Filter by:The investigators main hypothesis is that the stone free rate will be much higher (95%) in patients treated with PCNL than patients treated with ESWL where stone free rate is (60%) to determine which treatment is safe and prevent less stone recurrence.
The objectives of the study are to assess the systemic exposure, safety and efficacy of three concentrations of OMS201 in subjects undergoing retrograde ureteroscopic removal of upper urinary tract stones.
The purpose of this study is to investigate the effect of oxynorm versus morphine after operation for kidney stone (PCNL). In addition the relationship between pain symptoms and referred sensory and trophic changes will be examined in the patients before and after the operation.Finally a blood sample is analysed to investigate pharmaca-genetics.
The purpose of this study is to determine whether continuous intravenous ketorolac infusion reduces pain in patients who are having percutaneous nephrolithotomy for kidney stone disease.
Tamsulosin (Flowmax)is approved by the FDA for the treatment for enlarged prostate. Several studies regarding the use of Tamsulosin for the treatment of lower kidney stones have been carried out in the non-Emergency Department setting. This study will compare Tamsulosin 0.4 mg with placebo in regards to rate and time of stone passing and will also look at amount of pain. The purpose of this study is to compare the usefulness of Tamsulosin versus placebo on time to stone passage and pain relief in Emergency Department patients with kidney stones.
An analgesia protocol for acute renal colic will lead to faster significant reductions in pain than prior practice.
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.
