PURPOSE
Assumed predictors for testis atrophy after acute torsion include intra-operative testis color, pain duration, and red
scrotal skin. We prospectively correlated these factors to testis atrophy.
MATERIAL AND METHODS
Children 2 months-18 years with acute scrotum were enrolled in a NIH study of trans-scrotal near infrared spectroscopy
as a diagnostic test for testicular torsion. Per study protocol, no orchiectomies were performed. Intra-operative testis
color 5 minutes after detorsion [photographic scale: 1-pink, 2-mottled pink, 3-light blue, 4-purple, 5-black, 6-
hemorrhagic/necrotic], pain duration, and presence/absence of red scrotal skin were recorded. Percent volume
difference between normal and affected testis on follow-up ultrasound was compared between patients with and without
risk factors.
RESULTS
Excluding 18 patients lost to follow up, 28 patients underwent ultrasound at mean 115 days (41-319) post-operatively.
Patients who had ≥80% torsed testicle volume loss included 100%(5/5) who had a 5 minute black/hemorrhagic color,
90%(9/10) with pain duration over 12 hours, and 60%(6/10) with preoperative red scrotal skin. Overall, there was no
significant difference in testicular volume loss between patients with and without red scrotal skin, Table 1.

CONCLUSIONS
Black/hemorrhagic testis 5 minutes after detorsion and pain greater than 12 hours were associated with testis
atrophy. Red scrotal skin was not a reliable predictor of future atrophy and is not a reason to delay exploration.
