Ileovesicostomy
Ileovesicostomy is a form of incontinent cutaneous urinary diversion that creates a low-pressure ileal conduit ("bladder chimney") from the bladder dome to an abdominal-wall stoma — without ureteroenteric anastomosis. Popularized by Schwartz, Kennelly, McGuire, and Faerber in 1994 for patients with severe neurogenic LUTD who cannot perform CIC and have suffered chronic-catheter morbidity.[1] Its key advantage over an ileal conduit is that it preserves the native bladder and ureterovesical junctions, maintaining the physiologic antireflux mechanism and allowing potential reversibility.[2][3]
Concept and Rationale
Targets neurogenic-bladder patients who cannot perform CIC (poor hand function, immobility, body habitus, social/cognitive limitations) and have developed serious indwelling-catheter complications — urosepsis, calculi, urethrocutaneous fistulae, autonomic dysreflexia, progressive hydronephrosis.[1][4]
The procedure creates a tubularized ileal segment connecting the bladder dome to the skin for continuous low-pressure drainage into a urostomy bag. Unlike an ileal conduit, the ureters are not transected or reimplanted — they remain in their native position within the bladder wall.[2][3]
Indications
The AUA/SUFU NLUTD guideline supports ileovesicostomy in patients unable to perform self-catheterization due to poor hand function, immobility, challenging body habitus, or condom-catheter–induced skin breakdown.[5] Specific indications:
- High cervical SCI / tetraplegia — most common indication.[1][3]
- MS with progressive disability precluding CIC.[2]
- Myelomeningocele with failed prior management.[2][6]
- Complications of chronic indwelling catheter drainage.[4]
- Failed prior bladder management (sphincterotomy, augmentation, AUS).[2][7]
- Pediatric patients unable to perform reliable CIC.[6]
- Patients who are poor candidates for or refuse continent diversion or augmentation.[2]
Surgical Technique (Open, McGuire/Schwartz)[1][8][9]
- Ileal segment harvest: 15–20 cm of terminal ileum on its mesentery; bowel continuity restored.
- Proximal detubularization: the proximal 6–8 cm is opened along the antimesenteric border to create a wide funnel for the bladder anastomosis.
- Cystotomy: dome opened widely.
- Ileovesical anastomosis: detubularized proximal ileum sutured to the bladder dome in a wide funnel — critical to prevent obstruction at the ileovesical junction.
- Stoma: distal ileum remains tubularized and is brought through the abdominal wall (typically RLQ) as a flush or budded stoma.
Key principles: ileal segment functions as a conduit (not a reservoir); ureters are not touched; wide funnel anastomosis prevents mechanical obstruction.
Concomitant procedures
- Pubovaginal sling (PVS) in women with intrinsic sphincter deficiency from prolonged catheterization to achieve functional urethral closure.[8][10]
- Bladder-neck closure when the urethra is severely destroyed and a sling is insufficient — eliminates urethral leakage but renders the procedure irreversible.[11][12]
- Bladder calculus removal when stones are present.[8]
- Anticholinergic therapy continued postoperatively for persistent detrusor overactivity.[2]
Minimally invasive approaches
- Laparoscopic (Hsu 2002): 5-port transperitoneal approach; OR ~4 hr.[13]
- Robotic-assisted (Vanni/Stoffel 2009, n=8): 5-port; intracorporeal enterovesical anastomosis; extracorporeal bowel reanastomosis through stoma site. Median EBL 100 mL, OR 330 min, LOS 7.7 d; all functioning with median residual bladder volume 10 mL.[9]
- Open vs robotic (n=15): comparable OR times; trends toward lower EBL (100 vs 257 mL) and shorter LOS (8 vs 11 d). Total inpatient cost higher with robotic ($17,344 vs $14,356), driven by OR supply costs.[14]

|---|---|---|
| Poor bladder compliance | 50% | 9–17% |
| Urosepsis | 45% | Significantly reduced |
| Hydronephrosis | 21% | Resolved/stable |

| Overall complications per patient | 3.38 | 1.16 (p<0.0001) |
Urodynamic outcomes
- Stomal leak point pressure: mean 7.7 cm H₂O (Mutchnik).[3]
- Detrusor leak point pressure: 42.7 → 16.7 cm H₂O (p=0.0061, Gauthier).[8]
- Compliance improved or normalized in 83–91% (Leng).[4]
- Median residual bladder volume 10 mL postoperatively (robotic series).[9]
Advantages Over Ileal Conduit
| Feature | Ileovesicostomy | Ileal Conduit |
|---|---|---|
| Ureteroenteric anastomosis | Not required | Required (stricture risk ~7%) |
| Native antireflux mechanism | Preserved (UVJ intact) | Lost (reflux common) |
