PREDICTIVE FACTORS OF POST EXTRACORPOREAL SHOCK WAVE LITHOTRIPSI COMPLICATION EVENTS
Abstract: To know if
pre-morbid factors such as maximum power, maximum frequency, repeated extracorporeal
shock wave lithotripsy (ESWL), age, hypertension, diabetic, nutrition, blood
coagulation disorders, kidney function disorders, pain perception, stone
burden, and stone location, can be use to predict ESWL complication. Material
& methods: This study is done retrospectively. Analysis was done on 50
patients undergoing ESWL between July 2014 to December 2015. Free variables
which evaluated were maximum power, maximum frequency, repeated ESWL, age,
hypertension, diabetic, nutrition, blood coagulation disorders, kidney function
disorders, pain perception, stone burden, and stone location. Dependent
variable which evaluated was steinstrasse event, post ESWL fever, post-ESWL
renal colic, post-ESWL hematuria. Age variable were distributed normally and done
bivariate analysis by student T-test. Others were abnormally distributed and
analyzed univariately by Mann U Whitney. Results: During study period, 50
patients were collected. Among them, 60% were men and 40% were women. Mean age
of patients undergo ESWL were 50.9 +12.7 years. Mean stone size that undergo
ESWL were 172.7 + 277.8 mm2. Patients with hypertension before ESWL were 9
patients. Stones were mostly located on kidney pyelum (29 patients), inferior
calix (11 patients), superior calix (5 patients), middle calix (4 patients),
and 1 patients has staghorn stone. After ESWL, none of the patients complaining
severe pain, 35 patient complaining mild pain, and 15 patient complaining
moderate pain. Repeated ESWL done in 16 patients (32%). Post-ESWL complication
such as hematuria happened on 12 patients, steinstrasse on 1 patient, and colic
on 6 patients. None of patients complaining fever. Repeated ESWL happened on
32% patients and have complication risk of hematuria (p=0.043). Hypertension is
significantly effecting on hematuria event after ESWL (p=0.015). Conclusion:
Hypertension and repeated ESWL can be used as predicting factor of hematuria
complication.
