Active clinical trials for "Kidney Calculi"

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.

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 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.

Role Of Retrograde Intrarenal Surgery In Management Of Renal Stones: Single Center Experience

Prior studies have shown that the source of dietary protein can have a significant impact on urinary stone risk. However, whey and plant protein isolates have not been compared. This is an important distinction as protein supplements fortified foods are increasingly popular. Herein, we seek to investigate the effect of different protein supplements, in an otherwise identical diet, on urinary stone risk.

This is a randomized control trial comparing oral ketorolac and opioid medication for the use of post-operative analgesia.

This is a randomized prospective study to compare stone free rates and operative efficiency of two laser systems used during retrograde intrarenal surgery for kidney stone disease: A superpulsed thulium fiber laser (thulium) A pulse modulated high power holmium laser (Holmium)

This multi-center trial is being completed to compare patient outcomes related to the Imajin silicone stent in comparison to non-silicone polyurethane stents after ureteroscopy. Eligible participants will be enrolled and randomly assigned to receive the Imajin silicone stent or a non-silicone stent. In addition, the participants will complete questionnaires and have follow-up information collected (approximately 60 days after surgery). The trial hypothesizes that a ureteral stent made of silicone, will have superior outcomes when compared to non-silicone stents.

Advancements in technology and endourological armamentarium provides multiple surgical options for complicated stone patients. To avoid multiple operations and shorten the total operation durations, bilateral synchronous simultaneous stone surgery (BSSSS) has been popularized in recent years. Our aim is to evaluate the preliminary outcomes of BSSSS in patients undergoing supine percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS).

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.
