Microscopic Testicular Sperm Extraction in Patients with Klinefelter Syndrome: Long-Term Outcomes from a Single Center

Objective: Klinefelter syndrome (KS) represents a sex chromosome anomaly observed in approximately 1 in 500–600 phenotypic males. It is observed in 3% of infertile males and up to 11.9% of azoospermic males. KS manifests in either non-mosaic (47, XXY) or mosaic (47, XXY/46, XY) forms, with 85% of cases presenting as the non-mosaic 47, XXY karyotype. The average rate of surgical sperm retrieval in patients with KS is around 50%, ranging from 28% to 69%. In this study, we aimed to present the outcomes of microscopic testicular sperm extraction (micro-TESE) in patients with non-mosaic KS. Materials and Methods: The results of 61 patients diagnosed with KS, who presented to the Harran University Urology Clinic with azoospermia between 2017 and 2024, were retrospectively reviewed. Hormonal assessments, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and total testosterone (TT), were conducted for all patients, and their partners underwent gynecological evaluations for infertility. Testicular dimensions were recorded via scrotal ultrasonography. Patients were categorized into TESE-positive and TESE-negative groups, and parameters were compared between these groups. Results: The mean age of the patients was 29.0±5.1 years, and their mean infertility duration was 5.9±4.1 years. The sperm retrieval rate was 29.5% (n=18). Mean levels of FSH, LH, prolactin, estradiol, and TT were 44.9 IU/L, 23.3 IU/L, 10 nmol/L, 31.4 pmol/dL, and 219 ng/dL, respectively. Sperm was retrieved in 18 patients (29.5%), while no sperm was obtained in 43 (70.5%). No significant correlation was observed between patient age, testicular size, serum levels of FSH, LH, prolactin, estradiol, and TT, and sperm retrieval rates when comparing the TESE-positive and TESE-negative groups (P>0.005). Conclusion: In patients with non-mosaic KS, hormonal parameters, age, and infertility duration were not found to be significant predictors of the success of micro-TESE in sperm retrieval.

Epithelioid (Histiocytoid) hemangioma of the testis: A case report and literature review of a rare benign tumor.

Testicular hemangioma is a rare benign vascular neoplasm originating from the inner layer of the tunica albuginea, predominantly affecting the pediatric population and often associated with hemangiomas in other organs. Histopathologically can be categorized into four types, including capillary, cavernous, papillary endothelial hyperplasia, and epithelioid (histiocytoid). We report a case of a 24-year-old presenting with left inguinal pain, diagnosed with an epithelioid (histiocytoid) hemangioma of the testis. Diagnostic evaluation included scrotal doppler ultrasonography, which revealed a small, hypoechoic formation with evident vascularization. Serum tumor markers were within normal limits. Surgical excision via testis-sparing surgery (TSS) was performed based on frozen section analysis. A literature review underscores the rarity of testicular histiocytoid hemangiomas. Advancements in diagnostic technique have improved the accuracy of diagnosis and allowed for more conservative surgical approaches, preserving fertility and minimizing long-term adverse effects. In conclusion, while testicular hemangiomas may present characteristic features on ultrasound, frozen section examination remains crucial in guiding surgical decision-making. TSS offers significant advantages over traditional excisional surgery, including reduced morbidity and preservation of cancer control, making it an essential option in the management of testicular hemangiomas, particularly in young patients concerned about fertility preservation.

Primary scrotal lipoma in a child: a rare case report and review of literature

Lipoma is a common benign tumor of the body surface, while scrotal lipoma is relatively rare. We report a case of scrotal lipoma in a 5-year-old boy, which presented as a progressively enlarging scrotal mass. Scrotal ultrasonography highly suggested a lipoma, and a scrotal mass resection was performed, leading to a final pathological diagnosis of benign scrotal lipoma.

