Abstract

Objective: In our study, the functional prognosis of kidneys with prenatal urinomas were investigated. Material and methods: Between 2006 and 2010, fetal urinomas were detected in 19 fetuses using prenatal ultrasonography (US), and the medical records were reviewed retrospectively. Of the 19 cases, the follow-up data were available for 10 fetuses. The gestational age at diagnosis, prognosis of urinomas, clinical course and renal functions were recorded. Postnatal renal functions were assessed with renal scintigraphy. Results: Unilateral urinomas and increased parenchyma echogenicity in the ipsilateral kidney were detect- ed in all of the fetuses. Of the 10 fetuses with follow-up data, the option of termination was offered in 6 cases of anhydramnios, including 3 cases with signs of infravesical obstruction (a possible posterior urethral valve (PUV) and poor prognostic factors and 3 cases with unilateral hydronephrosis and increased echogenicity in the contralateral kidney. Only one family agreed the termination. The other 5 fetuses died during the early postnatal period. The average postnatal follow-up period in the 4 surviving fetuses was 22.5 months (8-38 months). One patient with a PUV underwent ablation surgery during the early postnatal period. In the postnatal period, none of the 4 kidneys that were ipsilateral to the urinoma were functional on scintigraphic evaluation. The urinomas disappeared in 3 cases. Nephrectomy was performed in one case due to recurrent urinary tract infections. Conclusion: In our study, no function was detected in the ipsilateral kidney of surviving patients with urino- mas. Upper urinary tract dilatation accompanied by a urinoma is a poor prognostic factor for renal function.

Özet

Amaç: Çalışmamızda prenatal urinom saptanan böbreklerde fonksiyonel prognoz incelenmiştir. Gereç ve yöntemler: Prenatal ultrason ile 2006-2010 yılları arasında 19 fetusta fetal ürinom saptanmış ve tıbbı kayıtlar retrospektif olarak değerlendirilmiştir. Bu 19 vakadan 10’nun takipleri mevcuttur. Tanı anın- daki gebelik haftası, urinomun prognozu, klinik seyir ve renal fonksiyonlar incelenmiştir. Postnatal renal fonksiyonlar sintigrafi ile değerlendirilmiştir. Bulgular: Tüm fetuslarda unilateral ürinom ve o taraftaki böbrekte artmış parankim ekojenitesi saptan- mıştır. Takibi olan 10 fetusten, kötü prognostik faktörlere sahip ve infravezikal obstruksiyon düşünülen 3 olguya (muhtemel posterior uretral valv (PUV)) ve tek taraflı hidronefroz ve karşı böbrekte artmış ekojenite saptanan 3 vakaya terminasyon önerilmiştir. Sadece 1 aile terminasyonu kabul etmiştir. Diğer 5 fetus erken post natal dönemde exitus olmuştur. Hayatta kalan diğer 4 fetusun ortalama post natal takip süresi 22.5 (8-38) aydır. PUV’lu bir olguya erken post natal dönemde ablasyon yapılmıştır. Sintigrafi ile değerlendiril- diğinde fetal ürinomlu 4 böbreğin hiç birinde fonksiyon saptanmıştır. Ürinomlar 3 vakada kaybolmuştur. Tekrarlayan üriner sistem enfeksiyon nedeniyle bir vakaya nefrektomi yapılmıştır. Sonuç: Çalışmamızda aynı tarafta urinomu olan hiçbir hastada renal fonksiyon saptanmamıştır. Ürinomun eşlik ettiği üst sistem dilatasyonu renal fonksiyonlar için kötü prognostik göstergedir.
