: Among men with Peyronie's disease (PD), the degree of penile curvature has significant implications on psychological well-being, sexual function, treatment planning, and posttherapy evaluations.
The primary objective of the current study was to correlate patients' estimates of penile angulation with objective measures.
(i) Proportion of patients over- or underestimating their actual degree of curvature; and (ii) degree differences between patient estimates and objective measures of penile curvature. Methods. At baseline, patients with established PD were asked to provide a "best estimate" of their degree of penile curvature. Objective measures of penile angulation were then performed using standardized photographs and protractor-based measurement of penile curvature during full erection. Correlations were performed between patient estimates of penile curvature and objective measures of penile angulation.
Eighty-one men with established PD and a mean age of 52 years (range: 20-72 years) were prospectively evaluated. Mean duration of disease was 33 months (range: 6-276 months), and mean plaque size was 1.4 cm +/- 0.1 standardized error (SE). The proportion of patients with dorsal, lateral, and ventral curvatures was 39%, 57%, and 4%, respectively. Patient estimates of baseline penile curvature (mean 51 degrees +/- 3.1 SE) differed significantly from objective measurements (mean 40 degrees +/- 2.4, P = 0.001). A significantly higher proportion of patients overestimate their actual degree of penile curvature (54% overestimate, 26% underestimate, and 20% are accurate within 5 degrees, P = 0.002). Compared with objective measures, patients' estimates of degree of penile curvature differed by an average of 20 degrees +/- 2.2 SE.
Patients with PD tend to overestimate their degree of penile curvature. Objective measurement of penile angulation is necessary to accurately counsel patients regarding disease severity, recommend appropriate treatment strategies, and objectively evaluate outcomes following therapy.
在佩罗尼氏病（PD）患者中，阴茎弯曲程度对心理健康、性功能、治疗方案规划及治疗后评估具有重要意义。
本研究的主要目的是将患者对阴茎角度的估计与客观测量结果进行关联。
（i）高估或低估其实际弯曲程度的患者比例；（ii）患者估计值与阴茎弯曲客观测量值之间的度数差异。方法。在基线时，要求确诊为PD的患者对其阴茎弯曲程度进行“最佳估计”。然后使用标准化照片和基于量角器的完全勃起时阴茎弯曲测量方法进行阴茎角度的客观测量。对患者阴茎弯曲估计值与阴茎角度客观测量值之间进行相关性分析。
对81例确诊为PD且平均年龄为52岁（范围：20 - 72岁）的男性进行了前瞻性评估。疾病平均持续时间为33个月（范围：6 - 276个月），平均斑块大小为1.4 cm±0.1标准误差（SE）。阴茎背侧、外侧和腹侧弯曲患者的比例分别为39%、57%和4%。患者对基线阴茎弯曲的估计值（平均51度±3.1 SE）与客观测量值（平均40度±2.4，P = 0.001）存在显著差异。显著更高比例的患者高估了其实际阴茎弯曲程度（54%高估，26%低估，20%在5度范围内准确，P = 0.002）。与客观测量相比，患者对阴茎弯曲程度的估计平均相差20度±2.2 SE。
PD患者往往高估其阴茎弯曲程度。对阴茎角度进行客观测量对于就疾病严重程度向患者提供准确咨询、推荐合适的治疗策略以及客观评估治疗后的结果是必要的。
