had GD and the remaining 88 patients did not. The presence or absence of gallstones was noted during abdominal ultrasonography while vascular risk factors such as plaque formation, intima-media thickness, plaque calcification, mural thrombus, stenosis, aneurysm, and inflammation were recorded during an abdominopelvic computed tomography scan. In addition, percentage of the abdominopelvic aorta surface covered by atheromatous plaque was calculated. RESULTS: The mean age of patients with GD and without GD was 50.81 ± 16.20 and 50.40 ± 12.43, respectively. Patients with GD were more likely to have diabetes mellitus, a higher body mass index (BMI) (P < 0.001), and higher cholesterol (P < 0.01), and low-density lipoprotein-cholesterol (P < 0.02) levels. No significant differences were found between the groups regarding other atherosclerotic risk factors. Patients with GD had significantly higher rates of the vascular risk factors as intima-media thickness, plaque formation, calcification, aneurysm, mural thrombosis, stenosis, and inflammation in all abdominal arterial segments other than aneurysm in the femoral arteries. In addition, patients with GD had severe atheromatous plaques in the abdominal aorta, common iliac, external iliac, and common femoral artery (CFA). In patients with GD, parameters of age, BMI, and systolic and diastolic blood pressure were all correlated with the severity of the atheromatous plaque in abdominal aorta, common iliac, external iliac, and CFA. CONCLUSION: We demonstrated a direct relationship between GD and abdominopelvic atheromatous plaque, which is a marker for increased cardiovascular risk, for the first time in the literature. Patients with GD exhibit greater abdominopelvic atherosclerosis and therefore, have a higher risk of cardiovascular disease.

Diffusion weighted imaging in differentiating malignant and benign neuroblastic tumors.

PURPOSE: Our aim was to assess diffusion weighted imaging (DWI) of neuroblastic tumors and whether apparent diffusion coefficient (ADC) value may have a role in discrimination among neuroblastoma, ganglioneuroblastoma and ganglioneuroma. MATERIAL AND METHODS: The DWIs (b = 0-800 s/mm(2)) of 24 children (13 girls, 11 boys) who were diagnosed neuroblastic tumors on histopathological examination (neuroblastoma = 15, ganglioneuroblastoma = 5, ganglioneuroma = 4) were evaluated retrospectively. The ADC maps were performed by drawing freehand ROI on PACS (Sectra Workstation IDS7, Linköping, Sweden). RESULTS: We observed a significant decrease in ADC value of neuroblastomas 0.869 ± 0.179 × 10(-3) mm(2)/s compared to ganglioneuroblastomas 0.97 ± 0.203 × 10(-3) mm(2)/s and ganglioneuromas 1.147 ± 0.299 × 10(-3) mm(2)/s (p = 0.026). There was no significant difference in between ganglioneuroblastoma and ganglioneuroma (p = 0.16). In detecting neuroblastomas; the sensitivity, specificity, negative and positive predictive values of ADC were 74, 67, 78.6, 66 % respectively with a cut-off value of 0.93 × 10(-3) mm(2)/s. CONCLUSION: Our study stands out as the most comprehensive study with larger sample size on this topic. Moreover, we are able to suggest a cut-off value which can discriminate neuroblastoma from ganglioneuroblastoma and ganglioneuroma. We believe that ADC will evolve to an objective, quantitative measurement in discrimination among malignant and benign neuroblastic tumors.

