Renal abnormalities in Mayer-Rokitanski-Küster-Hauser syndrome.

ABSTRACT

Mayer-Rokitanski-Kuster-Hauser (MRKH) syndrome, is a rare disorder characterized by the congenital absence of the uterus and vagina. The prevalence has been reported as one in 4000-5000 female births. Patients with MRKH syndrome have a 46.XX karyotype and normal secondary sex characteristics. The external genitalia appear normal, but only a shallow vaginal pouch is present. Ovarian function is normal. A 54-year-old woman came to our observation for the treatment of arterial hypertension. Her history involved primary amenorrhea and sterility. She had undergone abdominal and pelvic sonography as a routine screening and they had shown the absence of the uterus, left renal agenesis and a contralateral pelvic kidney. These findings were confirmed by urography and CT scan of the abdomen. Gynecologic examination showed a small vaginal pouch (2 cm). Thus, the diagnosis of MRKH syndrome with associated congenital anomalies of the upper urinary tract was made for the first time in this lady at the age of 54 years. Associated congenital anomalies of the upper urinary tract are reported to occur in 30-40% of all cases of MRKH syndrome. No specific figures are available on what percentage of women with missing kidney might also have MRKH syndrome. However, in 40-50% of patients with renal agenesis, an associated genital anomaly has been found. In conclusion, this report is intended to remind our community of the existence of congenital renal abnormalities associated with gynecologic abnormalities, a field of nephrology usually amply neglected.
