Urodynamic and urethral pressure profilometry findings in women with voiding phase dysfunction treated with surgical urethrolysis.

Long-term urodynamic (UDS) and urethral pressure profilometry (UPP) parameters in women with voiding phase dysfunction following an anti-incontinence (AI) procedure have been poorly characterized. We report our 10-year UDS findings in women with voiding phase dysfunction after AI procedure, who underwent urethrolysis. We identified sequential records containing urethrolysis current procedural terminology codes over a 10-year period. Records of women with preoperative UDS were reviewed for demographics, UDS tracing, and outcomes following urethrolysis. Twenty-five women (mean age 60 years) had voiding phase dysfunction and underwent urethrolysis at a mean of 47 months (interquartile range [IQR] 12-61) after AI procedure. Preoperatively, six (24%) women required intermittent catheterization. Free uroflowmetry revealed a mean maximum peak flow (Qmax) of 9.6 ml/s (IQR 7.0-11.0), voided volume of 137 ml (IQR 81-169), and postvoid residual of 167 ml (IQR 43-288). UDS revealed a mean UPP length of 24 mm (IQR 20-27), UPP closure pressure of 78 cmH UPP may help characterize outlet parameters in women with voiding phase dysfunction following an AI procedure, who ultimately undergo urethrolysis.
