Publication Relationship between testicular histopathology and the success of testicular sperm extraction in patients with non-mosaic Klinefelter syndrome(2021-01-01T00:00:00Z) Yucel, Cem; Keskin, Mehmet Zeynel; Kose, Can; Kucuk, Ulku; Ilbey, YUSUF ÖZLEM; Kozacioglu, Zafer; İLBEY, YUSUF ÖZLEMObjective: To investigate the effect of testicular histopathology on the success of microscopic testicular sperm extraction (mTESE) and the factors that could predict the success of mTESE in patients with non-mosaic Klinefelter syndrome (KS).Publication Comparison of intraperitoneal and intratesticular ozone therapy for the treatment of testicular ischemia- reperfusion injury in rats(2017-01-01T00:00:00Z) Mete, Fatih; Tarhan, Huseyin; Celik, Orcun; Akarken, Ilker; Vural, Kamil; Ekin, Rahmi Gokhan; Aydemir, Isil; Ilbey, YUSUF ÖZLEM; İLBEY, YUSUF ÖZLEMWe compare the efficacy of intratesticular ozone therapy with intraperitoneal ozone therapy in an experimental rat model. For this purpose, 24 rats were divided into four groups including sham-operated, torsion/detorsion, torsion/detorsion plus intraperitoneal ozone (O-P), and torsion/detorsion plus intratesticular ozone (O-IT). The O-IP ozone group received a 4 mg kg(-1) intraperitoneal injection of ozone, and the O-IT group received the same injection epididymally. At 4 h after detorsion, the rats were sacrificed and orchiectomy materials were assessed histopathologically. Spermatogenesis in the seminiferous tubules and damage to the Sertoli cells were histopathologically evaluated in the testes using the Johnsen scoring system. i-NOS and e-NOS activities in the testis tissue were also evaluated. Torsion-detorsion caused a decreased Johnsen score and increased apoptosis of spermatogonial and Sertoli cells. Ozone injection prevented increases in Johnsen score and i-NOS level. e-NOS level of the O-IP group was significantly lower than that of the O-IP group, and i-NOS level of the O-IT group was significantly lower than that of the O-IP group. Local ozone therapy is more effective than systemic ozone therapy at improving IRI-related testicular torsion. Our study is the first to show that the efficacy of intratesticular implementation of ozone therapy is higher than that of intraperitoneal ozone therapy.Publication 120-W GreenLight Laser Photoselective Vaporization of Prostate for Benign Prostatic Hyperplasia: Midterm Outcomes(2011-07-01T00:00:00Z) Tasci, Ali Ihsan; İLBEY, YUSUF ÖZLEM; Luleci, Huseyin; Cicekler, Olcay; Sahin, Selcuk; ÇEVİK, CEM; Tugcu, Volkan; İLBEY, YUSUF ÖZLEMOBJECTIVES To evaluate the safety and efficacy of 120-W high-performance system (HPS) laser photoselective vaporization of the prostate (PVP) in the treatment of patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia.Publication Our percutaneous nephrolitotomy experience in patients with horseshoe kidney(2015-01-01T00:00:00Z) Suelozgen, Tufan; Isoglu, Cemal Selcuk; Turk, Hakan; Yoldas, Mehmet; Ilbey, Ozlem Yusuf; Zorlu, Ferruh; İLBEY, YUSUF ÖZLEMObjectives: Horseshoe kidney is the most common renal congenital fusion anomaly. Kidney stone formation is more common in horseshoe kidneys and some of them requires surgical procedure. So we want to evaluate the results of PNL in patients with horseshoe kidney anomaly.Publication The effect of hydronephrosis grade on stone-free rate in retrograde intrarenal stone surgery with flexible ureterorenoscopy.