Of 402 penile prosthesis implanted at our institution between 1980 and 1987, 20 required explantation due to infection, erosion, pain or tissue necrosis. Of these 20 patients 14 were available for a prospective trial using a negative pressure device in an attempt to restore potency. Among these 14 patients 11 used the device at home for a minimum of 30 days after an acceptable office demonstration. Three patients did not desire the negative pressure device after an office visit test. Of the 11 home users 10 (91 per cent) reported at least satisfactory erections and successful intercourse. Interestingly, 5 of 6 patients in whom explantation was due to infection were able to use the negative pressure device successfully. Over-all, 10 of the 14 explant patients (71 per cent) engaged in regular successful intercourse using the device. The negative-pressure device can be a useful therapy for erectile impotence even in the sometimes challenging explant population. Despite previous corporeal infection and presumed fibrosis, negative pressure devices can provide patients with a functional erection-like state.
1980年至1987年间，在我们机构植入的402个阴茎假体中，有20个因感染、侵蚀、疼痛或组织坏死而需要取出。在这20名患者中，有14名患者可参与一项前瞻性试验，使用负压装置试图恢复性功能。在这14名患者中，11名患者在办公室演示合格后在家中使用该装置至少30天。3名患者在办公室试用后不想要负压装置。在11名在家使用该装置的患者中，10名（91%）报告至少有满意的勃起和成功的性交。有趣的是，6名因感染而取出假体的患者中有5名能够成功使用负压装置。总体而言，14名取出假体的患者中有10名（71%）使用该装置进行了规律的成功性交。即使在有时具有挑战性的取出假体的人群中，负压装置也可以成为治疗勃起功能障碍的有效疗法。尽管先前存在海绵体感染和假定的纤维化，但负压装置仍可为患者提供类似功能性勃起的状态。
