ABSTRACT
Hematuria is the most common symptom of bladder cancer (BCa). It is well-known that the frequency of hematuria increases with the use of antithrombotic drugs (ATDs). We designed our study with the hypothesis that patients using antithrombotic drugs who present with the complaint of hematuria and are subsequently diagnosed with BCa may receive an earlier diagnosis, leading to lower tumor grades and stages. Data of 441 consecutive patients who presented to our urology outpatient clinic with macroscopic hematuria between 2020 and 2023 were retrospectively evaluated. A total of 88 patients (21.4%) with a primary diagnosis of BCa were included in our study. Patients were divided into 2 groups: those using ATDs during the episode of macroscopic hematuria (group 1) and those not using ATDs (group 2). Univariate and multivariate binary logistic regression analysis was performed to identify risk factors that could predict tumor grade. The incidence of multiple tumors (>1) was significantly lower in patients using ATDs (Pâ =â .033). The number of patients with tumor size larger than 3 cm was significantly higher in the group not using ATDs (Pâ =â .005). The rates of pathological T1 stage in the group using ATDs were significantly lower than those in the nonuser group (Pâ =â .038). According to the results of the multivariate model, the effect of pathology stage and ATD use on predicting tumor grade was significant (Pâ =â .002 and Pâ <â .001, respectively). The probability of having a high-grade tumor in patients with pathology stage T1 was 5.32 times higher than in patients with pathology stage TA. The probability of having a high-grade tumor in patients not using ATDs was 7.73 times higher than in those using ATDs. The effect of pathology stage and ATD use on predicting tumor grade was found to be significant. The probability of having a high-grade tumor was higher in patients not using ATDs compared to those using ATDs. In light of these results, we can state that the use of ATDs is a positive predictive factor in the early diagnosis of BCa, bringing along the chance of early diagnosis and treatment.

Background: The impact of the coronavirus disease 2019 (COVID-19) pandemic on patient decision making remains uncertain. This study aimed to investigate the effect of the pandemic on treatment preferences of patients with proximal ureteral stones. Materials and methods: Retrospective data regarding treatment preferences of patients diagnosed with symptomatic proximal ureteral stones between July 2018 and November 2021 at a single center were analyzed. Data from 493 patients were analyzed according to 2 groups, including patients diagnosed during the COVID-19 pandemic and those diagnosed during an equivalent period of time before the pandemic. Results: Preference for conservative treatment increased during the COVID-19 pandemic (p = 0.009). In patients who had previously undergone shock wave lithotripsy (SWL), the preference for SWL decreased and the preference for conservative treatment increased during the COVID-19 pandemic (p = 0.042). Multiple logistic regression analysis revealed a significant correlation between a preference for conservative treatment during the pandemic and no prior spontaneous stone passage (p = 0.003; odds ratio [OR], 2.48; 95% confidence interval [CI], 1.45-4.23), no hydronephrosis (p = 0.035; OR, 3.57; 95% CI, 1.34-9.49), and a visual analog scale score of 4 or less (p = 0.018; OR, 1.97; 95% CI, 1.15-3.38). Conclusions: A significant increase in the preference for conservative treatment was observed among patients diagnosed during the pandemic, and patients with a history of SWL demonstrated a preference shift from SWL to conservative treatment.
ABSTRACT
OBJECTIVE: The aim of this study was to explore the criteria that can predict bladder cancer among the lesions that could not be differentiated from intravesical prostate protrusion (IPP) and to create a scoring system using these criteria. METHODS: A retrospective analysis was made of patients with an ultrasound report indicating lesions in the bladder neck, for which differentiation between bladder cancer and IPP could not be determined. A total of 174 patients diagnosed with bladder cancer (n=102) or benign prostate lesion (n=72) according to the biopsy results were enrolled in the study. Hemoglobin, prostate-specific antigen (PSA), prostate volume (PV), bladder wall thickness (BWT), lesion height (LH), and the ratio of lesion width to base (LW/B) were compared between the two groups. RESULTS: ROC analysis revealed an AUC value >0.7 for all factors, and the best cut-off value was identified for each factor. In the multivariate analysis, by determining a score for each factor according to the ORs, the BCa-IPP scoring system was developed to provide a total score in the range of minimum 0 and maximum 15. In the ROC analysis, the AUC value was 0.954 (95% CI: 0.923-0.986) for the BCa-IPP score. The best cut-off value was found to be 10, with sensitivity of 0.93 and specificity of 0.85. CONCLUSION: Using simple laboratory and ultrasound findings, the BCa-IPP scoring system was created, which was seen to have high predictive value and can be easily applied in the clinic. The BCa-IPP scoring system is a non-invasive test that can be successfully applied for the differentiation of bladder cancer from benign lesions.
ABSTRACT
PURPOSE: To evaluate the effect of the reverse Trendelenburg position in patients undergoing ureteroscopic lithotripsy for proximal ureteral stones. METHODS: The study included 167 patients who underwent ureteroscopic lithotripsy for proximal ureter stones between December 2020 and September 2022. The patients were randomly assigned to one of three groups: standard lithotomy (n:55), 10° reverse Trendelenburg (n:55), and 20° reverse Trendelenburg (n:57). Preoperative information, including age, sex, body mass index (BMI), previous shock wave lithotripsy (SWL), stone side, volume, and density, distance to the ureteropelvic junction (UPJ) of the stone, and hydronephrosis degree. Stone-free status was evaluated with computed tomography (CT) at 4 weeks postoperatively. The groups were compared in respect of stone migration, stone-free rate, use of flexible ureterorenoscope, operating time, postoperative length of stay in the hospital, and complications. RESULTS: No statistically significant difference was determined between the groups with respect to age, sex, BMI, previous SWL, stone side, volume and density, distance to the UPJ of the stone, and hydronephrosis degree (p > 0.05 for all). Statistically significant differences were determined between the groups with respect to stone migration (p = 0.001), stone-free rate (p < 0.001), use of flexible ureterorenoscope (p = 0.01), operating time (p < 0.001), hospital length of stay (p < 0.001), postoperative fever (p = 0.002), and total complications (p = 0.01). CONCLUSION: A new patient position is presented in this study, which can be used in ureteroscopic lithotripsy performed for proximal ureteral stones. The reverse Trendelenburg position constitutes a surgical method that can be used safely and successfully in the treatment of proximal ureteral stones. TRIAL REGISTRATION NUMBER: NCT04894058, 05/21/2021, Prospectively registered.

