RESUMEN
ABSTRACT Purpose: We aimed to compare the success and complication rates of the anterograde and retrograde Ureterorenoscopy (URS) for impacted upper ureteral stones in patients > 65 years of age. Materials and Methods: Data of 146 patients >65 years of age and underwent anterograde URS (n=68) in supine position or retrograde URS (n=78) for upper ureteral impacted stones>10 mm between January 2014 and September 2018 were collected prospectively. The groups were compared for success and complication rates, duration of operation, hospital stay, and ancillary procedures. Results: Anterograde and retrograde URS groups were similar for demographic and stone related characteristics. The success rate of the anterograde URS group was significantly higher than the retrograde URS group (97.1% vs. 78.2%, p=0.0007). The complication rates were similar for the two groups (p=0.86). Clavien grade I and II complications were observed in 3 patients in each group. The mean hemoglobin drop was 0.5 g/dL in the anterograde URS group and blood transfusion was not performed in any of the patients. The mean duration of operation was 41.2±12.5 minutes in the mini-PNL group and 59.6±15.1 minutes in the RIRS group and the difference was statistically significant (p=0.02). The median duration of hospitalization was 1 day for both groups. Conclusions: Performing anterograde URS in supine position provided better success rates and similar complication rates compared to retrograde URS. Based on these results anterograde URS shall be considered as one of the primary treatment options for management of impacted upper ureteral stones in the elderly population.

ABSTRACT Objectives To evaluate the efficacy of a novel decision aid (DA) in improving the patients' level of knowledge and decreasing decisional conflicts while deciding for SWL vs. RIRS in case of a symptomatic renal stone <2 cm. Materials and Methods In this prospective randomized study patients were randomized to receive either standard informing process (group 1, n=57) or DA (group 2, n=58). Level of knowledge was assessed with a questionnaire of 10 questions before and after patient informing process. Level of decisional conflict was assessed with a previously validated scoring system. Logistic regression analysis was performed to identify factors associated with adequate level of knowledge. Results Level of knowledge increased significantly in both groups after patient informing process. The increase was significantly more prominent in group 2 (p=0.045). Percentage of patients with adequate knowledge was also higher in group 2 (56.1%vs.74.1%, p=0.04). Mean decisional conflict scale score (higher score indicates higher decisional conflict level) was also significantly higher in group1 (14.7±14.5 vs. 10.1±13.7, p=0.045). Multivariate logistic regression analysis revealed higher education level (college degree) and use of DA as factors associated with adequate level of knowledge. Conclusions In the current study, The DA was shown to have a positive impact on level of knowledge and diminish the level of decisional conflict for patients with a symptomatic non-lower pole renal stone <20 mm. We recommend development and use of DAs for particular clinic scenarios to aid in education of patients and shared decision making process in stone disease clinics.

OBJECTIVE: Compare clinical outcomes in patients having urothelial tumors invading less than one half of the depth of bladder muscle and greater than one half of bladder muscle and, to determine various clinical variables as predictive factors for survival. MATERIALS AND METHODS: According to our inclusion criteria, 57 patients among cases with T2 bladder tumor were selected. Thirty-five patients (61.4 percent) had pT2a (Group-1) and 22 patients (38.6 percent) had pT2b (Group-2) muscle invasive tumors. Mean follow up time was 7.3 years for Group-1, and 6.1 years for Group-2. Multivariate analysis was performed in order to identify possible correlation of clinical variables like age, gender, grade of primary tumor, appearance of local and/ or distant metastasis with patient outcome. RESULTS: Five year recurrence-free and overall survival rates were 69.1 percent and 44.3 percent for patients with pT2a tumor, whereas these ratios were 66.1 percent and 43 percent, respectively for patients with pT2b tumor (p = 0.896; p = 0.975). Mean overall and progression-free survival times were 87.7 ± 13.8 and 116 ± 13.12 months for Group-1, while they were 73.8 ± 13.7 and 88.85 ± 12.55 months for Group-2, respectively. On both univariate and multivariate analysis, age was noticed as an independent predictive factor for survival. CONCLUSIONS: The depth of muscle invasion in bladder tumors has no prognostic significance. Recurrence of the disease either locally or at distant sites dramatically shortens patients' life. Being older than 60 years old during the time of radical surgery, is also a bad prognostic factor for overall and progression-free survival.