Associations of olfactory bulb and depth of olfactory sulcus with basal ganglia and hippocampus in patients with Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by hyposmia in the preclinical stages. We investigated the relationships of olfactory bulb (OB) volume and olfactory sulcus (OS) depth with basal ganglia and hippocampal volumes. The study included 25 patients with PD and 40 age- and sex-matched control subjects. Idiopathic PD was diagnosed according to published diagnostic criteria. The Hoehn and Yahr (HY) scale, the motor subscale of the Unified Parkinson's Disease Rating Scale (UPDRS III), and the Mini-Mental State Examination (MMSE) were administered to participants. Volumetric measurements of olfactory structures, the basal ganglia, and hippocampus were performed using magnetic resonance imaging (MRI). OB volume and OS depth were significantly reduced in PD patients compared to healthy control subjects (p<0.001 and p<0.001, respectively). The OB and left putamen volumes were significantly correlated (p=0.048), and the depth of the right OS was significantly correlated with right hippocampal volume (p=0.018). We found significant correlations between OB and putamen volumes and OS depth and hippocampal volume. Our study is the first to demonstrate associations of olfactory structures with the putamen and hippocampus using MRI volumetric measurements.

Cardiac and arterial elastance and myocardial wall stress in children with pectus excavatum.

OBJECTIVES: Pectus excavatum (PE) is one of the most common skeletal deformities of childhood. The study was undertaken to assess cardiac functions in children with PE. METHODS: Echocardiography was performed on 32 children with PE and 40 age-matched healthy controls. The following parameters were monitored: meridional left ventricular (LV) wall stress (WSM), arterial elastance (Ea), LV elastance at end-systole derived by single beat (Ees(sb)), LV circumferential end-systolic wall stress (ESWSc), midwall shortening fraction (SFmid), predicted midwall fiber shortening for a measured fiber stress (midwall VCFc), myocardial fiber stress (MFS), LV end-systolic dimension (LVES), LV end-diastolic dimension (LVED) and end-systolic blood pressure (Pes), LV wall thickness at end-systole (hes). To assess the severity of PE, Haller index (HI) was calculated by computed tomography of the thorax. RESULTS: SFmid, ESWSc, midwall VCFc and MFS were lower in PE children than in controls. The degree to which the parameters SFmid, ESWSc, midwall VCFc and MFS were altered in PE children was 14.9, 27.5, 20.3 and 20.3%, respectively. The minimum HI value of children with PE was 2.00, the maximum value was 4.93 and the arithmetic mean was 2.62 ± 0.56. Of the 32 children, 14 (43.75%) demonstrated mild deformity, 15 (46.88%) showed moderate and only 3 (9.37%) had severe deformity. In children with PE, there was no statistically significant correlation between the cardiac data (ESWSc, midwall VCFc, MFS, Ea, Ees(sb), LVES, LVED, Pes, hes) and HI. CONCLUSION: We found ESWSc, MFS, midwall VCFc and SFmid to be lower in children with PE than in controls. We concluded that the myocardial contractility and afterload is affected in children with PE.

Arterial Stiffness, Distensibility, and Strain in Asthmatic Children.

BACKGROUND: We hypothesized that since asthma is a chronic inflammatory disease, it could lead to the early development of atherosclerosis in childhood-onset asthma. The aim of this study was to investigate arterial stiffness, distensibility, and strain of different peripheral arteries, the parameters of which can be used to detect atherosclerosis in asthmatic children. MATERIAL/METHODS: We studied 22 pediatric patients with asthma and 18 healthy children. Fasting blood glucose and cholesterol levels were evaluated to exclude children with diabetes and hyperlipidemia, which are risk factors for atherosclerosis. Renal, carotid, and brachial arteries diameters were measured. Using the measured data, stiffness, distensibility, and strain of the arteries of all children were calculated. RESULTS: Pulse pressure, systolic and diastolic blood pressure, heart rate, cholesterols, and glucose levels of the obese individuals were similar to the controls. In carotid arteries there were no statistical differences regarding stiffness, distensibility, and strain. According to multiple ANCOVA analysis, distensibility and strain of right and left brachial arteries and right renal artery were higher, whereas right renal artery stiffness was lower in asthmatic children than in controls. Approximately one-fifth of the change in the left and right brachial arteries and right renal artery distensibility and strain and a small portion of the change in the right renal artery stiffness were associated with asthma. In contrast, left renal artery distensibility, strain, and stiffness were not associated with asthma. CONCLUSIONS: Peripheral arteries had higher distensibility and strain, and lower stiffness in asthmatic children than in controls.