7709 Ovotesticular Difference of Sex Development: Prognostic Evaluation, Sex Assignment, and Ethics

Abstract Disclosure: X. Xu: None. Y. Lin: None. B. Shivanna: None. A. Lee: None. J.C. Hakim: None. D.G. Mann: None. L.M. Noll: None. P. Georgiadis: None. S.K. Gunn: None. L.P. Karaviti: None. Background: Our case provides the identification and management of a newborn baby with ovotesticular syndrome, which was formerly known as true hermaphroditism. The term was classically derived from Greek mythology in which the deity 'Hermaphroditus', merging with the nymph Salamis, embodied both male and female attributes. The term 'true hermaphroditism' is now avoided due to its stigmatizing connotations. Ovotesticular difference of sex development (DSD) is an exceedingly rare condition, occurring in fewer than 1 in 20,000 births. This condition involves the coexistence of functional ovarian and testicular tissue within one individual, presenting a challenge in sex assignment due to unpredictable gender development. Clinical Case: This is a single case of the presence of ovarian and testicular differentiation on one side and a transitional zone of mixed pattern. Prenatal genetic testing consistent 46,XX karyotype. Initial ultrasound at the outside hospital revealed a uterus and right testicle. The baby exhibited Prader stage 4 genitalia, with a palpable gonad in the right labioscrotal area and the left gonad not palpable. Prophylactic hydrocortisone was started due to concerns regarding NR5A1/SF1 mutation. Further evaluations, including genetic tests, hormonal assessments, urinalysis and kidney ultrasound for the WT1 mutation, and scrotal and pelvic ultrasounds, were conducted. The high-dose ACTH stimulation test ruled out adrenal insufficiency. The testosterone level was in the male range, and the HCG stimulation test further confirmed functioning Leydig cells. The postnatal karyotype was 46,XX, and chromosome microarray analysis showed no abnormalities. Our approach to this case was multidisciplinary, including our endocrine experts, urologist, gynecologist, ethicist, and psychologist. We discussed the fluidity of sex assignment and addressed the degree of virilization, nature of the gonadal tissue, and emphasized the necessity of regular clinical follow-up. Our main concern was to educate the parents and protect the choices of the child. In this case, the child assumed a male sex assignment, as a result of the decision-making process between our team and the parents. In this context we did emphasize the fluidity of sex assignment. Clinical Lesson: Long-term outcomes for ovotesticular DSD remain understudied. Existing reports highlight varying rates of gender dysphoria, sexual function, and psychological well-being. Our approach to managing ovotesticular DSD involved a framework emphasizing ethical considerations and parental involvement. We advocated for and practiced a shared decision-making model involving healthcare providers, parents, and ultimately the patient. Presentation: 6/3/2024

Ultrasonographic Assessment of Testicular Biometry and Arterial Blood Flow in Pre- and Postpubertal Miranda Donkeys: Correlations With Semen Quality Parameters.

The main goals of this study were to document and compare the normal ranges of testicular haemodynamic parameters in pre- (aged 8-12 months; n = 4) and postpubertal (aged 24-259 months; n = 16) Miranda donkeys in the breeding season, and to correlate animal biometric data and testicular Doppler indices with basic semen quality parameters of sexually mature jacks. Colour and pulsed-Doppler ultrasonography were employed to assess blood flow in the left and right distal supratesticular artery (DsTA) and their marginal branches (marginal arteries-MA). Peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI) and resistive index (RI) were evaluated in both blood vessels, and TAMV (time-averaged mean velocity), TABF (total arterial blood flow) and TABF rate (TABF-R) were calculated for MA. The mean diameter of MA was greater (p < 0.05; 0.24 ± 0.05 vs. 0.19 ± 0.05 cm; mean ± SD) but TABF-R was less (p < 0.05; 0.004 ± 0.004 vs. 0.02 ± 0.01 mL/s/cm3) in sexually mature donkeys compared with prepubertal animals. Apart from RI values for the right testicle of prepubertal donkeys, PI and RI were consistently greater (p < 0.05) in DsTA compared with MA. Significant correlations were found among select biometric and haemodynamic attributes of the testes (height, width and length, TV, TTV and PSV-ST) and ejaculate characteristics (volume, sperm defects-total, head and midpiece) in sexually mature donkeys (n = 8). The present results highlight the importance of scrotal ultrasonography for the reproductive assessment of jacks and provide reference values, based on the available subpopulation of Miranda donkeys that can be used in their clinical and reproductive management and research, or conservation programmes.

Testicular Pain Following Laparoscopic Donor Nephrectomy: An Underreported Complication.

