INTRODUCTION: Ureteral stents-related symptoms (USRs) are the common complications of ureteral stenting. Tamsulosin a selective alpha-1 blocker and Tadalafil a PDE-5 inhibitor are one of drugs have been used for USRs relief. In this study we aimed to evaluate the effectiveness and safety of combination therapy Tamsulosin+Tadalafil for treating USRs comparing it with the efficacy of either Tamsulosin or Tadalafil monotherapies. MATERIAL AND METHODS: 279 patients with indwelled unilateral ureteral stents were randomized to Tamsulosin 0...

INTRODUCTION: Despite the developments in the material of the double J (DJ) stents and the production of thinner ones of desired sizes, patients continue to experience troublesome DJ stent-related symptoms in their lives. This study aimed to determine how DJ stenting affects patients' work performance after endoscopic stone surgery. MATERIAL AND METHODS: A total of 107 patients underwent placement of a ureteral stent after ureterorenoscopy (URS)/retrograde intrarenal surgery (RIRS), and only active and full-time working patients were included...

PURPOSE: To compare stent-related symptoms (SRS) in patients with double J (DJ) undergoing substitution with a pigtail suture stent (PSS) after ureteroscopy (URS), through the Ureteral Stent Symptom Questionnaire (USSQ). MATERIALS AND METHODS: Patients with DJ undergoing URS for stone treatment were enrolled in this prospective multicenter longitudinal study. The USSQ was submitted thrice: 2 weeks after DJ, 2 weeks after PSS and 4 weeks after PSS removal (baseline)...

BACKGROUND: In urology, ureteral stents are used to treat obstructive diseases. Hematuria (54%), fever, discomfort, and lower urinary system symptoms are the predominant symptoms related to ureteral stent. AIM: This article links stent symptoms to double-j width and length, as well as patient's height, weight, and body mass index (BMI). Ureteric Stent Symptoms Questionnaire (USSQ) was used to measure ureteral stent symptoms at 1st and 4th week of stent in situ as well as the 4th week after pigtail removal...

OBJECTIVE: To assess efficacy, comfort, and symptoms of a novel ureteral stent (RELIEF) substituting the distal semirigid coil of a traditional double-J for a floating, monofilament tether allowing coaptation of the ureteral orifice. Ureteral instrumentation notoriously cause discomfort, urgency, frequency, dysuria, and hematuria; prolonged morbidity is likely related to stent-associated vesicoureteral reflux (VUR). We hypothesized this design would eliminate VUR, be safe and provide comfort following intervention...

Group A with threads through the urethra and Group B through the percutaneous tract. The validated USSQ (Ureteral Stent Symptom Questionnaire) was applied in the Urology office a week after the procedure, and the JJ stent was withdrawn by pulling the threads...

OBJECTIVE: To compare the stent-related symptoms (SRS) of three commonly used, readily accessible ureteric JJ stents after uncomplicated flexible ureteroscopic lithotripsy (FURL), in a prospective randomised controlled single-blind parallel-group study, in order to see whether structural difference might influence SRS. PATIENTS AND METHODS: Patients undergoing FURL were randomised into three groups: the Cook Group received conventional 6 F Cook Universa Soft JJ stents as control, the Kang Yi Bo (KYB) Group received 6 F KYB anti-reflux JJ stents, and the Urovision Group received 7 F Urovision Visiostar ESWL JJ stents...

Introduction Alpha-adrenergic blockers like tamsulosin are widely used in the treatment of stent-related symptoms due to ureteric stents. Recently, mirabegron has emerged as a potential alternative. So, our study aimed to compare the effect of mirabegron and tamsulosin on ureteric stent-related morbidity. Methods In this randomized controlled study, 80 patients undergoing uncomplicated ureteroscopic lithotripsy with double J stenting for ureteric stones were enrolled. They were divided into two groups: Group A (n=40) received mirabegron (25mg) and Group B (n=40) received tamsulosin (0...

INTRODUCTION: Up to 80% of stent patients report urinary discomfort, negatively impacting their daily activities and quality of life. Conventional double-J ureteral stents (DJS) can cause adverse kidney and bladder-related symptoms. Completely intraureteral stents (CIS) may reduce bothersome bladder symptoms by reducing foreign material in the bladder. We sought to aggregate and analyze ureteral stent symptom questionnaire (USSQ) data from the available randomized controlled trials comparing CIS with conventional ureteral stents...

INTRODUCTION: Double-j (DJ) ureteral stents are used for multiple purposes in Urology. Even though they temporize the subsequent treatment of lithiasis, they may cause different symptoms that impact quality of life. PURPOSE: in this randomized trial we assessed whether the diameter of ureteral stents has an impact on catheter-associated symptoms, and their impact on quality of life. METHODS: A total of 194 consecutive patients undergoing DJ insertion between December 2018 and December 2022 were prospectively enrolled and divided into three categories: 4...

Objective: We conducted a meta-analysis to assess the efficacy and safety of mirabegron (50 mg/day) and antimuscarinics in treating ureteral stent-related symptoms (SRSs). Methods: All randomized controlled trials (RCTs) were identified by searching PubMed, Embase, Web of Science, and Cochrane Library. The RevMan version 5.3.0 software was used for statistical analysis. Results: This meta-analysis included five RCTs involving 317 patients. A fixed effects model revealed that mirabegron was superior to antimuscarinics in treating urinary symptoms (MD -1...

Objectives: To determine whether urinary symptoms are significantly improved with a shorter duration of stent placement without an increase in complications. Methods: A total of 100 patients were prospectively randomized to two groups, either a 3-day ( n  = 59, Group 1) or 7-day ( n  = 41, Group 2) stent placement group depending on date of operation. Patients submitted Ureteral Stent Symptom Questionnaires both while stents were in situ and 2 to 3 days after removal. Results: Group 2 reported greater urinary symptoms ( p  < 0...

OBJECTIVE: To explore the impacts of delayed ureteral stent removal on the quality of life (QoL) and mental health of urinary calculi postoperative patients due to the corona virus disease 2019(COVID-19) pandemic. METHODS: The demographic and clinical data of patients with ureteral stent placement after urinary endoscopic lithotripsy and returned to Peking University People's Hospital for stent removal from December 2019 to June 2020 were collected.
