Prognostic factors for the safety and efficacy of retrograde laser lithotripsy: Data from a contemporary series of 155 consecutive patients with single and multiple lithiasis of the urinary tract.

Treatment of large and multiple stones located in the ureter and/or the kidney may be challenging. The aim of the current study was to evaluate the results and complications of retrograde endoscopic lithotripsy for stones located in the urinary tract and to determine prognostic factors for treatment outcome. From April 2017 to March 2020, eligible patients for the active treatment of ureterolithiasis with or without concomitant nephrolithiasis <20 mm were enrolled in the study.

Feasibility of a single session retrograde endoscopic laser lithotripsy of two large stones located in a bifid urinary tract. Presentation of a rare case.

A 76 year-old male presented with urosepsis and acute renal injury secondary to obstruction by a 13 mm stone located in the common segment of a bifid left ureter. A second 10 mm stone was detected in the mid calyx of the lower moiety of the kidney. Drainage of both moieties with two double-J stents was initially performed.

Clinical Outcome and Prognostic Factors of Sepsis, Septic Shock and Prolonged Hospitalization, of Patients Presented with Acute Obstructive Pyelonephritis.

To investigate prognostic factors of outcome of acute obstructive pyelonephritis (AOP). Patients with AOP were prospectively evaluated and logistic regression analysis was applied to identify factors associated with the duration of hospital stay and occurrence of sepsis and septic shock. Based on CT scan findings, 62 patients were found to have AOP and subjected to emergency drainage.
