Abstract

Objective: This study aimed to distinguish between obstructive and non-obstructive dilation of the upper urinary tract using ureterovesical jet Áow analysis with Doppler ultrasonography (US) and manual Áank compression. Materials and methods: The study enrolled 54 patients (11 women, 43 men; mean age 27.5 years) with unilateral hydronephrosis. All but 2 pregnant patients underwent the Doppler US and the reference standard test [intravenous pyelogram (IVP)] after standardized hydration. The distended urinary bladder was visual- ized in the transverse plane to evaluate both ureteral oriÀ ces simultaneously. During and after compression of each Áank, the jet Á ows were recor ded in Doppler mode. The jet Áows were quantiÀed by calculating the longitudinal extent of the color spread into the bladder on both sides. The sensitivity, speciÀcity, positive predictive value, negative predictive value, and accuracy of the test for determining the degree of obstruction were evaluated statistically. Results: Ureterovesical jet Áow could not be visualized with Áank compression in 4 cases. Three of these cases had complete obstruction on IVP. In the 22 cases that had markedly reduced Áow compared to the contralateral side on Doppler US, the IVP showed similar stasis. In the 19 cases that had mildly diminished Áow compared to the contralateral side on Doppler US, no signiÀcant difference was detected in the pyelogram and nephrogram phases on IVP. Conclusion: Doppler examination of the ureterovesical jet Áows during Áank compression may be a good diagnostic method for evaluating the degree of obstruction, especially in patients in whom magnetic resonance imaging or computerized tomography is contraindicated.

Özet

Amaç: Bu çalışmanın amacı, manuel kompresyon sırasında üreteral jet akımların Doppler ultrasonografi (US) ile değerlendirilerek tıkayıcı ve tıkayıcı olmayan üst üriner sistemin dilatasyonlarını ayırt edilmesidir. Gereç ve yöntem: Çalışmaya tek taraflı hidronefroz tespit edilmiş 54 olgu (11 kadın, 43 erkek; ortalama yaş 27.5 yıl) dahil edildi. Hidrasyon düzeyi standardize edilerek, tüm hastalara Doppler US inceleme ve 2 gebe olgu dışındaki diğer tüm hastalara referans standart test olarak intravenöz piyelografi (İVP) yapıldı. Her iki üreter orifisi görülecek şekilde distandü mesane yatay pozisyonda görüntülendi. Renal lojun kompresyonu sırasında ve sonrasında oluşan jet akımlar Doppler mod ile kaydedildi. Mesane içerisine doğru gelişen renk saçılımının uzunluğu dikkate alınarak jet akımlar kantifiye edildi. Obstrüksiyon derecesinin ayırımında sensisitivite, spesifite, pozitif ve negatif prediktif değerler istatistiksel olarak hesaplandı. Bulgular: Üreterovezikal bileşke akımı toplam 4 olguda hiç gözlenemedi. Bunlardan biri hariç diğer üçünde İVP ile de tam obstrüksiyon rapor edilmişti. Kalan olguların 22’sinde, Doppler US’de karşı tarafa göre kısalmış jetler sözkonusu iken, İVP’de de bununla uyumlu nonprogresif staz görüldü. Diğer 19 olguda, Doppler US’de karşı tarafa göre hafif azalmış jetler sözkonusu iken İVP incelemelerinde piyelogram ve nefrogram fazlarında anlamlı fark tespit edilmemişti. Sonuç: Özellikle manyetik rezonans görüntüleme veya bilgisayarlı tomografinin kontrendike olduğu olgularda, renal lojların manuel kompresyonu sırasında Doppler US ile üreterovezikal bileşkenin jet akımlarının değerlendirilmesi obstrüksiyon derecesinin belirlenmesinde iyi bir tanısal yöntem olabilir.
