Introduction. Penile agenesis (aphallia) is an extremely rare congenital disorder. At present, about 100 cases of the anomaly have been described around the world. The incidence of this congenital anomaly is estimated to be one case per 2030 million births. One of the most commonly used reconstructive procedures today is the technique proposed by Roberto De Castro in 2007. In this article, we present a clinical case of aphallia in a boy who underwent phalloplasty. Materials and methods. A newborn boy presented with aphallia, combined with abnormal development of both kidneys. At birth, the child had difficult urination through the fistula at the edge of the anus. The meatotomy and urethral dilation were performed on the fifth day of the infant`s life. On day 28 of the child`s life, surgical intervention was performed to remove the left non-functioning kidney and a right cutaneous ureterostomy because of the recurrence of febrile urinary tract infection. At 13 months, the tissue expander was installed above the pubic bone. At 16 months, the child underwent the De Castro phalloplasty technique while in the supine position. Results. The child was examined 3, 6, and 12 months after the surgical treatment. Phalloplasty has had good outcomes as evaluated by parents and surgeons. At present, the boy is under the supervision of urologists, who plan to perform further surgical treatment of the urinary system. Conclusion. Phalloplasty, in the case presented, had a good cosmetic result. In our opinion, it proved to be the correct initial stage of treatment for aphallia, an extremely rare genital malformation.

Objective. The aim of this study is to evaluate the efficiency of transurethral incision of ureteroceles and incidence of vesicoureteral reflux in pediatric patients with duplex system ureterocele. Materials and methods. This is a retrospective study of 155 pediatric patients with duplex system ureterocele. The age of patients at the time of surgery ranged from 5 days to 17 years (median 8.0 months). Intravesical ureterocele had 108 patients (69.8%), extravesical 47 (30.2%). Results. Complications occurred in 2 patients (1.3%), recurrence obstruction was in 1 case (0.6%). Ipsilateral vesicoureteral reflux after surgery had 112 patients (72.3%): in the upper pole 51 cases (32.9%), in the lower pole 32 (20.6%), in both ureters 29 (18.7%). In the long-term period after transurethral incision of ureteroceles 97 patients (62.5%) needed reoperation due to infection and voiding dysfunction. Statistically significant risk factors associated with the need for reoperation were the presence of vesicoureteral reflux on the ureteroceles side and non-functioning upper pole of the kidney. Conclusion. Transurethral incision of ureteroceles for duplex system ureterocele is a safe and effective minimally invasive method of primary resolving of the obstruction. Vesicoureteral reflux on the ureterocele side after surgery had 72.3% of patients; reoperation in the long term was necessary in 62.5% cases. The main risk factor reoperation is vesicoureteral reflux on the ureterocele side.
