    (Taylor and Francis Ltd., 2022) Özman, Oktay; Başataç, Cem; Akgül, Hacı Murat; Çınar, Önder; Sancak, Eyüp Burak; Özden, Sami Berk
    Introduction: The Modified Seoul National University Renal Stone Complexity Score (S-ReSC) is a simple model based solely on stone location regardless of stone burden. The aims of this study were to validate S-ReSC for outcomes and complications of retrograde intrarenal surgery (RIRS) and to evaluate its predictive power against the stone burden. Material and methods: Data of 1007 patients with kidney stones who had undergone RIRS were collected from our RIRSearch database. Linear-by-linear association, logistic regression, ANOVA/post hoc analysis and ROC curve (with Hanley and McNeil’s test) were used for evaluation. The main outcomes were stone-free status and complications of RIRS. Results: The overall stone-free rate was 76.8% (773/1007). Higher S-ReSC scores were related to lower stone-free rates and higher total, perioperative and postoperative complication rates (p<.001, p<.001, p=.008 and p<.001, respectively). S-ReSC score (p=.02) and stone burden (p<.001) were independent predictors of stone-free status. But stone burden (AUC = 0.718) had a more powerful discriminating ability than the S-ReSC score (AUC = 0.618). Conclusions: The S-ReSC score is able to predict not only stone-free status but also complications of RIRS. Although this location-only based scoring system has a fair discriminative ability, stone burden is a more powerful predictor of stone-free status after RIRS. An ideal scoring system aiming to predict outcomes of RIRS must include stone burden as a parameter. © 2022 Society of Medical Innovation and Technology.

    (Canadian Urological Association, 2016) Sancak, Eyüp Burak; Oğuz, Sevilay; Akbulut, Tuğba; Uludağ, Ayşegül; Akbaş, Alpaslan; Kurt, Ömer; Akbulut, Mehmet Fatih
    Introduction: We sought to evaluate the association of female sexual dysfunction (FSD) with androgenetic alopecia (AGA) and metabolic syndrome (MetS) in premenopausal women. Methods: From December 2013 to June 2015, we performed a case-control, prospective study of 115 patients with AGA and 97 age-matched control patients without AGA from among premenopausal women who visited dermatology clinics of the two reference hospitals. Comprehensive history, anthropometric measurements, and questionnaire administration were performed for each of the total of 212 women. The Female Sexual Function Index (FSFI) was used to assess the key dimensions of female sexual function. AGA was assessed and graded by an experienced dermatologist according to Ludwig's classification. The MetS assessment was made according to the NCEP-ATP III criteria. Results: In univariate analysis, age, weight, waist circumference, hip circumference, waist-to-hip ratio, body mass index (BMI), AGA, MetS, cardiovascular event, marital status, hypertension, high fasting plasma glucose, high triglyceride, large waist, total testosterone, and free testosterone were associated with presence of FSD. In logistic regression analysis, age (odds ratio [OR] 1.21, 95% confidence interval [CI] 1.13. 1.30; p<0.001), AGA (OR 3.42, 95% CI 1.31. 8.94; p= 0.017), MetS (OR 5.39, 95% CI 1.34. 21.62; p= 0.012), and free testosterone (OR 0.18, 95% CI 0.09. 0.37; p< 0.001) were independently associated with FSD. Conclusions: Our study suggests that age, AGA, MetS, and free testosterone may have strong impact on sexual function in premenopausal women. Further studies with population-based and longitudinal design should be conducted to confirm this finding.

    Is it only a sleeping disorder or more? Restless legs syndrome and erectile function
    (Taylor & Francis Ltd, 2016) Kurt, Ömer; Yazıcı, Cenk Murat; Alp, Recep; Sancak, Eyüp Burak; Topçu, Birol
    Objective: Sexual dysfunction and restless legs syndrome (RLS) have similar pathophysiological properties. This study evaluated the presence of erectile dysfunction (ED) and premature ejaculation (PE) in patients with RLS. Materials and methods: Fifty patients in the RLS group and 50 in the control group were included in the study. The International Restless Legs Syndrome Study Group rating scale, the five-item International Index of Erectile Function and the Premature Ejaculation Diagnostic Tool were used to define the RLS and erectile function of both the study and control groups. A stopwatch technique was used to evaluate the intravaginal ejaculatory latency time of patients in the study. Results: The mean age of patients in the RLS and control groups was 53.5 +/- 9.9 and 53.2 +/- 8.8 years, respectively (p = 0.527). None of the patients in either group had diabetes mellitus. There was no difference between the groups in terms of history of hypertension, body mass index and total testosterone level. There were 27 patients (54%) in the RLS group and 17 patients (34%) in the control group with PE (p = 0.008). There were 26 patients (52%) with ED in the RLS group and 17 (34%) in the control group (p = 0.069). The prevalence of moderate and severe ED was significantly higher in the RLS group (p = 0.045). Conclusions: PE was more prevalent in RLS than in control patients. On the other hand, the rate of ED did not differ between the groups. In addition to receiving a neurological evaluation, RLS patients must be evaluated for sexual function.

