A novel nomogram to predict testicular torsion in children with acute scrotal pain: a single-center retrospective study in western China. Transl Androl Urol 2024; 13:776-791. [PMID: 38855602 PMCID: PMC11157408 DOI: 10.21037/tau-23-634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 03/10/2024] [Indexed: 06/11/2024] Open
Abstract
Background Acute scrotal pain (ASP) is the most common urological emergency in pediatrics, and its causes include testicular torsion (TT), testicular appendage torsion, and epididymo-orchitis. Among them, TT requires prompt and accurate diagnosis and urgent surgical exploration to prevent testicular loss. Conservative anti-infective treatment is recommended for epididymo-orchitis, and surgery is considered only when scrotal abscess formation and sepsis occur. Improving the understanding of TT in primary care doctors, early diagnosis, and timely surgical exploration are essential to improve the survival rate of TT and avoid excessive treatment. This study aimed to explore the risk factors for TT in children with ASP and construct a predictive model. Methods Clinical data of children who presented with ASP and underwent emergency scrotal exploration surgery were retrospectively analyzed, including general information, physical examination, laboratory tests, and color Doppler ultrasonography (CDU) findings. Based on surgical exploration, the outcomes were categorized as confirmed TT or not. Results A total of 283 children were included in this study, among whom 134 had TT. The mean age of all patients was 105±47.9 months, with the majority being of Han ethnicity (87.6%) and residing in urban areas (83%). Most patients had normal C-reactive protein levels and negative results in urine routine white blood cell tests (63.3%). After conducting univariate and multivariate logistic regression analyses, we identified laterality, neutrophil count, mean erythrocyte sedimentation rate, epididymal blood flow signal, testicular parenchymal echogenicity, and testicular blood flow signal as independent risk factors influencing the occurrence of TT in ASP patients. Conclusions This study is the report with the largest sample size on the construction of prediction models for ASP in children in southwestern China. The predictive model we developed demonstrated excellent performance and higher accuracy in predicting TT in children compared to the traditional Testicular Workup for Ischemia and Suspected Torsion (TWIST) score. It can assist pediatric surgeons in diagnosing and treating children with ASP.

Hou J, Feng W, Liu Q, Wang Y, Guo Z, Liu W. Can we preserve the necrotic testis caused by incarcerated inguinal hernia in infants under 3 months? Pediatr Surg Int 2023; 40:16. [PMID: 38042759 DOI: 10.1007/s00383-023-05592-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/01/2023] [Indexed: 12/04/2023]
Abstract
PURPOSE This study aims to investigate whether necrotic testis resulting from incarcerated inguinal hernias can be preserved in infants under 3 months old. METHODS A retrospective analysis was conducted on data collected from infants under 3 months old who had necrotic testis caused by incarcerated inguinal hernias between 2016 and 2020. They were divided into two groups: the orchiectomy group and the testicular preservation group. The control group consisted of normal male children of the same age. Data regarding bilateral testicular volume, dihydrotestosterone, inhibin B, and antisperm antibodies were collected. RESULTS The study included 42 cases, with 18 patients being followed up for 6-54 months after the operation. In the testicular preservation group, 2 children did not experience testicular atrophy. There was no significant difference in the volume of the contralateral testes between the testicular preservation group and the control group; however, both groups had smaller testicular volumes compared to the orchiectomy group. There was no significant difference in the levels of inhibin B between the testicular preservation group and the orchiectomy group, although both were lower than the control group. Furthermore, no significant difference was observed in the levels of dihydrotestosterone and the positivity rate of antisperm antibodies among the three groups. CONCLUSION Preserving the necrotic testis may allow it to survive without impacting the contralateral testis. Therefore, a more conservative approach should be considered for orchiectomy when dealing with testicular necrosis caused by incarcerated inguinal hernias in infants.

Front Pediatr 2023; 11:1272659. [PMID: 37964816 PMCID: PMC10642505 DOI: 10.3389/fped.2023.1272659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 10/05/2023] [Indexed: 11/16/2023] Open
Abstract
Objective This study investigates the feasibility of the indocyanine green-guided near-infrared fluorescence (ICG-NIRF) imaging technique in evaluating testicular blood flow during testicular torsion (TT) surgery in pediatric cases. Methods We retrospectively analyzed the eight pediatric patients with TT who underwent surgery in our hospital between February and July 2023. The intraoperative two-step method of ICG-NIRF imaging and testicular incision was used to evaluate the testicular blood flow, followed by a selection of different surgical methods. The removed testes were pathologically examined after surgery, and all patients were followed up 1 month after surgery to evaluate testicular blood flow using gray-scale ultrasound and color Doppler flow imaging (CDFI). Results Eight pediatric TT patients aged 1-16 years, with a median age of 11.5 years, were enrolled. Time from the onset ranged from 4 to 72 h (mean 26.13 ± 25.09 h). A total of eight testes were twisted, including four on the left side and four on the right side. The twisting direction of the testes was clockwise in four cases and counterclockwise in four cases. The rotation of torsion was 180°-1,080° (mean 472.5° ± 396°). There was no statistically significant difference in the imaging time between the four patients with testicular blood vessel imaging on both the torsional and normal sides (P > 0.05). The postoperative recovery was uneventful, with no complications during the follow-up period of 1 month. The postoperative histopathological results of three patients who underwent orchiectomy showed extensive hemorrhage, degeneration, and necrosis of the testicular tissue. Among the five patients who underwent orchiopexy, a gray-scale ultrasound and CDFI examinations showed uniform internal echo of the testes and normal blood flow signals in four patients. One patient with no testicular blood vessel imaging on the torsional side showed uneven internal echo of the testis and no blood flow signals. Conclusion ICG-NIRF imaging is a feasible method to evaluate testicular blood flow during TT surgery. Testicular blood vessel imaging within 5 minutes after ICG injection might be the basis for testicular retention during TT surgery.

