| Public title | A Randomised Controlled Trial to Assess the Effectiveness and Cost Effectiveness of TURP, Laser and Watchful Waiting in the Treatment of Bladder Outflow Obstruction |
| Scientific title |
|
| Acronym | The CLasP Study |
| Disease/condition/study domain | Urological and genital diseases: Other urological and genital disease |
| Study hypothesis | Ten to fifteen percent of men aged 40 undergo transurethral prostatectomy (TURP) in their lifetime.
About 20% do not achieve satisfactory symptomatic results, 5% to 10% suffer major morbidity and 0.2% to 1% die from the procedure. The annual cost of TURP in the USA is in excess of $3,000,000,000. New, less invasive treatments are now available including laser treatment which may be provided as a day-case procedure. It is unclear how laser treatment compares with TURP or indeed with conservative treatment (watchful waiting - reassurance and advice) in terms of cost, effectiveness, improvement in quality of life and urodynamic outcome. These deficiencies in knowledge are clearly very important to the NHS which cannot afford to take up high cost, high technology treatments unless they are shown to be of clear benefit. We propose carrying out a randomised controlled trial comparing TURP, laser treatment and watchful waiting in men who would normally undergo TURP. |
