RESUMO

The aim of this study is to investigate whether serum vitamin D level predicts the risk of Peyronie's disease. Calcium and inflammatory cytokines play an important role during fibrocalcification of the plaques in Peyronie's Disease. TGF-ß1 is one of the most fibrogenic cytokines. Increasing serum vitamin D levels is considered that induce expression of TGF-ß1. Serum vitamin D levels and TGF-ß1 are related with calcifications of some soft tissues in previous studies. One hundred and three Peyronie patients and 162 healthy volunteers were included in the study. In both groups, demographic data, medical history, physical examination and erectile capacity were recorded. Serum 25-hydroxyvitamin D, total cholesterol, low-density lipoprotein, high-density lipoprotein, triglyceride and testosterone levels were measured. The mean level of serum 25 (OH) D was significantly higher in men with Peyronie's disease compared with the controls (32.6 ± 7.9 ng/ml vs. 18.5 ± 6.6 ng/ml respectively. p < 0.001). There is a relationship between Peyronie's disease and high serum vitamin D levels. Also, increased low-density lipoprotein and total cholesterol levels, diabetes mellitus, and cardiovascular diseases were associated with Peyronie's disease.

RESUMO

PURPOSE: Peyronie disease (PD) occurs as a result of recurrent microvascular injuries or trauma of the tunica albuginea, although its precise etiology is unknown. Mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT), which are parameters indicative of platelet activity, are considered to be functional markers of platelets involved in the pathophysiology of related inflammatory and vascular diseases. In this study, we aimed to examine the relationship between PD and platelet indices. MATERIALS AND METHODS: We evaluated participants who presented to the andrology department of our institution between December 2015 and May 2018. Ninety-two men with PD and 80 healthy volunteers were included in this study. Participants who had received medical treatment affecting platelets or had any hematologic or systemic diseases were excluded from the study. RESULTS: The mean age of men with PD was 53.8±10.2 years, and the mean age of the control group was 52.2±8.0 years (p=0.465). There were no significant differences in the mean IIEF-5 scores, platelet count, MPV, PDW, or PCT between the patients with and without PD (p<0.05). CONCLUSIONS: No correlations were found between PD and platelet indices. Large-scale prospective cross-sectional studies are needed to elucidate the etiopathogenesis of PD.

RESUMO

The purpose of the study was to investigate variables that may predict ureteral stone impaction and create a new model to predict more accurately stone impaction based on preoperative NCCT findings. Data of 238 patients who underwent URS were analyzed. Stone size, stone location, Hounsfield unit (HU) value of the stone, ureteral wall thickness (UWT) and grade of hydronephrosis were recorded. HU values of the ureter which are measured proximal and distal to the stone were recorded. Subsequently, we determined the factors that could predict the stone impaction in univariate and multivariate logistic regression analysis. After the AUC analysis for these factors, we created a new model to predict more accurately stone impaction. The formula was named Impacted Stone Formula (ISF). Stone impaction verified endoscopically. Predictors of impacted stones were evaluated using univariate and multivariate logistic regression analyses. Diagnostic value for the prediction of stone impaction was analyzed with receiver operating characteristic (ROC) incline. Overall, there were 196 patients included in the study. Multivariate regression analysis revealed that the HU below/above ratio, UWT, and grade of hydronephrosis were the crucial predictors of stone impaction (OR 20.53, p < 0.001; OR 10.55, p < 0.001; OR 5.95, p = 0.004, respectively). The ROC analysis revealed a cutoff value of 15.15 (AUC 0.958, p < 0.001, sensitivity 91.0%, specificity 97.7%) for the ISF. In conclusion, ISF is the most precise preoperative predictor of impacted stones in patients with ureteral stones. ISF could be used by the urologists before treatment to help preoperative planning and perioperative clinical course.

