Delaying Urgent Exploration in Neonatal Testicular Torsion May Have Significant Consequences for the Contralateral Testis: A Critical Literature Review

Neonatal Testicular Torsion with Hydrocele: A Case Report Underscoring the Need for Early Recognition and Management

Neonatal testicular torsion (NTT) is a rare but significant condition occurring within the first 30-day postbirth, leading to vascular compromise and potential testicular loss. This paper presents a case of NTT detected incidentally in a neonate with bilateral hydrocele, emphasizing the challenge of early diagnosis and management complexities. The infant underwent surgical intervention involving detorsion and bilateral orchiopexy but eventually required right orchiectomy due to necrosis. The paper highlights the prevalence of NTT in conjunction with hydrocele and stresses the importance of parent education and vigilant follow-up. Various diagnostic methods, primarily ultrasonography, and a range of management strategies are discussed, considering factors such as salvage potential, risk to the contralateral testicle, and surgical intervention's risks and benefits. The paper argues for individualized management, taking into account specific neonate conditions and parental preferences, underlining the essential role of informed and empathetic consultation. The case reinforces the urgent need for increased awareness, early detection, and carefully considered therapeutic approaches to prevent devastating outcomes like infertility and the necessity for lifelong hormone supplementation.

Ultrasonographical features of perinatal testicular torsion: an assessment of interobserver variability among radiologists and pediatric urologists

PURPOSE

To retrospectively compare interpretations of Doppler ultrasound (US) in newborns with confirmed perinatal testicular torsion (PTT) by an experienced faculty (staff) pediatric radiologist (SPR), pediatric radiology fellow (PRF), pediatric urology fellow (PUF) and staff pediatric urologist (SPU).

METHODS

US images of 27 consecutive males with PTT between May 2000 and July 2020 were retrieved. The testicles were classified as affected or non-affected by PTT. We performed a blinded comparison of interpretation by four assessors (SPR, PRF, PUF, SPU), with respect to the US features of PTT. Paired inter-rater agreement was calculated using Cohen's Kappa (κ) and overall agreement was assessed using Fleiss' kappa.

RESULTS

Overall comparison using Fleiss' kappa found fair agreement for most features except testicular echogenicity and echogenic foci at interface for which there was poor agreement. Paired comparisons revealed better agreement between the SPR and PRF compared to the remaining two pairs, suggesting a need for the pediatric urologists (PUF and SPU) to acquaint themselves with testicular ultrasonography as this may have an impact on patient risk stratification and the quality of information given to parents.

CONCLUSION

This study highlights the need for focused training program for pediatric urologists to attain similar agreement as the radiologists, suggesting a need for the pediatric urologists (PUF and SPU) to acquaint themselves with testicular ultrasonography as this may have an impact on patient risk stratification and the quality of information given to parents.

Perinatal Testicular Torsion in Northern Ireland: A Nationwide 10-Year Review

INTRODUCTION

 Perinatal or neonatal testicular torsion (PTT) is defined as testicular torsion within the first 30 days of life. PTT is a rare event, and bilateral PTT is even rarer. However, recent articles have advocated emergency bilateral exploration to exclude the catastrophic possibility of asymptomatic contralateral testicular torsion leading to anorchia. The aim of this study is to evaluate PTT in Northern Ireland (NI) using a nationwide population-based retrospective observational study.

METHODS

 All boys in NI who underwent emergency scrotal exploration within their first 30 days of life for possible testicular torsion over a 10-year period (January 2010-December 2019 inclusive) were included. Intraoperative findings primarily evaluated included diagnosis and presence of synchronous or asynchronous (metachronous) contralateral testicular torsion. Secondary outcomes included correlation between intraoperative findings and any preoperative ultrasound scan (USS), and scrotal examination findings during postoperative outpatient follow-up.

RESULTS

 A total of 19 patients who underwent emergency scrotal exploration in the study period were included. An intraoperative finding confirming the diagnosis of PTT was reported in 14 (73.7%) patients. The incidence of PTT was calculated as 11.3 per 100,000 per male live births in NI, with bilateral PTT accounting for two patients (14.2% of all PTTs), divided equally between synchronous and asynchronous PTTs. Of two affected testes where preservation was felt appropriate intraoperatively, only one was still palpable at follow-up, producing a testicular salvage rate after PTT of only 7.1%. Testicular findings on preoperative USS were confirmed intraoperatively in five out of six patients, producing a concordance rate of 83.3%.

CONCLUSION

 This is the first nationwide population-based study to calculate more accurately the incidence of PTT, and bilateral synchronous and asynchronous bilateral PTTs, all of which seem to be significantly higher than previously estimated. However, in keeping with previous reports, this study confirms the poor salvage rate of testes undergoing perinatal torsion, and suboptimal concordance between preoperative USS findings and intraoperative diagnosis.

Perinatal testicular torsion: The clear cut, the controversial, and the "quiet" scenarios

BACKGROUND

Perinatal testicular torsion (PTT) is a catastrophic event that occurs in utero or up to 30 days postnatally, with testicular loss being the most common outcome.

OBJECTIVE

To assess clinical evaluation, surgical management and clinical outcomes in patients with PTT in a quaternary referral pediatric center, to determine testicular salvageability and propose future management options.

METHODS

We retrospectively reviewed a cohort of males born outside the quaternary center with a diagnosis of PTT, from May 2000 to July 2020. Data collection included mode of delivery, gestational age, birth weight, testicular examination at birth, clinical presentation, ultrasound results at diagnosis, surgical management and findings, perioperative complications, and follow-up.

RESULTS

62 patients, including 2 patients with bilateral asynchronous PTT, were identified. Median (IQR) gestational age and birth weight were 39 (38-39.4) weeks and 3.4 (3.1-3.72) kg, respectively. Abnormal testicular examination at birth was found in 69% (Table 1). Doppler ultrasound was performed in all but 1 patient. 59 patients underwent surgery, 21 within 4 h, with bilateral exploration in 44 cases. Affected and non-affected testicles were explored in 76% and 98% of cases, respectively. 3 "nubbins" were found, of which 2 were excised. 3 nonsurgical complications were identified. During a median (IQR) follow-up of 3 (3-3) months, 63 testicles were removed or found to be non-functional, with compensatory hypertrophy in 38% of patients.

CONCLUSION

Given that 3% of our patients presented with asynchronous bilateral PTT, as well as the safety of general anesthesia in a referral pediatric hospital, early bilateral scrotal exploration of PTT is recommended.
