[A Case of Lymphorrhea after Radical Cystectomy Treated by Ultrasound-Guided Inguinal Intranodal Lymphangiography].

Abstract

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.
