Percutaneous vs Laparoscopic Treatment for Simple Renal Cysts: A Meta-analysis

Objective: To compare the percutaneous and laparoscopic treatment for renal cyst to determine the optimal therapy for patients with renal cyst. Materials and Methods: A systematic search of PubMed, Cochrane Library, Web of Science, and EMBASE databases was conducted for articles published through June 3, 2020, using the preferred reporting items for systematic reviews and meta-analyses guidelines. Results: We found 493 studies from databases, and 6 were considered for the evidence synthesis. A total of 1631 cases were included. Of these patients, 488 cases underwent laparoscopic treatment and 1143 cases underwent percutaneous treatment. Symptomatic and radiologic success were higher for laparoscopic treatment (odds ratio [OR], OR=3.59, confidence interval [95% CI], 1.45-8.88, p=0.006; and OR=7.46, 95% CI 3.99-13.94, p<0.00001, respectively). Minor or severe complications were similar between the two treatments (OR=1.54, 95% CI 0.40-5.98, p=0.53; OR=3.13, 95% CI 0.03-359.76, p=0.64, respectively). Conclusion: Laparoscopic treatment for renal cyst was associated with better symptomatic and radiologic success, and its complication was no more than percutaneous treatment.
