Objective: Our study aimed to evaluate the impact of bacillus Calmette-Guérin shortage on recurrence and progression in patients with non-muscle invasive bladder cancer in a Brazilian cohort.
Methods: We retrospectively reviewed the clinicopathological data of 409 patients who had their first transurethral resection of the bladder tumor for intermediate or high-risk non-muscle invasive bladder cancer between June 2014 and May 2021 in a tertiary public hospital in Brazil. Patients included had non-muscle-invasive urothelial carcinoma of the bladder resected completely for the first time, regardless of bacillus Calmette-Guérin use.
Objective: The aim of this study was to identify predictive factors for complications after percutaneous nephrolithotomy.
Methods: We prospectively analyzed patients who underwent percutaneous nephrolithotomy from June 2011 to October 2018. The association of preoperative and intraoperative factors with the presence of complications was assessed using univariate and multivariate analyses.
Objective: The aim of this study was to evaluate the predictive factors for success following percutaneous nephrolithotomy in the supine position.
Methods: Patients who underwent percutaneous nephrolithotomy in the supine position from June 2011 to October 2018 were evaluated. Age, sex, body mass index, the American Society of Anesthesiologists physical status classification, hemoglobin level, number of previous surgeries, stone size, and the Guy's Stone Score were analyzed.
Background: Endoscopic combined intrarenal surgery (ECIRS) has been used to treat complex kidney stones (1). The combined use of ultrasound (US) has the potential to improve safety and reduce radiation exposure, however, it is still underutilized (2).
Objectives: Our objective is to describe, in a step-by-step manner, the ultrasound-guided ECIRS (USG ECIRS) technique, in order to facilitate learning by urologists.