    Prediction of Possible Factors That Affect Stone-Free Rate of Retrograde Intrarenal Surgery; a Multicenter Study
    (2020) Özman, Oktay; Başataç, Cem; Akpınar, Haluk; Akgül, Murat; Yazıcı, Cenk Murat; Çınar, Önder; Sancak, Eyüp Burak
    Aim: The aim of the study was to evaluate possible factors predicting stone-free status at retrograde intrarenal surgery for renal stones.Materials and Methods: A retrospective multicenter study was performed using data from 513 patients treated between February 2016 and January 2020 at four referral centers in Turkey. The patients were divided into two groups whether they had no residual stone over 3mm (Group 1) or had residual stones (Group 2). Pre and peroperative parameters were compared in both groups (Table 1). Univariateand multivariate analyzes were performed to identify any factors affecting the stone-free rate (Table 2).Results: Overall stone-free rate was 88.5% (454/513). Lower calyx stones and multipl stones were significantly higher in Group 2 (p=0.006, p=0.02, respectively). Also access sheathless procedure rate was significantly higher and the basket catheter useage rate was significantly lower in Group 2 (p=0.04, p<0.001, respectively) (Table 1). Multiple stone presence and basket catheter usage during the procedure were found as independent factors to predict the stone-free status of Retrograde Intrarenal Surgery according to the results of logistic regression analysis (95%CI 3.3577-0.9999; H-L p= 0.05 and 95%CI 0.4442-0.1290; H-L p< 0.001, respectively) (Table 2).Conclusion: The presence of multiple stones in preoperative imaging and the use of basket catheters peroperatively are independent factors predicting stone-free status in Retrograde Intrarenal Surgery. The presence of multiple stones increases the probability of residual stones after the procedure, while the use of basket catheters is to reduce this possibility.

    Recent scoring systems predicting stone-free status after retrograde intrarenal surgery; a systematic review and meta-analysis
    (Polish Urological Assoc, 2022) Özman, Oktay; Akgül, Hacı Murat; Başataç, Cem; Sancak, Eyüp Burak; Çınar, Önder; Çakır, Hakan; Yazıcı, Cenk Murat
    Introduction Several scoring systems and nomograms have been developed to predict the success of retrograde intrarenal surgery. But no meta-analysis for the performance of scoring systems has yet been performed. The aim of this study was to compare predictive ability of recent scoring systems for stone-free rate of retrograde intrarenal surgery. Materials and methods PubMed and Web of Science databases were searched systematically between April and May 2021. The scoring systems which were validated externally or studied at least by two different researcher groups were selected for further analysis. Of 59 records, 14 studies met the inclusion criteria (n = 4137). Area under curve (AUC) values of selected scoring systems were pooled in random or fixed effects. Thertest was used to quantify heterogeneity. Results Eight, 5, 8, 4 and 3 studies included in meta-analyses for the modified Seoul National University Renal Stone Complexity Score (S-ReSC), R.I.R.S., Resorlu-Unsal Score (RUS), S.T.O.N.E., and Ito's Nomogram, respectively. We found pooled AUC values 0.709 (95% CI 0.670-0.748), 0.704 (95% CI 0.668-0.739), 0.669 (95% CI 0.646 to 0.692), and 0.771 (95% CI 0.724 to 0.818), for first four of them, respectively. Heterogeneity was very high to pool AUC values for Ito's nomogram. Conclusions Although S.T.O.N.E. score showed higer pooled AUC value, this systematic review and meta-analysis has not revealed superiority of any scoring system. High heterogeneity between studies and dependencies between scoring systems make it difficult to design a comparative statistical model to generalize the findings. Also, limitations aside, neither scoring system has demonstrated good predictive/discriminative performance.

    The effectiveness of biofeedback therapy in children with monosymptomatic enuresis resistant to desmopressin treatment
    (Aves, 2016) Sancak, Eyüp Burak; Akbaş, Alpaslan; Kurt, Ömer; Alan, Cabir; Ersay, Ahmet Reşit
    Objective: To investigate the effect of biofeedback therapy on children with desmopressin-resistant primary monosymptomatic enuresis (MsE). Material and methods: The study comprised both retrospective and prospective sections. A total of 262 medical files of patients who were diagnosed as enuresis between November 2012 and January 2015 were retrospectively screened. Patients with neuropathic bladder, daytime voiding problems, anatomical pathology and enuresis-related diseases were excluded from the study. The demographic data and family characteristics of 29 children with desmopressin-resistant primary MsE were recorded. After biofeedback treatment patients whose frequency of enuretic episodes decrease by more than 50% were included in the successful biofeedback treatment group (SBTG), while other patients were categorized in the unsuccessful biofeedback treatment group (USGBT). The outcomes of uroflowmetry, voided volume, postvoiding residue (PVR) and total bladder volume/age-adjusted normal bladder capacity (TBV/NBC) were recorded before and at the sixth month of the treatment. Results: The mean age of 29 patients included in the study was 9.14 +/- 3.07 (6-15) years. Of patients, 16 were male (55.2%) and 13 were female (44.8%). Before biofeedback treatment the frequency of enuresis was 25.1 +/- 5.76 days/month, while after treatment this was calculated as 8.52 +/- 10.07 days/month. After treatment 8 patients (28.6%) achieved complete dryness. Twenty patients (69%), benefited from biofeedback (SBTG), while there were 9 patients (31%) in the USBTG group. There was no significant difference between the SBTG and USBTG groups in terms of age, body mass index and sex. The average bladder capacity of the patients increased from 215 mL to 257 mL after biofeedback treatment (p<0.001). The TBV/NBC value before treatment was 0.66, while after treatment it was 0.77 (p<0.001). There was a statistically significant difference between the SBTG and USBTG groups in terms of presence of MsE in mother, and both parents (p=0.001, p=0.016, respectively). Conclusion: Biofeedback therapy is a safe, simple, and minimally invasive treatment modality in children with MsE resistant to desmopressin treatment. This treatment, which was found to increase total bladder capacity, may be recommended for children with MsE when conventional desmopressin treatment fails.
