Filter by:To determine whether pyridoxamine can decrease oxalate excretion in subjects who have normal oxalate excretion (but who have had kidney stones), and in subjects who have primary hyperoxaluria.
The purpose of this study is to determine if there is a role of prophylactic therapy with tamsulosin prior extracorporeal shock wave lithotripsy to avoid development of steinstrasse. 150 persons that will go to Extracorporeal shock wave lithotripsy will randomize to 2 groups. Group 1 -of 75 persons will recieve tamsulosin 0.4 mg x 1/d 2 days before the lithotripsy . Group 2 - of 75 persons will not recieve tamsulosin. 48 hour after the ESWL all 2 group will take abdominal radiograph to evaluate the presence of steinstrasse.
To determine if emergency department patients with acute ureteral colic pain due to a ureteral stone who are treated with tamsulosin, versus placebo, will experience a shorter time to passage of their stone or resolution of their pain. A secondary study objective will be to determine if there is a relationship between response to tamsulosin and stone size or position in the ureter.
The purpose of the study is to examine the effect of endoluminally administrated isoproterenol on pelvic pressure increase during flexible ureterorenoscopy in 14 humans. We propose that isoproterenol has potential of reducing intrarenal pressure during ureterorenoscopies. Lower intrarenal pressures may have the advantage of facilitating the procedure and reducing intraoperative complications as bleeding and infections.
The patient will be asked to participate in a research project designed to determine the best way to prevent bleeding and promote patient comfort after having kidney stones removed. Two standard methods for ending the surgery are being compared to a newer method. In one standard method, the patient will have a tube draining urine from the kidney after the procedure. This tube may also prevent bleeding from the kidney. In another standard method the patient will have a tube left internally that drains urine from the kidney to the bladder and a stitch will be used to close the incision and deeper tissues in the back. In the third potential option, a tube would be left internally to drain urine from the kidney to the patient's bladder and the surgical site would be filled with a clot promoting agent (FloSeal) which is a FDA approved agent specifically formulated to stop bleeding during surgical procedures.
Percutaneous nephrolithotomy (PNL), in conjunction with intracorporeal lithotripsy, allows for the rapid removal of any kidney stone regardless of size. Currently, the choice of intracorporeal lithotripters includes ultrasonic, pneumatic, and combined ultrasonic/pneumatic energy sources. Recently, a novel dual probe design as been introduced by Cybersonics of Erie, Pennsylvania. This dual probe intracorporeal lithotrite is called the Cyberwand, and is composed of a fixed inner probe vibrating at an ultrasonic frequency with an outer probe vibrating at about 1,000 Hz. As this new design has the potential to revolutionize intracorporeal lithotripsy, we intend to compare this novel technology to currently available lithotripsy technology in a randomized clinical trial.
Is it possible to decrease the intrarenal pressure in the kidney during endoscopic management of kidney stone by topical administration of drugs? In order to secure fewer complications in ureteroscopic operations the pharmacological agent isoproterenol is tested on pigs and human to determine its potential of lowering intrarenal pressure.
The purpose of this study is to determine whether Tramadol Hcl is as effective as Voltaren a non-steroidal antiinflammatory drug, and Dipyrone in amelioration of the pain caused by acute renal colic.
Examine the effects of cola on risks of kidney stones
The Study of whether or not Ureteral Stent Length affects patient comfort after electro-shock wave treatment for kidney stones.
