Filter by:Objective: To improve quality-of-life and health care delivery to patients receiving ureteral stents. Specific Aims: Evaluate the feasibility, practicality, and qualitative outcomes of utilizing intra-nasal ketorolac in patients with indwelling ureteral stents (Phase I), followed by a randomized trial comparing two non-steroidal anti-inflammatory drugs, intra-nasal Ketorolac versus oral Diclofenac. Hypotheses: Due to its favorable pharmacokinetics in relieving acute pain, investigators expect improved pain scores and a lower rate of unplanned clinical encounters in patients receiving intra-nasal ketorolac compared to those taking oral diclofenac following ureteroscopic surgery for urolithiasis. Study Rationale: Following ureteroscopic management of urolithiasis, patient with indwelling ureter stents have higher levels of discomfort compared to those without a ureter stent. Prior studies showed that intramuscular Ketorolac at time of ureter stent removal decreased the incidence of unplanned clinical encounters. Furthermore, onset of analgesic effect by intra-nasal ketorolac is faster than its oral form, and similar its intramuscular and intravenous counterparts.
A qualitative research study conducted in hospitals across England, in which staff members will be interviewed. We will interview staff who are directly or indirectly involved in delivering care for patients undergoing the operations of interest; namely bladder tumour resection, prostate resection or enucleation, and ureteroscopy for upper urinary tract stones. We hope to find out the reasons why some hospitals can perform day-case surgery with very high rates, and why others do not. We also hope to find out about any unexpected outcomes observed when performing day-case surgery for the operations of interest. Staff working in a range of different hospitals from across England with varying day-case rates will be interviewed. Hospitals in large city and more rural areas will be assessed. Interviews are anticipated to take place over a six month period. The study will end when "saturation" is achieved, whereby no new themes are identified through interviews. Saturation will be sought for each individual operation of interest.
To evaluate the efficacy and safety of electroconductive (EC) and electrohydraulic (EH) extracorporeal shock wave lithotripsy (ESWL) for the treatment of ureter and kidney stones, this study conducted a randomized controlled trial.
The aim of this study is to assess the quality of life (QoL) in pediatric patients with urinary stone disease.
This is a prospective randomized controlled trial designed to assess the differences in postoperative symptoms related to placement of a 6Fr Percuflex ureteral stents, 6Fr Tria ureteral stents, and 4.8Fr Tria ureteral stents after ureteroscopy with laser lithotripsy for treatment of upper tract urinary stones. 192 participants will be enrolled and will be on study for up to approximately 10 weeks.
The incidence of stone disease of the urinary tract in children is increasingly increasing with a remarkable economic impact for its management. This incidence is variable according to race, geographic region, socio-economic status and dietary habits. Oxalo-calcium stones are the most common but the biochemical nature of urinary stones varies depending on the region where those of a phosphatic nature are characterized by a higher incidence in Europe. The diagnosis is confirmed by imaging. The unprepared abdomen (ASP) has low diagnostic accuracy. The scanner is the reference tool but remains an irradiating examination. Risk factors for disease recurrence include primarily the presence of an underlying urinary metabolic abnormality and young age. Urinary metabolic abnormalities vary from one study to another. The understanding of lithogenesis, its evaluation as well as the therapeutic options is essential for adequate and adapted management in the pediatric population.

To Compare the safety and efficacy of PNL in a modified flank-free supine position versus prone position in pediatric patients
The purpose of the study is to investigate whether the use of gentamicin-based irrigation fluid during ureteroscopy decreases the risk of UTIs and other post-operative infections after surgery.
This study tests whether hydroxycitrate, a molecule closely related to citrate, can reduce calcium phosphate stone recurrence.
