Aim:
The aim of this study was to review recent literature on mini-invasive surgical technique for the treatment of female stress urinary incontinence (SUI). Surgical aspects, intraoperative and perioperative complications and objective and subjective outcomes were analyzed and compared.
Methods:
The PubMed databank from 2000 to February 2007 was searched for original prospective and randomized studies in English, on surgical treatment of female SUI, which avoided a laparotomic access to the female pelvis. Studies had to investigate at least 40 women with a minimum follow-up of 12 months.
Results:
A total of 38 prospective studies were found: 27 of them were on mid-urethral slings; 8 assessed urethral injections; and 3 radiofrequency treatment. Fifteen studies were randomized. Follow-ups ranged from 12 to 60 months, except for sexual function which had a 6-month follow-up. Ten out of 38 studies assessed patients who did not refer pelvic organ prolapse or detrusor overactivity and had not undergone any previous anti-incontinence procedure.
Conclusion:
Mid-urethral slings showed good outcomes and are safe and brief to perform and have a relatively short learning curve. Urethral injections showed discouraging results, as they have poor outcomes and repetitive treatments are frequently necessary. Injections can be used in women with contraindications to major surgical procedures, with intrinsic sphincter deficiency as the main cause of incontinence. Radiofrequency showed worse results than mid-urethral slings and is a valuable choice in women who refuse more invasive procedures. The development of studies with longer follow-ups on mini-invasive surgical techniques are encouraged.
