Abstract

Objective: We aimed to compare the efficacy and safety of supine mini-percutaneous nephrolithotomy (SMPCNL), retroperitoneal laparoscopic ureterolithotomy (RPUL), and flexible ureterorenoscopy (FURS) in the treatment of impacted proximal ureteral stones larger than 15 mm in diameter.
Material and Methods: Data of the patients who underwent SMPCNL, RPUL, and FURS in our institution for proximal ureteral stones between August 2015 and September 2020 were reviewed. Collected data included age, gender, body mass index (BMI) and hydronephrosis grade, stone density, duration of surgery, hospital stay and recovery period, stone-free and demographic data such as complication rates and duration of surgery.
Results: Overall, 162 patients were included. Of these patients, 52 (32.1%) were in Group 1 (SMPCNL group), 53 (32.7%) were in Group 2 (RPUL group), and 57 (35.2%) ) were in Group 3 (FURS group). Mean operative times were 53±8.2 minutes in Group 1, 63.2±6.6 minutes in Group 2, and 73.7±7.5 minutes in Group 3 (p=0.000). The mean hospital stay was significantly shorter in Group 3 compared to the other groups (p=0.000). The stone-free rates at the initial evaluation were 100%, 90.3%, and 87.7% in the RPUL, SMPCNL, and FURS groups. This rate was significantly lower in the FURS group compared to the other groups (p=0.02).
Conclusion: SMPCNL and RPUL procedures are as safe as FURS in treating patients with proximal ureteral stones larger than 15 mm.

15 milimetreden büyük impakte proksimal üreter taşlarında supin perkütan nefrolitotomi; Fleksible üreterorenoskopi ve retroperitoneal laparoskopik üreterolitotominin karşılaştırılması

Abstract

Amaç: Çapı 15 mm’den büyük gömülü proksimal üreter taşlarının tedavisinde sırtüstü mini-perkütan nefrolitotomi (SMPCNL), retroperitoneal laparoskopik üreterolitotomi (RPUL) ve fleksibl üreterorenoskopinin (FURS) etkinlik ve güvenliğini karşılaştırmayı amaçladık.
Gereç ve Yöntemler: Ağustos 2015-Eylül 2020 tarihleri arasında kurumumuzda proksimal üreter taşı nedeniyle SMPCNL, RPUL ve FURS uygulanan hastaların verileri gözden geçirildi. Toplanan veriler yaş, cinsiyet, vücut kitle indeksi (VKİ) ve hidronefroz derecesi, taş yoğunluğu, ameliyat süresi, hastanede kalış ve iyileşme süresi, komplikasyon oranları ve ameliyat süresi gibi taşsız ve demografik verileri içeriyordu.
Bulgular: Genel olarak 162 hasta dahil edildi. Bu hastaların 52’si (%32,1) Grup 1 (SMPCNL grubu), 53’ü (%32,7) Grup 2 (RPUL grubu), 57’si (%35,2) Grup 3’te (FURS grubu) idi. Ortalama ameliyat süreleri Grup 1’de 53±8.2 dakika, Grup 2’de 63,2±6,6 dakika ve Grup 3’te 73,7±7,5 dakika idi (p=0,000). Ortalama hastanede kalış süresi Grup 3’te diğer gruplara göre anlamlı olarak daha kısaydı (p=0.000). İlk değerlendirmede taşsızlık oranları RPUL, SMPCNL ve FURS gruplarında %100, %90.3 ve %87.7 idi. Bu oran FURS grubunda diğer gruplara göre anlamlı derecede düşüktü (p=0.02).
Sonuç: SMPCNL ve RPUL prosedürleri, proksimal üreter taşları 15 mm’den büyük hastaların tedavisinde FURS kadar güvenlidir.
