Hounsfield ünitesi (HU), taş oluşumunu değerlendirmek için en yaygın değer ve aynı zamanda yönetim başarısı için öngörücü bir faktördür. Bu çalışmada, sistemik inflamatuar yanıt belirteçleri kullanarak taşın sertliğini tahmin etmeyi amaçladık. Gereç ve Yöntem: 2015 ve 2020 yılları arasında konvansiyonel perkütan nefrolitotomi uygulanan 192 hastaya (61 kadın ve 131 erkek) ait veri retrospektif olarak gözden geçirildi. Malignite, preoperatif idrar kültürü pozitif olan hastalar çalışma dışı bırakıldı. Hastaların nötrofil lenfosit oranı (NLR), trombosit lenfosit oranı (PLR) ve NCCT'den elde edilen böbrek taşı Hounsfield Ünitesi (HU) verilere kaydedildi.

Objective: The primary aim of this study is to evaluate if severe obesity has any deleterious effect on the early postoperative course in patients undergoing percutaneous nephrolithotomy (PNL) under spinal anesthesia, and the secondary aim is to determine whether severe obesity changes surgical results. Material and Method:The study included 100 patients who underwent a PNL operation for kidney stones of ≥2cm in our clinic. Accordingly, those with BMI <35 kg/m 2 formed the first while the severely obese BMI ≥35 kg/m 2 formed the second group. Age, gender, stone burden, pre/postoperative hemoglobin levels, number and regions of access, duration of surgery, perioperative complications and Visual Analogue Scale score at 24h, PACU admission/ discharge Aldrete scores, and PACU length of stay were recorded.

Introduction In this study we aimed to determine the effects of the 45 degrees sided prone position to the surgeon’s comfort, operation time, fluoroscopy time and complications at the operation of percutaneous nephrolithotomy (PCNL) for the treatment of kidney stone of horseshoe kidney (HK) or rotation anomaly kidney. Material and methods Thirty eight patients (25 male, 13 female) with renal calculi and HK, underwent PCNL. After the amplatz sheath was inserted into the collecting system, the patients in group 1 (n:20) were taken to the 45 degrees side position to the side of the operation and patients in group 2 (n:18) were operated in classical prone position. Operative data of two groups were compared statistically. Results Mean stone size of group 1 was 557.8 ±244.8 mm 3 (188–1175) and group 2 was 590.7 ±172.8 mm 3 (423–909) (p = 0.639). In group 1 mean operation time was 78.6 ±21.8 (45–120) minutes and in group 2 was 95.05 ±11.5 (69–120) minutes. The difference for operation time was statistically significant and shorter in the sided group (p = 0.02). Conclusions The working position of rigid nephroscope is 90 degrees to the body after the dorsomedial or dorsolateral access. In our study the position of patient is laterally sided 45 degree and the flexion on the surgeon’s shoulder was minimised. This new position described for PCNL in HK allows comfortable working position for surgeon after upper pole posterior calyces access.
