Abstract

AMAÇ: Ürolitiazis her yaşı etkileyebilen sık görülen üriner bir patolojidir. Ürolitiazis için çekilen bilgisayarlı tomografi (BT) ile tüm abdominal organlar görüntülenmektedir. Renal ve ekstrarenal insidental bulguya (İB’ya) rastlanabilmektedir. Bu çalışmada ürolitiazis için abdomen BT çekilen hastalarda İB sıklığını değerlendirmeyi amaçladık.
GEREÇ VE YÖNTEM: Ocak 2019 - 2020 tarihleri arasında ürolitiazis ön tanısı ile poliklinikten yönlendirilerek abdominal BT çekilen hastalar retrospektif olarak tarandı. 1056 hasta çalışmaya dahil edildi. Bulgular renal, ekstrarenal; klinik önemli ve önemsiz bulgular olarak sınıflandırıldı. Klinik önemli bulgular 65 yaş üstü ve 65 yaş altı grupta değerlendirildi. İleri görüntüleme veya işlem gerektiren hastalar, klinik önemli hasta grubu olarak değerlendirildi.
BULGULAR: 1056 hastanın 549 (%52) tanesi erkek, 507 (%48) tanesi kadın hastaydı. Hastaların yaş ortalaması 50,55±14,95 yıldı. Altı yüz kırk beş (%61) hastada üriner sistem taşı, 675 (%63,9) hastada İB saptandı. Üç yüz iki (%28,59) hastada 304 tane insidental renal bulgu mevcuttu. Üç yüz seksen üç (%36,26) hastada ise ekstrarenal 725 bulgu saptandı. On hastada hem renal hem de ekstrarenal İB mevcuttu. Ekstrarenal İB’lar içerisinde 413 (%56,8) hastada hepatobiliyer sistemde, 136 (%18,7) hastada gastrointestinal sistemde ve 41 hastada adrenal bezde (%5,6) İB mevcuttu. 47 (%4,45) hastada klinik önemli İB saptandı. Klinik önemli İB’lar 65 yaş üstü grupta %7,23 oranında ve 65 yaş altı grupta %3,71 oranında tespit edildi.
SONUÇ: İB’lara abdomen BT’de sık rastlanır ve çoğunluğu klinik olarak önemsizdir. Yaş ile birlikte klinik önemli İB varlığında artış olmaktadır. Özellikle ileri yaş hastalarda bu bulguların asemptomatik dönemde erken tespit edilmesi ile hastaların sağ

FREQUENCY OF INCIDENTAL FINDINGS IN UNENHANCED ABDOMINAL COMPUTED TOMOGRAPHY FOR DIAGNOSIS OF URINERY SYSTEM STONE

Abstract

OBJECTIVE: Urolithiasis is a common urinary tract pathology that can affect all age groups. All abdominal organs are imaged with computed tomography (CT) taken for urolithiasis. Therefore, renal and extrarenal incidental findings (IFs) may be encountered. In this study, we aimed to evaluate the incidence of IF in the patients who took abdominal CT for urolithiasis.
MATERIAL AND METHODS: Patients referred to the outpatient clinic with a pre-diagnosis of urolithiasis and who took abdominal CT between January 2019 and 2020 were evaluated retrospectively. One thousand fifty-six patients were included in the study. IFs were classified as renal - extrarenal, clinically significant - clinically insignificant findings. Clinically significant findings were evaluated in the over-65 and under-65 age groups. Patients requiring additional imaging and procedures were evaluated as a clinically significant patient group.
RESULTS: Five hundred and forty-nine (52%) of 1056 patients were male, and 507 (48%) were female. The mean age of the patients was 50.55 ± 14.95 years. Six hundred and forty-five (61%) patients had urinary stones, IF was found in 675 (63.9%) patients. Three hundred and four renal IFs were present in 302 (28.59%) patients. In 383 (36.26%) patients, 725 extrarenal findings were detected. Ten patients had both renal and extrarenal IF. In the extrarenal IFs, 413 (56.8%) patients had findings in the hepatobiliary system, 136 (18.7%) patients in the gastrointestinal system, and 41 patients (5.6%) in the adrenal gland. Clinically significant IFs were detected in 47 (4.45%) patients. Clinically significant IF was detected in 7.23% in the patient group over 65 years of age and 3.71% in the under-65 age group.
CONCLUSIONS: IFs are common in abdominal CT and most of them are clinically insignificant. The presence of clinically significant IF increases with age. It should be kept in mind that especially in elderly patients, the early detection of these findings in the asymptomatic period increases the survival and treatment chances of the patients.
