Objectives: The aim of this study was to investigate the
effects of antegrade balloon dilatation on ureteral
strictures that developed after kidney transplant.
Materials and Methods: The hospital databases of the
Erasmus Medical Center (Rotterdam, The Netherlands)
and the Academic Medical Center (Amsterdam, The
Netherlands) were retrospectively screened for patients
who underwent balloon dilatation after kidney
transplant. Balloon dilatation was technically
successful whenever it was able to pass the strictured
segment with the guidewire followed by balloon
inflation; the procedure was clinically successful if no
further interventions (for example, surgical revision of
the ureteroneocystostomy or prolonged double J
placement) were necessary.
Results: Fifty patients (2.4%) of 2075 kidney transplant
recipients underwent antegrade balloon dilatation
because of urinary outflow obstruction. Median time
between transplant and balloon dilatation was 3
months (range, 0-139 mo). In 43 patients (86%),
balloon dilatation was technically successful. In the
remaining 7 patients (14%), it was impossible to pass
the strictured segment with the guidewire. In 20 of 43
patients (47%) having a technically successful proce -
dure, the procedure was also clinically successful, with
median follow-up after balloon dilatation of 35.5
months (range, 0-102 mo). We did not identify any
patient or stricture characteristic that influenced the
outcome of treatment.
Conclusions: Balloon dilatation is a good option for
ureter stricture treatment after kidney transplant as it
is minimal invasive and can prevent surgical
exploration in almost 50% of cases.
