1/2. 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.

2/2. An unusual case of dantrolene sodium-induced urinary retention in post-traumatic minimally responsive state.

    INTRODUCTION: An unusual case of urinary retention is reported occurring during the inpatient rehabilitation of minimally responsive state (MRS) following severe traumatic brain injury (TBI). CLINICAL PICTURE: Urodynamic evaluation showed detrusor acontractility and subsequent management involved intermittent bladder catheterization and treatment of a single urinary tract infection. TREATMENT: Factors contributing to her bladder paralysis included severe immobility, tetraplegia and treatment of diffuse spasticity with oral dantrolene sodium 250 mg per day. constipation, diabetes and spinal cord injury were absent. In addition, she received unilateral partial sciatic neurolysis with 50% alcohol for severe knee flexor spasticity and intra-muscular Botulinum toxin A to both spastic upper limbs. OUTCOME: Bladder acontractility resolved completely when dantrolene was reduced with subsequent achievement of a catheter-free status and small post-void residual volumes. Repeat urodynamics showed spontaneous detrusor contractions. CONCLUSION: A discussion of possible aetiologic factors for detrusor acontracility following TBI is presented including a brief review of the literature.
