Abstract
Background:
Several studies have reported on the safety and feasibility of percutaneous nephrolithotomy (PCNL) under local anesthesia (LA). The aim of this systematic review is to assess the perioperative outcomes of PCNL under LA.
Methods:
Three electronic databases, including MEDLINE, EMBASE, and Web of Science, were searched for relevant English-language studies published from January 1980 to March 2023. The systematic review has been performed according to the Cochrane style and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. The primary outcomes include stone-free rate (SFR) and conversion to general anesthesia (GA). Secondary outcomes include postoperative complications.
Results:
Of 301 articles that were extracted, 42 full-text articles were selected, of which 36 were excluded, yielding a total of 6 articles in our results. A total of 3646 patients were included in this review. The SFR of PCNL under LA ranged between 69.9% and 93.3%. PCNL under LA was not tolerated by 19 (0.5%) patients: 6 patients had conversion to general anesthesia, 2 had conversion to epidural anesthesia, and 11 had their procedure terminated. The overall complication rates varied from 4.8% to 21% across studies. Grade I–II complications were reported in 2.4%–16.7% of cases, while grade III–IV complications were encountered in 0.5%–5% of patients.
Conclusions:
In this review, we found a few studies that examined the outcomes of PCNL under LA, which highlight the feasibility and safety of PCNL under LA and the low conversion rate to GA.
