Purpose: Current occupational recommendations limit fetal radiation dose to 1 mSv. With increased gender diversity in urology, understanding radiation exposure during pregnancy is crucial. The purpose of this study was to determine surgeon uterine radiation dose during percutaneous nephrolithotomy (PCNL) and compare effectiveness of several radiation reduction strategies in a cadaver model. Materials and Methods: Two cadavers were used to simulate the surgeon and the patient in a PCNL model. An ion chamber was placed behind the surgeon's anterior uterine wall to measure the radiation dose. Three radiation reduction methods were compared: pulsed fluoroscopy (1, 4, 8, 15, 30 pulses per second [pps]), low-dose (LD) fluoroscopy, and surgeon shielding (none, 0.35-, 0.50-, 0.70-mm lead equivalents). The average radiation dose per second was recorded for 20 trials per combination. Assuming 5 minutes of fluoroscopy per PCNL, the number of cases required to exceed the fetal occupational limit was determined. Results: Decreasing pulse frequency from 30 to 1 pps reduced the dose by 96% (P <.001). The LD setting decreased the dose by 56% (P <.001). A 0.35-mm lead apron resulted in a 94% dose reduction (P <.001), and the 0.50- and 0.70-mm lead aprons further reduced the dose by 12% and 47%, respectively. In conventional fluoroscopy settings of automatic exposure control and at 30 pps, a surgeon could perform 12 PCNLs using no lead or 189 PCNLs using a 0.35-mm lead apron before reaching the 1-mSv limit. In addition to shielding, using 1 pps with LD fluoroscopy further decreased radiation exposure, allowing over 6000 cases to be performed with < 1 mSv uterine radiation exposure. Conclusions: Within the limitations of this cadaver study, these data support that high-volume pregnant surgeons using active radiation reduction techniques such as pulsed fluoroscopy, LD fluoroscopy, and appropriate shielding can maintain surgical volume with relatively low risk. Fetal dosimeter use with monthly monitoring is still encouraged to confirm safety throughout pregnancy. [ABSTRACT FROM AUTHOR]

Introduction and Objective: As part of the Endourological Society's (ES) initiative to continuously enhance the field of endourology, the second annual census was circulated after the World Congress of Endourology and Uro-Technology 2022 (WCET22). Methods: An anonymous survey was created using Qualtrics XM and was disseminated via email to all ES members (n = 1502) between October 4, 2022, and January 26, 2023. A total of 46 questions were included in the survey and covered different aspects, including demographics, practice patterns, satisfaction, impact of COVID-19, WCET22 attendance, and future opportunities. Results: A total of 404 (26.9%) ES members (91.8% male and 8.2% female), representing 63 different countries, participated in the survey. Fellowship-trained endourologists constituted 58.9% of respondents, and the most common practice setting was academic (55.2%). The most common practice scope was complex retrograde endoscopy (83.4%), followed by percutaneous nephrolithotomy (79.5%) and medical management of urolithiasis (72.5%). Work schedules were variable, with 51.1% working 40–60 hours/week and 35.3% working >60 hours/week. More than 80% were satisfied with t heir practice; however, 42.4% indicated that COVID-19 made satisfaction worse. Of the participants, 49.5% were satisfied with their compensation, and 7.3% plan to retire within the next 5 years. When asked about the future of endourology, 92.9% had a positive outlook. Of the respondents, only 36.8% attended WCET22, with the most chosen reason for attendance being an interest in learning new research and technology. For lack of attendance, the cost of travel and lodging was reported as a determining factor by 45.4%. Conclusion: These survey results report important trends within the field of endourology and demonstrate the robust outlook of ES members for the future. By demonstrating important practice patterns and member needs, this information can be used to improve the responsiveness of its members and to continually strengthen the ES. [ABSTRACT FROM AUTHOR]

