Objective: To investigate the treatment effect of pyeloplasty in the treatment of ureteropelvic junction obstruction. Methods: A retrospective review of 25 cases of ureteropelvic junction obstruction diagnosed and treated by the authors from 1987 to 1999 was performed. Among them, 19 patients underwent segmental pyeloplasty and 6 underwent nephrectomy. Results: 19 cases of pelvis formation were successful. Conclusion: The broken pyeloplasty design is reasonable and the success rate is high. It should be used as the first choice for ureteropelvic junction obstruction.
