Development of Prediction Models for Severe Pain and Urinary Symptoms After Ureteroscopy With Ureteral Stent Placement: Results From the STENTS Study and Initial Validation of Pain Interference.
Article in The Journal of urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeWe developed prediction models for severe pain and urinary symptoms after ureteroscopy with ureteral stent placement. MATERIALS AND
methodsThe development cohort included 424 adults and adolescents enrolled in the multicenter STENTS prospective cohort study who underwent ureteroscopy with stent placement for urinary stones. The validation cohort was an independent prospective cohort of 115 adults. The outcomes were severe pain intensity and pain interference, measured by the Patient-Reported Outcomes Measurement Information System, and severe urinary symptoms, measured by the Ureteral Stent Symptom Questionnaire. The top quartile of symptoms on postoperative days 1 and 3 was defined as severe. Generalized estimating equation models were used to predict severe symptoms on postoperative days 1, 3, 5, and 7 to 9 in the development cohort and severe pain interference on days 1 and 7 in the validation cohort.
resultsFemale sex, younger age, higher BMI, baseline pain interference, number of chronic pain conditions, renal stone location, and history of anxiety predicted severe pain. In the development cohort, the C statistics were 0.83 (95% CI 0.80-0.85) for severe pain interference and 0.82 (95% CI 0.79-0.84) for severe pain intensity. A model in which baseline urinary symptoms replaced pain interference had excellent discrimination for severe urinary symptoms (C statistic 0.83; 95% CI 0.81-0.85). In the validation cohort, the C statistic was 0.7 for severe pain interference (95% CI 0.54-0.78).
conclusionsPreoperative characteristics accurately predicted severe pain and urinary symptoms after ureteroscopy with stent placement. On further validation, these models could guide clinical decisions to improve surgical outcomes.