Introduction: The thulium fiber laser (TFL) generates a focused beam, which can be transmitted to laser fibers with small core diameters and may facilitate in situ lower-pole lithotripsy. This study compares lithotripsy performance of the 150 and 200 µm TFL in a lower pole benchtop kidney model. Materials and Methods: Using a 3D model printed from an actual kidney, in situ laser lithotripsy was performed on 1 cm lower-pole BegoStones (calcium oxalate monohydrate consistency) using four different settings (all 20W) and two fiber sizes (150 and 200 µm). Procedure time, laser time, total pulse energy, and fiber stripping were compared between the two fibers using an ANOVA or independent t-test. Results: The 150 µm fiber at 0.2 J × 100 Hz had the shortest lasing and procedure time (17.3 and 18.5 minutes) and lowest total pulse energy (20.75 kJ) compared with other study arms (p < 0.001). Overall procedure time, lasing time, and total pulse energy were significantly different between the 8 settings (p < 0.001 for all). At higher frequency (100 and 200 Hz), lasing time was significantly faster compared with 20 and 50 Hz (19.9 vs 27.3 minutes; p < 0.001). Furthermore, the average total procedure time was shorter with 150 µm compared with 200 µm regardless of settings (23.2 vs 29.8 minutes; p < 0.001). Conclusion: The 150 µm fiber results in shorter procedure and lasing time at lower total energy levels during lower-pole in situ lithotripsy. Overall, the fastest setting was 0.2 J and 100 Hz with the 150 µm fiber. Smaller laser fibers can potentially allow more efficient in situ laser lithotripsy with better irrigation and visibility at higher deflection angles. [ABSTRACT FROM AUTHOR]

Introduction: Flat-panel detector C-arms (FCs) are reported to reduce radiation exposure and improve image quality compared with conventional image intensifier C-arms (CCs). The purpose of this study was to compare radiation exposure and image quality between three commonly used FCs. Materials and Methods: A cadaver model was placed in the prone position to simulate percutaneous nephrolithotomy. We compared the following three FCs: OEC Elite CFD from GE HealthCare, Zenition 70 from Philips, and Ziehm Vision RFD from Ziehm Imaging. To measure the radiation dose, optically stimulated luminescence dosimeters (OSLDs) were utilized during five 300-second trials, conducted under three settings: automatic exposure control (AEC), AEC with low dose (LD), and LD with the lowest pulse rate (LDLP). Ten blinded urologists evaluated the image quality. Data were statistically analyzed using the analysis of variance (ANOVA) and Tukey's B post hoc tests. Results: In the AEC setting, the Philips C-arm demonstrated lower ventral OSLD exposure (42,446 mrad) compared with both the GE (51,076 mrad) and Ziehm (83,178 mrad; p < 0.001) C-arms. Similarly, in the LD setting, the Philips C-arm resulted in less ventral OSLD exposure (25,926 mrad) than both the Ziehm (30,956 mrad) and GE (38,209 mrad; p < 0.001) C-arms. Meanwhile, in the LDLP setting, the Ziehm C-arm showed less ventral OSLD exposure (4019 mrad) than both the GE (7418 mrad) and Philips (8229 mrad; p < 0.001) C-arms. All three manufacturers received adequate image quality ratings at the AEC and LD settings. However, at LDLP, the Ziehm C-arm received inadequate ratings in 8% of images, whereas both the GE and Philips C-arms received 100% adequate ratings (p = 0.016). Conclusions: Radiation produced by flat-panel C-arms varies dramatically, with the highest exposure (Ziehm) being almost double the lowest (Philips) in AEC. Improved picture quality at the lowest settings may come at the cost of increased radiation dose. Surgeons should carefully select the machine and settings to minimize radiation exposure while still preserving the image quality. [ABSTRACT FROM AUTHOR]

Purpose: Sperm DNA fragmentation (SDF) is a functional sperm abnormality that can impact reproductive potential, for which four assays have been described in the recently published sixth edition of the WHO laboratory manual for the examination and processing of human semen. The purpose of this study was to examine the global practices related to the use of SDF assays and investigate the barriers and limitations that clinicians face in incorporating these tests into their practice. Materials and Methods: Clinicians managing male infertility were invited to complete an online survey on practices related to SDF diagnostic and treatment approaches. Their responses related to the technical aspects of SDF testing, current professional society guidelines, and the literature were used to generate expert recommendations via the Delphi method. Finally, challenges related to SDF that the clinicians encounter in their daily practice were captured. Results: The survey was completed by 436 reproductive clinicians. Overall, terminal deoxynucleotidyl transferase deoxyuridine triphosphate Nick-End Labeling (TUNEL) is the most commonly used assay chosen by 28.6%, followed by the sperm chromatin structure assay (24.1%), and the sperm chromatin dispersion (19.1%). The choice of the assay was largely influenced by availability (70% of respondents). A threshold of 30% was the most selected cut-off value for elevated SDF by 33.7% of clinicians. Of respondents, 53.6% recommend SDF testing after 3 to 5 days of abstinence. Although 75.3% believe SDF testing can provide an explanation for many unknown causes of infertility, the main limiting factors selected by respondents are a lack of professional society guideline recommendations (62.7%) and an absence of globally accepted references for SDF interpretation (50.3%). Conclusions: This study represents the largest global survey on the technical aspects of SDF testing as well as the barriers encountered by clinicians. Unified global recommendations regarding clinician implementation and standard laboratory interpretation of SDF testing are crucial. [ABSTRACT FROM AUTHOR]

