Öğe Bellini duct carcinoma of kidney: A case report(1998) Çal, Çağ; Keskin, Derya; Akalın, Taner; Günaydın, Gürhan; Killi, Refik; Kandiloğlu, GülşenCollecting duct carcinoma (CDC) is an unusual variation of renal cell carcinoma. During evaluation of a 64 year old man presenting intermittent hematuria, it was detected right kidney tumor. Radical nephrectomy was performed after embolization of renal artery. He died with multiple organ métastases at the end of the first month after operation. There is no sufficient data about clinical course and treatment of the CDC. Radical nephrectomy is the treatment option for the localized disease.Öğe Prostat patolojilerinde transrektal ultrasonografi ile tanı(Ege Üniversitesi, 1990) Killi, RefikÖZET Transrektal ultrasonogram, prostat patolojilerinin değerlendirilme sinde kullanılan en önemli tanı yöntemidir. Bu çalışmamızın amacı, çeşitli prostat patolojilerindeki transrektal sonografik tanı kriterlerini belirlemek ve bu kriterlerin benign ve malign lezyonların ayrımı üzerindeki etkin liğini tartışmaktır. Çalışma grubumuzda yer alan toplam 300 hasta, Ege Üniversitesi Tıp Fakültesi, Radyodiagnostik. Ana Bilim Dalı, Ultrasonografi Bölümünde incelenmiştir. Serimize dahil edilen tüm olguların kesin tanıları, cerrahi ve his- topatolojik olarak belirlenmiştir. Prostat patolojilerinde saptanan transrektal sonografik tanı kriterleri, çoğu zaman benignite ve malignite arasında yeterli ayrımın yapılmasına olanak vermemektedir. Bu nedenle, prostat kanseri açısından şüpheyle karşılanan her lezyona, transrektal ultrasonografi rehberliğinde biopsi girişiminin uygulanması, doğru tanı şansını büyük ölçüde arttıracaktır. 112Öğe A rare case of granulomatous prostatitis caused by Mycobacterium tuberculosis(John Wiley & Sons Inc, 2007) Tamsel, Sadyk; Killi, Refik; Ertan, Yesim; Demirpolat, GulgunWe report a rare case of infective granulomatous prostatitis caused by Mycobacterium tuberculosis that may be mistaken for prostatic carcinoma, both on clinical examination and transrectal sonography (TRUS). A large hypoechoic mass was detected in the prostate of a 46-year-old man during TRUS and histopathologic examination after TRUS-guided biopsies reported the diagnosis of tuberculous prostatitis. We herein describe the clinical and TRUS findings of this case.

Materials and methods: MR portography findings were retrospectively compared with the results of CDUS examinations in 161 patients, who were suspected of having portal venous system abnormalities. Portal venous vessels were divided into main 5 groups including the main portal vein, its left and right intrahepatic branches, splenic vein and superior mesenteric vein. Imaging findings were classified as normal, occluded, or partially thrombosed. Results of clinical and imaging follow-up examinations including CDUS, MR portography or angiography, if available, were used as a proof of final diagnosis. The potential sites of varicose veins and collateral vessels were also examined by both imaging methods. Results: Vascular abnormalities were identified in 79 of 161 patients. There was a statistically significant agreement between the results of MR portography and CDUS in evaluating portal venous system (kappa = 0.871, P < 0.05). The sensitivity of MR portography was slightly superior to CDUS in detecting partially thrombosis and occlusion in the main portal venous vessels. In addition, MR portograms were superior to CDUS in the management of patients with portal hypertension by identifying portosystemic collaterals more adequately, and clearly demonstrated portal venous vessels that cannot be visualized at CDUS. Conclusion: Results of present study indicates that contrast-enhanced 3D MR portography is well suited and superior to CDUS in the management of patients with portal hypertension.Öğe Using marginal right lobe living liver donors: Safety of expanding the margins(Blackwell Publishing, 2007) Dayangac, Murat; Taner, Burcin C.; Akin, Baris E.; Balci, Deniz; Uraz, Suleyman; Duran, Cihan; Killi, Refik; Ayanoglu, Omer H.; Yuzer, Yildiray; Tokat, YamanÖğe Vascular complications after liver transplantation: evaluation with Doppler US(Springer, 2007) Tamsel, Sadik; Demirpolat, Gulgun; Killi, Refik; Aydin, Unal; Kilic, Murat; Zeytunlu, Murat; Parildar, Mustafa; Oran, Ismail; Ucar, HakanPurpose: To demonstrate the spectral and color Doppler ultrasonography (US) findings that would indicate vascular complications after liver transplantation and to report our single center results of vascular complications detected in liver transplant recipients. Materials and methods: Our study was consisted of 326 patients who underwent liver transplantation procedures between November 1997 and May 2004. The records of all patients were reviewed retrospectively for the details of each patient's post-transplant Doppler US examinations, visceral angiographic examinations, and/or surgical procedures. Doppler US findings were correlated with angiographic results or surgery. Sensitivity and specificity of Doppler US parameters for the diagnosis of vascular complications of the hepatic artery, portal vein, and hepatic veins were calculated. Results: Vascular complications occurred in 47 patients (14%). Eight instances of vascular complications were detected intraoperatively by Doppler US at the time of transplantation. For hepatic artery complications, use of a Doppler US criteria resulted in a sensitivity and a specificity of 92% and 97%, respectively. Doppler US parameters also resulted in a sensitivity and a specificity of 100% in detecting portal vein complications, and resulted in a sensitivity of 99% and a specificity of 100% in detecting hepatic vein complications. Conclusion: Although it is clear that Doppler US evaluation is an effective choice for diagnosing vascular complications after liver transplantation, we also observed that Doppler US examination plays an important role in detecting vascular complications intraoperatively and improving the patient's chance for a successful outcome.
