Öğe Effects of testicular microlithiasis on Doppler parameters: Report ofthreecases(BioMed Central Ltd., 2002) Kutlu R.; Sigirci A.; Baysal T.; Alkan A.; Sarac K.Background: Testicular microlithiasis is a rare, usually asymptomatic, non-progressive disease of the testes associated with various genetic anomalies, infertility and testicular tumors. According to our literature search, there is no specific data about Doppler findings in this disease. Case presentation: Doppler findings of three cases of testicular microlithiasis during last two years in our institution are presented. Conclusions: Although our hypothesis was to find increased Doppler parameters due to intratesticular arterial compression, our findings suggest that there are no Doppler findings specific to testicular microlithiasis.Öğe Polyurethane stent obstruction as a cause of recurrent epiphora: Case report(Centauro SRL, 2006) Doganay S.; Sarac K.; Miman M.C.; Karadag N.; Cokkeser Y.A Song's nasolacrimal duct stent was placed in a patient with epiphora due to primary nasolacrimal duct obstruction and the stent was kept for 32 months. Mitomycin C 0.02% eye drops four times a day were prescribed for four weeks following polyurethane stent placement procedure. No epiphora-related complaints occurred for thirty months after then the epiphora started. Nasolacrimal stent was removed from nasal cavity endoscopially and the tissues within the extruded stent were examined histopathologically. The patient's complaints were relieved following stent removal. Dacryocystogram revealed normal passage and a filling defect within the lacrimal sac. Macroscopic evaluation of the stent revealed a firm mass in the stent mushroom, causing complete obstruction. Pathological examination of the mass revealed chronic inflammation, increased connective tissue and vascular proliferation. N asolacrimal polyurethane stents can be removed easily by nasal approach. Nasolacrimal passage may be left open temporarily after stent removal. The use of Mitomycin C drop is a novel approach in nasolacrimal stent placement cases. However, when the long-term results of endoscopic and external dacryocystorhinostomy are considered, further research is needed on the biocompatibility of stent material.Öğe Radiological case of the month(2004) Kutlu R.; Kocak A.; Cayli S.; Alkan A.; Sigirci A.; Sarac K.[No abstract available]
