Neonatal bilateral testicular torsion: A plea for emergency exploration

Purpose: Bilateral testicular torsion is a rare condition. Most authors present single case reports. Therefore, the clinical and surgical aspects of bilateral torsion in a neonate have not been subjected to detailed analysis. We performed a retrospective analysis of our experience in the management of bilateral perinatal torsion as well as a collective review of the medical literature. Materials and Methods: All cases of neonatal testicular torsion managed at our neonatal surgical center during the last 2 decades (1986 to 2005) were reviewed, and 3 cases of bilateral torsion were identified. In addition, 45 neonatal cases of bilateral torsion were found through the literature search. In all cases data regarding clinical presentation, imaging studies, surgical management, intraoperative and pathological findings, and final outcome were analyzed. Results: Synchronous torsion occurred in 32 of 48 newborns (67%), while asynchronous pathology was reported in 16 (33%), including the 3 presented in this report. All except 1 patient were full-term newborns with normal or above average birth weight. Difficult delivery was noted in 33% of the cases. Despite prompt surgical intervention in 46 infants, the salvage rate was low, with arterial flow confirmed postoperatively in only 3 gonads (3.1%). Four gonads in 3 additional patients were reported to be of normal size on followup. Conclusions: Asynchronous torsion is not as rare an event as previously reported, and it may pose a diagnostic challenge. In the majority of these cases torsion of the left testis seems to occur later than torsion of the right testis. The role of imaging studies in newborns with bilateral torsion seems to be limited, especially in cases of asynchronous pathology. Urgent bilateral exploration is strongly advised in all newborns presenting with either unilateral or bilateral torsion. Such policy carries diagnostic, potential therapeutic and prognostic implications.
