H. Ohlsen et Ac. Kinn, PERCUTANEOUS EXTRACTION OF UPPER URINARY CALCULI UNDER FLUOROSCOPIC CONTROL - STILL A VALUABLE COMPLEMENT TO ESWL, Scandinavian journal of urology and nephrology, 27(3), 1993, pp. 311-321
Percutaneous extraction of 372 renal and proximal ureteral calculi was
performed under fluoroscopic control in 202 consecutive patients. In
193 kidneys (90 %) removal of stones was performed under fluoroscopic
control only and in 10 % initial ultrasonic disintegration was used. A
completely stone free kidney was achieved in 74 %. If successful outc
ome is defined as no stones or residual fragments less than 5 mm, the
success rate was 91 %. With a mean size of 10.3 mm 259 intact stones w
ere extracted under fluoroscopic control. Open surgery was performed i
n 13 of 202 patients, in 10 of these cases due to unsuccessful removal
of an impacted ureteral stone. Complications occurred in 16 %, none o
f them were serious. Open intervention became necessary in 2 patients.
Bleeding which required blood transfusion occurred once. Percutaneous
renal stone extraction under fluoroscopy is safe and useful in select
ed patients when ESWL can be expected to produce less favourable resul
ts. The ability to perform this technique should therefore be well mai
ntained.
