Article Abstract

Introduction: Metastatic ureteral tumors are difficult to diagnose pathologically. Treatment is only available for the primary disease, and prognosis is generally poor.

Case Presentation: A 63-year-old patient with a history of gastric cancer presented with asymptomatic right-sided hydronephrosis. Ureteroscopic examination revealed tissue in the ureter consistent with gastric cancer. The lesion was localized, and the patient was treated with chemotherapy and radiotherapy as part of a multidisciplinary treatment. The prognosis was better than in other reports. To the best of our knowledge, this is the first case of a patient with metastatic gastric cancer who received multidisciplinary treatment including radiotherapy and had a good prognosis.

Conclusion: In cases where a localized metastatic ureteral tumor cannot be ruled out, ureteroscopy is an effective therapeutic strategy.

Background: Ureteral stents, such as double-J stents, have become indispensable in urologic procedures but are associated with complications like hematuria and pain. While the advancement of artificial intelligence (AI) technology has led to its increasing application in the health sector, AI has not been used to provide information on potential complications and to facilitate subsequent measures in the event of such complications.

Objective: This study aimed to assess the effectiveness of an AI-based prediction tool in providing patients with information about potential complications from ureteroscopy and ureteric stent placement and indicating the need for early additional therapy.

Purpose: To investigate the effect of the degree of hydronephrosis on extracorporeal shockwave lithotripsy (SWL) success in patients who underwent SWL due to upper ureteral stones.

Methods: Medical records of 878 patients who underwent SWL were retrospectively reviewed. Patients with isolated unilateral 6-10 mm radiopaque upper ureteral stones above the upper border of the sacroiliac joint were included in the study.

Objective: To test whether race/ethnicity affects stage or grade distribution at upper tract urothelial carcinoma (UTUC) diagnosis.

Methods: Within the Surveillance, Epidemiology, and End Results (SEER) database 2004-2020, UTUC patients were identified. Multivariable logistic regression models tested for the association between race/ethnicity and stage as well as grade at diagnosis according to renal pelvis vs.

Objective: This study aims to evaluate the impact of preoperative stenting on surgical outcomes and complications in patients with bilateral ureteric stones, specifically assessing its role in reducing the need for subsequent interventions.

Methods: A retrospective analysis was conducted at a tertiary center over eight years, involving 82 patients with bilateral ureteric stones. Patients were divided into two groups: Group 1 (no preoperative stenting) and Group 2 (preoperative stenting).

Purpose: To evaluate and compare the efficacy of a newly designed in-house assistive internal fluid circulatory device in ureteroscopic lithotripsy for ureteral stones.

Methods: In this study, 97 patients were assigned to the trial group and underwent ureteroscopic lithotripsy with an in-house newly designed assistive internal fluid circulatory device; 96 patients were assigned to the control group and underwent traditional ureteroscopic lithotripsy without the assistive device. The primary outcome was the final stone-free rate (SFR) at 1-month post-surgery.
