A 53-year-old female patient was diagnosed with a left renal mass incidentally detected on an abdominal computed tomography (CT) scan. Further examination revealed a slightly contrast-enhancing mass 2.0 cm in diameter, in the left kidney on a contrast-enhanced CT scan.

We report a case of primary renal peripheral T-cell lymphoma, not otherwise specified, treated with partial nephrectomy.
Case Presentation: A 63-year-old man was hospitalized with coronavirus infectious disease, emerged in 2019 in the emergency department.
Introduction: Malignancy during pregnancy requires consideration of both the mother and fetus. We report a patient with renal cell carcinoma during pregnancy who was treated with robot-assisted partial nephrectomy.
Case Presentation: The patient was incidentally found to have a renal mass on abdominal ultrasonography.
Introduction: Transient decrease in serum prostate-specific antigen level can occur after abiraterone acetate withdrawal in male patient with metastatic castration-resistant prostate cancer. Here, we report a case of abiraterone acetate withdrawal syndrome with transient prostate-specific antigen decrease after progression to castration-resistant disease while using upfront abiraterone therapy for high-risk prostate cancer.
Case Presentation: A 73-year-old man with hormone-sensitive high-risk prostate cancer with multiple bone metastases (prostate-specific antigen level, 294.
Recently, the number of patients with significant arteriosclerosis has been increasing owing to the aging of kidney transplant patients, an increase in the number of patients with kidney failure with diabetes as the primary disease, and an increase in the number of patients undergoing long-term dialysis. Severe atherosclerosis in kidney transplant recipients makes it difficult to determine the site of vascular anastomosis and increases the technical difficulty of the surgical procedure. This study presents a case of upside-down kidney transplantation in a recipient with severe arteriosclerosis.

We report a case of congenital vertebral tip dysplasia with type II collagen dysplasia in a patient who underwent robot-assisted radical prostatectomy. Congenital vertebral tip dysplasia is characterized by short stature, and in this case, the height was 130 cm, which was equivalent to that of an 8-year-old child.

- Immuno-oncology drugs like pembrolizumab have improved outcomes for patients with urothelial carcinoma but can cause varied and challenging side effects.
- A case study of an 84-year-old man with metastatic urothelial carcinoma treated with pembrolizumab revealed inflammation and edema in his joints, leading to a diagnosis of a specific immune-related condition.
- The treatment involved stopping pembrolizumab and using corticosteroids, followed by reintroduction of the immunotherapy after the patient's condition improved, highlighting the need for early diagnosis and management of side effects.
Article Synopsis
- - Ectopic ureteroceles are more common in children and typically found during prenatal ultrasounds or due to urinary infections, while they are rare in adults, with only 18 documented cases in Japan.
- - A 30-year-old male experienced urination difficulties including a weak stream and blood in urine, leading to the discovery of a 35 mm right ureterocele with a 7 mm stone via CT scan.
- - The patient underwent successful surgery involving transurethral resection of the ureterocele and stone removal, resulting in improved urination and no complications noted in follow-up visits.
A 72-year-old male underwent an abdominal CT scan, which revealed a 17-mm nodular incidentaloma in fat tissue in the left perirenal space. Retroperitoneoscopic surgery was performed to remove the tumor and histopathological results revealed a PSA-positive adenocarcinoma, which was diagnosed as a metastatic lesion associated with prostate cancer. PSA was high at 30.

A 57-year-old man with metastatic prostate cancer was referred to the emergency department for acute urinary retention. Cystoscopy and magnetic resonance imaging revealed a pedunculated mass measuring approximately 2 cm in size in the bladder neck that appeared to cause urinary obstruction in a ball valve-like manner.
