Giant urinoma in a newborn boy with a posterior urethral valve: A сase report and review

Abstract

Posterior urethral valve is the most common cause of infravesical obstruction in male newborns. Spontaneous rupture of the urinary collecting system with urine extravasation is a rare complication in this group of children. We present a case of urinoma in a patient with a posterior urethral valve at 4 weeks of age with renal insufficiency. The transurethral destruction of the valve and evacuation of the urinoma contributed to the restoration of the urodynamics and recovery of renal function. Urinoma is a rare manifestation of this defect, and its significance for predicting the preservation of renal function has not been fully determined yet. Reports about the occurrence of urine extravasation in the posterior urethral valve and studying kidney function in the long-term period can clarify the significance of this spontaneous mechanism of urinary tract decompression.