Introduction: A flexible cystoscope is an indispensable tool for urologists, facilitating a variety of procedures in both the operating room and at bedside. Single-use cystoscopes offer benefits including accessibility and decreased burden for reprocessing. The aims of this study were to compare time efficiency and performance of single-use and reusable cystoscopes. Methods: Ten new Ambu® aScope™ 4 Cysto single-use and two Olympus CYF-5 reusable cystoscopes were compared in simulated bedside cystoscopy and benchtop testing. Ten urologists performed simulated cystoscopy using both cystoscopes in a randomized order. Times for supply-gathering, setup, cystoscopy, cleanup, and cumulative time were recorded, followed by a Likert feedback survey. For benchtop assessment, physical, optical, and functional specifications were assessed and compared between cystoscopes. Results: The single-use cystoscope demonstrated shorter supply-gathering, setup, cleanup, and cumulative times (824 vs 1231 seconds; p < 0.05) but a comparable cystoscopy time to the reusable cystoscope (202 vs 212 seconds; p = 0.32). The single-use cystoscope had a higher image resolution, but a narrower field of view. Upward deflection was greater for the single-use cystoscope (214.50° vs 199.45°; p < 0.01) but required greater force (2.5 × ). The working channel diameter and irrigation rate were greater in the reusable cystoscope. While the single-use cystoscope lacked tumor enhancing optical features, it had higher Likert scale scores for Time Efficiency and Overall Satisfaction. Conclusion: The single-use cystoscope demonstrates comparable benchtop performance and superior time efficiency compared to reusable cystoscopes. However, the reusable cystoscope has superior optical versatility and flow rate. Knowledge of these differences allows for optimal cystoscope selection based on procedure indication.

Sperm DNA fragmentation (SDF) is a molecular marker of sperm chromatin health. Elevated SDF is associated with male infertility, recurrent pregnancy loss, and failure of assisted reproductive technologies (ART). In 2021, the sixth edition of the World Health Organization (WHO) Manual for the Laboratory Examination and Processing of Human Semen has listed SDF as an extended test of semen that can be ordered under certain circumstances. However, the manual neither explained the indications for testing nor provided clear guidance on diagnostic thresholds. This article summarizes the current body of knowledge regarding clinical applications of SDF, including the appropriate population to test, methods of testing, and management strategies. Several etiologic factors and pathophysiologic mechanisms for SDF have been described including poor lifestyle habits, noxious exposures, and varicocele. Four SDF assays are included in the WHO manual and may be utilized based on resources and expertise. Strategies to lower SDF levels in infertile men include addressing underlying causes, supplementation with antioxidants, shorter abstinence periods, and use of testicular sperm for intracytoplasmic sperm injection. SDF testing can be implemented in the evaluation of infertile men and couples experiencing ART failure and appropriate management strategies can be offered to improve reproductive outcomes. There is vast potential for future research regarding the clinical utility of SDF in the evaluation and treatment of infertile couples. [ABSTRACT FROM AUTHOR]

