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
This research study is to determine how well the Erector Spinae Plane Block (ESPB) works for kidney stone pain and any possible side effects.
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.
This is a prospective controlled study to compare the efficacy and safety of two methods of flexible urethroscopy in patients with urolithiasis, as well as the effect of surgery on quality of life.
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.
