The Outcome of Pre-transplant Bladder Cycling in Patients With Defunctionalized Bladder

Kidney transplantation still remains the best treatment for end-stage renal disease (ESRD). Indeed, increasing numbers of patients are referred for transplantation, but there has been no concomitant increase in the supply of kidneys from the traditional donor pool. Many potential recipients awaiting transplantation, therefore must undergo dialysis for a long time. Regarding the detrimental effect of long-term dialysis associated with oliguria or anuria on the lower urinary tract, and especially in bladder, the interruption of physiological cycle of storage and voiding brings to a situation called Defunctionalized Bladder (DB) in which the bladder capacity became smaller in size. (Errando et al 2018).

In this study we will evaluate the outcome of renal transplantation into a defunctionalized bladder by comparing direct transplantation into this defunctionalized bladder and pre-transplant programmed bladder cycling.

Inclusion criteria

• Age: 16 years and older.
• ESRD patients maintained on hemodialysis for more than 12 months.
• Have oliguria or anuria
• reduced bladder capacity (less than 100 ml) assessed by cystogram.

Exclusion criteria

• 1- Previous bladder or pelvic surgery or procedure having affected the bladder function.

2- Neurogenic bladder dysfunction. 3-Patients with history of lower urinary tract symptoms before developing renal failure.

4-Those with lower urinary tract disease resulting in renal failure.
