To determine the incidence of isolated neonatal penile glanular torsion, describe the basic characteristics, and explore the relationship between foreskin and glans torsion.
A prospective survey was conducted of all male newborns admitted to nursery after delivery, or neonates less than 3 months presenting for circumcision. Cases with associated genital malformations were excluded.
The incidence of isolated neonatal penile torsion was 27% (95% CI: 22.2%-31.84%), to the left in 99% of cases. In 3.5% of cases, the penis had an angle <10 degrees, and 9.5% >20 degrees. Using Spearman's correlational coefficient, deviation of penile raphe from the midline at the foreskin tip had a better correlation with glans torsion than deviation of raphe at the coronal sulcus (0.727 vs 0.570; both significant at p<0.01).
Isolated neonatal penile torsion is more common than reported. The median raphe of the penis may be normal and mask unexpected glans torsion. Median raphe torsion at foreskin tip can be used as a predictor for glans torsion. Clinical significance and relation to adult penile torsion are beyond the scope of the study.
确定孤立性新生儿阴茎头扭转的发生率，描述其基本特征，并探讨包皮与阴茎头扭转之间的关系。
对所有分娩后入住新生儿病房的男婴或小于3个月前来接受包皮环切术的新生儿进行前瞻性调查。排除伴有生殖器畸形的病例。
孤立性新生儿阴茎扭转的发生率为27%（95%可信区间：22.2%-31.84%），99%的病例向左扭转。3.5%的病例阴茎扭转角度<10度，9.5%的病例>20度。使用Spearman相关系数，包皮尖端阴茎缝偏离中线与阴茎头扭转的相关性比冠状沟处阴茎缝偏离更好（0.727对0.570；两者在p<0.01时均具有显著性）。
孤立性新生儿阴茎扭转比报道的更为常见。阴茎中线可能正常，掩盖了意外的阴茎头扭转。包皮尖端中线扭转可作为阴茎头扭转的预测指标。临床意义以及与成人阴茎扭转的关系超出了本研究范围。
