Abstract
BACKGROUND Although prostate cancer is a prevalent malignancy worldwide, its clinical presentation and management in the Middle East are not well-documented. This study aims to provide insights into the initial clinical presentation and management of prostate cancer in this region. METHODS A retrospective review was conducted on seven institutional databases from six Middle Eastern countries, including Türkiye, Lebanon, Iraq, Syria, Bahrain, and Jordan, to identify patients diagnosed with prostate cancer in 2021. Descriptive analysis was performed on the collected data to provide an overview of the demographic, clinical, and treatment variables. RESULTS A total of 1,136 patients were identified with a median age of 70 (range, 50-84). Most patients (78%) received their prostate cancer diagnosis after presenting with symptoms, as opposed to routine PSA screening. At the time of diagnosis, 35% of men had clinical T3 or T4 disease, 54% with Stage IV disease and 50% with Gleason score ≥ 8. Regarding treatment, 20% of non-metastatic and 22% of metastatic patients received no treatment. CONCLUSION Most men in this study sought prostate cancer evaluation due to symptoms and were subsequently diagnosed with advanced-stage disease, providing a foundation for future research aimed at understanding the underlying factors behind the observed trends and enabling informed interventions.

Abstract
PURPOSE/OBJECTIVE(S) Prostate cancer is one of the most common malignancies worldwide and the incidence rate continues to increase in the Middle East. In the absence of large well-established cancer registries, there are no data to reflect the disease stage at initial presentation and patterns of care in this region. In order to mitigate the disease burden and help stakeholders to implement new policies to improve patient outcomes, it is important to study the disease stage at the initial presentation. The purpose of this study was to evaluate the clinical presentation and treatment of prostate cancer in the Middle East. MATERIALS/METHODS We performed a retrospective review of 7 institutional databases in 6 Middle Eastern countries to identify patients diagnosed with prostate cancer in 2021. Demographic, clinical, and treatment variables were abstracted. Patients who missed ≥2 scheduled radiation therapy (RT) appointments (excluding planned treatment breaks) were deemed "noncompliant." RESULTS A total of 1,132 patients were identified with a median age was 70 (range, 50-84). Most of the patients (78%) were diagnosed after developing symptoms and not on routine PSA screening. Diagnostic workup was completed in 87% of the patient. At time of diagnosis, 35% men presented with clinical T3 or T4 disease, 53% with metastatic disease and 42% with Gleason score ≥ 8. Mean PSA at time of presentation was 84 ng/ml. Among the nonmetastatic patients, 23% underwent a prostatectomy, 48% received definitive RT with or without androgen deprivation therapy (ADT), 9% received ADT alone and 20% received no treatment. No brachytherapy was used. Hypofractionated RT was used in 49% patients and only 8% were deemed "noncompliant". Among the metastatic patients, 74% received ADT with or without additional systemic therapy, 25% had palliative RT and 22% received no treatment. CONCLUSION In this large cohort of prostate cancer patients in the Middle East, most men presented with symptoms and were found to have advanced-stage disease. However, substantial proportion of patients did not receive any treatment. Further interventions to optimize prostate cancer diagnosis and treatment in in the Middle East are urgently needed.

Abstract
PURPOSE This study was performed to evaluate the effect of ethanolic extract of Turkish propolis (EEP) on testicular ischemia/reperfusion (I/R) damage in rats in terms of biochemistry and histopathology, for the first time. METHODS A total of 18 male Sprague-Dawley rats were divided into three groups with six rats in each group: control, torsion/detorsion (T/D), and T/D+EEP (100mg/kg). Testicular torsion was performed by 720° rotating the left testicle in a clockwise direction. The duration of ischemia was 4h and orchiectomy was performed after 2h of detorsion. EEP was applied only once 30min before detorsion. Tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) levels were determined using colorimetric methods. Oxidative stress index (OSI) was calculated by proportioning tissue TOS and TAS values to each other. Tissue glutathione (GSH) and glutathione peroxidase (GPx) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In the T/D group, it was determined that statistically significant decreasing in TAS, GSH, GPx levels and Johnsen score, and increasing in TOS, OSI and MDA levels (p<0.05) compared with control group. EEP administration statistically significantly restored this I/R damage (p<0.05). CONCLUSION This is the first study to show that propolis prevent I/R-induced testicular damage through its antioxidant activity. More comprehensive studies are needed to see the underlying mechanisms.