The prevalence of penile calcification in the population remains uncertain. This retrospective multicenter study aimed to determine the prevalence and characteristics of penile calcification in a large cohort of male patients undergoing non-contrast pelvic tomography. A total of 14 545 scans obtained from 19 participating centers between 2016 and 2022 were retrospectively analyzed within a 3-months period. Eligible scans (n = 12 709) were included in the analysis. Patient age, penile imaging status, presence of calcified plaque, and plaque measurements were recorded. Statistical analysis was performed to assess the relationships between calcified plaque, patient age, plaque characteristics, and plaque location. Among the analyzed scans, 767 (6.04%) patients were found to have at least one calcified plaque. Patients with calcified plaque had a significantly higher median age (64 years (IQR 56-72)) compared to those with normal penile evaluation (49 years (IQR 36-60) (p < 0.001). Of the patients with calcified plaque, 46.4% had only one plaque, while 53.6% had multiple plaques. There was a positive correlation between age and the number of plaques (r = 0.31, p < 0.001). The average dimensions of the calcified plaques were as follows: width: 3.9 ± 5 mm, length: 5.3 ± 5.2 mm, height: 3.5 ± 3.2 mm, with an average plaque area of 29 ± 165 mm² and mean plaque volume of 269 ± 3187 mm³. Plaques were predominantly located in the proximal and mid-penile regions (44.1% and 40.5%, respectively), with 77.7% located on the dorsal side of the penis. The hardness level of plaques, assessed by Hounsfield units, median of 362 (IQR 250-487) (range: 100-1400). Patients with multiple plaques had significantly higher Hounsfield unit values compared to those with a single plaque (p = 0.003). Our study revealed that patients with calcified plaques are older and have multiple plaques predominantly located on the dorsal and proximal side of the penis.
ABSTRACT
INTRODUCTION: The aim of the study was to determine the correlation between the dwelling time for a ureteral stent placed for passive dilation after impassable ureteroscopy and success and complications. METHODS: A retrospective evaluation was made of patients who underwent stent placement after impassable ureteroscopy and a repeat ureteroscopy due to kidney stones. A total of 161 patients were included in the study between 2015 and 2022. Demographic, clinical, preoperative, and perioperative data were collected. Logistic regression analyses were performed on the data showing a significant difference in the univariate analyses performed to determine the predictive factors of ureteroscopy after the stent dwelling period in terms of stone-free status and perioperative complications. RESULTS: Stone-free status was achieved in 110 (68.3%) of 161 patients, and perioperative complications were observed in 41 (25.4%). Factors that affected the stone-free status were determined as the dwelling time and the S-ReSC score, while factors affecting perioperative complications were the stent dwelling time and the operation time. The stone-free rates were observed to increase from 46.4% in the first 2 weeks to 72.9% after the 2nd week, an increase of 1.5-fold. Perioperative complications were determined at the rate of 17.5% during the first 5 weeks and increased 2.1-fold to 37.5% after the 5th week. CONCLUSION: It can be recommended that great care is taken during the stent dwelling period and ureteroscopy should be performed within 5 weeks (14-35 days) but no earlier than 2 weeks, so as not to affect the success of the procedure.

