Patients with kidney or ureteral stones confirmed at non-contrast computed tomography and treated by flexible ureteroscopy with laser lithotripsy were enrolled...

OBJECTIVE: To emphasize preventive measures and outline management strategies for inadvertent ureteral cannulation. METHODS: We present a case report and conduct a literature review of 39 case reports on ureteral cannulation, examining a total of 48 patients. RESULTS: About 67% of the cases were female, and long-term catheterization was observed in 67% of the cases. Neurological conditions such as spinal cord injury (SCI), stroke, dementia, multiple sclerosis, and myasthenia gravis were the primary factors (48%) in ureteral cannulation...

BACKGROUND: Success rates in endourological procedures, notably percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS), have demonstrated suboptimal outcomes, leading to more reinterventions and radiation exposure. Recently, the use of intraoperative computed tomography (ICT) scans has been hypothesized as a promising solution for improving outcomes in endourology procedures. With this considered, we conducted a comprehensive systematic review and meta-analysis encompassing all available studies that evaluate the impact of the use of intraoperative CT scans on surgical outcomes compared to conventional fluoroscopic-guided procedures...

PURPOSE: We searched for perioperative renal function deterioration risk factors in patients that underwent bilateral flexible ureteroscopy (fURS) for kidney stones. METHODS: From August 2016 to February 2020, symptomatic patients > 18 years old with bilateral kidney stones up to 20 mm in each side were prospectively studied. Serum creatinine samples were collected on admission to surgery, immediate postoperative (IPO), on POD 3, 10, and 30...

OBJECTIVE: To determine the complications of ureteric stone treatment with semi-rigid uretero-renoscopy in accordance with the modified Clavien classification system.

All patients were subjected to ureterorenoscopy using a semi-rigid ureteroscope under general anaesthesia...

INTRODUCTION: Health-related quality of life (HRQoL) is often reduced in patients with urolithiasis. The objective of this study was to perform a systematic review to describe impact on HRQoL based on different modalities of treatment for small urolithiases with a diameter smaller or equal to 10 mm. METHODS: Electronic databases were searched with no language or date restrictions to identify studies which were included if they reported: adult patients (≥18 years old), renal or ureteral stone(s) confirmed on imagery, validated reporting of HRQoL, and stone diameter equal or smaller than 10 mm undergoing active surveillance, medical expulsive therapy (MET), shockwave lithotripsy (SWL), or ureteroscopy (URS)...

Ureteroscopy is a highly effective treatment for ureteral stones, characterized by a high stone-free rate and a low need for re-treatment. Ureteral stent placement can improve the insertion of the ureteral access sheath and ureteroscope but may be associated with higher morbidity prior to and after ureteroscopy. The study aimed to compare immediate versus post-stenting ureteroscopy for ureteral stone treatment in terms of operative time, intra- and post-operative complications, length of hospital stay, and stone-free rate...

BACKGROUND: We initiated a biomarker-informed preoperative study of infigratinib, a Fibroblast Growth Factor Receptor (FGFR) inhibitor, in patients with localized upper tract urothelial carcinoma (UTUC), a population with high unmet needs and tumor with a high frequency of FGFR3 alterations. METHODS: Patients with localized UTUC undergoing ureteroscopy (URS) or nephroureterectomy/ureterectomy (NU/U), were enrolled on a phase 1b trial (NCT04228042). Once-daily infigratinib 125 mg PO × 21 days (28-day cycle) was given for 2 cycles...

INTRODUCTION: The aim of this study was to perform an evaluation of patient experiences and perceptions regarding kidney stone surgery on the social media platform TikTok.

As well as demographic data such as gender and location, thematic content was also collected...

The purpose of this study was to evaluate the efficacy and safety of flexible ureteroscopy with holmium laser lithotripsy in the management of calyceal diverticular calculi. In this study, we retrospectively analyzed the clinical data of 27 patients with calyceal diverticular calculi admitted to the Department of Urology of the Zigong First People's Hospital from May 2018 to May 2021. Intraoperatively, the diverticular neck was found in all 27 patients, but flexible ureterorenoscopy lithotripsy was not performed in 2 cases because of the slender diverticular neck, and the success rate of the operation was 92...

Ureteral avulsion can be secondary to blunt or penetrating trauma, or can emerge as a surgical complication. Popularization of minimally invasive interventions has significantly decreased ureteral injuries, ranging from 0% to 28% and varying from minor mucosal injury to perforation, and most catastrophically, avulsion. We present a case of complete ureteral avulsion that was not initially appreciated after undergoing ureteroscopy for stone extraction. Eventual recognition of this injury was managed successfully with a subsequent laparoscopically nephrectomy and renal auto-transplantation preserving renal function...

Introduction Ureteral stents can cause significant patient discomfort, yet the temporal dynamics and impact on activities remain poorly characterized. We employed an automated tool to collect daily ecological momentary assessments (EMA) regarding pain and ability to work following ureteroscopy with stenting. Our aim was to assess feasability, and better characterize the postoperative patient experience. Methods As an exploratory endpoint within an ongoing clinical trial, patients undergoing ureteroscopy with stenting were asked to complete daily EMAs for 10 days postoperatively, or until the stent was removed...

BACKGROUND: Ureteropelvic junction obstruction (UPJO) is a common obstructive disease of the urinary tract. UPJO patients commonly exhibit coexistent renal calculi. The main aim of therapy is to relieve the obstruction and remove the stones at the same time. METHODS: This retrospective study included 110 patients diagnosed with UPJO coexisting with multiple renal calculi at Shanxi Bethune Hospital and the First Hospital of Shanxi Medical University between March 2016 and January 2022...

INTRODUCTION: High fluid temperatures have been seen in both in vitro and in vivo studies with laser lithotripsy, yet the thermal distribution within the renal parenchyma has not been well characterized. Additionally, the heat-sink effect of vascular perfusion remains uncertain. Our objectives were twofold: first, to measure renal tissue temperatures in response to laser activation in a calyx, and second, to assess the effect of vascular perfusion on renal tissue temperatures. METHODS: Ureteroscopy was performed in three porcine subjects with a prototype ureteroscope containing a temperature sensor at its tip...

INTRODUCTION: The Karl Storz FLEX-XC1 is a novel single-use flexible ureteroscope that uses the same videographics platform as its reusable digital counterpart. We evaluated the technical performance of the FLEX-XC1 in its initial clinical use. METHODS: We reviewed a series of consecutive ureteroscopy procedures performed by 2 endourologists using the FLEX-XC1 for indications for which we typically use a single-use device: total stone burden >15 mm or >10 mm in the lower pole, anticipated case duration >60 minutes, bilateral procedure, or upper tract urothelial cancer procedures...

BACKGROUND: Current approaches for diagnosis and monitoring of upper tract urothelial carcinoma (UTUC) are often invasive, costly, and not efficient for early-stage and low-grade tumors.
