1 · What the graph read from it

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.

2 · The registry

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

objectivesTo evaluate the safety and efficacy of total tubeless percutaneous nephrolithotomy (PCNL) without retrograde insertion of a ureteral catheter for the treatment of kidney stone patients without hydronephrosis.

methodsThis prospective randomized controlled study at a tertiary care medical center was conducted from August 2019 to April 2023. Kidney stone patients diagnosed by computed tomography (CT) without significant hydronephrosis were randomly assigned to two groups: total tubeless PCNL without retrograde insertion of a ureteral catheter (group 1) and traditional PCNL (group 2). The primary endpoint was postoperative complications, while the secondary endpoints included the stone-free rate (SFR), operative time, length of postoperative hospital stay, and medical costs.

resultsA total of 99 patients were recruited, including 50 patients in group 1 and 49 patients in group 2. There were no significant differences in postoperative complications and SFR between the two groups (P > 0.05). However, relative to group 2, patients in group 1 had significantly shorter operative time (58.5 ± 25.39 min vs. 82.98 ± 26.02 min, P < 0.001) and length of postoperative hospital stay (1.98 ± 1.72 days vs. 4.39 ± 2.95 days, P < 0.001), as well as significantly lower medical costs (3190.30 ± 590.58 dollars vs. 3552.78 ± 967.79 dollars, P = 0.03).

conclusionTotal tubeless PCNL without retrograde insertion of a ureteral catheter for the treatment of kidney stone patients without hydronephrosis is safe and effective for urologists with extensive experience in PCNL.
