Role of Preoperative and Postoperative Endovaginal Ultrasound and 24 h Pad Test in Evaluation of Efficacy of Various Treatment Modalities for Stress Urinary Incontinence

Abstract

Background Stress urinary incontinence (SUI) is a common problem affecting the quality of life of women. Materials and Methods It is a prospective study conducted over 40 women of SUI by endovaginal ultrasound on rest and Valsalva preoperatively and 6 months postoperatively for levator hiatus (LH), pubovisceral thickness, urethral length, and bladder neck (BN) position. A 24 h pad test was also performed on all women at the same time for grading of SUI. Treatment given was medical in 4 (10%), Burch colposuspension in 18 (45%), and tension-free obturator tape in 18 (45%). Results The mean age, parity, and body mass index in the study were 41.60 years, 2.73, and 24.2 kg/m2, respectively. All 40 (100%) patients had SUI with a mean duration of symptoms being 4.04 years. On 24 h pad test, mild SUI was in 4 (10%), moderate SUI in 33 (82.5%), and severe SUI in 3 (7.5%) with mean preoperative 24 h pad test being 36.69 g which significantly reduced to 9.79 g postoperatively (P = 0.001). There was significant change in LH and pubovisceral thickness with treatment of SUI. Overall urethral length increased but there was significant decrease in urethral length on Valsalva after the treatment (0.40 cm vs. 0.28 cm, P = 0.04) and significant reduction in BN descent after Valsalva after treatment (0.41 cm vs. 0.27 cm, P = 0.001). Conclusion Endovaginal ultrasound and 24 h pad test are the useful diagnostic modalities for SUI diagnosis and to see the impact of treatment.
