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.
Objective: To improve quality-of-life and health care delivery to patients receiving ureteral stents. Specific Aims: Evaluate the feasibility, practicality, and qualitative outcomes of utilizing intra-nasal ketorolac in patients with indwelling ureteral stents (Phase I), followed by a randomized trial comparing two non-steroidal anti-inflammatory drugs, intra-nasal Ketorolac versus oral Diclofenac. Hypotheses: Due to its favorable pharmacokinetics in relieving acute pain, investigators expect improved pain scores and a lower rate of unplanned clinical encounters in patients receiving intra-nasal ketorolac compared to those taking oral diclofenac following ureteroscopic surgery for urolithiasis. Study Rationale: Following ureteroscopic management of urolithiasis, patient with indwelling ureter stents have higher levels of discomfort compared to those without a ureter stent. Prior studies showed that intramuscular Ketorolac at time of ureter stent removal decreased the incidence of unplanned clinical encounters. Furthermore, onset of analgesic effect by intra-nasal ketorolac is faster than its oral form, and similar its intramuscular and intravenous counterparts.
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.
The study aims to compare renal oxygenation levels in retrograde intrarenal surgery (RIRS) and ureteroscopy (URS) procedures with a control group. Additionally, it seeks to determine if there is a connection between postoperative infection parameters and intraoperative renal oxygenation measurements.
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.
This study will be conducted to compare early (one week) versus delayed (2-4 weeks) definitive ureteroscopic lithotripsy after initial drainage for obstructing ureteral or renal stones associated with infection.
Background: Pregnancy is associated with a higher risk of common bile duct stones. Currently Endoscopic Retrograde Cholangiopancreatography (ERCP) is the treatment of choice for symptomatic choledocholithiasis. However, ERCP during pregnancy is associated with hazards of radiation exposure, as well as challenging patient positioning and anesthesia
