Participants	67 women with SUI were randomised. Basline comparison of age, menopause status, parity, SUI, mixed incontinence and intrinsic sphincter dysfunction were made Inclusion criteria: type II‐IV SUI, mixed SUI, intrinsic sphincter dysfunction, or failed previous operations Mixed incontinence was included in this study
Interventions	A (19): autologous fascia lata pubovaginal sling B (48): TVT
Outcomes	Cure rates and operative morbidity Damage to bladder, urinary retention, difficulty voiding Incontinent at 3 months: A: 1/19, B: 3/48 Not improved at 3 months A: 0/19, B: 0/48 Operative time (SD): A: 125 (13), B: 27 (5) min Mean length of hospital stay: A: 7.2, B: 1.8 ds Mean time to catheter removal: A: 5.3, B: 1 ds Complications: voiding dysfunction: A: 3/19, B: 3/48; urinary retention: A: 2/19, B: 0/48; bladder injury: A: 0/19, B: 2/48; detrusor overactivity: A: 1/19, B: 3/48
Notes	Follow‐up on average was between 20‐37 months. Cure rates assessed at 3 months Full text was translated from Chinese
