Aim
The aim of this study was to examine patients
who had vesicoureteral obstruction after
undergoing subureteric injection for vesicoureteral reflux(VUR).
Patiens and methods
Between years 2000-2016, 249 patients that
underwent subureteric injection with a diagnosis of VUR were evaluated
retrospectively. For each patients; age,
gender, side of VUR, the injection material, physical examination and imaging
findings were compared.
Results
Of the patients, 146 were female, 103 were
male. Median age was 5.4 years (1 month-23years). In total, 249 patients
underwent injection of 447 renal units (RU). Recurrent injections were applied
in 45 patients. 135 patients (54.21%) had bilateral, 50 (20.08%) had right, 63
(25.3%) had left VUR detected and injections were applied accordingly. In 1
patient VUR of a transplanted kidney was determined and injections were
performed.
The renal units 126 to Deflux®, 119 to
Dexell®, 33 to Vurdex®, 23 to Urodex® 18 to Vantris®, 44 to Coaptite®, 2 to
Macroplastique® injection material has been applied. In 62 patients used materials were unknown.
In follow up 5 patients had obstruction
signs. In early period (1day-20days) 2
of these had acute renal failure with hydroureteronephrosis and an increase in
blood creatinin levels. Obstruction findings in these patients improved after
percutaneous nephrostomy drainage. In late period (12-13-18 months) other 3
patients had hydroureteronephrosis and üreterovesical obstruction signs
occured. All of these patiens that had late period obstruction needed
ureterorenocystostomy. In 1 of the early period obstruction patients Dexell® injection
was used ,and in other 4 patients Vantris® injection was used.
Conclussion
In
our series of patients who underwent subureteric injection secondary to
vesicouethral reflux, a low-rate of obstruction findings occured. These findings resulted in acute renal
failure in acute, and renal function loss and kidney loss in chronic period.
These findigs therefore should be of considerance during early and late
follow-up periods.
