Filter by:This research aims to study the effectiveness of silodosin in the management of lower ureter stones larger than 6 mm in diameter in terms of affected ureter (right or left), the size of the stone, the degree of hydronephrosis, the rate of stone expulsion(day), whether the stone was completely expelled or not, and the side effects of silodosin.
Rcompare high-energy versus low-energy laser settings in renal stone lithotripsy using low power machines) Holmium YAG 30 watts, examining their respective advantages, limitations, and overall efficacy.
This prospective randomized comparative study was done at Helwan University Hospital. It was conducted on 120 patients with unilateral pelvic renal stones from 1.5 to 3 cm in largest diameter who was admitted through duration to compare the two procedures differences in terms of complications, analgesic use, hospital stay, operational time, and stone-free rates.
There is a global increase in the prevalence of urolithiasis in children attributed to lifestyle changes, dietary habits, climate changes, childhood obesity, and the wider availability of ultrasonography. The rising incidence of the disease with its recurrent nature emphasizes the need for minimally invasive therapeutic options. Patients in whom RIRS has been performed in the last four years with increasing experience will be presented, and complications, stone-free rates, and technical details will be discussed. This retrospective Cohort study included children who underwent RIRS. Medical history, serum electrolytes, midstream urine culture, urinalysis, serum creatinine, complete blood count, and coagulation assessments were performed preoperatively. Ultrasonography (USG) was performed three months, 6 months, and 1 year after the procedures to evaluate stone recurrence and hydronephrosis. The investigators analyzed the stone-free rate ,complications, and the conversion to open procedure
The aim of this study is to evaluate the flexible ureteroscope (FURS) technique with and without ureteral access sheath (UAS).
The study has been conducted in Urology department at Kafrelsheikh University Hospital between March 2022 to March 2023. informed consent was taken from eligible patients and were randomized into three groups, Group A :Flexible ureteroscope (F-URS) group underwent holmium laser lithotripsy using flexible ureteroscopy (Boston® scientific (lithovue) while, Group B : extracorporeal shock wave lithotripsy (ESWL) group underwent electromagnetic extracorporeal shock wave lithotripsy (STORZ® MEDICAL Modulith SLX-F2 FD21, Germany) .Group C : Mini perc group underwent holmium laser lithotripsy using Karl® Storz MIP set.
The goal of this [ type of study:]prospective randomized clinical trial. The main question is to compare the outcomes of mini-percutaneous nephrolithotomy (m-PCNL) and retrograde intrarenal surgery (RIRS) in treating upper urinary tract calculus in children ≤ 10 years.
Percutaneous nephrolithotomy (PNL) is the gold standard recommended treatment technique for kidney stones larger than 20 mm. For kidney stones between 10 - 20 mm, both shock wave lithotripsy (SWL) or flexible ureterorenoscopy (f-URS) are recommended as the first choice of treatment and PNL is recommended as the second. In patients who are planned to undergo f-URS, a ureteral access sheath (UAS) is placed in the ureter at the beginning of the operation in order to provide a better image, reduce intra-renal pressure, easier stone fragment retrieval and shorter operative time. In certain cases, such as ureteral stricture, kink or edema, the ureteral access sheath may not be able to successfully inserted into the ureter. At this stage, double-J (JJ) stent can be inserted into the ureter to create passive dilatation, and a second f-URS session can be scheduled a few weeks later. Another option is to perform PNL operation to the patient in the same session. In this randomized prospective study, we aimed to compare these two different surgical approaches in terms of patient comfort and surgical success in patients with kidney stones between 10 - 20 mm in which access sheath insertion was failed in the initial f-URS session.
The aim of this study is to compare the effectiveness of Ultrasound-Guided Percutaneous nephrolithotomyin different positions supine, prone positions and flank suspend supine position in renal stones treatment.
The primary purpose of this study was to compare the effects of erector spinal plane block (ESP) and IV patient-controlled analgesia (PCA) performed to provide analgesia in percutaneous nephrolithotomy surgeries on visual analog skala (VAS), additional analgesia need, patient satisfaction and mobilization times.
