Determining the safety and effectiveness of percutaneous nephrolithotomy and retrograde intrarenal surgery in treating nephrolithiasis in patients with solitary kidneys.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We performed a meta-analysis to compare the safety and effectiveness of percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) in treating nephrolithiasis ≥ 2 cm in patients with solitary kidneys. This systematic review was registered on PROSPERO (registration ID: CRD42021270519). The search time was set from the establishment of the databases until April 30, 2021. A systematic search was performed in the PubMed, MEDLINE, Web of Science, Scopus, China National Knowledge Infrastructure (CNKI), Cochrane Library, and Embase databases. Stata 16 was used to perform the statistical analysis of the extracted data. After screening using strict inclusion and exclusion criteria, five studies with a total of 474 patients were included in the final meta-analysis. According to the literature quality assessment scale statistics, the five studies included were of high quality. The results of the meta-analysis showed that RIRS had lesser hemoglobin loss (HL), shorter length of hospital stay (LOS), lower initial (OR = 3.39, 95% CI [1.97, 5.83], P = 0.02) and final stone-free rates (OR = 2.24, 95% CI [1.24, 4.06], P = 0.03), but a higher incidence of grade III-IV complications (OR = 0.29, 95% CI [0.08, 0.97], P = 0.04) than PCNL. The difference between the two surgical methods was not statistically significant in terms of operation time (OT), grade I-II complication rate, and total complication rate. For nephrolithiasis ≥ 2 cm in patients with a solitary kidney, RIRS has the advantage of less HL and shorter LOS, while PCNL benefits from its higher SFR (both initial and final). Both RIRS and PCNL are effective treatments for nephrolithiasis in patients with a solitary kidney, and clinicians should choose the most appropriate option to achieve the best treatment outcome, taking into account the patient's underlying conditions and medical conditions.
