A cost outcome study of varicocoele embolisation and future pregnancy in an Australian public hospital setting.

INTRODUCTION: Varicocoele is commonly encountered in males with infertility. Studies have shown that varicocoele repair (surgery or embolisation) can improve the rate of subsequent pregnancy. In Australia, there have been no studies assessing the cost of varicocoele embolisation and current practice is based on international data. This study aimed to assess the cost of varicocoele embolisation and estimate the treatment cost per pregnancy. METHODS: Retrospective cost-outcome study of patients treated by embolisation between January 2018 and 2023. A bottom-up approach was used to calculate procedure costs whereas a top-down approach was used to calculate costs for all other patient services, including direct and indirect costs. To calculate cost per pregnancy, costs were adjusted according to existing published data on the rate of pregnancy after embolisation. RESULTS: Costing data from 18 patients were included, of median age 33.5 years (range 26-60) and median varicocoele grade 2.5 (range 1-3). All patients had unilateral treatment, most commonly via right internal jugular (16 patients, 89%) and using a 0.035″ system (17 patients, 94%). The median cost for the entire treatment including procedural, non-procedural, ward and peri-procedural costs was AUD$2208.10 (USD$1405 or EUR€1314), range AUD$1691-7051. The projected cost to the healthcare system per pregnancy was AUD$5387 (USD$3429 or EUR€3207). CONCLUSION: Total varicocoele embolisation cost and the cost per-pregnancy were lower than for both embolisation and surgical repair in existing international studies. Patients undergoing varicocoele treatment should have the option to access an interventional radiologist to realise the benefits of this low-cost pinhole procedure.

Retrograde sclerotherapy of male varicocele with veno-venous shunts - incidence and management: a single-centre experience.

OBJECTIVES: The aim of our study is to compare the incidence of veno-venous shunts in male varicocele and evaluate the possibility to exclude them with manual compression or/and scrotal ligation in order to carry out the procedure of retrograde sclero-embolization. METHODS: In our retrospective study, all patients undergone retrograde sclerotherapy for varicocele in our Interventional Radiology Unit in the last four years were evaluated. Collaterals toward other venous shunts were identified and how many and which patients would be able to complete the procedure safely were considered. RESULTS: Of the 91 patients, as many as 22 (i.e., 24.17%) patients presented anatomical variants, consisting on shunting into left iliac vein (9 [9.89%]), lumbar left veins (3 [3.29%]), right iliac vein (1 [1.09%]), both iliac veins (1 [1.09%]), left femoral vein (1 [1.09%]) or a more proximal portion of the ISV itself without shunting (3 [3.29%]). Patients with duplication could benefit from a more distal injection in order to prevent back-flow; of the 19 left, nine successfully underwent sclerotherapy with manual compression or/and scrotal ligation, whereas in 10 flow through the collaterals could not be interrupted and patients were demanded for surgery. CONCLUSIONS: Many patients with abnormal communications between the internal spermatic vein and the iliac veins (that is, shunts towards the iliac veins) may as well undergo retrograde sclerotherapy safely if compression/ligation is applied. ADVANCES IN KNOWLEDGE: No large previous study highlighted the impact of veno-venous shunts in technical feasibility of retrograde sclerotherapy of varicocele.

Predictors of microsurgical varicocelectomy efficacy in male infertility treatment: critical assessment and systematization.

In this review, we tried to systematize all the evidence (from PubMed [MEDLINE], Scopus, Cochrane Library, EBSCO, Embase, and Google Scholar) from 1993 to 2021 on the predictors of microsurgical varicocelectomy efficacy in male infertility treatment. Regarding the outcomes of varicocele repair, we considered semen improvement and pregnancy and analyzed them separately. Based on the 2011 Oxford CEBM Levels of Evidence, we assigned a score to each trial that studied the role of the predictor. We systematized the studied predictors based on the total points, which were, in turn, calculated based on the number and quality of studies that confirmed or rejected the studied predictor as significant, into three levels of significance: predictors of high, moderate, and low clinical significance. Preoperative total motile sperm count (TMSC) coupled with sperm concentration can be a significant predictor of semen improvement and pregnancy after varicocelectomy. In addition, for semen improvement alone, scrotal Doppler ultrasound (DUS) parameters, sperm DNA fragmentation index (DFI), and bilateral varicocelectomy are reliable predictors of microsurgical varicocelectomy efficacy.

