The aim of this study is to establish ventral glans length (VGL), meatus (M) size, and their ratio VGL/M (R) in normal Indian boys and to compare these with the respective equivalent dimensions in boys with distal and mid-penile hypospadias using anatomic landmarks.
Normal boys were designated as Group A ( = 108), and the boys with hypospadias were designated as Group B ( = 81). The anatomical landmarks marked on the glans were measured using a digital camera and appropriate software.
The mean age of the boys in Groups A and B was 4.26 ± 3.59 (range 0.5-12) and 3.82 ± 2.85 (0.7-11) years, respectively. The observed mean values in Group A for VGL-A, M-A, and R-A were 3.05 ± 1.27 (range 1.19-8.09), 4.3 ± 1.23 (range 1.61-7.04), and 0.8 ± 0.45 (range 0.27-2.1) mm, respectively. The observed mean values in Group B for VGL-B, M-B, and R-B were 3.77 ± 0.81 (range 12.41-5.2), 3.27 ± 0.71 (range 2.25-5.34), and 1.17 ± 0.26 (range 0.84-1.86) mm, respectively. Comparison of R-A and R-B showed a statistically significant difference ( < 0.0001).
The dimensions and the studied ratio between a hypospadiac glans and a normal glans differed significantly. The ratio between VGL and M was 0.8 in normal boys. In comparison, the ratio between the equivalent VGL and M in the hypospadiac boys was 1.17. During glansplasty in surgery for hypospadias, this factor should be taken into consideration to avoid the creation of long and tight ventral glans closure.
本研究旨在确定正常印度男孩的阴茎头腹侧长度(VGL)、尿道口(M)大小及其比值VGL/M(R),并使用解剖标志将这些指标与阴茎远端和中段尿道下裂男孩的相应等效尺寸进行比较。
正常男孩被指定为A组(n = 108),尿道下裂男孩被指定为B组(n = 81)。使用数码相机和适当软件测量阴茎头上标记的解剖标志。
A组和B组男孩的平均年龄分别为4.26±3.59岁(范围0.5 - 12岁)和3.82±2.85岁(0.7 - 11岁)。A组中VGL - A、M - A和R - A的观察平均值分别为3.05±1.27毫米(范围1.19 - 8.09)、4.3±1.23毫米(范围1.61 - 7.04)和0.8±0.45(范围0.27 - 2.1)。B组中VGL - B、M - B和R - B的观察平均值分别为3.77±0.81毫米(范围12.41 - 5.2)、3.27±0.71毫米(范围2.25 - 5.34)和1.17±0.26(范围0.84 - 1.86)。R - A和R - B的比较显示出统计学上的显著差异(P < 0.0001)。
尿道下裂阴茎头与正常阴茎头的尺寸及所研究的比值存在显著差异。正常男孩中VGL与M的比值为0.8。相比之下,尿道下裂男孩中相应的VGL与M的比值为1.17。在尿道下裂手术的阴茎头成形术中,应考虑这一因素,以避免形成过长且紧绷的阴茎头腹侧闭合。
