Timing and surgical management of neonatal testicular torsions

Abstract

Background The timing and surgical management of neonatal testicular torsions (NTTs) remain controversial, varying from immediate orchiectomy with empirical contralateral orchiopexy to expectant management with resulting atrophy of the affected testicle. The goal of the present study is to review the management of this entity at our institution. Materials and methods A retrospective study of all patients with NTT from 1989 to 2007 was undertaken. The age, clinical presentation, investigation, management, and short- and long-term outcomes were noted. Results Forty-four patients were included. Most presented with a firm testicular mass, scrotal discoloration, and hydrocele (42), whereas a few presented with testicular atrophy (2). The median age at presentation was 1 day of age (range, 0-84 days), with NTT occurring on the right side in 22 patients and the left side in 20. Two patients (5%) had bilateral torsion at presentation. In 33 patients, the diagnosis was confirmed by Doppler ultrasonography, whereas 11 patients did not undergo any additional investigation. Surgical management included ipsilateral orchiectomy and contralateral orchiopexy (IOCO) (27), orchiopexy of the contralateral testis (CO) (7), bilateral orchiopexy (4), orchiectomy of the ipsilateral testis (1), orchiopexy of the ipsilateral testis (2), and observation (1). The 2 bilateral torsions underwent bilateral orchiectomy (2). The median age at surgery was 25 days (range, 1-912 days). Postoperative complications occurred in 8 patients (18%), mainly in those with IOCO (4) and CO (4) operated before 12 days of age, and included recurrent hydrocele (3), wound infection (2), urinary tract infection (1), and others (2). Upon follow-up, patients who underwent CO developed ipsilateral testicular atrophy (6). No patients were readmitted for recurrence of torsion or other complications. Conclusion At our institution, the most frequent management of unilateral neonatal testicular torsions is IOCO or CO, but this carries an 18% complication rate, particularly if surgery is performed early. There seems to be no advantage to early intervention, and the need for orchiectomy is debatable because torsion leads to ipsilateral testicular atrophy. Contralateral orchiopexy done to decrease the incidence of bilateral asynchronous torsion should, at the very least, be deferred until the risks of anesthesia and surgery are improved, given its rarity. Given the fact that most patients underwent IOCO or CO, we cannot conclude which strategy is the best for neonatal testicular torsions. A prospective study is welcomed.
