BACKGROUND The aim of this study is to compare the perioperative outcomes and learning curves between intracorporeal and extracorporeal urinary diversion at our medium-sized institution. METHODS Between January 2018 and September 2020, a single surgeon at our institution performed 46 consecutive robot-assisted radical cystectomies with ileal conduit. We compared the perioperative outcomes between patients who underwent intracorporeal versus extracorporeal urinary diversion. We also investigated ...

BACKGROUND Among various clinicopathologic factors used to identify low-risk upper tract urothelial carcinoma (UTUC), tumor grade and stage are of utmost importance. The clinical value added by inclusion of other risk factors remains unproven. OBJECTIVE To assess the performance of a tumor grade- and stage-based (GS) model to identify patients with UTUC for whom kidney-sparing surgery (KSS) could be attempted. DESIGN, SETTING, AND PARTICIPANTS In this international study, we reviewed the medical...

PURPOSE To evaluate the efficacy of holmium laser enucleation of the prostate (HoLEP) in patients with a small prostate volume (≤30 mL). MATERIALS AND METHODS We retrospectively evaluated 1,135 patients who underwent HoLEP at two institutions between July 2007 and March 2020. Patients who were not evaluated for the International Prostate Symptom Score (IPSS) before or after HoLEP were excluded. We divided patients into two groups according to estimated prostate volume (ePV): ≤30 (n=198) and >30 ...

ABSTRACT Background We investigated the association between ABO-incompatible (ABO-I) kidney transplantation and early graft function. Methods We retrospectively analyzed 95 patients who underwent living donor kidney transplantation between May 2009 and July 2019. It included 61 ABO-compatible (ABO-C) and 34 ABO-I transplantations. We extracted data on immunologic profile, sex, age, cold ischemic time, type of immunosuppression, and graft function. Two definitions were used for slow graft functio...

BACKGROUND Neutrophils play a major role in ischemia/reperfusion injury (IRI) in renal transplantation and acute kidney injury. However, it has been difficult to observe changes in neutrophil dynamics over time in living mice kidney. We investigate neutrophil dynamics in IRI in living mice using novel in vivo multiphoton microscope imaging techniques and characterize the renoprotective effects of a selective phosphodiesterase (PDE) 5 inhibitor, tadalafil. METHODS Wild-type (WT) and eNOS knockout...

Anemia and vitamin D deficiency are associated with allograft failure, and hence, are potential therapeutic targets among kidney transplant recipients (KTRs). We conducted a multicenter, two-by-two factorial, open-label, randomized clinical trial to examine the effects of anemia correction and vitamin D supplementation on 2-year change in eGFR among KTRs (CANDLE-KIT). We enrolled 153 patients with anemia and >1-year history of transplantation across 23 facilities in Japan, and randomly assigned ...

INTRODUCTION The aim of this study was to monitor the development of drug-resistant bacteria isolated from acute uncomplicated cystitis (AUC) and to evaluate methodology of the survey conducted by collecting only clinical data. METHODS We enrolled female patients at least 16 years of age diagnosed with AUC in 2018. Patient information including age, menopausal status, and results of bacteriological examination were collected and analyzed regardless of bacterial identification, antimicrobial susc...

Purpose With the advance of screening techniques, there is a growing number of low-risk or intermediate-risk prostate cancer (PCa) cases, remaining a serious threat to men's health. To obtain better efficacy, a growing interest has been attracted to develop such emerging treatments as immunotherapy and focal therapy. However, few studies offer guidance on whether and how to combine these modalities against PCa. This study was designed to develop dual-functional nanoparticles (NPs) which combined...

Objectives: The Gleason scoring system is an essential tool for determining the treatment strategy in prostate cancer (PCa). However, the Gleason grade group (GGG) often differs between needle-core biopsy (NCB) and radical prostatectomy (RP) specimens. We investigated the diagnostic value of a second opinion pathology review using NCB specimens in PCa. Materials and Methods: We retrospectively evaluated 882 patients who underwent robot-assisted RP from January 2012 to September 2019. Of these, p...
