To compare the outcomes of mini-PCNL (miniaturised percutaneous nephrolithotomy) in prone and supine positions in elderly patients.Cohort study.Department of Urology, University of Health Sciences, Turkey, between April 2017 and January 2021.Patients over 65 years of age were included in the study. All patients' comorbidities were recorded and charlson comorbidity index (CCI) score was calculated. The groups were compared in terms of perioperative values, stone-free rates and complication rates. Logistic regression analysis was used to evaluate risk factors for complication development. Postoperative complications were noted according to the Clavien scoring system (CSS).There were 54 patients in the supine mini-PCNL group and 64 in the prone mini-PCNL group. The median ages were 67 in the prone and 66 in the supine group. CCI scores were similar in both groups (p = 0.735). Stone-free and total complication rates were not statistically different in the groups (p = 0.994 and p = 0.247, respectively). However, grade 1-2 complication rates were significantly higher in the prone group (p=0.020). CCI score and stone size were significantly associated with the development of complications (p = 0.018 and p = 0.034, respectively).The present study is the first to compare the outcomes of mini-PCNL in prone and supine position in geriatric patients. Supine mini-PCNL is a potentially safer alternative treatment method for older patients with high CCI scores. Key Words: Percutaneous nephrolithotomy, Supine position, Elderly, Mini-PCNl, CCI score.

The aim of this study aim is to clarify the relationship between Overactive bladder syndrome (OAB) and severity of lower extremity ischemia by using Fontaine classification system.Patients who were diagnosed with lower extremity arterial disease were enrolled into the study. The Fontaine score of each patient was taken and all patients completed the validated Turkish version of OAB-V8 questionnaire. Body mass index, serum creatinine, blood urea nitrogen, cholesterol and fasting plasma glucose levels were measured. The patients were divided into two groups. Patients with OAB-V8 score above 8 were enrolled into group 1 and patients with OAB-V8 score under 8 were enrolled into group 2.At the end of study period, 181 patients who met the inclusion criteria were enrolled into the study. Patients with OAB ? 8 score (n= 79) were compared with patients with OAB8 score (n= 102). The mean age and the mean BMI were significantly higher in patients with OAB ? 8 (P = .001 and P = .001, respectively). Also, HDL- cholesterol level was found significantly lower in group 1 patients (P= .001). Multivariate regression analysis showed that presence of Fontaine score ? class 2b, age ? 60 years, BMI ? 30 kg/m2 , and HDL-cholesterol levels60 mg/dL were predictive factors for OAB.The present study demonstrated that incidence of OAB is higher in patients with severe lower extremity ischemic symptoms, older age, high BMI, and lower HDL-cholesterol level.

Life expectancy has become longer, thus the number of elderly people who require treatment for nephrolithiasis has increased. We aimed to analyze the efficacy of flexible ureterorenoscopy (f-URS) and miniaturized percutaneous nephrolithotomy (mPNL) in the management of 10 and 30 mm renal stones in patients aged >60 years. In prospective non-randomized series, the data of patients who underwent f-URS or mPNL for kidney stones between July 2013 and July 2016 were analyzed. The procedure was accepted as successful if the patient was achieved complete stone clearance according to CT imaging between 1–3 months postoperatively. In total 60 patients and 58 patients were underwent f-URS and mPNL, respectively. The mean operation time, fluoroscopy time and hospitalization time were significantly shorter for the f-URS (p < 0.001, p < 0.001, p < 0.001, respectively). According to Clavien classification system, complication rates were not significantly different between the groups (p = 0.673). The stone-free rate was 81.7% for the f-URS group and 77.6% for the mPNL group after a single-session procedure (p = 0.747). Calcium oxalate monohydrate stones were the most common stone type in both groups. In multivariate analysis, multiple stones localization was only independent factor to predict complications. Our study had showed that both f-URS and mPNL are effective treatment modalities for 10–30-mm renal stones in elderly patients. Additionally, presence of stones in multiple location was the only predictive factor for complication development. Keywords: Aged, Ureteroscopy, Nephrolithiasis, Lithotripsy, Nephrostomy

To evaluate patients, diagnosed with non-muscle invasive bladder cancer, according to patient specific parameters including hemoglobin level, estimated glomerular filtration rate (eGFR), body mass index (BMI) and cigarette smoking and to identify if any of these parameters matters in terms of recurrence prediction.231 patients who have undergone transurethral resection of the bladder (TURB) between January 2015 and January 2018 and diagnosed with non-muscle invasive bladder cancer (NMIBC) were included. Patient demographic characteristics including age, sex, BMI and cigarette smoking were assessed. Hemoglobin, creatinine and eGFR values were recorded. Follow-up was performed according to the European Association of Urology (EAU) guidelines' recommendations. Recurrence and progression during follow-up were recorded.231 patients were included in the study. Median patient BMI, Hb levels, and eGFR values were 26.51 kg/m2 (IQR 5.48), 14,2 g/dL (IQR 2.50), and 83.25 ml/min/1.73m2 (IQR 27.83), respectively. Among all patients, 105 (45%) were ex-smokers and 78 (33%) were current smokers, 41 had anemia (17.7%), 37 (16%) patients were obese; 104 (45%) had mildly impaired renal function and 34 (14.7%) had impaired renal function. During follow-up, 67 (29%) patients had disease recurrence and 21 (9.1%) had disease progression (9.1%). Univariate and multivariate analyses revealed significant relationship between recurrence and obesity, impaired renal function and cigarette smoking.Recurrence is a commonly encountered unfortunate consequence of NMIBC, and obesity, renal failure, history of smoking and anemia seem to increase the rate of recurrence among bladder cancer patients.
