Transvaginal specimen extraction was applied in female patients to reduce incisional pain and improve cosmesis. Peri-operative complications were evaluated using the Clavien-Dindo classification system. Postoperative pain was evaluated during hospitalization using a numeric pain rating scale (scales of 1 to 10). Patients who underwent retroperitoneal laparoscopic surgery combined with open excision of the distal ureter during the same period were included as a control group (conventional RNU, consisting of laparoscopic nephrectomy combined\u00a0with open bladder cuff excision) for pain scale evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The novel surgery was successfully completed for all four patients (two males and two females). The mean pneumoperitoneum time for retroperitoneoscopic nephroureterectomy and specimen extraction was 174\u2009min, while the mean pneumovesicum time for the ureteral orifice excision was 88\u2009min. One male patient had bladder leakage at the suture site of the bladder wall, which lasted for 2 weeks. No patient experienced recurrent disease during the follow-up period (median, 10\u2009months). Mild to moderate pain lasted for 5 or 6\u2009days after RNU. A couple of days after surgery, the numeric pain rating scale of complete laparoscopic RNU and conventional RNU group reached its peak level at 3.0 \u00b1 1.8 and 5.3 \u00b1 2.8, respectively. There was no statistical difference in the degree of postoperative pain (\n                      <jats:italic>P<\/jats:italic>\n                      = 0.31).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We described our initial experience and outcome of complete laparoscopic RNU for UTUC.
