Abstract：
OBJECTIVE: The pudendal nerve is an anatomical structure arising from the ventral branches of the spinal roots S2-S4. Its complex course may be affected by surrounding structures. This may result in irritation or entrapment of the nerve with subsequent clinical symptoms. Aim of this study is to review the anatomy of the pudendal nerve and to provide detailed photographic documentation of the areas with most frequent clinical impact which are essential for surgical approach.
METHODS: Major medical databases were searched to identify all anatomical studies investigating pudendal nerve and its variability, and possible clinical outcome of these variants. Extracted data consisted of morphometric parameters, arrangement of the pudendal nerve at the level of roots, formation of pudendal nerve, position according to sacrospinal and sacrotuberal ligaments and its terminal branches. One female cadaver hemipelvis was dissected with common variability of separate course of inferior rectal nerve. During dissection photodocumentation was made to record course of pudendal nerve with focus on areas with recorded pathologies and areas exposed to iatrogenic damage during surgical procedures.
RESULTS: Narrative review was done to provide background for photodocumentation. Unique photos of course of the pudendal nerve was made in areas with great clinical significance.
CONCLUSIONS: Knowledge of anatomical variations and course of the pudendal nerve is important for examinations and surgical interventions. Surgically exposed areas may become a site for iatrogenic damage of pudendal nerve; therefore, unique picture was made to clarify topographic relations.

摘要：
目的：阴部神经是由脊根S2-S4的腹侧分支产生的解剖结构。其复杂的路线可能会受到周围结构的影响。这可能导致神经的刺激或压迫，随后出现临床症状。这项研究的目的是回顾阴部神经的解剖结构，并提供对手术方法至关重要的最常见临床影响区域的详细摄影文件。
方法：搜索主要医学数据库，以确定所有研究阴部神经及其变异性的解剖学研究，以及这些变异可能的临床结果。提取的数据包括形态参数，阴部神经在根部的排列，阴部神经的形成,根据骶脊髓和骶结节韧带及其末端分支的位置。解剖了一个女性尸体半骨盆，其直肠下神经的不同过程具有共同的变异性。在解剖过程中，进行了照相记录以记录阴部神经的过程，重点是已记录病理的区域和外科手术期间暴露于医源性损伤的区域。
结果：进行了叙事回顾，以提供照片文档的背景。在具有重要临床意义的区域制作了阴部神经过程的独特照片。
结论：了解阴部神经的解剖变异和病程对于检查和手术干预非常重要。手术暴露区域可能成为阴部神经医源性损伤的部位；因此，制作了独特的图片来阐明地形关系。
