BPH
Conditions
Brief summary
Subjects with AUR secondary to BPO that comply with Inclusion/Exclusion Criteria. A total of 50 eligible subjects will be recruited into the study to receive treatment with iTind system. Study duration will be 12 months post implantation, with follow-up extension of up to 3 years. Extension of follow up period will not require an additional ICF.
Detailed description
Spontaneous acute urinary retention (AUR) is one of the most significant complications of long-term benign prostatic hyperplasia (BPH). In the past it has represented an immediate indication for surgery. Between 25% and 30% of men who underwent transurethral prostatectomy (TURP) had AUR as their main indication in older series and today most subjects failing to void after attempted catheter removal still undergo surgery. For this reason alone, AUR is an important and feared event from the viewpoint of the subject. The subject originally has inability to urinate, with increasing pain, and eventually a visit to the emergency room, catheterization, follow-up visits to the physicians, an attempt at catheter removal, and eventual recovery or surgery, which is both painful and time consuming. After the acute period most men with AUR will be offered a 'trial without catheter' (TWOC) and about half will resume spontaneous voiding. Most men who fail a TWOC, experience a recurrent episode of AUR, or have moderate or severe lower urinary tract symptoms (LUTS) that are refractory to medical management will be considered for surgery. In the older literature, the risk of recurrent AUR was cited as 56% to 64% within 1 week of the first episode and 76% to 83% in men with diagnosed BPH. (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1476058/). Additional researches show that ten percent of men in their seventies and 30% in their eighties will have AUR within the next five years. Benign prostatic hyperplasia is the cause for the AUR in at least 65% of men presenting with AUR. In the below study of the natural history of BPH, the risk of AUR was 1.6% at five years for men aged 40-49 years and 10% at 70-79 years.
