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

purposeTo determine whether omitting routine indwelling catheterization after ureteroscopic lithotripsy reduces postoperative lower urinary tract symptoms and enhances patient comfort, without compromising safety.

methodsIn this prospective, multicenter, randomized controlled trial, 180 patients undergoing ureteroscopic lithotripsy from August 2024 to June 2025 at four centers were allocated to either the No-Catheter group (n = 91) or the Catheter group (n = 89). The primary outcome was the incidence of lower urinary tract symptoms (LUTS) evaluated by the Patient Perception of Intensity of Urgency Scale and the Visual Analog Scale for pain at 1 h, 4 h, 1 day postoperatively. Secondary outcomes included complications (fever and urinary retention) and distressing memories assessed at a 1-month follow-up using the Subjective Units of Distress Scale.

resultsThe No-Catheter group had significantly lower LUTS incidence at day 1 (9.9% vs. 24.7%, p = 0.012) and reduced urgency at 1 h and 4 h (p < 0.05). Fewer No-Catheter patients reported distressing LUTS memories at 1 month (7.7% vs. 25.8%, p < 0.001). Complication rates were comparable between groups (p > 0.05).

conclusionOmitting routine indwelling catheterization after ureteroscopic lithotripsy appears to be a safe strategy that significantly reduces postoperative lower urinary tract symptoms and improves the patient experience. These findings support a change in clinical practice away from routine catheterization.
