Diagnostic efficacy and value of ultrasound in children's scrotal testicular torsion: A retrospective analysis.

The purpose of this study is to explore the diagnostic efficacy and value of ultrasound detection for testicular torsion in children with scrotal and testicular diseases. A total of 120 children with acute scrotal swelling and pain who were treated in our hospital from August 2017 to August 2022 were selected for preliminary diagnosis through color Doppler ultrasound diagnostic instrument examination. The final diagnosis was made through surgical or conservative treatment. At the same time, 40 children with acute epididymitis during the same period were selected as the control group, and the clinical treatment of patients with testicular diseases was retrospectively analyzed. A total of 120 children were diagnosed with testicular torsion disease, with 57 cases affecting the left testicle and 63 cases affecting the right testicle. Ultrasound examinations revealed no blood flow signal in 78 cases, a significant reduction in blood flow in 38 cases, and no change in 4 cases. Among the pediatric patients who underwent manual reduction, 79 cases had a favorable prognosis. Surgical reduction was performed in 41 cases, with 35 cases successfully treated and 6 cases resulting in testicular removal. Follow-up examinations conducted 6 months to 1 year postoperatively showed testicular atrophy in 4 out of 35 cases with preserved testicles, while the 6 cases that underwent testicular resection had good outcomes. The non-active subgroup had a longer disease course and a greater degree of torsion (P < .05). There was no statistically significant difference in testicular volume and the ratio of healthy testicular volume between the 2 groups (P > .05). The sensitivity of ultrasound diagnosis was 95.24% (73/77), specificity was 78.57% (34/43), and accuracy was 89.29% (107/120). Ultrasound can effectively diagnose testicular torsion and evaluate the success rate of testicular reduction. Early treatment of patients with testicular torsion leads to better efficacy and higher survival rates.

[Acute scrotum in children]. / ABC om Akut skrotum hos barn.

Acute scrotum in a child is common, and the main underlying conditions are torsion of intrascrotal appendages, epididymitis, testicular torsion and idiopathic scrotal edema. The main diagnostic aim is to confirm or rule out testicular torsion, since this may lead to irreversible ischemia within hours. The diagnostics can be difficult, especially in prepubertal boys, but consist of a thorough history and clinical examination, the use of a clinical prediction score, and sometimes ultrasound with doppler. However, none of these tools can with completely accuracy rule out a testicular torsion, and uncertainty should prompt an acute scrotal exploration. The treatment of a testicular torsion is detorsion and bilateral orchidopexy, or unilateral orchidectomy in case of a completely necrotic testicle. Treatment of the other underlying conditions is often only symptomatic, and follow-up is often not required.

Clinical features of neonatal testicular torsion: A retrospective analysis of 24 cases.

OBJECTIVES: To analyze the clinical characteristics, surgical management decisions, and outcomes of Neonatal testicular torsion (NTT) in order to offer guidance for future clinical practice. METHODS: Retrospectively analyzed the clinical data of patients with NTT who were admitted and underwent surgery from January 2008 to October 2023. RESULTS: A total of 24 neonates were enrolled in this study, all of whom were unilateral cases. Age of onset was 0 d (IQR: 0-1.8), while the median duration of symptoms was 73 h (IQR: 26-199). Clinical manifestation included enlarged scrotum (75 %), changes in scrotal color (79 %), and crying upon palpation (17 %). All patients underwent urgent bilateral exploration and performed by orchiectomy and contralateral orchiopexy. CONCLUSION: NTT primarily occurs prenatally with insidious manifestations, often leading to omission or misdiagnosis. The testicular salvage rate is extremely low. Physicians need to attach importance to neonatal testicular examination, improve the vigilance of NTT. Early bilateral exploration does not necessarily save the affected testes, but it is more important to prevent damage to the contralateral one.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

The ball's in your court: Trends, causes, outcomes, and costs of patient transfer for pediatric testicular torsion.

