Abstract

Various prognostic factors which could be implicated in late complications associated with intraurethral stents and coils were evaluated. A consecutive series of 107 subjects with BPH or prostatic cancer who required intraurethral stents and randomly received either the Prostakath® or Urospiral® type were followed for 2-7 years. Data on stent-associated complications were collected. Factors directly associated with the complication rate were the pre-treatment presence of an indwelling catheter and asymptomatic bacteriuria, as well as post-treatment low urinary flow rate. Stent type and length did not influence outcome. It is concluded that in selected patients, either of the two studied intraurethral stents is a feasible and durable treatment. Men with indwelling catheters and/or bacteremia are at high risk of complications (e.g. migration, stone formation, strictures), as are those with post stent insertion low uroflow. Although stents may be left in situ for years, these subgroups of men should be closely monitored to detect early signs of complications.
