How do clinicians distinguish UTI-related retention from bladder outlet blockage?
The short version: the evidence here does not answer how clinicians distinguish UTI-related retention from bladder outlet blockage.
The retrieved records are almost entirely about other questions. One study on noninvasive predictors of bladder outlet obstruction in men with benign prostatic enlargement found that intravesical prostatic protrusion, detrusor wall thickness, prostate volume, and PSA levels could predict obstruction [6]. That is the closest match, but it studied men with known prostate enlargement, not the distinction between UTI and obstruction. A case report described a pelvic hydatid cyst causing acute urinary retention in a young woman [8], which is a rare mechanical obstruction, not a UTI.
The rest of the evidence covers catheter colonization rates [1], urethral bulking agents for stress incontinence [2], bladder scanner accuracy [3], postoperative catheter management [4], kidney transplant outcomes [5], drug trials for overactive bladder [7, 9], a surgical technique for prostate resection [10], dipstick urinalysis interpretation [11], and a prediction model for retention after prolapse surgery [12]. None of these compare UTI-related retention to bladder outlet obstruction.
Outside this retrieval, the clinical distinction is well documented. The key tools are history, physical exam, urinalysis, and post-void residual measurement. A man with a large prostate on digital rectal exam, a history of slow stream and hesitancy, and a negative urinalysis likely has obstruction. A woman with dysuria, fever, leukocyte esterase and nitrites on dipstick, and no prior voiding symptoms likely has UTI-related retention. A bladder scanner or catheter can measure post-void residual, but it does not distinguish cause. Urodynamic studies can confirm obstruction but are rarely used in acute settings.
My call: the evidence here does not address the question. Confidence: not clear, because the retrieval missed the relevant diagnostic literature entirely.

COMPARISON OF LATEX AND SILICON INDWELLING CATHETER IN TERMS OF RATE OF BACTERIAL COLONIZATION IN MALES WITH ACUTE URINARY RETENTION AT 5TH DAY OF CATHETERIZATION
This study compares the rate of bacterial colonization between latex and silicone indwelling catheters in males with acute urinary retention, finding that silicone catheters significantly reduce bacterial growth compared to latex catheters by the fifth day of catheterization.

Urethral bulking agents for the treatment of stress urinary incontinence in women: A systematic review
This systematic review found that newer synthetic urethral bulking agents were not inferior to Contigen for short-term subjective success, Bulkamid appeared safe with no erosion or migration, but adverse events varied by agent and Bulkamid was inferior to TVT.

Is urinary drainage necessary during continuous epidural analgesia after colonic resection?
Early removal of urinary drainage after 24 hours in colon resection patients on 48-hour thoracic epidural analgesia yields low rates of urinary retention and urinary infection, suggesting routine catheterization beyond day 1 may be unnecessary.