Abstract
PURPOSE To investigate the possible protective role of syringic acid on torsion/detorsion-induced testicular injury using biochemical and histopathological approaches for the first time. METHODS A total of 24 rats were divided into 4 groups: sham control, torsion/detorsion, torsion/detorsion + syringic acid (50 mg/kg and 100 mg/kg). Tissue malondialdehyde, total oxidant status and total antioxidant status levels were determined using colorimetric methods. Tissue 8-hydroxy-2'-deoxyguanosine, superoxide dismutase, catalase, high mobility group box 1, nuclear factor kappa B protein 65, tumor necrosis factor-alpha, interleukin-6, myeloperoxidase, 78-kDa glucose-regulated protein, activating transcription factor-6, C/EBP homologous protein and caspase-3 levels were determined using commercial enzyme-linked immunosorbent assay kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS Compared with the control group, the levels of oxidative stress, inflammation, endoplasmic reticulum stress and apoptosis were significantly increased in the torsion/detorsion group (p < 0.05). Syringic acid administrations statistically significantly restored these damage in a dose dependent manner (p < 0.05). Moreover, it was found that the results of histological examinations supported the biochemical results to a statistically significant extent. CONCLUSION The overall results suggest that syringic acid emerges as a potential compound for the treatment of testicular torsion and may be subject to clinical trials.

Abstract
Abstract
Background
Testicular torsion is an important pediatric problem and ischemia/reperfusion injury (IRI) is involved in its etiopathogenesis. Vanillic acid (VA) is a phenolic acid has strong antioxidant properties. To our knowledge, the ability of VA to reduce testicular IRI has not been previously investigated. It was therefore aimed to evaluate whether VA had a beneficial effect against testicular IRI model in rats for the first time. Twenty-four rats were segregated into four groups: sham control, torsion/detorsion (T/D), T/D + VA (50 mg/kg and 100 mg/kg). The levels of testicular oxidative stress, inflammation, endoplasmic reticulum (ER) stress and apoptosis markers were determined using colorimetric methods. Hematoxylin–eosin staining method was used in the histopathological evaluation.
Results
Oxidative stress, inflammation, ER stress and apoptosis levels were significantly higher in testicular tissues of rats with only IRI model (p < 0.05). VA applications improved these injuries in a dose-dependent manner (p < 0.05). Moreover, it was found that the results of histological examinations supported the biochemical results to a statistically significant extent.
Conclusions
It was revealed that VA application can remove testicular IRI for the first time. This testicular protective efficacy of VA needs to be supported by more extensive preclinical studies.

Abstract
BACKROUND Testicular torsion (TT) is an urological emergency situation especially in adolescents and young men. The main pathophysiology of testicular torsion/detorsion (T/D) is ischemia-reperfusion (I/R) injury. I/R induces the production of reactive oxygen species (ROS) thought to play a critical role in tissue injury. Increasing evidence suggests that ER stress may play an important role in I/R-induced cell death. During ischemia, oxygen and glucose deprivation also causes abnormalities in protein folding processes. Antioxidants suppress oxidative stress directly as well as ER stress and thus gain importance in the treatment of pathologies associated with oxidative stress and ER stress, such as I/R damage. Chlorogenic acid (CGA) which is formed by the esterification of caffeic and quinic acids and is one of the most abundant phenolic acids in nature. There is also a growing body of studies reporting protective effects of CGA against I/R injury in different tissues, including intestinal, heart and brain. OBJECTIVE To investigate the effects of CGA on oxidative stress and ER stress in an experimental testicular I/R injury model. DESIGN Rats were divided into three groups: control, T/D, and T/D + CGA. In the T/D + CGA group, 100 mg/kg CGA was given intraperitoneally 30 min before detorsion. While tissue malondialdehyde (MDA) levels were determined manually using a colorimetric method, tissue superoxide dismutase (SOD), 78-kDa glucose regulatory protein (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP) levels were determined enzyme-linked immunosorbent assay (ELISA) kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In T/D group, tissue MDA, GRP78, ATF6 and CHOP levels were significantly higher than control group (p < 0.05). These increases were significantly reversed with CGA pre-treatment (p < 0.05). The histopathological Johnsen score was significantly lower in the T/D group compared to the control group, but the level of histopathological Johnsen score was significantly restored by CGA pre-treatment (p < 0.05). DISCUSSION The relationship between I/R injury and ER stress has been emphasized frequently in recent years. This study in which the effects of CGA on TT were examined for the first time, showed that CGA can inhibit I/R-induced testicular damage. CONCLUSION These results may provide a new insight into CGA and may form the first clinical theoretical basis for the possible use of CGA in the treatment of TT in the future. However, the real function of CGA in TT patients needs further investigation.

