Abstract:
Androgen insensitivity syndrome (AIS) is a very uncommon genetic disorder that results from the resistance of androgen receptor (AR) to androgen, which influences the formation of the male genitalia and in turn presents with female phenotype.Surgical resection of undesceaded testicle and different kinds of genitoplasty are crucial methods to correct the deformity of reproductive system, as well as hormone replacement therapy, which is an essential therapy for postoperational rehabilitation in AIS patients.A 43-year-old patient, who was socially female, was first admitted to gastroenterology department due to recurrent ascites and occasional abdominal pain with unknown origin.Taking physical examination, ultrasonography, karyotype analysis and sex hormone levels into consideration, the overall manifestations revealed the typical clinical features of complete androgen insensitivity syndrome.After that she was transferred to urology department for laparoscopic gonadectomy.During the surgery, doctors found that there was a vesical fistula on the upper wall near the conjunction between the bladder and ligamenta umbilicale medium, which explained the recurrent ascites for more than 4 years.After resecting the testicles and the tissues around the vesical fistula for histopathology, the result suggested Sertoli cell adenoma, hyperplastic Leydig cells and urothelium atypical hyperplasia.Hormone replacement therapy was given right after discharge.The hormone levels of follicle-stimulating hormone, luteinizing hormone, estradiol and progesterone were modulated by the dysfunction of androgen production after gonadectomy and hormone replacement therapy together with psychotherapy could stabilize her hormone levels and improve the quality of her life.The patient was suspicious of AIS family history and the pedigree was made to analyze her family which was possibly X-linked recessive pattern.We propose three possible hypotheses of the fistula, which are direct surgical injury, recurrence of bladder cancer and congenital urachal anomalies.But whether it is relevant between urachal anomalies and AIS is yet to be discovered.
