OBJECTIVE: To describe a novel technique allowing laparoscopic nephroureterectomy with bladder cuff excision and lymphadenectomy, in a complete supine position, without patient repositioning.
METHODS: Between January 2016 and October 2018, 20 consecutive patients with upper urinary tract urothelial carcinoma underwent supine extraperitoneal laparoscopic nephroureterectomy. The patients were placed in the complete supine position. A 4-cm pararectal skin incision was made and the extraperitoneal space was developed. We used a unique port placement that permits complete access for nephroureterectomy, bladder cuff excision and concomitant lymphadenectomy. Operative parameters and pathological data were analyzed.
RESULTS: The median age was 70 years (range 49-88 years), the mean operative time was 234 min (range 175-293 min) and the mean estimated blood loss was 67 mL (range 50-200 mL). There were no intraoperative complications, and no patients required transfusion or open conversion. The median number of removed lymph nodes was 10; only one patient had node metastasis. The total operative time and time for nephroureterectomy were significantly longer in the first 10 patients (first group) than in the second 10 patients (second group). Times required for bladder cuff excision and lymphadenectomy did not differ between the two groups.
CONCLUSIONS: Our novel technique, which enables completion of the entire procedure of nephrouretectomy with bladder cuff excision and lymphadenectomy in the supine position without patient repositioning, is safe and minimizes operative time while maintaining oncological efficacy. We believe this approach might become a standard option for patients with upper urinary tract urothelial carcinoma.
