Diagnosing the combination of renal dysgenesis, Gartner's duct cyst and ipsilateral müllerian duct obstruction

We describe the differential points in the diagnosis of the combination of renal dysgenesis, Gartner's duct cyst and ipsilateral müllerian duct obstruction. Various imaging studies and urological procedures were performed. We report our experience in detecting these anomalies in 10 girls and review the literature.

Ten girls, 7 to 13 years old, with this combination of anomalies were identified in the last 10 years. Imaging studies as well as urological procedures were selectively performed, especially at puberty following menarche. Patients received long-term followup with ultrasound.

Cystic dilation of Gartner's duct protruded into the bladder and presented as a ureterocele in 5 patients and posterior to the bladder in 5. Surgical removal of a partial portion of a Gartner's duct cyst was performed in 5 patients for alleviation of urinary symptoms. Unilateral müllerian duct obstruction was demonstrated in all 10 patients. Excision of the vaginal septum was performed in 6 patients for relief of genital obstruction.

When cystic dilatation of the pelvis, especially a ureterocele-like cyst without ureteral dilatation, is found in girls with ipsilateral renal dysgenesis, the possibility of a Gartner's duct cyst should be considered. For early detection and treatment of unilateral obstruction of duplicated müllerian ducts pelvic sonography should be performed at puberty, especially just after menarche, in girls with renal dysgenesis and ipsilateral Gartner's duct cyst.
