一名76岁女性被诊断为浸润性膀胱癌，接受了膀胱切除术、双侧髂外、髂内及闭孔淋巴结清扫术以及双侧输尿管皮肤造口术。病理检查未见淋巴结转移；然而，患者从术后第14天开始出现下腹疼痛和发烧，计算机断层扫描（CT）显示骨盆内有液体潴留。逆行肾盂造影显示尿路无渗漏，经皮穿刺盆腔后放置引流管。有大量引流液，其性质和成分提示淋巴漏。超声引导的结内淋巴管造影显示造影剂从双侧淋巴结清扫部位渗漏。淋巴管造影后，引流管的引流量减少。尽管引流很少但持续，但仍进行了硬化疗法，拔除引流管，患者出院。出院后，尿道拔除处有渗漏，CT显示复发性淋巴漏。患者再次入院，并进行了第二次淋巴管造影。尿道拔除部位渗漏逐渐减少，患者于术后第59天出院。出院后CT证实淋巴漏已缩小，此后未再复发。淋巴管造影是盆腔手术后淋巴漏的一种有前途的治疗选择。

A 76-year-old woman was diagnosed with invasive bladder cancer and underwent cystectomy, bilateral external iliac, internal iliac and obturator lymph node dissection, and bilateral cutaneous ureterostomy. Pathological findings showed no lymph node metastasis ; however, the patient had lower abdominal pain and fever from the 14th postoperative day, and computed tomography (CT) revealed fluid retention in the pelvis. Retrograde pyelography showed no leakage from the urinary tract, and a drain was placed after percutaneous puncture of the pelvic cavity. There was copious drainage fluid and its nature and composition suggested lymphorrhea. Ultrasound-guided intranodal lymphangiography revealed contrast material leakage from the bilateral lymph node dissection sites. After lymphangiography, drainage from the drain decreased. Despite the drainage being minimal yet persistent, sclerotherapy was performed, the drain was removed and the patient was discharged. After discharge, there was leakage from the site of urethral extraction, and CT revealed recurrent lymph leakage. The patient was readmitted, and a second lymphangiography was performed. The leakage from the site of urethral extraction gradually decreased, and the patient was discharged on the 59th postoperative day. CT after discharge confirmed that the lymphorrhea had shrunk in size, and there has been no recurrence since then. Lymphangiography is a promising treatment option for lymphorrhea after pelvic surgery.
