Pancreatitis as immune-related adverse event during pembrolizumab therapy for multiple lung metastases from renal pelvic cancer.

Introduction: Pembrolizumab administration has become the standard of care for patients with urothelial carcinoma, though a variety of adverse events have been reported. Presented here is a rare case of pancreatitis that occurred as an immune-related adverse event.

Case Presentation: An 81-year-old man undergoing treatment with pembrolizumab for multiple lung metastases from renal pelvic cancer was presented with a fever and diagnosed with pancreatitis based on elevated pancreatic enzyme levels and imaging findings.

[Advanced Bladder Cancer with Multiple Pulmonary Metastases Treated with Paclitaxel/Ifosfamide/Nedaplatin Therapy : Two Case Reports].

The standard treatment for advanced urothelial carcinoma includes platinum-based chemotherapy and programmed cell death protein 1 or programmed death ligand 1 inhibitors. However, urothelial carcinomas are often associated with both intrinsic and acquired resistance to these treatments. Paclitaxel, ifosfamide, and nedaplatin (TIN) chemotherapy has been proven to be effective as the second- or third-line treatment for platinum-resistant advanced urothelial cancer.

A case of Avelumab response to multiple bone and lymph node metastases of plasmacytoid variant bladder cancer.

A 74-year-old man was diagnosed with bladder cancer and referred to our department. For definitive diagnosis, transurethral resection of the bladder tumor(TURBT) was performed. The pathological result showed plasmacytoid variant of urothelial carcinoma.

[A Case of Multiple Penile Schwannoma].

A 48-year-old man presented with a painless nodule on the right ventral aspect of the penile shaft root. The patient visited the hospital and complained that the mass was growing. On physical examinations, a 5 cm mass without tenderness was palpated.

A case of renal schwannoma.

The patient was referred to our department from neurosurgery for close examination of a renal mass that had been present in the lower pole of the kidney for approximately 2 year. Retrograde Pyelography and Ureteroscopy showed no obvious neoplastic lesion in the renal pelvis. Therefore, Percutaneous renal tumor biopsy was performed.

[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.

[A Case of Isolated Peritoneal Metastasis from Prostate Cancer].

Peritoneal metastasis of prostate cancer is extremely rare, with only a few cases reported. A 78-yearold male patient was introduced to our hospital presenting with a prostate-specific antigen (PSA) level of 94.0 ng/ml at examination.

Primary small cell neuroendocrine carcinoma of adrenal gland.

Neuroendocrine tumors are an extremely rare form of retroperitoneum tumor. A 79-year-old man presented with abdominal pain. Computed tomography and magnetic resonance imaging revealed a 51 × 36 mm mass in the left adrenal gland.
