Urinothorax (UT) is a rare and often undiagnosed condition, defined as the presence of urine in the pleural cavity due to the retroperitoneal leakage of urine accumulation, known as urinoma, into the pleural space. UT usually is a transudative pleural effusion that presents in patients with obstructive uropathy and it may occur following surgical procedures in the ureter or kidney such as ESWL, PCNL, and URS. Its diagnosis requires a high degree of clinical suspicion since the respiratory symptoms tend to be absent or mild and the urological signs tend to dominate. However, UT may rarely present with severe and acute dyspnea as well. The objectives of this study are to describe two new cases of this rare entity, a bilateral case and an ipsilateral case focusing on the side that occurs according to the affected renal insult, and to alert the physicians to include UT in their differential diagnosis of pleural effusions especially in patients with recent urinary tract disorders.
尿胸（UT）是一种罕见且常未被诊断出的病症，定义为由于尿液积聚（即尿瘤）从腹膜后渗漏至胸膜腔而导致胸膜腔内出现尿液。UT通常是一种漏出性胸腔积液，见于梗阻性尿路病患者，也可能发生在输尿管或肾脏的外科手术后，如体外冲击波碎石术（ESWL）、经皮肾镜取石术（PCNL）和输尿管镜检查（URS）。由于呼吸症状往往不存在或较轻，而泌尿系统体征往往较为突出，其诊断需要高度的临床怀疑。然而，UT也可能很少表现为严重的急性呼吸困难。本研究的目的是描述这种罕见病症的两例新病例，一例双侧病例和一例同侧病例，重点关注根据受影响的肾脏损伤情况而发生病变的一侧，并提醒医生在胸腔积液的鉴别诊断中纳入UT，尤其是近期有尿路疾病的患者。
