Electrical Pudendal Nerve Stimulation as an Initial Neuromodulation Strategy for Neurogenic Urinary Retention.
Article in European urology open science, 2026. 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
Background and objective: Chronic neurogenic urinary retention often requires assisted emptying and remains challenging to treat. We evaluated whether electrical pudendal nerve stimulation (EPNS) improves bladder emptying and compared short-term outcomes with a standard sacral neuromodulation (SNM) test stimulation strategy. Methods: In this prospective, multicenter, assessor-masked study, 70 adults with chronic refractory neurogenic nonobstructive urinary retention received either EPNS (12 sessions over 4 wk) or a standard 4-wk continuous SNM test phase using a percutaneously placed S3 lead. The primary outcome was the percentage change from baseline in postvoid residual urine volume (PVR) at 4 wk. Secondary outcomes included changes in International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms and Quality of Life scores. Analyses used linear mixed models; propensity score matching was prespecified as a sensitivity analysis. Key findings and limitations: At 4 wk, the adjusted PVR improvement rate was 68% with EPNS versus 51% with SNM (between-group difference 17 percentage points; 95% confidence interval 5-29; Conclusions and clinical implications: Outpatient EPNS produced clinically meaningful short-term improvements in bladder emptying and patient-reported outcomes without implantation, supporting consideration of EPNS as an initial step in a stepped neuromodulation pathway for neurogenic urinary retention.