To evaluate the degree of oxidative stress, tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) levels were determined using colorimetric methods, while tissue superoxide dismutase (SOD) levels were determined using an ELISA kit. To evaluate the degree of ERS, tissue glucose regulatory protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP) levels were determined using ELISA kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In the T/D group, it is determined that statistically significant decreasing in the levels of TAS, SOD and Johnsen score, and increasing in TOS, MDA, GRP78, ATF6 and CHOP levels compared to control group (p < 0.05). CHS administration statistically significantly restored this T/D-induced damage (p < 0.05). CONCLUSION This is the first study to show that CHS prevent T/D-induced testicular damage through its ERS inhibitor activity.

To evaluate the degree of oxidative stress, tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) were determined using colorimetric methods, while tissue superoxide dismutase (SOD) levels were determined using ELISA kit. To evaluate the degree of ER stress, tissue glucose regulatory protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP) levels were determined using ELISA kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In the T/D group, it is determined that statistically significant decreasing in TAS, SOD levels and Johnsen score, and increasing in TOS, OSI, MDA, GRP78, ATF6 and CHOP levels (p < 0.001) compared with control group. ASX administration statistically significantly restored this T/D-induced damage (p < 0.01). CONCLUSION This is the first study to show that ASX prevent T/D-induced testicular damage through its antioxidant activity. More comprehensive studies are needed to see the underlying mechanisms.

Abstract
AIMS OF THE STUDY The aim of this study was to investigate the impact of testosterone deficiency on cognitive functions in metastatic prostate cancer patients receiving androgen deprivation therapy (ADT). METHODS In this multicentric prospective study, 65 metastatic prostate cancer patients were evaluated. Demographic and clinical data were recorded. Cognitive functions were assessed using the Symbol Digit Modalities Test, the California Verbal Learning Test Second Edition, the Brief Visuospatial Memory Test-Revised, and the Trail Making Test. Depressive symptoms were assessed using the Beck Depression Inventory. Cognitive functions and depressive symptoms were recorded before the androgen deprivation therapy and at the 3- and 6-month follow-ups. RESULTS At the basal cognitive assessment, the mean Symbol Digit Modalities Test, the California Verbal Learning Test Second Edition, the Brief Visuospatial Memory Test-Revised scores were 25.84 ± 17.54, 32.68 ± 10.60, and 17.63 ± 11.23, respectively, and the mean time for the Trail Making Test was 221.56 ± 92.44 seconds, and were similar at the 3-month, and 6-month controls (P > .05). The mean pretreatment, third and sixth month testosterone levels were 381.40 ± 157.53 ng/dL, 21.61 ± 9.09 ng/dL and 12.25 ± 6.45 ng/dL (P < .05), and the total PSA levels were 46.46 ± 37.83 ng/mL, 1.41 ± 3.31 ng/mL and 0.08 ± 0.14 ng/mL (P < .05), respectively. CONCLUSION The ADT in patients with metastatic prostate cancer does not affect patients' cognitive functions and depressive symptoms. However, further prospective randomised studies with higher cohorts and longer follow-up periods are needed.

Abstract
BACKGROUND Obesity and metabolic syndrome are growing health problems in western countries. Recently reported triglyseride-glucose (TyG) index is a reliable and accessible indicator of metabolic syndrome. TyG index could be used as a indicator of a prognostic risk factor for metabolic syndrome-related cancers. OBJECTIVES To investigate the prognostic role of TyG index on oncological outcomes in patients undergoing radical prostatectomy. DESIGN, SETTING AND PARTICIPANTS Data from 200 men who underwent radical prostatectomy were used. OUTCOME MEASUREMENTS AND STATSITICAL ANALYSE TyG was calculated based on TyG index = Ln [TG (mg/dL) FPG (mg/dL)/2] formula. Patients were divided into two groups according to the 8.55 level as cut-off value for TyG index. Laboratory results, oncological outcomes and survivals were comparised statistically between groups. RESULTS Mean ages of patients were 64.32 ± 6.1 years and median follow-up time was 61.6 ± 35 (range 4-140) month. Biochemical recurrens was observed in 42 (21%) patients. Positive correlation between TyG index, body mass index, waist circumference, prostate biopsy gleason score, clinical T stage, positive surgical margin, pathological T stage and biochemical recurrence were observed. There was no statistical significance in terms of survival between groups. CONCLUSION Association between TyG index and prostate cancer may facilitate to predict unfavorable prognostic factors of radical prostatectomy. Increased TyG index may use as a predictive marker of positive surgical margin status before radical prostatectomy, BCR, advanced cT and pT stages after radical prostatectomy or worse biopsy gleason score in clinical practice.

