Mini- Percutaneous Nephrolithotomy Versus Extracorporeal Shock Wave Lithotripsy for High Density Renal Stones
Egypt72 participantsStarted 2020-07-14
Plain-language summary
Several studies were conducted to compare extracorporeal shockwave lithotripsy (SWL) and percutaneous nephrolithotomy (PNL) as treatment options for medium size lower caliceal high dense stones. However, no studies compared these options for non- lower polar stones.
In the present study the investigators will compare mini-PNL and SWL in treatment of non- lower polar, medium size, high dense renal stones in reference to the stone free rate and safety of the procedures.
Pre-operative evaluation including abdominal non-contrasted computed tomography will be performed for all patients. Patients will be randomly allocated into two equal groups and will be treated by either mini-PNL or SWL. postoperative, patients will be followed by regularly for 3 months. the outcome of the procedures will be evaluated and compared between groups.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult patients with high density (\>1000 HU), non-lower polar, single renal stone of 10 to 20 mm size
Exclusion Criteria:
* Pregnant women, morbid obesity, severe orthopaedic deformities, any co-morbidities precluding general anaesthesia or prone positioning, uncorrectable coagulation disorders, active urinary tract infection (UTI), stone in calyceal diverticulum, abnormal renal anatomy and urinary tract obstruction distal to the stone
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
