Preliminary report of post-Ophira mini sling implantation voiding pattern: What to learn from pressure-flow studies?

ABSTRACT

BACKGROUND: The study is amined to correlate the voiding pattern after successful mini sling Ophira implantation with postoperative symptoms and satisfaction, in addition to identifying obstructions. MATERIALS AND METHODS: From 2012 to 2015 in a single institution, all consecutive patients who had stress urinary incontinence treated by using the mini sling Ophira had a pre- and 12 months postoperative urodynamic test. The International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-UI-SF) and the International Consultation on Incontinence Questionnaire - Overactive Bladder (ICIQ-OAB) translated into Portuguese, were given. Patients were objectively considered cured when presenting no urinary incontinence at the Valsalva test and subjectively cured when the ICIQ-UI-SF was zero. RESULTS: Questionnaire scores were obtained from 29 patients and urodynamic data from 20 patients. Mini sling Ophira implantation resulted in a significant improvement of urinary symptoms evidenced by a significant mean reduction in ICIQ-UI-SF from 16 to 5 (p < 0.0001) and ICIQ-OAB from 8 to 4 (p = 0.0001). The subjective and objective cure rates were 55% and 45%, respectively. The urodynamic changes were not related to success even when adjusted for age, hormonal status, or anterior pelvic organ prolapse. The mean maximum flow decreased to 4.9 mL/s (95% CI 0.62-10.8; p = 0.035), and the mean detrusor pressure at maximum flow increased to 11.4 cmH2O (95% CI 4-18; p = 0.0078). CONCLUSIONS: Mini sling Ophira implantation decreased maximum urinary flow and increased the detrusor pressure at the maximum urinary flow and these urodynamic changes were not related to success.
