Anticipating and Managing Bladder Function Changes
A recent study reveals that repeat anorectal malformation (ARM) surgery can negatively impact bladder function in some patients, highlighting the need for close urologic monitoring.
ARMs frequently involve neurogenic bladder, where nerve issues impact bladder function. While the standard posterior sagittal anorectoplasty (PSARP) surgery for correcting ARMs is thought to minimally affect bladder dynamics, the effects of reoperative PSARP (rPSARP)—repeat surgery for patients requiring further intervention—are not well studied.
Study Overview
Michael Daugherty, MD, MHI, director of the Healthy Bladder Clinic at Cincinnati Children’s, led a study to assess the influence of rPSARP on bladder function. The study reviewed the medical records of patients who underwent rPSARP between 2008 and 2015.
Researchers focused on patients who received urologic follow-up after surgery. Data analysis included factors like the original severity of ARM, coexisting spinal anomalies (if any) and reasons for rPSARP. Additionally, urodynamic variables and bladder management techniques (voiding, intermittent catheterization or urinary diversion) were evaluated before and after rPSARP.
Key Findings
- The study involved 172 patients, of which 85 met the inclusion criteria.
- Of study subjects, 42% (36 patients) had spinal cord anomalies.
- The most common reasons for rPSARP were misplacement of the surgical repair (42 patients), posterior urethral diverticulum (16 patients), stricture (19 patients) and rectal prolapse (8 patients).
- Within one year following rPSARP, 13% (11 patients) experienced a negative change in bladder management, requiring them to begin intermittent catheterization or undergo urinary diversion. This number increased to 19% (16 patients) at the final follow-up.
- The study suggests that patients who underwent rPSARP for misplacement or stricture were more likely to experience a postoperative decline in bladder function.
