Abstract
Introduction and hypothesis
To study the surgical outcomes and risk factors for failure of three types of mid urethral slings(MUS) surgeries in elderly and old age women with urodynamic stress incontinence(USI).
Methods
Three different types of MUS surgeries [single incision sling(SIS), trans-obturator tape(TOT), retro-public mid-urethral sling-tension-free vagina tape (TVT)]were performed among three age groups of women (young <64 yr, elderly 65-74 yr and old >75 yr) with USI. They were followed up for 1 year.
Results
Complete postoperative data was available for 688 women. After 1 year, overall objective cure rate was 88.2% and subjective cure rate was 85.9%. Among the young, elderly, and old age women objective cure rates were 91.0%, 80.6%, 66.7% and subjective cure rates were 89.2%, 77.6%, 58.3% respectively. Urodynamic parameters demonstrated flow rate, higher post-void bladder residual, smaller cystometric capacity, and lower maximum urethral closure pressure were significantly lower among old and elderly group. Subjectively, urinary distress inventory-6 (UDI-6) and incontinence impact questionnaire-7(IIQ-7) improved significantly in all groups with significant changes from baseline only in older women. Intrinsic sphincter deficiency(ISD) was found to be significantly associated with failure in older women. Other preoperative comorbidities were equally distributed among all the three age groups. The operative time, perioperative complications, and length of hospital stay showed no difference between the study groups.
Conclusions
MUS surgery is safe for the young and aging patients with USI and demostrated significant improvement in its outcomes, but objective and subjective cure rates decreases with age. ISD was also found to be significantly associated with failure.
