The Effect of Hyperbaric Oxygen Therapy on Erectile Functions: A Prospective Clinical Study
(S. Karger AG, 2018) Sahin M.O.; 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. © 2018 2018 S. Karger AG, Basel.

(John Wiley and Sons Inc., 2020) Sismanlar Eyuboglu T.; Dogru D.; Çakır E.; Cobanoglu N.; Pekcan S.; Cinel G.; Yalçın E.; Kiper N.; Sen V.; Selimoglu Sen H.; Ercan O.; Keskin O.; Bilgic Eltan S.; Alshadfan L.; Yazan H.; Altıntas D.U.; Sasihuseyinoglu A.S.; Sapan N.; Cekic S.; Cokugraş H.; Kılınc A.A.; Ramaslı Gursoy T.; Aslan A.T.; Bingol A.; Başaran A.E.; Ozdemir A.; Kose M.; Hangul M.; Emiralioglu N.; Tugcu G.; Yuksel H.; Yılmaz O.; Orhan F.; Gayretli Aydın Z.G.; Topal E.; Tamay Z.; Suleyman A.; Can D.; Bal C.M.; Caltepe G.; Ozcelik U.
Background: Pseudo-Bartter syndrome (PBS) is a rare complication of cystic fibrosis (CF) and there are limited data in the literature about it. We aimed to compare clinical features and accompanying findings of patients with PBS in a large patient population. Methods: The data were collected from the Cystic Fibrosis Registry of Turkey where 1170 CF patients were recorded in 2017. Clinical features, diagnostic test results, colonization status, complications, and genetic test results were compared in patients with and without PBS. Results: Totally 1170 patients were recorded into the registry in 2017 and 120 (10%) of them had PBS. The mean age of diagnosis and current age of patients were significantly younger and newborn screening positivity was lower in patients with PBS (P <.001). There were no differences between the groups in terms of colonization status, mean z-scores of weight, height, BMI, and mean FEV1 percentage. Types of genetic mutations did not differ between the two groups. Accompanying complications were more frequent in patients without PBS. Conclusion: PBS was detected as the most common complication in the registry. It could be due to warm weather conditions of our country. It is usually seen in younger ages regardless of mutation phenotype and it could be a clue for early diagnosis of CF. © 2020 Wiley Periodicals, Inc.
Impact of previous SWL on ureterorenoscopy outcomes and optimal timing for ureterorenoscopy after SWL failure in proximal ureteral stones
(Springer, 2020) Irer B.; Sahin M.O.; Erbatu O.; Yildiz A.; Ongun S.; Cinar O.; Cihan A.; 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. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
Predictive Factors of Ureterorenoscopy Outcomes in Proximal Ureteral Stones: A Multicenter Study of Aegean Study Group of the Society of Urological Surgery
(S. Karger AG, 2020) Sen V.; Irer B.; Erbatu O.; Yildiz A.; Ongun S.; Cinar O.; Cihan A.; Sahin M.O.; 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. © 2019 S. Karger AG, Basel.
Effect of smoking cessation on sexual functions in men aged 30 to 60 years
(Brazilian Society of Urology, 2020) Sahin M.O.; 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 packyear. 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 schooluniversity) 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. © 2020, Universidade Federal Rural do Rio de Janeiro (UFRRJ).
Geographical barriers to timely diagnosis of cystic fibrosis and anxiety level of parents during newborn screening in Turkey
(John Wiley and Sons Inc, 2021) Gokdemir Y.; Eyuboglu T.S.; Emiralioglu N.; Er B.; Sen V.; Pekcan S.; Ergenekon A.P.; Hizal M.G.; Eryilmaz S.; Kose M.; Hangul M.; Cakir E.; Cokugras H.; Kılınc A.A.; Sasıhuseyinoglu A.S.; Altintas D.U.; Gulen F.; Eski A.; Bingol A.; Ozdemir A.; Topal E.; Gursoy T.R.; Girit S.; Ay P.; Yılmaz O.
Background: Despite the availability of cystic fibrosis (CF) screening countrywide, diagnostic delay is still a crucial issue. The objectives of this study were to explore the stages of the NBS process, determine the risk factors associated with diagnostic delay and evaluate parent anxiety and experience throughout the process. Methods: This is a multicenter cross-sectional study. A questionnaire was completed by parents of newborns diagnosed with CF via NBS in 17 centers. Socio-demographic characteristics, parent knowledge and experiences related to NBS, sweat test availability in the region of residence, and time to the definitive CF diagnosis were assessed through this questionnaire. Parents' anxiety levels were evaluated through the State-Trait Anxiety Inventory scales 1 and 2. Delayed diagnosis (DD) was defined as a definite CF diagnosis beyond the 8th week of life. Predictors of delayed CF diagnosis were evaluated by univariate and multivariate analysis. Results: A total of 220 CF patients diagnosed via NBS were enrolled; 82 (37.3%) babies had DD. Multivariable analysis indicated that residence in the Southeast Anatolia region of Turkey (OR = 10.79, 95% CI = 2.37–49.2) was associated with a higher incidence of DD compared with other regions in Turkey. Of the total, 216 (98.1%) of the caregivers regarded the NBS program as useful and 180 (82%) reported high anxiety levels. Conclusion: The organization of newborn screening should take into account regional and socio-cultural characteristics to improve the early diagnosis of CF and also reduce the anxiety level of parents. © 2021 Wiley Periodicals LLC

