Abstract

Rhabdomyolysis is a potentially life-threatening condition characterized by skeletal muscle breakdown and release of intracellular contents into the systemic circulation. Exertional rhabdomyolysis (ER) most commonly occurs after high-intensity exercise involving large muscle groups, but cases related to lower intensity or repetitive activity have also been reported. We describe a case of acute ER in a previously healthy 36-year-old man who developed the condition after initiating a workout regimen for erectile dysfunction that included gluteal exercises and pelvic floor muscle training (PFMT), including Kegel exercises, demonstrated in YouTube (Google, San Bruno, CA) videos. The patient presented with dark, reddish-brown urine and mild soreness in the hips and lower back several days after a workout consisting of repetitive pelvic floor contractions, glute bridges, and pelvic tilts. He noted that he had difficulty walking two days after completing the exercises, which had resolved by the time of his visit. Physical examination was unremarkable; however, laboratory testing revealed markedly elevated creatine kinase levels (>22,000 U/L) with associated transaminase elevation. Urinalysis demonstrated positive blood on dipstick without microscopic hematuria, consistent with myoglobinuria. The patient was admitted for aggressive intravenous hydration and monitored closely, with gradual improvement in laboratory values during a four-day hospital course and full recovery without…

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
