Clinical and demographic factors associated with valsalva leak point pressure among women undergoing burch bladder neck suspension or autologous rectus fascial sling procedures

Abstract

Advancing age, lower BMI, higher maximum flow rate, and lower voiding pressures are all independently associated with lower VLPP in women undergoing surgery for SUI. Lower voiding pressures and higher flow rates among women with more severe SUI may reflect the chronic loss of urethral resistance associated with SUI. Interestingly, urethral hypermobility as assessed by Q-tip testing angle does not achieve a statistically significant association with VLPP on multivariate testing when controlling for POP-Q stage. Thus, as clinically suspected, the Q-tip test is not predictive of VLPP in women with urethral hypermobility and SUI.
