Delayed hematuria after prostatic photovaporization: risk factors to know.
Article in World journal of urology, 2024. 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
objectivecharacterize delayed hematuria (DH) after photoselective vaporization of the prostate (PVP) and identify its associated risk factors.
methods1014 patients who underwent PVP at an expert center, from September 2005 through December 2021, were prospectively enrolled in a database registry. Risk factors of DH included age, prostate volume, ASA score, history of BPH surgery, history of prostate cancer, use of anticoagulation or 5ARIs, concomitant procedure, operative factors, and the duration of follow-up.
resultsThe median operating time was 60 ± 11 min. The median specific applied energy was 318,500 Joules ± 101,347. After PVP, the mean catheterization duration was 1.6 days with a postoperative hospitalization time of 1.8 days. The median follow-up was 52 months (range 2-95 months). Hematuria occurred in 206 patients (20.3%), with 10% requiring an ER visit and 8.3% requiring hospital admission, transfusion or endoscopic clot removal. Almost 80% of hematuria episodes occurred within the first 3 months. The overall retreatment rate for clot retention was 3.7% after a mean time of 50 months. Hematuria-free survival was 97.2% after 1 year, and 89.3% after 4 years. Delayed hematuria occurred in 32 patients (3.1%). In the multivariate analysis, age, preoperative prostate volume, anticoagulant use, total applied energy, lasing time and operative time were identified as risk factors for delayed hematuria after PVP.
conclusionLarger prostate volume, longer operative time, longer lasing time, and use of oral anticoagulation increase the odds of delayed hematuria after PVP, while older age is protective.
