Neocystis in women
An orthotopic reservoir in women is possible in the absence of a tumor in the bladder neck and urethra (checked by urgent histology) and preservation of the supporting structures of the urethra; the vagina is restored, if necessary, with strengthening of the posterior wall to prevent hypermobility of the reservoir. Daytime retention is achieved in 80–90%, night retention in 60–70%; Some patients require periodic self-catheterization. If neocystis is not possible, a conduit with a urostomy is formed. The laparotomy approach is chosen for common tumors and complex anatomy. Recovery 2–3 months.
When is the bladder removed?
- muscle-invasive bladder cancer (T2–T4a) without distant metastases is the mainstay of cure, often after neoadjuvant chemotherapy;
- high-risk non-invasive cancer that recurs after BCG therapy, carcinoma in situ that does not respond to treatment;
- extensive tumors that cannot be removed endoscopically, intractable bleeding;
- tumors of neighboring organs with germination into the bladder (cancer of the cervix, rectum - with the appropriate specialists).
Urine diversion options
After the bladder is removed, the urine needs a new path. Ureterocutaneostomy - the ureters are exposed to the skin of the abdomen with urostomy bags; the fastest and most gentle option for weakened patients. Bricker conduit - a segment of the ileum connects the ureters to one stoma on the abdomen (reliable, standard). Orthotopic reservoir (neocystis) - a new bladder is formed from 50–60 cm of intestine, sewn to the urethra: the patient urinates naturally, without a stoma, with a preserved urethra and the absence of a tumor in it. The choice depends on the stage, age, renal function and wishes of the patient.
Recovery and life after
The operation is large: 10–14 days in the hospital, 2–3 months of recovery, training in stoma care or neocystis training (urination by the hour, bedwetting in the first months). The intestinal reservoir requires monitoring of electrolytes and vitamin B12. Five-year survival rate for a localized tumor is 60–80%, for lymph node involvement — 30–40%; observation with MSCT every 3–6 months.
