title: [Extracorporeal lithotripsy for urolithiasis: retrospective study of 227 patients].
abstract: Presentation of a retrospective study in 227 lithiasic patients with indication for extracorporeal lithotrity (ESWL) as first line of therapy or as adjuvant treatment, referred to three lithotripter units over the last five years. There was a high percentage of personal history of lithiasis (55.5%), colic pain being the most frequent symptom (78%). Lithiasis largely affected one single renal unit, most often the left one (54.7%) and was solitary in 54.6% of cases. Calyceal and pyelic sites were the most common ones, the size of the stones ranging between 10-19 mm in 44.5% of cases. Overall results reflect a 78.5% success rate, with statistically significant lower occurrence of residual fragments in the right renal unit. There was greater success rates in ureteral calculi followed by calyceal ones and also in the smaller ones compared to those greater than 20 mm. Double-J ureteral catheterism was performed in 27% patients, with evidence of statistical significance between them and those uninstrumented in relation to occurrence of lithiasic trail. An 11% rate of significant complications requiring endourological handling due to obstruction in 7.5%, and open surgery in 3.5% due to complication or lack of resolution was detected.
