Background:
Robotic-assisted partial nephrectomy (RAPN) has emerged as a promising alternative to classical partial nephrectomy (CPN).
Aim:
This study aimed to compare the outcomes of RAPN and CPN for treating localized renal tumors through a meta-analysis of available literature.
Methods:
Chinese databases, such as CNKI, Chinese Science and Technology Periodicals Database (VIP), and Wanfang Full-text Database, were searched using Chinese search terms, and all published articles on PubMed and Web of Science were searched using English search terms. Articles on Localized Renal Tumors were included. RevMan5.3 software was used for meta-analysis. The funnel plots were drawn using Stata software to assess publication bias.
Outcomes:
This study aimed to identify the differences between robotic-assisted partial nephrectomy and classic partial nephrectomy in patients with localized renal tumors.
Results:
In total, 67 articles with 17 677 patients were included. The results demonstrate the advantages of RAPN over CPN for localized renal tumors. Compared to CPN and RAPN had significant differences in intraoperative blood loss, hospital stay duration, incidence of perioperative complications, and proportion of patients requiring blood transfusion. Regarding surgical outcomes, RAPN showed more favorable results regarding the incidence of positive resection margins, postoperative decline in glomerular filtration rate (GFR), postoperative local recurrence rate, and proportion of Trifecta achieved. However, there was no significant difference between RAPN and CPN regarding 5-year tumor-specific survival rates.
Clinical Implications:
The study suggests that robotic-assisted partial nephrectomy is a viable alternative to classic surgery for renal tumors.
Strengths And Limitations:
The strengths of this study are the use of a comprehensive search strategy and the inclusion of studies published in both English and Chinese. The limitations of this study are the small sample size and the need for long-term follow-up data.
Conclusion:
RAPN and CPN have similar overall survival outcomes for treating localized renal tumors. However, RAPN may offer advantages in terms of perioperative outcomes and preservation of renal function. Further studies are needed to confirm these findings and to identify the optimal surgical approach for individual patients.
