Abstract: | A new way of applying transurethral ultrasound scanning in the common surgical procedure of the transurethral resection of
the prostate is described. The scanning is incorporated as part of a robotic procedure for surgery, so that the overall time
spent in an operation can be further shortened, and a safe and accurate operation can be achieved. The prostate dimensions
obtained pre-operatively by the transrectal method and those obtained operatively are compared. A robotic system, which was
developed specifically to remove prostatic adenoma automatically, is discussed. The system, called a motorised frame, is briefly
described, together with its predecessor, a manual frame, in relation to ultrasound measurements. Sizing of the prostate pre-operatively
using transrectal ultrasound methods is discussed, using both the manual and the motorised frame. The shortcomins of transrectal
ultrasound for use in a robotic procedure are highlighted. |
