Background:
To describe the techniques and outcomes of complete transperitoneal laparoscopic nephroureterectomy (CTLNU) for upper urinary tract urothelial carcinoma (UTUC) in a single position.
Materials And Methods:
Those patients with localized UTUC were included, among which 50 cases had CTLNU while 48 cases had laparoscopic nephroureterectomy with open bladder cuff excision (LNOBE). The clinical data were collected and analyzed retrospectively.
Results:
All 98 patients underwent successful procedures of radical nephroureterectomy without transferring into open surgery. No significant difference was found among baseline clinical characteristics. Compared with the LNOBE group, the CTLNU group had a shorter operative time (98.5±40.3 min vs. 132.4±60.2 min), less blood loss (60.4±20.3 ml vs. 150.6±50.2 ml), shorter length of hospital stay (5.3±2.2 days vs. 8.1±2.3 days), and shorter incision (6.3±1.2 cm vs. 11.5±3.2 cm). The disease-related outcomes such as pathological stage, tumor grade, and recurrence rate were similar between the two groups.
Conclusions:
The CTLNU in a single position had advantages of shorter operation time, less blood loss, and shorter incision length. This surgical technique is a more minimally invasive, simplified, and effective way to perform the radical nephroureterectomy.
