Filter by:This research aims to study the effectiveness of silodosin in the management of lower ureter stones larger than 6 mm in diameter in terms of affected ureter (right or left), the size of the stone, the degree of hydronephrosis, the rate of stone expulsion(day), whether the stone was completely expelled or not, and the side effects of silodosin.
a prospective comparative study designed to compare the outcomes of transperitoneal Laparoscopic ureterolithotomy (T-LUL), mini-percutaneous antegrade ureteroscopy (A-URS) and retrograde ureteroscopy (R-URS) in treating patients with LPUS (15-20 mm). the following parameters were assessed and compared (demographic data and stones characteristics, Stone free rate and complications)
With advances in endourological equipment, minimally invasive procedures have been found to be sufficient for the treatment of ureteral stones in children. The investigators aimed to evaluate the stone-free rate and complications related to the procedure and to compare it with the period when their experience were limited by presenting their patients with ureteral stones treated by ureteroscopy (URS) and holmium YAG laser in the last three years after their 15-year routine endourological practice. The investigators retrospectively compared 54 cases treated with ureteroscopy (URS) for ureteral stones between 2009-2011, the first three years of our endourological interventions in children, and 78 cases treated with URS for ureteral stones between 2020-2022, the last three years of their 15-year endourological experience, from hospital records. Demographic data, stone-free rates, number of procedures and recorded complications were evaluated in both groups.
Double J stent (ureteral stent) can cause discomfort to patients, generally due to irritation of the bladder mucosa, especially in the trigone area, smooth muscle spasm, and reflux of urine into the ureter. Complaints often appear in patients, especially lower urinary tract symptoms (LUTS), pain in the waist when urinating due to reflux of urine, sexual dysfunction, and hematuria. Currently, to assess complaints after ureteral stent placement, the Ureteral Stent Symptom Questionnaire instrument consists of 6 topics: urinary complaints, pain, general health, work, sexual problems, and other things. Interleukin-6 is an important inflammatory cytokine when irritation occurs after ureteral stent placement. Interleukin 10 is a cytokine with potent anti-inflammatory properties that plays a central role in limiting the host's immune response to pathogens, thereby preventing host damage and maintaining normal tissue homeostasis. The profile of these biomarkers has the potential to determine the correct prognosis and therapy. Mirabegron is a β3 adrenergic receptor agonist that has a dual antioxidant effect that plays a key role in the first step of the antimicrobial response and early resolution of inflammation so that post-stent complaints similar to overactive bladder complaints can be resolved. Tamsulosin (a selective α1A- and α1D-adrenoceptor antagonist) has a relaxing effect on the smooth muscle in the prostate, the neck of the bladder, and the distal ureter, thereby reducing the inflammatory reaction and improving oxidative stress by reducing the formation of reactive oxidative stress.
Objective: To observe the effect of Ningmitai capsule on ureteral calculi after lithotripsy and evaluate the safety of treatment. Study Design: A multicenter, prospective, randomized, controlled clinical study design was adopted Interventions: control group: Give antibiotics or diclofenac sodium suppository as needed. Ningmitai group: Oral Ningmitai Capsule (produced by Guiyang Xintian Pharmaceutical Co., Ltd.), 0.38 g/capsule, 4 capsules each time, 3 times a day. combination group (Ningmitai plus tamsulosin).: Tamsulosin capsules, 0.2 mg/capsule, one capsule each time, once a day, were taken on the basis of Ningmitai group.
The aim of this prospective comparative clinical study to compare DJ stenting and Sildosin after ureteroscopic lithotripsy for lower ureteric stones.
to compare efficacy and safety of Silodosin and Tamsulosin in Medical expulsive therapy of Distal Ureteric Calculi.
This study will compare the efficacy of silodosin, tadalafil versus silodosin plus tadalafil as Medical Expulsive Therapy (MET) for lower ureteric stones.
Extracorporeal shock wave lithotripsy (ESWL) is the least invasive and effective treatment for upper ureteric stones with a stone clearance rate of 60-90%. Tamsulosin is an alpha-blocker widely used in urological practice to relax smooth muscle of the prostate and bladder neck. Its role as part of medical expulsion therapy for the treatment of patients with kidney and ureteric stones has proved to be of considerable success. However, its role in clearing upper ureteric stones as an adjunct to ESWL is controversial. Therefore, this study will be conducted to evaluate its role in stone clearance along with extracorporeal shock wave lithotripsy in patients with upper ureteric stones
The primary aim of this study is to investigate the temperature profiles in the renal pelvis during ureteroscopic Thulium Fiber Laser activation using different settings. To this end, comparison of peak temperatures during laser activation for different settings is the main aim. Secondary aim is trying to define the duration of safe laser activation until the threshold for heat induced cell injury (43oC) is reach. Patients ≥ 18 years with a ureteral stone (with or without a concomitant renal stone) and an indwelling nephrostomy tube scheduled for ureteroscopic lithotripsy at the day surgery unit at Haukeland University Hospital, are eligible to enrolment in the study. Temperature measurements during ureteroscopic laser stone disintegration will be performed. Follow-up is standardised with clinical consultation and low dose CT 3 months post endoscopically.
