摘要

目的:观察大鼠未成熟睾丸单侧扭转后对健侧睾丸血流供应的影响

并比较不同处理方法的疗效。方法:建立3周龄大鼠左侧睾丸扭转（Testis torsion

TT）模型

随机分为对照组、扭转组、扭转复位组和切除组。彩色多普勒测量各组术前、术后8h（即扭转复位或切除术后2h）、12h、24h、72h及1周时右侧精索内睾丸动脉收缩期最大血流速度（Vs）

舒张末期血流速度（Vd）和阻力指数（RI）。结果:左侧睾丸扭转后

右侧睾丸的血供较对照组明显增加（P<0.01）

以术后8h为高峰;解除扭转6h后

右侧睾丸动脉Vs值较扭转复位2h时有明显下降（P<0.01）

但仍显著高于对照组和扭转组（P<0.01）;切除扭转睾丸6h后

右侧睾丸动脉Vs值较扭转切除2h时显著升高（P<0.01）

随后逐渐下降

术后72h右侧睾丸动脉Vs值显著高于对照组和复位组（P<0.01）

而低于扭转组（P<0.01）;术后1周

Vs、Vd、RI均为扭转切除组>扭转复位组>扭转组>对照组（P<0.01）。结论:大鼠未成熟睾丸单侧扭转后

扭转复位和扭转切除处理均可引起对侧睾丸血供显著持续增加。

Abstract

Objective:To observe hemodynamic effects of unilateral testicular torsion on the contralateral testis in immature rats

and compare the therapeutic effects of different treatments.Methods:The left testicular torsion model was established in rats of 3m old

and divided into normal control group

testicular torsion group

reposition group and orchectomy group.The value of peak systolic velocity(Vs)

value of end diastolic velocity(Vd)and resistive index(RI)of right testicular artery of pre-operation

8 h(2 h after reposition or orchectomy)

12 h

24 h

72 h and 1 w post-operation were measured by color Doppler in each group.Results:The blood supply of the right immature testes increased consistently after testicular torsion of the left side

and reached the peak value at 8h after the operation.The Vs of right testicular artery reduced significantly at 6 h compared with that at 2 h after reposition(P<0.01)

but still higher than that in control group or the testicular torsion group.The Vs of right testicular artery increasd significantly at 6 h compared with that at 2 h after orchectomy(P<0.01)

then decreased gradually

which was higher at 72 h after operation than that in control group or the reposition group

but lower than that in testicular torsion group.The Vs

Vd and RI were all higher in orchectomy group than those in reposition group at 1w after operation.Conclusion:The unilateral immature testicular torsion significantly induces increase of blood supply of contralateral testis in immature rats

and the increase is continuing in both the reposition group and orchectomy group.