The Assessment of TikTok as a Source of Quality Health Information on Varicoceles.

OBJECTIVE: To evaluate the quality of varicocele information on TikTok, a popular video platform that adolescent patients are now turning to as a source of medical information before visiting a doctor. METHODS: Using the key word "varicocele," we retrieved the top 225 videos listed on TikTok in May 2022. We extracted general video and engagement data. Video information was coded and analyzed for the completeness of different types of content (definition, symptoms, evaluation, management, and outcomes). The quality of consumer health information was rated using the DISCERN instrument. RESULTS: Thirty-six videos met inclusion criteria; 17 were created by general users, 16 by healthcare professionals or systems (2 by urologists), and 3 by scientific communities. Healthcare professionals had more views than non-healthcare (P = .05). The quality of health information using the DISCERN instrument was "poor" from health care professional videos and "very poor" from non-health care professionals. However, the quality of information provided by healthcare professionals was statistically better than that of non-healthcare (P< .05). Video content mainly focused on symptoms: 50% of videos from healthcare providers had some or extensive content and 41% of non-healthcare had some content. 23% of videos had misinformation. CONCLUSION: The overall quality of information for varicoceles on TikTok is not acceptable and does not meet patient needs. It is imperative that urologists create robust, accurate content, and partner with these platforms to connect users with higher quality information. TikTok users should also be mindful that information may not be medically accurate.

Dynamic contrast-enhanced MRI in the assessment of testicular perfusion in infertile men with clinical varicocele.

BACKGROUND: Varicocele represents the most common correctable cause of male infertility. The presence of non-invasive imaging parameters providing evidence as to which patients with varicocele are at risk for infertility would be important. PURPOSE: To explore the role of dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) using semi-quantitative parameters in the assessment of testicular perfusion in infertile men with clinical varicocele. MATERIAL AND METHODS: The study cohort included 11 infertile men with clinical varicocele and six controls, with prior paternity. Subtraction DCE-MRI was performed after gadolinium administration, using a three-dimensional fast field-echo sequence. Time-signal intensity curves were created and semi-quantitative parameters were calculated. The independent samples t-test was used to compare basic T1 perfusion parameters between infertile testes with clinical varicocele and normal testes. Logistic regression analysis was performed to assess the most significant predictor of the diagnosis of clinical varicocele. RESULTS: Both testes with clinical varicocele and normal testes enhanced moderately and homogeneously, with a linear increase of enhancement throughout the examination. Higher mean values of maximum enhancement (P = 0.026), maximum relative enhancement (P = 0.024), and wash-in rate (P = 0.013) were detected in the testes of infertile men with clinical varicocele, compared to the normal population. The wash-in rate proved the most significant predictor of the diagnosis of clinical varicocele (P = 0.013). CONCLUSION: DCE-MRI may provide a valuable insight into the testicular perfusion of infertile men with clinical varicocele. The wash-in rate proved a strong and independent predictor of the diagnosis of clinical varicocele.

Varicocele at High Altitude; Venous Outflow Restriction by Hypobaric Hypoxia.

