Patient-reported symptoms at follow-up after a ureteral colic attack as an indication of spontaneous stone passage/remaining ureteral stone or presence of urinary tract obstruction.

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
BackgroundPatient-reported symptoms is considered a possible alternative to computed tomography (CT) for the evaluation of remaining ureteral stones at follow-up after a ureteral colic attack.PurposeTo investigate patient-reported symptoms at follow-up after a ureteral colic attack in patients with a remaining ureteral stone and to assess the association of symptoms with degree of urinary obstruction.Material and MethodsThis was a prospective study of 81 patients (68 men, 13 women; mean age = 59 years; age range = 23-88 years) referred for a follow-up CT after a ureteral colic attack with a remaining unilateral ureteral stone. A dynamic enhanced scan defined urinary obstruction. Stone size was the largest diameter of three multiplanar reformatations (axial, coronal, sagittal). Stone location was registered as proximal, mid-ureter or distal. Symptoms were registered in standardized questionnaires by the patient at the time of the follow-up.ResultsIn total, 43/81 (53%) patients reported symptoms. Obstruction of any degree was present in 16 (20%) patients. In 7 (100%) patients with moderate-severe obstruction reported discomfort attributed to the stone. In patients with mild obstruction, 5 (56%) reported discomfort; in patients with no obstruction, 31 (48%) reported discomfort.ConclusionAlmost half of the patients at follow-up reported no discomfort despite having a stone in the ureter. A significant association was found between a higher degree of obstruction and reported symptoms. Asymptomatic stones and silent partial obstruction could be missed based on reported symptoms. Imaging is still required to evaluate stone passage at follow-up after a ureteral colic attack.
