The resected prostate weight matters in transurethral resection of the prostate in men with benign prostatic hyperplasia.
Article in BMC urology, 2025. 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
backgroundAlthough a notable proportion of patients report improvement in clinical outcomes following transurethral resection of the prostate (TURP), symptoms persist in about 25% of cases, resulting in dissatisfaction with the treatment. Due to this dissatisfaction, several studies have been conducted to determine the parameters that can predict outcomes. These parameters include the resected weight and the resected weight fraction. However, there is ambiguity as to what constitutes an adequate resection. Even more, the effect of the resected weight on clinical outcomes in African men with benign prostatic hyperplasia (BPH) is limited. Relevant data is needed to improve clinical practice. This study aims to determine the effect of the resected prostate weight on clinical outcomes in men with BPH at the Korle Bu Teaching Hospital (KBTH).
methodsThis study uses the International Prostate Symptom Score (IPSS), Quality of Life (QoL), International Index of Erectile Function-5 (IIEF-5) questionnaires, Peak Flow Rate (PFR) and Post Void Residual (PVR) urine volume to assess the clinical outcomes among men with BPH undergoing TURP at the KBTH. A cross-tabulation analysis evaluated the impact of the resected weight on the clinical outcome variables. Pearson and Spearman correlation methods ascertained the correlation between the post-operative PFR and the prostate weights, while receiver operator characteristic models interrogated the relationship between resected weight models and the clinical outcome variables. A total of 52 patients were recruited with an average of 5 recruited per month, using consecutive sampling.
resultsThe mean age was 66.83 ± 8.67 and failed medical therapy was the main indication for surgery (65%). The mean resected weight was 10.53 ± 6.98 g and the average resection speed was 0.13 g/minute. Resected weights, 20% or less of the prostate volume were much less effective. As the resected fraction doubles, the improvement in the peak flow rate also doubles. Although the resected weight and the resected weight fraction curve models were both effective in predicting voiding outcomes, the resected weight fraction had a better predictive value.
conclusionThe improvement in voiding function following TURP is dependent on the resected weight as it doubles the improvement in voiding function. Resections greater than 30% of the prostate weight are sufficient to restore normal voiding function.