Objective: To present a nation-wide analysis of the workload of urology departments in Turkey week-by-week during Covid-19 pandemic. Methodology: The centres participating in the study were divided into three groups as tertiary referral centres, state hospitals and private practice hospitals. The number of outpatients, inpatients, daily interventions and urological surgeries were recorded prospectively between 9-March-2020 and 31-May-2020. All these variables were recorded for the same time interval of 2019 as well. The weekly change of the workload of urology during pandemic period was evaluated, also the workload of urology and the distributions of certain urological surgeries were compared between the pandemic period and the same time interval of the year 2019. Results: A total of 51 centres participated in the study. The number of outpatients, inpatients, urological surgeries and daily interventions were found to be dramatically decreased by the 3rd week of pandemics in state hospitals and tertiary referral centres; however, the daily urological practice were similar in private practice hospitals throughout the pandemic period. When the workload of urology in pandemic period and the same time interval of the year 2019 were compared, a huge decrease was observed in all variables during pandemic period. However, temporary measures like ureteral stenting, nephrostomy placement and percutaneous cystostomy have been found to increase during Covid-19 pandemic compared with normal life. Conclusions: Covid-19 pandemic significantly affected the routine daily urological practice likewise other subspecialties and priority was given to emergent and non-deferrable surgeries by urologists in concordance with published clinical guidelines. © 2020 John Wiley & Sons Ltd

(Blackwell Publishing Ltd, 2021) Cinar O.; Tanidir Y.; Ozer S.; Cizmeci S.; Erbatu O.; Ozdemir T.; Girgin R.; Ongun S.; Ucer O.; Kizilay F.; Sen V.; Irer B.; Bozkurt O.
Aims of the study: To investigate the effect of mirabegron 50 mg/daily for JJ stent-related symptoms after ureteroscopic stone surgery. Methods: Medical records of 145 patients who were given a single daily oral dose of 50 mg of mirabegron for relieving stent-related symptoms were retrospectively analysed. Demographic and clinical data and stone parameters were recorded. All participants completed the Turkish version of the Ureter Symptom Score Questionnaire (USSQ-T) on the postoperative 7th day, and again after at least 3 weeks, before JJ stent removal. The severity of stent-related symptoms was statistically compared before and after the mirabegron treatment. Results: The mean urinary symptoms score decreased significantly from 30.87 ± 9.43 to 22.61 ± 6.78 (P <.0001), mean body pain score decreased significantly from 21.82 ± 11.22 to 14.03 ± 7.52 (P <.0001), mean work performance score decreased from 10.50 ± 8.61 to 7.02 ± 6.51 (P <.0001) and mean general health score decreased significantly from 15.43 ± 6.50 to 11.12 ± 3.70 (P <.0001). The mean sexual matters score significantly decreased from 3.88 ± 3.40 to 2.48 ± 2.03 (P <.0001), the additional problem score decreased from 9.31 ± 4.61 to 6.51 ± 2.83 (P <.0001) and the overall quality of life (QoL) score decreased from 5.18 ± 1.94 to 4.23 ± 1.71 after mirabegron use (P <.0001). Conclusion: Daily use of 50 g of mirabegron significantly improved stent-related symptoms, sexual matters and quality of life. © 2020 John Wiley & Sons Ltd

(John Wiley and Sons Inc, 2021) Bozkurt O.; Irer B.; Kizilay F.; Erbatu O.; Sen V.; Cinar O.; Ongun S.; Cihan A.; Ozdemir T.; Tasdemir D.; Ucer O.
Objective: To identify the pathophysiological mechanisms of nocturia and the correlation of these mechanisms with nocturia severity. Methodology: After approval by the local ethics committee, all patients with nocturia (≥1 nocturnal void/night) were included and filled the Overactive Bladder questionnaire, Nocturia Quality of Life, Incontinence Questionnaire - Male Lower Urinary Tract Symptoms (male), International Consultation on Incontinence Questionnaire - Female Lower Urinary Tract Symptoms (female) and 3-day frequency-volume chart. Patients were divided into three groups according to the severity of nocturia: group 1 consisted of patients with mild (1-2 voids/night), group 2 with moderate (3-4 voids/night) and group 3 with severe nocturia (>4 voids/night). Comparative analysis was performed between groups, and P <.05 was deemed as statistically significant. Results: About 68.1%, 64.1% and 8.7% of the patients had nocturnal polyuria (NP), reduced bladder capacity and global polyuria, respectively. 42.7% of the patients had mixed nocturia. 6.1% of the patients did not comply with the aforementioned subtypes and defined as isolated nocturia. Regarding the severity of nocturia, 155 (41%) patients had mild, 167 (45%) patients had moderate and 57 (15%) patients had severe nocturia. Increased nocturia severity was related with decreased quality of life; higher age, urinary tract symptom scores, nocturnal urine volume, evening fluid consumption and beta-blocker medication rates. Increased nocturia severity was also associated with higher NP, global polyuria and reduced bladder capacity rates. Conclusions: Nocturia mechanisms may vary between mild and moderate to severe nocturia groups according to the present study. Nocturia grading with identification of subtypes may help for better standardisation of the diagnostic and treatment approaches as well as for the design of future clinical trials. © 2020 John Wiley & Sons Ltd

