[Preoperative double J stent placement in the endoscopic treatment of ureteral and renal Stone: A multicenter, national study.].

Objective: Aim of our study was to evaluate the effectiveness and safety of the preoperative placement of JJ stent compared to not doing in patients undergoing ureteroscopy for ureteral and kidney stone.

Materials And Methods: Prospective, observational, multicenter study. Adult patients, who underwent ureteroscopy treatment for ureteral and kidney stone, were recruited from August 2017 to March 2019, in 23 Argentine institutions.

Comparison of GreenLight laser and transurethral resection of the prostate baseline characteristics and outcomes: lessons learned from the Clinical Research Office of the Endourological Society GreenLight Laser Study.

Background: To compare baseline characteristics and outcomes of patients undergoing GreenLight laser vaporization (GL) or transurethral resection of the prostate (TURP) in a real life setting.

Methods: In this prospective observational cohort, the Clinical Research Office of the Endourological Society (CROES) collected data of consecutive GL or TURP treated patients. Treatment involved one of three GL laser powers (80 W, 120 W or 180 W) based on availability in each participating centre, or TURP.

Postoperative infection rates in patients with a negative baseline urine culture undergoing ureteroscopic stone removal: a matched case-control analysis on antibiotic prophylaxis from the CROES URS global study.

Purpose: To examine the effects of antibiotic prophylaxis on postoperative infection rate in patients with negative urine cultures undergoing ureteroscopy (URS).

Patients And Methods: Using the Clinical Research Office of the Endourological Society (CROES) URS Global Study database, patients with a negative baseline urine culture undergoing URS for ureteral stones (n=1141) or kidney stones (n=184) not receiving antibiotic prophylaxis were matched with those who were predefined by risk factors, including gender, American Society of Anesthesiologists (ASA) score, and ureteral stent placement. Patient characteristics, operative data, and postoperative outcomes, including the development of urinary tract infection (UTI) and fever, in the two groups were compared.

Outpatient simultaneous treatment of benign prostatic hyperplasia and bladder lithiasis with GreenLight™ and holmium laser.

Purpose: To evaluate our experience in the combined treatment of benign prostatic hyperplasia (BPH) and bladder lithiasis with GreenLight(™) and holmium laser, respectively, on an outpatient basis.

Patients And Methods: From August 2006 to May 2009, 20 patients with prostatic hyperplasia and bladder lithiasis were treated. First, the lithiasis was treated, and then the GreenLight laser vaporization of the prostate was performed, both at the same surgical time and under general anesthesia.
