Urinary Diversion Surgery in Singapore | Bladder Cancer Treatment

If you or a loved one has been diagnosed with bladder cancer or other conditions requiring bladder removal, understanding your urinary diversion options is a crucial step in your treatment journey. Urinary diversion surgery creates a new way for urine to leave your body after bladder removal, helping you maintain quality of life whilst treating serious bladder conditions. Our MOH-accredited urologists in Singapore specialise in various urinary diversion techniques, providing personalised surgical solutions tailored to each patient’s medical needs and lifestyle preferences.

Urinary diversion surgery is a reconstructive procedure performed after cystectomy (bladder removal) to create an alternative route for urine to exit the body. This surgery becomes necessary when the bladder must be removed due to muscle-invasive bladder cancer, severe bladder dysfunction, or other serious conditions affecting bladder function. The procedure involves using a section of intestine to create either a new bladder substitute or an external collection system.

During urinary diversion surgery, surgeons redirect the ureters (tubes carrying urine from the kidneys) to connect with a newly created urinary pathway. The type of diversion created depends on various factors including cancer staging, patient health status, and personal preferences. Consulting a bladder specialist in Singapore helps determine the most suitable diversion method based on individual needs. Modern surgical techniques allow for multiple reconstruction options, each designed to restore urinary function whilst maintaining quality of life.

The surgery is typically performed as part of radical cystectomy for bladder cancer treatment, though it may also be indicated for severe radiation damage, neurogenic bladder, or intractable incontinence.

Ideal Candidates

• Patients with muscle-invasive bladder cancer requiring cystectomy
• Individuals with high-grade, recurrent non-muscle invasive bladder cancer
• Those with bladder dysfunction from radiation therapy or chemotherapy
• Patients with severe interstitial cystitis unresponsive to other treatments
• Individuals with neurogenic bladder causing kidney damage
• Good overall health status to undergo major surgery
• Adequate kidney function (creatinine clearance >60 mL/min)
• Sufficient intestinal length for reconstruction
• Motivation to learn new bladder management techniques

Contraindications

• Severe kidney disease or renal failure
• Extensive intestinal disease (Crohn’s disease, ulcerative colitis)
• Previous extensive abdominal radiation affecting intestines
• Severe cognitive impairment preventing self-care
• Limited life expectancy due to metastatic disease
• Uncorrectable bleeding disorders
• Active inflammatory bowel disease in areas needed for diversion

The decision for urinary diversion requires careful evaluation by an experienced urologist. Your surgeon will assess your overall health, cancer status, bowel function, and personal preferences to determine the most appropriate type of urinary diversion for your situation.

Ileal Conduit (Bricker Procedure)

The ileal conduit is the most commonly performed urinary diversion, involving creation of a urostomy using a segment of small intestine (ileum). In this procedure, a 15-20cm section of ileum is isolated whilst maintaining its blood supply. The ureters are connected to one end of this intestinal segment, whilst the other end is brought through the abdominal wall to create a stoma. Urine flows continuously from the kidneys through the conduit into an external collection bag. This technique is preferred for its reliability, shorter operative time, and lower complication rates.

Orthotopic Neobladder

An orthotopic neobladder involves creating a new bladder from intestinal tissue and connecting it to the urethra, allowing for near-normal urination. Surgeons use 40-60cm of intestine (usually ileum) to construct a spherical reservoir that stores urine. The ureters are connected to this new bladder, which is then attached to the preserved urethra. Patients learn to empty the neobladder by relaxing pelvic muscles and increasing abdominal pressure. This option is suitable for younger, motivated patients with good kidney function and no cancer at the urethra.

Continent Cutaneous Diversion

This technique creates an internal reservoir from intestinal segments with a catheterisable channel to the skin surface. Unlike an ileal conduit, no external bag is needed as the reservoir stores urine internally. Patients empty the pouch several times daily by inserting a catheter through a small, concealed stoma. Various techniques exist including Indiana pouch (using colon and ileum) and Miami pouch variations. This option suits patients desiring continence without the demands of a neobladder.

Technology & Equipment Used

Modern urinary diversion surgery utilises established surgical technologies including high-resolution laparoscopic systems for minimally invasive approaches, surgical staplers for precise intestinal reconstruction, and intraoperative navigation systems for complex cases. Robotic-assisted surgery may be employed for enhanced precision during reconstruction.

Pre-Treatment Preparation

Before urinary diversion surgery, you’ll undergo comprehensive evaluation including blood tests, kidney function studies, and imaging scans to assess cancer extent. Bowel preparation begins 2-3 days before surgery with a clear liquid diet and prescribed laxatives to clean the intestines. You’ll meet with a stoma nurse to discuss post-surgical care and mark optimal stoma placement if applicable. Antibiotics are administered before surgery to prevent infection. Nutritional optimisation may be recommended to improve healing. You’ll stop certain medications like blood thinners as directed by your surgeon.

