01), approaching the level measured in children without UPJO
after six months.
is the most common etiology for congenital hydronephrosis.
Sixty percent of robotic patients had a crossing vessel at the UPJO
Patients with missing or incomplete data were excluded and so were those having secondary UPJO
flank pain or pyelonephritis) related to their UPJO
In literature, UPJO
was the most common cause of giant hydronephrosis 33% (as in our case), followed by stones 20% and congenital ureteral narrowing.
21) Additionally, robot-assisted laparoscopic "reoperative" pyeloplasty in children with persistent UPJO
after open surgical correction is also reported to be a safe and effective option in the treatment of these challenging cases.
2) The coexistence of trifid pelvis and UPJO
In contrast, patients who had a DJ stenttended to be older, with a mean age of 80 [+ or -] 78 months and presented with antenatal hydronephrosis and symptomatic UPJO
in 45% (n = 17) and 32% (n = 12), respectively.
may be considered, in most cases, as a functional obstructive condition due to maturative abnormalities, during the gestation, in the smooth muscle and/or the innervation of the pyelo-ureteral transitional segment, defective peristaltic waves and resulting in aperistaltic segment and difficulty to eject urine from the renal pelvis into the ureter.
3-5) In this study, we described our technique and reported our results in 25 pediatric patients who underwent a laparoscopic dismembered pyeloplasty (LDP) for UPJO
Classically, patients present with Dietl's crisis, infections, or kidney stones; however, prenatal assessments aim to identify significant UPJO
and prevent deleterious consequences.
