kidney staghorn calculi treatment ESWL

summary

Introduction. The treatment of the kidney staghorn calculi excent of new
surgical technics, remains controversial ESWL with addition of double J stent
is one these technics.
Objective, material and methods. The influence on results of ESWL
treatment of: stone size, recurrent nature of calculi, stone composition, dilatation
of upper urinary tract and stone location in the pelvico-calyceal system have
been estimated.
From 1988 to 1991 58 patients with partial and complete staghorn calculi
were treated by Wolf Piezolith 2300 lithotriptor at Yorkshire Lithotriptor Center
in Leeds.
Results. Stone free rate in the group with recurrent staghorn calculi was
57,9% and with primary calculi 85,4% and in the group with dilatated upper
urinar tract was 62,5% and non-dilatated group 86,1%. Urinary tract infection
decreased stone free rate, in the group with infection stone free rate was 74,5%
and in the group with no infection 88,9%. The most fre±uent localization of
the remnant stones was the lower pole of the kidney.
Conclusions. Dilatation of the pelvico-calyceal system, recurrent nature of
calculi, infection of urinary tract, stone location in calyces were bad prognostic
factors.