BACKGROUND: Testicular aches have been reported to occur on exposure to high altitude (HA). As a painful expression of venous congestion at the pampiniform plexus, varicocele (VC) might be a consequence of cardiovascular adjustments at HA. Chile's National Social Security Regulatory Body (SUSESO) emphasized evaluating this condition in the running follow-up study "Health effects of exposure to chronic intermittent hypoxia in Chilean mining workers." OBJECTIVES: This study aimed at investigating the prevalence of VC in a population usually shifting between sea level and HA, thereby intermittently being exposed to hypobaric hypoxia. METHODOLOGY: Miners (n=492) agreed to be examined at their working place by a physician, in the context of a general health survey, for the presence of palpable VC, either visible or not. Among them was a group exposed to low altitude (LA) <2,400 m; n=123; another one exposed to moderate high altitude (MHA) working 3,050 m; n=70, and a third one exposed to very high altitude (VHA) >3,900 m, n=165. The Chi2 test and Kruskal-Wallis test were used for the descriptive analyses, and logistic regression was applied to evaluate the association of VC with exposure to HA. The Ethics Committee for Research in Human Beings, Faculty of Medicine, University of Chile, approved this project. RESULTS: VC prevalence (grades 2 and 3) was found to be 10% at LA, 4.1% at MHA, and 16.7% at VHA (p≤0.05). Hemoglobin oxygen saturation (SaO2) was lower, and hemoglobin concentrations were higher in workers with high-grade VC at VHA compared to LA and MHA (Wilcoxon tests, p<0.001). Odds ratios (OR) for the association of VC with HA were 3.7 (95%CI: 1.26 to 12.3) and 4.06 (95%CI: 1.73 to 11.2) for MHA and VHA, respectively. CONCLUSION: Association of VC with HA, a clinically relevant finding, may be related to blood volume centralization mediated by hypobaric hypoxia.

Varicocoele embolization with sclerosing agents leads to lower radiation exposure and procedural costs than coils: Data from a real-life before and after study.

OBJECTIVES: To investigate clinical outcomes, radiation exposure and procedural costs associated with percutaneous varicocoele embolization using coils and sclerosing agents (SAs) in a cohort of young-adult men. MATERIALS AND METHODS: Data from consecutive men treated with percutaneous varicocoele embolization using coils and SA between 2017 and 2021 were analyzed. The allocation was based on a change of policy occurred in June 2020 with the substitution of coils with SA (before and after study). Semen analysis values were based on 2010 WHO reference criteria. Anatomic variants of gonadal veins were categorized according to Jargiello et al. Intraoperative radiation dose and procedural costs were collected for each patient. Descriptive statistics and linear regression models were used to describe the association between clinical parameters with procedural costs and radiation exposure. RESULTS: One hundred sixteen men were included, of whom 76 (65.5%) received coils, and 40 (34.5%) received SA. Baseline characteristics of the two study groups did not differ. A type 3 Jargiello anatomic variation of left gonadal vein was found in 45.7% of cases. Radiation dose was lower in the SA group as compared to the coils one (13.2 [7-43] vs. 19.8 [12-57] Gy/cm2 ; p < 0.001). Similarly, procedural costs were lower for the SA group (169.6 [169-199] € vs. 642.5 [561-775] €; p < 0.001). At follow-up, pain and sperm variables significantly improved in both groups (p < 0.01), without differences among the embolic materials. Linear regression model revealed that coils use was associated with higher radiation exposure (beta 8.8, p = 0.02) than SA after accounting for anatomic variation of gonadal vein, body mass index, and vascular access. CONCLUSIONS: SA and coils for varicocoele embolization are equally safe and effective. The use of SA was associated with lower radiation exposure and procedural costs than coils. These results should be considered in terms of public health cost and patient's safety.

Assessment of seminal cystatin C levels in infertile men with varicocele: A preliminary study.

