Urinary bladder metastasis from breast cancer: A rare case report.

Breast cancer is a major contributor to cancer-related morbidity and mortality in women, which is primarily attributed to metastases. Common metastatic sites include the lungs, liver, and bone, whereas bladder metastasis is rare. We report a case of bladder metastasis from breast cancer in a 61-year-old woman, highlighting the challenges in diagnosis and treatment.

Real-world sequential treatment patterns and clinical outcomes among patients with advanced urothelial carcinoma in Japan.

Objectives: Immune checkpoint inhibitors and enfortumab vedotin have opened new avenues for sequential treatment strategies for locally advanced/metastatic urothelial carcinoma (la/mUC). In the pre-enfortumab vedotin era, many patients could not receive third-line treatment owing to rapid disease progression and poor general status. This study aimed to analyze real-world sequential treatment practices for la/mUC in Japan, with a focus on patients who do not receive third-line treatment.

Bilateral adrenal metastases from renal cell carcinoma after robot-assisted partial nephrectomy.

Renal cell carcinoma often metastasizes to the adrenals; however, bilateral adrenal metastases are rare.

A 78-year-old man was treated with Bortezomib, Lenalidomide, and Dexamethasone, for multiple myeloma. Two years after the start of treatment, the patient came to our department with a complaint of gross hematuria. Cystoscopy revealed a tumor on the left wall of the bladder.

Clinical practice pattern in patients with advanced urothelial cancer who had progressed on pembrolizumab in the pre-enfortumab vedotin era.

Objectives: Pembrolizumab, an anti-PD-1 monoclonal antibody, revolutionized the treatment for advanced urothelial carcinoma. However, the standard treatment for patients after disease progression with pembrolizumab had not been established until the recent approval of enfortumab vedotin. We analyzed the treatment of these patients in the real world, and the patient background and outcomes.

[A Case of Primary Renal Angiosarcoma with a Rapidly Worsening Course].

A 69-year-old man presented with left flank pain and underwent a computed tomographic scan, which revealed a large left renal mass of 16×9×5 cm. A left nephrectomy was performed. Pathological analysis revealed that the tumor was consistent with angiosarcoma of the left kidney with a negative surgical margin.

Robot-assisted partial nephrectomy via retroperitoneal approach in a patient with horseshoe kidney.

Introduction: Horseshoe kidney is a renal fusion anomaly often associated with ectopia, malformation, and vascular changes. Robot-assisted partial nephrectomy is selected for patients with T1a renal cell carcinoma; however, there are few reports of renal cell carcinoma in horseshoe kidney. We present a case of robot-assisted partial nephrectomy via a retroperitoneal approach in a patient with horseshoe kidney with a brief literature review.

[A Case of Ureteral Metastasis from Prostate Cancer].

Ureteral metastasis from prostate cancer is rare. The present case report describes an 83-year-old patient with distant metastasis of prostate cancer to the right ureter that caused hydronephrosis. Upon initial examination at our hospital, he presented with a high prostate-specific antigen (PSA) level of 10.

Rapid recurrence of squamous cell carcinoma at a lymphocele after nephroureterectomy: A rare case report.

Introduction: Lymphoceles are sometimes formed after pelvic lymph node dissection. However, recurrence at lymphoceles has not been reported previously. Here, we report a case of rapid prognosis of the recurrence at a lymphocele after nephroureterectomy.

[Clinical Course and Treatment of Acute Urinary Retention after Robot- Assisted Laparoscopic Radical Prostatectomy : A Single Institution Experience of 11 Cases].

Robot-assisted laparoscopic radical prostatectomy (RARP) is becoming the standard treatment procedure for localized prostate cancer. The main complications associated with RARP include urinary incontinence and sexual dysfunction. In addition, acute urinary retention (AUR) after urethral catheter removal is sometimes seen.

[Radical Nephroureterectomy in Octogenarians].

We compared the perioperative and oncological outcomes of radical nephroureterectomy for renal pelvic and ureteral cancer between octogenarians and younger patients. We examined 146 patients attending our hospital from January 2012 to December 2019. The octogenarian group included 48 patients and the control group (younger patients) 98 patients.

Black adrenal adenoma causing subclinical Cushing's syndrome complicated with pheochromocytoma.

Introduction: The development of adrenocortical adenoma and pheochromocytoma within the same adrenal gland is very rare. Furthermore, no reports have described coincident black adrenal adenoma and pheochromocytoma. We herein report a rare case of coincident black adrenal adenoma and pheochromocytoma in the same adrenal gland.

Port-site incisional hernia from an 8-mm robotic trocar following robot-assisted radical cystectomy: Report of a rare case.

Introduction: Port-site incisional hernia is a rare but well-known complication following a laparoscopic procedure and it may cause severe adverse outcomes, such as intestinal necrosis. Here, we report a rare case of hernia that occurred from an 8-mm trocar after robot-assisted radical cystectomy.

Case Presentation: An 80-year-old woman was diagnosed with cT2bN1M0 bladder cancer.

Prognosis of patients with muscle invasive bladder cancer who are intolerable to receive any anti-cancer treatment.

Background: The aim of this retrospective study was to evaluate the prognosis of patients who had been diagnosed with muscle invasive bladder cancer (MIBC) and did not receive anti-cancer treatment because of their physical characteristics.

Methods: Between January 2012 and October 2019, 96 patients were diagnosed with MIBC (cT2-4N0M0) in our institution. Of those, 64 patients had undergone radical cystectomy (RC), 6 had received palliative radiation therapy, and 26 had not received any anti-cancer treatment.

Two Applications for Laparoscopic Combined Ventral and Dorsal Side Approach in the Lateral Decubitus Position: (1) Right-Modified Retroperitoneal Lymph Node Dissection, (2) Nephrectomy for Horseshoe Kidney.

Background: Laparoscopic retroperitoneal lymph node dissection (RPLND) in metastatic testicular cancer is a technically challenging procedure. In right-modified RPLND, retrocaval lymph nodes are often not visible and cannot be adequately dissected using only the transperitoneal approach. In laparoscopic nephrectomy (LN) for horseshoe kidney, the kidney cannot be sufficiently moved due to its connection to the contralateral kidney, and the isthmus and lower poles have separate blood supplies arising from the aorta or iliac artery.

The third national Japanese antimicrobial susceptibility pattern surveillance program: Bacterial isolates from complicated urinary tract infection patients.

The antimicrobial susceptibility patterns of bacterial pathogens isolated from patients with complicated urinary tract infections were analyzed using national surveillance data. The data consisted of 881 bacterial strains from eight clinically relevant species. The data were collected for the third national surveillance project from January 2015 to March 2016 by the Japanese Society of Chemotherapy, the Japanese Association for Infectious Disease, and the Japanese Society of Clinical Microbiology.

Comparison of single- and multiple-dose cefazolin as prophylaxis for transurethral enucleation of prostate: A multicenter, prospective, randomized controlled trial by the Japanese Research Group for Urinary Tract Infection.

Objectives: To compare the optimal administration period of antimicrobial prophylaxis in patients undergoing transurethral enucleation of the prostate for benign prostatic hyperplasia.

Methods: We carried out a randomized controlled trial to compare the differences in incidence of perioperative genitourinary tract infection between single and multiple (3 days) administrations of cefazolin for transurethral enucleation of the prostate in benign prostatic hyperplasia patients without pyuria or bacteriuria between January 2015 and December 2018.

Results: This multicenter randomized controlled trial included 203 patients who underwent a transurethral enucleation of the prostate procedure.
