Objectives

To report a rare case of jelly-like urine associated with a urinary tract infection (UTI) and to review relevant literature on its potential causes and clinical significance.

Case Presentation

An 81-year-old male patient presented with lower abdominal discomfort and urethral meatal pain. Urinalysis revealed a yellow, jelly-like urine with high viscosity, accompanied by a significant increase in white blood cells, red blood cells, and bacterial counts. Additional tests confirmed a diagnosis of UTI, with cystitis and renal function abnormalities observed on imaging studies. The patient was treated with antibiotics, resulting in gradual resolution of the jelly-like urine.

Conclusions

Jelly-like urine, though rare, can be a manifestation of a severe UTI with associated renal damage. Other potential causes include dehydration, crystalluria, and certain medications. Clinicians should consider these factors when encountering unusual urine characteristics, especially in elderly patients with underlying conditions. Further studies are needed to better understand the mechanisms underlying jelly-like urine and its clinical implications.
