A 38-year-old female developing pelvic lymph node recurrence (cN2) of bladder cancer was referred to our hospital. Eighteen months earlier, she had received complete transurethral resection of bladder tumor and pathological diagnosis of muscle-invasive urothelial carcinoma with micropapillary variant had been made. She had declined radical cystectomy or chemoradiation because of a strong desire to spare the bladder and fertility. She received induction gemcitabine/cisplatin therapy. After three
cycles, she achieved a clinically complete response. Then, she underwent transumbilical gasless retroperitoneoscopic super-extended pelvic lymph node dissection up to the inferior mesenteric artery trunk using the three-dimensional head-mounted display system. Pathologically, one of 42 resected lymph nodes was positive for metastasis. She is alive with no evidence of disease 5 years after lymph node dissection, retaining functional bladder and normal ovarian functions.
