Abstract

The aim of this research is estimating the proportion of intrinsic sphincter deficiency (ISD) by result of leak point pressure (LPP) and related factors in female stress urinary incontinence (SUI). This is the case series report, females with SUI have done multichannel urodynamic study (UDS)  at the University Medicine Center of Ho Chi Minh city from 05/2019 to 07/2021. leak point pressure (LPP) measurement was used to diagnose ISD and cut-off point according to McGuire. There were 41 women with SUI who performed LPP measurement, 35 cases were positive, 1 patient was rejected due to poor bladder compliance and decreased bladder capacity (60mL).  41.2% women with SUI had ISD according to LPP ≤ 60cmH20. ISD was not correlated with the SUI severity according to Stamey's classification. ISD was negatively correlated with urethral hypermobility (p = 0.024) and positively correlated with supine empty bladder stress test (p = 0.028). In conclusion, 41.2% women with stress urinary incontinence (SUI) had intrinsic sphincter deficiency (ISD) according to leak point pressure (LPP)  ≤ 60cmH20. ISD should be suspected when women with SUI had urethral immobility and supine empty bladder stress test positive.
