Karadeniz-Bilgili, MY; Basar, H; Simsir, I; Unal, B; Batislam, E (Springer-Verlag, 2003)Background. Although there is much evidence supporting a relationship between primary varicocoele and venous incompetence of the saphenofemoral junction in adults, there is no evidence for such a relationship during ... -
Ceftriaxone-induced symptomatic pseudolithiasis mimicking ICP elevation
Evliyaoglu, C; Kizartici, T; Bademci, G; Unal, B; Keskil, S (Johann Ambrosius Barth Verlag Medizinverlage Heidelberg Gmbh, 2005)In neurosurgery, ceftriaxone is a widely used, third generation cephalosporin for the treatment of CNS infections and perioperational prophylaxis. Recent studies have demonstrated that ceftriaxone induces reversible ... -

Contrast media induces hypoperfusion in kidneys with ureteral stone: Doppler us study
Unal, B; Kara, S; Bilgili, Y (Elsevier Science Inc, 2005)We aimed to assess the hemodynamic effects of nonionic low-osmolarity contrast media (CM) on kidneys with ureteral stone (KUS). A total of 16 patients with KUS (group A) and 25 control patients (group B) were evaluated ... -
Doppler sonography of the normal lacrimal gland
Bilgili, Y; Taner, P; Unal, B; Simsir, I; Kara, SA; Bayram, M; Alicioglu, B (Wiley, 2005)Purpose. We used Doppler sonography to determine the resistance index (RI) and pulsatility index (PI) of the normal lacrimal artery (LA) in both females and males. We also compared the values obtained at various periods ... -
Effect of oxymetazoline nasal spray on intraocular pressure and retrobulbar hemodynamics