During the Procedure

Urinary diversion surgery is performed under general anaesthesia and typically takes 4-7 hours depending on the technique chosen. After making an abdominal incision (or several small incisions for laparoscopic approach), the surgeon removes the bladder and surrounding lymph nodes if treating cancer. The selected intestinal segment is then isolated and reconfigured according to the planned diversion type. Ureters are carefully connected to the new urinary pathway with attention to preserving blood supply. For neobladder creation, the intestinal segment is shaped into a spherical reservoir. The surgery concludes with placement of drainage tubes and catheters.

Immediate Post-Treatment

Following surgery, you’ll recover in a monitored setting where vital signs and urine output are closely observed. Pain management includes epidural analgesia or patient-controlled pain pumps. Multiple tubes and drains remain in place temporarily, including ureteral stents, wound drains, and a nasogastric tube. You’ll begin breathing exercises and leg movements to prevent complications. The surgical team monitors for signs of infection, bleeding, or anastomotic issues. Initial recovery focuses on stabilising vital functions whilst beginning the healing process.

First 24-48 Hours

During the initial recovery period, you’ll remain on intravenous fluids and pain medications while bowel function returns. The nasogastric tube helps prevent nausea and abdominal distension. Nurses monitor urine output through catheters and stents to ensure proper drainage from both kidneys. Early mobilisation begins with sitting up and short walks to prevent blood clots and pneumonia. Respiratory therapy helps clear the lungs and prevent complications. Stoma care education begins if you have an ileal conduit, guided by your team at a urology clinic in Singapore.

First Week

As bowel function returns, typically by day 3-5, you’ll gradually resume oral intake starting with clear liquids. Drainage tubes are removed as output decreases. Physical therapy intensifies with longer walks and stair climbing. For ileal conduit patients, hands-on stoma care training begins. Neobladder patients learn initial bladder training techniques. Pain transitions from intravenous to oral medications. Most patients are discharged home by day 5-10 with detailed care instructions.

Long-term Recovery

Complete recovery takes 6-12 weeks, during which you’ll gradually increase activity levels whilst avoiding heavy lifting. Follow-up appointments monitor healing and kidney function through blood tests and imaging. Ileal conduit patients master independent stoma care and pouching techniques. Neobladder patients undergo progressive bladder training to achieve continence, which may take 3-6 months. Regular surveillance for cancer recurrence begins with cystoscopy and CT scans. Long-term monitoring includes annual kidney function tests and metabolic evaluations.

Urinary diversion surgery offers life-saving treatment for bladder cancer whilst preserving kidney function and enabling continued quality of life. For cancer patients, the procedure allows complete removal of diseased tissue whilst maintaining urinary drainage. The surgery prevents dangerous urine backup that could damage kidneys and cause life-threatening complications.

Patients experience relief from painful bladder conditions and regain control over their health situation. Modern diversion techniques provide multiple options to match individual lifestyles, from the simplicity of ileal conduits to the near-normal function of neobladders. Many patients successfully return to work, travel, and recreational activities after recovery. The surgery eliminates chronic pain, bleeding, and infection risks associated with diseased bladders. Social continence achieved through various diversion types helps maintain dignity and independence. With proper care and follow-up, urinary diversions function effectively for decades, allowing patients to lead fulfilling lives despite their initial diagnosis.

Common Side Effects

Most patients experience temporary bowel dysfunction lasting 3-7 days post-surgery, managed with medications and dietary modifications. Mild metabolic changes occur as intestine adapts to handling urine, requiring periodic monitoring and electrolyte supplementation. Mucus production from intestinal segments is normal and managed with increased fluid intake and irrigation. Temporary urinary leakage affects 20-30% of neobladder patients during the training period. Stoma irritation in ileal conduit patients typically resolves with proper fitting and skin care products.

Rare Complications

Serious complications occur in less than 5% of cases but may include anastomotic leak requiring surgical repair, deep vein thrombosis despite preventive measures, or wound infection needing antibiotic treatment. Long-term risks include kidney stone formation (10-15% over 10 years), stomal stenosis requiring revision, or metabolic acidosis in patients with compromised kidney function. Neobladder rupture is extremely rare but requires emergency surgery.

Our experienced urological surgeons employ meticulous surgical technique and comprehensive perioperative protocols to minimise complication risks. Regular follow-up allows early detection and management of any developing issues.

The cost of urinary diversion surgery varies based on the specific technique chosen, with more complex reconstructions like neobladders requiring longer operative time and hospitalisation. Factors affecting total cost include pre-surgical evaluations, surgeon and anaesthetist fees, hospital stay duration, and post-operative supplies. The surgical fee typically covers the complete reconstruction procedure, intraoperative monitoring, and immediate post-surgical care.

Long-term costs should also be considered, including stoma supplies for ileal conduit patients, regular follow-up appointments, and surveillance imaging. Whilst the initial investment is significant, the procedure’s life-saving nature and quality of life improvements provide substantial value.
