Introduction: Urinary tract infection involves mortality rate when combined with ureteral obstruction. Lithotripsy has been contraindicated; however, it has been shown to be safe in selected situations. No specific criteria have been widely accepted to indicate which patients are suitable for definitive treatment.

Introduction: We aim to publish our innovative modified biplanar 0-90 endoscopic guided puncture technique for percutaneous nephrolithotomy in supine recorded with a GoPro® camera for standardization of the technique. It solves drawbacks of the fluoroscopic technique, i.e.

Retrograde intrarenal surgery (RIRS) has emerged as the treatment of choice for small to medium stones. We present a case of delayed hemorrhage due to an arteriocaliceal fistula.

The information provided through this project must be assessed and criticized by the physician responsible for the conduct that will be adopted, depending on the conditions and the clinical status of each patient.

Materials And Methods: An electronic questionnaire was sent by email to the 4,745 members of the Brazilian Urological Society (BSU) in 2016 to collect information on the 3 main endourological procedures used in the treatment of nephrolithiasis: Semi-rigid ureteroscopy (URS), Flexible ureteroscopy (F-URS) and percutaneous nephrolithotripsy (PCNL).
Results: A total of 1,267 urologists answered the questionnaire.

Methods: A 13-question e-mail questionnaire was sent to 4,526 Brazilian urologists; the questions addressed demographic characteristics, radiation exposure, and the utilization of shielding devices and dosimeters. The reasons why these devices were not used were also investigated.
Objectives: To identify risk factors associated with hemorrhage during laparoscopic partial nephrectomy (LPN), and to determine the impact of hemorrhage on hospital course.
Methods: We retrospectively analyzed prospective data from 335 LPNs to identify clinicopathologic factors associated with hemorrhagic complications (blood loss requiring ≥ 1 U transfusion) and extended length of hospitalization (≥ 3 days). We excluded patients with a coagulopathy or perioperative vascular injuries.
Objectives: To define the role of crossing vessels in the pathophysiology of ureteropelvic junction (UPJ) obstruction, we analyzed the relationship between the presence of crossing vessels and UPJ pathologic findings in patients undergoing laparoscopic pyeloplasty. The significance of crossing renal vessels in patients with UPJ obstruction is unclear.
Methods: We performed a retrospective analysis of 155 consecutive patients undergoing laparoscopic pyeloplasty.
Purpose: We describe the use of a novel bipolar radiofrequency (RF) system for the destruction of prostate tissue in an ex vivo model.
Materials And Methods: A bipolar RF delivery system (Trod Medical, France) was linked to a 500 kHz generator. Eight lesions were created in an ex vivo bull prostate model using 7-mm (n = 4) and 10-mm probes (n = 4).
Aim: To evaluate percutaneous cryotherapy as a primary treatment option for prostate cancer, comparing different risk groups.
Patients And Methods: Forty-seven prostate cryoablation procedures were performed on 44 patients. Patients median age was 70.
Complex ureteral reconstruction has been performed with ileum, appendix, or other intestinal segments for the treatment of long ureteral strictures. In the past decade, challenging ureteral reconstruction has been approached using laparoscopic urology. We report the case of a 6-cm iatrogenic stricture after treatment of stone disease.

We determined the frequency of postoperative hemorrhage requiring selective angioembolization (sae), the efficacy of this approach, and characterized the angiographic findings.
Methods: We reviewed our database of 4695 patients who underwent percutaneous renal surgery and identified patients requiring SAE for postoperative hemorrhage.
Objectives: To present our experience performing laparoscopic partial nephrectomy (LPN) for hilar renal tumors and demonstrate the feasibility and short-term oncologic efficacy.
Methods: The patients who had undergone LPN for excision of a hilar tumor, defined as a renal tumor that came in direct contact with the renal artery and/or vein, were identified. The clinicopathologic parameters, perioperative course, complications, and oncologic outcomes were analyzed.
Purpose: To evaluate percutaneous cryotherapy as a primary treatment option for high-risk prostate cancer patients.
Patients And Methods: From October 2000 to February 2005, 21 high-risk (Gleason e.8 and/or PSA > 10 and/or stage > T2a) prostate cancer patients underwent 24 percutaneous prostate cryoablation procedures.