Varicocele has been raised as a contributor to male infertility supported by the improvement of sperm parameters after varicocelectomy. Cystatin C (Cys C) has been linked to several cellular changes that are common in male infertility cases associated with varicocele such as apoptosis and autophagy. This preliminary study aimed to assess the seminal levels of Cys C in infertile oligoasthenoteratozoospermic (OAT) men associated with varicocele that have been shown to have spermatic vein vasodilation and active death pathway. Overall, 60 men were investigated being divided into two equivalent groups-infertile OAT men with varicocele who underwent varicocelectomy and healthy fertile men as a control group. These men were subjected to history taking, clinical examination, semen analysis and assessment of seminal Cys C pre and 6 months post-varicocelectomy. The results showed a significant increase of seminal Cys C in infertile OAT men with varicocele than the fertile control (55.57 ± 25.6 ng/ml versus 10.78 ± 1.88 ng/ml, p = .001). Seminal Cys C was a significantly decreased post-operative than its pre-operative level (34.69 ± 14.02 versus 55.57 ± 25.6 ng/ml, p = .01). These results show a potential role of Cys C in varicocele-induced infertility.

Assessment of MUSASHI 1 and MUSASHI 2 expression in spermatozoa and testicular tissue.

MUSASHI (MSI) family plays the main role in the spermatogenesis process. The purpose of this study was the assessment of sperm MSI1 and MSI2, and sperm functional tests in infertile men (n = 30) with varicocele and fertile men (n = 30). Furthermore, MSI1 and MSI2 proteins were assessed in testicular tissue of azoospermic men (n = 9) as well as epididymal spermatozoa and testis of mice. Expression of MSI1 and MSI2 was assessed at RNA and protein levels in human spermatozoa. Sperm concentration and motility were significantly lower, while abnormal sperm morphology, lipid peroxidation, DNA fragmentation and protamine deficiency were significantly higher in men with varicocele compared to fertile individuals. Any significant difference was not observed in the expression of MSI1 and MSI2 mRNA between the two groups. Unlike MSI1 protein that was not detectable in humans, the relative expression of MSI2 protein was similar in varicocele and fertile individuals. The expression level of both Msi1 and Msi2 proteins was also observable in mouse spermatozoa. No significant relationship was observed between sperm functional parameters with expression of these genes. The data of this study demonstrated that although MSI1 and MSI2 play important roles during spermatogenesis, their relative expression in spermatozoa was not affected by varicocele.

Adolescent Varicocelectomy: Success at What Cost? Clinical Outcome and Cost Comparison of Surgical Ligation and Percutaneous Embolization.

Objectives: Evaluate clinical outcome, recurrence, morbidity, and cost associated with laparoscopic surgical ligation versus percutaneous embolization of adolescent varicocele. We hypothesize that both approaches are similar in outcomes, complications, and cost. Materials and Methods: A retrospective review of 56 consecutive adolescent males, ≤18 years from 2006 to 2016 with clinical varicocele who underwent laparoscopic surgical ligation or percutaneous embolization. Patient demographics, operative time, postoperative complications, success, varicocele grade, recurrence, and hospital charges were abstracted. Results: Mean age was 14.2 ± 2.1 years; 48 (86%) patients having undergone laparoscopic surgical ligation and 8 (14%) percutaneous embolization. Intervention in 45 (80%) patients was for testicular hypotrophy (mean 27.4% ± 15.6%) and 11 (20%) for pain symptomology. Median follow-up was 17.5 months (range 1-65 months). After ligation, 2 (4%) patients developed hydroceles (1 with subsequent hydrocelectomy) and 6 (12%) varicocele recurrence. There were no cases of hydrocele or varicocele recurrence after percutaneous embolization. Twenty ligation patients had postoperative scrotal ultrasound demonstrating an increase in testicular volume by a reduction in difference in testicular volume from 27.3% ± 14.7% preoperatively to 11.2% ± 13.6% postoperatively (P < .001). There was significant difference in mean operative time between the groups (surgical ligation 41.3 minutes versus percutaneous embolization 117.9 minutes, P < .001) and hospital charges for the procedure (surgical ligation $3983 versus percutaneous embolization $18.165, P < .001). Conclusions: Contrary to our hypothesis, percutaneous embolization has seemingly lower rates of postoperative hydrocele and varicocele recurrence in comparison to surgical ligation but with three times the exposure to general anesthesia and at four times the price.

