DIFFERENT?

PURPOSE
Pyeloplasty has historically been performed in patients after the first year of life. The purpose of this
study was to compare outcomes between patients above and below one year of age undergoing
robotic-assisted laparoscopic pyeloplasty (RALP).
MATERIAL AND METHODS
We performed a retrospective review of patients aged < 18 years undergoing primary RALP for
ureteropelvic junction obstruction (UPJO). We evaluated operating room parameters and complica-
tion rates between infant (age < 1 year) and non-infant (age ≥ 1 year) patients, and then assessed
radiographic outcomes by comparing change in SFU grade of hydronephrosis between the two age
groups.
RESULTS
One hundred consecutive primary pyeloplasties met inclusion criteria, including 28 infant cases.
The first infant operation was performed only after achieving surgeon’s confidence in non-infants
(n=27). The infant group had shorter median operating room time (142 versus 178 minutes, respec-
tively; p=0.001) than the non-infant group. The rate of high-grade complications (Clavien ≥3) was
low overall, and similar in both groups (7.1% in infants versus 13.9% in non-infants; p=0.546); these
included four patients who required repeat pyeloplasty. Rates of stable or improved hydronephrosis
(96.4% versus 94.4%, p=0.683) and degree of improvement (-1.0 vs. -1.3, p=0.219) were favorable
in both groups.
CONCLUSIONS
RALP is an excellent option for both infant and non-infant pediatric patients with UPJO. In the hands
of an experienced surgeon and skilled operative team, radiographic outcomes and complication
rates are favorable and similar in infants when compared to non-infants.

PURPOSE
Although open pyeloplasty remains the standard for treatment of UPJ obstruction, robotic pyelo-
plasty (RP) has gained popularity, and is now the technique of choice in some centers. It has been
reported that confidence and experience with robotic techniques increase considerably after the first
30 cases. We compared the outcomes of our first 30 RP cases against later cases.
