upjo

(ŭp′jō″)
A commonly used acronym for ureteropelvic junction obstruction. The ureteropelvic junction is the last segment of the ureter, through which urine normally passes into the bladder. It is a common location for kidney stones to lodge and obstruct the flow of urine when they pass from the renal pelvis down the ureter.

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.
Conclusions: Laparoscopic pyeloplasty is becoming the treatment choice for UPJO, but intracorporeal laparoscopic suturing and tissue handling remain a challenge to nonexperienced laparoscopic surgeons.
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.
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.
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).
