Postoperative Symptom Severity and Time Course After Bilateral Ureteroscopy With Stents: Results From the Study to Enhance Understanding of Stent-associated Symptoms.
Observational study in Urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo assess and compare stent-associated symptoms after unilateral vs bilateral ureteroscopy with ureteral stent placement for stone treatment.
methodsParticipants enrolled in the Study to Enhance Understanding of Stent-Associated Symptoms (STENTS), a multicenter, prospective, observational cohort study, completed validated questionnaires and patient-reported outcome measures to assess stent-associated symptoms postoperatively. Patient-Reported Outcomes Measurement Information System (PROMIS) tools were used to measure pain intensity and interference due to pain, while the Ureteral Stent Symptom Questionnaire (USSQ) and Lower Urinary Tract Dysfunction Research Network Symptom Index-10 (LURN SI-10) were used to measure urinary symptoms. These data were used to determine symptom intensity and course, comparing outcomes after bilateral vs unilateral ureteroscopy.
resultsOf the 484 participants who enrolled in STENTS, 60 underwent a bilateral procedure. Patients in the bilateral group reported greater increases in pain intensity and pain interference beginning on POD 3 (P = .017 and .022, respectively), continuing through POD 7-9, with no difference in interference 30 days after stent removal, compared to the unilateral group. Urinary symptoms were worse following a bilateral compared to unilateral procedure at all time points, except for similar urinary symptoms 30 days following stent removal.
conclusionPatients undergoing bilateral compared to unilateral ureteroscopy report higher pain intensity, pain interference and urinary symptoms. Although exploratory, this analysis provides the most informative description of the patient experience with bilateral stents to date and may be useful in counseling patients considering bilateral stone treatment and in managing expectations.
