ObjectiveRecent and historical studies suggest that bladder neck procedures (BNPs) without augmentation are safe and effective. In select patients we have performed BNPs without concomitant augmentation. We sought to determine long-term outcomes of this approach and attempt to identify risk factors for bladder deterioration.Patients and methodsA retrospective chart review was conducted to identify patients who underwent a BNP without bladder augmentation and followed for at least 4 years. BNPs were only performed in patients with favorable preoperative urodynamics (UDS). The charts were analyzed for long-term outcomes with the primary endpoint of bladder augmentation.ResultsTwenty-nine patients (21 females) with poor bladder outlet resistance underwent a BNP without augmentation (mean follow-up 8 years). Thirteen patients (45%) were augmented at an average of 2.6 years. No predictive UDS parameters were identified; however, exploratory analysis suggested detrusor pressure at 100 mL bladder volume prior to BNP (p = 0.009) was predictive of delayed augmentation.ConclusionWe report a 45% augmentation rate after isolated BNP in patients with favorable preoperative UDS parameters. We recommend close observation of this patient population with serial UDS, routine ultrasounds, and appropriate preoperative counseling prior to undertaking this approach, as this represents a life-long risk to the upper tracts.
