Prostatic calculi in men with chronic prostatitis and chronic pelvic pain syndrome: A systematic review (2015-2025).
Review in Urology annals. 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
Prostatic calculi are frequently detected on transrectal ultrasound (TRUS) and computed tomography (CT), yet their clinical relevance in prostatitis remains uncertain. To systematically evaluate the association between prostatic calculi and prostatitis-related outcomes in adult men. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic review was conducted. PubMed, Ovid Embase, CINAHL, and Google Scholar were searched for studies published between January 1, 2015 and October 31, 2025. Eligible studies assessed prostatic calculi by presence, burden, location, or density and compared outcomes with men without calculi or with lower burden. Outcomes included prostatitis diagnoses, validated symptom measures (National Institutes of Health-chronic prostatitis symptom index [NIH-CPSI], International Prostate Symptom Score [IPSS], International Index of Erectile Function - 5), inflammatory markers, and treatment response. Risk of bias was assessed using the Critical Appraisal Skills Programme tool. A total of 198 records were identified, of which 10 studies were included. Most were cross-sectional, with one prospective CP/chronic pelvic pain syndrome cohort. Greater calcification burden and peri-urethral distribution were associated with higher NIH-CPSI and IPSS scores and less favorable symptom improvement following medical therapy. CT-based cohorts reported associations between higher-density calculi and worse lower urinary tract symptoms, erectile dysfunction, pelvic pain, and reduced quality of life. A prostatectomy series demonstrated bacterial biofilm within calcifications, providing biological plausibility. Prostatic calculi - particularly when extensive or peri-urethral - are associated with increased symptom burden and may identify men with more refractory disease. However, current evidence is observational and heterogeneous, with incomplete confounder control. Standardized imaging classifications and prospective studies are required to clarify causal relationships and inform management strategies.