RESUMO

OBJECTIVES: We researched to detect the optimal method for evaluating stone volume, by comparing the ellipsoid formula and 3D reconstructed volume to gold standard of water displacement volume using 3D printed models. METHODS: We retrospectively analyzed out patient database and evaluated 27 patients who had percutaneous nephrolithotripsy. From the DICOM data of patient's preoperative CT images, stone structures were obtained using an image identification system. All DICOM files were saved in the stereolithography file format and a 3D printed model was created. True stone volume was found by water displacement method using this model and this volume compared with ellipsoid formula and 3D-reconstructed volume. RESULTS: Stone volume on water displacement ranged from 0.38-29.8cm3 with a median of 17.5cm3, stone volume on ellipsoid formula ranged from 0.46-34.7cm3 with a median of 19.6cm3 and stone volume on CT based 3D-reconstructed ranged from 0.48-31.8cm3 with a median of 18.9cm3. There was a significant difference between ellipsoid formula and water displacement ( p <   0.0001 ); however, there was no difference between 3D-reconstructed volume and water displacement ( p = 0.051 ). CONCLUSION: Stone volume calculation using CT based 3D-reconstructed algorithm improves the accuracy of stone volume estimation and this measurement is superior to ellipsoid formula.

RESUMO

INTRODUCTION AND HYPOTHESIS: Overactive bladder (OAB) is a syndrome with symptoms such as urinary frequency, urinary urgency and urge incontinence. The aim of this study is to assess the validity and reliability of the Turkish overactive bladder symptom score (OABSS) and to evaluate the results of mirabegron treatment with OABSS. METHODS: The study was carried out with 117 patients who applied to the urology outpatient clinic between June 2018-January 2019. OABSS Turkish validation was developed from the English version. Demographic data of the patients were recorded. The OABSS, overactive bladder questionnaire (OAB-v8) and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) were filled out by the patients. The patients were asked to fill in these questionnaires after 2 weeks. Patients receiving mirabegon treatment were evaluated with the same questionnaires and bladder diaries after 8 weeks. RESULTS: A total of 117 OAB patients, including 82 OAB-wet and 35-OAB dry, were included in the study. The mean age of the patients was 46.79 ± 14.26 (18-78) years, and the mean duration of OAB complaint was 32.28 ± 32.21 months. The mean score of the OABSS is 9.9 ± 3.14. The results of the reliability assessment showed that the intraclass correlation coefficient of the total OABSS score was 0.71 (weighted coefficients of individual item points, 0.635-0.831), and the Cronbach α was 0.736. In the validity analysis, the OABSS total score was highly correlated with that belonging to other questionnaire forms (OAB-v8, ICIQ-SF and bladder diary). After the treatment with mirabegron, mean OABSS scores of the patients improved significantly from baseline to the 8th week (p < 0.001). CONCLUSION: The Turkish version of the OABSS has been approved as a valid and reliable tool for evaluating OAB. Mirabegron used daily improved the symptoms of OAB in patients.

RESUMO

Abstract Purpose: To investigate the relationship between 25-hydroxyvitamin D (25 (OH) D) levels and acquired premature ejaculation (PE). Materials and Methods: A total of 97 patients with acquired PE and 64 healthy men as a control group selected from volunteers without PE attending our Andrology Outpatient Clinic between November 2016 and April 2017 were included the study. All patients were considered to have acquired PE if they fulfilled the criteria of the second Ad Hoc International Society for Sexual Medicine Committee. Premature ejaculation diagnostic tool questionnaires were used to assessment of PE and all participants were instructed to record intravaginal ejaculatory latency time. Vitamin D levels were evaluated in all participants using high performance liquid chromatography method included in the study. Results: Compared to men without PE, the patients with acquired PE had significantly lower 25 (OH) D levels (12.0 ± 4.5 ng/mL vs. 18.2 ± 7.4 ng/mL, p < 0.001). In the logistic regression analysis, 25 (OH) D was found to be an independent risk factor for acquired PE, with estimated odds ratios (95% CI) of 0.639 (0.460-0.887, p = 0.007) and the area under curve of the ROC curve of 25 (OH) D diagnosing acquired PE was 0.770 (95% CI: 0.695 to 0.844, p < 0.001). The best cut-off value was 16 ng/mL with a sensitivity of 60.9%, specificity of 83.5%, PPV of 70.9%, and NPV of 76.4% to indicate acquired PE. Conclusions: This study demonstrates that lower vitamin D levels are associated with the acquired PE. The result of our study showed that the role of serum vitamin D levels should be investigate in the etiology of acquired PE. Perhaps supplementation of vitamin D in men with acquired PE will ameliorate the sexual health of these patients.

