Filter by:To investigate the effectiveness of percutaneous nephrostomy catheter placement versus retrograde double J catheter placement in patients with symptoms of obstructive kidney disease (with either infection and/or pain and/or kidney function deterioration) caused by urolithiasis.
60 patients Inclusion Criteria: - age from 18 to 70 years - Indications for mini-PCNL - ASA score: 1-3 - Single percutaneous access to pyelocaliceal system - Size of solitary calculus up to 2.5 cm Exclusion Criteria: - Active urinary tract infection - Coagulopathy - Clinically significant infravesical obstruction (Qmax less than 10 ml / s, PVR more than 50 ml)
A pivotal study to evaluate the safety and effectiveness of Applaud Acoustic Enhancer when used in conjunction with conventional ureteroscopic laser lithotripsy (URS-LL) in the treatment of subjects with urinary stones.
The aim of the study was to compare the ultrastructural changes in the renal parenchyma with the results of postprocessing CT analysis with contrast enhancement in patients with urolithiasis.
Urolithiasis has an increasing incidence and prevalence worldwide, and some patients may have multiple recurrences. Because these stone-related episodes may lead to multiple diagnostic examinations requiring ionizing radiation, urolithiasis is a natural target for dose reduction efforts. Abdominopelvic low dose CT, which has the highest sensitivity and specificity among available imaging modalities, is the most appropriate diagnostic exam for this pathology. The main objective of this study is to evaluate the diagnostic performance of ultra-low dose CT using deep learning-based reconstruction in urolithiasis patients.
The purpose of this study is to determine if CBD oil has any effect on decreasing postoperative pain control following ureteroscopy for urinary stone disease, and to determine if CBD oil has any effect in decreasing the amount of postoperative opioids (commonly used drug) used by patients after undergoing ureteroscopy for urinary stone disease.
Despite the advent of treating stones with Extracorporeal Shock Wave Lithotripsy (ESWL) and Percutaneous nephrolithotomy (PCNL), the recurrence rate for renal stones remains high and this may be due to poor compliance of patients with dietary and fluid advice, age, metabolic abnormalities, medicines and the formation of "new stones" from clinically insignificant residual fragments (CIRF). Though some patients become stone-free after ESWL/PCNL or open surgeries, the majority develop "new stones" and it is difficult to predict when these stones will recur until either they have imaging perform or they developed symptoms. However, the use of regular imaging for monitoring will be costly and involve radiation exposure. Therefore, a diagnostic tool is needed to enable the clinician and/or patient to monitor for stone recurrence. In the previous studies, some urine markers were identified that are related to stone formation. The relationship of these urine markers with the recurrence of renal stone will be further explore in this study. Also, potential markers that could predict stone recurrence will be identified, and hence earlier intervention could be offered to patients.
Obstructing urolithiasis can be life-threatening in the setting of urinary tract infection. The purpose of this study is to identify and validate risk factors and markers for the presence of infection and development of sepsis among patients with obstructing urolithiasis.
Prospective study is to compare between different nephrolithometric scoring systems in prediction of PCNL outcomes in terms of efficacy , success rate and safety in Adult patients with UUT stones unilateral or bilateral, single or multiple, Pelvic or calyceal, primary or recurrent, both gender attending Assuit Urology & Nephrology University Hospital.
This is a prospective randomized double-blind controlled trial assessing the benefits of intramuscular ketorolac before or immediately after office ureteral stent removal.
