Evaluation of change in oxidative stress in urolithiasis patients following complete stone clearance: A prospective observational study.

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
Introduction: Prior studies showed that oxidative stress (OS) is increased in patients with urolithiasis. Urinary 8-hydroxy 2-deoxyguanosine (8-OHdG) is a well-established marker of OS, and its levels are elevated in patients with urolithiasis. It is unknown whether this increased OS persists even after stone removal. We aimed to evaluate the change in urinary 8-OHdG levels in patients with urolithiasis following complete stone clearance. Methods: A prospective pre-post study was conducted at a single center (Institute Ethics Committee approval: NK/5965/MS/029). Patients with urolithiasis undergoing surgery for stone clearance were included. Patients with known comorbidities, malignancy, systemic illnesses, body mass index >30 kg/m Results: Forty patients (24 males) with a mean age of 34.65 (±11.02) years were analyzed. Thirty-seven patients had renal stones, while 3 had proximal ureteral stones (median stone size = 20 mm). Percutaneous nephrolithotripsy was performed in 33 patients, while 7 underwent various other surgical procedures for stone removal. There was no significant difference in urinary 8-OHdG levels following stone clearance; preoperative 25.770 (1.47-60.38)-μg/g-creatinine versus postoperative value of 32.00 (6.57-117.35)-μg/g-creatinine; Conclusions: The baseline OS in urolithiasis patients does not change after complete stone clearance. Whether this persistent OS is responsible for stone recurrence needs to be explored.
