title: Transurethral microwave thermotherapy (TUMT) with the Targis System: a single-centre study on 78 patients with acute urinary retention and poor general health.
abstract: OBJECTIVE
  To evaluate the Targis System in men presenting with acute urinary retention, high prostate volume and high operative risk.
  
  
  METHODS
  Between August 1997 and March 2001, a total of 78 patients in poor general health status presenting with large prostate glands and acute urinary retention secondary to BPH were treated with the Targis TUMT device. Mean age, mean prostate volume, and the percentage of patients who were able to urinate spontaneously after the procedure as well as mean peak and average flow rates and mean residual urine volume were evaluated.
  
  
  RESULTS
  68 (87.1%) of the 78 patients were able to urinate spontaneously three months after the procedure. In 5 (7.3%) of the 68 patients urinary retention recurred within two years. Following treatment, the mean peak flow rate in the 68 successfully treated patients was 11.1 ml/s, while the mean postvoid residual volume was 46 ml.
  
  
  CONCLUSIONS
  Based on these data we recommend transurethral thermotherapy using the Targis System for patients in poor general health presenting with urinary retention and prostate volumes of more than 35 cc in whom TURP is not possible.
