Abstract

Radical nephroureterectomy (RNU) is the gold standard therapy for patients with upper urinary tract urothelial carcinoma (UTUC). In this study, we compared the effect of two surgical techniques, single-position complete retroperitoneoscopic radical nephroureterectomy (SCRNU) and laparoscopic nephroureterectomy with open bladder cuff excision (LNOBE), on perioperative and long-term oncological outcomes in UTUC patients. We retrospectively collected information on baseline characteristics, clinicopathological characteristics, surgical approaches, perioperative data, and survival outcomes from 174 patients who underwent RNU for UTUC between January 2018 and June 2023 in our center. The data were analyzed using the Mann-Whitney test, Fisher's exact test, Chi-square test. Linear regressions were applied to explore the effect of surgery approach on the continuous outcomes. Log-rank test and Kaplan-Meier survival curves were plotted to describe the survival outcome. Univariate and Multivariate Cox regressions were conducted to explore the independent prognostic factors. To address potential selection bias, we also employed an Inverse Probability of Treatment Weighting (IPTW) strategy. Patients who underwent SCRNU had shorter operative times (p < 0.001), reduced estimated blood loss (p < 0.001), less drainage on the first postoperative day (p = 0.009), shorter hospital stays (p = 0.001), and better intravesical recurrence-free survival than those who underwent LNOBE (IVRFS, HR: 0.17, 95% CI: 0.07-0.44, p = 0.007). Moreover, SCRNU was confirmed to be a protective factor for IVRFS after IPTW-adjusted Cox regression analysis was performed (HR: 0.17, 95% CI: 0.04-0.77, p = 0.021). SCRNU not only avoids intraoperative repositioning but also improves perioperative outcomes, including the reduction of operative time, blood loss, and length of hospital stay, and is associated with better IVRFS.

期刊介绍： We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
