[Renal transplantation in patients with neurogenic bladder].

BACKGROUND

Renal transplantation can be done in patients with neurogenic bladder and clean intermittent self catheterization maintains renal function

AIM

To retrospective assess the results of renal transplantation in patients with neurogenic bladder.

PATIENTS AND METHODS

The medical records of seven patients aged 10 to 22 years old (3 female) followed during 7 to 32 months were reviewed. All patients had urinary tract infection, prior to transplantation, were instructed on self catheterization and received tri-associated immunosuppression.

RESULTS

Grafts came from alive related donors in 5 patients and from cadavers in two. Prior to transplantation, three patients were subjected to nephrectomy and three to bladder enlargement, leaving a pigtail catheter. After transplantation, one lymphocele was drained, one uretherostomy due to an impacted lithiasis and one nephrectomy plus vesical enlargement due to intravesical pressures over 40 cm H2O, were done. One uretheral stricture was treated with dilatation. Seven episodes of pyelonephritis, 19 urinary tract infections and 77 asymptomatic bacteriurias were documented. Serum creatinine at the end of follow up ranged from 0.7 to 2.1 mg/dl. There were 0.7 acute rejection episodes per patient and all grafts survived.

CONCLUSIONS

Renal transplantation in patients with neurogenic bladder is feasible, performing a vesical enlargement. There is however a high frequency of infectious episodes.
