Background. Over the past 20 years, the management of ureteropelvic junction obstruction (UPJ) has shifted. While many urologists note a decrease in the number of pyeloplasties performed over time, the nature of the change in practice has yet to be defined. In the current study, we utilize a national, multi-institutional database of children's hospitals to evaluate trends in patients undergoing...

BACKGROUND AND OBJECTIVES We aimed to assess the feasibility and outcomes of complex ureteropelvic junction obstruction cases submitted to robotic-assisted laparoscopic pyeloplasty. METHODS The records of 131 consecutive patients who underwent robotic-assisted laparoscopic pyeloplasty were reviewed. Of this initial population of cases, 17 were considered complex, consisting of either atypical...

OBJECTIVE To compare ultrasound (US) scan and nuclear renography findings in patients who underwent pyeloplasty with and without pelvic reduction in a randomized prospective study. METHODS A total of 42 patients, all prenatally diagnosed with unilateral hydronephrosis, were included. Hydronephrosis was confirmed postnatally. Twenty patients were randomly selected to undergo pyeloplasty with p...
