A 7\u2010Fr air\u2010filled dual\u2010balloon catheter was used to record vesical pressure and urethral pressure at the external sphincteric urethra. Detrusor pressure and sphincteric urethral pressure were recorded simultaneously during filling and voiding. Voiding\u2010phase fluoroscopic images were reviewed as contemporaneous anatomical correlation for pressure\u2010based interpretation. Feasibility outcomes included technical completion, interpretability of pressure recordings, suspected catheter displacement, premature termination, and procedure\u2010related adverse events. Findings were analyzed descriptively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 32 patients were included in the analysis. The cohort included 3 males and 29 females, with a mean age of 32.6 years; range, 18\u201368 years. One patient had a sacral spinal cord injury, whereas the remaining patients had no documented neurological disorder. Synchronous bladder\u2013urethral pressure measurement was completed in all 32 patients, with no premature termination or procedure\u2010related adverse events. During voiding, four pressure\u2013fluoroscopy patterns were identified: impaired external sphincter relaxation during detrusor contraction in 12 patients; preserved sphincter relaxation with effective voiding in 6 patients; preserved sphincter relaxation with detrusor contraction but no urine flow, suggesting non\u2010sphincteric outlet obstruction in 4 patients; and sphincter relaxation without evident detrusor contraction, suggesting detrusor underactivity or functional inhibition in 8 patients. Two recordings showed an unexpectedly low urethral pressure pattern during filling, suggesting probable catheter displacement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Air\u2010filled catheter\u2010based synchronous cystosphincterometry was technically feasible in this preliminary single\u2010center experience and allowed real\u2010time characterization of detrusor\u2010external sphincter pressure relationships. Fluoroscopic correlation supported the anatomical plausibility of pressure\u2010defined sphincteric relaxation and non\u2010relaxation patterns. Therefore, this method may provide a simplified adjunctive pressure\u2010based assessment tool for evaluating detrusor\u2010external sphincter coordination, particularly in centers where fluoroscopy or external urethral sphincter electromyography is unavailable. However, prospective studies with standardized feasibility metrics, reproducibility assessment, and direct comparison with established reference standards are required before its independent diagnostic accuracy can be defined.<\/jats:p>\n
