Objective:
Ureterocele in a duplex system is rare and commonly presented with urinary tract infection at neonatal age, infant or childhood. Symptomatic ureterocele in reproductive-age is a diagnostic challenge and should be highly awarded to avoid miss-diagnosis.
Case Report:
An adolescent girl with right ectopic ureterocele presented as acute abdomen that mimicked ovarian torsion received emergent laparoscopic surgery. Right ureterocele was identified and excised. Computed tomography later showed bilateral renal duplications with visible renal parenchyma and upper ureters. Recurrent abdominal pain with pelvic abscess occurred 10 days after surgery. Laparoscopic right partial nephrectomy of the upper moiety and resection of the residual ureterocele was performed. Cystoscopy showed absence of intravesical ureterocele and her symptoms were completely resolved after surgery.
Conclusion:
Infected ureterocele in a duplex system is a rare condition and should be kept in mind as differential diagnosis.

Torsional Pendulum
As long as the rigid body's angular displacement is small, its oscillation can be modeled as a linear angular oscillation. The amplitude of the oscillation is an angle. The role of mass is played...
Bending and Torsional Moments
The reaction developed in a structural element when subjected to an external force causes the element to bend. When a structural element bends upwards, it creates compressive normal forces on the top and tensile normal forces on the bottom, resulting in a couple that determines the bending...