Introduction: Testicular pain (TP) after laparoscopic donor nephrectomy (LDN) is a relatively underreported complication. This study aimed to investigate the incidence, characteristics, and factors associated with ipsilateral TP after left-sided LDN. Materials and Methods: This study prospectively collected baseline data and surgical details for all patients who underwent left-sided LDN during the study period. Each patient underwent scrotal ultrasonography 1 month postoperation. Donors were categorized by the level of gonadal vein ligation (level 1 at the renal vein confluence and level 2 at or below the iliac vessel crossing) and the presence or absence of TP. The characteristics of pain and demographics were compared across the groups. Results: Among 61 male patients who underwent left-sided LDN between March 2017 and December 2018, 54.1% (33/61) experienced ipsilateral TP. TP was more frequent in level 2 donors (64.3%) than in level 1 (45.5%), but the difference was not statistically significant (p = 0.141). Most TP occurred within a week (60.6%), was mild (75.8%), and resolved within 3 months (63.7%). The incidence of varicocele and hydrocele was 32.8% and 34.4%, respectively. The occurrence of TP was not significantly associated with the presence of varicocele or hydrocele and other factors. Conclusion: More than half of the male donors who underwent LDN experienced TP. The findings emphasize the importance of discussing this potential complication during preoperative counseling. This study found no significant association between TP and the level of gonadal vein ligation or the presence of varicocele, warranting further investigation into the cause of TP.

Epididymal Cyst Lesions Are Not Associated With Impaired Semen Parameters Among Men Presenting for Fertility Evaluation.

Epididymal cyst lesions (ECLs) include both spermatoceles and epididymal cysts and are often incidentally found on physical exam or scrotal US (SUS). We aimed to determine the association of ECLs and semen parameters among men presenting for fertility evaluation. We reviewed men at our institution who had at least 1 semen analysis and SUS available for review between 2002 and 2022. SUS data included testicular measurements, presence or absence of subclinical varicocele, and size and laterality of ECL, if present. Demographic and clinical information including serum testosterone and follicle-stimulating hormone and semen parameters were compared between men with and without ECLs. Among 861 men, 164 (19%) had unilateral right ECL (median 4 mm, interquartile range 3-8 mm), 189 (22%) had unilateral left ECL (median 4 mm, interquartile range 3-9 mm), and 113 (13%) had bilateral ECL. Patients with ECLs were significantly older than men without ECLs at the time of evaluation but had no statistically significant difference in semen volume, sperm concentration, sperm motility, sperm morphology, total motile sperm count, or serum hormonal values. Analysis of men with unilateral and bilateral ECLs showed that ECL size and laterality did not significantly correlate with any semen parameter evaluated. We found no association between ECLs and semen parameters. Patients should be counseled toward conservative management with observation for asymptomatic ECLs in the setting of fertility evaluation.

The role of the radiologist in the evaluation of male infertility: recommendations of the European Society of Urogenital Radiology-Scrotal and Penile Imaging Working Group (ESUR-SPIWG) for scrotal imaging.

The Scrotal and Penile Imaging Working Group (SPIWG) of the European Society of Urogenital Radiology (ESUR) aimed to produce recommendations on the role of the radiologist in the evaluation of male infertility focused on scrotal imaging. The authors independently performed an extensive literature Medline search and a review of the clinical practice and consensus opinion of experts in the field. Scrotal ultrasound (US) is useful in investigating male infertility. US abnormalities related to abnormal sperm parameters (sperm concentration, total count, motility, and morphology) are low testicular volume (TV), testicular inhomogeneity (TI), cryptorchidism, testicular microlithiasis (TML), high-grade varicocele, bilateral absence of vas deferens, bilateral dilation and echotexture abnormalities of the epididymis. The proposed ESUR-SPIWG recommendations for imaging in the evaluation of male infertility are therefore: to measure TV; investigate TI; perform annual (US) follow-ups up to age 55 in men with a history of cryptorchidism/orchidopexy and/or in men with TML plus "additional risk factors" or with "starry sky" TML; perform scrotal/inguinal US in men with nonpalpable testis; perform scrotal US in men with abnormal sperm parameters to investigate lesions suggestive of tumors; evaluate varicocele in a standardized way; evaluate the presence or absence of vas deferens; investigate the epididymis to detect indirect signs suggesting obstruction and/or inflammation. The ESUR-SPIWG recommends investigating infertile men with scrotal US focusing on TV, inhomogeneity, localization, varicocele, vas deferens, and epididymal abnormalities. Cryptorchidism, TML, and lesions should be detected in relation to the risk of testicular tumors. The ESUR-SPIWG recommendations on scrotal imaging in the assessment of male infertility are useful to standardize the US examination, focus on US abnormalities most associated with abnormal semen parameters in an evidence-based manner, and provide a standardized report to patients. So far, ESUR-SPIWG recommendations on scrotal imaging in the assessment of male infertility were not available. The ESUR-SPIWG recommends investigating infertile men with scrotal US focusing on testicular volume, inhomogeneity, localization, varicocele, vas deferens and epididymal abnormalities, and assessing cryptorchidism, testicular microlithiasis and lesions in relation to the risk of testicular tumors. The ESUR-SPIWG recommendations on scrotal imaging in the assessment of male infertility are useful to standardize the US examination, focus on US abnormalities most associated with abnormal sperm parameters in an evidence-based manner, and provide a standardized report to patients.

