Öğe Case Report: Spontaneous urinoma: Combined treatment with percutaneous and endoureteral catheterization(2005) Yazıcı, Burhan; Kayıkçı, Ali; Erdoğmuş, Beşir; Cam, Kamil; Büyükkaya, RamazanA urinoma is defined as encapsulated collection of chronically extravasated urine. Obstruction of the ureter by calculus, surgical ligature, neoplazms, or obstruction at the bladder outlet, such as by posterior urethral valves, is the most common cause of the urinomas. Spontaneous urinoma during renal colic is rare. Here, we present a case with spontaneous urinoma occured during an attack of renal colic. In addition, treatment strategies of urinomas caused by different etiologies are discussed with the scope of the current literature.Öğe Orbital blood flow velocities in patients with rheumatoid arthritis(Wiley, 2007) Erdoğmuş, Beşir; Yazıcı, Selma; Yazıcı, Burhan; Ataoğlu, Safinaz; Büyükkaya, Ramazan; Yüksel, Harun; Cura, SibelPurpose. To assess orbital blood flow changes in patients with rheumatoid arthritis using Doppler sonography. Patients and Methods. The study comprised 35 patients who were diagnosed with RA and were treated at the Department of Physical Therapy and Rehabilitation at Duzce Medical School. A control group consisted of 35 healthy volunteers. Color Doppler imaging was used to measure peak systolic velocity (PSV) and end diastolic velocity (EDV), from which the resistance index (RI) was calculated in the ophthalmic artery (OA), central retinal artery (CRA), and posterior ciliary arteries (PCAs). Results. In the CIA, PSV, EDV, and RI were, respectively, 36.7 +/- 0.6 cm/sec, 9.7 +/- 0.2 cm/sec, and 0.73 in the control group versus 34.7 +/- 3.0 cm/sec, 9.1 +/- 1.1 cm/sec, and 0.74 in the patient group. In the CRA, they were, respectively, 11.8 +/- 1.7 cm/sec, 3.6 +/- 0.7 cm/sec, and 0.66 in the control group versus 11.1 +/- 1.7 cm/sec, 3.4 +/- 0.7 cm/sec, and 0.68 in the patient group. In the PCAs, they were, respectively, 13.2 +/- 1.2 cm/sec, 4.7 +/- 0.6 cm/sec, and 0.65 in the control group versus 12.4 +/- 1.2 cm/sec, 4.2 +/- 0.6 cm/sec, and 0.66 in the PCAs. PSV, EDV, and RI of the PCAs and OA and RI of the CRA were significantly different between patients-and controls, whereas there was no difference in the serum levels of glucose, triglyceride, low-density lipoprotein cholesterol, and total cholesterol. In the patient group, there was a significant correlation between orbital blood flow and duration of disease. Conclusion. Ocular blood flow appears to be slightly lower in RA patients than in healthy controls, suggesting that RA is a systemic inflammatory disease that may also involve ocular vessels.

Doppler sonography is used as a diagnostic method in the non-invasive assessment of the hemodynamics of hepatic vascular flow in liver diseases. We investigated the effects of fatty infiltration in the liver on the Doppler flow hemodynamics of the portal vein. Doppler sonography of the liver and portal vein was performed in 60 subjects with NAFLD and 20 healthy volunteers (control). The patients were grouped into mild (grade 1), moderate (grade 2), and severe (grade 3) according to sonographic appearance of hepatosteatosis (n = 20 for each group). The vein pulsatility index (VPI), mean flow velocity (MFV), peak maximum velocity (V-max), and peak minimum velocity (V-min) of the portal vein were significantly lower in patients with NAFLD than those of the controls (p < 0.001). The VPI was 0.20 in the patients and 0.31 in the control. The MFV was 12.3 cm/sec in the patients and 16.5 cm/sec in the control group. The portal vein flow was found to be decreased as the grade of fatty infiltration increased for VPI (r = -0.946, p < 0.001),MFV(r=-0.951,p < 0.001). The alteration in Doppler waveform pattern of portal vein with fatty liver population suggests reduced vascular compliance in the liver.Öğe The prevalence of venous insufficiency in patients with chronic obstructive pulmonary disease evaluated by color duplex ultrasonography(Springer Wien, 2006) Erdoğmuş, Beşir; Annakkaya, Ali Nihat; Yazıcı, Burhan; Bulut, İsmet; Özdere, Betül Ayça; Büyükkaya, RamazanObjectives: We hypothesized that in patients with chronic obstructive pulmonary disease (COPD) some extrapulmonary effects such as increase in intra-abdominal and intra-thoracic pressures, presence of cor pulmonale and pulmonary artery hypertension could cause venous insufficiency (VI) in the lower limbs. Our aim in this study was to assess the prevalence of VI in patients with COPD in comparison with healthy controls. Methods: Thirty-nine male patients with COPD and 36 healthy male controls were evaluated for VI. All the