Bladder Cancer and Urostomy

Bladder cancer is among the most common urological cancers in the United Kingdom, with approximately 10,000 new cases diagnosed each year. When the disease invades the muscle wall of the bladder, or when less invasive treatments fail to control it, surgical removal of the bladder — radical cystectomy — becomes necessary. Because the bladder stores and expels urine, its removal requires an alternative route for urinary drainage: a urostomy. Understanding the relationship between bladder cancer, cystectomy, and urinary diversion helps patients, carers, and healthcare students navigate one of the most significant decisions in cancer treatment.

What Is a Urostomy?

A urostomy is a surgically created opening (stoma) on the abdominal wall through which urine passes continuously into a collecting pouch worn externally. Unlike the bladder, there is no voluntary control over urine flow, so a drainable pouch is worn at all times and emptied several times a day. At night, the pouch connects to a larger bedside drainage bag.

Urostomies differ from colostomies and ileostomies in one important respect: they drain urine rather than stool, and the output is therefore liquid and continuous. The stoma itself is typically located on the right lower abdomen, though placement is planned individually by the surgical team and stoma care nurse before the operation.

When Is a Urostomy Needed in Bladder Cancer?

Muscle-Invasive Bladder Cancer

Bladder cancer is staged according to how deeply it penetrates the bladder wall. Non-muscle-invasive disease (stages Ta, T1, and carcinoma in situ) is generally managed with endoscopic surgery and intravesical immunotherapy or chemotherapy. When cancer reaches or breaches the muscular layer (stage T2 and above), the standard curative intent treatment is radical cystectomy: surgical removal of the bladder, nearby lymph nodes, and, in women, often the uterus and part of the vagina; in men, the prostate and seminal vesicles are typically removed as well.

High-Risk Non-Muscle-Invasive Disease

A minority of patients with high-grade, recurrent, or BCG-unresponsive non-muscle-invasive bladder cancer are also offered radical cystectomy because of the significant risk of progression to muscle invasion.

Other Indications

In rare cases, severe radiation cystitis, bladder dysfunction, or other pelvic malignancies eroding the bladder may necessitate urinary diversion with or without cystectomy.

Types of Urinary Diversion

Once the bladder is removed, three broad categories of urinary diversion can be constructed. The most appropriate choice depends on the patient’s age, fitness, cancer extent, renal function, and personal preference.

Ileal Conduit (Incontinent Diversion)

The ileal conduit is the most commonly performed urinary diversion globally. The surgeon isolates a short segment (approximately 15–20 cm) of the terminal ileum, disconnects it from the bowel without disturbing blood supply, and sews the two ureters into one end. The other end is brought through the abdominal wall to form the urostomy stoma. Urine drains freely and continuously into the external pouch. The remaining bowel is rejoined and normal gut function resumes.

The ileal conduit is durable, technically well established, and associated with predictable long-term outcomes. It remains the reference standard against which other diversions are compared.

Continent Cutaneous Diversion

In this approach, a reservoir (pouch) is constructed internally from a larger segment of bowel and connects to a small, flush stoma on the abdomen. The patient does not wear an external pouch continuously but instead self-catheterises the reservoir several times a day to empty it. This option suits highly motivated, physically dexterous patients and requires careful ongoing surveillance. It carries a higher risk of early and late complications than an ileal conduit.

Orthotopic Neobladder

A neobladder (also called orthotopic reconstruction) uses a bowel segment to create an internal reservoir that is connected directly to the urethra, allowing voiding through the urethra rather than through a stoma. There is no external pouch. However, urinary continence — particularly at night — is incomplete in many patients, and self-catheterisation may still be required. A neobladder is not suitable for patients with tumour involvement of the urethra or those with certain anatomical or functional contraindications.

Surgery, Recovery, and the Role of the Stoma Care Nurse

Radical cystectomy with urinary diversion is a major abdominal operation usually lasting four to eight hours. It may be performed as open surgery or, increasingly, via minimally invasive (laparoscopic or robotic-assisted) approaches. Hospital admission typically lasts seven to fourteen days, with full recovery taking six to twelve weeks.

Pre-operative stoma siting — the process of marking the ideal stoma position on the abdomen before surgery — is a critical step. A specialist stoma care nurse (also called a WOC or ET nurse) carries out this assessment with the patient standing, sitting, and lying down to find a site that avoids skin folds, scars, and the belt line. Good siting dramatically reduces pouching difficulties and skin problems post-operatively.

Post-operatively, the stoma care nurse teaches the patient how to empty and change the pouch system, manage urine output overnight, care for the peristomal skin, and recognise early complications.

Living Well With a Urostomy After Bladder Cancer

Physical Wellbeing

Most people return to employment, exercise, travel, and leisure activities within a few months of surgery. Swimming is generally possible with a well-fitted, waterproof pouch. A high fluid intake — typically 1.5 to 2 litres daily unless otherwise advised — helps maintain urine flow and reduces the risk of urinary tract infection, to which urostomy patients have some increased susceptibility.

Skin Care

Peristomal skin problems — irritation, leakage-related dermatitis, and folliculitis — are among the most common complications and are largely preventable with correct pouch application technique and prompt attention when leaks occur. The stoma care nurse is the primary resource for troubleshooting skin concerns.

Psychological and Sexual Wellbeing

A cancer diagnosis combined with significant bodily change can affect self-image, mood, and intimate relationships. Anxiety, depression, and concerns about sexuality are common and legitimate responses. Psychological support, peer support groups, and, where appropriate, specialist psychosexual counselling are all recommended components of holistic care. Research indicates that pre-operative counselling and access to specialist nursing support are associated with better psychological adjustment and quality of life.

Oncological Follow-Up

A urostomy does not in itself require oncological monitoring, but bladder cancer surveillance after cystectomy does. This typically involves regular CT imaging, blood tests, and clinical review to detect recurrence early. Patients should maintain their scheduled follow-up appointments.

Potential Complications

Complications associated with urostomy and urinary diversion include:

• Stomal complications: retraction, prolapse, stenosis, parastomal hernia
• Peristomal skin irritation from urinary leakage
• Urinary tract infection (more common than in people with an intact bladder)
• Uretero-ileal anastomosis stricture (narrowing where the ureter joins the conduit)
• Renal deterioration over time, particularly if reflux is present or infections recur
• Vitamin B12 deficiency (if a large ileal segment was used), requiring monitoring and supplementation

Regular follow-up with the urology and stoma care team enables early detection and management of these issues.

The Bottom Line

A urostomy following radical cystectomy for bladder cancer represents a life-altering but manageable change. The ileal conduit remains the most commonly performed and well-evidenced form of urinary diversion, though continent alternatives exist for carefully selected patients. With thorough pre-operative preparation, skilled stoma siting, and ongoing specialist nursing support, most people adapt successfully and report acceptable quality of life. Always consult your stoma care nurse, urologist, or specialist oncology team for guidance tailored to your individual circumstances — no written resource can substitute for personalised clinical care.
