Application of inguinal incision in retroperitoneal laparoscopic nephroureterectomy in the treatment of upper urinary urothelial carcinoma / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the application of inguinal incision in retroperitoneal laparoscopic nephroureterectomy(LNU)in the treatment of upper urinary urothelial carcinoma(UUUC).Methods From Mar.2007 to Jan.2012,186 retroperitoneal LNU procedures on 115 males and 71 females for the treatment of UUUC were performed in our institute.All cases were grouped as inguinal incision group(n =112)and lumbar incision group(n =74)according to specimen retrieval incision.Operative time,estimated blood loss,postoperative analgesia,hospital stay,incision complications,cosmetic satisfaction and tumor recurrence were compared between the 2 groups.Results All the 186 cases of operation were successfully accomplished.There were no differences in tumor stage,tumor grade,mean operative time,blood loss between the 2 groups.In inguinal incision group,the incidence of incision fat liquefaction,incision hernia,incision bulging,lumboabdominal unsymmetry and postoperative analgesia was less than that of lumbar incision group.In inguinal incision group,the mean hospital stay was shorter,cosmetic satisfaction(Ⅰ/Ⅱ/Ⅲ)was better(7/24/81 versus 22/18/34,P ＜ 0.01).Recurrence rate of UUUC in middle and inferior segment of ureter was fewer than that of lumbar incision group(5.3％ versus 35.0％,P ＜0.01).Conclusion Retroperitoneal LNU for UUUC combined with inguinal incision offers advantage of less trauma,less complications,higher cosmetic satisfaction and lower tumor recurrence.