Assessment of seminal calcium and magnesium levels in infertile men with varicocele before and after varicocelectomy.

BACKGROUND: Trace elements perform a vital role in all stages of human physiology, as well as reproduction. OBJECTIVE: This study aimed to assess seminal calcium (Ca) and magnesium (Mg) in infertile men associated with varicocele (Vx). MATERIALS AND METHODS: Overall, 50 men were divided into two groups: fertile men (n = 20) and infertile men who were scheduled for Vx surgical repair (n = 30). Exclusion criteria were as follows: azoospermia, smoking, leukocytospermia, and consumption of Ca and/or Mg supplements. All cases were subjected to history taking and clinical examination. Semen analysis and assessment of seminal Ca and Mg by the colorimetric method were carried out for all cases at the base point and 3 months postvaricocelectomy. RESULTS: Generally, the mean seminal Ca and Mg levels demonstrated significant decreases in infertile men with Vx compared with the healthy fertile men linked to higher Vx grade as well as Vx bilaterality. These seminal decreases demonstrated significant increases after Vx surgical repair. Collectively, seminal Ca and Mg levels showed a significant positive correlation (r = 0.665, p= 0.001). Besides, seminal Ca, Mg levels, and Ca/Mg ratio showed significant positive correlation with sperm concentration (r = 0.479, p = 0.001; r = 0.541, p = 0.001; r = 0.282, p = 0.001, respectively), sperm motility percentage (r = 0.493, p = 0.001; r = 0.477, p = 0.001; r = 0.353, P = 0.001, respectively), and sperm normal forms percentage (r = 0.578, p = 0.001; r = 0.520, p = 0.001; r = 0.430, p = 0.001, respectively). DISCUSSION AND CONCLUSION: Seminal Ca and Mg levels and Ca/Mg ratio are significantly decreased in infertile men associated with Vx compared with fertile men with significant increases after varicocelectomy.

Risk of herpes zoster infection in men with varicocele.

PURPOSE: Several diseases have been identified as stressful factors for herpes zoster (HZ) infection. In this study, we investigated the risk of HZ infection in men with varicocele. METHODS: We enlisted the data of patients with newly diagnosed varicocele between 2000 and 2012 from the Taiwanese National Health Insurance Research Database as case cohort. Four control patients were matched as per age and index year to a case patient. HZ diagnosis was the primary end point, and the follow-up period was considered as the time interval from the index date to the main outcome, withdrawal from the National Health Insurance program, or end of the study (31 December 2013). RESULTS: In total, 8720 patients were recruited (1744 with varicocele and 6976 controls); the overall mean age was 36 years. Majority (85%) of the participants were 20-49 years old. HZ incidence was higher in patients with varicocele (5.60 per 1,000 person-years) than in the control group (4.01 per 1,000 person years). Patients with varicocele were 1.37 times more likely to develop HZ than the controls after adjustment. Compared with the control cohort, the adjusted hazards ratio (HR) of the varicocele cohort was higher in patients younger than 49 years old (adjusted HR = 1.60). CONCLUSION: Men with varicocele had a higher risk of HZ development than those without varicocele, particularly those aged ≤49 years. Thus, stress from varicocele cannot be ignored in young men.

Extensive Assessment of Underlying Etiological Factors in Primary Infertile Men Reduces the Proportion of Men With Idiopathic Infertility.