Epididymal cysts in children: frequency, clinical characteristics, and management strategies.

Epididymal cysts (ECs) are uncommon in the pediatric population. The objective of this study was to evaluate the frequency, clinical characteristics, and management strategies of ECs in children. We performed a retrospective review of pediatric scrotal ultrasounds between January 2014 and August 2022 to identify children with ECs. One hundred and forty-three children boys were found to have ECs, with 95 being pre-pubertal and 48 post-pubertal. The age of the patients ranged from 1 day to 18 years, with a mean age of 10.64 ± 4.55 years. The size of the cysts varied from 2 mm to 35 mm. The most common comorbidities observed were hydrocele, testicular microlithiasis and varicocele. The majority of ECs were detected through routine physical examination. Conservative management was employed for all patients, except for one who required surgical excision. Resolution of ECs occurred in 12 patients, while a reduction in cyst size was observed in 6 cases. Conversely, 2 patients experienced an increase in cyst size, and 6 patients exhibited an increase in cyst number during the follow-up period. Conservative management is the preferred approach for the majority of cases, with surgical intervention reserved for specific instances.

Advanced Sonographic Techniques in the Comprehensive Evaluation and Diagnosis of Male Infertility.

Background Infertility affects many couples, with male factors being responsible for over half of the cases. Male infertility can arise from various testicular illnesses, such as varicocele and cryptorchidism, as well as posttesticular disorders, like ejaculation abnormalities. Infertility is defined as the inability to conceive after 12 months of unprotected sexual activity or after six months for women over 35. Diagnostic techniques such as semen analysis and scrotal ultrasonography are done to evaluate conditions like varicocele and epididymo-orchitis. This study aims to assess the diagnostic utility of ultrasonography for male infertility and compare its findings with those from surgery and clinical care. Methodology All patients were referred to the Department of Radiology,Tertiary Care Hospital, South India, for transrectal and scrotal ultrasonography, using a high-frequency transducer with a frequency of 7.5 MHz and a color Doppler when necessary. The study included all male patients with infertility and abnormal semen analysis, as well as those with infertility accompanied by scrotal abnormalities detected during clinical examination. Patients were placed in the left lateral decubitus position for the transrectal ultrasonography examination. The testes and epididymis were thoroughly examined on both sides and compared regarding symmetry, size, texture, and vascularity. Results Varicocele was the most frequent anomaly detected by both clinical examination and ultrasonography. Ultrasound detected 30 cases of varicocele, whereas clinical examination diagnosed 15 cases. Hydrocele was identified in eight cases through clinical examination and in 15 cases through ultrasound. Epididymal cysts were found in five cases via clinical examination, while both clinical examination and ultrasonography discovered epididymitis in 10 cases. Overall, the number of anomalies detected by ultrasound was significantly higher than those found by physical examination, with a statistically significant p value of 0.001. Conclusion Transrectal ultrasound provides high-resolution imaging of the prostate, seminal vesicles, and distal vas deferens, which aids in diagnosing obstructive azoospermia. Imaging is a valuable supplement to clinical examination and laboratory studies for accurately identifying anatomy and abnormalities. Both transrectal and scrotal ultrasonography offer crucial information in diagnosing male infertility. Ultrasonography is more effective in identifying pathological abnormalities than clinical palpation.

