OBJECTIVE: The opinion on the use of retrograde ureteropyelography (RUPG) prior to routine pyeloplasty for an ureteropelvic (UPJ) obstruction has been divided.
This study analyses the efficacy of a preoperative RUPG and determines if a dorsal lumbotomy (DL) approach offers any advantage in this situation.
METHODS: This is a retrospective analysis of application of RUPG prior to pyeloplasty in children with ages ranging from 42 days to 16.2 years who underwent surgery at the Children's Hospital at Westmead between 2009 and 2013.
RESULTS: We identified a total of 95 children with isolated UPJ obstruction, with 59 (62.1%) boys and 36 (37.8%) girls. Overall, open pyeloplasties were performed in 89 (42 DL: 47 loin incision) and the rest (n = 6) laparoscopically. Preoperative RUPG was performed in 58 (61%) and it provided additional information in 11 (18.9%) patients for whom the surgical approach was modified. Hospital stay, operative time, and time to full diet were shorter with the DL approach (p < 0.05).
CONCLUSIONS: The current study suggests that RUPG is avoidable if the approach for pyeloplasty is through the conventional loin incision. The short-term advantages might rationalize the use of RUPG if a DL incision is employed.
