成人阴茎的三维数字化图像分析

目的对成人阴茎进行三维数字化图像分析,为阴茎整形修复获得手术前后形变参数及手术方案的选择,提供精确的形态学数据。方法采用Angel数字快速测量诊断系统,分别测量200例正常成人阴茎安静状态和勃起时的长度、周长、以及勃起时角度与阴茎长度、周径的关系。结果随着年龄和身高增长,阴茎也随之增长;身高与阴茎长度不成正比;阴茎勃起时随着角度的增加硬度增强,但勃起硬度变化时阴茎体积无明显变化。结论从不同径线不同角度对阴茎进行计算机三维测量分析,为阴茎整形修复术前设计、术后效果评价提供重要的量化指标。

No colocalization of immunoreactivities for VIP and neuronal NOS, and a differential relation to cGMP-immunoreactivity in bovine penile smooth muscle

The distribution of immunoreactivity (IR) for the neuropeptide vasoactive intestinal polypeptide (VIP) and neuronal nitric oxide synthase (nNOS) in the bovine retractor penis muscle (RP) and penile artery (PA) was studied by using two different methods. The distribution of these immunoreactivities was also compared with that of the immunoreactivity for cyclic guanosine monophosphate (cGMP). In both tissues the nerve fibers and terminals immunoreactive for VIP had a distribution that was completely different from that of the nerve fibers and terminals immunoreactive for nNOS. This contrasts with the previous observations in penile smooth muscle of other species. In the RP, as well as in the PA, many of the VIP-IR fibers were also immunoreactive for neurofilaments (NF), whereas the nNOS-IR fibers were consistently devoid of NF-IR. Stimulation with sodium nitroprusside, a nitric oxide donor, considerably increased cGMP-IR in the smooth muscle cells in both RP and PA, and in several nerve fibers in PA. Many of these cGMP-IR nerve fibers exhibited nNOS-IR, whereas none of them was immunoreactive for VIP. Our results suggest that the degree of coexistence of VIP-IR and nNOS-IR in the nerve fibers and terminals innervating penile smooth muscle show wide species differences. They also suggest that the mechanisms by which VIP could be involved in neurogenic penile erection may vary between species.     

Constricting band penile injury with urethral transection

Constricting band penile injuries in children may be caused by inadvertent entrapment by a variety of agents including hair, thread, and circumcision dressings. Alternatively, the offending band may have been self-applied or applied by an attendant. Unrelieved, the band causes serious vascular occlusion, progressive tissue necrosis, and injury to the urethra and erectile tissue. We report a case of CBPI in a 12-year-old circumcised boy. The glans was attached to the penile shaft by a tenuous segment of tissue dorsally with complete transection of the urethra. A three-stage reconstruction using a delayed groin flap was successful.     

82例阴茎鳞状细胞癌临床诊断与治疗

目的：提高阴茎鳞状细胞癌的诊断和治疗水平。方法：回顾性分析1980-2005年82例阴茎鳞状细胞癌患者临床资料,结合文献复习进行讨论。结果：77例病例行手术治疗,其中阴茎部分切除术64例,阴茎全切术13例。阴茎切除加髂腹股沟淋巴结清扫14例（腹股沟淋巴结均为阳性,髂淋巴结均为阴性）。放疗3例,化疗1例,放化疗联合治疗1例。71例患者随访1～10年,5例1年内死亡,17例2～5年内死亡,49例生存5年以上,占69％,其中34例生存10年,占48％,11例失访。结论：包茎、包皮过长是阴茎鳞状细胞癌的重要诱因;HPV感染可能与阴茎鳞状细胞癌发生有关。外科手术治疗是目前治疗阴茎鳞状细胞癌的有效方法;淋巴结清扫范围应采用由浅至深逐级切除的方式;放、化疗及联合治疗疗效尚不确切。     

阴茎海绵体破裂治疗并文献分析

目的:探讨阴茎海绵体破裂的治疗方法。方法:总结分析某医院收治的8例阴茎海绵体破裂患者的临床资料、诊断及治疗。结果:8例患者中,7例患者立即手术治疗,1例保守治疗。术后患者性生活正常,无阴茎勃起功能障碍。结论:阴茎海绵体破裂有典型的病史及临床表现,急诊手术治疗是推荐的治疗方法。     

Extraskeletal osteosarcoma of penis: A case report

Extraskeletal osteosarcoma (EOS) is rare and commonly arises in the retroperitoneum, limbs, head and neck. There is no significant difference between EOS and other malignant tumors in soft tissue. Localized pain and swelling are the common presenting symptoms. Clinical diagnosis of EOS is difficult, imaging techniques may be helpful and careful, and the histopathological analysis is necessary. The common histological variants of EOS include: osteoblastoma, chondroblastoma, and fibroblastoma, and other unusual subtypes were reported occasionally. It should be distinguished with myositis ossificans, malignant mesenchymoma, giant cell tumor and parosteal osteosarcoma. We present an EOS arising in the penis. The primary site and histological category of the tumor were extremely rare. We hope the case will be helpful to the recognition of clinical signs, iconography and histopathology of EOS.
