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

backgroundThe clinical benefit of preoperative ureteric double J (JJ) stenting prior to ureterorenoscopy (URS) for uncomplicated urolithiasis remains debated. In cases requiring urgent decompression or delayed definitive treatment, JJ stenting is frequently employed. However, prolonged indwelling time may increase the risk of bacterial colonization and subsequent infectious complications, though evidence remains limited.

methodsWe conducted a retrospective, single-center study including 350 adult patients who underwent URS at the Department of Urology, Lausanne University Hospital (CHUV) between January and December 2023. The primary outcome was infectious complication, defined as the occurrence of ≥ 1 of the following within 30 days postoperatively: fever > 38.0 °C, systemic inflammatory response, hospitalization > 3 days with documented signs of infection, or readmission for urinary infection. Ten predefined clinical variables were analyzed using univariable and multivariable logistic regression to identify independent predictors of infectious failure.

resultsMost patients (83%) had a stent in place at the time of surgery, and 78% received cefuroxime as prophylaxis. Infectious complications occurred in 29 patients (8.3%). Patients with infectious complications had significantly longer JJ stent dwell times (mean 63.9 vs. 36.3 days, p < 0.001). Multivariable analysis identified prolonged stent dwell time (OR 0.984 per day; 95% CI 0.973-0.995; p < 0.001) and neurogenic bladder (OR 0.871; 95% CI 2.196-6.739; p < 0.001) as independent risk factors for infectious failure. Subgroup analysis revealed a significant increase in infection rates when dwell time exceeded 60 days (p < 0.001).

conclusionProlonged JJ stent dwell time and neurogenic bladder are independently associated with increased postoperative infectious complications after URS. Our findings support implementing fast-track surgical protocols to reduce stent duration, particularly avoiding delays beyond 60 days, to minimize infection-related morbidity.
