Outcome Measures
Primary Outcomes (1)
Stone free rate of Urereroscopy in fresh versus recurrent cases of stone ureter
• Stone free rate with a mean operative time of 1 hr by MSCTKUB or Plain KUB to determine residual stones post operative
1 day post operative by MSCTKUB or Plain KUB to determine residual stones post operative
Secondary Outcomes (3)
• Rate of intraoperative findings in each group.
Intraoperative
• The rate of complication in each group
Intraoperative by ureteroscope and one day post operative by MSCT
• The rate of stone impaction in each group
Intraoperative by ureteroscope
Study Arms (2)
Fresh cases
Outcome of URS in fresh stone ureter
Recurrent cases
Outcome of URS in recurrent cases of stone ureter post ESWL ,URS , open surgery
Interventions
URS is done to each group to reveal outcome of stone free rate in fresh versus recurrent cases of stone ureter
Eligibility Criteria
.4. 2- Study subjects: 1. Inclusion criteria: * all cases with middle and lower ureteric stone candidate for endoscopy. * Stone 15mm or less. 2. Exclusion criteria: * Patients with a ureteral stent. * Patient refusing participation. * Pregnant woman. * Active urinary tract infection. * Comorbidities prevent intervention including bleeding tendency or uncorrectable coagulation profile. 3. Sample Size Calculation: Based on previously reported frequency of primary failure of ureteocopy in case of recurrent stone that ranged between 1-37% (\*reference)\* a total sample size of 62 patients will be required ( 31 patients in each arm) with the following assumption; alpha error 5%, 80% power with 95% confidence interval
You may qualify if:
- all cases with middle and lower ureteric stone candidate for endoscopy.
- Stone 15mm or less.
You may not qualify if:
- Patients with a ureteral stent.
- Patient refusing participation.
- Pregnant woman.
- Active urinary tract infection.
- Comorbidities prevent intervention including bleeding tendency or uncorrectable coagulation profile.
