Objective: We aimed to assess the impact of urinary diversion on survival in patients with advanced cervical cancer (CC) and hydronephrosis. Additionally, we examined the influence of other patient factors and urinary diversion type on survival.
Methods: A retrospective study analyzed survival in cervical cancer (CC) patients with hydronephrosis treated at two Mexican hospitals from 2011 to 2023. Patient data, including demographics, clinical, and pathological characteristics, were collected. Urinary diversion details and complications were recorded. Survival analysis was performed using Kaplan-Meier method and Cox regression model to identify predictors of survival.
Results: A total of 228 cervical cancer patients presenting with hydronephrosis were analyzed. Median follow-up was 9 months. The majority of patients were in stage IVA (44.3 %), with 66.7 % exhibiting bilateral renal involvement. Urinary diversion was performed in 192 patients (84.2 %). Median overall survival (OS) was 15.5 months. Multivariate analysis identified stage, disease course, oncologic treatment, laterality, performance status, and urinary diversion as independent prognostic factors for survival. In patients undergoing urinary diversion, bilateral renal involvement (HR 2.0) and deteriorated performance status (HR 3.6) were risk factors for mortality. Neither the laterality (unilateral or bilateral) nor the type of diversion significantly affected overall survival.
Conclusions: Survival in CC patients with hydronephrosis is influenced by factors such as: bilateral involvement, performance status, clinical stage, course and treatment of the underlying malignancy and urinary diversion. Urinary diversion improves survival, regardless of the specific diversion type or whether the diversion is unilateral or bilateral.

Urinary diversions are performed for a wide variety of indications, including bladder removal for cancer treatment, post-cancer treatment complications, trauma, or bladder pain. The robotic approach has been increasingly used in performing urinary diversions since the introduction of the surgical robot. A PubMed keyword search was performed on September 14, 2023 with the terms: robotic and urinary diversion.

Objective: To review and compare robot-assisted ipsilateral ureteroureterostomy (RALUU) and laparoscopic ipsilateral uretero-ureterostomy (LUU) in terms of efficacy and outcomes.
Methods: Clinical data of 65 children with complete renal ureteral duplication deformity admitted to the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022 were collected. Among these, 42 patients underwent laparoscopic ureteroureterostomy (LUU), designated as the LUU group, while 23 patients received robot-assisted laparoscopic ureteroureterostomy (RALUU), designated as the RALUU group.

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.

Type 2 diabetes mellitus is a well-known metabolic disease with increasing prevalence. Diabetic-related complications lead to different types of organ damage, some of which some of which are less well-known. In the lower urinary tract, a complex interplay of neuronal, myogenic, and urothelial dysfunction leads to functional disorders of the lower urinary tract, with disorders of bladder storage and bladder emptying being in the forefront.

Objective: To assess 30- and 90-day postoperative complication rates in patients who underwent robot-assisted radical cystectomy (RARC) after receiving novel immunotherapy-based neoadjuvant treatment.
Methods: A bi-centre analysis was conducted in patients who underwent RARC with intracorporeal urinary diversion and who received an immunotherapy-based neoadjuvant regimen between 2017 and 2023. Complications were classified using the Clavien-Dindo system.
