Filter by:The aim of the work is to compare the efficacy of tadalafil and tamsulosin as a medical expulsive therapy for lower ureteric stones
Randomized comparison of patient outcomes following fluoroscopic guided PCNL versus ultrasound-guided PCNL.
Ureteric calculi are one of the most common reasons for frequent Urolithiasis. The estimated prevalence is 8-13% of all calculi. Medical expulsive therapy (MET) is recommended by the European Association of Urology (EAU) (2013) for 5-10 mm ureteric stones to facilitate stone passage. For MET, alpha blockers, mainly tamsulosin, have shown efficacy in several randomized controlled trials. The underlying pathophysiology of this therapy is supported by the presence and distribution of adrenoreceptors in the ureter. Blocking the action of alpha-1 receptors by pharmacological agents (alpha blockers), such as alfuzosin, terazosin, doxazosin, and, most typically, tamsulosin, results in the relaxation of the ureteric smooth muscle. Ureteroscopy (URS) is the most commonly performed procedure for the treatment of ureteral calculi, with a high (>90%) stone-free rate after a single treatment. Advancing a rigid ureteroscope into a non-dilated ureter may be difficult and cause complications. Ureteric dilatation may provide access to stones, but not in all cases, and ureteral mucosal injury up to perforation might occur.
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.
Ureteral stone is a common disease with high prevalence and recurrence rate in Taiwan. Taiwan is located in subtropical zone, where urolithiasis is commonly seen. A national survey in Taiwan determined that 9.6% of the population suffered stones throughout their lifetime. Symptoms of ureteral stone include renal colic, hematuria, and urinary tract infection. Without proper treatment, ureteral stone could lead to renal function impairment such as acute kidney injury (AKI) or chronic kidney disease (CKD). There are several treatment options for ureteral stone, such as ureteroscopic lithotripsy (URSL), flexible urteroscopic lithotripsy (F-URSL), percutaneous nephrolithotomy (PCNL), extracorporeal shock wave lithotripsy (ESWL), and Medical expulsive therapy (MET). However, there are only few minutes from diagnosis of ureteral stone to possible treatment options explanation. It's difficult for patients to well understand all the details of possible treatments under such circumstances. Therefore, we design a patient decision aid (PDA) for unilateral ureteral stone to help patients understand all the treatment options. The PDA is standardized, written in plain language and patient-centered, with pictures attached.
The use of Laryngeal masks are increased.This study aimed to compare lma pro seal and baska -mask in urethral retrograde sistoscopy operations.
This study aims to compare three groups of patients who underwent uncomplicated ureteroscopic lithotripsy (URSL) to evaluate whether stents could be eliminated after the procedure
