Ureteral Stenting
OBSTRUCTION FROM MALIGNANCY
Median survival when obstructed from malignancy is 6-8mo. (2,3) Metallic stents can function for 1-3 years and are more cost effective in the long run; however, if patient prognosis is <1 year, there is no cost effectiveness. This article is a good review of the available metallic stents. (1)
PAIN FROM URETERAL STENTING
A meta-analysis showed tamsulosin and solfenacin combined was superior for stent related complaints. (4) A nonrefluxing ureteral stent without a curl in the bladder improved patient comfort and quality of life in a study. (6)
UROSEPSIS
In one study 462 patients were evaluated, there was 17x risk of urosepsis if pos preop urine culture that was treated, and a higher rate of urosepsis if no preoperative stent was used. ()
