Prostatic urethral lift (PUL) for benign prostatic hyperplasia has recently been initiated in Asia; therefore, few studies with real-world data have been reported. This study evaluated the efficacy and safety of PUL using Japanese real-world multicenter data.

We evaluated the incidence of and risk factors for postoperative infections after robotic-assisted radical prostatectomy (RARP) according to the type and duration of prophylactic antibiotic administration.

While the occurrence of immune-related adverse events has been recognized as a prognostic marker in patients receiving immune checkpoint inhibitors, the prognostic significance of treatment-related adverse events (trAEs) in patients undergoing antibody-drug conjugates such as enfortumab vedotin (EV) is controversial.

This study aimed to investigate the long-term effectiveness and safety of transvaginal mesh surgery for pelvic organ prolapse at a high-volume center in Japan.

Kidney transplantation is the treatment of choice even for the elderly, as it improves quality of life and life expectancy, lowering the financial burden to the health care system compared to dialysis therapy. In Japan, kidney transplant recipients have become older due to the shift in demographics. Compared to community-dwelling elderly adults, elderly kidney transplant recipients undergoing immunosuppressive therapy have a higher risk of age-related outcomes including hospital readmissions, infections, dementia, malignancies, and fractures. In frailty, patients become vulnerable to adverse events after stressors due to a lack of physiologic reserve. Although it is often associated with aging, frailty can also occur in younger individuals with certain chronic illnesses or conditions including chronic kidney disease. Limited compensatory mechanisms result in functional impairment and adverse health outcomes, such as disability, falls, decreased mobility, hospitalization, and death. Although kidney transplant recipients can restore their kidney function after transplantation, most of them still have chronic kidney disease, as well as a gradual decline in graft function as a result of chronic allograft nephropathy. Wait-listed candidates for kidney transplantation with frailty are more likely to experience wait-list removal or death. Frailty at the time of transplantation is associated with complications after kidney transplantation such as delayed graft function, longer hospital stays, rehospitalizations, immunosuppression intolerance, surgical complications, and death. Nevertheless, kidney transplantation can be a viable intervention for frailty in dialysis patients.

The advancement of laparoscopic surgery has allowed surgeons to see finer anatomical structures during surgery. As a result, several issues have arisen regarding Gerota fascia that cannot be explained by previous interpretations, such as its various forms observed during surgery. To address these issues, we histologically examined the structure of Gerota fascia.

α-1 blockers and dutasteride are widely used as agents to treat benign prostatic hyperplasia (BPH); the impact of these drugs on prostatic inflammation is still unclear. Herein, we investigated the impact of α-1 blockers and dutasteride treatment of BPH in terms of the degree of prostatic inflammation.

Seated voiding may be an attempt to obviate voiding dysfunction, improve physical stability during voiding, and prevent messy bathroom contamination. Therefore, we hypothesized that seated voiders had a higher prevalence of lower urinary tract symptoms (LUTS), deteriorating health conditions, and a higher marriage rate than standing voiders.

Surgical treatment for renal cell carcinoma (RCC) has drastically evolved for the past 30 years. However, survival outcomes of RCC according to times have not been fully elucidated, especially in the real-world setting. This study aimed to assess the survival improvement over time in RCC treated with nephrectomy by analyzing a longitudinal cohort using propensity score matching (PSM).

To evaluate comorbidities in Japanese testicular cancer (TC) survivors in a multi-institutional, cross-sectional study.

In the over 80 years since androgens were found to play a pivotal role in prostate cancer (PCa) progression, androgen deprivation therapy (ADT) has been a cornerstone in treating advanced PCa. Castration-resistant PCa persists, however, with some of these tumors evolving to androgen receptor (AR)-independent forms like neuroendocrine PCa. The development of novel diagnostic and therapeutic approaches to PCa is therefore crucial. This review provides an overview of recent basic research in PCa, focusing on two main areas: PCa cells and their tumor microenvironments. The first section describes current knowledge on the intricate mechanisms of AR signaling pathways, emphasizing the roles of coactivators and chromatin state alterations in gene regulation. Genomic analyses have revealed recurrent mutations and copy number alterations critical for precision medicine. Liquid biopsy has become a promising tool for real-time tumor monitoring, identifying genetic alterations in circulating-tumor DNA or extracellular vesicles. The second section describes the tumor microenvironment of PCa, highlighting its immunosuppressive landscape and the potential of combining ADT with immunotherapy. Advanced techniques, including single-cell RNA sequencing and spatial transcriptomics offer insights into cellular heterogeneity and interactions within the tumor microenvironment, paving the way for novel therapeutic strategies. Integration of these diverse research areas will provide a comprehensive understanding of the current state and future directions of PCa research, underscoring the importance of personalized medicine and the dynamic nature of cancer treatment strategies.
