Feasibility of serial perioperative lung ultrasound to monitor fluid shifts during thulium laser prostate enucleation.
Observational study in World journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeIrrigation fluid absorption (IFA) during transurethral surgery of the prostate continues to pose a risk for fluid overload and electrolyte imbalance, yet reliable methods for quantifying absorption remain limited. Lung ultrasound (LU), increasingly used to detect pulmonary pathology, provides a noninvasive approach to assess fluid accumulation.
methodsIn this prospective single-center observational study, 36 patients aged ≥ 60 years undergoing elective urethral-sparing Thulium: YAG anatomical endoscopic enucleation of the prostate (AEEP; ThuLEP) were examined. LU was performed preoperatively and postoperatively by trained investigators, and a modified Lung Ultrasound Score (mLUS) was calculated. Perioperative data included body weight, fluid balance, biochemical parameters, and hemodynamic variables. Associations between mLUS and perioperative parameters were evaluated using Spearman correlation and linear regression analyses.
resultsMedian postoperative mLUS values increased significantly from baseline (0 (IQR 0-1) vs. 7.5 (IQR 4.5-10.5), p < 0.0001). Overall fluid balance correlated with both postoperative mLUS (ρ = 0.51, p = 0.003) and change in mLUS (ρ = 0.40, p = 0.023). The change in body weight correlated with intraoperative fluid balance (ρ = 0.66, p < 0.001), overall fluid balance (ρ = 0.58, p < 0.001), and serum chloride increase (ρ = 0.53, p = 0.007). In a simple linear regression model, overall fluid balance was associated with the change in mLUS (β = 0.00073, 95% CI 0.00015-0.00131, p = 0.015). In a multivariable linear regression model, greater overall fluid balance (p = 0.015) and chloride increase (p = 0.001) were associated with larger increases in body weight. The median weight of removed prostate tissue was 61.5 g (IQR 42-88.5), with 0.92 g per minute.
conclusionLU detected postoperative pulmonary fluid accumulation and correlated with perioperative fluid balance in elderly patients undergoing AEEP. Changes in serum chloride concentration and body weight were associated with systemic fluid uptake.
