Filter by: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.
This prospective randomized clinical trial aimed to compare the difference in stone ablation rates of TFL and Ho:YAG laser in a clinical setting. Patients are randomized to receive URS with lithotripsy (URSL) either with TFL or Ho:YAG with an allocation ratio of 1:1. Primary outcome is the efficiency of stone ablation in terms of the stone ablation rate
The investigators will assess the use of Transcutaneous Neurostimulation (TENS), a pharmacological alternative, for treatment of ureteral stent pain post-ureteroscopy. The primary aim for the investigators is to determine if use of a TENS unit will reduce post-operative pain and nausea associated with the ureteral stent. Secondary aim will be to assess if it can help minimize narcotic use.
This study investigated a previously unassessed operating position for ureteroscopic holmium laser lithotripsy in patients with upper ureteral stone. The reverse Trendelenburg position can reduce migration and improve the stone free rate (SFR). Moreover, less utilization of flexible ureteroscope and hospital stay in reverse Trendelenburg position can reduce the medical cost. Therefore, it can be safely used as an optional surgical method for the treatment of upper ureteral stones.
Given the high recurrence of urolithiasis in patients, the search for less aggressive and preventive treatments is increasingly necessary. Renalof® is presented as an alternative to herbal medicine being a product that, due to its diuretic and demineralization properties of kidney stones, has been widely used in this patient population, disintegrating and eliminating calcium oxalate and struvite stones in a painless in the genitourinary system. With the objective of determining the efficacy of this therapy, an observational, prospective, randomized, single-blind, two-arm study was carried out: treatment group with Renalof® and control group, placebo.
To assess the efficacy of peri-operative alpha1 blockers on improving the success rate and decreasing complications of non-stented ureteroscopic laser lithotripsy for ureteric stones.
The purpose of this study is to collect real-world evidence on the performance of the SOLTIVE™ Premium SuperPulsed Laser System for laser lithotripsy in ureteroscopy, percutaneous nephrolithotomy (PCNL) and mini PCNL for kidney and ureteral stones.
To evaluate the effect of masturbation on the spontaneous expulsion of distal ureteral stones 5-10 mm in size.
The use of Laryngeal masks are increased.This study aimed to compare lma pro seal and baska -mask in urethral retrograde sistoscopy operations.
