Transrectal hyperthermia, transurethral thermotherapy, prostatic stent
, and prostatic spiral were used to treat 120 poor operative risk pati
ents with symptomatic benign prostatic hyperplasia. The preoperative s
ubjective and objective conditions of the four groups (each of 30 pati
ents) were comparable. None of the patients had an indwelling catheter
, but according to flow nomograms, all were obstructed. The greatest i
ncrease in peak flow rate was observed after stent placement, while th
e greatest decease of residual urine volume was seen after the inserti
on of the stent and transrectal hyperthermia. According to maximum flo
w nomograms, only the placement of the stent resolved bladder outlet o
bstruction. The greatest improvement in subjective symptoms was the re
sult of stent insertion, but the heating procedures also caused a sign
ificant reduction of symptom scores. The spiral produced satisfactory
results only in the short term. (C) 1994 Wiley-Liss, Inc.