BACKGROUND: The transfer of pediatric patients with testicular torsion from community hospitals to pediatric centers can be a time and resource-intensive step toward emergent surgical intervention. OBJECTIVE: We sought to describe trends of patient transfer in our state and compare clinical outcomes and health system costs between patients transferred and treated primarily at a pediatric center. STUDY DESIGN: This retrospective cohort study compared patients aged 1-18 years who presented directly to a pediatric center to those transferred for acute testicular torsion from 2018 to 2023. Exclusion criteria included age <1 year, non-urgent surgery, and admission from clinic. Patient age, BMI, Tanner stage, ASA class, insurance coverage, and presentation time were covariates. Group characteristics and times from symptom onset to initial ED presentation to surgery were compared via two-sided Student's t-tests. Clinical outcomes (orchiectomy, testicular atrophy) were compared via Fisher's exact tests. Costs from transferring hospitals were estimated from costs at our institution, and medical transport costs were extrapolated from contract prices between transport agencies and the pediatric center to compare total episode-of-care cost. RESULTS: A total of 133 cases (37 primaries, 96 transfers) met inclusion criteria. Transfers increased over the study period (67%-75%). There were no significant differences in age, Tanner stage, ASA score, BMI, or time of day of presentation between groups. Median transfer distance was 12 miles (IQR 7-22) and time was 1 h (IQR 1-2). More than half of cases (53%) were transferred due to hospital policy regarding surgical treatment of minors, and 25% due to lack of urology coverage. Time from initial ED site to OR was nearly doubled for the transfer group (median 4.5 vs 2.5 h, p = 0.02). Despite a higher rate of orchiectomy in the primary group (43 vs 22%, p = 0.01), this difference was not significant after stratification by symptom duration. The estimated average cost of care for patients transferred was twice that of primary patients ($15,082 vs $6898). DISCUSSION: Transfer of pediatric patients in our state for testicular torsion has increased in recent years. Hospital policies and local urology coverage are primary drivers of patient transfer which nearly doubled time to surgical intervention and more than doubled cost of care. Clinical outcomes were driven by delayed presentation. CONCLUSION: Transfer of pediatric patients for testicular torsion nearly doubles time to surgical intervention and more than doubles cost of care. Restrictive hospital policies and gaps in rural hospital urology coverage present opportunities to improve the quality and efficiency of care for these children.

Clinical characteristics and outcome of children with acute cryptorchid testicular torsion: A single-center, retrospective case series study.

BACKGROUND: Cryptorchidism and testicular torsion (TT) are relatively common conditions in clinical practice; however, sparse information about cryptorchid TT is available in the current literature. METHODS: We retrospectively reviewed the clinical characteristics, treatment modalities, and long-term outcomes of pediatric patients treated for acute cryptorchid TT. RESULTS: We found eight patients with unilateral acute cryptorchid TT with a prevalence of 8.9% (8/90) among all TT cases. The left testis was affected in six patients. The median age of patients at the time of the surgery was 65 months (interquartile range (IQR) 4-136 months). The median duration of symptoms was 16 h (IQR 9-25 h), while the median time to treatment was 60 min (IQR 59-63 min). The most common symptoms were pain (abdominal and inguinal) and inguinal mass with no palpable testis in the ipsilateral hemiscrotum. Preoperative color Doppler ultrasonography revealed absent or decreased testicular blood flow in the affected testes in 7/8 of patients. Various degrees of testicular torsion (median 540°, min 360°, max 1260°) were found during surgery. A necrotic testis that led to orchidectomy was found in 4/8 of patients. The median follow-up period was 42.6 months (IQR 12.5-71.2 months), revealing only one patient with testicular atrophy. The final testicular salvage rate was 35%. CONCLUSIONS: Greater awareness among caregivers and primary care physicians about acute cryptorchid TT is required to improve their timely diagnosis and treatment. A physical examination of the external genitalia and inguinal regions should be mandatory to attain a proper diagnosis and treatment without delay.

The impact of health care on outcomes of suspected testicular torsion: results from the GRAND study.