Abstract
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.

Abstract
We aimed to investigate the relationship between premature ejaculation and the age when men had been circumcised before adulthood. A total of 2,768 sexually active male patients aged between 18 and 65 years were included in this study. A multicentre study was conducted prospectively with the participation of 20 centres. A survey consisting of 12 questions prepared by the researchers, as well as the validated Turkish versions of the five-item Premature Ejaculation Diagnostic Tool, was administered to all participants. The study included 1,603 participants who met the inclusion criteria. There was no significant difference in the Premature Ejaculation Diagnostic Tool and self-reported ejaculation time between the participants who had been circumcised at different ages during childhood. Remembering circumcision experience with fear or anxiety did not increase the risk of sexual dysfunction compared to the participants who described their experience with happiness or with no particular emotion. There was no significant difference in Premature Ejaculation Diagnostic Tool scores or the self-reported ejaculation time of the participants circumcised at different ages. The age of childhood circumcision, having a fearful or anxious circumcision experience, does not affect the risk of premature ejaculation in adult life.

Abstract
OBJECTIVES There is no standardised and up-to-date education model for urology residents in our country. We aimed to describe our National E-learning education model for urology residents. METHODOLOGY The ERTP working group; consisting of urologists was established by the Society of Urological Surgery to create E-learning model and curriculum in April 2018. Learning objectives were set up in order to determine and standardise the contents of the presentations. In accordance with the Bloom Taxonomy, 834 learning objectives were created for a total of 90 lectures (18 lectures for each PGY year). Totally 90 videos were shot by specialised instructors and webcasts were prepared. Webcasts were posted at uropedia.com.tr, which is the web library of the Society of Urological Surgery. The satisfaction of residents and instructors was evaluated with feedbacks. An assessment of knowledge was measured with the multiple-choice exam. RESULTS A total of 43 centres and 250 urology residents were included in ERTP during the academic year 2018/2019. There were 93/55/43/34/25 urology residents at 1st/2nd/3rd/4th and 5th year of residency, respectively. Majority of the residents (99.1%) completed the ERTP. The overall satisfaction rate of residents and instructors were 4.29 and 4.67 (min: 1 so bad, max: 5 so good). An assessment exam was performed to urology residents at the end of the ERTP and the mean score was calculated as 57.99 points (min: 20, max: 82). CONCLUSION As a result of the COVID-19 pandemic, most of the educational programmes had to move online platforms. We used this reliable and easily accessible e-learning platform for the standardisation of training in urology on national basis. We aim to share this model with international residency training programmes.

Abstract
Primary renal angiosarcomas (AS) are uncommon tumors with poor prognosis. Aetiology is unknown but some unproven risk factors have been described. It is difficult to discriminate these masses from renal cell carcinomas or other renal masses with imaging modalities. Immunohistochemistry plays an important role in the diagnosis. Main treatment protocol for primary renal AS is still controversial and nephrectomy with chemotherapy and/or radiotherapy seems the only treatment option. We state a primary renal angiosarcoma case for its rareness and contribution to literature.

Abstract
We investigated the effects of ethyl pyruvate (EP) on oxidative and endoplasmic reticulum (ER) stress due to experimental testicular ischemia-reperfusion (I-R). Eighteen rats were divided into a control group, a torsion-detorsion (T-D) group and an EP group. For pretreatment of the EP group, 50 mg/kg EP was given intraperitoneally (i.p.) 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE) and 78-kDa glucose-regulated protein (GRP78) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Tissue total oxidant status (TOS) and total antioxidant status were determined using colorimetric methods. Histology of the tissues was evaluated using hematoxylin and eosin staining. In the T-D group, tissue 4-HNE, GRP78, TOS and oxidative stress index levels were significantly higher than for the control group. The increases were reduced significantly by EP pretreatment. Our findings suggest that EP can inhibit I-R induced testicular injury by suppressing oxidative and ER stress. EP may be a useful adjunctive treatment for surgical repair in humans.

