Very long-term follow-up of autologous pubovaginal fascia slings in women with stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS

The objective was to report on the very long-term outcome of a published series of autologous pubovaginal slings (PVS) in women with stress urinary incontinence (SUI).

METHODS

Following institutional review board approval, a cohort of well characterized, non-neurogenic women who underwent an autologous PVS (primary [PVS1] and secondary [PVS2]) for SUI was re-evaluated for their very long-term outcome status. Data collected included demographics, validated questionnaires (Urogenital Distress Inventory - short form [UDI-6], Incontinence Impact Questionnaire - short form 7, quality of life), SUI retreatment/operations, and subjective patient-reported SUI improvement (%) and symptom recurrence. The primary outcome was success defined as UDI-6 question 3 (SUI) ≤ 1 and no SUI retreatment/operation. Patients not seen in clinic for 2 years were contacted via a standardized phone interview.

RESULTS

From 83 patients with 7-year intermediate follow-up data, 34 (PVS1 = 18, PVS2 = 16) had very long-term follow-up based on clinic visit (7) or phone interviews (27). Those lost to follow-up (49), including 5 deceased, did not differ in demographics and intermediate outcomes from the followed cohort, but lived further away (>75 miles). At a mean age of 74 years, and with a median follow-up of 14.5 years, 53% met the success criteria (PVS1 = 44%, PVS2 = 63%). Mean postoperative questionnaire scores did not differ significantly between intermediate and very long-term follow-ups, and long-term outcomes between PVS1 and PVS2 remained similar.

CONCLUSIONS

A majority of women with long-term follow-up after PVS for primary and secondary SUI remained successful more than 14 years after their surgery. Both groups, PVS1 and PVS2, fared equally well, confirming the durability of PVS as a treatment alternative for SUI.