Introduction and Objective: A variety of laser sources are available to treat bladder stones. The aim of this study was to compare time and cost efficiency of the thulium fiber laser (TFL) to four holmium lasers (HLs) with different powers or technologies, including MOSES™ during simulated cystolithotripsy. Materials and Methods: In a benchtop simulation of laser cystolithotripsy, 25 identical 4-cm BegoStones (calcium oxalate monohydrate consistency) were placed on a grid within a 3D-printed bladder model. Lasers were operated at maximal energy, using a 550 μm fiber. Lasers compared were as follows: 60 W TFL, 120 W HL with MOSES, and conventional 120, 100, and 30 W HLs. Five trials were performed for each laser with endpoints of laser time, total time, number of fiber strippings, and total energy. Cost-effectiveness was modeled using laser purchase price, fiber, and operating room (OR) time cost. ANOVA with Tukey's B post hoc was performed to compare outcomes. Spearman's test was used to assess correlation between laser power and procedure time. Results: The laser and total operating times were significantly different between the five systems (p < 0.001). The 120 W HL with MOSES was the fastest with 60.9 minutes of laser and 68.3 minutes of procedure times, while the 30 W HL was the slowest with 281.2 minutes of laser and 297.5 minutes of procedure times. The 60 W TFL was faster than the 30 W HL, but slower than the higher power HLs. Higher laser power was associated with shorter procedure time (Rs = −0.98; p = 0.002). When estimating cost per procedure, the MOSES HL was the cheapest, but had the highest purchase cost. The TFL was not cost-effective for large bladder stones compared with the 100 W HL. Conclusions: When treating large bladder stones, total laser power was highly correlated with laser and procedure times and the TFL was limited by its total power. The most cost-effective laser for use will depend on the case volume. [ABSTRACT FROM AUTHOR]

Purpose: Sperm DNA fragmentation (SDF) has been associated with male infertility and poor outcomes of assisted reproductive technology (ART). The purpose of this study was to investigate global practices related to the management of elevated SDF in infertile men, summarize the relevant professional society recommendations, and provide expert recommendations for managing this condition. Materials and Methods: An online global survey on clinical practices related to SDF was disseminated to reproductive clinicians, according to the CHERRIES checklist criteria. Management protocols for various conditions associated with SDF were captured and compared to the relevant recommendations in professional society guidelines and the appropriate available evidence. Expert recommendations and consensus on the management of infertile men with elevated SDF were then formulated and adapted using the Delphi method. Results: A total of 436 experts from 55 different countries submitted responses. As an initial approach, 79.1% of reproductive experts recommend lifestyle modifications for infertile men with elevated SDF, and 76.9% prescribe empiric antioxidants. Regarding antioxidant duration, 39.3% recommend 4–6 months and 38.1% recommend 3 months. For men with unexplained or idiopathic infertility, and couples experiencing recurrent miscarriages associated with elevated SDF, most respondents refer to ART 6 months after failure of conservative and empiric medical management. Infertile men with clinical varicocele, normal conventional semen parameters, and elevated SDF are offered varicocele repair immediately after diagnosis by 31.4%, and after failure of antioxidants and conservative measures by 40.9%. Sperm selection techniques and testicular sperm extraction are also management options for couples undergoing ART. For most questions, heterogenous practices were demonstrated. Conclusions: This paper presents the results of a large global survey on the management of infertile men with elevated SDF and reveals a lack of consensus among clinicians. Furthermore, it demonstrates the scarcity of professional society guidelines in this regard and attempts to highlight the relevant evidence. Expert recommendations are proposed to help guide clinicians. [ABSTRACT FROM AUTHOR]

Background: Several studies have reported on the safety and feasibility of percutaneous nephrolithotomy (PCNL) under local anesthesia (LA). The aim of this systematic review is to assess the perioperative outcomes of PCNL under LA. Methods: Three electronic databases, including MEDLINE, EMBASE, and Web of Science, were searched for relevant English-language studies published from January 1980 to March 2023. The systematic review has been performed according to the Cochrane style and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. The primary outcomes include stone-free rate (SFR) and conversion to general anesthesia (GA). Secondary outcomes include postoperative complications. Results: Of 301 articles that were extracted, 42 full-text articles were selected, of which 36 were excluded, yielding a total of 6 articles in our results. A total of 3646 patients were included in this review. The SFR of PCNL under LA ranged between 69.9% and 93.3%. PCNL under LA was not tolerated by 19 (0.5%) patients: 6 patients had conversion to general anesthesia, 2 had conversion to epidural anesthesia, and 11 had their procedure terminated. The overall complication rates varied from 4.8% to 21% across studies. Grade I–II complications were reported in 2.4%–16.7% of cases, while grade III–IV complications were encountered in 0.5%–5% of patients. Conclusions: In this review, we found a few studies that examined the outcomes of PCNL under LA, which highlight the feasibility and safety of PCNL under LA and the low conversion rate to GA.