Objective: Up to 40% of infertile men remain without a recognized cause (i.e., idiopathic infertility). We aimed to identify, categorize, and report the supposed causes of male infertility in a cohort of white-European men presenting for primary couple's infertility, by using a thorough and extensive baseline diagnostic work-up. Material and Methods: Cross-sectional study of 1,174 primary infertile men who underwent a thorough diagnostic work-up including: detailed medical history, physical examination, hormonal assessment, genetic testing, semen analyses; semen and urine cultures; testis color Duplex US. Men without any identified causal factor were considered as idiopathic. Six different etiological categories were established, and their prevalence was estimated. Logistic regression models estimated the risk of missing causal identification. Results: A possible causal factor was identified in 928 (81%) men. Hypogonadism was the most frequent identified cause (37%), followed by varicocele (27%). Genetic abnormalities were found in 5% of patients. A causal factor was more easily identifiable for the more severe infertility cases, and azoospermic men were those less likely to be defined as idiopathic (OR and 95% CIs: 0.09; 0.04-0.20). Relative proportion of identified causes remained constant during the 10-year study period (p>0.43). Conclusions: Due to a more comprehensive and extensive diagnostic work-up, at least one underlying cause of male infertility factor in 4 out of 5 infertile men can be identified. Men with a less severe phenotype remain a clinical challenge in terms of establishing a possible etiologic factor. Further studies are needed to assess which subset of infertile men deserves a more extensive work-up.

A Comprehensive Ultrasonographic Assessment of Pediatric and Adolescent Varicocele Can Improve Surgical Results.

PURPOSE: Undetected refluxing venous systems could cause persistence/recurrence of varicoceles in patients undergoing varicocelectomy. Color Doppler ultrasound (CDUS) is an important tool in the diagnosis and follow-up of varicocele, and could be successfully used to detect a venous reflux in the iliac-deferential district, usually involved in the recurrence/persistence of varicocele. MATERIALS AND METHODS: We compared 2 historical series of patients treated with Palomo laparoscopic varicocelectomy between 1994 and 2018. In group 1, preoperative scrotal CDUS was obtained, while in group 2, additional inguinal CDUS was performed in order to detect a refluxing deferential vein (DV). When a deferential reflux was found, the DV and internal spermatic vein were interrupted during the same Palomo laparoscopic varicocelectomy. RESULTS: A total of 449 patients underwent left laparoscopic varicocelectomy; 146 of them were not studied for deferential reflux with CDUS (group 1), while in the remaining 303, routine CDUS research of deferential reflux was obtained (group 2). The persistence/recurrence rate was significantly higher in group 1 (13.7 vs. 1%, p < 0.000). CONCLUSIONS: The research of a refluxing DV revealed a useful, cost-effective, and simple tool, allowing a better comprehension of the vascular anatomy of varicocele and, thus, a significant reduction of varicocele persistence/recurrence rate.

Paying the price for standing tall: Fluid mechanics of prostate pathology.

BACKGROUND: Age-dependent increase in the incidence of benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are both related to cell proliferation and survival controlled by intraprostatic free testosterone (FT) concentration. Paradoxically, BPH and PCa occur as circulating testosterone levels decrease, so any possible relationship between testosterone levels and development of BPH and PCa remains obscure. RESULTS: In BPH the enlarging prostate is exposed to high testosterone levels arriving directly from the testes at concentrations about hundredfold higher than systemic FT. This occurs because venous blood from the testes is diverted into the prostate due to the elevated hydrostatic pressure of blood in the internal spermatic veins (ISVs). Elevated pressure is caused by the destruction of one-way valves (clinically detected as varicocele), a unique phenomenon related to human erect posture. While standing, human males are ISVs vertically oriented, resulting in high intraluminal hydrostatic pressures-a phenomenon not found in quadrupeds. In this communication, we demonstrate the fluid mechanics' phenomena at the basis of varicocele leading to prostate pathology. CONCLUSIONS: So far, varicocele has been studied mostly for its etiologic role in male infertility and, thus, for its effects on the testes. It is becoming clear that varicocele is a major etiologic factor in BPH and likely also in PCa. Restoring normal testicular venous pressure by treatment of the abnormal ISV's in varicocele has been shown to avert the flow from the prostate with the effect of reducing prostate volume, alleviating symptoms of BPH, and increasing concentrations of circulating FT.

Assessment of seminal YKL-40 in infertile men with varicocele.