| Reversibility | Potentially reversible | Irreversible |
| Cystectomy required | No (bladder preserved) | Usually performed |
| Surgical complexity | Simpler (no ureteral dissection) | More complex |
| Long-term ureteral stricture risk | None | 7.2% |
The AUA/SUFU guideline notes that with longer follow-up, ileovesicostomy patients have an increased risk of requiring revision or alternate surgery. Ginsberg 2026 argued that ileal conduit may be the better option for the poorly compliant neurogenic bladder refractory to minimally invasive treatment, eliminating concern for elevated bladder pressures, no mucus irrigation, and demonstrated improved QoL.[5][25]
Complications
- Stomal complications — most common; 38% (Tan 2008), with mean 1.47 stomal complications per affected pt; stomal stenosis 8–13% across series.[1][2][3][11]
- Urethral incontinence — particularly in women: 27% (4/15 in Atan, all women with preoperative detrusor hyperreflexia); 1 required conversion to ileal conduit. 72% continent per urethra in Tan. Risk factors: severe preoperative detrusor hyperreflexia, intrinsic sphincter deficiency, female sex.[2][10][11]
- Ileovesical mechanical obstruction — 22% in Tan; emphasis on creating a wide funnel anastomosis was Schwartz's response.[1][11]
- Calculus formation — 33% in Atan (urinary stasis, chronic bacteriuria, mucus).[2]
- UTIs — symptomatic 20% (Atan); 58% reduced antibiotic use / hospitalization (Hellenthal).[2][7]
- Inflammatory/infectious complications — 54% (Tan).[11]
- Reoperation rate — 54% in Tan (avg 2.85 reoperations per affected pt) — though overall complications still decreased significantly from 3.38 to 1.16 per patient.[11]
- Conversion to ileal conduit — 0–17%; typically for intractable urethral incontinence or persistent fistula.[2][7]
Risk factors for adverse outcomes
Tan 2008: BMI trended toward significance (p=0.0569). Age, tobacco, diabetes, etiology, preoperative indwelling catheterization, and urethral closure were not significant predictors.[11]
Managing the Urethral Leakage Problem
Persistent urethral leakage is the Achilles' heel of ileovesicostomy. Options:[2][10][11][12]
- Anticholinergic medications — first-line for detrusor overactivity-related leakage.
- Pubovaginal sling — increased tension to achieve functional urethral closure; Chancellor demonstrated 100% continence in 14 women with destroyed urethras (5 in conjunction with ileovesicostomy).[10]
- Bladder-neck closure — 82–86% urethral continence; renders the procedure irreversible.[28]
- Conversion to ileal conduit + cystectomy — definitive solution for intractable leakage.[2]
Continent Ileovesicostomy (Casale Modification)
A separate continent modification using the Yang-Monti principle — a long, narrow catheterizable tube from a short ileal segment.[29] Distinct from the standard incontinent procedure; essentially a Monti channel.
Reversibility — A Unique Advantage
Because the native bladder and UVJs are preserved:[2][26]
- In neural recovery (incomplete SCI), the chimney can be excised and the bladder closed.
- The procedure can be converted to an ileal conduit if it fails.
- Particularly attractive for younger patients and those with potentially reversible neurologic conditions.
Long-Term Surveillance
Lifelong annual surveillance per AUA/SUFU:[5]
- Focused history, exam, symptom assessment (stoma, leakage, UTI, autonomic dysreflexia).
- Basic metabolic panel (hyperchloremic acidosis monitoring).
- Renal ultrasound for hydronephrosis and calculi.
- Stoma assessment for stenosis, retraction, parastomal hernia.
- Urodynamics to assess ongoing compliance and drainage adequacy.
Hellenthal: all 12 patients in the long-term cohort experienced some form of urinary tract problem during 5.5 yr of follow-up — continued surveillance is essential.[7]
Current Status
A valuable but niche procedure:[2][5][26]
- Best for patients with severe neurogenic bladder who cannot perform CIC, have suffered indwelling-catheter morbidity, and prefer a potentially reversible procedure over ileal conduit.
- Best applied to small bladders with severe overactivity where the goal is continuous low-pressure drainage.
- Patient selection is critical — severe preoperative detrusor hyperreflexia in women is a risk factor for persistent urethral leakage; concomitant outlet procedures (PVS or BNC) should be considered.
- High complication rate (54% reoperation rate in the largest series) and need for lifelong surveillance.
