Comparison of Prognosis and Health-Related Quality of Life Between Robot-Assisted Radical Prostatectomy Versus High-Dose-Rate Brachytherapy Combined With External Beam Radiation Therapy and Hormone Therapy for High-Risk Prostate Cancer.

Background: We compare the oncological outcomes and health-related quality of life (HRQOL) in men with high-risk prostate cancer after robot-assisted radical prostatectomy (RARP) versus that after high-dose-rate brachytherapy + external beam radiotherapy + hormone therapy (hereafter: "HDR+").

Methods: We included 233 men who underwent RARP and 179 men who underwent HDR+ for high-risk prostate cancer at our hospital. We investigated the following oncologic outcomes: time to biochemical recurrence, time to development of castration-resistant prostate cancer (CRPC), cancer-specific survival, and overall survival.

Impact of postoperative sexual function on health-related quality of life after robot-assisted radical prostatectomy.

Background: We investigated potential disparities in health-related quality of life, particularly concerning urinary function, between patients with preserved and those with impaired sexual function after robot-assisted radical prostatectomy (RARP).

Materials And Methods: Between December 2012 and April 2020, 704 men underwent RARP in our hospital. This study included 155 patients with a preoperative 5-item International Index of Erectile Function (IIEF-5) of ≥12 points and an assessable IIEF-5 at 12 months postoperatively.

Verification of surgical factors affecting the efficiency of stone extraction with one-surgeon basketing technique using a f-URSL simulation model.

Purpose: Stone extraction is an important treatment option when performing flexible ureteroscopic lithotripsy (f-URSL) for upper urinary stones. We used a f-URSL simulator model to investigate surgical factors affecting the efficacy of stone extraction with the one-surgeon basketing technique.

Materials And Methods: This simulator-based study involved eight urologists and eight residents.

Area of hydronephrosis is a useful predictive factor of impacted ureteral stones.

Ureteroscopic lithotripsy for impacted stones is challenging, but it is important to predict impacted stones preoperatively. Hydronephrosis, which is evaluated by a grading system, is often apparent in impacted stones. However, the currently used grading system is a qualitative evaluation.

Poor performance status is a risk factor for higher detection of Gram positive coccus in stone-related pyelonephritis.

Introduction: We aimed to investigate the detection rate of causative organisms in stone-related pyelonephritis and to compare their distribution according to patient backgrounds.

Methods: We retrospectively identified patients with stone-related pyelonephritis. Clinical data were collected between November 2012 and August 2020 at Wakayama Medical University Hospital, including on patient backgrounds and causative organisms.

Efficacy of Bisphosphonate for Urolithiasis Complicated by Osteogenesis Imperfecta.

A 44-year-old man with osteogenesis imperfecta presented with left renal colic. Non-contrast computed tomography revealed a stone (10×9 mm) in the left upper ureter. Ureteroscopic lithotripsy was performed twice and stone-free status was achieved.

Thermography-Based Comparison of Irrigation Temperatures Between Moses Mode and Virtual Basket Mode: An Phantom Study.

This study aims to evaluate changes in irrigation fluid temperatures during laser activation by using thermography, with comparison between Moses mode (MM) and virtual basket mode (VBM). Experiments were performed using an unroofed pyelocaliceal model. The laser was fired for 60 seconds at 0.

The ratio of CT attenuation values of the ureter above/below ureteral stones is a useful preoperative factor for predicting impacted ureteral stones.

Impacted stones typically make it difficult to perform ureteroscopic lithotripsy (URSL), so it is useful to preoperatively predict such impaction. We focused on CT attenuation values of the ureter above and below the stone ('HU above' and 'HU below') and calculated their ratio (HAB ratio; HU above/HU below ratio). The aim was to investigate whether HAB ratio could predict impacted stones preoperatively.

Usefulness of Preoperative High Systemic Immune-Inflammation Index as a Prognostic Biomarker in Patients Who Undergo Radical Cystectomy for Bladder Cancer: Multicenter Analysis.

Evidence of the prognostic value of pretreatment systemic immune-inflammation index (SII) after radical cystectomy (RC) for bladder cancer is limited. This study aims to assess the association between preoperative SII and prognosis after RC for bladder cancer. In this multicenter retrospective study, we calculated preoperative SII as well as the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in 237 patients who underwent RC for bladder cancer between March 2009 and March 2018.

Undifferentiated pleomorphic sarcoma of the prostate in a young man.

Introduction: Prostate sarcoma is an extremely rare disease with a poor prognosis. Undifferentiated pleomorphic sarcoma has never been described in the prostate. A 27-year-old man complained of frequent urination and dysuria for several years.

Myosteatosis as a novel prognostic biomarker after radical cystectomy for bladder cancer.

This study aims to evaluate the influence of myosteatosis on survival of patients after radical cystectomy (RC) for bladder cancer. We retrospectively identified 230 patients who underwent RC for bladder cancer at our three institutions between 2009 and 2018. Digitized free-hand outlines of the left and right psoas muscles were made on axial non-contrast computed tomography images at level L3.

Three-dimensional mean stone density on non-contrast computed tomography can predict ureteroscopic lithotripsy outcome in ureteral stone cases.

The association between mean stone density (MSD) and ureteroscopic lithotripsy outcome remains controversial. MSD automatically measured by 3D images of stones (3D-MSD) was recently reported to be more useful than manual measuring methods for predicting outcomes of shock-wave lithotripsy. This study aims to investigate whether 3D-MSD can predict ureteroscopic lithotripsy outcome.

Noncontrast Computed Tomography Parameters for Predicting Shock Wave Lithotripsy Outcome in Upper Urinary Tract Stone Cases.

Kidney stones are a major public health concern with continuously increasing worldwide prevalence. Shock wave lithotripsy (SWL) is the first line treatment choice for upper urinary tract calculi with ureteroscopy and has advantages of safety and noninvasiveness, but the treatment success rate of SWL is lower than that of other therapies. It is therefore important to identify predictive factors for SWL outcome and select a suitable treatment choice for patients with upper urinary tract calculi.
