MATERIAL AND METHODS The prenatal ultrasound detected a phallic structure, megacystis, hyperechogenic small kidneys and oligo/anhydramnion. Intra-amniotic infusion were necessary to save the fetus, born at 34-weeks with pulmonary hypertension, distension of the lower abdomen, and DSD with a pseudophallus of 4.5 cm. The anus appeared in ante-position but with normal caliber. There were a urogenital sinus deviated posteriorly opened in anus and an accessory, phallic urethra. Spontaneous urination did not occur and urethral- and sinus catheterization failed. We performed a vesicostomy. RESULTS Investigations showed a nonfunctional left kidney, a small echogenic right kidney with an ectopic implantation of his refluxive ureter on the dome of the bladder. Both, the phallic urethra and the urogenital sinus were stenotic and connected to a three-compartment urinary bladder. Other associ- ated pathologies included left hemiuterus, and vaginal atresia. CAH and hnf1ß- wt-mutations where genetically excluded, but by NGS a LHX1 mutation was identi- fied, which could be associated with the above findings but hasn't been described before. The level of creatinine was 3.8 mg/dl in the 5-th day of live: peritoneal dialysis was performed for 3 weeks, thereafter the patient remains symptoms free against ESRD: CKD 5, estimated GFR- cystatin-C 15 mL/min/1,73 m2. With 19 month we accomplished the bladder neck closure with continent urinary diversion and feminizing genitoplasty. CONCLUSIONS Transplantation of a living-donor kidney at 52-month of age was successful. The transplanted kidney has a normal function and the patient is with CIC socially continent.
