A case of rapidly progressive prostate cancer with bone and lymph node metastasis after contact laser vaporization for benign prostatic hyperplasia.

Introduction: Prostate cancer is incidentally diagnosed in 6%-11% of benign prostatic hyperplasia surgeries.

Case Presentation: A 79-year-old man was diagnosed with benign prostatic hyperplasia. The prostate volume was 54.

Sterile versus non-sterile gloves during cystoscopy: A randomized prospective single-blind study.

Objective: The objective of this study is to evaluate the need for sterile gloves during cystoscopy by comparing the incidence of UTI symptoms between patients in whom the procedure is performed with non-sterile gloves with those performed with non-sterile gloves.

Patients And Methods: This study had a randomized, prospective, single-blind design and included patients aged >20 years who underwent cystoscopy in either of two outpatient clinics between September 2015 and November 2021. The patients were allocated to a sterile group or a non-sterile group.

[The Effect of Naldemedine Tosylate on the Postoperative Course of Robot-Assisted Radical Cystectomy].

Radical cystectomy is an invasive procedure frequently followed by postoperative complications. Although the protocol of enhanced recovery after surgery (ERAS) is used in the postoperative course, several components of the ERAS protocol may increase the workload of medical workers. In this study, we added naldemedine tosylate only to routine postoperative management instead of using the ERAS protocol and evaluated the effect on the postoperative course of robot-assisted radical cystectomy (RARC).

[Challenging Case of Primary Renal Castleman's Disease Accompanied with Bacterial Pyelonephritis].

Castleman's disease is a rare lymphoproliferative disease, mostly found in the mediastinum. The number of Castleman's disease cases involving the kidneys is still limited. We report a case of primary renal Castleman's disease sporadically detected during a regular health check-up as pyelonephritis with ureteral stones.

[Efficacy of Combination Chemotherapy of Gemcitabine and Nedaplatin for Squamous Cell Carcinoma of the Urinary Tract : Experience of Four Cases].

We report the use of combination chemotherapy of gemcitabine (800 mg/m² on day1 and 8) and nedaplatin (60 mg/m² on day 1), including neoadjuvant therapy in four cases of squamous cell carcinoma of the urinary tract. In each case, the dose was reduced after assessing the performance status and renal function of the patient. Among the four cases, the best overall outcome was complete response in one case, partial response in two cases, and stable disease in one case.

Triple combination therapy for clinically nonmetastatic super-high-risk prostate cancer.

Introduction: Patients with nonmetastatic but exceptionally high-risk prostate cancer are liable to have biochemical failure and may even die. Triple combination therapy, which consists of surgery, radiotherapy, and androgen-deprivation therapy, as first-line treatment, may control the disease for a long period.

Case Presentation: We treated a patient with super-high-risk, nonmetastatic prostate cancer, with triple combination therapy.
