Background: The possibility of having a successful pregnancy in stage V chornic kidney failure improves after transplant, although the fertility rate is lower than in the general population.

Objetive: To evaluate the evolution of the pregnancies among the renal transplanted of a public hospital.

Materials and methods: The whole renal transplanted population of reproductive age women (15-45 years) in our unit was considered. Other aspects such as: registered pregnancies, complications, scheduled pregnancies, serum creatinine at diagnoss, time since transplantation were also considered.

Results: 221 transplanted patients were at some point in the defined age range, with an average time of the follow up of 5.22 years. During the evaluated period seventeen pregnancies were registered, with an incidence density of 0.014 pregnancy/patient in reproductive age/year (13 one pregnancy, 3 two pregnancies). Results are resumen in table 1.

Table 1 First Prenangy Second Pregnancy
Age 27.5±6.9 29.6[divide]6.8
Not programed pregnancy 9/13 3/3
Years after Transplant 3.3±1.5 6.1±4.2
Creatinne 1.8±0.9 2.3±1.7
Spontaneous abortions 3/13 1/3
Live births 9/13 2/3
Gestation weeks at birth 31.6 29.5
Low weight births 8/9 2/2

Only 30.76% of the first pregnancies an 66% of the second one were deliberate. Only 17.64% (3/17) of the pregnancies reachedl the 36th week. Of the 12 born children, elevn survived. All the patients show renal function decay or proteinuriaa after the prenancy. 100% (4/4) of children who were planned pregnancies survived, against the 69.23% (9/13) of the ones who didn't have a programmed labor.

Conclusion: The pregnancy rate in renal transplanted patients in our low income patient is low. Despite of the conversation with them about pregnancy, a high percentage of the pregnancies where not planned, often associated with immunosupresive treatment suspension by the mother. Almost all pregnancies were preterm and associated with low birth with consecuences to the mother´s kidney function. Having a planned pregnancy in transplanted patients is essential.
