The optimal management of large upper ureteral stones (> 1.5 cm) with infection in elderly patients: a comparative analysis of three minimally invasive surgical approaches.

Purpose: The aim of this study was to investigate the efficacy and safety of three minimally invasive surgical approaches for treating large upper ureteral stones complicated by infection in elderly (> 60 years) patients.

Methods: Clinical data from 95 elderly patients with large upper ureteral stones and infection, treated at our hospital between January 2018 and April 2023, were retrospectively analyzed. The surgical approaches included FURL (flexible ureteroscopic lithotripsy) 33 cases, mPCNL (minimally percutaneous nephrolithotomy) 29 cases, and RLUL (retroperitoneal laparoscopic ureterolithotomy) 33 cases.

Comparing surgical site wound infection after laparoscopic and open radical cystectomies in patients with bladder cancer.

This study comprehensively compared the effects of laparoscopic and open radical cystectomies on postoperative wound infections and complications in patients with bladder cancer. We conducted a systematic search for relevant studies in PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases, from database inception to October 2023. Two researchers independently screened the literature, extracted data, and assessed the quality based on the inclusion and exclusion criteria.

Application value of extreme flexion and abduction hip combined with stirrup-shaped multifunctional leg frame in blocking obturator nerve reflex in transurethral resection of bladder tumor.

Objective: To explore the effectiveness and safety of the extreme flexion and abduction hip combined with a stirrup-shaped multifunctional leg frame position in preventing obturator nerve reflex during plasma resection of bladder tumors (TUR-BT).

Methods: A total of 112 patients with bladder tumors were included in the study. The control group was placed in a lithotomy position, while the experimental group was placed in an extreme flexion and abduction hip combined with a stirrup-shaped multifunctional leg frame position.

The relationship between inflammatory response markers and the prognosis of non-muscle invasive bladder cancer and the development of a nomogram model.

Purpose: Patients with non-muscle invasive bladder cancer (NMIBC) have a high possibility of recurrence after surgery. We aimed to assess the factors associated with tumor recurrence and to construct a nomogram model that can contribute to personalized treatment plans of each patient.

Methods: 496 patients with primary bladder cancer (BC) from 2 centers were retrospectively analyzed.

Application of Flexible Holmium Laser Sheath in Rigid Ureteroscopy for the Treatment of Impacted Upper Ureteral Stones.

Objective: By comparing with rigid ureteroscopy (r-URS), we explored the application value of flexible holmium laser sheath combined with r-URS in treating impacted upper ureteral stones. We also verified its effectiveness, safety and economy and investigated its application prospects at community or primary hospitals.

Methods: From December 2018 to November 2021, 158 patients with impacted upper ureteral stones were selected from Yongchuan Hospital of Chongqing Medical University.

The comparison between contrast-enhanced ultrasound and contrast-enhanced magnetic resonance imaging in diagnosing bladder urothelial carcinoma.

Purpose: The surgical treatment of bladder urothelial carcinoma depends on whether the tumor has invaded the bladder muscular layer. Normal ultrasound and contrast-enhanced magnetic resonance imaging (contrast-enhanced MRI) are widely used in patients bear bladder tumors; the latter is also widely used in estimating the muscularis invasion of bladder cancer (BC). However, contrast-enhanced ultrasound (CEUS) is rarely used in this aspect.

A Nomogram Model to Predict Recurrence of Non-Muscle Invasive Bladder Urothelial Carcinoma After Resection Based on Clinical Parameters and Immunohistochemical Markers.

Objective: This study aims to establish a nomogram model by combining traditional clinical parameters with immunohistochemical markers to predict the recurrence of non-muscle invasive bladder urothelial carcinoma (NMIBUC) after resection.

Methods: In total, 504 patients were included in this study. Of these patients, 353 underwent transurethral resection of bladder tumor (TURBT) in the Yongchuan Hospital of Chongqing Medical University and were identified as a training cohort.
