Filter by:Role Of Retrograde Intrarenal Surgery In Management Of Renal Stones: Single Center Experience
This study is designed to provide an evaluation of currently available disposable flexible ureteroscopes in real-world conditions. Due to high re-processing costs associated with re-usable flexible ureteroscopes, there has been a demand for Urologic device manufacturers to provide single-use flexible ureteroscopes.
- Reporting prevalence of uric acid based renal stones among patients with nephrolithiasis admitted to Mansoura Urology and Nephrology center (MUNC). - Furthermore, identification of monogenic and polygenic uric acid stone formers. - Identification of factors associated uric acid stone recurrence as well as determinants of laterality in patients with uric acid based renal stones
Conventional Percutaneous nephrolithotomy (PCNL) surgery requires the patient to first undergo retrograde transurethral ureteroscopic insertion of the ureteral catheter in the lithotomy position, and then change the patient to the prone position. However, repeated operation on the ureter can bring about immediate and long-term negative effects, such as ureteral false way formation, ureteral damage, perforation, avulsion, catheter insertion into the vena cava, pricking the kidney, increased postoperative pain, urinary extravasation, scar formation, and ureteral narrowing. The study planned to perform the operation in the prone position without reverse insertion of a ureteral catheter in the PCNL surgery.
This study aims to compare the efficacy and safety of both types of lasers, Holmium MOSES and TFL, in management of kidney stones requiring treatment.
To compare the efficacy of ultrasound-guided erector spinae plane block versus ultrasound-guided paravertebral block in pediatric patients undergoing percutaneous nephrolithotomy
Total tubeless Percutaneous nephrolithotomy (PCNL) is a modified surgical method of PCNL surgery, that is, there is no indwelling nephrostomy tube and double-J tube during PCNL surgery. Compared with traditional PCNL surgery, it has the advantages of reducing pain, shortening operation time and reducing operation cost. Since this procedure was first performed in 2004, several randomized clinical studies have verified the safety and efficacy of total tubeless PCNL. Conventional total tubeless PCNL surgery requires the patient to first undergo retrograde transurethral ureteroscopic insertion of the ureteral catheter in the lithotomy position, and then change the patient to the prone position. However, a large number of literature reports and the surgical experience of PCNL in the past 20 years tell the investigators that the reverse insertion of ureteral catheter can cause many recent surgical complications.The study planned to perform the operation in the prone position without reverse insertion of a ureteral catheter in the total tubular PCNL surgery.
The purpose of this study is to assess the accuracy of ultrasound and traditional fluoroscopy to find the residual fragments before retrograde intrarenal surgery is complete. This would ultimately limit the need for radiation exposure and improve the quality of clinical care given to patients and healthcare teams.
The extracorporeal shock wave lithotripsy (ESWL) is the treatment of choice for most stones in any of their locations. It is about breaking the stone without surgically intervening on the patient and getting him to expel the fragments himself. It is thought that additional treatments to the ESWL could improve the success rate of ESWL for less favorable stones. The components of our authorized food supplement have shown an inhibitory effect in vitro on the growth of calcium oxalate monohydrate crystals, even in hightly supersaturared solutions. Also these components show an inhibitory effect on the growth of calcium phosphate crystals. To sum up, it reduces the formation, inhibits the growth and promotes the dissolution of calcium oxalate and calcium phosphate kidney stones. This is the reason why this experimental study aims to modify the size limit of the stones in the ESWL with adjuvant food supplement.
We believe that kidney donors with kidney stones accepted for a donation do not have an increased risk of loss of kidney function and will not be at increased risk of symptomatic kidney stone events compared to donors without a history of kidney stones.
