Abstract

Objective: The aim of our study is to investigate the effect of average and maximum ureteral wall thicknesses measured by computed tomography before the operation on ureteroscopy results.

Materials and Methods: This prospective study was conducted with 103 patients who underwent ureteroscopy for ureteral stones between July and December 2021. The maximum ureteral wall thickness in the region of the ureteral stone and the average of the ureteral wall thicknesses measured from the 3-6-9-12 lines were calculated by non-contrast computed tomography. The operation time, residual stone, double j insertion status, and intraoperative complication status were examined according to the average ureteral wall thickness and maximum wall thickness.

Results: Of the 103 patients included in the study, 77 were male, and 26 were female. The mean age of the patients was 43.83±15.11 years. The mean stone length was 10.76±3.84 mm. The average ureteral wall thickness was 3.81±1.24 mm, while the maximum ureteral wall thickness was 4.9±1.8 mm. It was found that as the maximum, and average ureteral wall thickness increased, the operation time, residual stone, double insertion rate, and post-ureteroscopic lesion scale grade increased (p<0.05).

Conclusion: Maximum and average ureteral wall thicknesses are predictive factors for ureteroscopy results.

Ortalama ve Maksimum Üreter Duvar Kalınlığı Üreteroskopi Sonuçları için Öngörücü Faktör müdür?

Abstract

Amaç: Çalışmamızın amacı operasyon öncesi bilgisayarlı tomografi ile ölçülen ortalama ve maksimum üreter duvar kalınlıklarının üreteroskopi sonuçları üzerindeki etkisini araştırmaktır.

Materyal ve Metot: Bu prospektif çalışma Temmuz-Aralık 2021 tarihleri arasında üreter taşı nedeniyle üreteroskopi yapılan 103 hasta ile yapılmıştır. Kontrastsız bilgisayarlı tomografi ile üreter taşının olduğu bölgedeki maksimum üreter duvar kalınlığı ve 3-6-9-12 hizalarından ölçülen üreter duvar kalınlıkları ortalaması alındı. Ortalama üreter duvar kalınlığı ve maksimum duvar kalınlığına göre operasyon süresi, rezidü taş ve double j takılma durumu ve intraoperative komplikasyon durumu incelendi.

Bulgular: Çalışmaya dahil edilen 103 hastanın 77’si erkek, 26’sı kadındı. Hastaların yaş ortalaması 43,83±15,11 yıl idi. Ortalama taş uzunluğu 10,76±3,84 mm idi. Maksimum üreter duvar kalınlığı 4,9±1,8 mm iken ortalama üreter duvar kalınlığı 3,81±1,24 mm idi. Maksimum ve ortalama üreter duvar kalınlığı artıkça operasyon süresi, rezidü taş ve double takılma oranı, post üreteroskopik lezyon skala derecesinin arttığı görüldü (p<0,05).

Sonuç: Maksimum ve ortalama üreter duvar kalınlıkları üreteroskopi sonuçlarını öngörmede prediktif faktörlerdir.