BACKGROUND: Suspicion of testicular torsion represents a urological emergency, necessitating immediate surgery. Comprehensive data on the current trends and perioperative outcomes regarding surgical exploration are sparse. Therefore, we utilized nationwide data on the prevalence and results of this surgery, aiming to provide evidence on this matter. METHODS: We assessed the GeRmAn Nationwide inpatient Data (GRAND) from 2005 to 2021, provided by the Research Data Center of the Federal Bureau of Statistics. We performed multiple regression analyses to evaluate the perioperative outcomes (length of hospital stay, transfusion, and surgical wound infection) after surgical exploration due to suspected testicular torsion based on both the outcome of surgery (orchiectomy, detorsion with preservation of the testicle, and no testicular torsion) and on the department of operation (urological versus non-urological). RESULTS: A total of 81,899 males underwent surgical exploration due to suspected testicular torsion in Germany from 2005 to 2021. Of them, 11,725 (14%) underwent orchiectomy, 30,765 (38%) detorsion with preservation of the testicle and subsequent orchidopexy, and 39,409 (48%) presented no testicular torsion. Orchiectomy was significantly associated with longer length of hospital stay (day difference of 1.4 days, 95%CI: 1.3-1.4, p < 0.001), higher odds of transfusion (1.8, 95% CI: 1.2-2.6, p = 0.002) and surgical wound infections (1.8, 95%CI: 1.4-2.3, p < 0.001) compared to no testicular torsion. The proportion of patients undergoing orchiectomy was significantly lower in urological departments (14%) versus non-urological departments (16%) and the proportion of patients undergoing preservation of testicle after detorsion was significantly higher in urological departments (38%) versus non-urological departments (37%), p < 0.001. Patients undergoing treatment in a urological department were discharged earlier and presented lower odds of transfusion and surgical wound infection (p < 0.001) compared to patients undergoing treatment in a non-urological department. CONCLUSIONS: Nearly half of patients who underwent surgery for suspected testicular torsion did not have intraoperatively the condition confirmed. Patients treated in urological departments had significantly better perioperative outcomes compared to those treated in non-urological departments. Therefore, we advise to refer patients to urological treatment as early as possible.

Paediatric testicular torsion in low- and middle-income countries: an OxPLORE scoping study.

BACKGROUND: Literature on paediatric surgical conditions in low- and middle-income countries (LMICs) remains limited. As a common emergency, timely treatment of testicular torsion acts as a benchmark of adequate emergency service delivery in paediatric surgery. This scoping study aims to synthesise all existing literature on paediatric testicular torsion in LMICs. METHODS: A database search was conducted by the OxPLORE global paediatric surgery research group to identify studies containing the terms 'testicular torsion' or 'acute scrotum' originating from LMICs. A thematic analysis was applied to the results of the search and the quality of evidence was appraised for all included articles. RESULTS: This review included 17 studies with 1798 patients. All studies originated from middle-income countries and the majority (76%) had sample sizes smaller than 100 patients. All studies were appraised as providing less than adequate evidence. Included studies identified long delays to treatment and highlighted ongoing debates on the value of scoring systems and Doppler ultrasonography in diagnosing torsion. Major heterogeneity in surgical approaches to treatment of testicular torsion in children was also observed. CONCLUSIONS: Literature on paediatric testicular torsion in LMICs is scarce and heterogeneous. Prospective, multi-centre research on the management of this common paediatric surgical emergency is urgently required.

Orchiopexy: one procedure, two diagnoses - different male infertility outcomes.

ABSTRACT: Infertility, affecting one in six couples, is often related to the male partner's congenital and/or environmental conditions or complications postsurgery. This retrospective study examines the link between orchiopexy for undescended testicles (UDT) and testicular torsion (TT) in childhood and adult fertility as assessed through sperm analysis. The study involved the analysis of semen samples from 7743 patients collected at Soroka University Medical Center (Beer Sheva, Israel) between January 2009 and December 2017. Patients were classified into two groups based on sperm concentration: those with concentrations below 5 × 10 6 sperm per ml (AS group) and those above (MN group). Medical records and surgical histories were reviewed, categorizing orchiopexies by surgical approach. Among 140 individuals who had undergone pediatric surgery, 83 (59.3%) were placed in the MN group and 57 (40.7%) in the AS group. A higher likelihood of being in the MN group was observed in Jewish compared to Arab patients (75.9% vs 24.1%, P = 0.006). In cases of childhood UDT, 45 (78.9%) patients exhibited sperm concentrations below 5 × 10 6 sperm per ml ( P < 0.001), and 66 (76.7%) had undergone unilateral and 18 (20.9%) bilateral orchiopexy. Bilateral orchiopexy was significantly associated with lower sperm concentration, total motility, and progressive motility than unilateral cases ( P = 0.014, P = 0.001, and P = 0.031, respectively). Multivariate analysis identified UDT as a weak risk factor for low sperm concentration (odds ratio [OR]: 2.712, P = 0.078), with bilateral UDT further increasing this risk (OR: 6.314, P = 0.012). Jewish ethnicity and TT diagnosis were associated with a reduced risk of sperm concentrations below 5 × 10 6 sperm per ml. The findings indicate that initial diagnosis, surgical approach, and ethnicity markedly influence male fertility outcomes following pediatric orchiopexy.

