FIG. 3.

The simple prostatectomy model using a clementine as modified to be fixed on foam or cardboard and to have a urethra. A party balloon is inserted into the centre of the fruit (A) as the urethra and is later tied to the foam board. The urethra can be stretched as in real cases (B) before being formally incised. The blue suture fixing the base of the prostate model to the foam board (A and C) acts as a bleeding vessel to oversew when the pulp (adenoma) has been removed (in this case the skin [capsule] is split to demonstrate fixation to the foam board).
