Acute renal failure associated with dysfunctioning detrusor muscle in multiple sclerosis.
Patients with multiple sclerosis (MS) typically have neurogenic lower urinary tract dysfunction. Most patients present with bladder hyperreflexia and failure to empty the bladder secondary to detrusor-distal sphincter dyssynergia. This case study is unique in the literature in reporting on a patient presenting with acute renal failure (ARF) due to vesico-sphincter dysfunction associated with MS. A 64-year-old man with MS presented in the emergency department with the chief complaint of a marked decrease in urinary output for 2 days and weakness. He had been treated for MS for 7 years. A mass compatible with a full bladder was palpated in the suprapubic region on examination. Digital rectal examination disclosed grade I-Il prostate hypertrophy. Urinary catheters were inserted and urinary output was monitored. The residual urine was drained and recorded as 1100 mL. Initial laboratory findings, such as the BUN/creatinine ratio, urinary sodium concentration, and urine gravity, were compatible with ARF. The patient recovered rapidly in 24 hours following urinary catheterization and prompt medication in the emergency department. He was admitted to the neurology ward with a diagnosis of acute urinary outflow obstruction resulting in ARF due to detrusor dysfunction complicating an MS attack. ARF may complicate the course of patients with MS and associated detrusor-external sphincter dyssynergia. Renal recovery of these patients may be facilitated by urinary catheterization and supportive treatment.
