The follow-up of urothelial tumours is designed to allow early detection of recurrence or progression, for which treatment is possible. Recent interesting points are: the more frequent and simpler use of the new classification into low grade and high grade, essentially applied to the management and surveillance of tumours involving the mucosa or lamina propria; and the limited place of urinary markers.

Objective: To evaluate the correlation between ATP-binding cassette (ABC) transporter expression and therapeutic efficacy of enfortumab vedotin (EV), an antibody-drug conjugate targeting Nectin-4, in urothelial cancer, as only a few studies have been conducted on this topic.
Patients And Methods: This retrospective study included 20 patients with metastatic urothelial carcinoma (mUC), including bladder and upper urinary tract cancers, who were treated with EV at Dokkyo Medical University Hospital between 2022 and 2024. Immunohistochemical staining was performed on formalin-fixed, paraffin-embedded tissue samples.

Objective: Aim: To evaluate the expression levels of SOX-10 in tissues of bladder tumor and to prove the correlation between SOX-10 expression and clinicopathological characteristics of bladder tumors, including patient age, sex, tumor grade, and muscle invasion.
Patients And Methods: Materials and Methods: Forty formalin fixed paraffin embedded FFPE tissue blocks gathered by transurethral resection of bladder tumor are collected from teaching hospitals at Al-Najaf governorate. Those blocks were stained by hematoxylin and eosin.

Objective: Aim: To analyze expression levels of GATA-3 in bladder tumor tissues and to prove a relation between expression of GATA-3 and clinicopathological characteristics of bladder tumors, including patient age, sex, tumor grade, and muscle invasion.
Patients And Methods: Materials and Methods: Forty formalin fixed paraffin embedded (FFPE) tissue blocks obtained from bladder tumor by transurethral resection are collected from teaching hospitals at Al-Najaf governorate. Those blocks are stained by using hematoxylin and eosin stain.

Drug-induced hyponatremia is an adverse reaction with accelerated electrolyte disturbance. This study reported a rare case of delayed hyponatremia in a 68year-old female with recurrent upper tract urothelial carcinoma after Gemcitabine plus Cisplatin (GC) and Tislelizumab treatment. She had left ureter surgery, recurrence a year later with mildly abnormal kidney function (glomerular filtration rate (GFR) was 54.
