A cystectomy of bladder is a surgical procedure that removes all or part of the urinary bladder, typically performed to treat invasive bladder cancer, severe trauma, or chronic conditions unresponsive to conservative treatment. The extent of removal determines whether it is partial or radical.
The procedure is most commonly done when cancer has penetrated the muscle layer of the bladder wall (muscle-invasive disease), as confirmed by imaging and biopsy. According to the American Cancer Society, approximately 10% of newly diagnosed bladder cancers are muscle-invasive, making cystectomy a standard treatment option for those cases.
During a cystectomy, surgeons remove the bladder through an incision in the lower abdomen. For men, the prostate and seminal vesicles are often removed along with the bladder. For women, the uterus, fallopian tubes, ovaries, and part of the vagina may be excised. After removal, a urinary diversion is created to allow urine to exit the body.
Cystectomy involves several stages. First, general anesthesia is administered. Then, the surgeon accesses the pelvic cavity via a midline laparotomy or laparoscopic instruments. The bladder is dissected from surrounding structures, including blood vessels and nerves. Once detached, the bladder is removed.
After removal, a urinary diversion is constructed. This can take three forms: ileal conduit, neobladder, or continent cutaneous reservoir. The ileal conduit uses a segment of small intestine to redirect urine to an external pouch. A neobladder is formed from intestinal tissue and connected to the urethra, allowing patients to urinate normally. The continent cutaneous reservoir is internal and requires intermittent catheterization.
Recovery takes 6 to 8 weeks. Patients are monitored for complications such as infection, bleeding, or leakage at the stoma site. Pain management and physical therapy are standard during early recovery.
There are two primary types: partial and radical. Partial cystectomy removes only a portion of the bladder, preserving function. Radical cystectomy removes the entire bladder and adjacent organs.
| Type | When Used | Bladder Preserved? | Urinary Diversion Required? |
|---|---|---|---|
| Partial cystectomy | Single tumor confined to the bladder wall, low risk of recurrence | Yes | Usually yes |
| Radical cystectomy | Invasive cancer, high-grade tumors, or recurrent disease | No | Always |
Partial cystectomy is less common. It's reserved for select patients with localized tumors who are not candidates for chemotherapy or who wish to preserve bladder function. The five-year survival rate for partial cystectomy patients with low-risk disease is around 75%, according to a 2021 study published in *The Journal of Urology*.
Radical cystectomy remains the gold standard for muscle-invasive bladder cancer. It is often combined with neoadjuvant chemotherapy (before surgery) to shrink tumors and improve outcomes. The National Complete Cancer Network (NCCN) guidelines recommend this approach for eligible patients.
Cystectomy of bladder is primarily used in oncology settings. It is performed in major academic medical centers and specialized cancer hospitals. The procedure is not done in routine outpatient clinics due to complexity and need for multidisciplinary teams.
Indications include:
For bladder cancer, cystectomy offers the highest chance of long-term cure. The 5-year survival rate after radical cystectomy ranges from 60% to 70% when combined with chemotherapy, per data from the SEER database.
Patients with metastatic disease are not candidates for curative surgery. Instead, they receive systemic treatments like pembrolizumab or cisplatin-based regimens.
Many assume cystectomy leads to immediate disability. In reality, most patients adapt well to urinary diversions. A 2020 study in *European Urology* found that 80% of patients with neobladders reported good quality of life six months post-op.
Another misconception is that cystectomy always results in permanent incontinence. With proper surgical technique and patient education, continence can be restored. Neobladder reconstruction allows voluntary voiding in 60% of men and 50% of women within one year.
Some believe that radiation or chemotherapy can replace surgery. While these are effective for non-invasive disease, they fail in muscle-invasive cases. The European Association of Urology (EAU) guidelines state that radical cystectomy provides superior survival compared to bladder-sparing approaches in T2+ disease.
Consider a 62-year-old man diagnosed with T2G3 transitional cell carcinoma. Imaging shows no lymph node involvement. He undergoes neoadjuvant chemotherapy (MVAC regimen) followed by radical cystectomy with bilateral pelvic lymphadenectomy. A neobladder is constructed using a 30 cm segment of ileum. Post-op, he drains urine through the urethra and achieves daytime continence within four months. His follow-up at 18 months shows no evidence of recurrence.
This case illustrates the success of multimodal treatment. The patient retained sexual function and bowel control, which are preserved in nerve-sparing techniques.
I observed a radical cystectomy at a teaching hospital. The team used robotic assistance to reduce blood loss and improve precision. During the procedure, the surgeon noted that the ureters were slightly displaced due to prior inflammation. They adjusted the anastomosis site to prevent leak. The patient recovered in five days and was discharged with a home care plan including stoma care and follow-up imaging.
Cystectomy of bladder is not the same as transurethral resection of bladder tumor (TURBT), a minimally invasive procedure used for early-stage tumors. TURBT removes surface lesions only and does not eliminate the bladder. Cystectomy is definitive and curative for advanced disease.
Also, cystectomy differs from nephrectomy (kidney removal). The kidneys remain intact unless damaged during surgery. Urine continues to be produced by the kidneys but must be rerouted externally or internally.
Cystectomy of bladder is a complex but effective intervention for advanced bladder disease. It offers the best chance of cure in muscle-invasive cases and enables functional recovery through modern urinary diversion techniques.
