Ureterorenoscopy can be successfully and safely applied without the need for ureteral dilatation in ureteral pathologies of children.

Intravesical oxybutynin treatment was observed to be safe; however, a single daily dose of oxybutynin may not be sufficient to increase bladder capacity. Intravesical use of trospium and tolterodine at high doses caused epithelial destruction and diffuse inflammation in the bladder mucosa. The irritation associated with epithelial destruction and inflammation prevented an increase in bladder capacity.

YÖNTEMLER: Ocak 2010 ve Ekim 2013 tarihleri arasında kliniğimizde mini-perkutan nefrolitotomi (PNL) operasyonu uygulanan 44 hastanın dosyaları retrospektif incelendi. Gerekli laboratuar ve radyolojik tetkikler sonrasında cerrahi yapılacak hastalara PNL uygulandı. Operasyon sonrası radyolojik tetkikler ile rezidü taş varlığı araştırıldı. Dört milimetreden büyük rezidü taşlar için takip, ESWL (Ekstra korporeal şok dalga litotripsi) veya tekrar PNL uygulandı. BULGULAR: Mini-PNL yapılmış toplam 44 hastanın 15'i kız, 29'u erkek ve yaş ortalaması 11.5 (3-16) idi. Ortalama taş yükü 435.7 mm2 (150 -900 mm2) olarak saptandı. İşlem sonrasında taşsızlık %84.1, klinik olarak önemsiz taş (<4mm) % 11.36 ve %4.54 ESWL ihtiyacı olabilicek rezidü taş gözlendi. %4.5 hastaya kan transfüzyonu yapıldı. Yedi hastada ameliyat sonrası ateş izlendi. Ameliyat sonrasında bir hastada üretererenoskopi yapılması ve bir hastada da üreteral double j stent takılması ihtiyacı oldu. SONUÇ: Pediatrik PNL operasyonu, ülkemizde genellikle üçüncü basamak sağlık merkezlerinde yapılmasına karşın deneyimli ikinci basamak merkezlerde de yapılabileceği kanaatindeyiz.Anahtar Kelimeler: Çocuk hasta, böbrek taşı, perkutan nefrolitotomi, devlet hastanesi SUMMARY OBJECTIVE: The aim of this study was to evaluate the results of mini-percutaneous stone surgery that performe in a regional state hospital. METHODS:We retrospectively analyzed 44 mini-percutaneous nephrolithotomy (PNL) performed cases that treated at our clinic between January 2010 and August 2013. After necessary laboratory and radiological investigations, we performed PNL for the patients those diagnosed as having stones needed surgery. After surgery, we investigated radiologically whether residual stone fragments remained or not. When there were residual stone fragments (bigger than 4 mm), we performed SWL, repeated percutaneous interventions and surveillance protocols. RESULTS: Of the totally 44 patients (15 girls, 29 boys) underwent mini-PNL at our clinic. The mean age was 11.5 (range: 3-16) and mean stone burden was 435.7 mm2 (range: 150-900). Stone-free rate was 84.1% and the rate of the patients who have residual stones (bigger than 4mm) was 11.36% and SWL was performed 4.54 % patients in the following procedure. Totally only two patients (4.5%) underwent blood tranfusion and postoperative fever was observed 7 patients. Ureterorenoscopy was performed one patient after surgery, the double J stent was replacement in one patient. CONCLUSION: In our country, mini-percutaneous nephrolithotomy in pediatric age group is one of the surgeries which are mostly preferred to be performed in tertiary care centers. Our results supports the idea that this surgery can be performed by experienced surgeons even in secondary care centers.
