We investigated the incidence and clinical features of priapism in Japan, using a national administrative claims database, the Diagnosis Procedure Combination database. Priapism patients were identified using the International Classification of Diseases and Related Health Problems, 10th Revision code, N483 (priapism). Verified patient characteristics included age, comorbidities and management of priapism. Among 6.93 million inpatients, 46 patients with priapism were identified. Four had two admissions each for repeated events. The median age was 41.5 years (range, 11-89 years). A total of 21 patients had comorbidities; 3 had haematological malignancies, 4 had haemodialysis, 1 had a renal transplant, 2 had neurological problems, 4 had non-haematological malignancies, 3 had trauma and 6 had psychoses (2 cases had two comorbidities). All patients with non-haematological malignancies were over the age of 70 years, indicating that close attention is required to search for associated malignancies in elderly patients. The medical treatments included 6 vascular embolizations, 11 Winter method surgeries and 18 other operations. The incidence was estimated to be 0.13 (95% confidence interval, 0.097-0.17) per 100,000 person-years. This incidence was lower than that reported in other parts of the world.
我们使用国家行政索赔数据库（诊断程序组合数据库）调查了日本的阴茎异常勃起发病率和临床特征。使用国际疾病分类和相关健康问题第 10 版代码 N483（阴茎异常勃起）识别阴茎异常勃起患者。确认的患者特征包括年龄、合并症和阴茎异常勃起的治疗。在 693 万住院患者中，确定了 46 例阴茎异常勃起患者。4 例患者因重复事件各有两次住院。中位年龄为 41.5 岁（范围 11-89 岁）。共有 21 例患者合并症；3 例患有血液系统恶性肿瘤，4 例患有血液透析，1 例患有肾移植，2 例患有神经问题，4 例患有非血液系统恶性肿瘤，3 例患有创伤，6 例患有精神病（2 例合并两种疾病）。所有患有非血液系统恶性肿瘤的患者年龄均超过 70 岁，这表明需要密切关注老年患者是否存在相关恶性肿瘤。治疗方法包括 6 例血管栓塞术、11 例 Winter 方法手术和 18 例其他手术。发病率估计为每 100,000 人年 0.13（95%置信区间 0.097-0.17）。这一发病率低于世界其他地区报告的发病率。
