title: A comparison of transrectal hyperthermia, transurethral thermotherapy, urolume wallstent, and prostatic spiral for benign prostatic hyperplasia patients at poor operative risk.
abstract: Transrectal hyperthermia, transurethral thermotherapy, prostatic stent, and prostatic spiral were used to treat 120 poor operative risk patients with symptomatic benign prostatic hyperplasia. The preoperative subjective and objective conditions of the four groups (each of 30 patients) were comparable. None of the patients had an indwelling catheter, but according to flow nomograms, all were obstructed. The greatest increase in peak flow rate was observed after stent placement, while the greatest decrease of residual urine volume was seen after the insertion of the stent and transrectal hyperthermia. According to maximum flow nomograms, only the placement of the stent resolved bladder outlet obstruction. The greatest improvement in subjective symptoms was the result of stent insertion, but the heating procedures also caused a significant reduction of symptom scores. The spiral produced satisfactory results only in the short term.
