Switch-maintenance avelumab immunotherapy following first-line chemotherapy for patients with advanced, unresectable or metastatic urothelial carcinoma: the first Japanese real-world evidence from a multicenter study.

Objective: To develop the first Japanese real-world evidence of switch-maintenance avelumab in advanced, unresectable or metastatic urothelial carcinoma (aUC).

Methods: A multicenter-derived database registered 505 patients diagnosed with aUC between 2008 and 2021. Of these, 204 patients (40%) were selected and stratified according to the type of therapy used: maintenance avelumab group (27 [5.

[Management of Internal Ureteral Stent (Double J-Stent) Occlusion].

Occlusion of internal ureteral stents commonly called double-J (DJ) stent leads to renal dysfunction, urinary tract infection, and difficulty in replacing the stent. We investigated the cause of stent occlusion and whether DJ stent occlusion persisted with change in the type of stent. The internal ureteral stent, Bird® Inlay™ Optima or Boston Scientific® Tria™, was inserted in 43 ureters of 33 patients who underwent replacement more than three times between September 2017 and June 2020.

Response to Pembrolizumab After Dose-Reduced Cisplatin Plus Gemcitabine Chemotherapy Is Inferior to That After Carboplatin Plus Gemcitabine Chemotherapy in Cisplatin-Unfit Patients With Advanced Urothelial Carcinoma.

Introduction: Response to pembrolizumab after first-line chemotherapy is vital to prolonged survival in advanced, unresectable, and/or metastatic urothelial carcinoma (aUC). However, there are sparse clinical data on host-tumor immune modification by first-line platinum-based chemotherapy. This study investigated the association between response to first-line gemcitabine plus cisplatin (GC) or carboplatin (GCarbo) chemotherapy and response to subsequent pembrolizumab treatment.

[Retrospective Analysis of Severe Renal Infections Requiring Nephrectomy to Control Infection].

Patients who contract severe renal infections often suffer from urosepsis. Therefore, early diagnosis and treatment are required. Sometimes, the treatment with antibiotics is not enough for control of the infections.

Initial experience of complete laparoscopic radical nephroureterectomy combined with transvesical laparoscopic excision of distal ureter in patients with upper urinary tract cancer.

Background: Selecting the treatment procedure for cancer patients is a challenging task. We report our initial experience of complete laparoscopic radical nephroureterectomy (RNU) for patients with upper urinary tract urothelial cancer (UTUC).

Methods: A total of four patients with UTUC underwent complete laparoscopic RNU combined with transvesical laparoscopic excision of the distal ureter using three 5-mm ports.

[Misdirection of a Catheter for Clean Intermittent Catheterization into the Upper Ureter in a Female Patient with Neurogenic Bladder Due to Myelomeningocele : A Case Report].

We report a case of misdirection of a catheter for clean intermittent catheterization (CIC) into the ureter. A four-year-old girl with neurogenic bladder due to myelomeningocele had been managed with CIC by her parents for several years. From about a month before her visit, macroscopic hematuria appeared intermittently followed by abdominal pain and fever-up for a short time which ceased spontaneously.
