[Management of ureteral obstruction and neurogenic bladder in cancer patients]

Urinary tract management is very important for preventing cancer patients from deterioration of their upper tract and their quality of life. Percutaneous nephrostomy or retrograde ureteral stent is a selected procedure used for overcoming ureteral obstruction in many cases. It is advisable that the advantages and disadvantages of these procedures be fully considered. On the other hand, patients with neurogenic bladder should be evaluated initially by means of non-invasive examinations, which must involve uroflowmetry and measurements of residual urine. High intravesical pressure during the storage and/or voiding phase often leads to upper tract deterioration. In particular, bladder expression(forceful straining on void)should be allowed only when it is urodynamically safe.
