Occurrence of priapism after transient right MCAO in Swiss albino mice

Introduction: There are few reports about sexual problems in animal models after stroke. The aim of this paper is to report the occurrence of priapism after right MCAO in Swiss albino mice. In addition, we compared neurological score and apoptosis between the priapism-affected and unaffected mice.

Methods: Swiss albino mice were subjected to 45?min’ MCAO and 7?days’ reperfusion. Mice were observed before MCAO, then daily for 7?days to assess priapism. Neurological status and apoptosis (TUNEL assay) were assessed and compared in priapism and non-priapism mice.

Results: The results showed that the incidence of priapism after MCAO in Swiss albino mice were 65%. Priapism was detectable often at day 2 after stroke. Priapism-affected group had more severe behavioural deficits after stroke compared to non-priapism stroke mice.

Conclusion: Priapism after right MCAO is not rare in albino mice and could be considered as a marker of stroke severity. Further studies are needed to assess the incidence of priapism after stroke in other animal species used for stroke studies such as rat.     

缺血性阴茎异常勃起的诊断及阶梯治疗

阴茎异常勃起是泌尿男科一种罕见的疾病,需要急诊干预治疗。临床常分为缺血性,非缺血性二种类型,其中缺血性阴茎异常勃起占绝大多数。缺血性阴茎异常勃起会导致海绵体组织纤维化和勃起功能障碍,随着缺血时间的延长,海绵体会永久损伤。不同的阴茎持续勃起时间,不同的治疗方式影响患者的预后,会造成不同程度的勃起功能障碍。遂此病需尽早明确所属类型。通过询问患者病史,细致查体,结合实验室检查中阴茎海绵体血气分析及彩色多普勒检查,明确患者状态。并采取冷敷、镇静,海绵体抽吸灌注或海绵体注射拟交感类药物,外科分流手术等阶梯治疗的方式,最大限度保护患者勃起功能。本文对缺血性阴茎异常勃起的诊断及阶梯治疗进行综述。     

低血流量阴茎异常勃起的诊断及治疗(附35例报告)

目的:探讨低血流量阴茎异常勃起的诊断和治疗方法。方法:选取2010年9月至2016年10月我院收治的低血流量阴茎异常勃起住院患者35例,综合阴茎海绵体血气分析及彩色超声检查35例均为低血流量(缺血性)阴茎异常勃起,勃起时间12至240小时,平均72小时。其中,有31例患者应用过药物藻酸双酯钠,1例患者为性生活后导致异常勃起,1例患者为排尿后导致异常勃起,2例患者应用何种药物不详。结果:入院后给予冷敷、镇静、阴茎海绵体灌洗等治疗后5例症状消失,其余30例患者阴茎仍持续勃起。遂施行阴茎海绵体尿道海绵体分流术,术后全部病人阴茎萎软。随访6至24个月,31例患者出现勃起功能障碍,其中轻度患者7例,中度患者16例,重度患者8例。结论:(1)阴茎海绵体血气分析、彩色多谱勒超声检查是诊断阴茎异常勃起的重要方法。(2)冷敷、镇静、阴茎海绵体抽吸减压等治疗是低流量阴茎异常勃起的首选,如无效应及时行阴茎海绵体尿道海绵体分流术。
