Abstract

Neonatal testicular torsion, also known as perinatal testicular torsion is a subject of debate among surgeons. Neonatal testicular torsion either intrauterine or postnatal results into extravaginal torsion which is a different entity than intravaginal type but has the same devastating consequences if not diagnosed and managed well in time. Testicular torsion results into acute ischemia with its resultant sequelae such as abnormality of testicular function and fertility. Urgent surgical exploration and fixation of the other testis are the key points in the management. General anesthesia is not a contraindication for exploration as thought before. Diagnosis and controversies on management of testicular torsion are discussed in this review.

Gray-scale and color Doppler sonography of scrotal disorders in children: an update.

Celestino Aso, Goya Enríquez, Marta Fité … (2015)

Ultrasonography (US) is well suited to the study of pathologic conditions of the scrotum in children. US provides excellent anatomic detail; when color Doppler and power Doppler imaging are added, testicular perfusion can be assessed. Gray-scale, color Doppler, and power Doppler US were used to study a spectrum of scrotal disorders in 750 boys aged 1 day to 17 years. The entities studied included processus vaginalis-related disorders (cryptorchidism, inguinal-scrotal hernia, and hydrocele); varicocele; acute scrotum (epididymo-orchitis, torsion of the testicular appendages, and testicular torsion); scrotal tumors; testicular microlithiasis; scrotal trauma; and systemic diseases with scrotal involvement. When combined with the results of clinical and physical examination, the information obtained with US is sufficient to enable diagnosis in most cases of scrotal disease. Moreover, color Doppler imaging is essential for differentiation between processes such as epididymo-orchitis or torsion of the testicular appendages and testicular torsion, which have similar clinical manifestations (pain, swelling, and redness) but are managed differently.

Neonatal torsion: a 14-year experience and proposed algorithm for management.

Jonathan D Kaye, Selwyn B Levitt, Steven Friedman … (2008)

Management of neonatal torsion is controversial, since the likelihood of testicular salvage and metachronous contralateral torsion must be weighed against the risk of neonatal anesthesia. We reviewed a large series of such cases and stratified neonatal torsion based on time of presentation to determine the potential for testicular salvage. To our knowledge this is the largest series of its kind in the literature. All cases of neonatal torsion were classified as either prenatal (noted at the time of delivery) or postnatal (noted after birth and before age 1 month). The charts of all patients were reviewed and data were collected on demographic information, pregnancy and birth history, laterality, physical examination findings, radiological imaging, intraoperative findings, anesthetic morbidities, perioperative complications and pathological diagnoses. Followup data were also collected for patients who underwent detorsion and orchiopexy. A total of 16 neonatal torsions (right side 8, left side 6, bilateral 1) were diagnosed in 15 patients at our institution between 1993 and 2007. A total of 13 torsions (81%) were prenatal and 3 (19%) were postnatal. All 13 prenatal torsions (100%) resulted in infarction (right 7, left 4, bilateral 2) confirmed by pathological examination. All patients underwent testicular exploration via an inguinal approach. A total of 11 cases were managed by orchiectomy at an average of 7.6 days (range 0 to 37) following birth. One of the bilaterally torsed testes showed infarction and necrosis on biopsy, and was detorsed and fixed in place. A second prenatally torsed testis was detorsed and pexed but atrophied on followup. Among the 3 postnatal torsions 1 (33%) was deemed viable on exploration and, therefore, salvaged. Of the 10 prenatal torsions with known prenatal history 5 (50%) were associated with at least 1 significant prenatal complication. Nine of the 10 patients with prenatal torsion (90%) were delivered vaginally, and 1 by cesarean section after prolonged failure of descent. Complicated pregnancies and vaginal deliveries seem to predispose patients to testicular torsion. Contrary to previous series, neonatal torsions do not appear to favor one side or the other. Prenatal torsions are never salvageable, and, therefore, do not warrant emergent intervention. Postnatal torsions are sometimes salvaged, and a judicious approach to surgical exploration should be taken.

Management of perinatal torsion: today, tomorrow or never?

Elizabeth Yerkes, Frank M Robertson, Jordan Gitlin … (2005)

Management of perinatal testicular torsion is a highly controversial issue. Despite uncommon salvage of the affected gonad, exploration for ipsilateral orchiectomy and empiric contralateral orchiopexy have been recommended due to the unlikely but unfortunate possibility of asynchronous torsion. Observation with serial examination is the alternative. Risk of general anesthesia must be weighed against the risk of anorchia. We describe our collective experience with bilateral perinatal torsion, solidifying our recommendation for early exploration in all cases of perinatal torsion. All cases of perinatal torsion from 3 practices during a 3-year period were reviewed. All practices were at an academic center or in a major metropolitan area. Early exploration for contralateral orchiopexy was performed in all cases. In 18 patients examination was consistent with unilateral perinatal torsion. Contralateral torsion was discovered at the time of exploration in 4 cases (22%). Despite orchiopexy of the better perfused gonad, atrophy was universal in these 4 cases. Findings potentially related to contralateral torsion were identified in 2 additional cases. No anesthetic or operative complications occurred. Bilateral asynchronous perinatal torsion is an uncommon but serious event. In our experience torsion of the contralateral gonad was not associated with signs or symptoms of acute torsion. Observation and serial examinations are then a challenging proposition. Due to the consistently poor outcome from bilateral asynchronous torsion, we continue to recommend early exploration and empiric contralateral orchiopexy for all cases of perinatal torsion. Parents must be counseled regarding the relative risks of exploration and anesthesia versus observation.