Association between the corrected QT interval, carotid artery intima-media thickness, and hepatic steatosis in obese children.

OBJECTIVE: Childhood obesity is related to subclinical atherosclerosis. Carotid intima-media thickness (CIMT) and hepatosteatosis are parameters that reflect subclinical atherosclerosis and are shown to be associated with obesity. However, their relation with the corrected QT interval (QTc) has not been thoroughly studied in children. Here, we aimed to research the relation between QTc, hepatic steatosis, and CIMT among obese children. METHODS: Fifty-three obese and 53 age- and sex-matched non-obese children aged 6-16 years were included in this prospective cross-sectional study. The QTc of each subject was accordingly obtained from lead II on a 12-lead resting electrocardiogram. Thus, CIMT measurement and abdominal ultrasonographic examination were performed. The data for obese and non-obese children were analyzed and compared. RESULT: The age and gender distribution of the subjects were statistically similar. The CIMT value of the obese group was higher than that of the non-obese group (p<0.001). The obese group had a higher frequency of hepatosteatosis at grade 1 or 2 than the non-obese group (p<0.001). The QTc values were also found to be more prolonged in the obese group than in the other group (p<0.001). With Student's t-test and Mann-Whitey U test accordingly. CONCLUSION: We demonstrated that obese children had higher CIMT and QTc values as well as more frequent hepatosteatosis, and that the presence of hepatosteatosis or increased CIMT had an association with prolonged QTc values in obese children. Therefore, with the aim of detecting cardiovascular effects of obesity, it may be beneficial to perform the measurements of QTc in the presence of hepatosteatosis and/or increased CIMT among obese children.

Hepatic vein and portal vein Doppler ultrasound of maternal liver in normal pregnancy.

OBJECTIVE: The purpose of our study was to evaluate the changes occurring in maximum flow velocity and waveform patterns of the portal and hepatic veins during pregnancy in second and third trimesters. METHODS: A total of 204 patients were randomly divided into the study and control groups. The control group was classified as group I; the study group was divided into two groups: group II, second trimester pregnancy (14-26 weeks, n = 91) and group III, third trimester pregnancy (26-40 weeks, n = 63). Vein waveforms were classified as triphasic, biphasic and monophasic. RESULTS: Maximum flow velocities of both right hepatic vein and main portal veins were lower in group III compared with group I and group II (p < 0.05). On the basis of hepatic vein and portal vein waveforms, the incidence of biphasic pattern was prominent in group II (p < 0.05) whereas the monophasic pattern was prominent in group III (p < 0.05). CONCLUSION: The results demonstrate that as gestational age progresses, maximum flow velocities of both right hepatic vein and main portal veins intend to be decreased with an increased incidence of monophasic wave form pattern, and may be accepted as sensitive parameters of indicators of physiological adaptations related to pregnancy.

Olfactory bulb and olfactory sulcus depths are associated with disease duration and attack frequency in multiple sclerosis patients.

BACKGROUND AND PURPOSE: Multiple sclerosis (MS) is a neuroinflammatory and neurodegenerative disease that progresses to axonal loss and demyelinization. Olfactory dysfunction in patients with MS has been reported frequently. We were interested in the associations of olfactory bulb (OB) and olfactory sulcus depth (OSD) with disease duration and attack frequency. METHODS: We included 25 patients with MS and 30 age- and sex-matched controls in this study. The Expanded Disability Status Scale, Beck Depression Inventory, and Mini Mental State Examination were applied. OB, OSD, and magnetic resonance imaging plaque numbers were calculated. RESULTS: OB volume and OSD in patients with MS were significantly lower than those in the control group (right and left OB: p<0.001; right OSD: p=0.001; and left OSD: p=0.039). Disease duration was negatively correlated with right and left OB volume (right OB: r=-0.434, p=0.030 and left OB: r=-0.518, p=0.008). Attack frequency was negatively correlated with left OB volume and left OSD (left OB: r=-0.428, p=0.033 and left OSD: r=-0.431, p=0.032). CONCLUSIONS: The OB and OSD were atrophied significantly in patients with MS, and this was correlated with disease duration and attack frequency. The left side tended to be dominant.

