“…The data analysed were: age at presentation, location of the urinoma, gender, underlying urinary obstruction (lower urinary tract (LUT) or upper urinary tract (UUT)) and renal function. All cases of prenatally diagnosed urinoma reported in literature are shown in Table 1, 6–23 while the cases of neonatal urinoma are shown in Tables 2 3,24–38 …”

Prognosis concerning renal function seems to be mainly related to two factors: age at presentation and underlying diagnosis. Decompression of the urinary tract by urine extravasation produces the best results in terms of preservation of the renal function in LUT obstruction (75% in prenatal and 84% in postnatal cases); UUT obstruction however is associated with a good prognosis in the neonatal period (80% of preserved renal function) but with a severe impairment (only 20% of preserved renal function) in prenatally detected cases.

“…The prenatal ultrasound diagnosis of PUV is feasible and has already been reported as early as the 13th week of gestation (Sweeney et al, 1981;Dibbins et al, 1985;Turner, 1985;Helin and Persson, 1986;Silver et al, 1990;Oga et al, 1994;Cochat et al, 1996;Rani et al, 1997;Cohen et al, 1998;Yerkes et al, 2001); since the urethral obstruction is not directly detectable through an ultrasound, the diagnosis of PUV depends, in most instances, upon the recognition of sonographic signs of the lower urinary tract obstruction in a male fetus (dilated bladder, hydronephrosis and renal dysplasia (Figures 1 and 2). Additional inconstant findings are represented by a dilated posterior urethra and bladder wall hypertrophy (Glazer et al, 1982;Hayden et al, 1988).…”

Early prenatal diagnosis of concordant posterior urethral valves in male monochorionic twins

et al. 2005

The association between monozygotic twins and posterior urethral valves (PUV) in postnatal life has been thoroughly described. In the fetus, the prenatal recognition of PUV is feasible. However, it has been repeatedly reported in singletons but never in monochorionic twins. We describe two cases of early prenatal diagnosis of concordant PUVs in monochorionic twins. In one of the sets, the expression of the disease was different for each twin.

“…Review of the literature revealed 25 published cases6–22 of fetuses with a prenatal diagnosis of urinoma. The cases of abdominal fluid mass or fetal hydronephrosis diagnosed as urinomas after birth were not included in this retrospective analysis in order to avoid recruitment bias.…”

Objective To evaluate the functional prognosis of kidneys affected prenatally by urinomas. MethodsThis was a retrospective review of cases of fetal urinoma reported in the literature, as well as two of our own cases. Results Twenty-three patients with a prenatal diagnosis of urinoma (five bilateral) were included in the analysis. Postnatal ipsilateral renal function was observed in only six of the 28 renal units (i.e. around 20%).Conclusions Although the precise causes of urinomas are still unknown, this review shows that in the event of a fetal urinoma, the probability of a non-functional dysplastic ipsilateral kidney lies at around 80%. In-utero puncture only appears to be justified in cases where fluid accumulation has mass effects on adjacent major structures.
