Kg. Stravodimos et al., TRANSURETHRAL MICROWAVE THERMOTHERAPY FOR MANAGEMENT OF BENIGN PROSTATIC HYPERPLASIA - A SINGLE-INSTITUTION EXPERIENCE, Urology, 51(6), 1998, pp. 1008-1012
Objectives. This is the first and largest single institution retrospec
tive study in the United States to examine the effects of transurethra
l microwave thermotherapy (TUMT) for the treatment of benign prostatic
hyperplasia (BPH). Methods. From September 1996 to June 1997, 78 men
with moderate to severe symptomatic BPH were treated with the Prostatr
on at our institution, Patient age ranged from 52 to 85 years. Prostat
e volume ranged from 25 to 110 cc, and mean total energy applied durin
g the treatment was 156.17 kJ. Patients were re-evaluated at 3 months
and were asked to answer a questionnaire regarding their opinion about
the treatment. Results. At 3 months there was a significant decrease
in mean symptom score from 19.6 to 11.2 (P <0.0001). Mean peak flow ra
te increased from 8.5 to 12.8 mL/s (P <0.0001). Mean postvoid residual
urine decreased from 56.8 to 22.0 mL (P <0.0001). We did not observe
any severe complications. Unlike prior studies, we removed the Foley c
atheter, and patients performed clean intermittent catheterization (CI
C) when necessary. There was no significant differences in subjective
and objective parameters between these patients and those who did not
need CIC. Patient opinion about the treatment was not affected by CIC.
About two thirds (67.2%) of the patients in the study group were sati
sfied with the results of treatment, and 60.3% would undergo the same
procedure again. Conclusions. TUMT of the prostate is an effective, sa
fe, and acceptable form of treatment for patients with BPH. Longer fol
low-up is needed to examine the durability of TUMT treatment. (C) 1998