INTRODUCTION AND OBJECTIVES: Although erectile dysfunction is frequently seen in hemodialysis patients, little information is documented about the efficacy of phosphodiesterase type 5 (PDE5) inhibitors and almost all the articles evaluate sildenafil. We aimed to evaluate the efficacy of chronic low dose tadalafil in this group of patients. MATERIALS AND METHODS: The International Index of Erectile Function (IIEF) questionairre was administered to patients under hemodialysis program. A total of 58 patients with ED (International Index of Erectile Function (IIEF) score < 26), each having a stable partner, between 18-60 years, receiving routine outpatient HD matched the inclusion criteria and divided into two equal groups; placebo and tadalafil 5 mg/3 days. Changes of the IIEF score was recorded after one month of treatment. RESULTS: The mean age of the patients was 50.0±9.93 years. Duration of dialysis was 57.5(12-108) months. Hemoglobin (g/dl) and creatinin clearence (ml/Min) values of placebo and tadalafil groups were not significantly different; 10.9(8.8-14) vs 10.7(8.9-13) and 5.7±1.3 vs 6.0±1.4 respectively. There was a statistically significant increase for all subgroups related erectile dysfunction 9.28±4.17 vs 21.07±5.99 (p=0.037), intercourse satisfaction 8(3-9) vs 10(5-15) (p<0.001), orgasmic function 4(1-10) vs 8(4-10) (p<0.001), sexual desire 4(2-10) vs 7(3-9) (p<0.001) and general satisfaction 5(2-9) vs 6(2-9) (p<0.001) with low dose of tadalafil at the end of four weeks without any major side effects. There was only a significant increase in sexual desire 4(3-9) vs 6(4-10) (p<0.001),in placebo group with an insignificant change in all other IIEF domains. Total IIEF score of the placebo group was insignificantly increased from 21.13±7.73 to 21.99±7.04 (p=0.771) while there was a statistically significant increase in tadalafil group; from 20.87±8.84 to 30.75±7.04 (p<0.001). CONCLUSIONS: Tadalafil 5 mg once in three days is appear to be efficacious and well tolerated for the treatment of ED in hemodialysis patients.

BACKGROUND: The aim of the present study is to investigate the efficiency of roflumilast and ibuprofen in an experimental rat testicular ischemia reperfusion injury model in the light of histological and biochemical data. METHODS: A total of 32 prepubertal male rats were randomly divided into four groups as G1: Control Group (testicular torsion/detorsion + saline (0.9% of 2 ml) was applied). G2: Sham Group only right scrotal incision was performed; G3: Ibuprofen Group (tes-ticular torsion/detorsion + ibuprofen administration); and G4 Roflumilast Group (testicular torsion/detorsion + roflumilast adminis-tration). Oxidative markers such as malondialdehyde (MDA), myeloperoxidase (MPO), total sulfhydryl (TSH), and nitrite (NO) levels as well as histopathological changes were analyzed. RESULTS: Tissue MPO, MDA, and NO levels were significantly higher and TSH levels significantly lower in control group compared to sham group (p<0.001). The histopathologic scores of drug groups (Groups 3 and 4) were significantly lower than group 1 (p<0.001). In comparison of Group 3 and Group 4 with each other, the mean values of MPO and MDA were statistically significantly lower in Group 4 (p<0.001). A higher mean value of TSH was found in Group 3 without statistically significance (p=0.32). There was also an insignificant decrease in mean NO values of Group 3 compared to Group 4 (p=0.44). In comparison of drug groups, Group 4 had statistically insignificant better scores. CONCLUSION: Our results indicate that administrating ibuprofen and roflumilast reduced testicular ischemia reperfusion injury in rat testis torsion model. In comparison, roflumilast is found to be more beneficial.