RESUMO

OBJECTIVE: To compare the efficacy of statins and ɑ blockers drug therapies for benign prostatic hyperplasia (BPH) in patients with metabolic syndrome (MetS). MATERIALS AND METHOD: A total of three hundred patients were randomly distributed into three groups of one hundred patients each. Group 1 received only ɑ-adrenoceptor antagonist (ɑ-blocker, AB) (Tamsulosin), group 2 received only statin (atorvastatin), and group 3 received AB plus statin (Tamsulosin + Atorvastatin). The efficacy measurement was assessed by analyzing the changes from baseline in the total International Prostate Symptom Score (IPSS), disease-specific QoL question score and maximum urinary flow rate at the end of 6 months in each group and between the three groups. RESULTS: Pre-treatment and post-treatment value of triglycerides (TG), high-density lipoprotein (HDL), and prostate volüme (PV) were not significantly different in AB group, while TG and PV were significantly lower in patients taking statin and combined therapy. The significant decrease was demonstrated in maximum urinary flow rate (Qmax) in three groups. However, the most significant decrease was observed in the combination therapy group. IPSS, postvoid residual urine volüme (PVR), and Quality of Life score (QoL) significantly changed in three groups. CONCLUSION: We recommend of the use of statins in those men with BPH accompanied by MetS in which AB is ineffective alone.

RESUMO

PURPOSE: The aim of the study was to determine the effect of anticholinergics used for overactive bladder treatment on the sexual function of women. METHODS: Between January 2016 and August 2018, over 18 years old, 216 sexual active women with OAB and 165 healthy women as control group were prospectively enrolled in the study. Five different anticholinergics were used for the treatment. Female Sexual Function Index (FSFI), eight-item overactive bladder awareness tool (OAB-V8), and Beck Depression Inventory form were completed before and after 3 months. Baseline and post-treatment scores were compared with a control group of age-matched healthy women. RESULTS: Patients with OAB reported at baseline significantly worse sexual function in all FSFI domains compared to healthy control group (21.47 ± 3.22 vs. 26.79 ± 5.56, p < 0.01). Three months after treatment, over 85% of participants reported clinically relevant improvements in sexual function, with statistically significant changes in mean FSFI scores. CONCLUSIONS: Treatment of OAB with anticholinergics can improve sexual function of sexual active women with OAB. Patients may be informed about this potential benefit of anticholinergic treatment, to improve their sexual function.

RESUMO

Background: To investigate the effect of asymptomatic inflammatory prostatitis on clinical outcomes of patients undergoing trans urethral resection of prostate due to benign prostatic hyperplasia. Materials and methods: A total of 514 patients were enrolled in the study. Clinical parameters and pathological results were compared before and one year after surgery. Results: Of the patients 310 were diagnosed with purely benign prostatic hyperplasia and the others were diagnosed with both prostatic inflamation (cathegory IV) and benign prostatic hyperplasia. No statistical significance was observed between two groups among the parameters including age, prostate volume and post voiding residue (P > 0.05). Patients with prostate inflammation presented higher preoperative International Prostate Symptom Score and lower Qmax values when compared to those without inflammation before trans urethral resection of prostate. Conclusion: Asymptomatic prostate inflammation can lead to worsen lower urinary tract symptoms and urinary flow rate in patients with benign prostatic hyperplasia. Furthermore, the improvement of the complaints after surgery was worse in patients with asymptomatic prostate inflammation. Further well designed prospective-randomised studies are needed to support our findings.

