Final answer:
A radical cystoprostatectomy, not commonly performed for prostate cancer alone, involves making an incision into the bladder to remove both the bladder and prostate en bloc.
Step-by-step explanation:
The prostatectomy procedure that involves an incision into the bladder to remove the prostate en bloc is known as a radical cystoprostatectomy. This surgical technique is typically performed in cases of invasive bladder cancer that also involves the prostate, rather than being a standard treatment for prostate cancer alone. During this procedure, the entire bladder and the prostate gland are removed, and urinary diversion is created. The operation can be technically challenging and comes with a risk of significant side effects, including changes to urinary and sexual function.
Other types of prostatectomy include retropubic, perineal, and laparoscopic or robotic-assisted prostatectomy. The choice of procedure depends on factors such as the extent of cancer, the patient's health, and the surgeon's experience.
