Abstract

Amaç
Üroloji kılavuzlarında 10-20 mm arası alt pol taşlarında
özellikle ekstrakorporal şok dalga litotripsi
(SWL)'nin başarısız olduğu veya SWL'nin uygun olmadığı
durumlarda endoürolojik tedaviler olan perkütan
nefrolitotomi (PCNL) ve retrograd intrarenal cerrahi
(RİRC) önerilmektedir. Bu çalışmada 10-20 mm
arası alt pol taşlarında RİRC ile mini perkütan nefrolitotomi
(m-PCNL) uygulanan hastaların sonuçlarını
karşılaştırdık.
Gereç ve Yöntem
2020 ile 2022 yılları arasında 10-20 mm arası alt pol
böbrek taşı nedeniyle endoürolojik tedavi (RİRC veya
m-PCNL) uygulanan 116’sı RİRC, 71’i m-PCNL olan
toplam 187 hastanın dosyaları retrospektif olarak incelendi.
Preoperatif yanlılıkları önlemek için 1:1 oranı
temel alınarak eğilim skoru eşleştirmesi (propensity
score-match) uygulandı. Analiz sonucuna göre RİRC
uygulanan 65 hasta ve m-PCNL uygulanan 65 hasta
çalışmaya dahil edildi. İki grup arasında intraoperatif
(operasyon süresi, floroskopi süresi) ve postoperatif
bulgular (hastane yatış süresi, hematokrit düşüşü,
taşsızlık oranları ve komplikasyonlar) karşılaştırıldı.
Operasyon sonrası 4 mm veya daha büyük taş
saptanması klinik anlamlı rezidü olarak tanımlandı.
Komplikasyonlar Clavien skorlama sistemine göre ve
intraoperatif-postoperatif olarak sınıflandırıldı.
Bulgular
Her iki grup, demografik özellikler (yaş, cinsiyet, vücut
kitle indeksi), radyografik taş karakteristikleri (taş
boyutu, taş lateralitesi, taş opasitesi, ve taş dansitesi)
açısından karşılaştırıldığında istatistiksel olarak anlamlı
fark gözlenmedi. Operasyon süresi, floroskopi
süresi, hastane yatış süresi açısından gruplar karşı-
laştırıldığında, RİRC grubunda bu süreler istatistiksel
olarak anlamlı derecede daha kısaydı (p<0.001). Ayrıca
RİRC grubunda hematokrit miktarındaki düşüş
m-PCNL grubuna göre istatistiksel olarak anlamlı
derecede daha azdı (p<0.001). Postoperatif taşsızlık
oranları ile intraoperatif ve postoperatif komplikasyon
oranlarına bakıldığında her iki gruptaki sonuçların
benzer olduğu görüldü.
Sonuç
RİRC operasyonu 10-20 mm arası alt pol böbrek taşlarında
m-PCNL operasyonu ile benzer taşsızlık ve
komplikasyon oranlarına sahip olan etkili ve başarılı
bir endoürolojik tedavi alternatifidir. Bununla birlikte
RİRC operasyonunun m-PCNL operasyonuna göre
daha kısa operasyon, floroskopi ve hastane yatış sürelerine
sahip olması ile daha az kan kaybına neden
olması daha güvenilir şekilde uygulanabileceğini göstermektedir.

RETROGRADE INTRARENAL SURGERY VS MINI-PERCUTANEUS NEPHROLITHOTOMY IN THE MANAGEMENT OF 10-20 MM LOWER POLE KIDNEY STONES: A PROPENSITY MATCHED ANALYSIS

Abstract

Objective
In urology guidelines, endourological treatments
such as percutaneous nephrolithotomy (PCNL)
and retrograde intrarenal surgery (RIRS) are
recommended for lower pole stones with a diameter of
10-20 mm, especially in cases where extracorporeal
shock wave lithotripsy (SWL) fails or SWL is not
appropriate. In this study, we compared the results of
patients who underwent RIRS and mini percutaneous
nephrolithotomy (m-PCNL) for lower pole stones with
a diameter of 10-20 mm.
Material and Method
The data of 187 patients (116 RIRS, 71 m-PCNL)
who underwent endourological treatment (RIRS or
m-PCNL) for 10-20 mm lower pole kidney stones
between 2020 and 2022 were retrospectively
analyzed. To avoid preoperative biases, propensity
score-matching was applied based on a 1:1 ratio.
According to the results of the analysis, 65 patients
who underwent RIRS and 65 patients who underwent
m-PCNL were included in the study. Intraoperative
(operation time, fluoroscopy time) and postoperative
findings (hospitalization time, drop in hematocrit,
stone-free rates, and complications) were compared
between the two groups. Postoperative stone
detection of 4 mm or larger was defined as clinically
significant residue. Complications were classified
according to the Clavien scoring system and as
intraoperative-postoperative.
Results
When the two groups were compared in terms of
demographic characteristics (age, gender, body
mass index) and radiographic stone characteristics
(stone size, stone laterality, stone opacity, and stone
density), no statistically significant difference was
observed. When the groups were compared in terms
of operation time, fluoroscopy time and hospitalization
time, these periods were statistically significantly
shorter in the RIRS group (p<0.001). In addition, the
decrease in the amount of hematocrit in the RIRS
group was significantly less than in the m-PCNL group
(p<0.001). When the postoperative stone-free rates
and intraoperative and postoperative complication
rates were examined, it was seen that the results in
both groups were similar.
Conclusion
RIRS operation is an effective and successful
endourological treatment alternative with stonefree
rates and complication rates similar to m-PCNL
operation in lower pole kidney stones between 10-20
mm. However, the fact that the RIRS operation has
shorter operation, fluoroscopy and hospitalization
times compared to the m-PCNL operation and causes
less blood loss shows that it can be applied more
reliably.
