Total continence\cost
Who the best candidate for the sling? Mild and average forms of urinary incontinence (pad-test no more than 400 ml) Presence of residual sphincter function: - ability to reach the toilet with a sufficient volume of urine (200 ml) - ability to close urination - "Dry" night - better continence of urine daytime Who the best candidate for the sling?
Who the best candidate for the sling? Better continence of urine with prolonged sitting than when standing and walking Exclusion of urethral strictures and / or vesico-urethral anastomosis (urethrocystoscopy) Exclusion of overactive bladder (cystometry) Exception of hypo contractility detrusor ("pressure-flow")
Artificial urinary sphincter (AUS) Artificial urinary sphincter (AUS) - «gold standard" surgical treatment of male urinary incontinence Year-to-market: 1973 First publication: 1974 (Scott F.B. et al.) The highest efficiency (average 79%) Recommended for severe urinary incontinence A U S Fulford S.C. et al., 1997; Hajivassiliou C.A., et al., 1999; Venn S.N. et al., 2000; Trigo Rocha F, et al., 2008; Bauer R.M. et al., 2009
Artificial urinary sphincter But! Expensive Patient must be mentally and physically able to handle the sphincter Risk in urgent situations (when the patient is unconscious and can not tell the artificial sphincter) High risk of re-revision and replacement of spincter (mechanical damage, infection, erosion) - 37 - 80% Fulford S.C. et al., 1997; Hajivassiliou C.A., et al., 1999; Venn S.N. et al., 2000; Trigo Rocha F, et al., 2008; Bauer R.M. et al., 2009
Conclusions Sphincteric deficiency as a result of operations on the prostate - the main cause of stress urinary incontinence in men; Radical prostatectomy - the most common operation is the development of stress urinary incontinence;
Conclusions For early PPSUI recommended non-invasive methods of treatment. The combination of pelvic floor muscles training (PFMT) with duloxetin - the most effective; Injection therapy is not widely used because of its low clinical efficacy, the need for repeated injections and the relatively high cost;
Conclusions Patients with mild to moderate urinary incontinence sling surgery are recommended. For patients with severe incontinence recommend implantation of artificial sphincter, which is still the "gold standard" treatment for men with PPI, despite the high risk of complications.
