Dr. Catalona's article is a good read on the subject:
"When the catheter is removed, the bladder is a shrunken version of itself.
"Over weeks and months, the bladder expands again and, most often, returns to normal size and normal function," Dr. Catalona said.
Also, when the bladder is exposed during the surgery, it takes some physical blows and it swells, just as other parts of your body swell when they take a hit.
"Frequent urination is normal after a radical prostatectomy," Dr. Catalona said. "The main cause is that the bladder wall is swollen and thickened and irritable. Normally, the bladder wall is thin and very elastic and maintains a low pressure until it has stored 8 to 10 ounces of urine. After surgery, the swollen bladder does not store much urine at a low pressure. As soon as it starts to fill, the pressure goes up and the patient feels the need to urinate. In the great majority of cases, this gradually improves with time, but it can take more than a year in some cases."
Other consequences occur too.
"You create surgical planes or in lay terms, cuts, and as those cuts heal, it's possible they create scars," Dr. Catalona said.
Later in the healing process, those scars can cause difficulties for the bladder because they make it difficult for the bladder to expand as it should. The scars increase the time it takes for the bladder to expand and therefore increase the time to return to continence."
