Post-operative Urinary Dysfunction Following Shoulder Surgery: Rates and Risk Factors.

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: Post-operative urinary retention (POUR) and dysfunction are recognized complications following orthopaedic surgery. Recent literature has focused on urinary retention and its associated complications following hip and knee reconstruction and lower extremity surgery. There is a paucity of literature focusing on POUR and shoulder surgery. The purpose of this study is to describe the rates of urinary dysfunction in patients undergoing shoulder surgery as well as the associated risk factors. Methods: This was a single institution, prospective cohort study. Eligibility criteria included patients older than 50 years of age undergoing open or arthroscopic shoulder surgery. The primary outcome was the American Urological Association (AUA) symptom score (7 questions total scored 0-5, total 35 points max) administered before and after surgery. Higher scores reflect worse urinary dysfunction. Intra-operative data such as type of surgery, type of anesthesia, use of anticholinergics, peripheral nerve block, length of case, and amount of intravenous fluids were collected. Results: Of 194 patients, the mean age was 61.4 years (Standard Deviation (S.D.) = 13.0)) and the average BMI was 29.2 (S.D. = 5.6). The sample was 35.6% female. Overall, 46.4% reported worse AUA scores post-operatively within the first 3 to 5 days, including 4.1% of which were clinically defined as "moderately worse" (>5 point worse) or "much worse" (>11 points worse). Worse preoperative AUA scores correlated with worse postop AUA score on linear regression analysis (r=0.883, Conclusion: Worsening of urinary function following shoulder surgery is common. The AUA score may be used to identify at-risk patients and to track changes in urinary function post-operatively. Men with a diagnosis of BPH are at particularly high risk. Further investigation is needed to elucidate the impact of urinary dysfunction on patient outcomes, satisfaction, and cost as well as the role of prophylactic medications.
