Long-term impact of testicular torsion and its salvage on semen parameters and gonadal function

Impact of on-hours versus off-hours admission on outcome in pediatric patients with testicular torsion

OBJECTIVES

Testicular torsion (TT) is an emergency requiring timely surgery to prevent testicular loss. There is a lack of reports on the clinical significance of the time of admission (on-hours vs. off-hours) on the long-term surgical outcome of TT.

METHODS

We retrospectively reviewed all consecutive patients <18 years who were admitted to the hospital and treated for TT during the ten years. Patients were classified according to their admission time: weekday (on-hours), outside working hours, and weekends (off-hours). They were also classified based on their testicular outcome: salvaged and non-salvaged testis.

RESULTS

Seventy-two patients were included. Their median age was 14.2 years. Thirty-three patients (46 %) were admitted during on-hours, whereas 39 patients (54 %) were admitted during off-hours. Forty-three patients (59.7 %) required orchidopexy and, out of those, during the long-term follow-up, only 27 (37.5 %) had definitive testicular salvage. Forty-five patients (62.5 %) were with no testicular salvage. On-hours vs. off-hours admission had no impact on the clinical outcome (p = 0.25). However, significant differences in the duration of symptoms (DoS) between the orchidopexy and orchidectomy groups were observed (p < 0.001).

CONCLUSION

Testicular torsion is a time-dependent diagnosis, and any delay in treatment could cause testicular loss. Our data suggest that the DoS before admission, rather than the admission time, influences the testicular outcome. The efficient management of emergencies regardless of the time of day is a key factor for the reduced probability that admission timing affects outcomes.

Clinical and Laboratorial Evaluation of Male Infertility. A Detailed Practical Approach

Infertility, defined as the inability to achieve pregnancy after one year of unprotected, frequent sexual intercourse, is a global burden that affects approximately 15% of couples, or 190-230 million people worldwide, who are trying to start a family. The male contributes significantly, directly accounting for 30-35% and up to 52% of total couple infertility, affecting approximately 7-8% of all men. This work aims to present, in a didactic and objective way, a standardization of the initial steps toward a thorough evaluation of subfertile and infertile men. We have focused on the evaluation of initial management, emphasizing the need for a comprehensive evaluation that includes a detailed history, physical examination, and semen analysis as the golden triple helix of basic evaluation of the infertile male. General and genital physical examinations are highly valuable due to the wealth of information they provide, from potential diagnoses to pregnancy prognoses. Comprehensive and quality-controlled semen analysis provides reliable information as a baseline test to evaluate the patency of the reproductive tract and to evaluate basic sperm parameters and fertility potential. However, it is not a fertility determinant and should preferentially be complemented with sperm functional tests. like biomarkers of oxidative stress, sperm immaturity and DNA fragmentation. Most cases of infertility require evaluation by a specialist in andrology, nonetheless the understanding and rationale of the initial assessment of the infertile male can be undertaken by non-specialists, thus improving the care and counseling of couples facing this troubling issue and avoiding unnecessary use of assisted reproductive technologies (ART) since most cases of male infertility can be treated and reversed by medical or surgical interventions, and the fertility status can be restored. The ultimate goal is to achieve natural pregnancy, the use of ART should not be the initial offered resource.

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.

Testicular Traction Technique with Intact Cremasteric Reflex, a Novel Approach for Manual Detorsion: Case Report

Introduction

Recognizing testicular torsion is extremely important in patients presenting to the emergency department (ED) with acute scrotal pain. Traditional manual detorsion techniques are frequently employed by emergency physicians but are not always successful. Delays in detorsion increase the risk of testicular infarction and infertility, and the need for orchiectomy. Novel techniques such as the testicular traction technique have been described as a potential solution for difficult-to-detorse testicles.

Case Report

Our case report describes a 20-year-old male with no significant past medical history who presented to a rural ED with acute, atraumatic testicular pain secondary to testicular torsion with an intact cremasteric reflex. After confirming the diagnosis using Doppler ultrasound, manual detorsion using the traditional "open book" technique was attempted and unsuccessful. The patient was subsequently successfully detorsed using the novel testicular traction technique.

Conclusion

The testicular traction technique is a safe, rapid, and effective primary or adjunctive technique in manual testicular detorsion. Given the time-sensitive nature of testicular torsions, adjunctive techniques play a crucial role in managing challenging detorsions, particularly in resource-limited rural settings with limited access to urologic services. Although it is commonly thought that the cremasteric reflex is absent in testicular torsions, it may be present in rare circumstances, and its presence should not be an absolute in ruling out torsion.

Varicocele and testicular cord torsion: immune testicular microenvironment imbalance

The main functions of the testis, steroidogenesis and spermatogenesis, depend on the endocrine axis and systemic and local tolerance mechanisms. Infectious or non-infectious diseases may disturb testicular immune regulation causing infertility. Literature has illustrated that bacterial and viral infections lead to autoimmune infertility: either sperm antibodies or autoimmune epidydimo-orchitis. However, little is known about the association between non-infectious testicular pathologic diseases and autoimmunity. Here we review the novel aspect of varicocele and testicular cord torsion pathology linked to inflammation and discuss how immune factors could contribute to or modulate autoimmunity in ipsi- and contralateral testis.