The Clinical Management of Intrascrotal Extratesticular Masses With Evaluation of Histopathologic Findings

ObjectiveTo contribute to the literature by sharing the clinical presentation, surgical approach, postoperative complications management and follow-up protocols of the patients we operated on due to intrascrotal extratesticular mass. MethodsThirty-two patients admitted due to intrascrotal extratesticular mass were included in the study. Demographic and clinical characteristics of the patients such as age, initial clinical presentation, physical examination, radiological imaging findings such as scrotal Doppler ultrasonography and magnetic resonance imaging, mass size and characteristics, surgical treatment procedures, operation notes, and patient follow-up visits were retrospectively examined and evaluated from the patient files. ResultsThe median age of the 21 32 individuals included in the study was 52(interquartile range (IQR):[45.0-60.5]) years. The primary reason for initial presentation was a palpable mass in 25 (78.1%) patients, pain in 13 (40.6%) patients, and scrotal swelling in 8(25%) patients. The median mass diameter was 4.4 (IQR:[3.1-5.7]) cm. Surgical treatment involved inguinal excision in 29 cases (90.6%) and inguinoscrotal excision in 3 cases(9.4%). All patients were treated with testicle sparing surgery. The most common tumor location, observed in 27 cases (84.3%), was the epididymis. The most frequent histopathological diagnosis was epididymal cyst, identified in 13 patients(40.6%). Pathology results showed that the mass was removed with negative margins in all patients. ConclusionTesticular-sparing surgery through the inguinal approach is one of the surgical methods that can be preferred for intrascrotal extratesticular masses. This approach can both preserve the testicle and achieve successful surgical results. Studies with larger samples are needed on this subject. Trial registrationThis study was approved by the Erzurum Medicine Faculty University Local Ethics Committee (approval number: BAEK 2023/08-105).

Encysted spermatic cord hydrocele: A case series

Introduction and importanceEncysted spermatic cord hydrocele is a rare anomaly characterized by obstruction of processus vaginalis closure. Clinically, it presents as a swelling in the inguinal region extending to the upper scrotum and does not communicate with the peritoneal cavity. It is often mistaken for indirect inguinal hernias, inguinal lymphadenopathy, undescended testis, and primary tumors of the cord in infants and children, making the diagnosis challenging. Case presentationWe report the cases of five male patients aged nine months to 12 years who presented with painless swelling on the right side of the scrotal region. Physical examination revealed firm masses in the right inguinal region with positive transillumination, negative cough impulse tests, and irreducibility. Inguinal and scrotal ultrasonography showed an anechoic cystic lesion with thin walls, without any signs suggestive of a hernia. Patients were diagnosed with encysted spermatic cord hydrocele and advised to undergo cyst excision. The postoperative periods were uneventful, and expected recovery was observed at one-week and one-month follow-ups. Clinical discussionEncysted spermatic cord hydroceles are rare causes of painless inguinal swelling. The medical history and clinical findings can be used to establish a diagnosis, which can be confirmed using ultrasonography. Management depends on differentiating between spermatic cord hydrocele and scrotal hydrocele and involves considering the type. Treatment options range from conservative measures to surgery, particularly for non-communicating hydroceles that persist beyond 12–18 months or enlarge in size. ConclusionEncysted hydrocele of the cord is rare and is often mistaken for indirect inguinal hernias in infants and children. This similarity makes the diagnosis challenging and necessitates vigilance from clinicians. Surgical intervention results in optimal outcomes, especially in cases where the hydrocele persists beyond 12–18 months or with size progression.

The impact of ultrasound on testicular loss in cases of testicular torsion in children

PurposeUltrasound as a diagnostic tool in suspicion of testicular torsion is still highly debated. In this investigation, we aimed to evaluate whether time spent on scrotal ultrasonography had a negative impact on testicular loss.MethodsPatients’ records containing a scrotal ultrasound and/or surgical procedure codes for testicular interventions on suspicion of testicular torsion were examined. Patients aged 0–15 years admitted during 2015–2019 at Copenhagen University Hospital, Rigshospitalet were included.ResultsIn total, 1566 patients underwent an ultrasound and 142 of these proceeded to surgery while 13 patients proceeded directly to surgery without an ultrasound. The rate of testicular loss with a preceding ultrasound was 23% versus 42% without (p = 0.18). Four cases of testicular torsion were misdiagnosed by ultrasound resulting in a sensitivity of 95.4% and specificity of 95.6%. The mean diagnostic delay from ultrasound examination was 55 ± 39 min, and the mean time from ultrasound to surgery was at 169 ± 76 min versus 171 ± 72 min without ultrasound.ConclusionIn a clinical setting, ultrasound provided a reliable tool for the diagnosis of testicular torsion and did not seem to increase the orchiectomy rate.

