Abstract
Background
Radical nephroureterectomy is considered as the gold standard for the surgical treatment of upper urinary tract urothelial carcinoma (UTUC). Laparoscopic radical nephroureterectomy (LNU) can be performed via the transperitoneal (TLNU) or retroperitoneal (RLNU) approach, and each one has its own advantages and limitations. Our study was conducted to describe the difference between TLNU and RLNU by comparing the perioperative outcomes.
Methods
From January 2009 to October 2014, 68 patients underwent TLNU or RLNU at our center were retrospectively collected and 1:1 matched for age, body mass index and tumor side. Baseline characteristics and perioperative outcomes were evaluated and compared, respectively.
Results
There were no significant differences between the TLNU and RLNU group in terms of baseline characteristics, operating time, estimated blood loss, visual analogue pain scale, cosmetic results, intraoperative and postoperative complication rate. Compared to TLNU approach, RLNU was associated with a quicker time to first oral intake (2.9 vs 2.0 days, p = 0.02) and hospital discharge (6.7 vs 5.6 days, p = 0.02).
Conclusion
Both transperitoneal and retroperitoneal laparoscopic approaches are safe and effective methods for treatment of UTUC. Retroperitoneal approach has the advantage in terms of quicker bowel recovery and shorter hospital discharge.