Several studies attempted to explain the negative impact of varicocele on spermatogenesis and fertilisation processes. YKL-40 is a novel glycoprotein biomarker that had been associated with several diseases. This quasi-interventional study aimed to assess the seminal levels of YKL-40 in infertile men with varicocele before and after varicocelectomy. Overall, 50 men were included in this study divided into 20 healthy fertile men and 30 infertile oligoasthenoteratozoospermic (OAT) men with varicocele that underwent varicocelectomy. All participants were subjected to history taking, clinical examination and scrotal Doppler. Also, semen analysis and seminal YKL-40 assessment were carried out in the start and 6 months after varicocele surgical repair. The results showed a significant increase in the mean seminal YKL-40 level in infertile OAT men with varicocele compared with the healthy fertile men. Six months post-varicocelectomy, the mean seminal KYL-40 level exhibited significant decreases correlated with improved sperm parameters. Overall, seminal levels of YKL-40 showed significant negative correlations with sperm concentration, total sperm motility and sperm normal morphology. It could be concluded that seminal YKL-40 is elevated in infertile OAT men with varicocele where varicocelectomy induces decreased seminal YKL-40 levels correlated with improved semen parameters.

Varicocele Embolization: An Assessment of the Quality and Readability of Online Patient Information.

AIMS AND OBJECTIVES: Varicocele embolization is a growing treatment modality owing to the safety, efficacy, and quick return to work following the procedure. The internet is the most dominant source of information for many. We aimed to assess the quality of information accessible by patients considering treatment. MATERIALS AND METHODS: A list of applicable, commonly used searchable terms was generated. Each term was assessed across the five most-used English language search engines to determine the two most commonly used terms. These two terms were then investigated across each search engine, with the first 25 web pages returned by each engine included for analysis. Duplicate web pages, nontext content such as video or audio, and web pages behind paywalls were excluded. Web pages were analyzed for quality and readability using validated tools including DISCERN score, JAMA Benchmark Criteria, HONcode Certification, Flesch Reading Ease Score, Flesch-Kincaid Grade Level, and Gunning-Fog Index. Secondary features including age, rank, author, and publisher were recorded. RESULTS: The most common applicable terms were "Testicular embolization" (378,300 results) and "Varicocele embolization" (375,800 results). Mean DISCERN quality of information provided by websites is "fair"; Adherence to JAMA Benchmark Criteria was 13.5%. Flesh-Kincaid readability tests demonstrated an average "9th grade" reading level. Scientific journals showed the highest quality scores, but were least up to date with an average web page age of 11.2 years. Web pages produced by "for-profit" organizations were the second most current (average age 2.7 years), but displayed the lowest quality of information scores. CONCLUSION: While quality of online information available to patients is "fair," adherence to JAMA benchmark criteria is poor. "For-profit" organization websites are far more numerous and significantly more up-to-date, yet showed significantly lower quality of information scores. Scientific journals were unsurprisingly of higher quality, yet more challenging for the general public to read. These findings call for the production of high-quality and comprehensible content regarding interventional radiology, where physicians can reliably direct their patients for information.

Venous leg symptoms in patients with varicocele: A multicenter assessment study (VEIN-TURKEY study).