Purpose: Sperm DNA fragmentation (SDF) testing was recently added to the sixth edition of the World Health Organization laboratory manual for the examination and processing of human semen. Many conditions and risk factors have been associated with elevated SDF; therefore, it is important to identify the population of infertile men who might benefit from this test. The purpose of this study was to investigate global practices related to indications for SDF testing, compare the relevant professional society guideline recommendations, and provide expert recommendations. Materials and Methods: Clinicians managing male infertility were invited to take part in a global online survey on SDF clinical practices. This was conducted following the CHERRIES checklist criteria. The responses were compared to professional society guideline recommendations related to SDF and the appropriate available evidence. Expert recommendations on indications for SDF testing were then formulated, and the Delphi method was used to reach consensus. Results: The survey was completed by 436 experts from 55 countries. Almost 75% of respondents test for SDF in all or some men with unexplained or idiopathic infertility, 39% order it routinely in the work-up of recurrent pregnancy loss (RPL), and 62.2% investigate SDF in smokers. While 47% of reproductive urologists test SDF to support the decision for varicocele repair surgery when conventional semen parameters are normal, significantly fewer general urologists (23%; p=0.008) do the same. Nearly 70% would assess SDF before assisted reproductive technologies (ART), either always or for certain conditions. Recurrent ART failure is a common indication for SDF testing. Very few society recommendations were found regarding SDF testing. Conclusions: This article presents the largest global survey on the indications for SDF testing in infertile men, and demonstrates diverse practices. Furthermore, it highlights the paucity of professional society guideline recommendations. Expert recommendations are proposed to help guide clinicians. [ABSTRACT FROM AUTHOR]

Objectives: The incidence of bladder cancer in the Middle East is increasing. Nevertheless, data on the young population with urothelial carcinoma (UC) of the urinary bladder in this region is scarce. Therefore, we evaluated clinical and tumor characteristics, in addition to treatment details in patients younger than 45 years old. Methodology: We reviewed all patients presenting with UC of the urinary bladder from July 2006 to December 2019. Clinical characteristics including demographics, stage at presentation, and treatment outcomes were extracted. Results: Out of 1272 new cases of bladder cancer, a total of 112 (8.8%) patients were ≤45 years old. Seven patients (6%) had nonurothelial histology and were excluded from the study. The remaining 105 eligible patients with UC had a median age at presentation of 41 years (35-43). Ninety-three patients (88.6%) were males. Tumor stage at presentation: nonmuscle invasive disease (Ta-T1), locally advanced muscle-invasive bladder cancer (MIBC) (T2-3), and metastatic disease were 84.7%, 2.8%, and 12.5%, respectively. All patients with MIBC received neoadjuvant cisplatin-based chemotherapy. Radical cystectomy was performed in 8 (7.6%) cases; three patients with MIBC and five with high-volume non-MIBC. Neobladder reconstruction was done in six patients. A total of 13 patients with metastatic disease (93%) received palliative chemotherapy (gemcitabine/cisplatin), and one (7%) was a candidate for best supportive care only. Conclusion: Bladder cancer is relatively rare in the young population, although the incidence at our region is higher than other reports in the literature. Most patients present with early disease. Early diagnosis and multidisciplinary approach are paramount for the management of these patients. [ABSTRACT FROM AUTHOR]

Background and Aim. The chronicity of type 1 diabetes (T1D) and the demanding nature of care needed to maintain adequate glycemic control expose adolescents with T1D to various psychosocial disorders including depression. We aimed to study the frequency and risk factors of depressive symptoms in adolescents with T1D in Jordan. Methods. The study was conducted by distributing the Center for Epidemiological Studies Depression Scale for Children (CES-DC) to adolescents with T1D seen at Jordan University Hospital between February 2019 and February 2020. Demographic, clinical, and socioeconomic data were collected using electronic clinical charts. Possible predictors of depression were assessed using logistic regression analysis. Results. A total of 108 children were enrolled in the study with mean age of 13.7 ± 2.3 years. Fifty-eight children (53.7%) had a CES depression score less than 15, and 50 children (46.3%) had a depression score of 15 or more. The number of diabetes-related hospital admissions and the frequency of self-monitoring of blood glucose (SMBG) were significantly different between the two groups. In the multivariable analysis, both gender and SMBG frequency were statistically significant. Girls were more likely to have a depression score ≥ 15 (OR = 3.41 , p = 0.025) than boys. Patients who were rarely testing blood glucose levels were more likely to have a depression score ≥ 15 compared to those who were testing regularly (OR = 36.57 , p = 0.002). Conclusion. The prevalence of depressive symptoms is relatively high in adolescents with T1D, especially in those living in developing countries. Longer diabetes duration, higher glycated hemoglobin level, and less frequent blood glucose monitoring are associated with higher depression scores. [ABSTRACT FROM AUTHOR]