participants were in the same age group and their smoking intensities were similar. Patients with COPD were classified as having mild, moderate, severe or very severe disease according to criteria of the Global Initiative for Chronic Obstructive Lung Disease. All the patients and control group were examined for unilateral or bilateral VI of the common femoral vein, superficial femoral vein, deep femoral vein and popliteal vein using color duplex ultrasonography. Results: The prevalence of VI of the lower extremity in patients with COPD (69.2%) was significantly higher than in the healthy control group (41.7%). The prevalence increased as the COPD severity increased and VI was detected in all the patients with very severe COPD [mild COPD, 50.0% (2/4); moderate, 58.8% (10/17); severe, 75.0% (9/12); very severe, 100% (6/6)]. Conclusion: VI of the lower extremity appears more frequent in patients with COPD. We suggest ruling out COPD in patients with otherwise unexplained "primary" VI.Öğe The relationship of bone mineral density with carotid intima-media thickness and hemodynamics(Nobel İlaç, 2013) Büyükkaya, Ramazan; Yazıcı, Selma; Erdoğmuş, Beşir; Ataoğlu, Safinaz; Özşahin, MustafaObjective: Cardiovascular diseases and osteoporosis are the most important two causes of morbidity and mortality in postmenopausal women. In this study, we classified postmenopausal women, who are free of cardiovascular diseases, according to their bone mineral density. We aimed to evaluate the effect of bone mineral density on carotis intima media thickness and hemodinamia. Material and Method: Bone mineral density of the patients was defined by using World Health Organization's T score. A total of 120 patients were divided into 3 equal groups as patients with T scores greater than -1.0 (normal), patients with T scores between -1.0 and -2.5 (osteopenics), and patients with T scores lower than -2.5 (osteoporotics). Results: When the osteoporotic, osteopenic, and normal groups were compared, no significant difference was found in terms of peak systolic and end-diastolic velocities. According to groups mean age of patients are 53.18 +/- 0.612 in normal group 55.88 +/- 0.927 in osteopenic group and 60.68 +/- 1.155 in osteoporotic group. There is not significant statistical difference between normal group and osteopenic patients (p>0,05) Between OP and other groups there is significant statistical difference (p<0,05). A reverse-linear correlation was observed between age and lomber T score, and between lomber T score and intima media thickness. A linear correaltion was found between age and intima media thickness (r=0.41, p<0.001, R-2=0.166). Residual index values were siginificantly different between normal subjects and osteopenic patients (p<0.05) whereas no difference was found between other groups (p>0.05). Conclusion: In the present study, an increase in the lomber vertebrae bone mineral density was shown to be associated with an increase in carotid intima media thickness.Öğe Renal replasman lipomatozisin BT bulguları(2005) Erdoğmuş, Beşir; Yazıcı, Burhan; Bahçebaşı, Bicik Zerrin; Büyükkaya, RamazanRenal replasman lipomatozis (RRL), kronik taş hastalığına ve hidronefroza bağlı olarak gelişen böbrekte atrofi, renal sinüs, renal parankim ve perirenal alanda yağ dokusunda belirgin artış ile karakterize nadir bir hastalıktır. RRL'nin tanısı tümöral patolojileri taklit etmesi nedeni ile önemlidir. RRL'in tanısı bilgisayarlı tomografi (BT) ile yüksek oranda doğru olarak konulabilmektedir. Bu yazıda, RRL'li bir olgunun BT bulguları sunularak literatür bilgileri eşliğinde tartışılmıştır.Öğe Tunica albuginea kisti ve eşlik eden skrotal kalkül olgusu(2013) Büyükkaya, Ramazan; Büyükkaya, Ayla; Erdoğmuş, Beşir; Yazici, Burhan; Şafak, Alp Alper; Çalişkan, Mustafa; Yazgan, ÖmerUltrasonografinin üroloji pratiğinde kullanımının yaygınlaşması sonucu testiküler lezyonlarla daha sık karşılaşılmaktadır. Testis ile ilişkili kistler basit kist, tunika albuginea kisti,epidermoid kist ve rete testis ektazisi olarak sınıflanabilir.Tunika albuginea kaynaklı kistler oldukça nadirdir, bu kistlerkapsül kaynaklı olup testis çevresinde yerleşir. Tunica albuginea kistleri genelde insidental saptanmalarına rağmenhastalar ağrı, şişlik ve iğne başı büyüklüğünde sert bir kitle ilebaşvurabilirler. Bu kistlerin mezotelyal orijinli oldukları düşünülmektedir. Fizik muayenede tunica albuginea kistleriyanlışlıkla malign testiküler tümörlerle karışmasına rağmensonografi ile doğru tanı koyularak gereksiz cerrahiden kaçınılmalıdır. Biz bu yazıda, tunica albuginea kisti ve scrotalkalkül tanısını eş zamanlı olarak koyduğumuz bir olguyusunduk.