(2021-04-15T00:00:00Z) Ergani, Batuhan; Ozbilen, Mert Hamza; Yalcın, Mehmet Yigit; Boyacıoglu, Hayal; Ilbey, YUSUF ÖZLEM; İLBEY, YUSUF ÖZLEMPublication Comparison of penile prosthesis types- complications: A retrospective analysis of single center(2020-12-01T00:00:00Z) Kisa, Erdem; Keskin, Mehmet Zeynel; Yucel, Cem; Ucar, Murat; Yalbuzdag, Okan; Ilbey, YUSUF ÖZLEM; İLBEY, YUSUF ÖZLEMObjectives: The aim of this study was to compare clinical outcomes and complication rates associated with semirigid (malleable) and inflatable penile prostheses (PPs) and investigate the factors that influence these complications.Publication Malignant mesothelioma of tunica vaginalis: Two extremely rare case reports(2021-06-01T00:00:00Z) Karabacakoglu, Burak; Kisa, Erdem; Ozbilen, Mert Hamza; Karademir, Baris; Yardim, Serdar; Celik, Orcun; Suelozgen, Tufan; Ilbey, YUSUF ÖZLEM; İLBEY, YUSUF ÖZLEMIntroduction: Malignant mesothelioma (MM) of tunica vaginalis is a very rare tumor and it has a poor prognosis. It is not easy to diagnose the disease preoperatively because there is a lack of comprehensive studies and information about the disease. We would like to present our two cases with severe scrotal edema and hydrocele, which were debrided perioperatively due to scrotal necrosis, followed by radical inguinal orchiectomy and subsequently diagnosed as MM of tunica vaginalis.Publication Prostatic adenocarcinoma with initial metastatic spread to the mandible(2015-09-01T00:00:00Z) Cakmak, Ozgur; Tarhan, Huseyin; Kucuk, Ulku; Ilbey, YUSUF ÖZLEM; İLBEY, YUSUF ÖZLEMProstate cancer is one of the commonest types of malignancy in males. Although prostate cancer has a propensity to metastasize to the bone, metastasis to the mandible is rare. Because of their uncommon incidence, the diagnosis of mandibular metastasis, especially those originating from the prostate, may represent a challenge both for urologists and dentists. Here we present a case of prostatic adenocarcinoma with initial metastatic spread to the mandible.Publication The effect of regular exercise on penile nitric oxide synthase expression in rats(2010-08-01T00:00:00Z) Ozbek, Emin; Tasci, Ali Ihsan; İLBEY, YUSUF ÖZLEM; Simsek, Abdulmuttalip; Somay, Adnan; METİN, Gökhan; İLBEY, YUSUF ÖZLEMP>Erectile dysfunction (ED) is a major public health problem that seriously affects the quality of life of patients and their partners and its prevalence increases significantly with ageing. In this study, we tested the hypothesis that age-associated decrease in penile endothelial (eNOS) and neuronal nitric oxide synthase (nNOS) activity in aged rats may be increased by regular exercise. A total of 28 young (4 m) and aged (24 m) male rats were divided into four equal groups: group 1 - young control; group 2 - young trained; group 3 - old control and group 4 - old trained group. Groups 2 and 4 rats were trained to swim for 30 min a day and 5 days a week, which lasted 8 weeks. At the end of 8 weeks, rats were sacrificed and penile tissues evaluated for eNOS and nNOS activities. eNOS and nNOS activities were evaluated by immunohistochemistry in paraffinized penile tissues and results assessed semiquantitatively. Results also were compared with healthy age-matched and adult (4 m) controls. Serum level of testosterone (T) was determined using ELISA kits (Beckman Coulter, Fullerton, CA, USA). In penile tissues of aged control rats, eNOS and nNOS staining were weakly positive; however in trained groups, eNOS and nNOS immunoreactivity were increased. In young control group, eNOS and nNOS activities were more intense than aged control. eNOS and nNOS activities were higher in adult trained group than control. Serum T concentrations were significantly higher in young and aged trained group than in control groups. We can suggest that regular exercise upregulates eNOS and nNOS expressions in the aged and young rat penis. Regular exercise may improve penile erection by increasing penile neurotransmitter in both young and aged rats.Publication Pyrrolidine dithiocarbamate treatment prevents ethylene glycol-induced urolithiasis through inhibition of NF-kappaB and p38-MAPK signaling pathways in rat kidney.(2010-06-01T00:00:00Z) Ilbey, YUSUF ÖZLEM; Ozbek, Emin; Simşek, Abdulmuttalip; Cekmen, Mustafa; Somay, Adnan; Tasci, Ali Ihsan; İLBEY, YUSUF ÖZLEM
