Article Synopsis
  • A retrospective analysis included 320 patients, revealing a 23.1% complication rate, with a significant difference in CCI scores between patients with multiple complications compared to those with single complications.
  • Findings indicate that the cumulative CCI is a better predictor of hospital stay length and overall complication burden than the noncumulative CCI or CDC, suggesting the CCI is preferable for assessing post-PCNL complications.

Introduction: The prevelance of urinary system stone disease in children is emphasizing the need for minimally invasive treatments to decrease morbidity and recurrence risk. Percutaneous nephrolithotomy (PCNL) has emerged as a preferred approach for pediatric patients with complex stones due to its minimally invasive nature, including miniaturized and vacuum-assisted access sheaths, advanced laser technology and tubeless and outpatient procedures. However, adult scoring systems have proven ineffective in predicting success and complications in pediatric PCNL.

Purpose: It is critical to provide patients with accurate information on potential surgical outcomes during the preoperative phase. Several scoring systems have been developed for this specific purpose. This study aimed to examine the predicted efficacy of scoring systems in patients with isolated lower calyx stones who underwent retrograde intrarenal surgery (RIRS).

Mayo Adhesive Probability (MAP) score was developed as a means to predict the presence of adherent perinephric fat. Our aim was to determine the predictive value of the MAP score on surgical outcomes in patients undergoing standard adult percutaneous nephrolithotomy (PCNL). We retrospectively analyzed the data from 130 renal units that underwent PCNL between January 2022 and 2023.

Background: To compare the effectiveness of spinal anesthesia (SA) and the combination of intraurethral topical instillation of 2% lidocaine + intraurethral local visual injection anesthesia (T + LIA) for visual internal urethrotomy (VIU) in the treatment of traumatic posterior urethral strictures and prostatic urethral stenoses.

Methods: In this study, the results of 178 patients who underwent visual internal urethrotomy for posterior urethral strictures and prostatic urethral stenoses secondary to trauma in our clinic between October 2018 and January 2020 were analyzed retrospectively. Patients were divided into two groups as combined T + LIA (n=146, 82.

Introduction: Fluoroscopy is used for access sheath insertion and postoperative control during retrograde intrarenal surgery (RIRS) operation but with this technique both patient and operation team are exposed to radiation. The use of fluoroscopy is disadvantage for both patient and surgeon. Considering results of recent studies, it is clearly seen that fluoroscopy doesn't affect the success and complication rates of RIRS.

Objective: Urolithiasis prevalence is 2-20% according to different geographic characteristics in different populations. In this study, we aimed to present the distribution of operation numbers for both percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) in terms of age and stone size in order to reveal the changes over the years.

Method: Between January 2010 and March 2016, 1814 patients were operated for the treatment of renal stones.

Article Synopsis
  • The study aimed to identify risk factors for postoperative infections in patients undergoing flexible uretero-renoscopy with laser lithotripsy (FURSLL) and to analyze pathogen resistance from preoperative urine cultures.
  • A total of 492 patients were reviewed, with 8.5% developing infections post-surgery, and 12% showing positive urine cultures, including a notable number of multidrug-resistant (MDR) pathogens.
  • The study concluded that having a positive preoperative MDR urine culture significantly increased the risk of postoperative infections, highlighting the need for more research on MDR infections to improve patient outcomes.

The purpose of this study is to determine the perioperative risk factors for increased blood loss in children undergoing percutaneous nephrolithotomy (PCNL).We retrospectively reviewed the data on pediatric patients who had undergone PCNL for stone disease in our department. Blood loss estimation was quantified by measuring the changes in hematocrit plus the volume of red blood cells transfused.
