Perkutanöz Nefrolitotomide Parankim Kalınlığının BT ve Tc-99m DMSA Sintigrafisi ile Karşılaştırılmas

Amaç: Perkutanöz nefrolitotomi PNL büyük ve komplike renal callus tedavisinde kullanılan cerrahi yöntemlerdendir. Hemoraji PNL'nin en önemli komplikasyonlarından biri olarak bildirilmektedir. Gelişen hemorajinin böbrek parankim kalınlığı ile ilişkili olabileceğini bildiren yayınlar bulunmaktadır. Çalışmamızın amacı PNL öncesi bilgisayarlı tomografi BT ve Tc-99m DMSA ile ölçülen böbrek boyutları ve parankim kalınlıklarının karşılaştırılması ve aralarında korelasyon olup olmadığının saptanmasıdır. Metaryal ve metod: Çalışmaya PNL öncesi abdomen tomografileri ve Tc-99m DMSA ile renal kortikal sintigrafileri çekilmiş 16 hasta dahil edildi. Hastaların böbrek boyutları, üst, orta ve alt pollerden böbrek parankim kalınlıkları ile ortalama parankim kalınlıkları hesaplandı. Bulgular: Ortalama parankim kalınlığı BT'de sağ böbrek için 18.68±5.41 mm, sol böbrek için 17.62± 4.55 mm olarak hesaplandı. DMSA sintigrafisinde ise ortalama parankim kalınlığı sağ böbrek için 15,27±3.30 mm, sol böbrek için 16.27± 3.89 mm olarak hesaplandı. Ortalama böbrek boyutları BT'de sağ için 99.49 ± 18.92 x 46.53 ± 12 mm, sol için 95.40± 11.91x45.58± 11.23 mm olarak hesaplanırken, sintigrafide sağ için 106.66 ± 18.48x 47.36 ± 11.52 mm, sol için 104.37±18.28x 46.26±12.94 mm olarak hesaplandı. Sonuçta DMSA sintigrafisi ile BT'den ölçülen parankim kalınlığı ve böbrek boyut ölçümleri arasında anlamlı korelasyon görüldü p

The Comprassion of Parenchymal Thickness with CT and DMSA Scintigraphy in Percutaneous Nephrolithotomy

Background: Percutaneous nephrolithotomy PNL is one of the surgical methods used in the treatment of large and complex renal callus. Hemorrhage has been reported as one of the major complications of PNL. There are publications reporting that composed hemorrhage may be associated with renal parenchymal thickness. The aim of this study is to compare the sizes and parenchymal thickness of kidneys measured by computed tomography CT and Tc-99m DMSA scintigraphy before PNL and determine whether there is a correlation between them. Methods: Sixteen patients who performed abdominal CT scan and Tc-99m DMSA renal cortical scintigraphy before PNL, were included to study. The patients' kidney sizes, parenchymal thicknesses from upper, middle and lower poles and mean parenchymal thicknesses were calculated. Results: The mean parenchymal thickness was calculated as 18.68±5.41 mm for right kidney and 17.62± 4.55 mm for left kidney on CTscan. On DMSAscintigraphy, the mean parenchymal thickness was calculated as 15,27±3.30 mm for right kidney and 16.27± 3.89 mm for left kidney. While the mean kidney sizes were calculated as 99.49 ± 18.92 x 46.53 ± 12 mm for right and 95.40± 11.91x45.58± 11.23 in left on CTscan, they were calculated as 106.66 ± 18.48x 47.36 ± 11.52 mm for right and 104.37±18.28x 46.26±12.94 for left on scintigraphy. As a result, a significant correlation was seen between parenchymal thicknesses and kidney sizes measured by DMSAscintigraphy and CTscan p