Abstract
BACKGROUND In animal models, endoplasmic reticulum (ER) stress has been reported to play a vital role in mediating ischemia/reperfusion (I/R) injury in certain organs, such as brain, liver, and intestine. However, there are a limited number of studies examining the relationship between ER stress and torsion and detorsion (T/D)-induced testicular injury. OBJECTIVE To investigate the effects of N-acetylcysteine (NAC) on ER-stress and apoptosis in an experimental testicular I/R injury model. DESIGN A non-blinded experimental study with three arms. Rats were divided into three groups: control group, T/D group, and NAC group. In the pretreatment of the NAC group, 20 mg/kg NAC was given intraperitoneally 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE), 78-kDa glucose-regulated protein (GRP78), and activating transcription factor 6 (ATF6) levels were determined using enzyme-linked immunosorbent assay. The apoptosis levels were evaluated using terminal deoxynucleotide transferase-mediated dUTP nick-end label assay. RESULTS In T/D group, tissue 4-HNE, GRP78, ATF6, and apoptotic index levels were significantly higher than control group. These increases were significantly reversed with NAC pretreatment. DISCUSSION There are some potential drugs that have been shown to reduce ER stress in the experimental ischemia model, and it is questioned that these drug candidates can be used as a therapeutic agent in the treatment of ischemic diseases in the near future. This study was not without limitations. First, the authors applied NAC only 20 mg/kg. In a future study, a dose-dependent assay should be performed to assess the likelihood of an additional testicular protective effect. One limitation of this research is also that in vivo studies cannot be extrapolated to possible effect in clinics. More experiments therefore need to be conducted to extrapolate the study findings to humans. CONCLUSION The study results showed that, after testicular torsion (TT), the ER stress-related apoptotic pathway plays a pivotal role in testicular injury. Further studies of other experimental models of TT may prove that NAC is a useful agent as an adjunctive treatment in surgical repair in human cases.

Abstract
Purpose: This study investigated the antioxidant effects of whortleberry against cisplatin-induced nephrotoxicity in rats. Material and methods: This study included 48 female Sprague–Dawley rats weighing 263.68 ± 8.29 g. The rats were divided into the following six groups, with eight rats in each group: control, ethanol control, whortleberry control, cisplatin control, 16 mg/kg cisplatin +100 mg/kg whortleberry, and 16 mg/kg cisplatin +200 mg/kg whortleberry groups. Biochemical analysis was performed by measuring total oxidant status and total antioxidant status, histopathological analysis was performed by calculating proximal and distal tubule areas (μm2), and immunohistochemical analysis was performed by determining anti-Caspase-3 immunostaining. Differences among the groups were examined using one-way analysis of variance, and p < .05 was considered statistically significant. Results: Cisplatin treatment decreased the total antioxidant status and increased the total oxidant status and Caspase-3 level. Moreover, it resulted in the dilatation, vacuolization and loss of tubular epithelial cells; and glomerular degeneration and edema in the kidney tissues (p < .05). Treatment with 100 and 200 mg whortleberries increased the total antioxidant status; decreased the total oxidant status and Caspase-3 level and ameliorated distal and proximal tubule degeneration, glomerular degeneration and edema in the kidney tissues (p < .05). Conclusions: Our results indicate that the antioxidant effects of the whortleberry decrease cisplatin-associated nephrotoxicity.

Abstract
Purpose: Despite the nerve-sparing technique, many patients suffer from erectile dysfunction after radical prostatectomy (RP) due to cavernous nerve injury. The aim of this study was to evaluate dipyridamole as a potential treatment agent of post-radical prostatectomy erectile dysfunction. Material and methods: A total of 18 male Sprague-Dawley rats were randomized into three experimental Groups (SHAM+DMSO, BCNI+DMSO and BCNI+DIP). An animal model of bilateral cavernous nerve crush injury (BCNI) was established to mimic the partial nerve damage during nerve-sparing RP. After creating of BCNI, dimethyl sulphoxide (DMSO) was administered transperitoneally as a vehicle to SHAM+DMSO and BCNI+DMSO Groups. BCNI+DIP Group received dipyiridamole (10mg/kg/day) as a solution in DMSO for 15 days. Afterwards, rats were evaluated for in vivo erectile response to cavernous nerve stimulation. Penile tissues were also analyzed biochemically for transforming growth factor-β1 (TGF-β1) level. Penile corporal apoptosis was determined by TUNEL method. Results: Erectile response was decreased in rats with BCNI and there was no significant improvement with dipyridamole treatment. TGF-β1 levels were increased in rats with BCNI and decreased with dipyridamole treatment. Dipyridamole led to reduced penile apoptosis in rats with BCNI and there was no significant difference when compared to sham operated rats. Conclusions: Although fifteen-day dipyridamole treatment has failed to improve erectile function in rats with BCNI, the decline in both TGF-β1 levels and apoptotic indices with treatment may be helpful in protecting penile morphology after cavernous nerve injury.

Abstract
The use of ureteral stents has become a routine urological practice. There are many different complications with ureteral stent use. One rare complication is knotting, which can be a very difficult condition to treat. We report a case in which a complete knot was found in the proximal part of an indwelling ureteral stent with a proximal ureteral stone.
