Series of clinical cases demonstrates functional state of lower urinary tract in girls with disorders of sex development (DSD) and hypospadias after the first stage of feminization. The study included 27 girls and women with DSD with hypospadias. Most of them have congenital adrenal hyperplasia (24), fewer girls have partial gonadal dysgenesis (1) and idiopathic virilization (2). Patients were examined before second stage surgical feminization in 115 years after the first stage. Concomitant pathology of the urogenital tract was detected in 19 (70%) patients. Urinary tract infection (UTI) was verified in 13 (48%), bladder dysfunction (BD) was diagnosed in 7 (26%), trapped menstrual secretions presented as hematometra, hematocolpos, and urine accumulation and stagnation in the vagina in anamnesis or as a result of preoperative studies were diagnosed in 9 (33%). Combination of the listed complications were observed in five patients (14%). Results of second stage of feminization confirmed connection of hypospadias with listed complications. This were detected in 11 (69%) patients after introitoplasty without separation of urinary and genital tracts (UGT). Introitoplasty with separation of UGT and elimination of hypospadias was complicated only four patients (36%), herewith the UTI and BD were eliminated. Hypospadias in girls with DSD is risk of development such complication as urinary tract infection, trapped menstrual secretions and bladder dysfunction. This circumstance requires change in surgical feminization tactics in girls with DSD, taking into account the anatomical components of genitalia malformations.

The choice of tactics for feminizing plastic surgery (one- or two-stage) remains an actually issue. To operate early, in the first months of a child’s life, when endocrinological stabilization is achieved, or to postpone the intervention until puberty? Despite the large number of approaches to surgical treatment, still not all results can be recognized as positive. There are complications that affect the quality of life of patients, not only of a surgical but also of a psychological nature. The advantages of one or another approach are currently impossible to prove, since this will require a prospective multicenter multidisciplinary study of long-term results with each of the approaches. Therefore, pediatric surgeons for a long time in the choice of tactics will be based on accumulated experience and logical reasoning. Given the extensive experience of multidisciplinary rehabilitation, the positive long-term results of two-stage feminization remains the preferred tactic for surgical treatment of girls with CAH. The increased risk of complications from the genitourinary system in the form of infections of the urinary tract, hematocolpos and hematometra in girls with a narrow common urogenital canal, which is inherent in virilization of 3, 4 and 5 degrees according to Prader, can be considered as a reason for an early one-stage feminizing plasty.
