Filter by: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.
With advances in endourological equipment, minimally invasive procedures have been found to be sufficient for the treatment of ureteral stones in children. The investigators aimed to evaluate the stone-free rate and complications related to the procedure and to compare it with the period when their experience were limited by presenting their patients with ureteral stones treated by ureteroscopy (URS) and holmium YAG laser in the last three years after their 15-year routine endourological practice. The investigators retrospectively compared 54 cases treated with ureteroscopy (URS) for ureteral stones between 2009-2011, the first three years of our endourological interventions in children, and 78 cases treated with URS for ureteral stones between 2020-2022, the last three years of their 15-year endourological experience, from hospital records. Demographic data, stone-free rates, number of procedures and recorded complications were evaluated in both groups.
This study was designed to find our whether a novel toothpaste containing safe digestive enzymes (Tartarase) was able to remove pre-existing dental tartar when compared to a well-known toothpaste (Crest). A group of 40 test subjects that had at lease 9 mm of tartar on the tongue side of the 6 lower front teeth, were randomly divided into 3 groups unknown to the the team overseeing the measurements. All the groups brushed with a toothbrush approved by the American Dental Association. Group A (20 subject) was the control group. They brushed in the morning and before bed with Crest for 2 minutes. Group B (10 subjects) brushed in the morning and before bed using the same procedure, first with Tartarase for 30 seconds, spit, but did not rinse, then repeated. After 30 minutes then brushed with Crest. Group C (10 subjects) brushed for 30 seconds with Tartarase, spit but did not rinse, then filled a dental tray with Tartarase and covered the 6 lower front teeth and waited 30 minutes, spit but did not rinse and brushed for ann additional 30 seconds with Tartarase. After 30 minutes they brushed with Crest. They brushed with crest before bed, without another Tartarase treatment. The study was a 4-week study, with tartar measured at the start (baseline), again after 2 weeks and again at the final study point of 4 weeks. If any of the study subjects experienced anything unpleasant, they were to inform the team overseeing the study. The tartar measurements were compiled into the 3 groups and statistically analyzed to determine if there were any changes in the amount of tartar within the groups and between the groups.
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 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.
Objective: To observe the effect of Ningmitai capsule on ureteral calculi after lithotripsy and evaluate the safety of treatment. Study Design: A multicenter, prospective, randomized, controlled clinical study design was adopted Interventions: control group: Give antibiotics or diclofenac sodium suppository as needed. Ningmitai group: Oral Ningmitai Capsule (produced by Guiyang Xintian Pharmaceutical Co., Ltd.), 0.38 g/capsule, 4 capsules each time, 3 times a day. combination group (Ningmitai plus tamsulosin).: Tamsulosin capsules, 0.2 mg/capsule, one capsule each time, once a day, were taken on the basis of Ningmitai group.
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.
Around 10-18% of patients undergoing cholecystectomy for gallstones have common bile duct (CBD) stones. Currently, various procedures for the treatment of cholecystocholedocholithiasis are available including open cholecystectomy plus open common bile duct exploration (OC+OCBDE), laparoscopic cholecystectomy plus laparoscopic common bile duct exploration (LC+LCBDE), may be trans-cystic or trans-choledochal, and laparoscopic cholecystectomy plus endoscopic retrograde cholangiopancreatography (LC+ERCP), which may be performed pre, at, or after LC.
The goal of this observational study is to analyse the occurence of urinary calculi after bladder augmentation in children: - location of the calculi (kidney or bladder) - type of bladder augmentation with higher rate of urinary calculi and why - Find risk factors of urinary calculi in bladder augmentation (age, sex, other bladder procedures..)
