Cutaneous Vesicostomy
"Vesicostomy" literally means an opening into the bladder, but the term covers two clinically distinct categories that should be separated explicitly:[1][3]
| Category | Stoma type | Continence | Drainage |
|---|---|---|---|
| Incontinent (cutaneous) vesicostomy | Open dome-to-skin stoma; no continence mechanism | None | Free drainage into a diaper or pad |
| Continent (catheterizable) vesicostomy | Catheterizable channel with a continence mechanism | Yes | Clean intermittent catheterization |
This page focuses on the incontinent form (Blocksom and Lapides) and indexes the continent alternatives, all of which are covered in their own dedicated pages.
For continent vesicostomy options, see:
- Appendicovesicostomy (Mitrofanoff) — gold-standard appendiceal channel.
- Yang-Monti Channel — retubularized ileum (with Double Monti, Casale spiral, Tapered).
- Tubularized Bladder Flap — bowel-free continent vesicostomy from native bladder wall (Casale/Rink, Peard, Yachia, Stief-Becker, Klauber-Cendron, Casella-Ost hybrid).
- Hemi-Kock Continent Stoma — ileal-augmentation channel with stapled intussusception nipple valve.
- Indiana Augmentation Cystoplasty (IAC) — ileocecal augmentation with plicated-ileocecal-valve continent channel.
- Principles of Continent Catheterizable Channels — design rules common to all of the above.
Blocksom Vesicostomy
The simplest tubeless cystocutaneous fistula, described by Blocksom in 1957 — the bladder dome is brought to the suprapubic skin and sutured directly to the skin edges, draining freely into a diaper or absorbent pad.[2][5]
Technique
- Small transverse or vertical suprapubic incision.
- Bladder dome mobilized to the skin surface.
- Bladder wall sutured directly to the skin edges as a flush stoma.
- No tube or catheter required — gravity drainage into a diaper or pad.[2][5]
Indications
- Pediatric. Temporary urinary drainage in infants and young children with neurogenic bladder (spina bifida), posterior urethral valves, vesicoureteral reflux, or other congenital lower-tract anomalies — a bridge until the child is old enough for CIC or definitive reconstruction.[1][6][7]
- Elderly / debilitated adults. Chronic urinary retention in patients with severe dementia, neurogenic bladder, or advanced prostate cancer who cannot manage catheters.[2][8]
Outcomes
- Snyder n = 48 (spina bifida, pediatric). Excellent temporary decompression with no loss of bladder volume while diverted; of 16 who underwent closure, 12 were continent on CIC.[6]
- Tobu n = 16 (elderly, mean age 78.6 yr, mean follow-up 55.7 mo). Catheter-free in 87.5%; complications 37.5% (all within 2 yr); only 2 required reoperation.[2]
- Fischer n = 67 (single institution, average duration 14.3 yr). Many patients keep their vesicostomy permanently into adulthood with high satisfaction; 80.6% of the still-vesicostomy cohort had spina bifida.[9]
Complications
- Stomal stenosis 14.8–20%.[10][7]
- Stomal prolapse — uncommon; may need revision.[11]
- UTI 14.8%.[10]
- Recurrent upper-tract calculi 33% in one series.[11]
- Revision 7.4–20%.[10][7]
Lapides Vesicostomy
A modification using a U-shaped bladder-wall flap brought to the skin, providing a wider stoma less prone to contracture. The Di Benedetto pediatric series (n = 27) reported a revision rate of only 7.4%.[10]
Differences from Blocksom:
- Uses a flap of bladder wall rather than direct dome-to-skin suturing.
- Wider, more durable stoma.
- Still incontinent — no continence mechanism.
