Impact Ureteral Sheath Design During Ureteroscopy

Renal StoneNephrolithiasis1 more

The purpose of this study is to assess whether one of two ureteral access sheaths is safer for patients undergoing ureteroscopy. Both sheaths are FDA approved devices and commercially available. The investigators will compare the ability of sheaths to access the kidney through the ureter and will compare damage done to the ureter after completion of the procedure. Access sheaths are standard of care for this procedure; this study seeks to optimize outcomes for patients. Patients undergoing ureteroscopy who do not have ureteral stents in place and who have not had an ipsilateral procedure within 90 days will be recruited and consented.

Evaluation of Pain Before and After Removal of Non-obstructive Kidney Stones

Kidney Stone

Pain associated with renal stone disease is typically caused by an obstructing stone that obstructs the flow of urine, which results in renal collecting system dilatation. Non-obstructing renal calculi that do not cause renal collecting system dilatation are thought to be painless. The objective of this study is to prospectively determine if the removal of non-obstructing renal calculi can reduce or eliminate participant's pain and/or improve their quality of life.

Intraoperative Cone-beam CT for Percutaneous Nephrolithotomy

Nephrolithiasis

Percutaneous nephrolithotomy (PCNL) is a first-line treatment for kidney stones >2cm. Frequently, patients require multiple procedures to address their stone burden. The decision to proceed with a second-look procedure is based on follow-up CT imaging, which is obtained postoperatively. In this study, we propose the use of a portable CT scan technology to obtain follow-up imaging while the patient is still under anesthesia for the initial procedure. The goal of this study is to determine whether this allows the surgeon to identify residual fragments and render the patient stone-free within a single anesthetic event.

Effect of Tamsulosin on Stone Expulsion and Pain Resolution in ED Patients With Ureterolithiasis...

Kidney Stone

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.
