To Compare the Effectiveness of Transurethral Pneumatic Lithotripsy and Extracorporeal Shock Wave Lithotripsy: In treatment of Lower Ureteric Stones

Abstract

Background: One of the most common complaint in the ER is colic due to Ureteric calculi. They usually pass out but stones > 5mm
may require intervention. ESWL and TPL are one of the treatment options.
Objectives: To compare the effectiveness of transurethral pneumatic lithotripsy (TPL) and extracorporeal shock wave
lithotripsy(ESWL) in treatment of lower ureteric stones.
Material and Methods: Over period of six months a group of 70 patients presenting with ureteric calculi were randomly allocated in
two groups. Group Aunderwent TPL while Group B ESWL. Follow up was done to determine the effectiveness with regards to stone
clearance.
Results: The mean age of the whole study sample was 35.6 + 8.5 years. The difference between mean age of both groups was
statistically not significant (p 0.665). there were 70% males compared to 30% females in the overall sample and the difference of
gender across both groups was comparable (p 0.192). The mean size of stone of the whole study sample at presentation was 6.4 +
2.5mm and the duration of illness was 4.8 + 1.8months. On follow up, the effectiveness of the procedure in terms of stone clearance
was recorded in 88.6% of TPL group and 77.1% of ESWL group (p 0.205).
Conclusion: TPL is comparable to the ESWL in terms of its effectiveness for ureteric calculi of size less than or equal to 10mm.
More research trials need to be done for conclusive outcome.
