Objective: Sparse data exist on the impact of upper urinary tract (UUT) decompression on the risk of UUT recurrence in patients with bladder cancer (BCa). This study aims to evaluate whether Double J stenting (DJS) can increase the risk of UUT recurrence compared to percutaneous nephrostomy (PCN) placement.
Materials And Methods: We retrospectively analyzed data from 1550 patients with cTa-T3NanyM0 BCa who underwent radical cystectomy (RC) between at 12 tertiary care centers (1990-2020).

Article Synopsis
- Patients with multiple colorectal cancers (CRC) show distinct clinical characteristics, including a higher prevalence of strong family history and right-sided colon cancer compared to those with solitary CRC.
- A study analyzed 1,272 patients, revealing that 7.8% had multiple CRCs, with varying outcomes for synchronous and metachronous cases, particularly in terms of operation time and blood loss.
- Overall, minimally invasive surgery (MIS) is feasible for treating multiple CRCs, and recent advancements like indocyanine green fluorescence imaging have improved postoperative outcomes, including reducing anastomotic leakage rates.
The impact of double-J ureteral stenting before radical cystectomy on the development of upper tract urothelial carcinoma.

Background: It is controversial whether the use of a double-J stent (DJ) in patients with bladder cancer before radical cystectomy (RC) increases the risk of tumour seeding in the upper tract and thus the risk of metachronous upper tract urothelial carcinoma (UTUC). The aim of our study is to investigate the risk of upper tract recurrence after RC in patients previously managed with a DJ stent.
Methods: A total of 699 patients who had undergone RC between January 2003 and March 2022 with complete perioperative data and pathological outcome were included in our study.
Clinicopathological analysis of patients with dual malignancies: A retrospective study.

Background: This study aims to report the increasing incidence of second primary malignancies to better understand the association of multiple primary cancers and the duration of their occurrence. Keeping in view the current trends in dual malignancies and to further emphasize the importance of screening and follow-up diagnosis, we reviewed the records of patients who were diagnosed with dual malignancies.
Material And Methods: This is a retrospective observational study.

Multiple primary cancers are usually defined as primary malignant tumors of different histological origins in one person. Synchronous cancers are defined as two or more primary cancers diagnosed in the same patient at the same time or within six months after identifying the first tumor, and those cancers that develop at more than a six-month interval are termed as metachronous multiple primary cancers. Our study comprised of a patient with synchronous laryngeal cancer with double localizations.
