Understanding the ablation rate of Holmium:YAG and thulium fiber lasers. Perspectives from an in vitro study.

This study sought to analyze the ablation rates of Holmium:YAG (Ho:YAG) and thulium fiber laser (TFL) under different settings combinations. Lasering was carried out by a computed spiral pattern through a stepper motor bearing a laser fiber. BegoStones were placed inside a water container and lasered therein and the ablation rate was calculated.

Can we omit systematic biopsies in patients undergoing MRI fusion-targeted prostate biopsies?

Magnetic resonance imaging (MRI)-targeted prostate biopsy is the recommended investigation in men with suspicious lesion(s) on MRI. The role of concurrent systematic in addition to targeted biopsies is currently unclear. Using our prospectively maintained database, we identified men with at least one Prostate Imaging-Reporting and Data System (PI-RADS) ≥3 lesion who underwent targeted and/or systematic biopsies from May 2016 to May 2020.

Simultaneous Bilateral Endoscopic Surgery (SBES): Is It Ready for Prime Time?

To date, some data available in literature on simultaneous bilateral endoscopic surgery (SBES) have shown good outcomes in terms of both effectiveness and safety. The aim of this study was to report the outcomes pertaining to the effectiveness and safety of SBES performed in our series of patients with bilateral renal stones. A prospective analysis of consecutive patients who underwent SBES for bilateral renal stones at our institution between June 2017 and September 2021 was performed.

Endourologic Treatment of Late Migration of Embolization Causing Nephrolithiasis in Two Patients.

Selective renal artery angioembolization is the first treatment option in case of significant bleeding after percutaneous nephrolithotomy. Migration of embolization material into the collecting system is extremely rare. The treatment of this condition is not standardized, but manual extraction, ultrasound fragmentation, and holmium laser lithotripsy have been described.

Holmium laser for RIRS. Watts are we doing?

Objective: To review recent and relevant information regarding the use of high-power (HPL) and low-power (LPL) Holmium:YAG lasers (Ho:YAG) in retrograde intrarenal surgery (RIRS) for lithotripsy. METHODS: A PubMed/Embase search was conducted and recent and relevant papers on Ho:YAG for RIRS were reviewed.

Results: Settings for Ho:YAG are pulse energy (PE), pulse frequency (PF), and pulse width.

Thulium:YAG Holmium:YAG Laser Effect on Upper Urinary Tract Soft Tissue: Evidence from an Experimental Study.

There are limited data regarding the effect of thulium laser (Tm:YAG) and holmium laser (Ho:YAG) on upper urinary tract. The aim of this study was to compare soft tissue effects of these two lasers at various settings, with a focus on incision depth (ID) and coagulation area (CA). An experimental study was performed in a porcine model.

MRI Fusion-Targeted Transrectal Prostate Biopsy and the Role of Prostate-Specific Antigen Density and Prostate Health Index for the Detection of Clinically Significant Prostate Cancer in Southeast Asian Men.

Objective: To test the hypothesis that targeted biopsy has a higher detection rate for clinically significant prostate cancer (csPCa) than systematic biopsy. We defined csPCa as any Gleason sum ≥7 cancer. In patients with Prostate Imaging Reporting and Data System (PI-RADS) 3 lesions, to determine if factors, such as prostate-specific antigen density (PSAD) and prostate health index (PHI), can predict csPCa and help select patients for biopsy.

Xanthogranulomatous pyelonephritis presenting as Proteus preperitoneal abscess.

Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic pyelonephritis with progressive loss of renal function. Commonly, obstructing urinary calculi are seen. It is difficult to differentiate between XGPN and malignancy in many cases, and the diagnosis is usually only confirmed post-operatively upon histopathological examination of the specimen.

Is emergency right hemicolectomy still associated with significant morbidity and mortality rates? An institution's experience of 207 cases over 6 years.

Introduction: Emergency right hemicolectomy has been associated with dismal outcome. But, data in Asians is lacking as pathologies that require emergency right hemicolectomy may differ from that in the Western population. The aims of our study were to review our institution's experience with emergency right hemicolectomies and to identify factors that could predict the per-operative outcome.
