There is evidence that inflammation response biomarkers are positivity associated with bacteremia and urosepsis. The objective of this study was to investigate the value of preoperative systemic immune-inflammation (SII) in predicting systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL). Records from 365 consecutive patients who previously received standard PCNL for kidney stones were retrospectively reviewed. ⋯ Receiver operating characteristic curve analysis indicated SII for predicting the occurrence of SIRS with a higher AUC (0.782) than other systemic inflammation biomarkers such as LMR (0.734), NLR (0.671), and PLR (0.617). As a novel integrated inflammation biomarker for predicting SIRS after PCNL, SII showed a better predictive value than other traditional inflammation indicators. To our knowledge, we present the first study to investigate the predictive value of the preoperative SII on post-PCNL SIRS.

Stone disease is a unique condition that requires appropriate management in a timely manner as it can result in both emergent conditions and long term effects on kidney functions. In this study it is aimed to identify the up-to-date practice patterns related to preoperative evaluation and anesthesia for stone disease interventions during COVID-19 pandemic. The data of 473 patients from 11 centers in 5 different countries underwent interventions for urinary stones during the Covid-19 pandemic was collected and analyzed retrospectively. ⋯ There is significant alteration in anesthesia methods and interventions. The optimal methods for preoperative evaluation are still unknown and there is discordance between different centers. It takes 21 days for hospitals and surgeons to adapt and develop new strategies for preoperative evaluation and management of stones.

Randomized Controlled Trial Comparative Study
Intracutaneous sterile water injection for pain relief during extracorporeal shock wave lithotripsy: comparison with diclofenac sodium.
Various analgesic applications can be used during extracorporeal shock wave lithotripsy (SWL) for pain relief and maximal success rate. Intracutaneous sterile water injection (ISWI) has been shown to be effective in several types of pain, but a gap exists about its use during SWL. In this paper, we aimed to evaluate the effect of ISWI during SWL and compare that with diclofenac sodium injection used commonly to provide ideal patient contentment. ⋯ The characteristics of the patients and shockwave therapy did not differ significantly between the two groups. Although the mean VAS scores prior to SWL and at every voltage increment during the procedure did not differ, more patients in the diclofenac sodium injection group required rescue analgesia with significantly greater side effects. ISWI is found to be as effective as the diclofenac sodium injection for pain management during SWL with lower adverse event rates.

To assess the safety and efficacy of super-mini percutaneous nephrolithotomy (SMP) in the treatment of symptomatic lower pole renal stones (LPSs) after the failure of shockwave lithotripsy (SWL) or retrograde intrarenal surgery (RIRS), we retrospectively evaluated 44 patients with symptomatic LPSs with previously failed SWL or RIRS and consequently underwent SMP from October 2014 to March 2016. The percutaneous renal access was performed 12-14F with C-arm fluoroscopy or ultrasonographic guidance. Stone disintegration was performed using either Holmium laser or pneumatic lithotripter. ⋯ Clinically insignificant residual fragments were observed in three (6.8%) patients and only one (2.3%) patient had a 6 mm residual calculus. A total of three minor complications (urinary tract infection, hemorrhage resolved by hemostatics and renal colic requiring analgesics) were observed postoperatively. For symptomatic LPSs after the failure of SWL or RIRS, SMP is a safe and efficient auxiliary option and even might be an alternative to SWL or RIRS, while further considering the stone-free rates and stone-related events.

Comparative Study
Emergent versus delayed lithotripsy for obstructing ureteral stones: a cumulative analysis of comparative studies.
To analyze the current evidence on the use of ureteroscopy (URS) and extracorporeal shock wave lithotripsy (ESWL) for the management of obstructing ureteral stones in emergent setting. ⋯ Emergent lithotripsy, either ureteroscopic or extracorporeal, can be offered as an effective and safe treatment for patients with symptomatic ureteral stone. If amenable to ESWL, based on stone and patient characteristics, an emergent approach should be strongly considered. Ureteroscopy in the emergent setting is mostly reserved for distally located stones. The implementation of these therapeutic approaches is likely to be dictated by their availability.
