PCNL showed the highest success and stone-free rate in the surgical treatment of renal stones. In contrast, SWL had the lowest success and stone-free rate.

We investigated whether stone heterogeneity index (SHI), which a proxy of such variations, was defined as the standard deviation of a Hounsfield unit (HU) on non-contrast computed tomography (NCCT), can be a novel predictor for shock-wave lithotripsy (SWL) outcomes in patients with ureteral stones. Medical records were obtained from the consecutive database of 1,519 patients who underwent the first session of SWL for urinary stones between 2005 and 2013. Ultimately, 604 patients with radiopaque

Photodynamic therapy with Radachlorin is a safe, effective treatment for nonmuscle invasive bladder cancer refractory or intolerant to bacillus Calmette-Guérin therapy in select patients.

The recurrence rate of some bladder cancers can be decreased by the implementation of either PDD- and NBI-assisted TUR; in real settings, clinicians should consider replacing WLC as the standard imaging technology to guide TUR.

RIRS can be a safe and effective procedure for selected patients with large renal stones. However, in this meta-analysis, the postoperative stone-free rate of PCNL was higher than that of RIRS in patients with >2 cm renal stones.

Background and objectives: To perform a updated systematic review and meta-analysis comparing effectiveness of percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), and extracorporeal shock wave lithotripsy (ESWL) for treatment of renal stones (RS). Materials and Methods: A total of 37 studies were included in this systematic review and meta-analysis about effectiveness to treat RS. Endpoints were stone-free rates (SFR), incidence of auxiliary procedure, retreatment, and com

Intermediate- and low-frequency SWL have better treatment outcomes than high-frequency SWL when considering both efficacy and complication.

OBJECTIVES: To investigate the incidence of lymphocele and determine the risk factors for postoperative lymphocele after extraperitoneal robot-assisted radical prostatectomy by using propensity score-matching. METHODS: A total of 483 patients underwent extraperitoneal robot-assisted radical prostatectomy for prostate cancer between January 2009 and August 2011. Of these, 200 patients underwent pelvic lymph node dissection during robot-assisted radical prostatectomy. All patients underwent magnet

A common-gate (CG) low-noise amplifier (LNA) that uses the current-reuse technique and is intended to achieve both ultra-wideband and low-power consumption is proposed. The CG amplifier enables wide-band input matching with low transconductance and low frequency-independent noise figure (NF) when employed at the input stage compared with the common-source amplifier. The current-reuse technique is adopted in order to reduce the power dissipation while achieving reasonable power gain. In addition,

For hemoglobin changes, total tubeless and small-bore PCNLs may be superior to other methods. For hospital stay, total tubeless and tubeless PCNLs with stent may be superior to other procedures.

This meta-analysis suggests that perioperative parameters, including OR time and LOS, may be more favorable for EP-RARP than for TP-RARP. However, the oncologic outcome of margin positivity did not demonstrate a significant difference between the EP and TP approaches.

Our data indicate that a group 2 SSD of approximately 10 cm is a positive predictor for success following ESWL.

Microbiota are ecological communities of commensal, symbiotic, and pathogenic microorganisms. The microbiome could be involved in kidney stone formation through hyperoxaluria and calcium oxalate supersaturation, biofilm formation and aggregation, and urothelial injury. Bacteria bind to calcium oxalate crystals, which causes pyelonephritis and leads to changes in nephrons to form Randall’s plaque. The urinary tract microbiome, but not the gut microbiome, can be distinguished between cohorts with

Our meta-analysis showed that the higher CXCR4 protein expression in prostate cancer specimens is significantly associated with the presence of metastatic disease. This supports previous experimental data supporting the role played by the SDF-1/CXCR4 axis in metastasis.
