Erişkin Böbrek Taşı Hastalarında Daha Minimal İnvazif Perkütan Nefrolitotomi

Amaç: Perkütan nefrolitotomi (PNL) ameliyatı 2 cm’den büyük böbrek taşları için önerilen minimal invazif bir cerrahi işlemdir. Yıllar içinde pediatrik böbrek taşları için geliştirilen minyatürize nefroskoplar artan bir hızla cerrahide mini PNL tanımını alarak uygulanmıştır. Bu çalışmada erişkin hastalara uyguladığımız mPNL operasyonlarının başarı ve sonuçlarını değerlendirdik.Materyal ve Metod: Ocak 2018-Haziran 2020 tarihleri arası hastanemizde 18 yaş üstü erişkin böbrek taşlarına pron pozisyonda uyguladığımız mPNL (20-24f), 42 hasta pre op ve post op özellikleri ile beraber retrospektif olarak değerlendirildi. Hasta özellikleri, operasyon sonrası taşsızlık durumu ve post op komplikasyonlar belirlenerek çalışmaya eklendi.Bulgular: Hastaların yaş ortalaması 33,64±6.8 yıldı. Hastaların 18’inde (%42.8) en az grade 1 hidronefroz mevcuttu. Ortalama taş boyutu 300±26 mm2’di. Üç (%7.1) hastada “staghorn” tipi taş mevcuttu. Ortalama operasyon zamanı 52±18 dk’di. Operasyon sonrası taşsızlık oranı 33 (%78,5) hastada mevcuttu. Post op toplam 3 (%7.1) hastaya ek kan desteği sağlandı. Tüpsüz PNL uygulanmadı. Nefrostomi çıkarılması sonrası akıtma nedeniyle 4 (%9.5) hastaya ve post operatif piyelonefrit tablosu gelişen bir hastaya JJ stent takıldı. Ortalama nefrostomi kalış zamanı 2,5±0,6 gündü.Sonuç: mPNL özellikle pre-post operatif komplikasyonların daha az ve düzeltilebilir olması nedeniyle kanama riski veya operasyon için ko-morbiditesi olan erişkin hastalarda akut obstruksiyonu açmak amaçlı ilk seçeneklerden olabileceğini önermekteyiz.Anahtar kelimeler: PNL, Mini PNL, Böbrek Taşı, Komplikasyon

More Minimally Invasive Percutaneous Nephrolithotomy in Adult Patients with Kidney Stones

Background: Percutaneous nephrolithotomy (PCNL) is a minimally invasive surgical procedure recommended to remove kidney stones larger than 2 cm. Miniaturized nephroscopes developed over the years to treat pediatric kidney stones have been increasingly used in surgeries referred to as mini PCNL (mPCNL). This study will evaluate the success rates and results of mPCNL operations performed on adult patients.Materials and Methods: The study will examine mPCNL (20-24f) performed in the prone position on adults over 18 years old with kidney stones between January 2018 and June 2020. Further, the pre-operative (pre-op) and post-operative (post-op) features of 42 patients were retrospectively evaluated. The patients’ features, including post-op stone-free status and complications, were determined and included in the research.Results: The mean age of the patients was 33.64 ± 6.8 years, and 18 (42.8%) of them had at least grade 1 hydronephrosis. The average stone size was 300 ± 26 mm². Three (7.1%) patients had a "staghorn" type stone. The mean operation time was 52 ± 18 minutes and post-op stone-free rate was present in 33 (78.5%) patients. Additionally, post-op blood transfusions were provided to three (7.1%) patients. Tubeless PCNL was not applied to any patients. After the removal of the nephrostomy tubes, double-J stents were placed in four (9.5%) patients for drainage and in another due to postoperative pyelonephritis. The average length of time a nephrostomy tube was used on patients was 2.5 ± 0.6 days.Conclusions: mPCNL should be one of the first options for resolving ureteral obstructions in adult patients with a high risk of bleeding or co-morbidities from the operation. Thus, it is a more reliable option that can be used to reduce the risk of complications.Key Words: PCNL, Mini PCNL, Kidney Stones, Complications