Rare Case of Managing and Evaluating Viability after Replantation of a Serial Self-Amputated Bilateral Testis by a Patient with Schizophrenia: A Case Report

Amputation of the testis is very rare in clinical situations; therefore, most surgeons have no experience with an amputated testis. In this case, a 31-year-old male with schizophrenia amputated both testes due to self-mutilation. We performed replantation surgery via microscopy. On postoperative day 1, he removed his right testis by using his hand, even though his hands were restrained. The second attack disrupted the viability of the right testis. However, after proper management, we checked the normal sex hormone level by preserving the replanted left testis. We evaluated the viability of the replanted testis by performing five examinations, namely, intraoperative indocyanine green injection, testicular scan with technetium pertechnetate, contrast-enhanced computerized tomography, Doppler ultrasonography, and serum testosterone level. In this report, we aimed to describe our rare experience about management with replantation of the amputated testes and evaluation of their viability.

Criteria for Preserving Grossly Ischemic Torsed Testicles Using Indocyanine Green Fluorescence Imaging: A Single-Center Case Series

Testicular torsion (TT) is a surgical emergency requiring early diagnosis and surgical intervention to avoid testicular loss. We report 3 pediatric TT cases with testicular salvage to visualize the blood flow by indocyanine green fluorescence imaging (ICG-FI) on the tunica albuginea of the testis. ICG-FI could not confirm blood flow in the testicular parenchyma; however, it could be detected in postoperative ultrasonography. Blood visualization of the tunica albuginea by ICG-FI may have potential criteria for testicular salvage. Long-term follow-up investigations after testicular salvage are needed to conclude the ICG-FI efficacy for TT.

Protective Effects of Syringic Acid on Ischemia-Reperfusion Injury in Testicular Torsion: An Experimental Study in a Rat Model

AIM

The purpose of this study was to assess the effectiveness of syringic acid in preventing ischemia-reperfusion injury following detorsion in a rat model of induced testicular torsion.

MATERIAL AND METHODS

In our study, a total of 24 rats, eight in each group, were used. Group 1 served as the control group. Group 2 underwent testicular torsion and detorsion. Group 3 underwent the same procedures as Group 2, but also received 100 mg/kg syringic acid immediately following ischemia. Spectrophotometric analysis was performed on blood samples, and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), as well as the values of malondialdehyde (MDA), were evaluated under direct microscopic examination of the testis to determine tissue injury. The architecture of the seminiferous tubules and spermatogenesis processes were graded using the Johnsen and Cosentino scoring systems.

RESULTS

The mean value of MDA was higher in Group 2 compared to the other groups (p < 0.001). Group 3 demonstrated a decline in the concentrations of proinflammatory cytokines, such as tumor necrosis factor-alpha, interleukin-6, and interleukin-1 beta, as indicated by biochemical analysis of blood samples, when compared to Group 2 (p-values: 0.045, 0.001, and <0.001, respectively). In addition, the improvement in Johnsen and Cosentino scores was significantly higher in Group 3 compared to Group 2 (p = 0.028 and p = 0.001, respectively).

CONCLUSION

These findings suggest that syringic acid has a protective effect against testicular oxidative damage.

Clinical characteristics and identification of risk factors of testicular torsion in children: A retrospective study in a single institution

Background

Testicular torsion (TT) is a common urological emergency posing serious health problem in children. Prompt diagnosis and treatment of TT are very important for children to protect the affected testis. The aim of this study was to evaluate the historical features, physical examination findings, laboratory tests, and ultrasound examinations in children with TT, as well as to identify the predictors of testicular salvage in children.

Materials and methods

We conducted a retrospective record of clinical findings, laboratory data, ultrasound findings, operating results, and the results of follow-up in hospitalized children with TT from November 2004 to December 2021. A multivariable logistic regression model was used to identify predictors of testicular salvage.

Results

A total 102 hospitalized children who presented with TT were included. Patients were aged from 1 month to 16 years, with a median age of 7.71 years. TT is significantly more common in the winter. Of these patients, 77 torsions were left-sided, 24 were on the right side, and only 1 was on bilateral sides. Meanwhile, we detected that 88 children suffering from TT had intravaginal torsion of the spermatic cord, and the rest were outside. Anticlockwise torsion was found in 65 cases (63.73%) and clockwise torsion in 37 (36.27%). As a result, 60 underwent orchidectomy, while 42 had a scrotal exploration with fixation of the testis. Multivariate analysis showed that cause of TT, time to intervention, white blood cell (WBC), and mean platelet volume (MPV) were correlated with the risk of a surgical outcome.

Conclusion

Only a small proportion of TT children received timely surgical management. Testicular salvage can be predicted by cause of TT, time to intervention, WBC, and MPV. Early scrotal exploration based on careful physical examination decreases the risk of misdiagnosis of spermatic cord torsion. A certain percentage of children with TT presenting with scrotal trauma or epididymo-orchitis should have their testicles checked to make sure that they do not have torsion, especially those who visit in the cold season.