OBJECTIVES: To evaluate the impact of the presence and severity of urinary incontinence (UI) on pregnancy-related anxiety. STUDY DESIGN: This prospective case-control study included 160 pregnant women. Pregnant women with UI (n = 80) were compared with continent pregnant women (n = 80; control group) in terms of scores on the Incontinence Consultation Questionnaire-Short Form (ICIQ-SF) and the Pregnancy-related Anxiety Questionnaire-Revised 2 (PRAQ-R2) scale. Gynaecological examination was performed, and pelvic organ prolapse was diagnosed using the Pelvic Organ Prolapse Quantification system. UI was classified as stress UI (SUI), urge UI (UUI) or mixed UI (MUI). RESULTS: The total PRAQ-R2 score was significantly higher in all pregnant women with UI, as well as the UI subgroups, compared with the control group [mean ± standard deviation; 21.77 ± 8.1 (UI), 19.39 ± 6 (SUI), 20.13 ± 7.2 (UUI) and 28.1 ± 9.5 (MUI) vs 15.76 ± 5.9 (control group); p < 0.0001, p = 0.002, p = 0.012 and p < 0.0001, respectively). Significant positive correlation was found between the total ICIQ-SF and total PRAQ-R2 scores (r = 0.533; p < 0.0001). The score for the fear of giving birth domain in PRAQ-R2 was higher in women with SUI and MUI compared with the control group (9.5 ± 4 and 11.1 ± 2.6 vs 5.43 ± 2.4; p < 0.0001). Concern about own appearance was greater in the UUI and MUI groups compared with the control group (9.68 ± 4.5 and 7.8 ± 3.1 vs 4.85 ± 2.3; p < 0.0001). CONCLUSION: To the authors' knowledge, this is the first study to report the impact of the presence and severity of UI on pregnancy-related anxiety. The current findings show that anxiety may be an important psychosocial consequence of UI in pregnancy. This may lead to a clinical approach focusing on both the physical and psychological well-being of pregnant women with UI.

PURPOSE: We aimed to investigate the effects of obturator nerve block (ONB) on obturator reflex, incomplete resection, perforation, progression and recurrence of tumor, presence of muscle tissue in the specimen, need for a second transurethral resection (TURBT) of bladder tumors, and postoperative complications in patients who underwent TURBT for intermediate-high risk lateral wall non-muscle invasive bladder cancers (NMIBC). MATERIAL AND METHODS: Patients were assigned to one of two groups by drawing lots: ONB or none ONB. Early and late recurrence, tumor progression, obturator reflex beat, incomplete resection, perforation, presence of muscle layer in pathology, second TURBT application, operation time, postoperative hospital stay, and complications were compared between the two groups. RESULTS: The median follow-up time of the study was32 (23-41) months. Interquartile range (IQR) was 9. Tumor recurrence at the 3rd month cystoscopy controls was observed in 5 (9.8%) patients in the ONB group, while it was observed in 11 (20.8%) patients in the nONB group (p=0.01). Late tumor recurrence was observed in 10 patients (19.6%) in the ONB group, and in 20 patients (37.7%) in the nONB group (p=0.041). The RFS rate at 12th month was 84% in the ONB group, 69% in the nONB group, 79% in the ONB group at 36th month, and 58% in the nONB group at 36 months, the PFS rate was 94% in the ONB group, while it was 85% in the nONB group (p=0.041). CONCLUSION: Our study showed that ONB decrease the early and late recurrence and increase recurrence free survival in patients with intermediate-high risk lateral wall bladder cancer.

