RETROGRADE İNTRARENAL CERRAHİ (RIRS): CERRAHİ DENEYİMİMİZ VE KLİNİK SONUÇLARIMIZ

Amaç Üriner sistem taş hastalıkları ülkemizde ve dünyada sık görülmektedir. Flexıble üreterorenoskop (flex URS) ilk defa 1964 yılında Marshall tarafından tanımlanmıştır ve ilerleyen teknoloji ile birlikte 1987 yılında cerrahi teknik olarak kılavuzlarda yerini almıştır. Endikasyonları hızla genişlemektedir. Bu çalışmamızda kliniğimizde retrograde intrarenal cerrahi (RIRS) uygulanan hastaların verileri retrospektif olarak değerlendirilmiştir. Gereç ve Yöntem Mart 2017 ile Ocak 2019 tarihleri arasında Süleyman Demirel Üniversitesi Tıp Fakültesi (SDÜ) üroloji kliniğinde RIRS yapılmış 106 hastanın demografik verileri, taş boyutları, lokalizasyonları, skopi süresi, taşsızlık oranları ve postoperatif komplikasyonlar retrospektif olarak değerlendirildi. İşlem sonrası tüm hastalar 4 hafta sonra direkt üriner sistem grafisi ve bilgisayarlı tomografi görüntüleme yöntemleriyle değerlendirildi. Bulgular RIRS uygulanan 106 hastanın (66 erkek, 40 kadın) ortanca yaşı 52 (23-73) yıl olup, ortalama taş boyutu 13,9 (7-19) mm olarak hesaplandı. Ortalama operasyon ve floroskopi süresi sırayla;74 (30-135) dakika, 62 (20-136) saniyedir. İşlem öncesinde hiçbir hastada DJ kateteri yoktu ancak tüm hastalara işlem sonunda DJ kateteri yerleştirildi ve kateter 4 hafta sonra lokal anestezi altında çekildi. On bir (%10,3) olguda üreter darlığı nedeniyle, 8(%7,5) olguda da rezidü taş nedeniyle 2. seans yapıldı.RIRS yapılan taşların 19 (%17,9) üst kalikste, 9(%8,4) orta kalikste, 40 (%37,7) alt kalikste, 38(%35,8) olguda renalpelviste olduğu değerlendirildi. Hastalarımızın % 82,1’ inde ilk seansta taşsızlık sağlandığı bulundu. İkinci seans sonrası taşsızlık oranı % 92,5 olarak tespit edildi. Hastaların ortalama yatış süreleri 1,5 gün (1-9) gündü. Beş hastada postoperatif dönemde üriner sistem enfeksiyonu gelişti. RIRS uygulanan hastalarda cerrahi ya da cerrahi dışı nedenle mortaliteye rastlanmadı. Sonuç RIRS, taş cerrahisinde etkinlik ve komplikasyonlar açısından güvenilir bir yöntemdir. Özellikle ESWL dirençli taşlarda, obez, kas iskelet deformiteli hastalarda, soliter taşlı böbrekte, gebelikte, kanama diyatezinde önemli cerrahi alternatifitir. Teknolojik ilerlemeler ile birlikte tekniğin avantajları da düşünüldüğünde ilerleyen zamanlarda daha aktif kullanılacağı ve yaygınlaşacağı görüşündeyiz.

RETROGRADE INTRARENAL SURGERY (RIRS): OUR SURGERY EXPERIENCE AND CLINICAL RESULTS

Objective Urinary system stone diseases are common in our country and in the world. The flexible ureterorenoscope (flex URS) was first described by Marshall in 1964 and took its place in the guidelines as a surgical technique in 1987 with the advancing technology. Its indications are expanding rapidly. In this study, the data of patients who underwent retrograde intrarenal surgery (RIRS) in our clinic were evaluated retrospectively. Material and Method Demographic data, stone sizes, localizations, fluoroscopy duration, stone-free rates and postoperative complications of 106 patients who underwent RIRS in the urology clinic of Süleyman Demirel University Faculty of Medicine (SDU) between March 2017 and January 2019 were evaluated retrospectively. After the procedure, all patients were evaluated with direct urınary system graphy and computer tomography imaging methods 4 weeks later. Results The median age of 106 patients (66 males, 40 females) who underwent RIRS was 52 (23-73 years) and the mean stone size was calculated as 13.9 (7-19) mm. The mean duration of operation and fluoroscopy were respectively;74 (30- 135 minutes is 62 (20-136) seconds. None of the patients had a DJ catheter before the procedure, but a DJ catheter was placed in all patients at the end of the procedure and the catheter was removed under local anesthesia 4 weeks later. A second session was performed in 11 (10.3%) cases due to ureteral stenosis and in 8 (7.5%) cases because of residual stones. calyx, 40 (37.7%) lower calyx, 38 (35.8%) cases were found in the renal pelvis. It was found that 82.1% of our patients were stone-free in the first session. After the second session, the stone-free rate was 92.5%. Conclusion RIRS is a reliable method in terms of efficacy and complications in stone surgery. It is an important surgical alternative especially in ESWL resistant stones, obese patients with musculoskeletal deformities, solitary kidney stones, pregnancy and bleeding diathesis. Considering the advantages of the technique together with the technological advances, we think that it will be used more actively and become widespread in the future.
