ABSTRACT

Introduction: Perinatal testicular torsion is not a frequent, but a grave finding finding. As only immediate surgical retorsion may save the viability of the testicle, time is of essence. We report the case of a newborn where delayed diagnosis led to an unnecessary loss of one testicle. Presentation of Case: The newborn was presented one day after delivery with a swollen left blue scrotal pouch. The left testicle was little tender, higher in position and enlarged. Ultrasound revealed a globular, enlarged testicle left, showing hypodense necrotic areas within. Doppler sound could not detect any perfusion of the spermatic vessels. Scrotal fluid was present bilaterally. At operation, the testicle was considered unsalvageable, and left orchiectomy and right orchidopexy were performed. Discussion: In the newborn, it is more than convenient to perfom ultrasound of both testicles at the same time, which allows to compare texture and perfusion easily. Immediate surgical exploration should be performed at any time, even if in diagnostic doubt. The very most important step though is to professionally recognise and to react to this pediatric emergency, as time is of paramount essence. Conclusion: A case of a male newborn with unilateral perinatal testicular torsion is presented, where typical clinical signs and ultrasound features can be seen. Early exploration with orchiectomy of the necrotic testicle and orchidopexy of the healthy side may save the endocrine function and fertility.

1. INTRODUCTION

The testicles embryologically develop from the mesodermal bud proximal to the kidney, and usually find their way genetically determined into the scrotal pouch before birth or within the first months of life [1,2]. Spermatic cord torsion is a very rare event, and present in 1:7500 newborn [3]. A torsion occurring after, before or during birth, compromises the vascular supply up to full testicular necrosis with consequences tor fertility [3-5]. Immediately recognised, diagnosis can be easily proven noting the typical clinical appearance and characteristic ultrasound features [6]. As only immediate surgical retorsion may save the viability of the testicle, time is of essence. We report the case of a newborn where delayed diagnosis led to an unnecessary loss of one testicle.

2. PRESENTATION OF CASE

The newborn was presented to us one day after delivery in a small clinic. Transport time was less than one hour. At the time of birth his father had held his newborn son, inspected his private parts and noted a swollen scrotal pouch on the left side, which was slightly more bluish than the right side. Unfortunately, the midwife in charge did not react neither to his finding nor to her own inspection of the newborn. The following morning, after a routine examination by the attending doctor, transfer was arranged to our hospital, which comprises a large pediatric department, pediatric intensive care and surgical facilities.

On immediate examination, the affected left testicle was slightly tender, higher in position and enlarged with bluish color (Figure 1). The left testicle was of soft texture und not engorged.

Ultrasound revealed a globular, enlarged testicle on the left side, showing hypodense necrotic areas within (Figures 2 and 3). Doppler sound could not detect any perfusion of the spermatic vessels. Scrotal fluid was present bilaterally (Figure 4).

At operation, the spermatic cord looked viable but twisted (Figure 5), but left testicle was already decomposing ichorously, due to a full spermatic cord twist (Figures 6 and 7). The left testicle was considered unsalvageable, left orchiectomy and right orchidopexy were performed.

3. DISCUSSION

A case of a first male newborn with unilateral neonatal testicular torsion is presented, where typical clinical signs and ultrasound features could be seen. In spite of typical

clinical features of testicular torsion at birth and the father’s worried remarks, there was no prompt reaction taken by the responsible clinic.

Although there is no proof that the torsion was acquired during birth, which may be underlined by an already decomposing left testicle and a low level of pain, it may have been saved when still ischemic. If testicular torsion happens days before birth, the survival of the testicle is in real danger, depending on the degree of torsion and the time period of ischemia. Testicular torsion may happen fully or gradually, leaving testicles necrotic or ischemic. Diagnostic difficulties may arise if an undescended, intraabdominal testis torques before birth [7]. Ischemic organs may profit from conservative treatment, and regain full or near-full endocrine status [8,9]. This is especially important in the rare cases of bilateral torsion, where the danger of retarded development, slower body growth, missed puberty and infertility are common [10- 13].

Even if the attending personnel is in doubt if the higher standing, firm, enlarged testicle may be a hydatid cyst or a tumour, ultrasound in the skilled users’ hand may reveal the typical features of one globular testicle without perfusion, containing peripheral and/or central necrotic hypodense areas [4,14-17]. Bilateral scrotal fluid is typically present, but is not proof of bilateral disease as shown above.

In the newborn, it is more than convenient to perform ultrasound of both testicles at the same time (Figure 2). This allows comparison of texture and perfusion easily. Immediate surgical exploration should be performed already at suspicion of testicular torsion [6,18,19]. An ischemic testicle may be rotated back into position and pexied, whereas an overt necrotic one has to be removed [20].

We wish to emphasize, as shown in this case report, that the very most important step is early recognition and reaction to this pediatric emergency by surgical exploration, as time is of paramount essence.

4. CONCLUSION

A case of a male newborn with unilateral neonatal testicular torsion is presented, where typical clinical signs and ultrasound features can be seen. Early exploration with orchiectomy of the necrotic testicle and orchidopexy of the healthy side may save the endocrine function and fertility.