Permanent vs Temporary Vesicostomy
Although traditionally a temporary diversion, a substantial proportion of severely affected patients keep the vesicostomy for life:[9][11]
- Hutcheson n = 23 (myelomeningocele) — permanent vesicostomy resolved hydronephrosis in all; described as "an acceptable alternative when continence is not realistic."[11]
- Fischer 53.7% still had their vesicostomy at last follow-up (average 14.3 yr) with high satisfaction.[9]
Bladder-Neck Closure + Continent Vesicostomy — the "Last Resort"
When the bladder outlet is non-reconstructible (recurrent post-prostatectomy stricture with incontinence, post-vulvectomy, severe neurogenic outlet failure), the bladder neck is surgically closed and a continent vesicostomy becomes the sole drainage route.[22][23]
Spahn / Riedmiller n = 17
Mean follow-up 68 months:[22]
- Indications: recurrent anastomotic stricture + post-prostatectomy incontinence (59%), neurogenic bladder (35%), post-vulvectomy (6%).
- Continent outlet: appendicovesicostomy (n = 8) or ileal-intussusception valve (n = 9).
- Simultaneous ileocecal augmentation in 9 patients with reduced capacity.
- Primary bladder-neck closure 100% successful.
- Primary continence 82%.
- 3 (18%) had continence failure (2 from reduced capacity, 1 iatrogenic) — all reconstructed successfully.
- Stomal stenosis 23% (3/8 abdominal, 1/9 umbilical).
- Stoma placed using the "butterfly technique" (8) or at the umbilicus (9).
Reid n = 24 (10 with bladder-neck closure)
Closure successful in 8/10; CIC through abdominal stoma was "cleaner and more aesthetically pleasing"; a dry perineum reduces skin breakdown.[23]
Combined Bladder-Neck Reconstruction + Continent Stoma — bladder exstrophy
Kasprenski n = 24 (exstrophy), median age 8.9 yr:[24]
- 71% completely dry for ≥3-hour intervals.
- 29% did not achieve continence; 60% of failures had subsequent bladder-neck transection.
- Offers volitional voiding while maintaining a continent stoma as backup.
Benchekroun Hydraulic Ileal Valve (Historical)
Described by Benchekroun in 1975 (Morocco): a 14 cm ileal segment intussuscepted into itself along its entire length functions as a hydraulic check valve on the inkwell principle — retrograde reservoir pressure collapses the inner tube, preventing efflux while permitting catheter passage.[15][19]
Outcomes
- Benchekroun original n = 136 (13 yr). 75% immediately continent; 93.4% continent after valve repair; self-catheterization easy in 88.3%.[15]
- Quinlan / Leonard (Johns Hopkins) n = 15. All continent diurnally and nocturnally; revision 33% (vs 58% with plicated ileal efferents); described as their "continence mechanism of choice" at the time.[16][20]
- Sanda / Gearhart n = 11 at 5 yr. Only 13% had complications at 18 months, but 91% required revision by 5 yr — stomal stenosis 73%, calculi 36%, devagination 36%; 64% needed major revision. Authors concluded that "novel forms of urinary diversion require extended follow-up for accurate assessment."[21]
- Hanna pediatric experience. 4/5 children developed stomal stenosis, 1 had valve perforation; only 1 of 5 still doing well at 6 years; described as "disappointing"; recommended Monti or Nissen-valve alternatives.[13]
- Guzman modification. Suture rather than staple stabilization of the inner tube; eliminated staples, reducing stone and fistula risk; all 7 continent at 6 mo–2 yr.[19]
Current status. Largely abandoned because of unacceptably high long-term stenosis and devagination rates; included here for historical and lineage completeness.[13][21]
Continence Mechanisms — At-a-Glance
| Mechanism | Principle | Channels using it |
|---|---|---|
| Flap valve (submucosal tunnel) | Channel runs along reservoir wall; rising pressure compresses channel against backing wall | Mitrofanoff (APV), Yang-Monti, TBF Casale/Rink |
| Intussusception nipple valve | Channel telescoped into reservoir; pressure collapses nipple lumen | Hemi-Kock, Kock pouch, TBF Peard |
| Hydraulic collapse (inkwell) | Intussuscepted ileal segment collapses under retrograde reservoir pressure | Benchekroun valve (largely abandoned) |
| Rectus-muscle compression | Channel passes through crossed rectus strands; lateral pressure adds to closure | TBF Yachia |
| Nissen fundoplication | Reservoir wall wrapped around channel base | Richter / Hanna Nissen valve |
| Plicated ileocecal valve + tapered ileum | Native valve reinforced; ileal peristalsis assists | Indiana pouch, IAC |
| Lich-Gregoir extravesical detrusor tunnel | Channel embedded in detrusor trough; muscle compression provides continence | TBF Stief-Becker, extravesical implantation[25] |
The Riley extravesical implantation experience (VanderBrink n = 84 of 394) reported 94% stomal continence with a 26% revision rate at mean 45 months (mostly skin-level or endoscopic), with the advantage of avoiding a large cystotomy.[25]
Stomal Stenosis — the Universal Challenge
Across all continent vesicostomy techniques, stomal stenosis is the dominant complication.