Is it time for a change of strategy? Andrology 2023; 11:1044-1049. [PMID: 36542416 DOI: 10.1111/andr.13368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 11/01/2022] [Accepted: 12/13/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND According to standard medical practice, immediate orchiectomy is advised in the case of a non-viable testis following testicular torsion. Because of the lack of objective criteria in the evaluation of testicular viability, the fate of the testis solely depends on the discretion and experience of the surgeon. OBJECTIVE In this study, we retrospectively reassess the management of patients with testicular torsion in our center, and we ask the question, from a retrospective point of view, of whether the decision to perform orchiectomy has always been correct. MATERIALS AND METHODS We retrospectively reviewed all cases of patients with testicular torsion who underwent surgery in our center between 2001 and 2021. All orchiectomy specimens were reevaluated and graded by an experienced pathologist using the Mikuz grading system. RESULTS Immediate orchiectomy was performed in 48 of the 136 patients (35%). Five (10.4%) of the 48 orchiectomy specimens were categorized as "grade 1," and 17 (35.4%) were categorized as "grade 2." The time between the onset of symptoms and surgical exploration exceeded 12 h in three of the five patients with a "grade 1" testicular injury, and in one case, it even exceeded 24 h. DISCUSSION "Grade 1" testicular injury is potentially reversible, whereas the fate of a testis with a "grade 2" testicular injury remains unknown. Whether and to what extent partial testicular tissue salvage in a "grade 2" injury is still possible remain unclear. CONCLUSIONS Our results indicate that at least 10% of the testicles removed in our center could, from a retrospective point of view, have been salvaged. Our study further demonstrated that the duration of symptoms is not an absolute indicator of testicular damage and that the decision of whether orchiectomy should be performed, based simply on the subjective macroscopic image of the affected testis, is not always correct.

Abstract
Objective To explore the clinical characteristics of testicular torsion in children with non-scrotal initial symptoms who were misdiagnosed. Methods A retrospective analysis of 73 cases children with testicular torsion and non-scrotal symptoms who were admitted to our department from October 2013 to December 2021 was performed. Patients were divided into misdiagnosis (27 cases) and clear diagnosis at first visit (46 cases) groups. Clinical data, including age at surgery, clinical presentation, physical examination, number of visits (≥2 times), affected side, time from initial symptoms to surgery, and surgical outcomes, were collected. The TWIST (Testicular Workup for Ischemia and Suspected Torsion) score was calculated and analyzed. Results Statistically significant differences between the misdiagnosis and clear diagnosis groups were seen in the time from initial symptoms to surgery, the number of visits, the degree of testicular torsion, and the rate of orchiectomy (P < 0.05). There were no statistically significant differences (P > 0.05) in age, affected side, TWIST score, guardian, direction of testicular torsion, intra-vaginal or extra-vaginal torsion, and Arda classification. Postoperative follow-up was 6-40 months. Of the 36 patients who required an orchiopexy, 1 had testicular atrophy at six months and 2 were lost to follow-up. The contralateral testis of the 37 children who underwent orchiectomies developed normally without torsion. Conclusions The clinical manifestations of testicular torsion in children are diverse and can easily lead to misdiagnosis. Guardians should be aware of this pathology and seek timely medical attention. When the initial diagnosis and treatment of testicular torsion is difficult, the TWIST score during the physical examination may be useful, especially for patients with intermediate-to-high risk scores. Color Doppler ultrasound can assist in making the diagnosis, but when testicular torsion is highly suspected, routine ultrasound is not necessary as it may lead to delayed surgical treatment.

Abstract
Spermatic Cord Torsion (SCT) is a serious surgical emergency. Prospective studies regarding the prognosis of the torsed testis lack in the global literature. Prompt diagnosis and treatment are crucial to increase the risk of saving the torsed testis. Testicular salvage can be predicted by the duration of symptoms, along with the degree of twisting and the ultrasound findings, regarding the homogeneity of the testicular parenchyma. The "golden window" to salvage the testicular function is suggested to be at 4-8 h, after the symptoms' onset. As the time passes, the ischemia is settled and the risk of necrosis is increased. It is generally accepted, that the possibilities of conducting orchiectomy are increased when not promptly intervening after the symptoms' onset. A few studies, tried to describe the impact of SCT on long- term fertility. The aim of this study is to collect them and elucidate with some general perceptions on this topic.

