【摘要】 目的:研究按摩盆腔器官改变阴茎血液供应状态,以及按摩盆腔的不同器官对阴茎血流的影响不同。方法:用彩色超声多普勒分别在3个时相,即平静状态、直肠按摩时相和前列腺按摩时相,观测10名健康自愿者右侧阴茎海绵体动脉血流参数:收缩期血流速度峰值(peaksystolicvelocity,PSV),舒张末期血流速度(enddiastolicvelocity,EDV)和阻力指数。结果:10名健康自愿者在直肠和前列腺按摩前的阴茎海绵体动脉PSV,EDV和阻力指数分别为(8.86±3.19)cm/s,(1.13±0.49)cm/s和0.87±0.06,按摩直肠壁时分别为(9.21±3.65)cm/s,(1.69±0.64)cm/s和0.78±0.14,按摩前列腺时为(18.96±6.47)cm/s,(2.60±1.22)cm/s和0.86±0.05。按摩直肠壁时EDV增加(t=2.32,P=0.046),PSV无明显变化(t=0.29,P=0.78);按摩前列腺时PSV和EDV增加(t值分别为3.89和3.92,P值均为0.004)。10名自愿者中,有7名在前列腺按摩时出现阴茎膨胀,但无一名勃起。结论:按摩直肠壁可明显引起阴茎海绵体动脉EDV增加,而按摩刺激前列腺组织可明显引起阴茎海绵体动脉PSV和EDV增加,说明刺激盆腔的不同器官对阴茎血流影响截然不同。刺激盆腔脏器时的阴茎血流变化可能是通过神经反射弧完成的。更多还原

【Abstract】 AIM:To study the massage to pelvic organs altering the status of penile blood flow and the different effects on penile blood flow by massaging different organs of pelvic kidney. METHDS:The peak systolic velocity(PSV), end diastolic velocity(EDV) and resistant index(RI) of right lateral cavernosal arteries were evaluated and obtained in 10 healthy volunteers with color doppler ultrasonography respectively at three distinct phases:sedentary condition,rectal massage and prostate massage. RESULTS:The PSV,EDV and RI of right cavernosal arteries in 10 health subjects were(8.86±3.19)cm/s,(1.13±0.49)cm/s and 0.87±0.06 scanned before massaging rectal walls and prostate glands,(9.21±3.65) cm/s,(1.69±0.64)cm/s and 0.78±0.14 at the phase of massaging rectal walls and(18.96±6.47)cm/s,(2.60±1.22)cm/s and 0.86±0.05 at the phase of massaging prostate.The increase of EDV during massaging to rectal walls showed statistical significance(t=2.32,P=0.046),whereas, rectal massage did not alter PSV significantly(t =0.29, P=0.78).Both PSV and EDV increased markedly at massage to prostate phase and showed statistical significance(t=3.89 and 3.92,Both P=0.004).Seven out of 10 subjects presented penile tumescence during prostate massages but no full penile erection was observed. CONCLUSION:The obviously increase of EDV of cavernosal arteries was scanned during massages on rectal walls.The massages to prostates can obviously cause the increase of both PSV and EDV.It was found that the effects on penile blood flow varied with the stimulation to distinct pelvic organs.It is postulated that a certain nerve reflex may be involved in the phenomena observed in the present study.更多还原
