Background/Aim: There are different management options in infants with obstructive
megaureter. Herein, we aimed to present a case of 43
day-old female infant who underwent refluxing ureterocystostomy because of ureterovesical
obstruction.
Case: The patient whose bilateral hydronephrosis was detected during antenatal period was born at 35th gestational week by cesarean section. Ultrasonographic examinations in postnatal period showed progressively worsening grade IV hydronephrosis at right kidney (parenchymal thickness: 5 mm, renal pelvis AP diameter: 27 mm) and grade II hydronephrosis at left kidney (parenchymal thickness: 10 mm, renal pelvis AP diameter: 5 mm). Right ureter was tortuous and its diameter was 11-12 mm at distal end. MAG-3 scintigraphy showed significantly delayed excretion, decreased concentration and a dilated ureter with a split function of 42%. There was no washout of radiotracer after diuretic injection combined with right ureteric visualization. Left kidney showed minimal delayed excretion, normal concentration with a split function of 58%. There was partial response to diuretic injection. Voiding cystourethrogram showed no pathological finding. At 43 day-old, the patient underwent cystoscopy that revealed normal bladder and severe stenosis in both ureteral orifices. Ureteral catheterization could not be achieved. Because radiologic and scintigraphic findings were within normal limits on the left side, just right-sided refluxing ureterocystosomy (extravesical, side-to-side) was done. The patient was discharged from hospital on post-operative day 3 without any complication. She has been following up on antibiotic prophylaxis for 11 months.
Conclusion: In patients with obstructive megaureter,
surgical intervention may be required in early infancy in case of progressively
worsening hydronephrosis. In those patients, refluxing ureterocystostomy is an
option to protect upper urinary tract if endoscopic interventions could not be successful.

Önbillgi/Amaç: Obstrüktif megaüreterli bir
yaşından küçük olguların tedavisinde farklı yaklaşımlar vardır. Burada, üreterovezikal darlık
nedeni ile reflüksif üreterosistostomi yapılmış 43 günlük bir kız hastayı sunmayı amaçladık.
Olgu: Antenatal takiplerinde bilateral hidronefroz
saptanan hasta 34’üncü gebelik haftasında sezaryen ile doğmuş. Hastanın
postnatal yapılan ultrasonografilerinde sağ böbrekte progressif artış gösteren
grade IV hidronefroz (parankim
kalınlığı
Sonuç: Hidronefrozun progressif olarak arttığı obstrüktif megaüreter olgularında erken süt çocukluğu döneminde cerrahi girişim gerekebilir. Bu olgularda endoskopik girişimlerin başarısız olması durumunda, reflüksif üreterosistostomi erken dönemde üst üriner sistemi koruma amacı ile tercih edilebilecek bir yöntemdir.
