1 · What the graph read from it

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.

2 · The registry

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

purposeTo evaluate the clinical efficacy of transurethral thulium laser vapoenucleation of the prostate (ThuVEP) combined with the 12-o'clock urethral mucosal preservation technique for treatment of small-volume benign prostatic hyperplasia (BPH), focusing on incidences of bladder neck contracture and urinary incontinence, as well as improvements in quality of life (QoL).

methodsThis retrospective analysis included 102 patients with small-volume BPH who underwent the modified ThuVEP procedure between June 2018 and December 2024. The modified technique emphasized preservation of the urethral mucosa at the 12-o'clock position.

resultsThe mean preoperative prostate volume was 35.4 mL, mean operative time was 35 min (range, 25-50 min), and median catheterization time was 4 days. After a median follow-up of 27 months, all patients achieved satisfactory postoperative voiding. The median maximum urinary flow rate (Qmax) was 24.2 mL/s and median post-void residual volume (PVR) was 20 mL. Both postoperative the International Prostate Symptom Score (IPSS) and QoL score significantly improved (p < 0.01). Eight patients developed mild, transient urinary incontinence, which spontaneously resolved within 1 month. No bladder neck contracture occurred during follow-up.

conclusionThuVEP combined with 12-o'clock urethral mucosal preservation provides robust relief of obstructive symptoms in patients with small-volume BPH; it has a high rate of immediate postoperative urinary continence and low incidence of bladder neck contracture. This modification represents a safe and effective surgical option for small-volume BPH, although long-term outcomes should be validated in larger cohorts with extended follow-up.
