Tratamento cirúrgico da litíase vesical: Revisão de literature

Abstract

Bladder stones are rare and in most cases occur in adult men with bladder outlet obstruction. Currently, there are few data on the best treatment of this disease. The aim of this review is to discuss some aspects of pathogenesis and treatment approaches for bladder lithiasis. A comprehensive search of the database of the "National Library of Medicine"/pubmed was conducted with the following key words and descriptors: "bladder" or "vesical" associated with "calculus", "stone" or "lithiasis", and "cystolithotripsy". One hundred and seventy-one articles were identified. The articles were independently assessed by two reviewers with expertise in urolithiasis. They were included in the study when the results, complications and follow-up were clearly reported. In the end, 32 studies met the inclusion criteria. Several options for the treatment of bladder lithiasis are available, but no randomized trials comparing them. Different rates of calculus-free patients are described in each of them, as follows: extracorporeal shock wave lithotripsy (75-100%), transurethral cystolithotripsy (63-100%), percutaneous cystolithotripsy (89-100%) and open surgery (100%). The percutaneous approach has lower morbidity, with similar results to the transurethral treatment, while extracorporeal lithotripsy has the lowest rate of elimination of calculi and is reserved for patients at high surgical risk.
