Hip Biomechanical and Functional Changes Following Transobturator Tape Surgery for Stress Urinary Incontinence.

Area of Science:

• Urogynecology
• Musculoskeletal Biomechanics
• Rehabilitation Science

Background:

• Transobturator tape (TOT) is a common surgical treatment for stress urinary incontinence.
• Groin and thigh pain are known complications, but effects on hip function are less understood.

Purpose of the Study:

• To evaluate short-term effects of TOT on hip range of motion (ROM), muscle strength, gait, and quality of life.
• To investigate biomechanical and functional changes following transobturator tape surgery.

Main Methods:

• Prospective cohort study of 33 women undergoing TOT.
• Pre- and 12-week postoperative assessments of hip ROM, muscle strength, gait (Timed Up and Go, 10-Meter Walk Test), and patient-reported outcomes (UDI-6, IIQ-7, SF-12, FJS).

Main Results:

• Significant reductions in hip internal/external rotation ROM and adduction strength were observed (p < 0.01).
• No significant changes in gait performance, SF-12, or Forgotten Joint Score were found.
• Urinary symptoms significantly improved (p < 0.001).

Conclusions:

• Transobturator tape surgery leads to measurable, albeit subclinical, biomechanical changes in the hip.
• These short-term musculoskeletal alterations did not negatively affect functional mobility or joint perception.
• Further research on long-term effects and physiotherapy interventions is warranted.
