. To analyze the penile and urethral meatus biometry and its correlation with meatoplasty during endoscopic resections. We also propose a new classification for urethral meatus morphology. . We prospectively studied 105 patients who underwent prostate and bladder transurethral resections. We performed standardized measurement of penile and urethral meatus biometry followed by penile photo in the front position. The need to perform meatoplasty or dilatation during resectoscope introduction was registered. Data were analyzed comparing the correlation between two groups: without intervention (Group A) and with intervention (Group B). . We observed in Group A and Group B, respectively, the average length of urethral meatus of 1.07 cm versus 0.75 cm ( < 0.001) and average width of urethral meatus of 0.59 cm versus 0.38 cm ( < 0.001). Considering the morphology of the urethral meatus, we propose a new classification, in the following groups: (a) typical; (b) slit; (c) point-like; (d) horseshoe; and (e) megameatus. The point-like meatus was the one that most needed intervention, followed by the slit and the typical meatus ( < 0.001). . Point-like and slit-shaped urethral meatus, as well as reduced length and width of the urethral meatus, are the determining factors.
分析阴茎和尿道口生物测量及其在内镜切除术中与尿道口成形术的相关性。我们还提出了一种新的尿道口形态分类法。我们前瞻性地研究了105例行前列腺和膀胱经尿道切除术的患者。我们对阴茎和尿道口进行了标准化测量，随后拍摄阴茎正面照片。记录在插入电切镜时是否需要进行尿道口成形术或扩张术。对两组数据进行分析，比较无干预组（A组）和有干预组（B组）之间的相关性。我们在A组和B组中分别观察到，尿道口平均长度为1.07 cm对0.75 cm（P<0.001），尿道口平均宽度为0.59 cm对0.38 cm（P<0.001）。考虑到尿道口的形态，我们提出了一种新的分类法，分为以下几组：（a）典型型；（b）裂隙型；（c）点状型；（d）马蹄型；（e）巨大尿道口型。点状尿道口是最需要干预的类型，其次是裂隙型和典型型尿道口（P<0.001）。点状和裂隙状尿道口，以及尿道口长度和宽度减小，是决定性因素。