- Overall incidence 6–45% depending on technique and follow-up.[3][17][26]
- Most occur within the first year post-reconstruction (mean 6–9 months).[17]
- Risk factors: umbilical stoma (86% in some series); female sex; multifilament suture for umbilicoplasty (vs monofilament, p = 0.009); neuropathic bladder (60%); urothelial-lined channels (TBF) higher than intestinal-mucosa-lined channels.[3][27][26]
- Etiology (Harris n = 260 exstrophy): scar contracture 63%, keloid 26%, hypertrophic scar 11%.[27]
- Management: L-stent (knotted catheter flush with skin overnight); stomal incision (100% for scar contractures); excision with local tissue rearrangement (66.7% for hypertrophic / keloid); balloon dilation (variable); surgical revision required in ~50%.[27][28][4][17]
De Ganck's summary stands: "a high easy-to-treat complication rate is the price for a continent stoma." Despite a 36% complication rate, most were easy to treat and patient satisfaction stayed high.[26]
Other Channel Complications
- Stomal incontinence 2–6%.[12][29]
- False passage 5–10% — most managed by catheter drainage.[18][17]
- Channel stricture 6% — operative or endoscopic resection.[29]
- Stomal prolapse 5% — usually late; operative revision.[29]
- Channel leakage 6–9% — endoscopic bulking-agent injection successful in ~50%.[29]
- Recurrent UTI 12–36%.[26]
- Bladder stones 6–10%.[26]
Welk noted that complications "appear to occur throughout the life of the channel," with some appearing years after construction — emphasizing the need for lifelong surveillance.[29]
Decision Algorithm — Which Vesicostomy
Temporary urinary drainage (infants / children)
- Blocksom — simple, tubeless, reversible; ideal for infants with neurogenic bladder, PUV, or severe reflux as a bridge to CIC or reconstruction.[6][1][7]
- Lapides — wider stoma, may have lower stenosis rate.[10]
Permanent incontinent drainage (elderly / debilitated)
- Blocksom — useful in elderly patients with chronic retention and severe dementia who cannot manage catheters.[2][8]
Continent catheterizable stoma
- First choice: Appendicovesicostomy.[12]
- Appendix unavailable + adequate bladder capacity: Tubularized Bladder Flap.[18][3]
- Appendix unavailable + capacity marginal or augmentation needed: Yang-Monti (channel + augmentation patch from one pedicle).[3]
- Augmentation + continent stoma in adults (single bowel segment): IAC or Hemi-Kock.[22]
- Devastated bladder outlet: bladder-neck closure + continent vesicostomy (APV, ileal intussusception valve, or TBF) — see above.[22][23]
Special Populations
- Bladder exstrophy. Continent stoma creation is common after failed bladder-neck reconstruction. Largest exstrophy-specific series (Harris n = 260): stomal stenosis 25% at median 1.9 yr; monofilament umbilicoplasty suture significantly reduced stenosis (p = 0.009).[27]
- Myelomeningocele. Vesicostomy plays a central role across the lifespan — incontinent for safe infant decompression; transition to CIC ± continent reconstruction at 6–10 yr; some with severe disability retain permanent incontinent vesicostomy with high satisfaction.[6][11][9]
- Adults with devastated outlet. Continent vesicostomy with bladder-neck closure is the "last resort" — primary continence ~82% with appropriate technique selection.[22]
