Pyéloplastie laparoscopique

Ureteropelvic junction (UPJ) obstruction in adults is usually symptomatic, secondary, and it tends to progress. Surgical correction of obstructed UPJ is necessary to preserve the renal function of the affected kidney. Pyeloplasty as a surgical management for UPJ obstruction in adults has proven its efficacy with high success rates on long-term results. Laparoscopic pyeloplasty in the management of primary or secondary UPJ obstruction in adults technically duplicate the open surgical technique. Laparoscopic pyeloplasty has developed to match success, morbidity and complication rates of open surgical pyeloplasty. However it was shown that laparoscopy had consistently a shorter convalescence than open surgery. Endopyelotomy is utilized to manage UPJ obstruction. Early results for endopyelotomy were promising but long-term results were not encouraging. In the management of UPJ obstruction in adults, long-term success rates for laparoscopic pyeloplasty were found to be superior to those of endopyelotomy. Therefore we believe that laparoscopic pyeloplasty will become as a standard management for UPJ obstruction in adults.