Abstract
OBJECTIVES To assess the risk of azoospermia development and the value of sperm retrieval in post-pubertal testicular torsion (TT). MATERIALS AND METHODS This prospective study included patients with post-pubertal TT. Surgical exploration was urgently performed with either orchiopexy or orchiedectomy and contralateral orchiopexy. With the intention of cryopreservation, all cases underwent conventional testicular sperm extraction. Patients were followed-up after 1, 3, and 6 months with semen analysis and hormonal assay (FSH, LH and testosterone). Sperm retrieval rate (SRR), azoospermia rate and changes in hormonal profile were evaluated. RESULTS The study included 62 patients with a median (IQR) age of 19 (18-20.7) years and duration of testicular torsion of 32.5 (18.3-48) hours. Testicular salvage was successful in 20 (32.3%) while orchiedectomy was performed on 42 patients. The duration of torsion [OR, 95% CI = 0.75 (0.61-0.93), P = .008] was the independent predictor of testicular salvage. Successful SR was achieved in 58 patients (93.5%); (40 from the affected testis and 18 from the contralateral side). After 6 months, 21 patients (33.8%) developed azoospermia [19 (45.2%) in orchidectomy group and 2 (10%) in orchiopexy group, P = .006]. Abnormal contralateral testis was the independent predictor of azoospermia [OR, 95% CI = 92(8.4-101.5), P < .001]. Azoospermia patients showed a statistically significant increase in FSH and LH and decrease in testosterone level as compared to the non-azoospermia group (P < .001). CONCLUSION Azoospermia is not rare in post-pubertal TT patients; therefore, SR at time of intervention seems to be a good option for them to preserve their fertility potentials.

Abstract
Background: This study investigates endocrine and exocrine testicular function, oxidative stress (OS) in semen, and erectile function in patients who underwent surgery for suspected testicular torsion (TT). Methods: We evaluated 49 patients over a mean follow-up of 101 months: n = 25 patients treated with surgical exploration, n = 20 patients treated with detorsion, and n = 4 treated with orchiectomy. We performed semen analysis including Male infertility Oxidative System (MyOxSIS) analysis, physical examination, and evaluation of endocrine and erectile function. Results: OS, erectile function and spermiogram categories did not differ significantly between the groups. The interval from the onset of symptoms to surgery differed significantly between groups (p < 0.001). Preservation of the testes was associated with a higher round cell count (p = 0.002) and follicle stimulating hormone (FSH, p = 0.003). OS showed a significant positive correlation with the spermiogram category (0.337; p = 0.022). A negative correlation was observed between OS and age (p = 0.033), sperm concentration (p < 0.001) and total sperm count (p = 0.006). Conclusions: Endocrine, exocrine and erectile function are not significantly affected by TT in the long term. Orchiectomy results in elevated FSH and a lower round cell count compared to preservation of the testis.

Testicular torsion: its effect on autoimmunisation, pituitary-testis axis and correlation with primary gonadal dysfunction in boys. Pediatr Res 2021; 90:1193-1200.

Abstract
BACKGROUND Torsion of the testis is an urgent surgical condition that endangers the viability of the gonad and the fertility of the patient. Our aim was to assess potential autoimmune processes and hormonal abnormalities in boys operated on due to that illness. METHODS The authors evaluated the levels of antibodies against sperm and Leydig cells, concentrations of follicle-stimulating, luteinizing and anti-Müllerian hormone, testosterone, oestradiol and vascular endothelial growth factor in the serum in 28 boys operated on due to torsion of the testis. Patients' sexual maturity was assessed according the Tanner scale (group G1, G4 and G5). RESULTS No antibodies against sperm or Leydig cells were found in the serum. Statistically significant differences in follicle-stimulating and anti-Müllerian hormone concentrations were observed in the G1, and they were higher in the study than in the control group. There were no statistically significant differences in luteinizing hormone, testosterone, oestradiol and vascular endothelial growth factor concentrations in the study group or control group. Testosterone concentration was unrelated to total testicular volume. CONCLUSIONS Results did not confirm the autoimmune process in boys with torsion of the testis. The pituitary-testis axis seems to have sufficient compensation capabilities. However, study results suggest that primary gonadal dysfunction may predispose to torsion. IMPACT Significant differences exist between the literature data and own results on the formation of antibodies and hormonal changes due to testicular torsion in boys. It is a novel, prospective study on antibodies against sperms and Leydig cells in the serum and on hormonal processes occurring as a result of the testicular torsion from the prenatal period to the adolescence with division into pubertal groups. The study has revealed sufficient compensation capabilities of the pituitary-testis axis and no autoimmune process in boys with torsion of the testis.
