We analyzed our experience with the Dynaflex* self-contained inflatable penile prosthesis to define specific complication rates and patient satisfaction in the long term.
From October 1990 through October 1994, 62 men underwent implantation of a Dynaflex prosthesis. Mean and median time since implantation was 50 and 53 months, respectively (minimum 24). In addition to standard followup and tabulation of complications, patients were contacted and interviewed regarding satisfaction with the prosthesis.
Mechanical device failures occurred in 9.7% of cases with a mean time to failure of 40 months in 6 prostheses. An additional 16.1% of patients had an unsuccessful outcome due to dissatisfaction with the Dynaflex. Of the patients with a functional Dynaflex prosthesis contacted at the time of this review 88.1% expressed satisfaction.
Mechanical failure rates for the Dynaflex prosthesis are comparable to those previously reported for multicomponent inflatable penile prostheses. Patient dissatisfaction, mainly due to difficulty in operating the Dynaflex inflation and deflation mechanisms, is much higher than for multicomponent inflatable penile prostheses. However, in patients who are successful in mastering operation of the Dynaflex satisfaction rates are high. Careful patient selection, and extended training and education efforts are the keys to maximizing successful outcomes with the Dynaflex prosthesis.
我们分析了使用Dynaflex*自含式可膨胀阴茎假体的经验，以确定长期的特定并发症发生率和患者满意度。
从1990年10月至1994年10月，62名男性接受了Dynaflex假体植入。植入后的平均时间和中位时间分别为50个月和53个月（最短24个月）。除了对并发症进行标准随访和列表统计外，还联系并询问了患者对假体的满意度。
9.7%的病例发生机械装置故障，6个假体的平均故障时间为40个月。另外16.1%的患者因对Dynaflex不满意而手术结果不佳。在本次评估时联系到的使用功能性Dynaflex假体的患者中，88.1%表示满意。
Dynaflex假体的机械故障率与先前报道的多部件可膨胀阴茎假体相当。患者不满主要是由于Dynaflex充气和放气机制操作困难，远高于多部件可膨胀阴茎假体。然而，对于成功掌握Dynaflex操作的患者，满意度较高。仔细选择患者，以及加强培训和教育工作是使Dynaflex假体获得最大成功结果的关键。
