Laparoscopic Transperitoneal Pyeloplasty Outcomes in Adult Patients with Ureteropelvic Junction Obstruction

Abstract

Background: Ureteropelvic junction obstruction (UPJO) is a frequently observed abnormality in the ureters of children. It has been reported that UPJO is approximately 5 cases per 100,000 infants each year. The obstruction at the ureteropelvic junction can be attributed to factors originating within the ureter itself (intrinsic UPJO). In contrast, cases caused by external factors are uncommon and usually result from abnormal vessels crossing the area crossing aberrant vessels.
