Abstract:
This study was conducted to determine the role of Ultrasound in evaluating of
renal stone in patients treated with lithotripsy, by assess the accuracy with which
renal stones before ESWL, and the changes in the calculi after( ESWL) and evaluate
the possibility of renal scan to detect the Complications of this procedure.
The place of this work was lithotripsy Unit of Military Hospital (Omdurman). The
duration of study was 6 months from first October 2011 to April 2012,43 patients with
renal calculus included in study for ultrasound scan, criteria have been identified.
Extracorporeal Shock Wave Lithotripsy(ESWL) application has been intuitively
connected to complications.
These are related mostly to residual stone fragments, infections,
and effects on tissues such as urinary, gastrointestinal, cardiovascular,
genital, and reproductive systems. Recognition of ESWL limitations, use
of alternative therapies, correction of pre-existing renal or systemic
disease, treatment of urinary tract infection, use of prophylactic antibiotics,
and improvement of ESWL efficacy are the most important
measures of prevention. Decrease of shock wave number, rate and
energy, use of two shock-wave tubes simultaneously, and delivery of
two shock waves at carefully timed close intervals improve ESWL efficacy
and safety.
Conclusion: ESWL is a safe method to treat stones when proper indications
are followed.
This study demonstrates that, use of sonography before ESWL in patients with
nonopaque calculi may be helpful in detecting additional, unsuspected stones.
Furthermore, the variable sonographic findings after ESWL as compared with findings
of renal tomography indicate that the latter is more useful in evaluating the
effectiveness of shock-wave therapy.
