Complete Transperitoneal Laparoscopic Nephroureterectomy in a Single Position with Upper Urinary Tract Urothelial Carcinoma and Comparative Outcomes

Abstract Background: To describe techniques for complete transperitoneal laparoscopic nephroureterectomy for upper urinary tract urothelial carcinoma (UTUC) with a single position and here to report our outcomes. Materials and methods: Between January 2016 and June 2019, our group performed 50 complete transperitoneal laparoscopic nephroureterectomy (CTLNU) and 48 laparoscopic nephroureterectomy with open bladder cuff excision (LNOBE) for UTUC without metastases in our group. The clinical data were collected and analyzed retrospectively. Results: All 98 patients of radical nephroureterectomy performance were successfully without transferred into open surgery. No significant difference was found in patient’s clinical characteristics. Compare with LNOBE group, the CTLNU group had shorter operative time(98.5±40.3min vs 132.4±60.2min), less blood loss(60.4±20.3ml vs 150.6±50.2ml), shorter length of hospital stay(5.3±2.2d vs 8.1±2.3d), and shorter length of incision(6.3±1.2cm vs 11.5±3.2cm). Pathological stage, tumor grade, recurrence rate was similar between these two groups. Conclusions: Complete transperitoneal laparoscopic nephroureterectomy(CTLNU) in a single position had advantages of shorter operation time, less blood loss, and shorter incision length. This operative method could minimize invasive and accelerate recovery of patients which deserved clinical application and promotion.
