ABSTRACT
A transplant of a portion of the bladder with an en bloc kidney from a 2-year-old donor was previously reported in a 12-month-old girl due to her extremely small bladder. Bilateral kidneys were transplanted en bloc with their ureters connected to a patch of the donor bladder (bladder patch technique). The long-term outcomes and complications of this technique have not been documented. Here, we report a long-term, 17-year follow-up of this patient with an evaluation of whole bladder functions at 18 years of age. The patient has had no episodes of urinary tract infections. Cystoscopy showed a viable transplanted bladder with a well-perfused mucosa. We observed that the native bladder has stretched over time, forming more than half of the bladder wall. Urodynamic studies showed preserved bladder compliance at 43 mL/cmH2O, and native bladder contractility was preserved. Prolonged voiding time and postvoid residual urine were also observed. These findings were suggestive of detrusor underactivity. No reï¬ux across the donor ureterovesical junctions was observed. The recipient was instructed to continue timed voiding and double voiding to empty the bladder. In conclusion, en bloc kidney transplantation with a bladder patch is a feasible and safe option for kidney transplant recipients with a small bladder capacity.
