To study the drainage proportions from the corpora cavernosa in defrosted human cadavers, as the veins related to penile erection were recently depicted to comprise the deep dorsal vein (DDV), a pair of cavernous veins (CVs) and two pairs of para-arterial veins (PAVs), as opposed to a single DDV between Buck's fascia and the tunica albuginea of the human penis.
With no formalin fixation, 10 defrosted male human cadavers were used for this study. After injecting a 10% solution of colloid, and with the intracavernous pressure (ICP) fixed at 90 mmHg, the perfusion rate was recorded before and after the DDV, CVs and PAVs were removed, respectively. Finally, measurements were again recorded after penile arterial ligation. Cavernosography was used if required.
The mean (range) perfusion rate for maintaining the ICP at 90 mmHg was 30.2 (15.5-90.8) mL/min, whereas the arterial perfusion rate was 2.8 (0.3-3.9) mL/min. The mean (range) drainage proportion of the corpora cavernosa was 60.5 (50.3-69.7)%, 11.9 (5.8-22.9)% and 11.4 (5.2-15.0)% via the DDV, CVs and PAVs, respectively. The remaining drainage proportion was 15.6 (14.1-18.1)%. This study shows the separate drainage contributions of the DDV, CVs and PAVs to the corpora cavernosa of the human penis.
We conclude that the venous drainage system of the corpora cavernosa is much more complex than the previous depictions of it, and the consequent focus on a single DDV. This also shows the independent role of each venous system.
研究解冻后人体尸体阴茎海绵体的引流比例，因为最近发现与阴茎勃起相关的静脉包括一条阴茎背深静脉（DDV）、一对海绵体静脉（CVs）和两对动脉旁静脉（PAVs），这与人类阴茎白膜和巴克筋膜之间只有一条阴茎背深静脉的传统观点不同。
本研究使用10具未经福尔马林固定的解冻男性尸体。注入10%的胶体溶液后，将海绵体内压（ICP）固定在90mmHg，分别记录在切除DDV、CVs和PAVs之前和之后的灌注速率。最后，在阴茎动脉结扎后再次记录测量值。必要时采用海绵体造影。
将ICP维持在90mmHg时的平均（范围）灌注速率为30.2（15.5 - 90.8）mL/min，而动脉灌注速率为2.8（0.3 - 3.9）mL/min。阴茎海绵体通过DDV、CVs和PAVs的平均（范围）引流比例分别为60.5（50.3 - 69.7）%、11.9（5.8 - 22.9）%和11.4（5.2 - 15.0）%。其余引流比例为15.6（14.1 - 18.1）%。本研究显示了DDV、CVs和PAVs对人类阴茎海绵体的单独引流作用。
我们得出结论，阴茎海绵体的静脉引流系统比之前所描述的要复杂得多，之前过于关注单一的DDV。这也显示了每个静脉系统的独立作用。
