About this trial

This is an interventional treatment trial for Ureteric Stone focused on measuring ureteric stone, SWL, High density stones, Ultraslow SWL, Slow SWL, Ramping, Pause

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • single upper ureteric stone less than or equal to 2 cm
  • radio-opaque stone
  • high attenuation value (≥ 1000 HU) stone

Exclusion Criteria:

  • Abnormal renal anatomy
  • renal insufficiency
  • solitary kidney
  • coagulopathies
  • uncontrolled hypertension
  • renal artery or aortic aneurysm
  • active urinary tract infection
  • pregnancy
  • severe skeletal malformations (spinal deformity) precluding proper stone localization

Sites / Locations

  • Beni-Suef Hospitals

Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

Active Comparator

Arm Label

Ultraslow shock wave lithotripsy (SWL)

Slow power-ramping SWL

Arm Description

SWL at ultraslow rate of 30 SW/min. Power ramping at the first 100 SW from 6 to 18 kv followed by safety pause for two minutes then power ramping from 18 to 22kv during the second 100 SW followed by safety pause for another two minutes. The rest of the session at 22kv (full power).

SWL at a slow rate of 60 SW/min. Power ramping from 6 - 10 kv during the first 500 SW then from 11 - 14 kv during the second 500 SW then from 15 - 18 kv during the following 500 SW then from 19 - 22 kv during the remaining 1000 - 1500 SW.

Outcomes

Primary Outcome Measures

stone free rate
Complete clearance of stones in addition to clinically insignificant residual fragments

Secondary Outcome Measures

Complications rate
Comparison of rate of complications in both groups
