    Long-Term Effect of Microsurgical Inguinal Varicocelectomy on Testicular Blood Flow
    Tarhan, S; Ucer, O; Sahin, MO; Gumus, B
    We aimed to investigate the long-term effect of microsurgical inguinal varicocelectomy on testicular blood flow using color Doppler sonography (CDS) in this observational study. A total of 30 patients clinically diagnosed with left varicocele who underwent a microsurgical inguinal varicocelectomy were examined 3 times with CDS for testicular blood flow parameters, first before, then 3 months after, and finally 6 months after the operation. CDS values of testicular blood flow (peak systolic velocity, end diastolic velocity, resistive index, and pulsatility index) were measured from testicular, capsular, and intratesticular arteries. We also evaluated preoperative and postoperative semen parameters. The mean values of blood flow velocities in the left testicular artery (peak systolic and end diastolic) increased and resistance indices (resistive and pulsatility) in the left capsular and intratesticular arteries decreased significantly after surgery (P < .05). No significant difference was detected between the preoperative and postoperative blood flow parameters in the right testicular, capsular, or intratesticular arteries (P < .05). In the semen analysis run 3 months after the operations, statistically significant increases were found in sperm concentration (P < .001), morphology percentage (P < .001), and total motile sperm concentration (P = .009). The increase in blood flow velocity in the testicular artery and the decrease in resistive and pulsatility indices in the capsular and intratesticular branches of the artery may be strong indicators of an increase in testicular arterial blood flow into the testicular tissue. Our data show that a significant improvement occurs in testicular blood supply and sperm parameters after microsurgical inguinal varicocelectomy.

    Sahin, MO; Sen, V; Eser, E; Koc, E; Gumus, U; Karakuzu, C; Ucer, O
    Introduction: We aimed to evaluate the effects of hyperbaric oxygen therapy (HBOT) on erectile function in patients who had no cavernosal or urethral injury by using International Index of Erectile Function (IIEF) questionnaire. Materials and Methods: The male patients who were treated by HBOT for several diseases between July 2017 and September 2017 were examined. All patients filled the IIEF questionnaire form before the first day and after the last day of HBOT and a questionnaire including demographic characteristics and medical history. The effects of demographic characteristics and risk factors on erectile function were evaluated, and the IIEF domain scores of patients in first day and last day of HBOT were compared. Results: Totally, 50 patients were included in the study between July 2017 and September 2017 and the mean age was 59.38 +/- 13.77. The mean post-HBOT IIEF-EF score of patients was significantly higher than the mean pre-HBOT IIEF-EF score of patients (15.74 +/- 10.52 vs. 19.50 +/- 10.91; p < 0.001). The mean post-HBOT IIEF scores of other domains including intercourse satisfaction, orgasmic function, sexual desire, and overall satisfaction were also significantly higher than pre-HBOT scores. Conclusions: HBOT may be a good alternative treatment or adjunctive treatment for erectile dysfunction. (C) 2018 S. Karger AG, Basel

    Effect of smoking cessation on sexual functions in men aged 30 to 60 years
    Sahin, MO; Sen, V; Gunduz, G; Ucer, O
    Purpose: We aimed to evaluate the effects of smoking cessation on the sexual functions in men aged 30 to 60 years. Materials and Methods: Male patients aged 30 to 60 years that presented to the smoking cessation polyclinic between July 2017 and December 2018 were prospectively included in the study. The amount of exposure to tobacco was evaluated in pack-year. The patients filled the International Index of Erectile Function (IIEF) form before the cessation and six months after cessation of smoking. Patients were subgrouped according to age, education level and packs/year of smoking and this groups were compared in terms of IIEF total and all of the IIEF domains. Results: The evaluations performed by grouping the patients according to age (30-39, 40-49 and 50-60 years) and education level (primary-middle school and high school-university) revealed that the total IIEF scores obtained after smoking cessation were significantly higher compared to the baseline scores in all groups (p=0.007 for the 30-39 years group and p<0.001 for the remaining groups). According to grouping by exposure to smoking (<= 25, 26-50, 51-75, 76-100 and 101 >= packs/year), the total IIEF scores significantly increased after smoking cessation in all groups except 101 >= packs/year (p=0.051 for the 101 >= group and p<0.001 for the remaining groups). Conclusions: Erectile function is directly proportional to the degree of exposure to smoking, and quitting smoking improves male sexual function in all age groups between 30-60 years of age regardless of pack-year and education level.

    Impact of previous SWL on ureterorenoscopy outcomes and optimal timing for ureterorenoscopy after SWL failure in proximal ureteral stones
    Irer, B; Sahin, MO; Erbatu, O; Yildiz, A; Ongun, S; Cinar, O; Cihan, A; Sahin, M; Sen, V; Ucer, O; Kizilay, F; Bozkurt, O
    Purpose We aimed to evaluate the impact of previous unsuccessful shock wave lithotripsy (SWL) therapy on ureterorenoscopy (URS) outcomes in proximal ureteral stones and to define whether there is any optimal timing for safe URS after SWL. Methods The patients who underwent URS for proximal ureteral stones between the years 2015 and 2018 in eight centers were included. Patients were divided into two groups according to previous SWL history; group 1 consisted of patients without SWL before URS for the stone [SWL (-)] and group 2 consisted of patients with a previous SWL for the stone [SWL (+)]. Demographics, operation outcomes and stone characteristics were compared between these two groups. Regarding the complication and success rates, optimal timing for URS after SWL for the stone was calculated with receiver operator characteristics curve analysis. Results Totally 638 patients were included (group 1: 466 patients and group 2: 172 patients). The operation and hospitalization times, rate of ureteral stenting and complications were significantly higher in group 2. Stone free status was similar between the groups. Optimal timing for URS after SWL was calculated as 16.5 days (AUC = 0.657, p = 0.012) with a sensitivity of 68% and specificity of 72%, regarding the complication rates. Complication rates were significantly higher in patients who were operated before 16.5 days (27.7% vs 6.5%, p < 0.001). Conclusions The optimal timing; 2-3 weeks delay of the URS procedure after unsuccessful SWL may decrease complication rates according to our results.

