Kidney transplantation is the most effective treatment for end-stage
renal disease; however, long-term graft survival largely depends on the
functional integrity of the lower urinary tract. Bladder disorders and voiding
dysfunction after transplantation are common, particularly in patients with a
history of prolonged anuria or oliguria. These conditions are associated with
reduced bladder capacity, impaired compliance, and detrusor dysfunction.
Comprehensive evaluation, including clinical assessment, uroflowmetry,
post-void residual measurement, and selective urodynamic studies, is essential
for identifying high-risk patients. Common dysfunction patterns include
low-capacity bladder, overactive bladder, hypocontractile bladder, and
neurogenic bladder. If untreated, these conditions may lead to complications
such as urinary tract infections, vesicoureteral reflux, and obstructive
uropathy, ultimately compromising graft function. A stepwise management
approach, incorporating pharmacological therapy, clean intermittent
catheterization, and surgical interventions, is crucial for optimizing outcomes
and preserving long-term graft function.