The evaluation of carotid intima-media thickness and mean platelet volume values and correlation with cardiac functions in obese children.

BACKGROUND: Obesity is associated with many risk factors, such as hyperlipidemia, hyperinsulinemia, hypertension and leads to early atherosclerosis. The aim of this study was to investigate the relation of the mean platelet volume (MPV) and the carotid intima media thickness (CIMT) on cardiac functions among obese children. MATERIALS AND METHODS: Sixty obese children, with body mass index percentile were >95% and forty eight healthy controls were enrolled in the study. Triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase (ALT), aspartate aminotransferase (AST), thyroid function tests, hemoglobin, white blood cell, MPV and insulin resistance were evaluated. CIMT was measured by using high-resolution ultrasound and echocardiography was performed to all individuals. RESULTS: MPV and CIMT values were found significantly higher in obese children than controls. There was positive correlation between CIMT and age, body surface area (BSA), systolic and diastolic blood pressure, left ventricular meridional end-systolic wall stress (ESWSm), myocardial fiber stress (MFS), stroke volume (SV) and insulin and negative correlation with left ventricle end-systolic elastance by single beat technique (Ees(sb)) and arterial elastance (Ea). There was no correlation between LVM, cardiac risk profiles and CIMT. Multiple stepwise regression analyses revealed that ESWSm (ß=0.337, P=0.049) was only independent factor on CIMT. MPV values showed negative correlation with ALT, AST, Free T4, thyroid stimulating hormone and positive correlation with age and BSA. CONCLUSION: Current study showed that obesity has an independent impact on CIMT and MPV values in children. Increased CIMT in obese children leads significant increase in ESWSm and decrease in Ea and Ees(sb).

Relationship between kidney volume and body indexes in the Turkish population determined using ultrasonography

Objective To estimate the kidney volume of the healthy Turkish population using ultrasound and to evaluate the relationship between kidney volume and body indexes. Materials and methods Kidney ultrasound evaluation was performed on 152 patients (mean age: 42±13.7 years). Kidney length, width and thickness were measured using ultrasound. Mean total and parenchymal volume were also calculated. Patients’ age, sex, weight, height and body mass index (BMI) (kg/m2) were recorded. Results According to ultrasound, kidney lengths were 10.3±7.8 cm for the right and 10.4±9 cm for the left. Volumes were 158±39 cm3 for the right and 168±40 cm3 for the left. Volumes in women were 151.8±39 cm3 for the right and 159.8±37 cm3 for the left, and 164.3±38 cm3 for the right and 175.8±41 cm3 for the left in men. Kidney measurements correlated with body height and weight. A strong correlation with total kidney volume and kidney measurements was determined for body weight for both kidneys (p<0.001). A significant correlation with kidney volume and width was determined for both kidneys (p<0.001). A positive correlation was also found between parenchymal and total kidney volume for both kidneys (p<0.001). Conclusion The most significant factors associated with kidney volume for both kidneys in the Turkish population are kidney width and body weight. Measuring kidney volume with ultrasound is a feasible modality and is widely available for daily clinical practice. .

Catamenial hemoptysis: a case report.

Herein we present a 25-year-old female patient who was admitted with recurrent hemoptysis in menstrual period. At the thorax computed tomography taken during menstruation of patient, diffuse ground glass density and acinar nodules at superior segment of lower lobe at left lung were detected. There was no this findings at the thorax tomography taken in non-menstruation period. Therefore, patient was considered catamenial hemoptysis with clinical and radiological findings. Pulmonary endometriosis is rarely seen disease of the lung, so we are presenting it in the light of the literature knowledge.

