Filter by:The study is a randomised trial of hypnosis with 3D virtual reality headset (intervention group) versus control group with no hypnosis and no virtual reality headset to compare remifentanil consumption during shock wave lithotripsy.
The optimal management of medium-sized renal stones remains quite challenging and continues to be contested. In the present study, the investigators will compare mini-PNL, RIRS and SWL in the treatment of non- lower pole, medium size, high dense renal stones regarding the stone-free rate, the safety of the procedures, cost, and patients' and surgeon's satisfaction. Eligible patients will be randomly allocated into three equal groups (mini-PNL, RIRS, and SWL). Postoperative, patients will be followed-up by regularly for 3 months. The study parameters will be compared between groups.
Percutaneous nephrolithotomy (PCNL) is the preferred treatment for renal stones >2 cm or resistant to ESWL. Postoperative pain following this invasive surgery adds to the morbidity of patient which requires additional analgesia and can affect the quality of care. To lower the morbidity of PCNL, proper and adequate management of postoperative pain remains an integral component of PCNL. There are many ways to reduce the postoperative pain following PCNL including mini PCNL, tubeless PCNL, use of regional analgesia etc. However the modality of analgesic technique is still a matter of debate. The aim of this study is to evaluate the efficacy of intercostal nerve block compared with peritract infiltration in patient undergoing PCNL. Specifically, the study will look on to the demography of patients undergoing PCNL and their indications. The study will also compare the intensity of pain in two groups using visual analogue scale (VAS). The study will be a prospective double blinded randomized clinical trial done at Department of Urology and Kidney Transplant Surgery, Tribhuvan University Teaching hospital (TUTH). The time frame of this study will be of 1 year or when sample size is fulfilled including all the patients who visit the hospital for PCNL and fulfils the inclusion criteria. At the end of our study we expect to conclude that the use of intercostal nerve block is superior or inferior than or equal to peritract infiltration in alleviating the postoperative pain following PCNL.
currently, percutaneous nephrolithotomy (PCNL) is the standard procedure of choice for management of large renal more than 2 cm. the pivotal step in performing PCNL is creation of proper tract. this step can be done monitored under guidance of different modalities such as fluoroscopy, ultrasonography, endoscopy or combined in ECIRS, tract creation is controlled under endoscopic vision with a flexible ureteroscope .
Urolithiasis is a common health problem worldwide affecting approximately 10% of the population at some stage in their lives. The aim of this study is to evaluate the efficacy of adjuvant treatment with tamsulosin for improving the stone-free rate after a single session of extracorporeal shock wave lithotripsy (ESWL) in the treatment of radiopaque kidney stones.
Percutaneous nephrolithotomy (PCNL) is considered to be the first choice and a more conservative procedure than open stone surgery. Not only postoperative pain related to dilatation of the renal capsule and parenchymal tract, but also patient's discomfort & nephrostomy tube-related stress are reported to delay recovery time and increase the complication rates. This study is designed to provide postoperative analgesia by using ultrasound-guided continuous Quadratus Lumborum Block (QLB) III in patients undergoing PCNL and to assess pain scores & side effects with less opioids consumption.
The decision to use standard percutaneous nephrolithotomy (PCNL) versus mini-percutaneous nephrolithotomy (MIP) has been a subject of much debate in the urological community. The investigators propose a randomized controlled trial to compare the operative outcomes and complications of mini-percutaneous nephrolithotomy (mini-PCNL) versus standard PCNL for renal stones. The results of this study will help guide the decision making regarding these two procedures in the US population and provide further insight into the utility and safety of these procedures. A cost analysis will be performed, and it is hypothesized that the reusable components of the Storz MIP set will result in lower costs of the mini-PCNL procedure compared to standard PCNL.
Renal stones are one of the most common urological problems and there are multiple methods for their management such as percutaneous nephrolithotomy, mini and ultra-mini percutaneous nephrolithotomy, flexible ureteroscopy and laser lithotripsy, and extracorporeal shock wave lithotripsy. percutaneous nephrolithotomy is the treatment of choice for the management of renal calculi, in spite of the increasing stone clearance rate, the complication rate of this procedure is relatively higher.
This study aims to compare the narrow focus (F1) versus the wide focus (F3) in terms of the efficacy of Shock Wave Lithotripsy (SWL) in the management of renal calculi 1-2 cm and their injurious effect on the kidney.
This study is intended to be a prospective registry of patients undergoing any kind of stone treatment that have a pre-operative CT available. This imaging will be used to measure the stone burden in three different ways: in a single dimension (cumulative stone diameter), in two dimensions (surface area) and in three dimensions (volume).The primary purpose is to identify what way of measuring stone burden is most predictive of outcomes after stone treatment such as stone free status, operative time and complications.
