We evaluated the impact of transrectal prostate needle biopsy (TPNB) on erectilefunction and on the prostate and bilateral neurovascular bundles using power Doppler ultraso-nography imaging of the prostate. The study consisted of 42 patients who had undergone TPNB.Erectile function was evaluated prior to the biopsy, and in the 3rd month after the biopsy usingthe ﬁrst ﬁve-item version of t he International Index of Erectile Function (IIEF-5). Prior to and3 months after the biopsy, the resistivity index of the prostate parenchyma and both neurovas-cular bundles was measured. The mean age of the men was 64.2 (47e78) years. Prior to TPNB, 10(23.8%) patients did not have erectile dysfunction (ED) and 32 (76.2%) patients had ED. The meanIIEF-5 score was 20.8 (range: 2 e25) prior to the b iopsies, and the mean IIEF-5 score was 17.4(range: 5e25; p < 0.001) after 3 months. For patients who were previously potent in the pre-biopsy period, th e ED rate was 40% (n Z 4/10) at the 3rd month evaluation. In these patients,all the resistivity index value s were signiﬁcantly decreased. Our results showed that TPNB maylead to an increased risk of ED. The presence of ED in men after TPNB might have an organic basis.Copyright ª 2013, Kaohsiung Medical University. Published by Elsevier Taiwan LLC. All rightsreserved

Relationship between the nat genetic polymorphism and susceptibility to prostate cancer Dilek, Derya; Güray, Tülin; Department of Biology (2008) Prostate cancer (PCa) is one of the most prevelant cancers in males in many countries, increasing in frequency with age. PCa incidence and mortality rates are not evenly distributed worldwide. Family history is an established risk factor for prostate cancer and families demonstrating autosomal dominant or X-linked transmission of susceptibility have been observed. Although an increasing number of candidate genes or hereditary prostate cancer susceptibility have been identified, only 5 to 10 percent of prost...
Investigating the Performance of Generative Adversarial Networks for Prostate Tissue Detection and Segmentation Birbiri, Ufuk Cem; Hamidinekoo, Azam; Grall, Amelie; Malcolm, Paul; Zwiggelaar, Reyer (2020-09-01) The manual delineation of region of interest (RoI) in 3D magnetic resonance imaging (MRI) of the prostate is time-consuming and subjective. Correct identification of prostate tissue is helpful to define a precise RoI to be used in CAD systems in clinical practice during diagnostic imaging, radiotherapy and monitoring the progress of disease. Conditional GAN (cGAN), cycleGAN and U-Net models and their performances were studied for the detection and segmentation of prostate tissue in 3D multi-parametric MRI s...
Impact of Iontophoresis and PACK-CXL Corneal Concentrations of Antifungals in an In Vivo Model KALKANCI, AYŞE; Yesilirmak, Nilufer; Ozdemir, Huseyin Baran; Unal, Elif Ayca; Erdogan, Merve; Şeker, Tamay; Tum, Atakan Emre; Karakus, Ahmet Kamil; Hizel, Kenan; Bilgihan, Kamil (Ovid Technologies (Wolters Kluwer Health), 2018-11-01) Purpose: To investigate voriconazole (VRZ) penetration and fungal load in the cornea after applying VRZ therapy with various treatment combinations in a fungal keratitis model. Methods: Fifty-four eyes of 27 young albino rabbits were provided for this experimental study. Twelve corneas were inoculated with Candida albicans, 12 corneas were inoculated with Fusarium solani, and 6 eyes were selected as controls. Infected corneas received various treatment combinations including VRZ 1% drop therapy alone, VRZ 1...
Comparison of methods for prediction of prostate cancer in Turkish men with PSA levels of 0-10 ng/mL GÜLKESEN, KEMAL HAKAN; KÖKSAL, İSMAİL TÜRKER; BİLGE, UĞUR; Saka, O. (2010-07-01) Purpose: Several concepts to improve the diagnostic accuracy of prostate specific antigen (PSA) for prediction of prostate cancer have been studied. The aim of this study was to examine and compare the methods used for improving the diagnostic accuracy of PSA in a country with low incidence of prostate cancer
The Effects of Local and Systemic Growth Hormone Treatment on Germ Cell Population and Fertility in an Experimental Unilateral Testicular Torsion and Orchiectomy Model ATEŞ, UFUK; Gollu, Gulnur; Bingol-Kologlu, Meltem; BİLLUR, DENİZ; Kucuk, Gonul; Oruklu, Nihan; Bagriacik, Umit; Hasırcı, Nesrin; DİNDAR, HÜSEYİN (2015-12-01) Purpose: We evaluated the effects of local and systemic growth hormone on the germ cell population of the contralateral testes of pubertal rats subjected to unilateral testicular torsion and orchiectomy 24 hours later.
