“…In our multiple‐tract group, S.T.O.N.E. score was significantly higher compared to patients who received single‐tract PNL, providing once more evidence that nephrolithometry scores by including both stone burden and the patient's anatomy, including number of affected calyces and tract length, appear to be valid tools in indicating the complexity to achieve full percutaneous stone clearance 28,29 . Interestingly, our data demonstrated a significant predominance of female patients in the multiple‐tract group (1.2:1.0) although gender distribution female‐to‐male of the whole cohort was 1.0:1.8.…”

Introduction: To investigate the efficacy and safety of multi-tract percutaneous nephrolithotomy (PNL) against the benchmark of the single-tract approach.Methods: A retrospective analysis of 391 consecutive PNL procedures was conducted in our tertiary referral center between April 2016 and March 2020. Clinical outcome parameters such as stone-free rate, operation time, postoperative complications according to Clavien-Dindo, length of hospital stay and time to ipsilateral recurrence resulting in active treatment were assessed.Results: Multi-tract PNL and single-tract PNL were performed in 37 (9%) and 354 (91%) cases respectively. At baseline, compared to single-tract PNL, multitract PNL cases were characterized by significantly larger stone burden (2.62 vs 0.97 cm 3 , P < .00), lower Hounsfield units (HU) (751 vs 1017 HU, P < .01), a more complex S.T.O.N.E. (size, tract length, obstruction, number of calyces, essence) score (P < .00) and a higher rate of high-risk stone formers (59 vs 19%, P < .00). Analysis of outcome revealed shorter operation time and length of hospital stay for single-tract PNL compared to multi-tract PNL (P < .01). How-

Upper urinary tract stones are among the most common diseases in daily urology practice. The treatment method is determined based on the location, size and density of the stone. 1 Extracorporeal Shock Wave Lithotripsy (ESWL) and Retrograde Intrarenal Surgery (RIRS) are the popular treatment methods for pelvis and proximal ureteral stones smaller than 2 cm in size. For lower pole stones, follow-up is recommended in asymptomatic cases while ESWL is the primary treatment method for symptomatic patients. In stone treatment, the

“…To the best of our knowledge, nomograms have been widely used in clinical studies [21,22]. A recent study by Gao et al [10] has investigated the predictors of sepsis among patients with struvite stones and performed the nomogram based on the calculated scores of some related factors (preoperative serum creatinine and multidrug resistance) to predict the probability of sepsis.…”

Introduction. To describe the clinical parameters of urinary stones and investigate the preoperative predictors of sepsis in patients following percutaneous nephrolithotomy (PCNL). Patients and Methods. A retrospective study of patients who underwent PCNL between August 2017 and December 2019 was performed. The patients were divided into the sepsis and nonsepsis groups according to whether they had sepsis, and their data were compared for further analysis. Results. Fifteen (6.1%) patients matching in age, gender, body mass index (BMI), and the number of access variables were included in the sepsis group. The multivariate analysis demonstrated that the staghorn calculi (OR: 12.206, P < 0.001 ) and positive midstream urine culture (OR: 16.505, P < 0.001 ) were independent risk factors of sepsis, while preoperative renal fistula (OR: 0.122, P < 0.001 ) was a protective factor of sepsis. The three factors were ultimately selected to develop a nomogram to predict the probability of sepsis. The new nomogram was well calibrated and had higher diagnostic accuracy (the area under the curve: 0.916). Conclusions. Our study reveals that patients with complex stones and positive bacteriuria are associated with a significantly high risk of sepsis after surgery. The removal of obstruction before operation under certain conditions might be a reliable protective factor of sepsis.
