Association Between Cigarette Smoking and Early Improvement in Lower Urinary Tract Symptoms After 180-W GreenLight Photoselective Vaporization of the Prostate: Findings From a Dual-Center 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
purposeThis study aimed to evaluate the association between smoking status and early postoperative urinary symptoms following photoselective vaporization of the prostate.
methodsWe conducted a retrospective study at two institutions in Japan. Patients who underwent photoselective vaporization of the prostate between 2020 and 2025 were classified as never-smokers, ex-smokers, or current-smokers. Baseline characteristics and surgical parameters were collected. Treatment outcomes were assessed using the International Prostate Symptom Score and the Overactive Bladder Symptom Score preoperatively and at one and 3 months after surgery. Multivariable analysis was performed to estimate the impact of smoking on low postoperative improvement, adjusting for covariables. A subgroup analysis evaluated voiding urodynamic parameters in patients with available data.
resultsA total of 282 patients were included. Current-smokers showed significantly higher total International Prostate Symptom Score and its voiding subscore than other groups postoperatively. The storage subscore and Overactive Bladder Symptoms Score were similar among groups postoperatively. Current-smokers were more likely to require newly prescribed medication for overactive bladder symptoms within 1 month. Quality-of-life-scores were also worse in current-smokers at 1 month postoperatively. Multivariable analysis indicated that lower International Prostate Symptom Score and current smoking were independently associated with low postoperative improvement in the total International Prostate Symptom Score. No significant differences in urodynamic parameters were observed among groups.
conclusionsCurrent smoking was associated with worse early urinary symptoms and quality-of-life-scores following photoselective vaporization of the prostate. Smoking cessation before surgery may help improve postoperative outcomes.
