Acontractile detrusor as an initial presentation of sacral spinal cord lesion: Case series.

Abstract

This study aims to investigate cases of acontractile bladder as the initial presentation of benign and malignant spinal conditions. The focus is on the challenges in making a diagnosis and the importance of a thorough neurological evaluation. We conducted a retrospective case series involving three patients who exhibited symptoms of acontractile bladder. Detailed clinical histories, urodynamic studies, and imaging techniques such as lumbosacral magnetic resonance imaging (MRI) were analyzed. Histopathological findings from relevant biopsies were also taken into account. Case 1: A 14-year-old female presented with urinary retention, back pain, and an acontractile bladder on urodynamic study. Further examination, including lumbosacral MRI and histopathology, confirmed a diagnosis of metastatic Ewing's Sarcoma. Case 2: A 39-year-old female with urinary incontinence and elevated post-void residual exhibited delayed bladder sensation. Lumbar spine MRI revealed a grade I Schwannoma after surgical resection. Case 3: A 15-year-old male with lower urinary tract symptoms and an acontractile detrusor on urodynamic study was found to have a Tarlov cyst on lumbosacral MRI. Atonic or Underactive bladder syndrome may be the initial presentation of a serious spinal condition. Complete neurological evaluation is mandatory if no obvious clinical cause.
