RESUMO
PURPOSE: To present our experience with synchronous or metachronous laparoscopic pyelolithotomy and ureterolithotomy for patients with bilateral urolithiasis. MATERIALS AND METHODS: The data of all patients who underwent laparoscopic pyelolithotomy (± ureterolithotomy) for bilateral renal and/or ureteral stones from November 2009 to July 2014 were included. Laparoscopic operations were performed through a transperitoneal approach. RESULTS: 10 patients underwent laparoscopic operations for renal stones (19 kidney stones) and ureteral stones (1 ureteral stone). 4 patients underwent synchronous operations and 6 patients underwent metachronous operations. The mean ± SD of operation duration were 212 ± 51 minutes for synchronous operations and 166 ± 41 minutes for metachronous operations. Residual stone was observed 5 patients. No patient developed urinary leakage. CONCLUSION: Laparoscopic pyelolithotomy and/or ureterolithotomy for bilateral stones is a feasible option in centers with experience in laparoscopy.