Recurrent pulmonary embolism in an asthmatic patient who had interrupted inferior vena cava with azygous continuation.

A 45-year-old woman with a history of recurrent pulmonary embolism was admitted to the emergency clinic with dyspnea, wheezing and tachypnea. Partial deep vein thrombosis of the popliteal vein was seen on Doppler sonography. On the contrast-enhanced thorax computed tomography (CT) scan, a clot was detected in the right main pulmonary artery and its major descending branch. Moreover, the azygos vein was prominently dilated. Abdominal multi-slice computed tomography (MSCT) scan revealed absence of the hepatic segment of the inferior vena cava (IVC) with continuation of the IVC as a dilated right-sided azygos vein. The hepatic veins were draining directly into the right atrium. Thus, we discuss herein this rare anatomic variant presented with recurrent pulmonary embolism, together with the findings on MSCT.

Is there a relationship between symptoms of patients and tomographic characteristics of styloid process?

OBJECTIVES: To investigate the angulations and length of the styloid process (SP) on three-dimensional computed tomography (3D-CT) images between the patients having elongated SP complaints and those without any stylalgia symptoms. PATIENTS AND METHODS: One hundred patients underwent 3D-CT evaluation of the bilateral temporomandibular joints to investigate for symptomatic elongated styloid process (ESP) at our institution. The differences between the mean angulations and lengths of the SP and comparisons between patient and control groups were analyzed by student t test. RESULTS: In study group, mean length of styloid processes was 40.7 ± 10.8 mm on the right and 40.3 ± 10.9 mm on the left. Mean medial angles of SP were measured as 22.60 ± 4.0 on the right side and 22.60 ± 4.5 on the left side. In the same group, mean anterior angles of SP were 16.10 ± 6.9 on the right and 16.70 ± 7.1 on the left side. The "in-group" comparisons of lengths, medial and anterior angles did not produce statistically significant results. The comparison of medial angulations between the symptomatic and asymptomatic patients was the only statistically meaningful result in our study. CONCLUSION: 3D-CT has several advantages according to conventional tomography for visualization of head and neck anatomy. The increase of medial angulation of SP may be responsible for the development of complaints in ESP.

Relationship between kidney volume and body indexes in the Turkish population determined using ultrasonography.

OBJECTIVE: To estimate the kidney volume of the healthy Turkish population using ultrasound and to evaluate the relationship between kidney volume and body indexes. MATERIALS AND METHODS: Kidney ultrasound evaluation was performed on 152 patients (mean age: 42 ± 13.7 years). Kidney length, width and thickness were measured using ultrasound. Mean total and parenchymal volume were also calculated. Patients' age, sex, weight, height and body mass index (BMI) (kg/m²) were recorded. RESULTS: According to ultrasound, kidney lengths were 10.3 ± 7.8 cm for the right and 10.4 ± 9 cm for the left. Volumes were 158 ± 39 cm3 for the right and 168 ± 40 cm3 for the left. Volumes in women were 151.8 ± 39 cm3 for the right and 159.8 ± 37 cm3 for the left, and 164.3 ± 38 cm3 for the right and 175.8 ± 41 cm3 for the left in men. Kidney measurements correlated with body height and weight. A strong correlation with total kidney volume and kidney measurements was determined for body weight for both kidneys (p<0.001). A significant correlation with kidney volume and width was determined for both kidneys (p<0.001). A positive correlation was also found between parenchymal and total kidney volume for both kidneys (p<0.001). CONCLUSION: The most significant factors associated with kidney volume for both kidneys in the Turkish population are kidney width and body weight. Measuring kidney volume with ultrasound is a feasible modality and is widely available for daily clinical practice.
