A Survey of the Current Practice Patterns of Contralateral Testis Fixation in Unilateral Testicular Conditions

Abstract

To query the current contralateral testis fixation (CTF) practice patterns among pediatric urologists in different clinical situations that could result in monorchism. An online survey was sent to members of the Urology Section of the American Academy of Pediatrics. The survey included questions addressing CTF practice patterns in 14 clinical scenarios. Responses were anonymously submitted, blindly reviewed, and analyzed. Among 53 respondents, 62.3% had academic appointments and 73.6% had an exclusive pediatric urology practice. All participants agreed on CTF necessity in testicular torsion beyond the neonatal period. CTF was advocated by 84.9% in prenatal torsion, 96.2% in postnatal torsion, and 94.3% in delayed torsion presentation. Emergent intervention was favored by 64.4% in prenatal and 98% in postnatal torsion. Only 1 participant (1.9%) preferred CTF with a unilateral testicular tumor and 5 (9.4%) in trauma substantiating an orchiectomy. There was less consensus on CTF in torsed undescended testis (79.3% in prepubertal and 81.13% in postpubertal), testicular nubbin in a child (40.4%), palpable atrophic undescended testis (13.2%), and unilateral bell-clapper anomaly (47.2%). In situations other than torsion, lack of strong evidence was the commonest reason not to perform CTF. The majority of responding pediatric urologists currently performs CTF in neonatal torsion. Although there is a general consensus on CTF in testicular torsion outside the neonatal period, CTF remains controversial in other clinical situations, warranting further research. The decision for CTF should involve patients, parents, and treating physicians.
