To evaluate the possible role of ureteral wall thickness (UWT) assessment in the prediction of the success for stent placement in cases with obstructing ureteric stones. 227 adult patients with a single unilateral obstructing ureteral stone requiring internal ureteral stent placement were included. In addition to stone size, the ureteric wall thickness at the impacted stone site and the degree of hydronephrosis were also assigned on CT images. Patients were divided into two subgroups: Group 1: patients in whom internal ureteral stent could not be passed beyond the stone and Group 2: patients in whom an internal ureteral stent was passed successfully. The possible relationship between the UWT values and the success of stent placement, degree of hydronephrosis were comparatively evaluated. The majority of the stones were located in the proximal ureter in Group 1 and the degree of hydronephrosis was also higher in these cases. Moreover, while the mean value of UWT calculated on CT images was 4.3 ± 0.9 mm in Group 1, this value was noted to be 2.5 ± 0.8 mm in cases of group 2. A cutoff UWT value of 3.35 mm was highly predictive for the stent insertion and cases with higher values required additional procedures or percutaneous nephrostomy tube placement. UWT value calculated at the obstructing stone site was found to be predictive enough for the likelihood of internal ureteral stent passage with high sensitivity and specificity. This evaluation may enable the urologist to make the best decision for urinary diversion in such cases.

Araştırma Kayseri Melikgazi Eğitim ve Araştırma Sağlık Grup Başkanlığı Bölgesinde gebe kadınların gebelikte beslenme konusundaki bilgi düzeyleri ve beslenme durumunu saptamak amacıyla tanımlayıcı olarak yapılmıştır.Gebeliklerinin II. trimesterinde (4.5.6. aylarında) olan 375 gebe araştırma kapsamına alınmıştır. Araştırmanın verileri gebe kadınların gebelikte beslenme konusundaki bilgi düzeyleri ve beslenme durumunu saptamaya yönelik olarak hazırlanan; 54 soru içeren anket formu ile toplanmıştır. Araştırmadan elde edilen veriler, SPSS 13.0 programı yardımı ile değerlendirilmiştir. Normal dağılım göstermeyen değişkenler için Kruksal Wallis analizi kullanılmıştır. Verilerin normal dağılıp dağılmadığına Kolmogorov-Simirnov testiyle bakılmıştır. Nitel değişkenlerin karşılaştırılmasında Khi-Kare testinin exact yöntemi kullanılmıştır.Araştırma kapsamına alınan gebelerin yaş ortalaması 27.16± 5.4 yıldır. Gebelerin %85.3'ü ev kadını, %71.2'si çekirdek aileye sahiptir. Kendi değerlendirmelerine göre, %56.3'ünün ekonomik durumu orta, %58.7'si SSK'lıdır. Gebelerin %96.8'i ebe izlemi almıştır. %99.2'si doktor kontrolünden geçmiştir. %13.1'i gebelikten önce folik asit kullanmış, %95.5'i ise gebelikte vitamin-mineral desteği almıştır.Gebelerin besin gruplarından gebelik öncesine göre et-yumurta-kurubaklagil, süt ve süt ürünleri, sebze-meyve gruplarından tüketimi bilme oranları sırasıyla, %85.1, %92.5, %93.6 olarak yüksek oranlarda bulunmuştur, ancak tahıllar ve yağ-şeker gruplarının aynı miktarda tüketilmesi gerektiğini bilenlerin oranı sırasıyla %18.7 ve %5.9 olarak düşük bulunmuştur.Besin grupları tüketim durumları incelendiğinde yetersiz tüketim, et, yumurta, kurubaklagiller grubunda en yüksektir (%86.7), bunu süt ve süt ürünleri izlemektedir (%48.8), fazla tüketim ise, sebze ve meyve grubunda en yüksek (%50.4) bulunmuştur, tahıllar (%43.7) bunu izlemektedir. Gebelerin gebelik öncesi BKİ değerlendirmesine göre %52.3'ü normal, %26.1'i fazla kilolu, %15.5'i zayıf, %6.1'i obez bulunmuştur. Araştırmamızda gebelerin yarısından fazlasının (%55.4) gebelikteki ağırlık kazanımı fazla bulunmuştur.Anahtar Kelimeler: Beslenme, Beslenme Durumu, Bilgi, Gebelik This descriptive study was conducted to determine the nutritional knowledge level and nutrition status of pregnant women regarding pregnancy in Kayseri Melikgazi Education Research Health Group Center Area.Totally, 375 pregnant women in the second trimester (4-6th months) were included. The data was obtained by a structured questionnaire consisting of 54 items regarding the nutritional knowledge level and nutrition status of pregnant women on pregnancy. The data was analyzed through SPSS 13.0 program. Abnormally distributed data was analyzed by Kruskal-Wallis test. Normal distribution of data was analyzed by Kolmogorov-Smirnov test. Chi-square exact test was performed to compare qualitative variables.The mean age of the pregnant women were 27.16± 5.4 years. Of the pregnant women; 85.3% were housewives, 71.2% have nuclear family. According to their self-reports; 56.3% represent moderate socio-economic level and 58.7% have health insurance. 96.8% of the pregnant women were followed by midwives. 99.2% have medically followed by physician. 13.1% used folic acid supplements before pregnancy and 95.5% used vitamin-mineral supplements during pregnancy.The true knowledge status of the pregnant women on food groups to be increased during pregnancy were high as 85.1%, 92.5%, and 93.6%, respectively for meat-egg-legumes, milk and milk products, vegetable-fruit group; however the true knowledge on cereals and fat-sugar groups were low as 18.7% and 5.9%, respectively.According to food group consumption; the highest inadequate consumption were determined for meat-egg-legumes group (86.7%), followed by milk and milk products (48.8%), the highest adequate consumption were determined for vegetable-fruit group (50.4%), followed by cereals group (43.7%). According to weight evaluation by body mass index (BMI) before pregnancy; 52.3% were normalweight, 26.1% were overweight and 15.5% were lean and 6.1% were obese. In the current study, more than half of the pregnant women (55.4%) gained extra weight.Key words: Nutrition, Nutritional Status, Knowledge, Pregnancy 121
