Öğe Comparison of semen profile and frequency of chromosome aneuploidies in sperm nuclei of patients with varicocele before and after varicocelectomy(WILEY, 2009) Acar, H.; Kilinc, M.; Guven, S.; Yurdakul, T.; Celik, R.Semen profile and meiotic segregation products are important for assessing aneuploidy risk and risk of resulting infertility. To determine the effect of varicocelectomy on semen profile and aneuploidy frequency, we investigated semen profile and aneuploidy frequency of selected chromosomes in patients with varicocele before and after varicocelectomy. Chromosomal aneuploidy for selected chromosomes was evaluated using chromosome-specific DNA fluorescence in situ hybridisation (FISH) probes. There was a significant difference in the level of normal sperm morphology before and after varicocelectomy (P > 0.007). There were no significant differences in aneuploidy frequency of chromosomes 1, 16, 17 and 18 in sperm nuclei obtained from patients before varicocelectomy compared with 6-7 months after varicocelectomy (P > 0.05), although FISH analysis with chromosomes 17 and 18 combination showed a higher aneuploidy frequency before varicocelectomy than after varicocelectomy (7.81 +/- 9.67 versus 4.03 +/- 1.46 respectively). In conclusion, varicocele seems to affect the semen profile but minimally affects aneuploidy frequency. Varicocelectomy demonstrates a repairing effect on the semen profile and contributes to a slight decrease in aneuploidy frequency in some but not all chromosomes.Öğe EFFECTS OF UROLOGY SPECIALISTS AND RESIDENTS OF DIFFERENT LEVELS OF EXPERIENCE TO PNL RESULTS(ELSEVIER SCIENCE BV, 2011) Guven, S.; Ozturk, A.; Gurbuz, R.; Goger, E.; Kaynar, M.; Ardic, M.; Kilinc, M.[Abstract not Available]Öğe Giant prostatic hyperplasia: Case report(SPRINGER, 2006) Yilmaz, K.; Istanbulluoglu, O.; Guven, S.; Kilinc, M.The giant hyperplasia of the prostate is extremely rare pathology of prostate gland. Here, we report the successful removal of the 9th heaviest prostate ever reported in the literature.Öğe Partial priapism secondary to tamsulosin: a case report and review of the literature(WILEY, 2009) Kilinc, M.; Piskin, M.; Guven, S.; Gurbuz, R.; Odev, K.; Kaynar, M.Partial priapism is also called partial segmental thrombosis of the corpus cavernosum. It is a rare pathology, and its aetiology, physiopathology and treatment are still not completely understood. To our knowledge, partial priapism due to alpha blockers has not been reported previously in the literature. In this study, a successfully treated case of partial priapism occurring after the usage of alpha blocker is presented and discussed in light of the related literature.Öğe TOTALLY TUBELESS PERCUTANEOUS NEPHROLITHOTOMY: IS IT SAFE AND EFFECTIVE IN PRESCHOOL CHILDREN? -- 2(MARY ANN LIEBERT INC, 2010) Guven, S.; Ozturk, A.; Kilinc, M.; Topbas, E.; Piskin, M.; Arslan, M.[Abstract not Available]
