Double collecting system with ectopic ureterocele masquerading as an ovarian torsion

Taiwan J Obstet Gynecol. 2018 Dec;57(6):867-870. doi: 10.1016/j.tjog.2018.10.018.

Abstract

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.

Keywords: Acute abdomen; Duplex system; Ureterocele.
