Sacral neuromodulation (SNM) is a well-established treatment in the management of refractory overactive bladder (OAB), non-obstructive retention, and fecal incontinence. However, the use and management of SNM in pregnant women remains elusive. We present a noteworthy case involving a patient diagnosed with Clara-Fowler syndrome who underwent SNM during the early stages of pregnancy. The sacral neuromodulator remained activated throughout the pregnancy upon patient's request. After vaginal delivery the patient encountered device dysfunction, ultimately attributed to electrode migration. After repositioning of a new electrode in the contralateral sacral root, the patient successfully recovered spontaneous voiding with no post void residual. This case suggests that SNM may not have detrimental effects on pregnancy or fetal development. However, the intricate physiological changes associated with pregnancy and vaginal delivery may contribute to electrode migration, warranting careful consideration in the management of pregnant patients undergoing SNM.
