In this study, we aimed to assess the significance of two urinary biomarkers; caspase 3 and TNF-a, in patients with UPJO
within six months of follow-up.
2) Although several cases of giant hydronephrosis secondary to UPJO
have been reported in the medical literature, (3-5) the volume of the hydronephrotic fluid in these cases rarely exceeded 10,000 cc.
Anderson-Hynes (AH) dismembered pyeloplasty was the preferred choice in all but one patient with UPJO
GAD imaging during diuretic renography is safe and effective, and provides valuable, additional diagnostic information in pediatric patients with hydronephrosis and possible UPJO
Indication: Robotic-assisted ureterocalicostomy (RAUC) is a potential option in patients with UPJO
and significant lower pole caliectasis, patients with failed pyeloplasty and a minimal pelvis, or patients with an exaggerated intrarenal pelvis.
Delayed intravenous urography (IVU) revealed probable left UPJO
and a dilated left pelvic system (Fig.
An examination of patient demographics revealed that these two groups are somewhat heterogeneous, with differences in age, presentation pattern and likely, duration of UPJO
METHODS: A retrospective and prospective study of 7 years from May 2006-April 2013 with review of clinical presentation, Ultrasound findings, renal isotope scan findings and microscopy of UPJO
segments of 52 patients under 14 yrs, who underwent reconstruction at our hospital, a tertiary care pediatric center were studied.
All pediatric patients with primary UPJO
and with dilated renal pelvis were included.
The hypothesis for this study is that despite nearly ubiquitous screening and excellent follow-up, a significant number of our patients presented with previously normal imaging and underwent surgery for a symptomatic UPJO
Robot-assisted Laparoscopic Dismembered Pyeloplasty for Ureteropelvic Junction Obstruction is a safe, efficacious, and viable option for either primary or secondary repair of UPJO
with reproducible outcomes, a high success rate, and a low incidence of complications (7).