    Sen, V; Irer, B; Erbatu, O; Yildiz, A; Ongun, S; Cinar, O; Cihan, A; Sahin, M; Sahin, MO; Ucer, O; Kizilay, F; Bozkurt, O
    Introduction: We aimed to evaluate the predictive factors in a holistic manner for ureterorenoscopy (URS) outcomes in proximal ureteral stones by a multicenter study. Materials and Methods: The data of patients who underwent URS for proximal ureteral stones between the years 2015 and 2018 in eight centers were recorded retrospectively. Patients were divided into two groups according to URS success: Group 1 consisted of patients with successful URS, and Group 2 consisted of patients with unsuccessful URS. The two groups were compared in terms of risk factors, stone, and clinical characteristics of patients. Results: A total of 638 patients were included in the study. Group 1 consisted of 527 (82.6%) patients, and Group 2 consisted of 111 (17.4%) patients. In multivariate logistic analysis, the key risk factors for URS success was found to be age (OR = 0.980, 95% [CI] = 0.963-0.996, p = 0.018), stone area (OR = 0.993, 95% [CI] = 0.989-0.997, p = 0.002), and operation time (OR = 0.981, 95% [CI] = 0.968-0.994, p = 0.005). Conclusions: To make the treatment decision of proximal ureteral stones, it is necessary to examine several parameters including available equipment, stone, and patient characteristics. Physicians should keep these risk factors in mind in the decision of treatment options.

    Comparison of Efficacy and Complications of Holmium Laser and Pneumatic Lithotripters Used in the Ureterorenoscopic Treatment of Proximal Ureter Stones, a Multi-Center Study of Society of Urological Surgery Aegean Study Group
    Irer, B; Sen, V; Erbatu, O; Yildiz, A; Ongün, S; Çinar, Ö; Cihan, A; Sahin, M; Sahin, MO; Üçer, O; Kizilay, F; Bozkurt, O
    Objective:The aim of this study is to compare the efficacy and complications of holmium laser and pneumatic lithotripsy used in the ureterorenoscopic treatment of proximal ureteral stones. Materials and Methods: Data of 638 patients, who underwent ureterorenoscopy (URS) due to proximal ureteral stones in different centers, were obtained from patient files. The patients were divided into two groups according to the type of lithotripter used: group 1; laser lithotripter (n=324; 50.8%) and group 2; pneumatic lithotripter (n=314; 49.2%). URS was considered successful upon determination stone-free status with the imaging methods after treatment. The effectiveness and the complications of holmium:yttrium-aluminum-garnet laser and pneumatic lithotripsy were compared. Results: The total success rate of URS was 82.6% and the complication rate was 8.1%. The mean age of patients was similar between the groups; however, the body mass index values, stone surface area and stone Hounsfield unit were significantly higher in group 1. Although the mean operative time, complication rate and the mean length of hospital stay were similar between the groups; the URS success and postoperative ureteral J stent use rates were significantly higher in group 1 and the push-back rate was significantly higher in group 2. Conclusion: If laser lithotripsy is available in a clinic, we believe that it is better to use it as the first option in the treatment of proximal ureter stones. However, considering that it is not easy to access laser lithotripters due to their high cost in Turkey, pneumatic lithotripters may be an effective and inexpensive alternative that can also be safely used in these cases.

    Sen, V; Irer, B; Horsanali, MO; Sahin, MO; Egriboyun, S; Kizer, O; Öztürk, B; Sarikaya, E; Ongun, S; Üçer, O; Bozkurt, O; Demir, Ö
    Objective: This study aimed to present the impact of coronavirus disease-2019 pandemic on seeking treatment in patients with erectile dysfunction (ED) and compare the clinical characteristics, demographics, and laboratory analysis of patients with ED during and before the pandemic period. Materials and Methods: The clinical and demographic characteristics and laboratory analysis of patients with ED were compared between the time interval of March 9, 2020, to June 1, 2020, and the previous 3 months from the pandemics. The International Index of Erectile Function-5 questionnaire was used to assess ED and the results from two groups were compared. Results: A 76.4% decreased total number of outpatient clinics and a 70.9% decreased number of patients with ED was observed; however a significant increase was detected in the ratio of patients with ED to the total number of patients during the pandemic period (1.7% vs. 2.1%, p=0.008). The median age of patients was smaller in the pandemic period. Mild ED was significantly higher in the pandemic period and moderate ED was detected higher in the period before the pandemic. Conclusion: The admission rate of patients with ED has increased in the pandemic period. The patients presenting with ED during the pandemic period were younger, with milder ED symptoms.
