Introduction. Congenital pathology of internal genital organs (CPIGO) in children is rare. Underdevelopment or absence of the prostate gland may be accompanied by an anomaly of the seminal tubercle, seminal vesicle, testicles. Clinically, CPIGO in children is accompanied by dysuria, abdominal pain, lumbar regions, changes in urine tests, high fever. Often, CPIGO defects are found at autopsy.
Objective. To study the clinic, diagnosis, and surgical treatment of abnormalities of the prostate gland, seminal tubercle, and seminal vesicles in children.
Material and methods. Over the past 30 years, the staff of the Children’s Surgery Clinic has examined 100.000 children with urological disorders in children’s hospitals and polyclinics in Ryazan and Zaporizhzhia. Forty children (0.04%) were found to have VVPPO. Nineteen children had abnormalities of the prostate gland, seventeen had abnormalities of the seminal tubercle, and four had abnormalities of the seminal vesicles. The diagnosis included medical history, examination, cystoscopy, ureteroscopy, ultrasound, X-ray, CT and MRI scans, and biopsy.
Results. 35 children with CPIGO were operated on. 4 children had their suppurative prostate cysts opened and drained, 17 children had their seminal tubercle resected, 6 children had their retention cysts removed, and 4 children had their cystic vesicle removed. Two clinical cases are presented.
Conclusion. CPIGO in childhood occurs in 0.04% of cases of children with urological pathology. With the introduction of modern diagnostic methods (ultrasound, X-ray, CT and MRI, ureteroscopy and laparoscopy, morphological studies), it became possible to diagnose most of the abnormalities during life, especially when complications occurred. In 80.5% of cases, surgical treatment was successful in children.