Sex-based Disparities in the Management of Pediatric Gonadal Torsion.

INTRODUCTION: In 2015, the U.S. News and World Report (USNWR) implemented a quality metric to expedite surgery for testicular torsion (TT), but not ovarian torsion (OT). This study examined OR timing among children with suspected TT and OT before and after this metric. METHODS: A single-center retrospective cohort study of children (1-18yr) who underwent surgery for suspected gonadal torsion was performed. Time to OR (TTOR) from hospital presentation to surgery start was calculated. An interrupted time series analysis identified changes in TTOR for suspected TT versus OT after the 2015 USNWR quality metric. RESULTS: Overall, 216 patients presented with TT and 120 with OT. Median TTOR for TT was 147 min (IQR:99-198) versus 462 min (IQR:308-606) for OT. Post-quality metric, children with TT experienced a 27.8 min decrease (95% CI:-51.7,-3.9, p = 0.05) in annual median TTOR. No significant decrease was observed for children with OT (p = 0.22). Children with history of a known ovarian mass (N = 62) experienced a shorter TTOR compared to those without (422 vs 499min; p = 0.04). CONCLUSION: Implementation of a national quality metric for TT expedited surgical care for children with TT, but not children with OT. These findings highlight the need for equitable quality metrics for children presenting with suspected gonadal torsion. LEVEL OF EVIDENCE: III.

Surgical Management of Extravaginal Testicular Torsion in a 16-Year-Old Male: A Case Report.

Extravaginal torsion (EVT) is a rare type of testicular torsion that usually occurs in neonates. The primary type of testicular torsion that occurs in adolescents is intravaginal torsion. In this case report, we describe the first case of EVT reported in a 16-year-old male with a contralateral bell clapper deformity and subsequent surgical management using a tunica vaginalis flap and bilateral orchiopexy. In discussion of this case, we examine possible anatomical causes of EVT and suggestions for appropriate surgical management.

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

PURPOSE: Ultrasound 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. METHODS: Patients' 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. RESULTS: In 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. CONCLUSION: In a clinical setting, ultrasound provided a reliable tool for the diagnosis of testicular torsion and did not seem to increase the orchiectomy rate.

A nationwide epidemiological study of testicular torsion: Analysis of the Japanese National Database.

Testicular torsion is a severe urological emergency caused by the twisting of the spermatic cord. The nationwide incidence of testicular torsion in Japan has not been previously reported. Accordingly, we aimed to estimate the nationwide incidence of testicular torsion using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) and examine the orchiectomy rate. This cross-sectional study was based on data from the NDB. We extracted data of patients aged < 21 years with documented testicular torsion and relevant treatment from January 2018 to December 2020. Testicular torsion was identified based on the Japanese standardized disease codes. The national incidence rate between 2018 and 2020 was calculated and assessed according to age and region of origin. Orchiectomy rates were evaluated according to age. The nationwide incidence rates of testicular torsion were 14.46, 15.09, and 15.88 per 100,000 males aged < 21 years in 2018, 2019, and 2020, respectively. The orchiectomy rate was 7.1%. Testicular torsion was most frequently observed during winter. A similar trend was observed nationwide. To the best of our knowledge, this study is the first to report the nationwide incidence of testicular torsion in Japan.
