The urinary retention is defined as the inability to completely empty the bladder. Among females the prevalence of UR is rare. The treatment of urinary retention is mainly depending on using Sacral Neuromodulator device. Most physicians advise the pregnant women to turn off the device during their pregnancy and labor to keep the mother and infant health. However, our case went against medical advice and kept the device on her responsibility. Unexpectedly the pregnancy was uneventful, and without complication, all labs were within normal range, and no abnormality showed in the imaging. In conclusion, using the Sacral Neuromodulator device during pregnancy and labor may be safe in some cases, but it requires continuous follow-up.
