a. Spontaneous release of urine might contaminate the sterile field.
b. An empty bladder provides more room in the pelvis.
c. A sterile urine specimen is needed preoperatively.
d. A Foley catheter prevents the membranes from spontaneously rupturing.

Catheterization provides room for the application of the forceps blades and limits bladder trauma.