BACKGROUND: Hypospadias is a common congenital anomaly which is determined as an abnormal urethral opening on the ventral face of penis. The purpose of this rat model study was to research the effect of topically applied Aloe vera after a tubularized incised plate urethroplasty (TIPU). METHODS: The TIPU model was applied to male Wistar albino rats. A total of 30 rats were randomly grouped into 3 groups of 10. Group I was assigned as the control group, treated with 0.9% saline only twice a day for 15 days. Group II received topical Aloe vera gel once a day and Group III received Aloe vera gel twice a day. Spongiofibrosis was graded as 0: none, 1+:≤10% tissues involved, 2+:10%-49% tissues involved, 3+: ≥ 50% tissues involved. RESULTS: A higher degree of fibrosis and inflammation was determined in the Group I subjects than in Groups II and III. Fibrosis of grade 3+ was observed in 33% of the control group and not in any of the two Aloe groups (p = 0.043). Inflammation of grade 3+ was seen in 66.7% of the control group, in 10% of Group II, and in 33% of Group III (p = 0.02). CONCLUSIONS: The topical application of Aloe vera to a surgically created tubularized incised plate urethroplasty model decreased inflammation and fibrosis that may affect the success rates of this operation.

OBJECTIVE: We aimed to determine the interest and changing trends over time in the diagnosis and treatment of bladder cancer and its awareness campaign by examining the Google Trends application as an indicator of people's interest globally. METHODS: Using the Google Trends application, we determined the yearly and country-based relative search volumes of the term "bladder tumor" and of the methods used in the diagnosis and treatment of bladder cancer in the period from January 2004 to December 2019. We compared the median relative search volumes found in the period 2004-2011 (Period 1) with those found in the period 2012-2019 (Period 2). RESULTS: We found that the median relative search volume for bladder cancer decreased in period 2 and this was parallel to the decrease in the incidence rates in North America and Australia (p<0.001). We found that the bladder cancer awareness month did not cause an increase in the online interest (p>0.05). We found that the median relative search volumes of diagnostic cystoscopy and cytology were higher than those of molecular markers and imaging methods in line with guidelines (p<0.001). Also, TURBT was the most sought-term among treatment methods with increasing popularity in the second period (p<0.001). CONCLUSION: People use the internet intensively to search for information about bladder cancer. We think that several types of web-based applications such as "Google Trends" can help determine the behavioural patterns and tendencies of bladder cancer patients and affect the clinical decision-making processes, as well as readily determining the impact of cancer awareness campaigns to bring about an increased awareness in the society for the recognition of the importance of an early diagnosis.

INTRODUCTION: Erectile dysfunction (ED) is the inability to achieve or maintain erection sufficient for satisfactory sexual performance. Although the definition is well known, there are controversial issues about the effects of hormones and inflammation on ED. OBJECTIVES: We aimed to compare the clinical value of the hormonal and inflammation parameters in sexual dysfunction. MATERIALS AND METHODS: A total of 152 patients diagnosed with erectile dysfunction between September 2018 and March 2019 and 101 healthy males were included in this prospective study as case group and control group, respectively. The 152 patients were divided into three groups based on their total International Index of Erectile Function (IIEF) scores: (I) severe ED, (II) mild-moderate ED and (III) mild ED. All groups were compared in terms of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and total testosterone (TT), estradiol, prolactin, testosterone-to-estradiol ratio and 25 (OH) vitamin D. RESULTS: Patient and control groups differed significantly in term of NLR, PLR, prolactin and vitamin D (p<0.001, p=0.004, p=0.002, p<0.001, p<0.001, respectively). NLR was more significant in determining the severity of ED (p<0.001). It was observed that libido score (the total score of IIEF items #11 and #12) was negatively associated with prolactin and NLR (p<0.001, p=0.023, respectively), was positively associated with vitamin D and TT (p<0.001, p=0.02, respectively), and was lower in severe ED patients. CONCLUSIONS: Although more clinical studies are needed, we think that our findings may be useful on these controversial issues of ED.

