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
introductionBenign prostatic hyperplasia is one of the most common medical problems. It can be treated with holmium laser enucleation of the prostate (HoLEP), which provides efficacy with few complications and a short hospitalization. A more recent evolution of this technique is minimally invasive laser enucleation of the prostate (MiLEP), using smaller sheaths, which aims to further reduce urethral trauma while maintaining surgical efficiency.
objectiveThis study set out to compare HoLEP and MiLEP interventions in prostate enucleation to assess the impact of instrument miniaturization on surgical efficiency.
methodsIn this observational study, we analyzed patients undergoing prostate enucleation in the Minimally Invasive Urology Service at Hospital Angeles del Carmen. Patients were recruited from March 1 to July 31, 2025. We included patients with a prostate volume ≤ 80 cc, International Prostate Symptom Score (IPSS) value >8, and an American Society of Anesthesiologists (ASA) Staging of I or II, and excluded those with a history of bladder pathology, prior urinary catheterization, or urolithiasis. Epidemiological and clinical variables and surgical intervention were evaluated. Statistical analysis was descriptive, and medians were compared with the Mann-Whitney U test.
resultsA total of 40 patients were included, and the HoLEP and MiLEP techniques were compared. The median age was 68 years, IPSS 21, and prostate tissue 24 gr. Enucleation time was longer in the subgroup of HoLEP (p=0.01). Surgical time was shorter in the subgroup of MiLEP (p=0.01). No differences were observed in morcellation time, enucleated tissue weight, enucleation efficiency, and morcellation efficiency. A trend toward shorter hemostasis time was observed in MiLEP, though this trend did not achieve statistical significance.
conclusionMiniaturized instrumentation using a 22 Fr sheath in MiLEP is comparable to the standard 26 Fr sheath in HoLEP in terms of surgical efficiency and safety. The smaller sheath may provide additional advantages. Further studies with longer follow-up are needed to evaluate the long-term functional outcomes.
