A retrospective self-audit exercise was undertaken on 47 men who under
went transurethral resection of the prostate and in whom the resected
weight was 80 g or more. The operative mortality and morbidity rates w
ere 6 and 55% respectively, being highest in the ''very old and unfit'
' group (22 and 88%). The complication rate increased if the resected
prostatic weight was 100 g or more, or if the resection time exceeded
75 min. It was concluded that careful selection of patients is necessa
ry before undertaking TUR for a large gland.