Background: Cystic fibrosis (CF) registries play an essential role in improving disease outcomes of people with CF. This study aimed to evaluate the association of newly established CF registry system in Turkey on follow-up, clinical, growth, treatment, and complications of people with this disease. Methods: Age at diagnosis, current age, sex, z-scores of weight, height and body mass index (BMI), neonatal screening results, pulmonary function tests, history of meconium ileus, medications, presence of microorganisms, and follow-up were evaluated and compared to data of people with CF represented in both 2017 and 2019 registry data. Results: There were 1170 people with CF in 2017 and 1637 in 2019 CF registry. Eight hundred and fourteen people were registered in both 2017 and 2019 of whom z-scores of heights and BMI were significantly higher in 2019 (p = 0.002, p =0.039, respectively). Inhaled hypertonic saline, bronchodilator, and azithromycin usages were significantly higher in 2019 (p =0.001, p = 0.001, p = 0.003, respectively). The percent predicted of forced expiratory volume in 1 sec and forced vital capacity were similar in 2017 and 2019 (88% and 89.5%, p = 0.248 and 84.5% and 87%, p =0.332, respectively). Liver diseases and osteoporosis were significantly higher, and pseudo-Bartter syndrome (PBS) was significantly lower in 2019 (p = 0.011, p = 0.001, p = 0.001, respectively). Conclusions: The z-scores of height and BMI were higher, the use of medications that protect and improve lung functions was higher and incidence of PBS was lower in 2019. It was predicted that registry system increased the care of people with CF regarding their follow-up. The widespread use of national CF registry system across the country may be beneficial for the follow-up of people with CF. © 2022 Wiley Periodicals LLC.

(John Wiley and Sons Inc, 2022) Ramasli Gursoy T.; Aslan A.T.; Asfuroglu P.; Sismanlar Eyuboglu T.; Cakir E.; Cobanoglu N.; Pekcan S.; Cinel G.; Dogru D.; Ozcelik U.; Yalcin E.; Sen V.; Ercan O.; Kilinc A.A.; Yazan H.; Altintas D.U.; Kartal Ozturk G.; Bingol A.; Sapan N.; Celebioglu E.; Tugcu G.D.; Ozdemir A.; Harmanci K.; Kose M.; Emiralioglu N.; Tamay Z.; Yuksel H.; Ozcan G.; Topal E.; Can D.; Korkmaz Ekren P.; Caltepe G.; Kilic M.; Ozdogan S.
Background: Cystic fibrosis (CF) is a lethal recessive genetic disease caused by loss of function associated with mutations in the CF trans-membrane conductance regulator. It is highly prevalent (approximately 1 in 3,500) in Caucasians. The aim of this study was to compare demographic and clinical features, diagnostic tests, treatments, and complications of patients with CF whose newborn screening (NBS) with twice-repeated immune reactive trypsinogen testing was positive, normal, and not performed. Methods: In this study, 359 of all 1,488 CF patients recorded in the CF Registry of Turkey in 2018, who had been born through the process of NBS, were evaluated. Demographic and clinical features were compared in patients diagnosed with positive NBS (Group 1), normal (Group 2), or without NBS (Group 3). Results: In Group 1, there were 299 patients, in Group 2, there were 40 patients, and in Group 3, there were 20 patients. Among all patients, the median age at diagnosis was 0.17 years. The median age at diagnosis was higher in Groups 2 and 3 than in Group 1 (P = 0.001). Fecal elastase results were higher in Group 2 (P = 0.033). The weight z-score was lower and chronic Staphylococcus aureus infection was more common in Group 3 (P = 0.017, P = 0.004, respectively). Conclusions: Frequency of growth retardation and chronic S. aureus infection can be reduced with an early diagnosis using NBS. In the presence of clinical suspicion in patients with normal NBS, further analyses such as genetic testing should be performed, especially to prevent missing patients with severe mutations. © 2021 Japan Pediatric Society.
