Metformin intake and risk of metabolic acidosis after radical cystectomy with urinary diversion: A comparative study using data from the TriNetX research network.

Purpose: To investigate the association of diabetes mellitus and metformin use with metabolic acidosis risk after radical cystectomy (RC) and urinary diversion for bladder cancer.

Materials And Methods: This retrospective cohort study used TriNetX Research Network data. Patients undergoing RC with continent diversion or ileal conduit for bladder cancer were identified using International Classification of Diseases, 10th Revision (ICD-10) and ICD-10 Procedure Coding System (ICD-10-PCS) codes.

En bloc resection of large bladder tumor: is it feasible and reasonable?

Purpose Of Review: Transurethral resection of bladder tumor (TURBT) remains the basis of bladder tumor diagnosis and an effective means of treating nonmuscle invasive bladder cancer (NMIBC). There are several limitations to this procedure: TURBT may cause free floating of malignant cells in the bladder and as a result re-implantation and early recurrence. Also, it does not allow the pathologist to define the correct spatial orientation of the specimen.

Differences in lasers and laser technologies: what does a clinician need to know?

Purpose Of Review: This review focuses on recent advancements in laser technologies used in urology, particularly in enucleation, vaporization, lithotripsy, and focal laser ablation (FLA). The growing use of the thulium fiber laser (TFL) and the development of pulsed thulium lasers (p-Tm:YAG) highlight the relevance of this review, as these innovations aim to improve precision and outcomes in urological procedures.

Recent Findings: Recent studies have shown the advantages of TFL in achieving precise tissue ablation, reduced retropulsion offered by the Moses technology in holmium lasers, and the potential of pulsed thulium lasers for more precise control of the effects on tissues.

Current Status of Neoadjuvant Treatment Before Surgery in High-Risk Localized Prostate Cancer.

Localized high-risk (HR) prostate cancer (PCa) is a heterogeneous disease whose likelihood of a biochemical recurrence, metastatic progression and cancer-related mortality after initial treatment is higher when compared with patients with low (LR) or intermediate-risk (IR) disease. In the past, neoadjuvant therapy has shown an improvement in postoperative oncological variables but failed to demonstrate any survival advantages. With the promising results from novel treatments in metastatic and non-metastatic castration resistant PCa settings, new evidence has appeared in the literature in the neoadjuvant setting.

Safety and efficacy of laser lithotripsy for treatment of bladder calculi: evidence from a systematic literature review.

Purpose Of Review: Bladder stones account for 5% of all urinary tract calculi. Contributing factors include bladder outflow obstruction, infections, foreign bodies, or neurogenic voiding dysfunction. This necessitates an effective treatment modality, and with advances in medical technology, minimally invasive techniques using lasers are being widely adopted.