RESUMO

OBJECTIVE: Visceral adiposity index (VAI) is a novel indicator for the assessment of visceral obesity. In this study, we aimed to evaluate the relationship between VAI and premature ejaculation (PE). MATERIALS AND METHOD: A total of 300 men were included in the study. Hundred and fifty men with PE and 150 men without PE (control). All men were evaluated for PE by premature ejaculation diagnostic tool (PEDT). VAI levels were calculated using body mass index (BMI), high density lipoprotein and triglyceride (TG) levels. RESULTS: Mean age of the study groups was 34.3 ± 5.2 (30-60) years and the mean age of the controls were 35.9 ± 5.3 (30-60) years. The men with PE had lower BMI, TG levels, waist circumference (WC) and higher high-density lipoprotein-cholesterol (HDL-C) levels. Mean VAI level was 4.13 ± 0.7 in study group and 5.72 ± 1.6 in control group, respectively. VAI levels were statistically higher in men without PE (p < .001). DISCUSSION: Our cross-sectional study demonstrated a negative correlation between VAI and PE. VAI is superior index for the evaluation and calculation the relationship between obesity and PE.

RESUMO

OBJECTIVE: Visceral adipose index (VAI) is a novel parameter for the evaluation of visceral obesity. As we know that obesity is a risk factor for erectile dysfunction (ED). So, in this study, we compared the VAI levels between the men with ED and without ED. MATERIALS AND METHOD: A total of 177 men were included in the study. Ninety-five men with ED and 82 men without ED (control). All men were evaluated for ED by Index of Erectile Function-5 items (IIEF-5). VAI levels were calculated using body mass index, high density lipoprotein and tryglyceride levels. RESULTS: Mean age was 53.5 (38-69) in men who have ED and 53.1 (34-69) in control. The men with ED had higher body mass index (BMI), triglyceride (TG) levels, higher waist circumference (WC) and lower high-density lipoprotein-cholesterol (HDL-C) levels. Mean VAI level was 5.18 ± 2.50 in study group and 3.47 ± 1.76 in control goup, respectively. VAI levels were statistically higher in men with ED (p < .001). DISCUSSION: The simplicity of WC and BMI measurement and TG and HDL assessment, make VAI an easily applicable index for the evaluation of visceral fat dysfunction. VAI can be useful index for the evaluation and calculation of erectile dysfunction risk.

RESUMO

BACKGROUND: To evaluate men, with lower urinary tract symptoms and newly elevated serum prostate specific antigen (PSA) to determine whether a three-week course of ciprofloxacin antibiotics lowers serum PSA levels and affects recommendations for prostate biopsy. METHODS: A prospective, controlled, single-center prospective trial of 177 men with a newly elevated PSA and lower urinary tract symptoms was conducted. Patients were randomized to three weeks of ciprofloxacin or observation. After three weeks, patients PSA levels and derivatives were repeated. At the end of 3 weeks, all patients underwent TRUS guided systematic 12-core prostate biopsies regardless of the final PSA value. RESULTS: Of 177 men who completed the study, 88 were in the treatment and 89 in the observation group. 46.5% of treatment and %18 of control groups patients PSA levels had decreased after 3 weeks and a significant PSA reduction was observed in the treatment group compare to control group (p: 0.035) but no significant prostate cancer detection rates were observed between the groups (p: 0.418). Also, in the treatment group prostate cancer detection rate was significantly higher in patients whom PSA levels were decreased (p: 0.011). CONCLUSION: This study has shown that, use empirical antibiotic treatment decreased the PSA levels but did not have any effect on prostate cancer detection. In addition, prostate cancer detection rates were found to be higher in patients with reduced PSA levels after treatment. Therefore, it may not be safe to rule out biopsies in patients who achieve a satisfactory PSA response to antibiotics.

RESUMO

PURPOSE: We aimed to investigate relationship between metabolic syndrome and calcium-oxalate stone formation. MATERIALS AND METHODS: Between January 2008 and February 2015 we retrospectively investigated biochemical parameters and anthropometric characteristics (height, weight, and waist circumference) of 198 patients who had calcium-oxalate stones and we also randomly selected 200 participants who had no history of urolithiasis as the controls. RESULTS: The presence of obesity increased the risk of calcium stones in both men (P = .003, OR = 2.92) and women (P = .03, OR = 2.18). Diabetes was significantly correlated to the risk of calcium stones (P = .04, OR = 1.94). However, when calculated separately for men and women, diabetic men had a higher risk of calcium-oxalate stone disease (P = .04, OR = 2.59), but diabetic women did not (P > .05). Hypertension also significantly increased the risk of calcium stones when compared with normotensive individuals (P = .0001, OR = 3.03). CONCLUSION: The risk for the development of calcium-oxalate stone disease is most significantly associated with the patient's body mass index and the presence of hypertension.