Unmasking the unexpected: Testicular tumour uncovered as a result of scrotal trauma

AbstractWe present a case of a 17‐year‐old male with a testicular tumour diagnosed after trauma. A 17‐year‐old male patient came to our clinic with swelling in the right hemiscrotum. The patient had a history of right scrotal blunt trauma 3 weeks before the admission and had no history of urological surgery or chronic disease. The patient doesn't use tobacco, alcohol, or illicit drugs. Genitourinary system examination revealed swelling and tenderness on palpation in the right hemiscrotum. The right testicle was not palpable. The left hemiscrotum was normal. The left testicle had a normal size and shape. Testicular tumour markers were high (AFP:196 μg/L (N: 0–8 μg/L), b‐HCG: 916 mIU/mL (N: &lt;10 mIU/mL), LDH: 364 U/L (N: 0–265 U/L). Scrotal ultrasonography and magnetic resonance imaging revealed that there were areas of 9 × 9 × 11 cm in size of the right scrotal region without viable testis tissue, hematoma area, and areas compatible with necrosis. These findings were related to intratesticular rupture due to trauma. Abdominal tomography revealed lymphadenopathies of approximately 6 × 3 cm in the anterior paracaval area and approximately 4 × 3 cm in the anterior aspect of the psoas muscle. We performed right radical inguinal orchiectomy on the patient. Testicular tumour markers were still high on the 8th postoperative day (AFP:120 μg/L (N: 0–8 μg/L), bHCG: 680 mIU/mL (N: &lt;10 mIU/mL), LDH: 200 U/L (N: 0–265 U/L)). The testicular tumour was diagnosed as mixed germ cell tumour (50% Yolk Sac, 30% Embryonal Carcinoma, 20% Teratoma). The tumour diameter was 9 cm, surgical margins were intact, there was rete testis invasion, and no tumour was detected in the tunica vaginalis. No tumour invasion was seen in the soft tissue around the spermatic cord (pT2). The patient received 3 cycles of chemotherapy with bleomycin, etoposide, and cisplatin. We suggest that patients presenting with scrotal trauma should be carefully evaluated for testicular malignancy, and if malignancy is suspected, radical inguinal orchiectomy should be preferred for the operation.

Preoperative and Intraoperative Scrotal Duplex Ultrasound in the Assessment of Varicocele: A Comparative Study

Background: This study aimed to compare the accuracy of preoperative and intraoperative scrotal duplex ultrasound (SDU) in assessing varicocele, a common cause of male subfertility.Methods and Results: The study was conducted on 20 male patients scheduled for subinguinal varicocelectomy at a tertiary care hospital from March 2022 to March 2023. We used Grey-Scale US and Doppler US to evaluate testicular size, vein diameter, arterial flow parameters, and retrograde flow. We found that the preoperative scrotal duplex was a good and accurate method for assessing the grading of varicocele, and there was no significant difference in vein diameter or venous reflux between preoperative and intraoperative assessments. However, we observed a significant increase in the number of veins and testicular volume during intraoperative SDU compared to preoperative scrotal SDU.Conclusion: SDU is a reliable tool for determining testicular volume and provides objective, accurate, and reproducible measurements of testicular volume.