OBJECTIVE: To determine the outcomes of retrograde intrarenal surgery (RIRS) and its complications in both young and elderly patients. STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: Departments of Urology, University of Health Sciences, Ankara Research and Training Hospital, Ankara, and Çorum Hitit University, Çorum, Turkey from April 2019 to January 2020. METHODOLOGY: Patients with kidney stones up to 3 cm in maximal diameter on computarised tomography (CT) scan, were divided into two groups according to age (<60 vs. ≥60 years ). RIRS was performed. Demographics, clinical data, and complications were recorded and compared. RESULTS: Mean age of 78 patients was 52.47 ±13.28 years. There were no significant difference in gender, American Society of Anesthesiology (ASA) scores, operation time, number of multiple sessions, success rates of outcome and complication rates between groups. At the end of the first session, stone-free rates were 91.1% vs 87.9% in younger and elderly groups, respectively; while, after the second session, all patients were stone-free in both groups. Fever, hematuria (macroscopic, more than 24 hours), and perirenal hematoma were the observed complications. Postoperative hematocrit levels significantly decreased without any need of transfusion; there were significant differences in the preoperative and postoperative creatinine levels ( p=0.002) in the older group. CONCLUSION: RIRS is a safe and effective method for treating kidney stones up to 3 centimeter diameter in all age groups. Although hemorrhagic events are mostly clinically unremarkable, there is a risk of renal function impairment in older (≥60 years) patients. Preoperative hydration and postoperative close follow-up is important. Key Words: Retrograde intrarenal surgery, Elderly, Effectiveness, Safety.

Ranolazine is a drug used in refractory chronic stable angina. In this study, it was aimed to evaluate the protective effect of ranolazine in a testis torsion model in light of objective biochemical and pathological data. A total of 24 pre-pubertal male Wistar albino rats were separated into three groups of 8 as the sham group, control group and ranolazine group. Testis torsion was applied for 3 hr to all the rats in Group Control and Group Ranolazine. In Group Control, 0.9% NaCl was applied 1 hr after the torsion. In Group Ranolazine, ranolazine 30 mg/kg was dissolved in a 0.9% NaCl solution and was administered intraperitoneally 1 hr after torsion. Histopathological evaluation was made using the Cosentino score. As a result of the objective biochemical and pathological criteria used in this study, this protective effect of ranolazine was observed in testis torsion. The results obtained in this study may suggest that ranolazine is a drug that could be applied after detorsion to patients diagnosed with torsion.

PURPOSE: Renal ischemia-reperfusion injury (RIRI) may occur secondary to several reasons leading to renal failure. Coenzyme-Q10 (CoQ10) is a well-known antioxidant. However, the effects CoQ10 against RIRI have not been evaluated. Our aim was to evaluate protective effects of CoQ10 to renal ischemia-reperfusion by biochemical, immunohistochemical and scintigraphic findings. METHODS: Thirty Wistar-albino rats were randomly separated into groups of 10; Group Sham; Group ischemia-reperfusion (IR) had left renal pedicle clamping; Group CoQ10+IR had IR and CoQ10. Twenty-four hours later after reperfusion, scintigraphy was performed and after that, rats were sacrificed. To demonstrate effects of RIRI, serum urea and creatinine levels and tissue levels oxidative stress markers were evaluated. Both kidneys were subjected to histopathological evaluation and to confirm RIRI-induced immunohistochemical aspects of apoptosis, terminal-deoxynucleotidyl-transferase mediated-deoxyuridine-triphosphate-nick-end-labeling assay and caspase-3 were assessed. RESULTS: Tissue oxidative stress, histopathologic changes, apoptosis scores and quantitative scintigraphic parameters were significantly higher in Group IR compared with Group Sham. Although tissue oxidative stress levels and histopathologic changes were not significant, quantitative scintigraphic parameters of contralateral kidney of Group IR were significantly increased. Compared with Group IR, Group CoQ10+IR presented decreased tissue oxidative stress levels; decreased scores of histopathology and apoptosis; and decreased quantitative scintigraphic parameters with increased split renal function in ischemic kidney. CONCLUSIONS: Our results suggest that other than its antioxidant properties, CoQ10 shows antiperoxidative, antiapoptotic and antiinflammatory potential in protecting renal functioning of ischemic kidney. Furthermore, our results show that renal scintigraphy is a feasible method to detect early changes in renal functioning after RIRI.

