Flexible ureteroscopic incision and drainage or laparoscopic unroofing for the parapelvic renal cysts: A systematic review and meta-analysis.

The aim of the present study was to compare flexible ureteroscopy and laparoscopy in the treatment of peripelvic renal cysts, so as to determine the best treatment method for patients with peripelvic renal cysts. A systematic search of the PubMed, EMBASE, Cochrane Library, CONAHL, Clinicaltrials.gov, Google Scholar, CNKI and WanFang DATA databases was conducted for articles published over 22 years (December 1980-December 2022) using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. By searching the database, a total of 594 studies were found, of which eight were analyzed as evidence. A total of 394 patients were included in the present study. Of these, 193 were treated laparoscopically and 201 were treated by flexible ureteroscopy. In terms of analysis results, radiation reexamination after laparoscopic therapy had a higher success rate. Ureteroscopy has advantages in the time spent in the operation, the amount of blood lost during the operation, the time to recover the anal exhaust after the operation and the length of postoperative hospital stay. There were no significant difference in postoperative recurrence or complications between the two surgical methods. After comprehensive analysis, it was considered that flexible ureteroscopy has more advantages in the treatment of peripelvic renal cyst, which is mainly manifested in the duration of operation, the total amount of blood loss during operation, the interval of recovery of anal exhaust after operation and the total length of postoperative hospital stay. It is worth further exploration and promotion. [ABSTRACT FROM AUTHOR]