Purpose: Seminal oxidative stress (OS) is a recognized factor potentially associated with male infertility, but the efficacy of antioxidant (AOX) therapy is controversial and there is no consensus on its utility. Primary outcomes of this study were to investigate the effect of AOX on spontaneous clinical pregnancy, live birth and miscarriage rates in male infertile patients. Secondary outcomes were conventional semen parameters, sperm DNA fragmentation (SDF) and seminal OS. Materials and Methods: Literature search was performed using Scopus, PubMed, Ovid, Embase, and Cochrane databases. Only randomized controlled trials (RCTs) were included and the meta-analysis was conducted according to PRISMA guidelines. Results: We assessed for eligibility 1,307 abstracts, and 45 RCTs were finally included, for a total of 4,332 infertile patients. We found a significantly higher pregnancy rate in patients treated with AOX compared to placebo-treated or untreated controls, without significant inter-study heterogeneity. No effects on live-birth or miscarriage rates were observed in four studies. A significantly higher sperm concentration, sperm progressive motility, sperm total motility, and normal sperm morphology was found in patients compared to controls. We found no effect on SDF in analysis of three eligible studies. Seminal levels of total antioxidant capacity were significantly higher, while seminal malondialdehyde acid was significantly lower in patients than controls. These results did not change after exclusion of studies performed following varicocele repair. Conclusions: The present analysis upgrades the level of evidence favoring a recommendation for using AOX in male infertility to improve the spontaneous pregnancy rate and the conventional sperm parameters. The failure to demonstrate an increase in live-birth rate, despite an increase in pregnancy rates, is due to the very few RCTs specifically assessing the impact of AOX on live-birth rate. Therefore, further RCTs assessing the impact of AOX on live-birth rate and miscarriage rate, and SDF will be helpful. [ABSTRACT FROM AUTHOR]

Purpose: Azoospermia is defined as the absence of spermatozoa in the pellet of a centrifuged semen sample. In fact, when a basic semen analysis fails to detect sperm in the ejaculate, there is still the possibility of detecting rare sperm after centrifugation of the sample and examination of the pellet. In this study, we assessed the role of Cytospin centrifugation in combination with the nuclear fast picroindigocarmine (NF-PIC) staining in identifying sperm in azoospermic samples. Materials and Methods: Semen samples of 251 men diagnosed as having azoospermia after standard examination were further analyzed by Cytospin centrifugation in combination with NF-PIC staining. Results: Sperm were detected in 60 men (23.9%), thus changing their diagnosis to cryptozoospermia. Conclusions: By identifying sperm in the semen of men who were thought to have total azoospermia, the Cytospin NF-PIC test can alter the diagnosis and further treatment of these men.

Antisperm antibodies (ASA), as a cause of male infertility, have been detected in infertile males as early as 1954. Multiple causes of ASA production have been identified, and they are due to an abnormal exposure of mature germ cells to the immune system. ASA testing (with mixed anti-globulin reaction, and immunobead binding test) was described in the WHO manual 5th edition and is most recently listed among the extended semen tests in the WHO manual 6th edition. The relationship between ASA and infertility is somewhat complex. The presence of sperm agglutination, while insufficient to diagnose immunological infertility, may indicate the presence of ASA. However, ASA can also be present in the absence of any sperm agglutination. The andrological management of ASA depends on the etiology and individual practices of clinicians. In this article, we provide a comprehensive review of the causes of ASA production, its role in immunological male infertility, clinical indications of ASA testing, and the available therapeutic options. We also provide the details of laboratory procedures for assessment of ASA together with important measures for quality control. Additionally, laboratory and clinical scenarios are presented to guide the reader in the management of ASA and immunological male infertility. Furthermore, we report the results of a recent worldwide survey, conducted to gather information about clinical practices in the management of immunological male infertility. [ABSTRACT FROM AUTHOR]