RESUMO

INTRODUCTION: Ureteral obstruction is a common pathology and caused kidney fibrosis and dysfunction at late period. In this present, we investigated the antifibrotic and antiinflammatory effects of montelukast which is cysteinyl leukotriene receptor antagonist, on kidney damage after unilateral ureteral obstruction(UUO) in rats. MATERIALS AND METHODS: 32 rats divided four groups. Group 1 was control, group 2 was sham, group 3 was rats with UUO and group 4 was rats with UUO which were given montelukast sodium (oral 10 mg/kg/day). After 14 days, rats were killed and their kidneys were taken and blood analysis was performed. Tubular necrosis, mononuclear cell infiltration and interstitial fibrosis scoring were determined histopathologically in a part of kidneys; nitric oxide(NO), malondialdehyde(MDA) and reduced glutathione(GSH) levels were determined in the other part of kidneys. Urea-creatinine levels were investigated at blood analysis. Statistical analyses were made by the Chi-square test and one-way analysis of variance (ANOVA). RESULTS: There was no difference significantly for urea-creatinine levels between groups. Pathologically, there was serious tubular necrosis and fibrosis in group 3 and there was significantly decreasing for tubular necrosis and fibrosis in group 4(p<0.005). Also, there was significantly increasing for NO and MDA levels; decreasing for GSH levels in group 3 compared the other groups(p<0.005). CONCLUSION: We can say that montelukast prevent kidney damage with antioxidant effect, independently of NO.

RESUMO

OBJECTIVE: To evaluate the relationship among urolithiasis, metabolic syndrome (MetS) and serum testosterone (T) level in men. MATERIAL AND METHODS: 513 men older than 18 years were enrolled in this study: 313 of the subjects had a history of stones (group 1) and 200 had no history of stones (controls, group 2). Early morning T levels were recorded and anthropometric measurements were investigated to evaluate MetS. Analyses were completed using chi-square tests. RESULT: Serum T level was lower in stone forming patients than control subjects and 161 (%51.4) men in group 1 and 92 (%46) men in group 2 were diagnosed with metabolic syndrome. T level was found lower limit (< 285 ng/dl) in the MetS and urolithiasis group (p 0.002, OR 2.71). CONCLUSIONS: We found low testosterone levels in the patients with stone disease and prevalence of the MetS in men with urolithiasis was higher than in men without stone disease. Our findings show that levels of testosterone had no effect on stone formation, but the factors that cause stone formation can have an effect on the level of testosterone.

RESUMO

Sexual dysfunction in general and erectile dysfunction (ED) in particular significantly affect men's quality of life. Some patients who have ED, also develop osteoporosis. So, in this study we investigated the relationship between erectile dysfunction and osteoporosis in men. 95 men with erectile dysfunction and 82 men with normal sexual function were included in the study. The men's sexual functions were evaluated by International Index of Erectile Function-5 items (IIEF-5). All men received a Dual Energy X-ray Absorptiometry (DEXA; Hologic) scan to measure bone mineral density (BMD) for osteoporosis. Chi-square test was used for statistical analysis. Mean age was 53.5 (38-69) in ED group and 50.1 (31-69) in control group. In ED group the men have lower T score levels than those of the control group. In conclusion, the men who have erectile dysfunction were at more risk for osteoporosis. The results of the present study demonstrate that the men with erectile dysfunction have low bone mineral density and they are at higher risk for osteoporosis. Because of easy and noninvasive evaluation of osteoporosis, patients with ED should be checked for bone mineral density and osteoporotic male subjects should be evaluated for ED.

