Can we predict postoperative fever and urinary tract ınfection after retrograde ıntrarenal surgery? Results of a case control matching multicentric RIRSearch study group.

Purpose: Postoperative fever (POF)/urinary tract infection (UTI) is one of the most unpleasant and undesirable conditions for surgeons after retrograde intrarenal surgery (RIRS). RIRS is not recommended for any patient with a positive urine culture to avoid POF and UTI, but some patients may develop postoperative UTI even if the urine culture is sterile. This study investigated the predictive factors of fever and UTIs after RIRS.

Prognostic Value of Jugular Venous Diameters and Compliance in Patients with Exacerbation of Chronic Obstructive Pulmonary Disease.

Background: Chronic obstructive pulmonary disease (COPD) exacerbations constitute a significant proportion of patients presenting to the emergency department (ED). It has been suggested that measurement of jugular venous diameter and compliance may have prognostic value in patients with heart failure. We hypothesized that these measurements may also be valuable in patients with advanced COPD.

Lower Pole Stones Are Associated with Low Stone-Free Rates in Retrograde Intrarenal Surgery: A Myth or Fact? - A Matched Case-Control Study from the RIRSearch Group.

Introduction: There are conflicting results in the literature regarding the efficacy of retrograde intrarenal surgery (RIRS) in lower pole stones. This study aimed to evaluate RIRS outcomes in lower pole stones by forming matched case-control groups.

Methods: The data of 491 patients who were diagnosed with kidney stones and underwent RIRS were retrospectively included in the study.

The impact of preoperative ureteral stent duration on retrograde intrarenal surgery results: a RIRSearch group study.

A JJ stent placed before retrograde intrarenal surgery (RIRS) may ease the procedure. However, it is important to note that a prolonged duration of double J stent (DJS) placement before RIRS may increase the risk of postoperative urinary tract infection (UTI). Various publications have established this association, although the duration of the DJS before surgery is scarce.
