Objective: Due to the increasing numbers of radical prostatectomy performed for prostate cancer,a substantial and increasing number patients suffer from postoperative urinary incontinence and also erectile failure.Despite the improving surgical techniques,the reported incontinence rates are between 5%and 48%.In patients with dual problems of ED and incontinence,to see whether inflatable penile prosthesis implantation could control the urinary incontinence also.The hypothesis was that progressively inflating penile prosthesis could increase the intraurethral closing pressure to prevent urinary leakiage.Methods: From March 2010 up to May 2015,25 patients with postradical prostatectomy were referred to our clinic.Seven patients were complained ED only and 18 patients were with persistent urinary incontinence and ED.Inflatable penile prosthesis were implanted in all patients.From one month after operation progressively partial or full inflation were done to control urine leaking.Self-reported results were analysed.Results: In 13 patients with mild or moderate incontinence group,every patient became dry by partial inflations(30-50%)and every one reported satisfactory outcomes.In 5 severe with total incontinent groups,4 patients could tolerate incontinence by more than 90%full inflation.Only one patient received 2ndary artificial sphincter implantation.Conclusions: Urinary incontinence could be controlled by inflating inflatable penile prosthesis by increasing intraurethral closing pressure to prevent leaking.Inflatable penile prosthesis should be considered as an initial surgery,especially in patients with dual problems of ED and incontinence.
