ALMEIDA, Gilberto L. et al. Prospective trial comparing laparoscopy and open surgery for management of impacted ureteral stones. Actas Urol Esp [online]. 2009, vol.33, n.10, pp.1108-1114. ISSN 0210-4806.

Introduction and objectives: To investigate two ureterolithotomy approaches for treatment of large and impacted upper ureteral stones, we prospectively evaluated the perioperative features of consecutive patients submitted to ureterolithotomy following failure of endourological treatment. Methods: Of the 110 patients included in the study, 34 underwent laparoscopic ureterolithotomy. Patients were divided into three ureterolithotomy subgroups (group A, 76 open procedures; group B, 16 transperitoneoscopies and group C, 19 retroperitoneoscopies). All procedures were performed into a urology residency program. Results: The patients’ age, sex, ASA classification and stones characteristics showed no significant difference between the groups. Overall, complication rates and the operation times recorded were similar. One patient had bilateral stones and both sides were managed in a single transperitoneoscopy procedure. Three retroperitoneoscopies were converted to an open surgery due technical difficulties. A prolonged urinary leakage occurred in 3/35 cases (8.5%) where 2 patients were treated by placing a ureteral catheter. Both laparoscopic groups have significantly less analgesia requirements and shorter hospitalization (p < 0.001 and p = 0.003, respectively). All patients were stone-free in the follow-up 1-month visit. Conclusions: To our knowledge, my in a laparoscopic training scenario. Even though these procedures were performed by limited laparoscopic experience urologists, laparoscopy offered significant advantages over traditional open ureterolithotomy, resulting in improved analgesia, shorter hospital stays and similar complication rates.
