Orthotopic neobladder techniques show comparable functional outcomes in bladder cancerBest bladder reconstruction technique? New analysis compares 14 options

AI-generated summary of the cited source, checked by automated accuracy review. How we work

Key Takeaway
Consider that most orthotopic neobladder techniques show comparable functional outcomes; only two significant pairwise differences were found.

This network meta-analysis evaluated 14 orthotopic neobladder reconstruction techniques in 1,129 patients undergoing radical cystectomy for bladder cancer. The analysis included techniques such as Studer pouch, T pouch, Xing pouch, Ileocecal pouch, Y pouch, Mainz pouch, and Camey I pouch, with Studer pouch as the reference.

Most comparisons showed no statistically significant differences across core functional outcomes. Only two pairwise comparisons reached significance: Studer pouch was superior to Camey I pouch for daytime continence (P < 0.05), and Ileocecal pouch achieved significantly lower postvoid residual volume than Studer pouch (P < 0.05).

SUCRA rankings suggested that T pouch ranked best for maximum neobladder capacity, Xing pouch for maximal flow rate, Ileocecal pouch for postvoid residual volume, Y pouch for daytime continence, and Mainz pouch for nighttime continence. However, these rankings are derived from a network meta-analysis that includes both observational and randomized studies, so causality cannot be inferred.

The authors note that SUCRA-derived rankings may facilitate individualized selection of orthotopic neobladder reconstruction techniques in clinical practice. Limitations include that most comparisons were not statistically significant and that the analysis is based on available data without reported follow-up duration or adverse events.

If you or someone you love has bladder cancer, surgery to remove the bladder is a major step. After that, surgeons often create a new bladder using a piece of intestine. But which technique works best? A new analysis looked at 14 different methods in over 1,100 patients.

The good news: most techniques performed about the same on key measures like bladder capacity and urine flow. But a few stood out. The Studer pouch was better than the Camey I pouch for daytime continence (staying dry during the day). The Ileocecal pouch led to less leftover urine after voiding compared to the Studer pouch.

Other techniques also showed promise. The T pouch ranked best for bladder capacity, the Xing pouch for urine flow rate, the Y pouch for daytime continence, and the Mainz pouch for nighttime continence. But these rankings are based on a statistical method called SUCRA, not direct head-to-head comparisons.

It's important to know that this analysis combined results from different types of studies, so it can't prove cause and effect. Most comparisons didn't find statistically significant differences. Still, the findings may help doctors and patients choose the best technique for each person's needs.

What this means for you:
Most bladder reconstruction techniques work similarly, but a few may offer specific advantages.

BackgroundOrthotopic neobladder (ONB) reconstruction is increasingly utilized following radical cystectomy (RC) for bladder cancer (BC). However, the comparative functional performance of different ONB techniques remains inconclusive.Materials and methodsA systematic review and network meta-analysis were conducted in accordance with the PRISMA-NMA guidelines. The study protocol was prospectively registered in PROSPERO (CRD420251143294). PubMed, EMBASE, and the Cochrane Library were systematically searched from database inception to October 2025. Eligible studies included those enrolled patients undergoing RC with any ONB technique and reported at least one predefined outcome: maximum neobladder capacity (MNC), maximal flow rate (MFR), postvoid residual volume (PVR), daytime continence (DC), or nighttime continence (NC). A Bayesian random-effects model was applied to synthesize direct and indirect evidence and to rank interventions using the surface under the cumulative ranking curve (SUCRA).ResultsFifteen studies involving 1,129 patients and 14 ONB reconstruction techniques were included. Most techniques showed no statistically significant differences compared with the Studer pouch across core functional outcomes. However, the Studer pouch demonstrated superior DC compared with the Camey I pouch, while the ileocecal pouch achieved significantly lower PVR than the Studer pouch (both P < 0.05). SUCRA-based rankings indicated that the T pouch, Xing pouch, Ileocecal pouch, Y pouch, and Mainz pouch performed best for MNC, MFR, PVR, DC, and NC, respectively.ConclusionAcross five core functional outcomes, most ONB reconstruction techniques demonstrated comparable performance. SUCRA-derived rankings may facilitate individualized selection of ONB reconstruction techniques in clinical practice.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420251143294, identifier CRD420251143294.
