Urinary diversion surgery is a surgical procedure used to reconstruct the urinary tract, primarily for patients who have lost bladder function due to disease or trauma. This treatment involves creating an alternative urinary pathway using artificial or autologous tissue, enabling patients to effectively excrete urine and prevent renal impairment or urinary retention. The surgery is suitable for conditions such as end-stage bladder disease, severe urethral obstruction, or post-cystectomy for bladder cancer, with the goal of restoring basic physiological functions and improving quality of life.
Depending on patient needs and severity of the condition, urinary diversion surgery can be divided into three main types:
1. Ileal Conduit: A segment of the small intestine is modified to form a urine collection conduit, with the end connected to the abdominal wall to drain urine into an external collection bag.
2. Continent Diversion: Utilizes a segment of the intestine to construct an internal reservoir, allowing the patient to drain urine via percutaneous puncture, avoiding dependence on external urinary bags.
3. Neobladder: Reconstructs a new bladder using intestinal tissue, connected to the urethra, mimicking normal urination, but requires training for urination control.
This surgery is mainly indicated for the following conditions:
The procedure is performed under general anesthesia, with operative time depending on the type of diversion, typically lasting 4-8 hours. Postoperative hospitalization lasts 7-14 days for wound care and functional training. Postoperative care includes:
The main benefits of this treatment include:
Possible complications include:
Preoperative assessment should include renal function and cardiopulmonary status. Contraindications include:
This surgery is often combined with the following treatments:
According to a 2019 urology medical yearbook study, the 5-year survival rate and renal function preservation rate for neobladder patients reached 83%, while continent diversion reduced skin irritation risks by 30%. Long-term follow-up shows that 70% of patients can adapt to external urinary collection devices, but ongoing monitoring of intestinal and renal function is necessary.
For patients unable to undergo surgery, alternatives include:
Preoperative assessments typically include detailed urological examinations and adjustment of chronic disease medications based on health status. A low-residue diet may be recommended 3 days prior to surgery to reduce bowel contents, and anticoagulant medications should be temporarily discontinued as per medical advice to minimize bleeding risk. The nursing team will provide instructions on personal hygiene preparations, such as cleaning the surgical site.
How long does it take to recover urination function after surgery? What activities should be avoided in daily life?Initially, due to the adaptation period of the stoma or neobladder, patients may need to use collection devices or perform regular irrigation. Recovery of urination function typically takes several weeks to months, with pelvic floor muscle training guided by physical therapists. During the first three months post-surgery, patients should avoid heavy lifting, strenuous bending, and prolonged standing to prevent pressure on sutures.
Which long-term complications require immediate medical attention? How can infection risks be minimized?If symptoms such as high fever, redness, swelling, warmth, pain at the drainage site, abnormal bleeding, or urine leakage occur, patients should seek medical care within 24 hours. Daily cleaning of the skin around the stoma, using medical leak-proof ointments, and regular rinsing of the collection system with antibiotic solutions are recommended. Patients with compromised immune function should have more frequent follow-ups.
What dietary adjustments are needed after surgery? Which foods may increase complication risks?Increasing intake of high-fiber vegetables and whole grains is advised to prevent constipation and excessive abdominal pressure. Spicy, high-sugar, and processed foods should be minimized to avoid irritating the urinary tract or promoting infection. For ileal conduit or neobladder procedures, a low-protein diet may be recommended initially to reduce ammonia production, gradually transitioning to a normal diet later.
What is the approximate improvement rate in quality of life after surgery? What factors influence long-term outcomes?Studies indicate that approximately 70-80% of patients regain basic daily activities within one year post-surgery, but precise control of urination may require a longer adaptation period. The success rate is influenced by the severity of the primary disease, choice of surgical method, and patient adherence to postoperative care. Regular monitoring of renal function and urinary imaging can detect complications early and improve long-term results.
