Abstract

Aim: Although the advantage of ureteral double j
(D/J) stenting has been shown in reducing post- operative pain after
ureteroscopic surgery, its contribution to stone clearance for additional
treatment has not been fully assessed. In this study we aimed to evaluate the
effect of stenting on stone free rates at the end of the additional treatment.

Methods: We reviewed the medical records of all
patients who underwent flexible ureterorenoscopy (FURS) for kidney stones
between October 2009 and January 2015. Patients with malignant ureteral
stricture, severe skeletal malformation, renal unit malformation, non-opaque
renal stone or lost to follow-up were excluded. 47 of 289 patients (stenting 24
patients, non-stenting 23 patients) assessed. The perioperative and
postoperative parameters and stone-free rates were compared in patients whether
they had intraoperative D/J stent (group 1) or not (group 2).

Results: No differences were found between groups according to age, gender, body mass index, operation history, preoperative stenting history, shockwave lithotripsy history, ureteral stricture, stone size, access sheath rate, retreatment, or additional treatment number and stone location. Operation time was significantly higher in group 1. Those who refused additional treatment were insignificantly lower in group 1. Although the stone-free rates were similar for the two groups at the end of the first month, the stone-free rates after the additional treatments were significantly higher in group 1.





Conclusion: Stenting during FURS, improved the stone-free
rate on final follow-up, if residual stones remain.

Böbrek taşlarına uygulanan fleksibl üreterorenoskopi sonrası stent yerleştirilmesi son takipte taşsızlık oranını arttırabilir: Retrospektif tek merkezli çalışma

Abstract

Amaç: Her ne kadar üreteroskopik
cerrahi sonrası üreteral çift J uçlu (Double J-D/J) stent yerleştirilmesinin
postoperatif ağrıyı azaltmaktaki avantajı gösterilmiş olsa da taşların
temizlenmesi ve ek işlem için hasta uyumuna etkisi tam
olarak değerlendirilmemiştir. Biz bu çalışmada stent takılmasının ek tedaviler
sonunda taşsızlık oranlarına olan etkisini araştırdık.

Yöntem: Kasım 2009 ve
Ocak 2015 tarihleri arasında fleksibl üreterorenoskopi (FURS) uygulanan
hastaların tıbbi kayıtları gözden geçirildi. Maling üreteral darlık, ileri
derecede iskelet malformasyonu, böbrek malformasyonu olan hastalar ve takipten
çıkan hastalar çalışmadan çıkarıldı. 289 hastanın 47’si (24 stent takılan, 23
stent takılmayan) değerlendirilmeye alındı. Operasyon sırasında D/J stent
takılan (grup 1) ve takılmayan (grup 2) hastaların perioperatif ve postoperatif
parametreleri ve taşsızlık oranları karşılaştırıldı.

Bulgular: Gruplar
arasında yaş, cinsiyet, vücut kitle indeksi, operasyon öyküsü, operasyon öncesi
stent yerleştirilmesi, şok dalga litotripsi hikayesi, üreteral darlık, taş
boyutu, akses kılıfı kullanım oranı, tekrar tedavi, ek tedavi taş sayısı ve
lokalizasyonu açısından fark yoktu. Stent uygulanan grupta anlamlı olarak
operasyon süresi uzun izlendi. Ek tedavileri red etme oranı grup 1’de daha
düşük izlendi. İlk ay sonunda taşsızlık oranları iki grup için benzer olmasına
rağmen, ek tedavilerden sonra taşsızlık oranları grup 1’de anlamlı olarak
yüksek izlendi.







 Sonuç: FURS sırasında stent yerleştirilmesi,
rezidüel taşların kalması durumunda son takipte taşsızlık oranını
arttırmaktadır.
