Summary
Longer-term Studer neobladder (SNB) outcomes show manageable complications and common renal function decline. Adhering to bladder emptying protocols may reduce complications and preserve renal function.
Area of Science:
- Urology
- Surgical Oncology
- Reconstructive Surgery
Background:
- Assessing long-term outcomes of Studer neobladder (SNB) urinary diversion.
- Evaluating functional, anatomical, and metabolic results post-SNB.
Purpose of the Study:
- To evaluate the longer-term functional, anatomical, and metabolic outcomes in patients who underwent Studer neobladder (SNB) urinary diversion.
- To identify predictors of poorer long-term renal function and complications.
Main Methods:
- Retrospective review of 116 patients undergoing SNB from 1995-2017.
- Analysis of demographics, comorbidities, pathological data, and functional, anatomical, and metabolic outcomes.
- Focus on voiding function, complications, renal function, nephrolithiasis, infections, and metabolic status.
Main Results:
- 72 patients with ≥1 year followup included (median 70 months).
- 22.2% required clean intermittent catheterization (CIC) due to bladder overdistension, renal decline, or urosepsis.
- Renal function generally declined; early hydronephrosis predicted poorer long-term renal function.
Conclusions:
- Long-term SNB followup indicates significant but manageable complications.
- Gradual decline in renal function is common; adherence to bladder emptying protocols (timed voiding or CIC) is crucial.
- Early hydronephrosis (<1 year) necessitates intervention to preserve renal function.