RESUMO

AIMS: Ureteral obstruction may cause permanent kidney damage at late period. We know that the pomegranate extract (PE) play a strong role on removal of free oxygen radicals and prevention of oxidative stress. In the current study study, we evaluated the effect of PE on kidney damage after unilateral ureteral obstruction (UUO). SETTINGS AND DESIGN: A total of 32 rats were divided into four groups. Group 1 was a control, Group 2 was a sham, Group 3 was rats with UUO and Group 4 was rats with UUO that were given PE (oral 100 µL/day). After 14 days, rats were killed and their kidneys were taken and blood analysis was performed. SUBJECTS AND METHODS: Tubular necrosis, mononuclear cell infiltration, and interstitial fibrosis scoring were determined histopathologically in a part of kidneys; nitric oxide (NO), malondialdehyde (MDA), and reduced glutathione (GSH) levels were determined in the other part of kidneys. STATISTICAL ANALYSIS USED: Statistical analyses were performed by the Chi-square test and one-way analysis of variance. RESULTS: There was no difference significantly for urea-creatinine levels between groups. Pathologically, there was serious tubular necrosis, mononuclear cell infiltration and fibrosis in Group 3, and there was significantly decreasing for tubular necrosis, mononuclear cell infiltration and fibrosis in Group 4 (P < 0.005). Furthermore, there was significantly increasing for NO and MDA levels; decreasing for GSH levels in Group 3 compared the other groups (P < 0.005). CONCLUSIONS: We think that the PE prevents kidney damage by decreasing oxidative stress in kidney.

RESUMO

Introductıon Ureteral obstruction is a common pathology and caused kidney fibrosis and dysfunction at late period. In this present, we investigated the antifibrotic and antiinflammatory effects of montelukast which is cysteinyl leukotriene receptor antagonist, on kidney damage after unilateral ureteral obstruction(UUO) in rats. Mateirıals and Methods 32 rats divided four groups. Group 1 was control, group 2 was sham, group 3 was rats with UUO and group 4 was rats with UUO which were given montelukast sodium (oral 10 mg/kg/day). After 14 days, rats were killed and their kidneys were taken and blood analysis was performed. Tubular necrosis, mononuclear cell infiltration and interstitial fibrosis scoring were determined histopathologically in a part of kidneys; nitric oxide(NO), malondialdehyde(MDA) and reduced glutathione(GSH) levels were determined in the other part of kidneys. Urea-creatinine levels were investigated at blood analysis. Statistical analyses were made by the Chi-square test and one-way analysis of variance (ANOVA). Results There was no difference significantly for urea-creatinine levels between groups. Pathologically, there was serious tubular necrosis and fibrosis in group 3 and there was significantly decreasing for tubular necrosis and fibrosis in group 4(p<0.005). Also, there was significantly increasing for NO and MDA levels; decreasing for GSH levels in group 3 compared the other groups(p<0.005). Conclusıon We can say that montelukast prevent kidney damage with antioxidant effect, independently of NO. .

RESUMO

OBJECTIVES: In recent years, it has been shown that there is association between metabolic syndrome and urinary stone disease. Stone disease and erectile dysfunction (ED) are considered as systemic diseases which are associated with hormonal and metabolic disorders. Therefore we investigated the relationship between ED and urinary tract calculi. MATERIAL AND METHODS: 98 male patients with urolithiasis and 59 randomly selected male patients without stone disease were included in the study. Serum testosterone (T) levels were measured and International Index of Erectile Function (IIEF)-15 questionnaire forms were used to assess ED. RESULTS: The prevalence of ED was found 29% (29 patients) in the urolithiasis group. Sixty-nine patients (71%) had no ED; 16 (16.3%) had mild, 5 (5.1%) had moderate and 8 (8.2%) had severe ED. None of the patients in the control group had severe or modarete ED, six patients (10.2%) had mild ED. Serum T levels were detected at the level of biochemical hypogonadism on 13 patients with stones (13.3%) and T levels were detected at the lower limit in 18 (18.3%) patients. CONCLUSION: In our study we have shown that ED and low T levels are significantly associated with urolithiasis. We propose that the patients with urolitiasis should be evaluated for ED and hypogonadism.
