    INFLUENCE OF THE ERECTILE DYSFUNCTION ON QUALITY OF LIFE ACCOMPANYING DIABETES MELLITUS: A LONGITUDINAL, CONTROLLED STUDY
    Okur, M; Gümüs, B; Üçer, O; Karatas, TC; Özmen, E; Büyüksu, C
    Introduction: Erectile dysfunction (ED) is one of the most common complications of Diabetes Mellitus (DM) in males and has a negative impact on the quality of life (QoL). The number of studies related with this subject is limited in the literature. QoL was evaluated and compared in diabetic patients with and without ED. Materials and Methods: Patients with ED who applied to our outpatient clinics (Celal Bayar University, Medical Faculty, Department of Urology) were included in the study. We interviewed 82 patients with DM+ED, 85 patients with ED and 65 normal (control) male subjects. All men (study and control groups) were asked to fill the IIEF (International Index of Erectile Function), CES-D (Center of Epidemiological StudiesDepression), BAI (Beck Anxiety Inventory), PIED (Pyschological Impact of Erectile Dysfunction) forms. Sildenafil citrate was administered as a medical treatment. Same forms were asked to be filled again in the 3th, 6th, 9th months of the therapy. Results: We observed that QoL of the patients with DM+ED and ED were affected negatively. ED was worse in the DM group compared to others. Significant improvements were detected in both QoL and ED in 3th and 6th months of the therapy. Conclusion: Our data show that treatment of ED significantly improves QoL in the patients with DM therefore, presence of ED has to be assessed in the patients with DM.

    Comparison of audiovisual sexual stimulation test with nocturnal penile tumescence test in the evaluation of erectile dysfunction by using RigiScan
    Incirci, M; Üçer, O; Karatas, TC; Atesçi, YZ; Gümüs, B
    Objective: Nocturnal penile tumescence (NPT) test is a time-consuming, cumbersome, and relatively expensive method which is used for the diagnosis of erectile dysfunction (ED). The aims of the study were to clarify the relationship between erotic and nocturnal erections and to evaluate the diagnostic efficacy of the audiovisual sexual stimulation (AVSS) test with and without medication. Materials and methods: A total of 30 patients with ED were examined. Each patient filled in an International Index of Erectile Function-5 (IIEF-5) questionnaire. AVSS and NPT tests were performed using the RigiScan Plus. AVSS test was performed with and without medication (sildenafil citrate 50 mg). Patients were divided into two groups (psychogenic and organic groups) according to NPT and AVSS test results. Results: The mean age of the patients was 46.4 (23-69) years and IIEF-5 score was 10.8 +/- 4.5. Positive AVSS test was found in 18 (85.7%) of the 21 patients with positive NPT test. Negative AVSS test was found in 7 (77, 8%) of the 9 patients with negative NPT test. The specificity of AVSS test was 85.7% and sensitivity was 77.8% for the psychogenic groups. The overall accuracy rate was 83.3%. Conclusion: The NPT test is more expensive, cumbersome, and discomfortable than the AVSS test. Although efficiency of both tests is similar, the AVSS test seems more advantageous. We suggest that the AVSS test without medication should be performed as the first step in the diagnosis of the patients with ED. In patients with negative test result, the AVSS test with medication should be performed as the second step diagnostic method.

    Does Late-Onset Hypogonadism Occur by Aging? The Evaluation of IIEF, Ams-Q and Biochemical Parameters
    Üçer, O; Gümüs, B; Okur, M; Karatas, TC; Büyüksu, C
    Objective: The aim of this study is to investigate whether biochemical (hormonal) hypogonadism occurs by aging and whether ANIS-Q(Aging Male Symptoms-Questionnaire) and IIEF (International Index of Erectile Function) forms are adequate in order to evaluate its presence in case it occurs. Material and Methods: A total of 182 males who applied to the outpatient clinics of Urology Department and whose ages were between 45-90 years were included in the study. Those who had diabetes mellitus, hypertension, coronary artery disease, dyslipidemia, any psychiatric disorder and any malignancy were excluded. The patients were classified into three groups (Group 1; 45-54, Group 2; 55-64 and Group 3; over 65 years). All participants were asked to complete IIEF and AMS-Q forms and serum levels of total testosterone, free testosterone, LH, DHEA-S, SHBG and prolactin were measured. Results: Total testosterone and prolactin levels did not change with aging. Although free testosterone, bio-available testosterone and DHEA-S levels decreased with age, it was detected that LH and SHBG levels were increased. While IIEF scores decreased with age, however AMS-Q scores did not change. When subgroups of AMS-Q were taken into consideration, sexual scores increased, and a decrease in somatic and psychological scores was detected. There was a strong relationship between IIEF-EF (erectile function) and AMS-Sexual forms, Conclusion: All of the data indicate that secondary hypogonadism occurs by aging and consequent symptoms (especially sexual ones) can be evaluated with IIEF and AMS-Sexual forms.

    Testicular sperm retrieval method
    Gümüs, BH; Atesci, YZ; Ucer, O; Karatas, TC; Buyuksu, C; Nese, N; Kandiloglu, AR
    This research was conducted to evaluate the effects of a transverse vs. longitudinal incision for testicular sperm retrieval. Rats were divided into 4 groups: I: control, II: sham operation, III: longitudinal incision TSRM, IV: transverse incision TSRM. Group II (sham operation) had a dissection of left testis/spermatic cord, then closure of wound. Group III underwent dissection of left testis, then a longitudinal incision (15 mm long) of testis, which was fully opened then closed again and sutured with 5-0 Vicryl (R) sutures. Group IV underwent dissection of the left testis, opening of the testis with a transverse incision, then closure with 5-0 Vicryl (R). The seminiferous tubule diameter was 0.118-0.224 mm in all groups. inflammation and abscess formation occurred in one testis each in the sham and longitudinal incision groups, and in two testes in the transverse incision group. There were no differences in histopathology or scoring between the longitudinal and the transverse incision.