Tocreate and validate a translated Arabic version of the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP), a validated patient-reported outcome (PRO) widely used for assessing the quality of life in patients with prostate cancer (PCa). Using the established protocol as defined by the Professional Society for the Health Economics and Outcomes Research (ISPOR) for translating patient care questionnaires, a harmonised translated Arabic version of EPIC-CP was created. The questionnaire was tested in native Arabic speakers from four different Arabic countries (Saudi Arabia, United Arab Emirates, Jordan, and Kuwait). Cronbach's alpha and interclass coefficient correlation (ICC) analyses were used to test the internal consistency and test–retest reliability, respectively. In addition, PCa characteristics were collected for participants. In total, 168 patients with PCa participated in the study (39 from Saudi Arabia, 23 from United Arab Emirates, 65 from Jordan, and 41 from Kuwait). In all, 52 (31%) participants repeated the questionnaire for test–retest reliability analysis. The median (interquartile range [IQR]) age of patients included in the study was 66 (61–71) years. The median (IQR) PSA level was 9.8 (6–19) ng/mL. Most patients had Grade Group 2 PCa at diagnosis (31%), clinical stage cT1 (42%), managed primarily by urology (79%), and the primary treatment was radical prostatectomy (71%). The total Cronbach's alpha coefficient was 0.84 demonstrating an acceptable internal consistency. The total ICC was also acceptable at 0.64. The Arabic version of the EPIC-CP is a reliable and valid tool for assessing health-related quality of life for Arabic patients with PCa. [ABSTRACT FROM AUTHOR]

Sperm vitality testing is a basic semen examination that has been described in the World Health Organization (WHO) Laboratory Manual for the Examination and Processing of Human Semen from its primary edition, 40 years ago. Several methods can be used to test sperm vitality, such as the eosin-nigrosin (E-N) stain or the hypoosmotic swelling (HOS) test. In the 6th (2021) edition of the WHO Laboratory Manual, sperm vitality assessment is mainly recommended if the total motility is less than 40%. Hence, a motile spermatozoon is considered alive, however, in certain conditions an immotile spermatozoon can also be alive. Therefore, the differentiation between asthenozoospermia (pathological decrease in sperm motility) and necrozoospermia (pathological decrease in sperm vitality) is important in directing further investigation and management of infertile patients. The causes leading to necrozoospermia are diverse and can either be local or general, testicular or extra-testicular. The andrological management of necrozoospermia depends on its etiology. However, there is no standardized treatment available presently and practice varies among clinicians. In this study, we report the results of a global survey to understand current practices regarding the physician order of sperm vitality tests as well as the management practices for necrozoospermia. Laboratory and clinical scenarios are presented to guide the reader in the management of necrozoospermia with the overall objective of establishing a benchmark ranging from the diagnosis of necrozoospermia by sperm vitality testing to its clinical management.

Sperm DNA fragmentation (SDF) is implicated in male infertility and adverse reproductive outcomes. With the publication of many studies regarding the etiologies and contributors to SDF, as well as the effects of SDF, guidelines are necessary to aid clinicians in the application of SDF for male fertility evaluation. Two recent clinical practice guidelines were published by Agarwal et al and Esteves et al. In this article, we have evaluated and compared both guidelines. We have found fairly similar recommendations between the two guidelines and have also highlighted the differences between them. Finally, we have summarized and combined the best practice recommendations from both guidelines. [ABSTRACT FROM AUTHOR]

The editorial comment discusses a study on radiation-free retrograde intrarenal surgery (RIRS) for the management of renal stones. The study found that radiation-free RIRS had similar success rates, operative times, and complications compared to standard RIRS. The authors acknowledge that while zero fluoroscopy is achievable, the safety and outcome of the surgery should take precedence. They suggest strategies for minimizing radiation during ureteroscopy, such as distance, shielding, visual and tactile feedback, and low-dose fluoroscopy settings. The authors conclude that radiation-free techniques can be safe and effective, but when not feasible, urologists should minimize radiation risks using the ALARA principle (as low as reasonably achievable).
