A Comparison of Ureteroscopic Treatment of Nephrolithiasis With and Without Moses Technology
open to eligible people ages 18 years and up
Flexible ureteroscopy is characterized as first-line therapy for the treatment of renal stones < 2 cm in size. This involves passing a flexible endoscope into the renal pelvis through the urethra, bladder and ureter in a retrograde fashion. Holmium: YAG laser remains the preferred energy modality to subsequently break stones of this size into fragments small enough to remove or pass spontaneously through the ureter. Advances in the understanding of laser energy delivery have led to the recent commercialization of the "Moses Effect" - the creation of vapor bubbles/cavities between the laser fiber tip and the target through which laser energy can more efficiently travel. Lumenis was the first to optimize this laser phenomenon and market it as "Moses Technology" in their Lumenis Pulse P120H laser system. This system is already FDA approved through the 510K pathway and is commercially available. The purpose of this study is to evaluate the potential of Moses laser technology to reduce operative time compared to non-Moses settings for ureteroscopic treatment of nephrolithiasis.

Antibiotic Prophylaxis With Routine Ureteral Stent Removal
open to all eligible people
This study will be a single-institutional randomized, single-blinded prospectively controlled clinical trial of a single dose of Ciprofloxicin 500mg antibiotic tablet as prophylaxis at the time of office flexible cystoscopy with ureteral stent removal. The control group will be no prophylaxis oral antibiotics.

Break Wave(TM) Extracorporeal Lithotripter First-in-Human Study
open to eligible people ages 18 years and up
This is a prospective, open-label, multi-center, single-arm (non-randomized) study to assess the safety and effectiveness of breaking stones in the upper urinary tract using the SonoMotion Break Wave technology. Up to 30 subjects will be included. The procedure will be performed in a hospital surgical environment as an outpatient (without being admitted) or in a non-surgical environment such as a clinic or office procedure room. The procedure will be performed under varying levels of anesthesia ranging from no anesthesia to general anesthesia (fully asleep). Stones will be limited to ≤ 10 mm for lower pole stones and ≤ 20 mm everywhere else. Safety will be measured by the self-reported occurrences of adverse events, unplanned emergency department or clinic visits, and the need for further intervention. Fragmentation will be measured by self-reported stone passage and a comparison of computed tomography (CT) images before and after the procedure.

Endourology Disease Group Excellence (EDGE) Consortium: Antibiotics (Abx) for Percutaneous Nephrolithotomy (PCNL) Part 2
open to all eligible people
This study will be a multi-institutional randomized clinical trial of a short course of pre-operative antibiotic prophylaxis in addition to perioperative antibiotics prior to undergoing percutaneous nephrolithotomy. The select patient population will be those patients deemed to be at a moderately increased risk of postoperative infectious complications. These higher risk patients are those with indwelling urinary drainage tubes and those with a positive preoperative urine culture.

MIP Versus PCNL for Kidney Stone Disease
open to eligible people ages 18 years and up
The decision to use standard percutaneous nephrolithotomy (PCNL) versus mini-percutaneous nephrolithotomy (MIP) has been a subject of much debate in the urological community. The investigators propose a randomized controlled trial to compare the operative outcomes and complications of mini-percutaneous nephrolithotomy (mini-PCNL) versus standard PCNL for renal stones. The results of this study will help guide the decision making regarding these two procedures in the US population and provide further insight into the utility and safety of these procedures. A cost analysis will be performed, and it is hypothesized that the reusable components of the Storz MIP set will result in lower costs of the mini-PCNL procedure compared to standard PCNL.

Struvite Stones Antibiotic Study
open to eligible people ages 19 years and up
The aim of this research is to determine an effective antibiotic regimen following definitive surgical therapy of kidney stones caused by bacterial infection (struvite stones).

Ureteral Stent Placement After Ureteroscopy for Renal Stones: A Randomized Controlled Trial
open to eligible people ages 18 years and up
The rationale for this study is to determine if there is a difference in complications among patients undergoing ureteroscopy for renal stones who receive a stent compared to not receiving a stent postoperatively.

Asymptomatic Renal Calculi in Recurrent Urinary Tract Infections
open to eligible people ages 18 years and up
This study will assess patients who have recurrent urinary tract infections and kidney stones which are not blocking the kidney or causing other problems. Currently, we don't know if taking out these stones will improve recurrent urinary tract infections or not. Patients will make a decision with their surgeon about removing or monitoring their stone(s). Whether or not their infections continue with surgery or monitoring will be noted, and this information may help to inform future treatment decisions. The purpose of this study is to assess if treatment of these asymptomatic stones affects the rate of recurrent urinary tract infections.
