阴茎异常勃起14例临床分析

Clinical analysis of priapism(Report of 14 cases)

目的：探讨阴茎异常勃起的诊断、治疗及预后。方法：回顾性分析阴茎异常勃起患者14例的临床资料。其中血管活性药物所致8例，白血病所致2例，会阴外伤所致1例，原因不明3例。给予海绵体血气分析、阴茎彩色多普勒超声等检查，作海绵体穿刺减压及分流手术等治疗。结果：13例为低流量型异常勃起。1例为高流量型异常勃起，治疗后异常勃起均缓解。随访3～46个月，4例发生不同程度的海绵体纤维化或勃起功能障碍。结论：海绵体血气分析和彩色多普勒超声等检查有助于阴茎异常勃起准确及时的诊断。对于低流量型异常勃起，早期及时正确的治疗是避免术后海绵体纤维化、勃起功能障碍发生的关键。

Objective：To explore the diagnosis,treatment and prognosis of priapism. Methods.Fourteen patients with priapism were evaluated by cavernous blood gas analysis, color duplex ultrasonography, 8 cases of priapism resulted from intracavernosal injection of vasoactive agents, 2 from leukaemia, 1 from perineal trauma and 3 from unknown cause. Results：Among them,13 were of low flow and 1 was of high flow. After treatment, all patients were cured. During 3 to 46 months follow-up, 4 cases had developed cavernous fibrosis of penis or erection dysfunction. Conclusions：Cavernous blood gas analysis and color duplex ultrasonography are helpful in diagnosing priapism accurately and timely. Proper and early treatment is essential to avoid cavernous fibrosis and erection dysfunction.
