Actos Bladder Cancer : Radical cystectomy is one of the biggest and most complex procedures performed by urologists. In addition to its complexity from a technical standpoint, you will likely have many questions not only related to cancer control but also to quality of life after surgery. Cystectomy can affect your quality of life from both an emotional and physical standpoint. After surgery, you may face specific physical adjustments to die urinary diversion, possible changes in sexual function, and changes in bowel habits and function. Specific side effects and complications related to cystectomy and urinary diversion are discussed in Chapter 4. An essential aspect to enhanced quality of life after surgery is to be proactive in the decision-making process before surgery. Ask your surgeon many questions before surgery, because knowing what to expect after surgery will ease this transition. A cancer diagnosis is a difficult time for anyone, and thoughts and questions will race through your head faster than you can remember them. Write them down as you think of them, so you can have a complete discussion at the time of consultation with your physician.
As stated previously this is a big surgery, and your surgeon may have you see other specialists before your procedure to ensure you are in the best medical condition to undergo surgery. You may be admitted to the hospital the day before your scheduled surgery for any remaining tests and to prepare your bowel for surgery. In the last decade, however, medicine has become increasingly more outpatient based, and many surgeons have eliminated the preoperative admission and have you report to the hospital the morning of surgery. Your surgeon will most likely have you only consume clear liquid on the day before surgery to clear out your GI tract, which allows for a technically easier urinary diversion and may also decrease your risk of complications. Along this same line, most surgeons will have you do some form of bowel preparation the day or two leading up to surgery. This is also used to cleanse your GI tract before surgery.
Immediately after surgery you will generally stay in the hospital 5-10 days. Postoperative practice varies from surgeon to surgeon, but most leave a small drain in the abdomen to monitor for leakage of urine from the newly created diversion and intestinal contents from the reconnected bowel. If there is no evidence of an internal leak, the drain routinely is removed at the bedside (with minimal discomfort) before discharge from the hospital. Your surgeon may also leave a nasogastric tube in for the first day or so after surgery. This is a tube that goes from your nose to your stomach and keeps your stomach decompressed, which prevents abdominal bloating and vomiting.

Generally, starting on the day after surgery you will be out of bed and with assistance from the hospital staff will start walking. It is very important to begin walking as soon as possible because it will make you feel better, will help with early return ofbowel function, and will decreasethe chances of developing blood clots in your legs and pelvic veins. You will also be instructed on breathing exercises while in bed and sitting to help expand your lungs after surgery and to prevent pneumonia. One of the major obstacles before discharge is return ofbowel function and resumption of a regular diet. Your GI tract can be slow to return to normal function, largely related to the bowel work required for the urinary diversion. This will take time, and it is important to not force your diet too soon after surgery because this will increase your chances of nausea and vomiting. In general, your body will tell you when you are ready to eat.
Use your time in the hospital to learn as much as you can about your urinary diversion. Most centers in which cystectomies are performed have an enterostomal therapist with expertise in taking care of patients with urinary diversions. If you have a new ileal conduit, they will go over the general maintenance of the abdominal stoma and urinary appliance bags. This will make you more comfortable and confident in dealing with your diversion at the time of discharge from the hospital. Upon discharge from the hospital, your surgeon will give you precise instructions regarding physical activity, exercise, and resumption of sexual intercourse. It is important to follow these instructions carefully to ensure a smooth postoperative recovery.
If you underwent a continent urinary diversion, you will likely be discharged from the hospital with a catheter in the newly created reservoir to temporarily drain the urine until the reservoir is completely healed. If you have a cutaneous catheterizable diversion, a catheter is left in the catheteriz- able channel and a separate catheter is often brought out through a separate incision in the abdominal wall. These are temporary and generally removed 2 to 3 weeks after surgery. If you have an orthotopic diversion, a Foley catheter is generally placed in the diversion through your urethra. It is extremely important that you are careful with these tubes at home because dislodgement requires replacement and occasionally can lead to damage of your newly constructed leservoir. Mucus is often secreted from the bowel used to create your new urinary reservoir, and the nurses in the hospital will teach you how to flush your tubes with sterile saline before discharge to avoid mucous obstruction, which can lead to inadequate drainage.

Occasionally, a portion of the bladder involved with tumor can be removed while sparing the remainder of the bladder. In selected patients this allows for preservation of normal bladder function and continence and decreased complications because no urinary diversion is required. Unfortunately, only a small percentage of individuals will be candidates for such an approach—generally, patients with smaller, solitary tumors on the dome of the bladder. Individuals with multifocal tumors, large tumor, or carcinoma in situ are not candidates for this procedure. Recovery time for a partial cystectomy is generally quicker tiian that of a radical cystectomy, and hospital times tend to be shorter. A Foley catheter is left in place for 7-10 days to allow the bladder time to heal.
The basic function of the bladder is to store urine. By directly instilling medications into the bladder, physicians have capitalized on this property of the bladder. By placing these agents into the bladder, these agents come into direct contact with the cancer cells. Intravesical (within the bladder) therapy is often used for patients with non-muscle-invasive bladder cancer. It can be used immediately after TURBT, as a single dose, to prevent recurrence of noninvasive tumors and is also used in the form of weekly outpatient administrations (usually 6 weeks at a time) to prevent both the recurrence and progression of bladder cancer.
The two basic agents that are used as intravesical therapies are chemotherapy drugs and immunotherapy agents. The most commonly used therapy in the United States is bacillus Calmette-Guerin (B CG), which is a form of immunotherapy. BCG is actually a vaccine that was originally developed for protection from tuberculosis. In the 1970s and early 1980s, it was noted to have intravesical effectiveness for the treatment of non-muscle-invasive bladder cancer. Although the exact mechanism of BCG activity is unknown, it works through local stimulation of the immune system. A Foley catheter is placed in the bladder, and then BCG is administered through the catheter into the bladder for 1 to 2 hours. Traditionally, BCG has been given once a week for 6 weeks to patients with high-grade non-muscle- invasive bladder cancer or to those patients with carcinoma in situ. Some studies have shown that routine maintenance instillations in addition to die traditional 6-week course may be more effective in preventing disease recurrence. BCG has proven not only to prevent recurrence of bladder cancer, but also to prevent progression to muscle-invasive disease and therefore is the first-line intravesical agent used in the United States.
