Filter by:In this study, the investigators aim to evaluate the intervention preferences of patients with obstructive urinary stones who are suitable for operation during the COVID-19 pandemic. The secondary aim is to compare and evaluate the preferences compared to the pre-pandemic period and to gain a perspective on how the decision-making process has changed from the patient's point of view. Thus, by trying to understand how the COVID-19 epidemic affects the treatment choice decisions of patients, the investigators aim to determine how the state of anxiety changes these preferences.
Indwelling double-J ureteral stent (D-J stent) are routinely placed in patients who received ureteroscopic lithotripsy (URL) in Xinhua Hospital Urology Department. At present, three types of D-J stents, namely Cook/Kang Yi Bo(KYB)/Urovisionare are used, and usually removed in the day ward four weeks after surgery. This study intends to randomly divide patients with urolithiasis based on the preoperative OABSS (overactive bladder symptom score) questionnaire into three groups, namely Cook D-J stent group, KYB anti-reflux D-J stent group, Urovision trigonal D-J stent group, with corresponding D-J stent indwelled for 4 weeks respectively. The patient's USSQ ureteral stent symptom questionnaire）scale and OABSS scale were collected at 1 week, 4 weeks (before the removal of D-J stents), and 5 weeks (1 week after removal of D-J stents) after URL operation, and the D-J stents removed from the patients were collected, and their drainage and anti-reflux effects were measured in vitro.
The femur or thigh bone is the strongest and longest bone of the body and about 45 cm long in an average man that means approximately one fourth of the height of individual. It has upper end, lower end and a cylindrical shaft. Upper end consists of head, neck. The neck is about 5 cm long, connects the head to the shaft and is directed upward, medially and slightly forward and making an angle about 125 with shaft but the angle is wider in children. The neck-shaft angle (NSA ) is defined as the angle formed by the neck axis and long axis of the shaft of femur.The knowledge of the neck shaft angle is valuable in the diagnosis and treatment of fracture of upper end of femur. The aim of the study is : 1. to evaluate the normal values of femoral neck-shaft angle 2. to detect factors that may affect this angle as age, and sex, in Egyptian adults from Sohag.
This is a prospective, open-label, multi-center study to test the clinical feasibility of facilitating stone passage by the combination of breaking and repositioning stones with ultrasound, without the need for anesthesia.
This study is intended to be a prospective registry of patients undergoing any kind of stone treatment that have a pre-operative CT available. This imaging will be used to measure the stone burden in three different ways: in a single dimension (cumulative stone diameter), in two dimensions (surface area) and in three dimensions (volume).The primary purpose is to identify what way of measuring stone burden is most predictive of outcomes after stone treatment such as stone free status, operative time and complications.
This study will investigate the effect of a patented high citrate beverage on urine chemistry in patients with urinary stone disease (USD). It is a minimal risk study of an over-the-counter beverage called Moonstone, which is commercially available. This study is considered preparatory for the RO-1 and is not intended to produce a definitive outcome regarding kidney 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.
The purpose of the study is to identify bacterial and fungal microbiome associated with calcium oxalate (CO) urolithiasis and renal cell carcinoma (RCC).
The aim of the study is to compare URS lithotripsy performed with Holmium:YAG laser and Thulium Fiber Laser. The study is designed as a prospective clinical randomised trial, where the study participants are randomised to either URS with Holmium:YAG laser or URS with Thulium Fiber Laser. The outcomes of the URS procedures are compared for the two treatment arms.
The investigators would like to assess if the intake of high bicarbonate mineral water would not only increase total fluid intake but will also be able to give patients the additional benefit of correcting the urinary abnormalities which may predispose them to stone formation.
