PNL ve açık böbrek taşı cerrahisi sonrası rekürrens

Abstract

Amaç: Nefrolitiazis nedeniyle perkütan nefrolitotripsi PNL veya açık cerrahi geçiren hastalarda taş rekürrens oranını karşılaştırmak.Gereç ve Yöntemler: Ocak 2006-Mayıs 2009 tarihleri arasında cerrahi tedavi uygulanan böbrek taşı tanılı hasta geriye dönük olarak incelendi. Toplam 38 hasta çalışmaya alındı . Grup 1 n:20 hastaya açık cerrahi uygulanırken Grup 2 n:18 hastaya ise PNL uygulandı. Cerrahi sonrası non-opak ve rezidü taşı olan hastalar çalışma dışı bırakıldı. Taş taraması için idrar analizi, radyografi ve non-kontrast bilgisayarlı tomografi yapıldı. Hastaların yaş, cinsiyet, hastanede kalış süresi, preoperatif taş yükü, postoperatif takip süresi ve postoperatif taş yükü kaydedildi.Bulgular: Grup 1 ve grup 2 deki erkek / kadın oranı sırasıyla 11/9 ve 10/8 dir. Yaş ortalaması 1. grupta 41,9 ± 13,58 ve 2. grupta 36,22 ± 14,3 yıl idi. Ameliyat öncesi taş yükü PNL grubunda 329,46 ± 249,66 mm2 iken açık cerrahi grubunda 390,72 ± 200,12 mm² idi. Taş rekürrensi açık cerrahi grubunda sadece % 20 iken PNL grubunda % 61olarak saptandı. Ameliyat sonrası kontrollerde taş yükü Grup 2’de Grup 1’e nazaran anlamlı derecede daha yüksek bulundu p= 0.40 . Sonuç: PNL son zamanlarda böbrek taşı ameliyatları için daha sık kullanılır olmuştur. Taş nüks oranı rezidüel fragmanlar nedeniyle perkütan nefrolitotripsi sonrası artabilir

Recurrence after PNL and open renal stone surgery

Abstract

Objective: To compare the rate of stone recurrence in patients who underwent percutaneous nephrolithotripsy PNL or open surgery because of nephrolithiasis. Material and Methods: Between January 2006-May 2009 with diagnosis of nephrolithiasis who underwent surgical treatment were reviewed retrospectively. Totally 38 patients were included to study. Group 1 n: 20 underwent open surgery, while Group 2 n: 18 patients underwent PNL. The patients whom have nonopaque and residual stones after surgery were excluded from the study. By the controls urine analysis, plain radiography and non-contrast computer tomography were performed for screening stones. Patients’ age, gender, duration of hospital stay, preoperative stone burden, postoperative follow-up period and postoperative stone burden were recorded. Results: The ratio of male/female in group 1 and group 2 is 11/9 and 10/8 respectively. The mean age was 41,9±13,58 in group 1 and 36,22±14,3 years in group 2. Preoperative stone burden was 329,46±249,66mm2 in PNL group while 390,72±200,12mm2 in open surgery group. Stone recurrence was detected in 61 % 11/18 of the patients treated with PNL, while only in 20 % 4/20 of the patients in the open surgery group. Postoperative control stone burden was significantly higher in group 2 than in group 1 p=0.40 . Conclusion: PNL has been used more frequently for renal stone surgeries recently. The stone recurrence rate may increase after percutaneous nephrolithotripsy due to insignificant residual fragments