(206) Novel Observations about Epididymal Cysts Found in a Cohort of Michigan Men

Abstract Introduction Epididymal cysts (EC) are an incidental finding on scrotal ultrasounds (SUS), with an anecdotal prevalence from 5-20% with peaks at age 2 and in puberty. A recent survey at a children’s hospital in Michigan found that up to 35% of boys 15 or older had ECs. While adult men often demonstrate EC, comparatively few papers characterize the prevalence of ECs in adults. It is presumed that ECs most commonly develop during their 20s-40s but no clear prevalence by age has been established in the general adult population. Objective This present research will investigate within the same geographic region the prevalence of ECs in adult men. Methods A retrospective review was conducted for men 18-years-of-age and older who underwent a Michigan hospital-based SUS between 2010 – 2015. Patients without EC and EC patients were compared using two-sample t test, associations between age and presence of ECs were evaluated by chi-square test, and associations between age and TTV were evaluated by one-way ANOVA and Pearson’s correlation coefficient. Results 357 out of 801 men (44.6%) were found to have sonographic evidence of ECs. When separated into age groups, the prevalence of ECs significantly increased (p=0.041) with increasing age. In men with only ECs, their TTV did not significantly decrease with age (r = 0.06, p=0.684), unlike men without EC (r = 0.18, p=0.028). Conclusions This geographic cohort of men have the highest prevalence of ECs reported in the global literature. Two novel observations are that ECs frequency increases with age and TTV is preserved with age in men with ECs. TTV correlates significantly with FSH, LH, testosterone, and sperm health – further investigation should examine how preserved TTV may correlate with these values. Future studies should also examine the link between endocrine disrupting compound exposure and development of ECs. Disclosure No.

The management of testicular torsion: A survey of Turkish pediatric surgeons and pediatric urologists.

This study aimed to evaluate the approaches of pediatric surgeons and pediatric urologists in Türkiye regarding the diagnosis and treatment of testicular torsion (TT) and their adherence to the European Association of Urology (EAU) pediatric urology guideline. A survey consisting of 19 questions, accompanied by an annotation describing the objective of the study, was emailed to pediatric surgeons and pediatric urologists in June and July 2023. Of the 95 respondents, 62.1% had over 10 years of experience, and 48.4% treated more than five cases of TT annually. Of the participants, 87.4% stated that scrotal Doppler ultrasonography (US) was always used, and 12.6% stated that US was used in cases of doubtful diagnosis. Concerning treatment, 14.7% reported performing manual detorsion, 70.5% never did, and 14.7% did so only if the operating room was unavailable soon. A total of 92.6% of participants opted for emergency surgery. Among participants who perform manual detorsion, 71.4% perform surgery within 24 hours after successful manual detorsion. Regarding fixation of the contralateral testicle, 14.7% never performed it, and 27.4% did so only when they performed an orchiectomy on the torsion testicle. While most participants follow EAU pediatric urology guidelines by performing emergency surgery, the rate of manual detorsion is low. Few participants stated that emergency surgery may not be performed after manual detorsion. While all of the participants performed fixation of the torsion testicle in accordance with the guidelines, the same adherence was not observed in the contralateral testicle.

Evaluation of scrotal pathology: an observational study

Background: Scrotal issues often prompt patients to seek evaluation through physical examinations and scrotal ultrasonography. Accurate diagnosis requires a comprehensive exploration of potential conditions, with both grayscale ultrasonography (USG) and duplex Color Doppler ultrasonography employed for assessment. Methods: This prospective observational study, conducted at Dhaka Medical College Hospital in Bangladesh from July 2004 to June 2005, aimed to compare the effectiveness of grayscale ultrasonography and duplex color Doppler ultrasonography in evaluating scrotal pathology. Fifty-two patients with intra-scrotal disease were included using purposive sampling. Grayscale USG and duplex color Doppler ultrasonography were performed, and demographic and clinical data were processed using MS Excel and SPSS version 23.0. Results: Grayscale ultrasonography identified hydrocele, varicocele, and epididymitis in 21%, 15%, and 13.5% of cases, respectively. Color Doppler imaging revealed various pathologies, with varicocele and hydrocele most common (21.20%). Diagnostic accuracy varied between the two techniques, with Color Doppler excelling in specific conditions such as testicular torsion (100% accuracy, sensitivity, and specificity). Overall, Color Doppler demonstrated superior accuracy (96.10%) compared to grayscale (80%). Conclusions: While both grayscale ultrasonography and duplex Color Doppler ultrasonography are valuable tools for evaluating scrotal pathology, the latter demonstrates superiority in terms of accuracy, sensitivity, and specificity. Color Doppler's effectiveness in diagnosing specific conditions suggests its preference for comprehensive scrotal assessments.

