[Comparison of Mosesᵀᴹ Mode and Conventional Laser in Transurethral Lithotripsy for Kidney Stones].

Transurethral lithotripsy (TUL) using holmium YAG laser has become the standard treatment for kidney stones. Mosesᵀᴹ technology, which delivers the laser with less energy loss, has been introduced and is reported to have advantages over regular laser in terms of shorter operation time and lithotripsy efficiency, but there are few reports from general hospitals. We retrospectively compared the perioperative and postoperative outcome, and complications of 28 cases of TUL using Mosesᵀᴹ mode performed from August 2021 to January 2023 at our hospital, and 25 cases of TUL using regular laser from August 2020 to July 2021.

[A Case of Malacoplakia of the Prostate which was Difficult to Distinguish from Prostate Cancer].

A 70-year-old-man was referred with urination pain and pyuria. Prostate specific antigen was 10.6 ng/ml, and urine culture was Escherichia coli.

Paraurachal paraganglioma.

Introduction: Paragangliomas (PGLs) are frequently reported around the abdominal aorta; however, are extremely rare near the urachus.

Case Presentation: A 78-year-old woman was referred to the urology department of our hospital for further examination and treatment of a 1.2-cm tumor in the lower abdominal wall, a tumor excision was then performed.

[Testicular Preservation in a Patient with a Testicular Epidermoid Cyst Achieved by Preoperative Diagnosis : A Case Report].

Testicular epidermoid cysts are relatively rare, accounting for about 1% of all testicular tumors, and are often treated by high orchiectomy. We describe here the case of a testicular epidermoid cyst treated by testicle-sparing surgery due to a preoperative diagnosis. A 23-year-old man complained of a painless mass in the right scrotum.

[Deep and Durable Response After Discontinuation of Nivolumab/Ipilimumab Combination Therapy for Metastatic Renal Cell Carcinoma : A Case Report].

A 47-year-old man was referred to our hospital for epigastric pain and cough, and was given a diagnosis of left clear cell renal carcnoma with multiple pulmonary metastases based on the results of renal tumor biopsy (cT3aN0M1). He received nivolumab/ipilimumab combination therapy, but developed diarrhea (grade 3) on day71, and treatment was discontinued. However, a deep and durable response after discontinuation of treatment was shown, and we were able to perform nephrectomy on day336.

[A Case of Small Cell Carcinoma of the Bladder].

A 74-year-old man presented with further treatment for muscle invasive small cell carcinoma of the bladder. After three courses of neoadjuvant chemotherapy with cisplatine + etoposide (EP), total cystectomy was performed. The pathological findings revealed small cell carcinoma of the bladder (ypT2N0M0).

Combination treatment using percutaneous transluminal angioplasty and low-density lipoprotein apheresis in a patient with peripheral arterial disease and a history of chronic hemodialysis.

Peripheral arterial disease (PAD) is very common in dialysis patients, who tend to have diffuse calcification and severe peripheral arterial stenosis that make it difficult to treat limbs using only surgical or endovascular interventions. Better ways to treat this condition are therefore required and also follow-up studies to evaluate the effects of these treatments on the microcirculation. A 59-year-old man who had a cadaveric kidney transplant five years previously after 25 years of regular hemodialysis complained of pain at rest in his right lower limb and subsequently developed an intractable decubitus ulcer on his right fifth toe (Fontaine IV).
