Painless Ischemic Priapism Associated With Tamsulosin Use: A Case Report and Literature Review.
Article in Cureus, 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
Tamsulosin, a selective α1-adrenergic antagonist prescribed for benign prostatic hyperplasia and expulsion of ureteral stones, carries a rare risk of priapism. We present a 59-year-old male with hypogonadism, hypertension, and hyperlipidemia who developed painless priapism 72 hours after initiating tamsulosin for ureterolithiasis. Despite the atypical absence of pain, penile blood gas analysis confirmed ischemic priapism. Initial treatment with intracavernosal phenylephrine (1000 mcg) failed, requiring bilateral corpus spongiosum shunts for resolution. A literature review revealed that many of the 14 existing cases identified occurred within 24 hours of drug initiation in middle-aged or older patients without additional risk factors. Approximately half responded to intracavernosal vasoconstrictors, while refractory cases required surgical intervention. To our knowledge, this is the first reported case of painless tamsulosin-induced ischemic priapism, emphasizing the importance of patient counseling and prompt evaluation of persistent erections regardless of pain intensity.