Indocyanine green (ICG)-GUIDED lymphatic sparing laparoscopic varicocelectomy in children and adolescents. Is intratesticular injection of the dye safe? A mid-term follow-up study

Laparoscopic Palomo varicocelectomy using indocyanine green (ICG) fluorescent lymphography (FL) is standardized technique to perform lymphatic sparing and avoid post-operative hydrocele. No data regarding the safety of intratesticular injection of ICG are currently available. The study aimed to assess the safety and efficacy of this procedure at mid-term follow-up. Seventy-two patients (median age 14.5 years) undergoing laparoscopic Palomo varicocelectomy using ICG-FL from January 2019 to July 2022, were enrolled. Operative indication was high-grade varicocele in all patients, associated symptoms in 30/72 (41.7%) and left testicular hypotrophy in 42/72 (58.3%). Follow-up included clinical examination at 1, 6, 12 months and scrotal Doppler ultrasonography (US) at 12 months postoperatively to assess varicocele persistence, hydrocele, and injections-related complications. Lymphatic sparing was achieved using ICG-FL in all cases. No intra-operative complications or adverse reactions secondary to ICG occurred. The median follow-up was 22.8 months (range 11-49). Self-limited scrotal hematoma at the injection site occurred in 1/72 (1.4%). Intratesticular hypoechoic millimetric area was detected at the injection site in3/72 (4.2%) on US. This finding disappeared after 1-year observation in 2/3 cases (66.7%) (Figure). Persistent grade II varicocele was observed in 4/72 (5.5%), not requiring re-intervention. No hydrocele occurred and 14/22 (63.6%) with pre-operative hypotrophy showed catch-up growth. ICG-FL was clinically safe, with no allergy or systemic adverse reactions to the dye reported in this series. No injury directly related to the injection of the dye was clinically observed, except for self-limiting scrotal hematoma in one patient. A millimetric hypoechoic and avascular area in the body of the left testicle at the injection site was found on scrotal US at 1-year follow-up in 3 patients of our series. This finding does not seem to be clinically relevant as patients were asymptomatic and serum tumor markerswere normal in all cases. Furthermore, the hypoechoic area with calcifications resolved 1 year later in 2/3 patients. The absence of evolution of this finding seems to exclude the heteroplastic nature. We hypothesized that this finding may be linked to elevated volume and/or pressure of intratesticular injection. Future prospective study with larger series and longer follow-up is needed to assess long-term testicular outcomes. Laparoscopic Palomo varicocelectomy using ICG-FL reported excellent outcomes with low incidence ofvaricocele persistence and no post-operativehydrocele. These preliminary data also confirmed safety of intratesticular injection of ICG at mid-term follow-up, without specific risks for both testis and patient.

Non-invasive evaluation of testicular torsion using ultrasound shear wave elastography: an experimental study.

The goal of this study was to examine changes in testicular stiffness at various intervals after the induction of testicular torsion, as well as to assess the predictive value of testicular stiffness for testicular spermatogenesis after torsion. Sixty healthy male rabbits were randomly assigned to one of three groups: complete testicular torsion, incomplete testicular torsion, or control. All rabbits underwent preoperative and postoperative scrotal ultrasonography, including shear wave elastography (SWE), at predetermined intervals. Changes in SWE values were analyzed and compared using repeatedmeasures analysis of variance. To assess the diagnostic performance of SWE in determining the degree of spermatogenic function impairment, the areas under the receiver operating characteristic curves (AUCs) were calculated. SWE measurements in both central and peripheral zones of the testicular parenchyma affected by torsion demonstrated significant negative correlations with spermatogenesis, with coefficients of r=-0.759 (P<0.001) and r=-0.696 (P<0.001), respectively. The AUCs of SWE measurements in the central or peripheral zones of the torsed testicular parenchyma were 0.886 (sensitivity, 83.3%; specificity, 100%) and 0.824 (sensitivity, 83.3%; specificity, 73.3%) for distinguishing between hypospermatogenesis and spermatogenic arrest, respectively (P=0.451, DeLong test). Variations in the stiffness of both central and peripheral regions of the testicular parenchyma correlate with the extent and duration of torsion, exhibiting a specific pattern. The "stiff ring sign" is the characteristic SWE finding associated with testicular torsion. SWE appears to aid in the non-invasive determination of the extent of spermatogenic damage in torsed testes.
