Spongiosography can help visualize the same venous system seen in cavernosography during erection with papaverine. In 4 cases where the deep dorsal vein was ligated, spongiosography was used to demonstrate why improvement was not sustained. These ligations were not successful because the deep dorsal vein can rechannel through small veins at the site of excision. Furthermore, the external pudendal vein may divert the blood into the femoral vein after dorsal vein ligation. The distribution of the circumflex veins at the level of the spongiosal bodies represents a formidable anastomotic network of veins that bypass all attempts to restrict deep dorsal vein outflow.
海绵体造影术有助于观察到在使用罂粟碱勃起时海绵体造影术中所见的相同静脉系统。在4例结扎阴茎背深静脉的病例中，使用海绵体造影术来证明改善效果未能持续的原因。这些结扎未成功，因为阴茎背深静脉可通过切除部位的小静脉重新形成通道。此外，阴茎背静脉结扎后，阴部外静脉可能将血液引流至股静脉。海绵体层面的旋静脉分布代表了一个强大的静脉吻合网络，绕过了所有限制阴茎背深静脉流出的尝试。