OBJECTIVE: The aim of this study is to evaluate chronic venous disease symptoms by using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) questionnaire in varicocele patients. MATERIAL AND METHODS: The study was designed as a prospective, case controlled study and conducted in four hospitals from Turkey. A total of 600 patients who admitted to urology outpatient clinic were enrolled to the study. After the exclusion of 44 patients who do not match the inclusion criteria, the remaining 556 patients were examined for the presence and grade of varicocele and subsequently examined clinically for the presence of chronic venous disease findings. Finally, patients were asked to answer the VEINES-Sym questionnaire consisting of 10 items. All patients' demographic parameters, cardiovascular risk factors, other co-morbid diseases and drug usage were noted. RESULTS: Patients were classified into two groups: varicocele (+) group ( n = 269) and varicocele (-) group ( n = 287). VEINES-Sym scores of varicocele patients were lower compared to patients without varicocele (41.41 ± 5.21, 43.19 ± 3.22, respectively, p < 0.001). Grades of varicocele significantly but inversely correlated with VEINES-Sym score ( r = 0, -206, p = 0.001). Logistic regression analysis revealed that presence of varicocele irrespective of grading significantly and independently associated with the presence of aching (odds ratio: 2.054, 95% confidence interval: 1.265-3.338, p = 0.004) and throbbing (odds ratio: 2.586, 95% confidence interval: 1.353-4.943, p = 0.004). CONCLUSION: Varicocele patients have lower VEINES-Sym scores compared to patients without varicocele and this finding is inversely correlated with the degree of the varicocele. This association supports the hypothesis that there may be a systemic vessel wall abnormality in venous disease patients. Patients with symptoms related to vascular dilatation in any territory may deserve to be assessed systematically with the support of further clinical studies.

The use of diffusion-weighted MR imaging in the functional assessment of the testes of patients with clinical varicocele.

We aimed to evaluate the use of diffusion-weighted imaging (DWI) in the assessment of the varicocele effect on testicular parenchyma and spermatogenesis, with estimation of apparent diffusion coefficient (ADC) value changes in the testicular parenchyma. We prospectively evaluated 30 consecutive patients (18 patients with bilateral varicocele and 12 patients with unilateral varicocele) and 10 healthy controls. US and DWI were performed to all patients. A total of 80 testes were included, which divided into three groups: group A: testes ipsilateral to the varicocele (n = 48, 60%); group B: testes contralateral to the varicocele (n = 12, 15%); and group C: normal testes of the control (n = 20, 25%). There was a statistically significant difference in mean ADC value between all groups (p-value < 0.001). In groups A and B, there was a negative correlation between mean ADC values and varicocele grade as well as pampiniformis venous diameter. In group A, there was a significant positive correlation between mean ADC value and sperm count (p-value = 0.01, r-value = 0.48) as well as sperm motility (p-value = 0.04, r-value = 0.33). DWI sequence can be used to evaluate the sequel of varicocele, with decreased ADC values that are significantly correlated with abnormal semen parameters. Thus, ADC values may be considered as an ancillary indicator of testicular parenchyma changes.

An Infertile Couple's Long and Expensive Path to Varicocele Repair.

OBJECTIVE: To characterize the pathways to care that infertile couples requiring varicocele repair (VR) pursue prior to presenting to a male fertility clinic. METHODS: An IRB-approved single center retrospective review of patients undergoing VR after presentation to an academic male fertility clinic was performed. Patients whose charts included partner histories were assessed for duration of attempting conception, prior workup, and assisted reproductive technology (ART) use. RESULTS: A total of 405 couples were included. At presentation, mean age was 34.4 (SD ± 6.5) years for men and 31.1 (SD ± 4.3) years for women (P < .0001). A couple's first visit to a physician was a gynecologist in 59% (198/334) of couples, a reproductive endocrinologist (REI) in 25% (83/334) of cases, with 14% (47/334) presenting without a previous female workup and were self-referred, and 2% (6/334) seeing both a gynecologist and REI prior to presentation. On average, couples attempted pregnancy for 22.3 (SD ± 21.1, range 0-120) months prior to presentation. Eighteen percent of couples underwent ART prior to presentation. Couples who had undergone ART had lower pre-VR total motile sperm counts compared to couples not pursuing ART prior to presentation (P = 0.031). The majority (70.4%) of females had no abnormality in their workup, making varicocele the only correctable factor for infertility in the couple. CONCLUSIONS: Our findings show a significant delay in referral of infertile men requiring VR. Eighteen percent of couples underwent costly ART prior to an inexpensive male workup. In an era of medical cost containment, early referral to a male infertility specialist is imperative.