To examine the relation between NLR (neutrophil-lymphocyte ratio) and PLR (platelet-lymphocyte ratio) rates and the severity of ED (erectile dysfunction) and the effect of tadalafil 5 mg/day on these, a total of 143 patients were retrospectively evaluated. Sixty-three patients with ED who came for follow-up examinations in the 1st month of the treatment were included as the study group, and 80 men who were not diagnosed with ED were as the control group. The age and Charlson Comorbidity Indexes (CCI) of the study and control groups were compared with the IIEF 5, NLR and PLR values before and after the treatment. The mean age and median CCI were higher in the severe ED group (p < 0.05). The mean NLR and PLR values were lower in the control group (p < 0.001). In the study group, the NLR and PLR values decreased with the increase in the IIEF 5 scores (p < 0.001). The ROC curve was significant for the NLR and PLR scores (AUC = 0.779, [95% CI: 0.698-0.860]; AUC = 0.754, [95% CI: 0.670-0.838] p < 0.001). Although more prospective and randomized studies are needed, the systemic inflammation decreases and the clinical symptoms improve in patients who use tadalafil 5 mg/day.

OBJECTIVE: To evaluate the variables of cystic renal lesions to predict the renal tumors. STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: Urology Department, Ankara Yüksek Ihtisas, Samsun Research and Training Hospitals, Turkey, from January 2013 to June 2017. METHODOLOGY: Records of patients with renal cystic lesions were retrospectively evaluated. Preoperative CT results in terms of diameter number and enhancement; and clinical variables such as gender body mass index [(weight (kg)/ height²(m)] and smoking status were recorded. Student's t-test and ANOVA were used for determing significance, which was set at p<0.05. RESULTS: Due to pathology results, all group I patients were benign, 7.9% (3/38) of group II, 31.8% (7/22) of group II-F, 55.3% (21/38) of group III, 69% (40/58) group IV patients were found to be malignant. For clinical factors, obesity and smoking, while for radiological parameters, about 59.3 +11.7 HU enhancement were found to be predictor significant of malignancy (all p<0.05). No significant difference was observed between cystic lesion diameter number or laterality (right/left) and malignancy. CONCLUSION: Renal cysts have a high malignancy possibility in the patients with history of smoking in the past or actively, high BMI, and preoperative CT with about 59.3 +11.7 HU post-contrast enhancement.

Retrograde intrarenal surgery (RIRS) is an efficient method for kidney stones with low complication rates. Reported here is an unusual complication of this surgery; a retroperitoneal hematoma 8x7.5x5 cm in dimension in a 40-year female, which was completely resolved by conservative treatment. This is the first reported case of retroperitoneal hematoma following RIRS in the literature. Although this technique is safe, feasible and minimally invasive for kidney stones, urologists should be vigilant for such a complication.

OBJECTIVE: To evaluate the safety and effectiveness of fluoroscopy-free RIRS (Retrograde intrarenal surgery) method in urolithiasis. STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: Department of Urology, Hitit University Corum Training and Research Hospital, Corum, Turkey, from October 2014 and October 2017. METHODOLOGY: Preoperative and postoperative data of 62 cases of renal calculi that underwent fluoroscopy-free RIRS procedure by a single surgeon were prospectively evaluated. All manipulations were performed with a novel technique; under direct vision during the operation. Fluoroscopy device was kept at hand in the operating room, but was not used. RESULTS: The mean age was found as 51.73 ±12.63 (22-82) years. Fortyone patients (66.1%) were males and 21 (33.9%) were females. The mean size of stones were 19.29 ±7.64 (10-40) mm. The stone-free rate was calculated as 42 (67.7%) cases in a single session one month after the surgery, and 15 (24.2%) cases after the second session at the postoperative first month. A total of 57/61 (91.9%) patients were stone-free after the second procedure. No major intraoperative and postoperative complications were observed. As for the minor complications, one patient (1.6%) developed hematuria and four patients (6.5%) had fever. CONCLUSION: The described fluoroscopy-free RIRS procedure can be performed effectively and safely in patients diagnosed with renal calculi, by endourologists.
